Description:
CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority to and the benefit of U.S. Provisional Patent Application No. 63/199,679, filed Jan. 15, 2021, titled MULTIPLEXING SYNCHRONIZATION SIGNAL BLOCKS, CONTROL RESOURCE SET, AND SYSTEM INFORMATION BLOCKS, which is hereby incorporated by reference in its entirety as if fully set forth below and for all applicable purposes. 
    
    
     TECHNICAL FIELD 
     The present disclosure is directed to wireless communication systems and methods. Certain aspects can enable and provide techniques for multiplexing synchronization blocks (SSBs), control resource sets (CORESETs), and system information blocks (SIBs). 
     INTRODUCTION 
     Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). A wireless multiple-access communications system may include a number of base stations (BSs), each simultaneously supporting communications for multiple communication devices, which may be otherwise known as user equipment (UE). 
     To meet the growing demands for expanded mobile broadband connectivity, wireless communication technologies are advancing from the long term evolution (LTE) technology to a next generation new radio (NR) technology, which may be referred to as 5 th  Generation (5G). For example, NR is designed to provide a lower latency, a higher bandwidth or a higher throughput, and a higher reliability than LTE. NR is designed to operate over a wide array of spectrum bands, for example, from low-frequency bands below about 1 gigahertz (GHz) and mid-frequency bands from about 1 GHz to about 6 GHz, to high-frequency bands such as millimeter wave (mmWave) bands. NR is also designed to operate across different spectrum types, from licensed spectrum to unlicensed and shared spectrum. Spectrum sharing enables operators to opportunistically aggregate spectrums to dynamically support high-bandwidth services. Spectrum sharing can extend the benefit of NR technologies to operating entities that may not have access to a licensed spectrum. 
     In a wireless communication network, a BS may transmit various system information to facilitate initial network access by UEs. For instance, the BS may periodically transmit synchronization signal blocks (SSB) including various synchronization signals and system information associated with the network. The SSB may also provide information associated with a control resource set (CORESET) where the BS may transmit scheduling information for additional system information. Accordingly, the BS may transmit the scheduling information in the indicated CORESET and transmit the additional system information according to the scheduling information.

     DETAILED DESCRIPTION 
     The detailed description set forth below, in connection with the appended drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts. 
     This disclosure relates generally to wireless communications systems, also referred to as wireless communications networks. In various aspects, the techniques and apparatus may be used for wireless communication networks such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA) networks, LTE networks, Global System for Mobile Communications (GSM) networks, 5 th  Generation (5G) or new radio (NR) networks, as well as other communications networks. As described herein, the terms “networks” and “systems” may be used interchangeably. 
     An OFDMA network may implement a radio technology such as evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM and the like. UTRA, E-UTRA, and GSM are part of universal mobile telecommunication system (UMTS). In particular, long term evolution (LTE) is a release of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents provided from an organization named “3rd Generation Partnership Project” (3GPP), and cdma2000 is described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2). These various radio technologies and standards are known or are being developed. For example, the 3rd Generation Partnership Project (3GPP) is a collaboration between groups of telecommunications associations that aims to define a globally applicable third generation (3G) mobile phone specification. 3GPP long term evolution (LTE) is a 3GPP project which was aimed at improving the UMTS mobile phone standard. The 3GPP may define specifications for the next generation of mobile networks, mobile systems, and mobile devices. The present disclosure is concerned with the evolution of wireless technologies from LTE, 4G, 5G, NR, and beyond with shared access to wireless spectrum between networks using a collection of new and different radio access technologies or radio air interfaces. 
     In particular, 5G networks contemplate diverse deployments, diverse spectrum, and diverse services and devices that may be implemented using an OFDM-based unified, air interface. In order to achieve these goals, further enhancements to LTE and LTE-A are considered in addition to development of the new radio technology for 5G NR networks. The 5G NR will be capable of scaling to provide coverage (1) to a massive Internet of things (IoTs) with a ultra-high density (e.g., ˜1M nodes/km 2 ), ultra-low complexity (e.g., ˜10 s of bits/sec), ultra-low energy (e.g., ˜10+ years of battery life), and deep coverage with the capability to reach challenging locations; (2) including mission-critical control with strong security to safeguard sensitive personal, financial, or classified information, ultra-high reliability (e.g., ˜99.9999% reliability), ultra-low latency (e.g., ˜1 ms), and users with wide ranges of mobility or lack thereof; and (3) with enhanced mobile broadband including extreme high capacity (e.g., ˜10 Tbps/km 2 ), extreme data rates (e.g., multi-Gbps rate, 100+ Mbps user experienced rates), and deep awareness with advanced discovery and optimizations. 
     A 5G NR communication system may be implemented to use optimized OFDM-based waveforms with scalable numerology and transmission time interval (TTI). Additional features may also include having a common, flexible framework to efficiently multiplex services and features with a dynamic, low-latency time division duplex (TDD)/frequency division duplex (FDD) design; and with advanced wireless technologies, such as massive multiple input, multiple output (MIMO), robust millimeter wave (mmWave) transmissions, advanced channel coding, and device-centric mobility. Scalability of the numerology in 5G NR, with scaling of subcarrier spacing, may efficiently address operating diverse services across diverse spectrum and diverse deployments. For example, in various outdoor and macro coverage deployments of less than 3 GHz FDD/TDD implementations, subcarrier spacing may occur with 15 kHz, for example over 5, 10, 20 MHz, and the like bandwidth (BW). For other various outdoor and small cell coverage deployments of TDD greater than 3 GHz, subcarrier spacing may occur with 30 kHz over 80/100 MHz BW. For other various indoor wideband implementations, using a TDD over the unlicensed portion of the 5 GHz band, the subcarrier spacing may occur with 60 kHz over a 160 MHz BW. Finally, for various deployments transmitting with mmWave components at a TDD of 28 GHz, subcarrier spacing may occur with 120 kHz over a 500 MHz BW. 
     The scalable numerology of the 5G NR facilitates scalable TTI for diverse latency and quality of service (QoS) requirements. For example, shorter TTI may be used for low latency and high reliability, while longer TTI may be used for higher spectral efficiency. The efficient multiplexing of long and short TTIs to allow transmissions to start on symbol boundaries. 5G NR also contemplates a self-contained integrated subframe design with UL/downlink scheduling information, data, and acknowledgement in the same subframe. The self-contained integrated subframe supports communications in unlicensed or contention-based shared spectrum, adaptive UL/downlink that may be flexibly configured on a per-cell basis to dynamically switch between UL and downlink to meet the current traffic needs. 
     Various other aspects and features of the disclosure are further described below. It should be apparent that the teachings herein may be embodied in a wide variety of forms and that any specific structure, function, or both being disclosed herein is merely representative and not limiting. Based on the teachings herein one of an ordinary level of skill in the art should appreciate that an aspect disclosed herein may be implemented independently of any other aspects and that two or more of these aspects may be combined in various ways. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, such an apparatus may be implemented or such a method may be practiced using other structure, functionality, or structure and functionality in addition to or other than one or more of the aspects set forth herein. For example, a method may be implemented as part of a system, device, apparatus, and/or as instructions stored on a computer readable medium for execution on a processor or computer. Furthermore, an aspect may comprise at least one element of a claim. 
     As discussed above, NR or 5G may operate over high frequencies, such as mmWave frequency ranges or frequency, to take advantage of availability of wide-bandwidth channels to provision for a higher data throughput than the low frequency bands which are commonly used for conventional wireless communication systems. The mmWave frequency range between about 52.6 gigahertz (GHz) to about 71 GHz is referred to as frequency range 2 (FR2). However, FR2 can have a higher path-loss compared to lower frequency ranges, such as frequency range 1 (FR1) between about 4 GHz to about 7 GHz). To overcome the high path-loss in the FR2, the BS  105  and/or a UE  115  may apply beamforming techniques to form directional beams for transmissions and/or receptions. A directional beam may focus transmit signal energy and/or receive signal energy in a certain spatial direction and within a certain spatial angular sector or width. As used herein, the term “beam sweep” or “beam sweeping” may refer to a transmitter sequentially using each beam of a set of beams for transmissions or a receiver sequentially using each beam of a set of beams for receptions. 
     To facilitate initial network access over FR2 bands, the BS may transmit SSBs in multiple beam directions (using beam sweep) to cover a sector served by the BS. For instance, the BS may transmit a set of SSBs by sweeping through a set of predefined beam directions (using a set of transmission beams at the BS). The set of SSBs may be referred to as an SSB burst set. Each SSB may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and/or a master information block (MIB). A MIB may include system information for initial network access and scheduling information for further system information, which may be referred to as remaining minimum system information (RMSI) or system information blocks (SIBs). For example, the MIB may include an indication of a control resource set (CORESET) where the BS may transmit scheduling information for RMSI. In some instances, a CORESET where SIB scheduling information is transmitted may be referred to as a CORESET 0. 
     When the BS transmits SSBs in multiple beam directions, the BS may configure a CORESET for each of the beam directions. In other words, a CORESET may be associated with a certain beam direction. The BS may transmit SIB scheduling information in each CORESET using a transmission beam directed to the beam direction associated with the CORESET. The SIB scheduling information may indicate a resource allocated for SIB transmission. The BS may transmit SIB(s) as scheduled by the scheduling information in the same beam direction as the SIB scheduling information. In this way, a UE desiring to access a network may monitor for SSBs in multiple beam directions (e.g., using beam sweeping). Upon detecting an SSB providing a received signal quality (e.g., a reference signal received power (RSRP)) that satisfies a certain threshold, the UE may continue to monitor for SIB scheduling information and/or SIB in the same beam direction as the SSB. 
     The present application describes mechanisms for multiplexing SSBs, CORESETs, and SIBs using time-division multiplexing (TDM). In certain aspects, a BS  105  may transmit SSBs of an SSB burst set in groups of SSBs spaced apart in time by gap periods, and may configure and/or schedule CORESETs (e.g., CORESET 0) and SIBs associated with the SSBs within the gap periods. In this regard, the BS  105  transmits a first group of SSBs of the SSB burst set in a first set of consecutive slots and transmits a second group of SSBs of the SSB burst set in a second set of consecutive slots. The first set of consecutive slots is spaced apart from the second set of consecutive slots by a gap. The BS  105  may configure or schedule a group of CORESETs and SIBs in the gap. The group of CORESETs and SIBs may include a set of CORESET/SIB (e.g., one CORESET and at least one SIB) for each SSB of the first group of SSBs. The BS may transmit SIB scheduling information in each CORESET of the group of CORESETs and SIBs for a corresponding SSB. Subsequently, the BS may transmit SIB(s) according to corresponding SIB scheduling information. As described above, the BS may transmit each SSB of an SSB burst set in a certain beam direction. As such, a CORESET associated with a certain SSB may be associated with the same beam direction as the certain SSB. The BS may transmit SIB scheduling information associated with a certain SSB and corresponding SIB(s) in the same beam direction as the certain SSB. 
     In some aspects, the BS  105  may transmit the SSBs in the SSB burst set in resources (e.g., slots) configured based on a first SCS, and schedule and/or configure the CORESETs and SIBs associated with the SSB burst set in resources configured based on a second SCS. In some aspects, the first SCS is different from the second SCS. In some aspects, each SSB may include an SSB index identifying the SSB. Accordingly, a UE may monitor for SSBs based on the first SCS. Upon receiving an SSB, the UE may identify a time location of a CORESET associated with the SSB based on the SSB index (e.g., indicated by the SSB), the first SCS, the second SCS, and/or a slot index associated with the SSB. The UE may monitor for SIB scheduling information in the identified CORESET based on the second SCS. Upon receiving SIB scheduling information, the UE may receive SIBs based on the scheduling information and the second SCS. 
     In certain aspects, the SSB burst set may include 64 SSBs. The BS may transmit the SSB burst set within a 5 milliseconds (ms) time interval and may repeat the transmission of the SSB burst set according to a certain periodicity (e.g., about 10 ms, 20 ms, 40 ms, 80 ms or more). The BS may transmit the SSB burst set in four groups of 16 SSBs. The BS may transmit each group of SSBs in consecutive slots that are spaced apart from a neighboring or adjacent group of SSBs in time. In some instances, the first SCS associated with the SSB burst set is 120 kHz, and each group of 16 SSBs may be transmitted in 8 consecutive slots (defined based on a 120 kHz SCS), for example, with 2 SSBs per slot. The gaps between each of group of SSBs may include 2 slots at the 120 kHz SCS. If the second SCS associated with the CORESETs and SIBs is at 480 kHz, each gap may include 8 slots defined at the 480 kHz SCS and the BS may configure and/or schedule two sets of CORESET/SIB in each slot. If the second SCS associated with the CORESETs and SIBs is at 960 kHz, each gap may include 16 slots defined at the 960 kHz SCS and the BS may configure and/or schedule one set of CORESET/SIB in each slot. In other words, groups of SSBs are time-multiplexed with groups of CORESETs and SIBs. 
     In other aspects, the BS may configure or schedule a group of CORESETs and SIBs for a group of SSBs within the same set of consecutive slots where the group of SSBs. For instance, within each set of consecutive slots, the BS  105  may configure and/or schedule a group of CORESETs/SIBs for every sub-group of two SSBs in a gap period (symbols unoccupied by the SSBs) before the sub-group of two SSBs. 
     Aspects of the present disclosure can provide several benefits. For example, time-multiplexing groups of SSBs with groups of CORESETs and SIBs may allow a UE detecting an SSB with an acceptable received quality (e.g., about a certain threshold) to stop monitoring for further SSBs, compute a time location of an associated CORESET, and enter a low-power mode or a sleep-mode until a starting time of the CORESET. As such, the UE may save power during initial network access. While the present disclosure is discussed in the context of communicating over a mmWave band with SSBs configured for an SCS of 120 kHz and CORESETs and SIBs configured for an SCS of 480 kHz or an SCS of 960 kHz, the present disclosure can be applied for communications in any frequency ranges and with any suitable SCSs. Additionally, while the present disclosure is discussed in the context of an SSB burst set including 64 SSBs, the present disclosure may be applied to an SSB burst set including a smaller number of SSBs or a greater number of SSBs. 
       FIG. 1  illustrates a wireless communication network  100  according to some aspects of the present disclosure. The network  100  may be a 5G network. The network  100  includes a number of base stations (BSs)  105  (individually labeled as  105   a,    105   b,    105   c,    105   d,    105   e,  and  105   f ) and other network entities. A BS  105  may be a station that communicates with UEs  115  (individually labeled as  115   a,    115   b,    115   c,    115   d,    115   e,    115   f,    115   g,    115   h,  and  115   k ) and may also be referred to as an evolved node B (eNB), a next generation eNB (gNB), an access point, and the like. Each BS  105  may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to this particular geographic coverage area of a BS  105  and/or a BS subsystem serving the coverage area, depending on the context in which the term is used. 
     ABS  105  may provide communication coverage for a macro cell or a small cell, such as a pico cell or a femto cell, and/or other types of cell. A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a pico cell, would generally cover a relatively smaller geographic area and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a femto cell, would also generally cover a relatively small geographic area (e.g., a home) and, in addition to unrestricted access, may also provide restricted access by UEs having an association with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs for users in the home, and the like). A BS for a macro cell may be referred to as a macro BS. A BS for a small cell may be referred to as a small cell BS, a pico BS, a femto BS or a home BS. In the example shown in  FIG. 1 , the BSs  105   d  and  105   e  may be regular macro BSs, while the BSs  105   a - 105   c  may be macro BSs enabled with one of three dimension (3D), full dimension (FD), or massive MIMO. The BSs  105   a - 105   c  may take advantage of their higher dimension MIMO capabilities to exploit 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. The BS  105   f  may be a small cell BS which may be a home node or portable access point. ABS  105  may support one or multiple (e.g., two, three, four, and the like) cells. 
     The network  100  may support synchronous or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the BSs may have different frame timing, and transmissions from different BSs may not be aligned in time. 
     The UEs  115  are dispersed throughout the wireless network  100 , and each UE  115  may be stationary or mobile. A UE  115  may also be referred to as a terminal, a mobile station, a subscriber unit, a station, or the like. A UE  115  may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a wireless local loop (WLL) station, or the like. In one aspect, a UE  115  may be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, a UE may be a device that does not include a UICC. In some aspects, the UEs  115  that do not include UICCs may also be referred to as IoT devices or internet of everything (IoE) devices. The UEs  115   a - 115   d  are examples of mobile smart phone-type devices accessing network  100 . A UE  115  may also be a machine specifically configured for connected communication, including machine type communication (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT) and the like. The UEs  115   e - 115   h  are examples of various machines configured for communication that access the network  100 . The UEs  115   i - 115   k  are examples of vehicles equipped with wireless communication devices configured for communication that access the network  100 . A UE  115  may be able to communicate with any type of the BSs, whether macro BS, small cell, or the like. In  FIG. 1 , a lightning bolt (e.g., communication links) indicates wireless transmissions between a UE  115  and a serving BS  105 , which is a BS designated to serve the UE  115  on the downlink (DL) and/or uplink (UL), desired transmission between BSs  105 , backhaul transmissions between BSs, or sidelink transmissions between UEs  115 . 
     In operation, the BSs  105   a - 105   c  may serve the UEs  115   a  and  115   b  using 3D beamforming and coordinated spatial techniques, such as coordinated multipoint (CoMP) or multi-connectivity. The macro BS  105   d  may perform backhaul communications with the BSs  105   a - 105   c,  as well as small cell, the BS  105   f.  The macro BS  105   d  may also transmits multicast services which are subscribed to and received by the UEs  115   c  and  115   d.  Such multicast services may include mobile television or stream video, or may include other services for providing community information, such as weather emergencies or alerts, such as Amber alerts or gray alerts. 
     The BSs  105  may also communicate with a core network. The core network may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the BSs  105  (e.g., which may be an example of a gNB or an access node controller (ANC)) may interface with the core network through backhaul links (e.g., NG-C, NG-U, etc.) and may perform radio configuration and scheduling for communication with the UEs  115 . In various examples, the BSs  105  may communicate, either directly or indirectly (e.g., through core network), with each other over backhaul links (e.g., X1, X2, etc.), which may be wired or wireless communication links. 
     The network  100  may also support mission critical communications with ultra-reliable and redundant links for mission critical devices, such as the UE  115   e,  which may be a drone. Redundant communication links with the UE  115   e  may include links from the macro BSs  105   d  and  105   e,  as well as links from the small cell BS  105   f.  Other machine type devices, such as the UE  115   f  (e.g., a thermometer), the UE  115   g  (e.g., smart meter), and UE  115   h  (e.g., wearable device) may communicate through the network  100  either directly with BSs, such as the small cell BS  105   f,  and the macro BS  105   e,  or in multi-step-size configurations by communicating with another user device which relays its information to the network, such as the UE  115   f  communicating temperature measurement information to the smart meter, the UE  115   g,  which is then reported to the network through the small cell BS  105   f.  The network  100  may also provide additional network efficiency through dynamic, low-latency TDD/FDD communications, such as V2V, V2X, C-V2X communications between a UE  115   i,    115   j,  or  115   k  and other UEs  115 , and/or vehicle-to-infrastructure (V2I) communications between a UE  115   i,    115   j,  or  115   k  and a BS  105 . 
     In some implementations, the network  100  utilizes OFDM-based waveforms for communications. An OFDM-based system may partition the system BW into multiple (K) orthogonal subcarriers, which are also commonly referred to as subcarriers, tones, bins, or the like. Each subcarrier may be modulated with data. In some instances, the subcarrier spacing between adjacent subcarriers may be fixed, and the total number of subcarriers (K) may be dependent on the system BW. The system BW may also be partitioned into subbands. In other instances, the subcarrier spacing and/or the duration of TTIs may be scalable. 
     In some aspects, the BSs  105  can assign or schedule transmission resources (e.g., in the form of time-frequency resource blocks (RB)) for downlink (DL) and uplink (UL) transmissions in the network  100 . DL refers to the transmission direction from a BS  105  to a UE  115 , whereas UL refers to the transmission direction from a UE  115  to a BS  105 . The communication can be in the form of radio frames. A radio frame may be divided into a plurality of subframes or slots, for example, about 10. Each slot may be further divided into mini-slots. In a FDD mode, simultaneous UL and DL transmissions may occur in different frequency bands. For example, each subframe includes a UL subframe in a UL frequency band and a DL subframe in a DL frequency band. In a TDD mode, UL and DL transmissions occur at different time periods using the same frequency band. For example, a subset of the subframes (e.g., DL subframes) in a radio frame may be used for DL transmissions and another subset of the subframes (e.g., UL subframes) in the radio frame may be used for UL transmissions. 
     The DL subframes and the UL subframes can be further divided into several regions. For example, each DL or UL subframe may have pre-defined regions for transmissions of reference signals, control information, and data. Reference signals are predetermined signals that facilitate the communications between the BSs  105  and the UEs  115 . For example, a reference signal can have a particular pilot pattern or structure, where pilot tones may span across an operational BW or frequency band, each positioned at a pre-defined time and a pre-defined frequency. For example, a BS  105  may transmit cell specific reference signals (CRSs) and/or channel state information—reference signals (CSI-RSs) to enable a UE  115  to estimate a DL channel. Similarly, a UE  115  may transmit sounding reference signals (SRSs) to enable a BS  105  to estimate a UL channel. Control information may include resource assignments and protocol controls. Data may include protocol data and/or operational data. In some aspects, the BSs  105  and the UEs  115  may communicate using self-contained subframes. A self-contained subframe may include a portion for DL communication and a portion for UL communication. A self-contained subframe can be DL-centric or UL-centric. A DL-centric subframe may include a longer duration for DL communication than for UL communication. A UL-centric subframe may include a longer duration for UL communication than for UL communication. 
     In some aspects, the network  100  may be an NR network deployed over a licensed spectrum. The BSs  105  can transmit synchronization signals (e.g., including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)) in the network  100  to facilitate synchronization. The BSs  105  can broadcast system information associated with the network  100  (e.g., including a master information block (MIB), remaining system information (RMSI), and other system information (OSI)) to facilitate initial network access. In some instances, the BSs  105  may broadcast the PSS, the SSS, and/or the MIB within a physical broadcast channel (PBCH). The PSS, SSS, and MIB may be transmitted in the form of synchronization signal block (SSBs) and may broadcast the RMSI and/or the OSI over a physical downlink shared channel (PDSCH). 
     In some aspects, a UE  115  attempting to access the network  100  may perform an initial cell search by detecting a PSS from a BS  105 . The PSS may enable synchronization of period timing and may indicate a physical layer identity value. The UE  115  may then receive a SSS. The SSS may enable radio frame synchronization, and may provide a cell identity value, which may be combined with the physical layer identity value to identify the cell. The PSS and the SSS may be located in a central portion of a carrier or any suitable frequencies within the carrier. 
     After receiving the PSS and SSS, the UE  115  may receive a PBCH signal and may decode a MIB from the PBCH signal. The MIB may include system information for initial network access and scheduling information for RMSI and/or OSI. After decoding the MIB, the UE  115  may receive RMSI and/or OSI. The RMSI and/or OSI may include radio resource control (RRC) information related to random access channel (RACH) procedures, paging, control resource set (CORESET) for physical downlink control channel (PDCCH) monitoring, physical UL control channel (PUCCH), physical UL shared channel (PUSCH), power control, and SRS. 
     After obtaining the MIB, the RMSI and/or the OSI, the UE  115  can perform a random access procedure to establish a connection with the BS  105 . In some examples, the random access procedure may be a four-step random access procedure. For example, the UE  115  may transmit a random access preamble and the BS  105  may respond with a random access response. The random access response (RAR) may include a detected random access preamble identifier (ID) corresponding to the random access preamble, timing advance (TA) information, a UL grant, a temporary cell-radio network temporary identifier (C-RNTI), and/or a backoff indicator. Upon receiving the random access response, the UE  115  may transmit a connection request to the BS  105  and the BS  105  may respond with a connection response. The connection response may indicate a contention resolution. In some examples, the random access preamble, the RAR, the connection request, and the connection response can be referred to as message 1 (MSG1), message 2 (MSG2), message 3 (MSG3), and message 4 (MSG4), respectively. In some examples, the random access procedure may be a two-step random access procedure, where the UE  115  may transmit a random access preamble and a connection request in a single transmission and the BS  105  may respond by transmitting a random access response and a connection response in a single transmission. The combined random access preamble and connection request in the two-step random access procedure may be referred to as a message A (MSG A). The combined random access response and connection response in the two-step random access procedure may be referred to as a message B (MSG B). 
     After establishing a connection, the UE  115  and the BS  105  can enter a normal operation stage, where operational data may be exchanged. For example, the BS  105  may schedule the UE  115  for UL and/or DL communications. The BS  105  may transmit UL and/or DL scheduling grants to the UE  115  via a PDCCH. The BS  105  may transmit a DL communication signal to the UE  115  via a PDSCH according to a DL scheduling grant. The UE  115  may transmit a UL communication signal to the BS  105  via a PUSCH and/or PUCCH according to a UL scheduling grant. The connection may be referred to as an RRC connection. When the UE  115  is actively exchanging data with the BS  105 , the UE  115  is in an RRC connected state. 
     In an example, after establishing a connection with the BS  105 , the UE  115  may initiate an initial network attachment procedure with the network  100 . The BS  105  may coordinate with various network entities or fifth generation core (5GC) entities, such as an access and mobility function (AMF), a serving gateway (SGW), and/or a packet data network gateway (PGW), to complete the network attachment procedure. For example, the BS  105  may coordinate with the network entities in the 5GC to identify the UE, authenticate the UE, and/or authorize the UE for sending and/or receiving data in the network  100 . In addition, the AMF may assign the UE with a group of tracking areas (TAs). Once the network attach procedure succeeds, a context is established for the UE  115  in the AMF. After a successful attach to the network, the UE  115  can move around the current TA. For tracking area update (TAU), the BS  105  may request the UE  115  to update the network  100  with the UE  115 &#39;s location periodically. Alternatively, the UE  115  may only report the UE  115 ′s location to the network  100  when entering a new TA. The TAU allows the network  100  to quickly locate the UE  115  and page the UE  115  upon receiving an incoming data packet or call for the UE  115 . 
     In some aspects, the BS  105  may communicate with a UE  115  using hybrid automatic repeat request (HARQ) techniques to improve communication reliability, for example, to provide a URLLC service. The BS  105  may schedule a UE  115  for a PDSCH communication by transmitting a DL grant in a PDCCH. The BS  105  may transmit a DL data packet to the UE  115  according to the schedule in the PDSCH. The DL data packet may be transmitted in the form of a transport block (TB). If the UE  115  decodes the DL data packet successfully, the UE  115  may transmit a HARQ acknowledgement (ACK) to the BS  105 . Conversely, if the UE  115  fails to decode the DL transmission successfully, the UE  115  may transmit a HARQ negative-acknowledgement (NACK) to the BS  105 . Upon receiving a HARQ NACK from the UE  115 , the BS  105  may retransmit the DL data packet to the UE  115 . The retransmission may include the same coded version of DL data as the initial transmission. Alternatively, the retransmission may include a different coded version of the DL data than the initial transmission. The UE  115  may apply soft-combining to combine the encoded data received from the initial transmission and the retransmission for decoding. The BS  105  and the UE  115  may also apply HARQ for UL communications using substantially similar mechanisms as the DL HARQ. 
     In some aspects, the network  100  may operate over a system BW or a component carrier (CC) BW. The network  100  may partition the system BW into multiple BWPs (e.g., portions). ABS  105  may dynamically assign a UE  115  to operate over a certain BWP (e.g., a certain portion of the system BW). The assigned BWP may be referred to as the active BWP. The UE  115  may monitor the active BWP for signaling information from the BS  105 . The BS  105  may schedule the UE  115  for UL or DL communications in the active BWP. In some aspects, a BS  105  may assign a pair of BWPs within the CC to a UE  115  for UL and DL communications. For example, the BWP pair may include one BWP for UL communications and one BWP for DL communications. 
       FIG. 2  is a timing diagram illustrating a radio frame structure  200  according to some aspects of the present disclosure. The radio frame structure  200  may be employed by BSs such as the BSs  105  and UEs such as the UEs  115  in a network such as the network  100  for communications. In particular, the BS may communicate with the UE using time-frequency resources configured as shown in the radio frame structure  200 . In  FIG. 2 , the x-axes represent time in some arbitrary units and the y-axes represent frequency in some arbitrary units. The radio frame structure  200  includes a radio frame  201 . The duration of the radio frame  201  may vary depending on the aspects. In an example, the radio frame  201  may have a duration of about ten milliseconds. The radio frame  201  includes M number of slots  202 , where M may be any suitable positive integer. In an example, M may be about  10 . 
     Each slot  202  includes a number of subcarriers  204  in frequency and a number of symbols  206  in time. The number of subcarriers  204  and/or the number of symbols  206  in a slot  202  may vary depending on the aspects, for example, based on the channel bandwidth, the subcarrier spacing (SCS), and/or the CP mode. One subcarrier  204  in frequency and one symbol  206  in time forms one resource element (RE)  212  for transmission. A resource block (RB)  210  is formed from a number of consecutive subcarriers  204  in frequency and a number of consecutive symbols  206  in time. 
     In some aspects, a BS (e.g., BS  105  in  FIG. 1 ) may schedule a UE (e.g., UE  115  in  FIG. 1 ) for UL and/or DL communications at a time-granularity of slots  202  or mini-slots  208 . Each slot  202  may be time-partitioned into K number of mini-slots  208 . Each mini-slot  208  may include one or more symbols  206 . The mini-slots  208  in a slot  202  may have variable lengths. For example, when a slot  202  includes N number of symbols  206 , a mini-slot  208  may have a length between one symbol  206  and (N−1) symbols  206 . In some aspects, a mini-slot  208  may have a length of about two symbols  206 , about four symbols  206 , or about seven symbols  206 . In some examples, the BS may schedule UE at a frequency-granularity of a resource block (RB)  210  (e.g., including about 12 subcarriers  204  in 1 symbol, 2 symbols, . . . , or 14 symbols). 
     As described above, a BS  105  may transmit SSBs to facilitate a UE  115  in performing an initial network access. Each SSB includes a PBCH carrying a MIB indicating information associated with a CORESET 0 where a PDCCH type 0 may be located. The BS may transmit RMSI scheduling information in the PDCCH type 0 (the CORESET 0). The scheduling information may indicate a resource in a PDSCH where the BS may transmit RMSI.  FIGS. 3-5  illustrate various multiplexing patterns for multiplexing SSBs, CORESET 0, and PDSCH for RMSI. In  FIGS. 3-5 , the x-axes represent time, and the y-axes represent frequency. 
       FIG. 3  illustrates a system information multiplexing scheme  300  according to some aspects of the present disclosure. The scheme  300  may be employed by the network  100 . In particular, a BS (e.g., the BSs  105 ) may employ the scheme  300  to transmit SSBs, RMSI scheduling information, and RMSI in the network as shown in the scheme  300 . The scheme  300  may be used in conjunction with the radio frame structure  200  described above with respect to  FIG. 2 . For simplicity&#39;s sake,  FIG. 3  may use the same reference numerals as in  FIG. 2 . 
     In the scheme  300 , a BS  105  multiplexes an SSB  310 , a CORESET  320  associated with RMSI scheduling, and a PDSCH  330  for RMSI transmission using time-division multiplexing (TDM). As shown in  FIG. 3 , the SSB  310 , the CORESET  320 , and the PDSCH  330  are located at different time periods  302 ,  304 , and  306 , respectively. In some aspects, the SSB  310 , the CORESET  320  and the PDSCH  330  may located within may be located within the same slot  202 . In some other aspects, the SSB  310  may be in one slot  202 , and the CORESET  320  and the PDSCH  330  may be in another slot  202 . In some aspects, the SSB  310 , the CORESET  320  and the PDSCH  330  may located within an initial DL BWP  308 . The initial DL BWP  308  is a default BWP used for a UE  115  during an initial access (before an RRC connection is established). The SSB  310  may include a PSS, an SSS, and a MIB. The SSB  310  may include a pointer, an indication, and/or a configuration (e.g., in a MIB) indicating the CORESET  320  as shown by the arrow  312 . The CORESET  320  may be referred to as a CORESET 0 where a PDCCH type 0 may be located. The CORESET  320  may include time-frequency resources (e.g., including one or more subcarriers  204  in frequency and one or more symbols  206  in time or one or more resource blocks  210 ). The BS may transmit RMSI scheduling information  322  in the CORESET  320  (a PDCCH type 0). The RMSI scheduling information  322  may indicate time-frequency resources (e.g., including one or more subcarriers  204  in frequency and one or more symbols  206  in time or one or more resource blocks  210 ) where the BS  105  may transmit RMSI  332  and/or other transmission parameters related to the transmission of the RMSI  332 . The RMSI  332  may include one or more SIBs (e.g., the SIB 1, SIB 2, etc.) providing various information (e.g., PRACH configurations) to facilitate communication with the network. In some instances, the RMSI scheduling information  322  may also be referred to as SIB scheduling information. 
       FIG. 4  illustrates a system information multiplexing scheme  400  according to some aspects of the present disclosure. The scheme  400  may be employed by the network  100 . In particular, a BS (e.g., the BSs  105 ) may employ the scheme  400  to transmit SSBs, RMSI scheduling information, and RMSI in the network. The scheme  400  may be used in conjunction with the radio frame structure  200  described above with respect to  FIG. 2 . The scheme  400  is described using the same system information signaling structure as in the scheme  300  and may use the same reference numerals as in  FIG. 3  for simplicity&#39;s sake. 
     In the scheme  400 , a BS  105  multiplexes the SSB  310  with the RMSI CORESET  320  and the PDSCH  330  using frequency-division multiplexing (FDM). As shown in  FIG. 4 , the CORESET  320  is located in a frequency band  406  within the initial DL BWP  308  during a time period  402 , the PDSCH  330  is located in the same frequency band  406  during a time period  404 , and the SSB  310  is located in a frequency band  407  non-overlapping with the frequency band  406  during the same time period  404 . In some aspects, the SSB  310 , the CORESET  320  and the PDSCH  330  may located within may be located within the same slot  202 . In some other aspects, the SSB  310  and the PDSCH  330  may be in one slot  202 , and the CORESET  320  may be in another slot  202 . Similar to the scheme  300 , the SSB  310  may include a pointer, an indication, and/or a configuration indicating a location of the CORESET  320  where RMSI scheduling information  322  may be transmitted. 
       FIG. 5  illustrates a system information multiplexing scheme  500  according to some aspects of the present disclosure. The scheme  500  may be employed by the network  100 . In particular, a BS (e.g., the BSs  105 ) may employ the scheme  500  to transmit SSBs, RMSI scheduling information, and RMSI in the network. The scheme  500  may be used in conjunction with the radio frame structure  200  described above with respect to  FIG. 2 . The scheme  500  is described using the same system information signaling structure as in the scheme  300  and may use the same reference numerals as in  FIG. 3  for simplicity&#39;s sake. 
     In the scheme  500 , a BS  105  may multiplex an SSB  310  (e.g., the SSBs  310 ) with the RMSI CORESET  320  and the PDSCH  330  using FDM. The CORESET  320  and the PDSCH  330  are located in a frequency band  506  within an initial active DL BWP  308  during a time period  502 . The SSB  310  is located in a frequency band  507  non-overlapping with the frequency band  506  during the same time period  502 . Similar to the schemes  300  and  400 , the SSB  310  may include a pointer, an indication, and/or a configuration may indicate a location of the CORESET  320  where RMSI scheduling information  322  may be transmitted. 
     In some aspects, the schemes  300 ,  400 , and  500  may be referred to as patterns 1, 2, and 3 respectively. The network  100  may utilize any one of the patterns 1, 2, or 3 for communications over a FR1 band or a FR2 band. In certain aspects, the network  100  may use the same numerology (e.g., the same SCS) for SSB transmissions, CORESET 0 configurations, and RMSI transmissions. In other aspects, the network  100  may use one numerology (e.g., a first SCS) for SSB transmissions and another numerology (e.g., a second, different SCS) for CORESET 0 configurations and RMSI transmissions. In some examples, in an FR1 band, the BS  105  may transmit SSBs using an SCS of 15 kHz or 30 kHz, and may configure CORESET 0 and transmit RMSI using an SCS of 15 kHz or 30 KHz. Thus, there are 4 combinations for configuration and/or transmission of SSB/CORESET/RMSI in FR1 band. In an FR2 band, the BS  105  may transmit SSBs using an SCS of 120 kHz or 240 kHz, and may configure CORESET 0 and transmit RMSI using an SCS of 60 kHz or 120 kHz. Thus, there are also 4 combinations for configuration and/or transmission of SSB/CORESET/RMSI in FR2 bands. In some aspects, the BS  105  may utilize pattern 1 (e.g., the scheme  300 ) for any of the 8 SSB/CORESET/RMSI combinations (e.g., 4 combination for FR1 and 4 combinations for FR2). The BS  105  may utilize pattern 2 (e.g., the scheme  400 ) for some of the SSB/CORESET/RMSI configurations in FR2, for example, for SSBs based on SCS  120  kHz and CORESET/RMSI based on 60 kHz SCS. The BS  105  may utilize pattern 3 for the configuration where SSB/CORESET/RMSI are all based on an SCS of 120 kHz. 
     In some aspects, the network  100  may operate over a high-frequency band, for example, in a frequency range 2 (FR2) band, and may use different numerologies (e.g., different SCSs) for SSB transmission, CORESET 0, and RMSI transmission. In some aspects, a BS  105  may utilize a first SCS (e.g., 120 kHz) for SSB transmission and a second, different SCS of (e.g., 480 kHz or 960 kHz) for CORESET 0 configuration and RMSI transmission. Further, due to the high path-loss in the FR2 band, the BS  105  and/or a UE  115  may apply beamforming techniques to form directional beams for transmissions and/or receptions. In this regard, a BS  105  and/or a UE  115  may be equipped with one or more antenna panels or antenna arrays with antenna elements that can be configured to focus transmit signal energy and/or receive signal energy in a certain spatial direction and within a certain spatial angular sector or width. A beam used for such wireless communications may be referred to as an active beam, a best beam, or a serving beam. 
     In some aspects, the BS  105  may transmit a set of SSBs (e.g., the SSBs  310 ) in a set of predefined beam directions. The set of SSBs may be referred to as an SSB burst set. For instance, the BS  105  may transmit the set of SSBs by sweeping through the set of predefined beam directions (using a set of transmission beams at the BS  105 ). At the same time, the UE may determine an optimal reception beam based on the SSB beams. For instance, the UE may sweep through a set of beam directions (using a set of reception beams at the UE  115 ) to monitor for SSB from the BS  105 . Upon determining the optimal reception beam, the UE may initiate a random access procedure with the BS using the determined reception beam. Upon completing the random access procedure, the UE  115  and the BS  105  may establish a connection with each other. 
     In some aspects, the set of predefined beam directions may correspond to a set of spatial angular sectors covering a sector served by the BS  105 . Accordingly, the BS  105  may transmit an SSB in each of the predefined beam directions to cover the serving sector. A UE  115  located within the serving sector and/or range of the BS  105  may monitor for SSBs and may receive one or more of the SSBs. While each SSB in an SSB burst set may include similar or identical system information related to the network  100 , each SSB may include a different SSB index that uniquely identifies each SSB within the SSB burst set. As an example, the SSB burst set may include 64 SSBs each transmitted in a different beam direction within a serving sector of the BS  105 . The SSBs may be sequentially indexed from 0 to 63. As such, the SSB index may also be associated with a beam direction in which the BS  105  transmitted the SSB. As described above, an SSB may include an indication of a CORESET 0 where RMSI scheduling information (e.g., RMSI scheduling information  322 ) may be transmitted. When beamforming is applied, the CORESET 0 may be associated with the same beam direction as a corresponding SSB. In other words, the BS  105  may transmit RMSI scheduling information  322  in the CORESET 0 indicated by the SSB using a beam directing to the same beam direction as the SSB. The BS  105  may also transmit RMSI (e.g., the RMSI  332 ) scheduled by the RMSI scheduling information in the same beam direction as the SSB. In other words, each SSB in the set of SSBs is associated with a CORESET 0 (e.g., the CORESET  320 ) and RMSI (e.g., the RMSI  332 ). In this way, when a UE  115  determines a beam direction with an SSB having a receive quality (e.g., RSRP) satisfying a threshold, the UE  115  may continue to monitor for RMSI scheduling information and RMSI in the same beam direction where the SSB is received. 
     According to aspects of the present disclosure, a BS  105  may transmit SSBs of an SSB burst set in groups of SSBs spaced apart from each other in time by gap periods, and may configure and/or schedule CORESETs 0 and SIBs associated with the SSBs within the gap periods. For instance, the BS  105  transmits a first group of SSBs of the SSB burst set in a first set of consecutive slots and transmits a second group of SSBs of the SSB burst set in a second set of consecutive slots as will be discussed more fully below with reference to  FIG. 6 . The first set of consecutive slots is spaced apart from the second set of consecutive slots by a gap. The BS  105  may configure or schedule a group of CORESETs and SIBs in the gap, where the group of CORESETs and SIBs includes one CORESET (e.g., CORESET 0) and at least one SIB for each SSB of the first group of SSBs as will be discussed more fully below with reference to  FIGS. 7A-7B and 8A-8B . In some other instances, the BS  105  configure or schedule a group of CORESETs and SIBs for a group of SSBs within the same set of consecutive slots where the group of SSBs is transmitted as will discussed more fully below with reference to  FIGS. 14A-14B and 15A-15B . In some aspects, the BS  105  may transmit the SSBs in the SSB burst set based on a first SCS, and schedule and/or configure the CORESETs and SIBs associated with the SSB burst set based on a second SCS. In some aspects, the first SCS is the same as the second SCS. In some other aspects, the first SCS is different from the second SCS. For example, the first SCS is  120  kHz and the second SCS is  480  kHz as will be discussed more fully below with reference to  FIGS. 7A-7B and 14A-14B . In another example, the first SCS is 120 kHz and the second SCS is 960 kHz as will be discussed more fully below with reference to  FIGS. 8A-8B and 15A-15B . 
       FIG. 6  illustrates an SSB transmission scheme  600  according to some aspects of the present disclosure. The scheme  600  may be employed by BSs such as the BSs  105  and UEs such as the UEs  115  in a network such as the network  100  for communications. In particular, the BS  105  may transmit SSBs (e.g., the SSBs  310 ) of an SSB burst set based on a first SCS (e.g., 120 kHz) as shown in the scheme  600 . In  FIG. 6 , the x-axis represents time in some arbitrary units. 
     In the scheme  600 , the BS  105  may transmit a set of SSBs (an SSB burst set) periodically. In the example illustrated in  FIG. 6 , the BS  105  may transmit a set of SSBs (e.g., an SSB burst set) within a 5 ms window and may repeat the transmission of the set of SSBs at every time period  602 . In some examples, the time period  602  may have a duration of about 20 ms. In other examples, the time period  602  may have a duration of about 40 ms, 80 ms, 160 ms or more. The time period  602  may include a plurality of slots  604  similar to the slots  202  of  FIG. 2   
     For an SCS of 120 kHz, a slot  604  including 14 OFDM symbols may span a duration of about 0.125 ms. As such, there may be about eight slots  604  in each 1 ms time interval as shown by the expanded view  601 . As an example, the set of SSBs may include 64 SSBs), and the BS  105  may partition the set of SSBs into about four groups of SSBs, each including 16 SSBs. The BS  105  may transmit each group of SSBs in eight consecutive slots  604  and may leave a time gap period  605  of about two slots  604  between neighboring or adjacent groups of SSBs. In the expanded view  601 , the slots  604  that are shown as pattern-filled boxes may carry SSBs, and the slots  604  that are shown as empty boxes are the gap periods  605 . As shown, the BS  105  transmits a first group of SSBs  610  in a first set of consecutive slots  604 , a second group of SSBs  620  in a second set of consecutive slots  604 , a third group of SSBs  630  in a third set of consecutive slots  604 , and a fourth group of SSBs  640  in a fourth set of consecutive slots  604 , where each group of SSBs  610  is spaced apart from a neighboring or adjacent group of SSBs by a gap period  605 . 
     An expanded view  603  is shown for the first two slots  604  (e.g., in a duration  606  of 0.25 ms) in the time period  602 . In the expanded view  603 , symbols  608  in the first two slots  604  are indexed from 0 to 27. The BS  105  may transmit  4  SSBs of the first group of SSBs  610  (individually shown as  610   a,    610   b,    610   c,  and  610   d ) in the duration  606 . The BS  105  may transmit each SSB  610   a,    610   b,    610   c,    610   d  over four symbols  608 . More specifically, the BS  105  may transmit the SSB  610   a  in the symbols  608  indexed 4-7, the SSB  610   b  in the symbols  608  indexed 8-11, the SSB  610   c  in the symbols  608  indexed 16-19, and the SSB  610   d  in the symbols  608  indexed 20-23. 
     Each SSB in the SSB set may include an SSB index that uniquely identifies the SSB within the SSB set. In some aspects, the SSBs may be arranged in a sequential order according to the SSB indices. For instance, the SSB  610   a  may include an SSB index 0, the SSB  610   b  may include an SSB index 1, the SSB  610   c  may include an SSB index 2, and the SSB  610   d  may include an SSB index 3. In some other aspects, the SSBs may be arranged in a different order. The BS  105  may transmit the remaining SSBs in the SSB set in a similar manner in the slots  604  shown by the pattern-filled boxes. The starting symbol locations for the SSBs in the SSB set may be expressed as shown below:

     where n={0, 1, 2, 3}, {5, 6, 7, 8}, {10, 11, 12, 13}, {15, 16, 17, 18}. As such, the BS  105  may complete the transmission of the 64 SSBs in the SSB set within the first 5 ms time of the time period  602 . 
       FIG. 7A  illustrates a system information multiplexing scheme  700 A according to some aspects of the present disclosure. The scheme  700 A may be employed by BSs such as the BSs  105  and UEs such as the UEs  115  in a network such as the network  100  for communications. In particular, the BS  105  may multiplex SSBs (e.g., the SSBs  310 ) transmitted based on a first SCS  701  (e.g., 120 kHz) with CORESET 0 (e.g., the CORESET  320 ) and SIBs (e.g., the RMSI  332 ) configured or scheduled based on a second SCS  702  (e.g., 480 kHz) as shown in the scheme  700 A. In  FIG. 7A , the x-axis represents time in some arbitrary units. The scheme  700 A is described using the same SSB transmission structure as in the scheme  600  and may use the same reference numerals as in  FIG. 6  for simplicity&#39;s sake. 
     As described above, the BS  105  may time-multiplex SSBs and associated CORESETs (CORESET 0) in units of SSB groups and CORESET/SIB groups. In the scheme  700 A, the BS  105  may configure a group of CORESETs and SIBs associated with a group of SSBs in a gap period  605  after the group of SSBs. For instance, the BS  105  may transmit a group of SSBs  610  in consecutive slots and may configure and/or schedule CORESETs and SIBs associated with the group of SSBs  610  in the gap period  605  subsequent to the group of SSBs  610 . Similarly, the BS  105  may transmit a group of SSBs  620  in consecutive slots and may configure CORESETs and SIBs associated with the group of SSBs  620  in the gap period  605  subsequent to the group of SSBs  620 . The BS  105  may transmit a group of SSBs  630  in consecutive slots and may configure CORESETs and SIBs associated with the group of SSBs  630  in the gap period  605  subsequent to the group of SSBs  630 . The BS  105  may transmit a group of SSBs  640  in consecutive slots and may configure CORESETs and SIBs associated with the group of SSBs  640  in the gap period  605  subsequent to the group of SSBs  640 . 
     As shown by the expanded view  703 , a gap period  605  including two slots  604  at the first SCS  701  of 120 kHz may include eight slots  704  (each with 14 symbols  708 ) at the second SCS  702  of 480 kHz. In other words, if the slots  704  are indexed beginning at index 0 (at the start of time period  602 ), the eight slots  704  in the gap period  605  may correspond to slots with slot indices 32 to 39 at the second SCS  702  of 480 kHz. The BS  105  may configure two CORESETs (CORESET 0) in each slot  704 . With eight slots  704  in each gap period  605 , the BS  105  may configure 16 CORESETs in each gap period  605 . Each CORESET may correspond to one of the SSBs in a group of SSBs transmitted in preceding slots  604 . More specifically, the BS  105  may configure the CORESETs in the same sequential order across the gap period  605  as the SSBs. For instance, the BS  105  may configure a first CORESET for an SSB with an SSB index 0, followed by a second CORESET for an SSB with an SSB index 1, followed by a third CORESET for an SSB with an SSB index 2, and so on in a timeline across the gap period  605 . 
     In the expanded view  705 , symbols  708  in the first slot  704  of the gap period  605  are indexed from 0 to 13. In the example illustrated in  FIG. 7A , the BS  105  configures a CORESET  720   a  in symbols  708  indexed 1-2, a CORESET  702   b  in symbols 8-9. The CORESET  720   a  may be associated with the SSB  610   a  (with SSB index 0) of  FIG. 6 , and the CORESET  720   b  may be associated with the next SSB  610   b  (with SSB index 1) of  FIG. 6 . 
     As described above, the CORESET 0 may be used for carrying a PDCCH type 0 where RMSI scheduling information or SIB scheduling information (e.g., the RMSI scheduling information  322 ) may be transmitted. The BS  105  may configure a PDSCH (e.g., the PDSCH  330 ) for SIB transmission (e.g., the RMSI  332 ) in symbols  708  adjacent to and following a corresponding CORESET  720 . In this regard, the BS  105  may transmit SIB scheduling information associated with the SSB  610   a  in the CORESET  720   a,  where the SIB scheduling information may schedule a SIB  730   a  in a PDSCH located at symbols  708  indexed 3-6 subsequent to the CORESET  720   a.  The SIB  730   a  may occupy one or more of the symbols  708  indexed 3-6. Similarly, the BS  105  may transmit SIB scheduling information associated with the SSB  610   b  in the CORESET  720   b,  where the SIB scheduling information may schedule a SIB  730   b  in a PDSCH located at symbols  708  indexed 10-13 subsequent to the CORESET  720   b.  The SIB  730   b  may occupy one or more of the symbols  708  indexed 10-13. Symbols  708  indexed 0 and 7 in each slot  704  within the gap period  605  are gap symbols with no CORESET or SIB configured. The BS  105  may configure CORESETs and transmit SIBs for each remaining SSB of the group of SSBs  610  within the gap period  605 . Subsequently, the BS  105  may configure CORESETs and transmit SIBs for each remaining group of SSBs  620 ,  630 ,  640  in a gap period  605  after the respective group of SSBs  620 ,  630 ,  640  in a similar manner as shown by the expanded view  705 . 
     As an example, the SSB burst set may include 64 SSBs, for example, referred to as SSB 0 to SSB 63. Each SSB is associated with one of a set of 64 beams. The SSBs and associated CORESETs and SIBs may be scheduled or configured across time in the following order: a first group of 16 SSBs (e.g., SSB 0 to SSB 15), a first group of 16 CORESETs and 16 SIBs associated with the first group of 16 SSB, a second group of 16 SSBs (e.g., SSB 16 to SSB 31), a group of 16 CORESETs and 16 SIBs associated with the second group of 16 SSBs, a third group of 16 SSBs (e.g., SSB 32 to SSB 47), a group of 16 CORESETs and 16 SIBs associated with the third group of 16 SSB, and a fourth group of 16 SSBs (e.g., SSB 48 to SSB 63), a group of 16 CORESETs and 16 SIBs associated with the fourth group of 16 SSBs. 
     In some aspects, the time location of an SSB and the time location of a corresponding CORESET may have a relationship as shown below:

     and the starting symbols index for the CORESET are {0, 7, 0, 7} for i=4×k+{0, 1, 2, 3},
 
where SFN c  represents the system frame number identifying a radio frame (e.g., the radio frame  201 ) where the CORESET is located, SFN SSB  represents the system frame number identifying a radio frame (e.g., the radio frame  201 ) where the SSB is located, n c  represents the slot index, based on the second SCS, identifying a slot (e.g., the slot  704 ) where the CORESET is located within the radio frame, n i  represents the slot index, based on the second SCS, identifying a slot (e.g., the slot  604 ) where the SSB is located within the radio frame, and i represents the SSB index identifying the SSB, i mod 16 represents the reminder when i is divided by 16 and function floor(x) generates the largest integer that is equal to or smaller than x. In other words, the slot index for the slot  704  where the CORESET is located is dependent on the SSB index, the slot index for the slot where the SSB is located. The constant value 32 in equation (2) is related to the ratio (e.g., 4) between the first SCS  701  and the SCS  802 , a quantity of SSBs (e.g.,  16 ) in each group of SSBs  610 ,  620 ,  630 , and  640 , and a number of SSBs (e.g., 2) transmitted per slots  704 .
 
     In some aspects, the BS  105  may include an index in the SSB (e.g., in the MIB) pointing to a table with a single entry including the equation (2). In this way, the UE  115  may look up the table and compute the slot index for the CORESET using equation (2). In some implementations, the BS  105  may include a PDCCH-configSIB1 message structure in the SSB (e.g., in the MIB), where the PDCCH-configSIB1 message structure may include a table index field (e.g., an 8-bit field) providing one or more table lookup index for determining a CORESET configuration. Since, the scheme  700 A utilizes equation (2) to compute the CORESET slot index, at least some of the bits in the table index field may be repurposed for other indications. 
     A UE  115  may monitor for SSBs, for example, during an initial network access. Upon receiving an SSB (with an SSB index i) having a received quality (e.g., RSRP) satisfying a certain threshold, the UE  115  may determine not to monitor for further SSBs. The UE  115  identify a CORESET based on the received SSB. In this regard, the BS  105  may obtain an SSB index from the received SSB and identify a slot index of a slot where the SSB is received. The UE  115  may compute a slot index for the CORESET using equation (2) discussed above. In some instances, the UE  115  may obtain the equation (2) by looking up a preconfigured table based on a table index included in the SSB. 
       FIG. 7B  illustrates a system information multiplexing scheme  700 B according to some aspects of the present disclosure. The scheme  700 B may be employed by BSs such as the BSs  105  and UEs such as the UEs  115  in a network such as the network  100  for communications. In particular, the BS  105  may multiplex SSBs (e.g., the SSBs  310 ) transmitted based on a first SCS  701  (e.g., 120 kHz) with CORESET 0 (e.g., the CORESET  320 ) and SIBs (e.g., the RMSI  332 ) configured or scheduled based on a second SCS  702  (e.g., 480 kHz) as shown in the scheme  700 B. In  FIG. 7B , the x-axis represents time in some arbitrary units. The scheme  700 B is substantially similar to the scheme  700 A and may use the same reference numerals as in  FIG. 7A  for simplicity&#39;s sake. For instance, the BS  105  may configure a group of CORESETs and SIBs associated with a group of SSBs in a gap period  605  after the group of SSBs, and may determine a slot location for CORESETs and SIBs using the same equation (2) as discussed above. However, the BS  105  may configure the CORESETs and SIBs associated with the group of SSBs  620  within the gap periods  605  using different symbols compared to the scheme  700 B. 
     As shown by the expanded view  707 , the BS  105  configures a CORESET  720   a  in symbols  708  indexed 0-1, a CORESET  702   b  in symbols 7-8. The CORESET  720   a  may be associated with the SSB  610   a  (with SSB index 0) of  FIG. 6 , and the CORESET  720   b  may be associated with the next SSB  610   b  (with SSB index 1) of  FIG. 6 . 
     The BS  105  may further configure a PDSCH (e.g., the PDSCH  330 ) for SIB transmission (e.g., the RMSI  332 ) in symbols  708  adjacent to and following a corresponding CORESET  720 . For instance, the BS  105  may transmit SIB scheduling information associated with the SSB  610   a  in the CORESET  720   a,  where the SIB scheduling information may schedule a SIB  730   a  in a PDSCH located at symbols  708  indexed 2-5 subsequent to the CORESET  720   a.  The SIB  730   a  may occupy one or more of the symbols  708  indexed 2-5. Similarly, the BS  105  may transmit SIB scheduling information associated with the SSB  610   b  in the CORESET  720   b,  where the SIB scheduling information may schedule a SIB  730   b  in a PDSCH located at symbols  708  indexed 9-12 subsequent to the CORESET  720   b.  The SIB  730   b  may occupy one or more of the symbols  708  indexed 9-12. Symbols  708  indexed 6 and 13 in each slot  704  within the gap period  605  are gap symbols with no CORESET or SIB configured. The BS  105  may configure CORESETs and transmit SIBs for each remaining SSB of the group of SSBs  610  within the gap period  605 . Subsequently, the BS  105  may configure CORESETs and transmit SIBs for each remaining group of SSBs  620 ,  630 ,  640  in a gap period  605  after the respective group of SSBs  620 ,  630 ,  640  in a similar manner as shown by the expanded view  707 . 
     As can be observed, the multiplexing configuration in schemes  700 A and  700 B may enable a UE  115  to efficiently determine a slot location of a CORESET 0 based on a detected SSB without performing a complex table look up. Further, the multiplexing configuration can provide opportunities for a UE  115  to save power. For instance, the UE  115  may compute a slot location (e.g., n c ) where a CORESET 0 associated with the SSB is located and operate in a sleep mode until a time closer to the start of the slot including the CORESET 0. In this regard, the UE  115  may configure at least some RF components or modules and/or some baseband components or modules to operate at a lower power mode (sleep state). The UE  115  may wake up from the sleep mode, for example, at a time before the slot including the CORESET 0, and monitor for SIB scheduling information in the CORESET 0. 
       FIG. 8A  illustrates a system information multiplexing scheme  800 A according to some aspects of the present disclosure. The scheme  800 A may be employed by BSs such as the BSs  105  and UEs such as the UEs  115  in a network such as the network  100  for communications. In particular, the BS  105  may multiplex SSBs (e.g., the SSBs  310 ) transmitted based on a first SCS  701  (e.g.,  120  kHz) with corresponding CORESET 0 (e.g., the CORESET  320 ) configured based on a second SCS  802  (e.g., 960 kHz) as shown in the scheme  800 A. In  FIG. 8A , the x-axis represents time in some arbitrary units. The scheme  800 A is described using the same SSB transmission structure as in the scheme  600  and may use the same reference numerals as in  FIG. 6  for simplicity&#39;s sake. The scheme  800 A may use substantially similar mechanisms for scheduling CORESETs 0 and SIBs for corresponding SSBs, but the BS  105  may configure one CORESET in each slot  804  at the second SCS  802 . 
     As shown by the expanded view  803 , a gap period  605  including two slots  604  at the first SCS  701  of 120 kHz may include sixteen slots  804  (each with  14  symbols  808 ) at the second SCS  802  of 960 kHz. In other words, if the slots  804  are indexed beginning at index 0 (at the start of time period  602 ), the sixteen slots  804  may correspond to slots 64 to 79 at the second SCS  802  of 960 kHz. The BS  105  may configure one CORESETs (CORESET 0) in each slot  804 . With sixteen slots  804  in each gap period  605 , the BS  105  may configure 16 CORESETs in each gap period  605 . Each CORESET may correspond to one of the SSBs in a group of SSBs transmitted in preceding slots  604 . More specifically, the BS  105  may configure the CORESETs in the same sequential order across the gap period  605  as the SSBs. For instance, the BS  105  may configure a first CORESET for an SSB with an SSB index 0, followed by a second CORESET for an SSB with an SSB index 1, followed by a third CORESET for an SSB with an SSB index 2, and so on in a timeline across the gap period  605 . 
     In the expanded view  805 , symbols  808  in the first slot  804   a  of the gap period  605  are indexed from 0 to 13. Similarly, symbols  808  in the second slot  804   b  of the gap period  605  are indexed from 0 to 13. In the example illustrated in  FIG. 8A , the BS  105  configures a CORESET  820   a  in symbols  808  indexed 1-2 of the first slot  804   a  and configures a CORESET  820   b  in symbols indexed 1-2 of the second slot  804   b.  The CORESET  820   a  may be associated with the SSB  610   a  (with SSB index 0) of  FIG. 6 , and the CORESET  820   b  may be associated with the next SSB  610   b  (with SSB index 1) of  FIG. 6 . 
     As described above, the CORESET 0 may be used for carrying a PDCCH type 0 where RMSI scheduling information or SIB scheduling information (e.g., the RMSI scheduling information  322 ) may be transmitted. The BS  105  may configure a PDSCH (e.g., the PDSCH  330 ) for SIB transmission (e.g., the RMSI  332 ) in symbols  808  adjacent to and following a corresponding CORESET  820 . In this regard, the BS  105  may transmit SIB scheduling information associated with the SSB  610   a  in the CORESET  820   a,  where the SIB scheduling information may schedule a SIB  830   a  in a PDSCH located at symbols  808  indexed 3-13 subsequent to the CORESET  820   a  in the first slot  804   a.  The SIB  830   a  may occupy one or more of the symbols  808  indexed 3-13. Similarly, the BS  105  may transmit SIB scheduling information associated with the SSB  610   b  in the CORESET  820   b,  where the SIB scheduling information may schedule a SIB  830   b  in a PDSCH located at symbols  808  indexed 3-13 subsequent to the CORESET  820   b  in the second slot  804   b.  The SIB  830   b  may occupy one or more of the symbols  808  indexed 3-13 of the second slot  804   b.  Symbols  808  indexed 0 in each slot  804  within the gap period  605  is a gap symbol with no CORESET or SIB configured. The BS  105  may configure CORESETs and transmit SIBs for each remaining SSB of the group of SSBs  610  within the gap period  605 . Subsequently, the BS  105  may configure CORESETs and transmit SIBs for each remaining group of SSBs  620 ,  630 ,  640  in a gap period  605  after the respective group of SSBs  620 ,  630 ,  640  in a similar manner as shown by the expanded view  805 . 
     As an example, the SSB burst set may include 64 SSBs, for example, referred to as SSB 0 to SSB 63. Each SSB is associated with one of a set of 64 beams. The SSBs and associated CORESETs and SIBs may be scheduled or configured across time in the following order: a first group of 16 SSBs (e.g., SSB 0 to SSB 15), a first group of 16 CORESETs and 16 SIBs associated with the first group of 16 SSB, a second group of 16 SSBs (e.g., SSB 16 to SSB 31), a group of 16 CORESETs and 16 SIBs associated with the second group of 16 SSBs, a third group of 16 SSBs (e.g., SSB 32 to SSB 47), a group of 16 CORESETs and 16 SIBs associated with the third group of 16 SSB, and a fourth group of 16 SSBs (e.g., SSB 48 to SSB 63), a group of 16 CORESETs and 16 SIBs associated with the fourth group of 16 SSBs. 
     In some aspects, the time location of an SSB and the time location of a corresponding CORESET may have a relationship as shown below:

     and the starting symbols index for the CORESET are {0, 0, 0, 0} for i=4×k+{0, 1, 2, 3},
 
where SFN c  represents the system frame number identifying a radio frame (e.g., the radio frame  201 ) where the CORESET is located, SFN SSB  represents the system frame number identifying a radio frame (e.g., the radio frame  201 ) where the SSB is located, n c  represents the slot index identifying a slot (e.g., the slot  704 ) where the CORESET is located within the radio frame, n i  represents the slot index identifying a slot (e.g., the slot  604 ) where the SSB is located within the radio frame, and i represents the SSB index identifying the SSB, i mod 16 represents the reminder when i is divided by 16 and function floor(x) generates the largest integer that is equal to or smaller than x. In other words, the slot index for the slot  704  where the CORESET is located is dependent on the SSB index, the slot index for the slot where the SSB is located. The constant value 64 in equation (3) is related to the ratio (e.g., 8) between the first SCS  701  and the SCS  802 , a quantity of SSBs (e.g., 16) in each group of SSBs  610 ,  620 ,  630 , and  640 , and a number of SSBs (e.g., 2) transmitted per slots  804 .
 
     In some aspects, the BS  105  may include an index in the SSB (e.g., in the MIB) pointing to a table with a single entry including the equation (3). In this way, the UE  115  may look up the table and compute the slot index for the CORESET using equation (3). In some implementations, the BS  105  may include a PDCCH-configSIB1 message structure in the SSB (e.g., in the MIB), where the PDCCH-configSIB1 message structure may include a table index field (e.g., an 8-bit field) providing one or more table lookup index for determining a CORESET configuration. Since, the scheme  800 A utilizes equation (3) to compute the CORESET slot index, at least some of the bits in the table index field may be repurposed for other indications. 
     A UE  115  may monitor for SSBs, for example, during an initial network access. Upon receiving an SSB (with an SSB index i) having a received quality (e.g., RSRP) satisfying a certain threshold, the UE  115  may determine not to monitor for further SSBs. The UE  115  identify a CORESET based on the received SSB. In this regard, the BS  105  may obtain an SSB index from the received SSB and identify a slot index of a slot where the SSB is received. The UE  115  may compute a slot index for the CORESET using equation (3) discussed above. In some instances, the UE  115  may obtain the equation (3) by looking up a preconfigured table based on a table index included in the SSB. 
       FIG. 8B  illustrates a system information multiplexing scheme  800 B according to some aspects of the present disclosure. The scheme  800 B may be employed by BSs such as the BSs  105  and UEs such as the UEs  115  in a network such as the network  100  for communications. In particular, the BS  105  may multiplex SSBs (e.g., the SSBs  310 ) transmitted based on a first SCS  701  (e.g., 120 kHz) with CORESET 0 (e.g., the CORESET  320 ) and SIBs (e.g., the RMSI  332 ) configured or scheduled based on a second SCS  702  (e.g., 960 kHz) as shown in the scheme  800 B. In  FIG. 8B , the x-axis represents time in some arbitrary units. The scheme  800 B is substantially similar to the scheme  800 A and may use the same reference numerals as in  FIG. 8A  for simplicity&#39;s sake. For instance, the BS  105  may configure a group of CORESETs and SIBs associated with a group of SSBs in a gap period  605  after the group of SSBs, and may determine a slot location for CORESETs and SIBs using the same equation (3) as discussed above. However, the BS  105  may configure the CORESETs and SIBs associated with the group of SSBs  620  within the gap periods  605  using different symbols compared to the scheme  800 B. 
     As shown by the expanded view  807 , the BS  105  configures a CORESET  820   a  in symbols  808  indexed 0-1 of the first slot  804   a  and configures a CORESET  820   b  in symbols indexed 0-1 of the second slot  804   b.  The CORESET  820   a  may be associated with the SSB  610   a  (with SSB index 0) of  FIG. 6 , and the CORESET  820   b  may be associated with the next SSB  610   b  (with SSB index 1) of  FIG. 6 . 
     The BS  105  may further configure a PDSCH (e.g., the PDSCH  330 ) for SIB transmission (e.g., the RMSI  332 ) in symbols  808  adjacent to and following a corresponding CORESET  820 . For instance, the BS  105  may transmit SIB scheduling information associated with the SSB  610   a  in the CORESET  820   a,  where the SIB scheduling information may schedule a SIB  830   a  in a PDSCH located at symbols  808  indexed 2-12 subsequent to the CORESET  820   a  in the first slot  804   a.  The SIB  830   a  may occupy one or more of the symbols  808  indexed 2-12 of the slot  804   a.  Similarly, the BS  105  may transmit SIB scheduling information associated with the SSB  610   b  in the CORESET  820   b,  where the SIB scheduling information may schedule a SIB  830   b  in a PDSCH located at symbols  808  indexed 2-12 subsequent to the CORESET  820   b  in the second slot  804   b.  The SIB  830   b  may occupy one or more of the symbols  808  indexed 2-12 of the slot  804   b.  Symbols  808  indexed 13 in each slot  804  within the gap period  605  is a gap symbol with no CORESET or SIB configured. The BS  105  may configure CORESETs and transmit SIBs for each remaining SSB of the group of SSBs  610  within the gap period  605 . Subsequently, the BS  105  may configure CORESETs and transmit SIBs for each remaining group of SSBs  620 ,  630 ,  640  in a gap period  605  after the respective group of SSBs  620 ,  630 ,  640  in a similar manner as shown by the expanded view  805 . 
     In some aspects, similar to the schemes  700 A- 700 B, the multiplexing configuration in schemes  800 A- 800 B may also enable a UE  115  to efficiently determine a slot location of a CORESET 0 based on a detected SSB without performing a complex table look up. Further, the multiplexing configuration can provide opportunities for a UE  115  to save power as discussed above with reference to  FIGS. 7A-7B . 
     In some aspects, the BS  105  may employ the scheme  700 A,  700 B,  800 A, or  800 B to define time locations (e.g., fixed time locations) for SSB/CORESET 0/RMSI scheduling and/or transmission using a set of predefined beam directions (e.g., using 64 different beams), but may not transmit SSBs using all 64 beams. In other words, some of the symbols (e.g., the symbols  608  of  FIG. 6 ) or slots  604  configured for SSB transmission may be unoccupied. When employing the scheme  700 A,  700 B,  800 A, or  800 B with a fixed multiplexing configuration, the BS  105  may not schedule CORESET 0 and/or SIBs in those unoccupied slots. 
       FIG. 9  is a sequence diagram illustrating a communication method  900  for initial network access according to some aspects of the present disclosure. The method  900  may be performed by a wireless network, such as the network  100 . In this regard, the method  900  is performed by a BS  105  and a UE  115 . In some aspects, the BS  105  and the UE  115  may communicate with each other over a high-frequency band, such as a mmWave band, and may apply beamforming techniques to form directional beams for transmission and/or receptions. The method  900  may employ similar mechanisms as discussed above with reference to  FIGS. 6-8 . In some aspects, the BS  105  may utilize one or more components, such as the processor  1002 , the memory  1004 , the system information module  1008 , the transceiver  1010 , the modem  1012 , and the one or more antennas  1016  shown in  FIG. 10 , to execute the actions of the method  900 . The UE  115  may utilize one or more components, such as the processor  1102 , the memory  1104 , the system information module  1108 , the transceiver  1110 , the modem  1112 , and the one or more antennas  1116  shown in  FIG. 11 , to execute the actions of the method  900 . As illustrated, the method  900  includes a number of enumerated action, but aspects of the method  900  may include additional actions before, after, and in between the enumerated actions. In some aspects, one or more of the enumerated actions may be omitted or performed in a different order. 
     In the method  900 , a BS  105  may transmit SSB in an SSB burst set in groups spaced apart from each other in time by gap periods, and may configure and/or schedule CORESETs 0 and SIBs associated with the SSBs during the gap periods. As shown, at action  910 , the BS  105  transmits a first SSB (e.g., the SSB  610   a ) of a first group of SSBs (e.g., the group of SSBs  610 ) in the SSB burst set. The first SSB may be associated with an SSB index 0. For example, the first SSB may include an indication of an SSB index 0. The SSB burst set may be associated with a set of predefined beam directions, and the BS  105  may transmit the first SSB in a first beam direction of the set of predefined beam directions. 
     At action  912 , the BS  105  transmits a second SSB (e.g., the SSB  610   b ) of the first group of SSBs. The second SSB may be associated with an SSB index 1. For example, the first SSB may include an indication of an SSB index 1. The BS  105  may transmit the second SSB in a next beam direction (e.g., a second beam direction) of the set of beam directions. 
     The BS  105  may transmit all SSBs in the first group of SSBs, for example, with each SSB in a different beam direction according the set of predefined beam directions. For instance, at action  914 , the BS  105  may transmit a last SSB (e.g., K th  SSB) of the first group of SSBs. The K th  SSB may be associated with an SSB index K−1. For example, the first SSB may include an indication of an SSB index K−1. The BS  105  may transmit the K th  SSB in a K th  beam direction in the set of beam directions. 
     In some aspects, the BS  105  may transmit the first group of SSBs (at actions  910 - 914 ) in a first set of consecutive slots, where every four SSBs are transmitted in one of the first set of consecutive slots as discussed above with reference to  FIG. 6 . Accordingly, the BS  105  may determine a starting symbol location for each SSB in the first group of SSBs in accordance with the equation (1) described above. In some aspects, the first set of consecutive slots carrying the first group of SSBs may be spaced apart from a second set of consecutive slots configured for carrying a second group of SSBs of the SSB burst set. The first set of consecutive slots and the second set of consecutive slots may be spaced by a gap period (e.g., the gap period  605 ). The gap period may include resources configured and/or scheduled for a first group of CORESETs and SSBs that is associated with the first group of SSBs. 
     For instance, at action  920 , the BS  105  determines CORESETs for the first group of SSBs. In this regard, the BS  105  may determine a CORESET (e.g., CORESET 0) for each SSB of the first group of SSBs. The BS  105  may compute a slot location of the CORESET based on a slot location of a respective SSB. In some aspects, the BS  105  may transmit the first group of SSBs based on a first SCS and may configure CORESETs 0 in resources (within the gap period) defined based on a second SCS. In some aspects, the first SCS is 120 kHz and the second SCS is 480 kHz as discussed above with reference to  FIGS. 7A-7B . Accordingly, the BS  105  may determine a slot location for the CORESET in accordance with the equation (2) described above. In some other aspects, the first SCS is 120 kHz and the second SCS is 960 kHz as discussed above with reference to  FIGS. 8A-8B . Accordingly, the BS  105  may determine a slot location for the CORESET in accordance with the equation (3) described above. 
     At action  930 , after transmitting the first group of SSBs, the BS  105  transmits first SIB scheduling information (e.g., the RMSI scheduling information  322 ) in a first CORESET (e.g., the CORESET  720   a  or  820   a ) of the determined CORESETs. The first SIB scheduling information is associated with the first SSB and the BS  105  may transmit the first SIB scheduling information in the same first beam direction as the first SSB. The first SIB scheduling information may indicate resources in a PDSCH (e.g., the PDSCH  330 ). 
     At action  932 , the BS  105  transmits a first SIB (e.g., the SIB  730   a  or  830   a ) according to the first SIB scheduling information. In this regard, the BS  105  may transmit the first SIB in the resources indicated by the first SIB scheduling information. The BS  105  may also utilize MCS and/or other transmission parameters indicated by the first SIB scheduling information to transmit the first SIB. In some aspects, the second SCS is 480 kHz, and the BS  105  may schedule and/or configure the first CORESET and the first SIB as discussed above with reference to  FIG. 7A  (e.g., as shown in the expanded view  705 ) or  FIG. 7B  (e.g., as shown in the expanded view  707 ). In some other aspects, the second SCS is 960 kHz, and the BS  105  may schedule and/or configure the first CORESET and the first SIB as discussed above with reference to  FIG. 8A  (e.g., as shown in the expanded view  805 ) or  FIG. 8B  (e.g., as shown in the expanded view  807 ). The first SIB is associated with the first SSB and the BS  105  may transmit the first SIB in the same first beam direction as the first SSB. 
     At action  934 , the BS  105  transmits second SIB scheduling information (e.g., the RMSI scheduling information  322 ) in a second CORESET (e.g., the CORESET  720   b  or  820   b ) of the determined CORESETs. The second SIB scheduling information is associated with the second SSB and the BS  105  may transmit the second SIB scheduling information in the same second beam direction as the second SSB. The second SIB scheduling information may indicate resources in a PDSCH (e.g., the PDSCH  330 ). 
     At action  936 , the BS  105  transmits a second SIB (e.g., the SIB  730   b  or  830   b ) according to the second SIB scheduling information. In this regard, the BS  105  may transmit the second SIB in the resources indicated by the second SIB scheduling information. The BS  105  may also utilize MCS and/or other transmission parameters indicated by the second SIB scheduling information to transmit the second SIB. In some aspects, the second SCS is 480 kHz, and the BS  105  may schedule and/or configure the second CORESET and second SIB as discussed above with reference to  FIG. 7A  (e.g., as shown in the expanded view  705 ) or  FIG. 7B  (e.g., as shown in the expanded view  707 ). In some other aspects, the second SCS is 960 kHz, and the BS  105  may schedule and/or configure the second CORESET and the second SIB as discussed above with reference to  FIG. 8A  (e.g., as shown in the expanded view  805 ) or  FIG. 8B  (e.g., as shown in the expanded view  807 ). The second SIB is associated with the second SSB and the BS  105  may transmit the second SIB in the same second beam direction as the second SSB. 
     The BS  105  may continue to transmit SIB scheduling information and SIBs for all SSBs in the first group of SSBs. For instance, at action  938 , the BS  105  may transmit last SIB scheduling information (e.g., K th  SIB scheduling information) of the first group of SSBs. The K th  SIB scheduling information is associated with the K th  SSB and the BS  105  may transmit the K th  SIB scheduling information in the same K th  beam direction as the K th  SSB. The K th  SIB scheduling information may indicate resources in a PDSCH (e.g., the PDSCH  330 ). 
     At action  940 , the BS  105  transmits a K th  SIB (e.g., the SIB  730   b  or  830   b ) according to the K th  SIB scheduling information. In this regard, the BS  105  may transmit the K th  SIB in the resources indicated by the K th  SIB scheduling information. The BS  105  may also utilize MCS and/or other transmission parameters indicated by the K th  SIB scheduling information to transmit the second SIB. In some aspects, the second SCS is 480 kHz, and the BS  105  may schedule and/or configure the K th  CORESET and the K th  SIB as discussed above with reference to  FIG. 7A  (e.g., as shown in the expanded view  705 ) or  FIG. 7B  (e.g., as shown in the expanded view  707 ). In some other aspects, the second SCS is 960 kHz, and the BS  105  may schedule and/or configure the K th  CORESET and the K th  SIB as discussed above with reference to  FIG. 8A  (e.g., as shown in the expanded view  805 ) or  FIG. 8B  (e.g., as shown in the expanded view  807 ). The K th  SIB is associated with the K th  SSB and the BS  105  may transmit the K th  SIB in the same K th  beam direction as the K th  SSB. 
     At action  950 , the UE  115  may monitor for SSBs from the BS  105 , for example, based on the first SCS. In some instances, the UE  115  may sweep through one or more beam directions in a set of predefined beam directions to monitor for the SSBs. The UE  115  may determine a received signal measurement (e.g., RSRP) for each detected SSB and may determine whether the received signal measurement satisfies a predetermined threshold. The UE  115  may determine an optimal beam direction for communicating with the BS  105 . As an example, the UE  115  may determine that the second SSB in the second beam direction (transmitted by the BS  105  at action  912 ) provides a best received quality (e.g., highest RSRP) among detected SSBs or at least provides a received quality satisfying a certain threshold. 
     At action  960 , the UE  115  identifies a CORESET based on the second SSB. In some aspects, the second SCS is 480 kHz, and the second the UE  115  may determine a slot location for the CORESET in accordance with the equation (2) discussed above with reference to  FIGS. 7A-7B . In some aspects, the second SCS is 960 kHz, and the second the UE  115  may determine a slot location for the CORESET in accordance with the equation (3) discussed above with reference to  FIGS. 8A-8B . The CORESET may correspond to the second CORESET. 
     At action  970 , the UE  115  monitors for SIB scheduling information in second CORESET based on the second SCS. The UE  115  may receive the second SIB scheduling information (transmitted by the BS  105  at action  934 ). 
     At action  980 , upon receiving the second SIB scheduling information, the UE  115  receives the second SIB according to the second SIB scheduling information. 
     Subsequently, the BS  105  may transmit the second group of SSBs using similar operations as at actions  910  to  914 , followed by SIB scheduling information and SIBs associated with the second group of SSBs using similar operations as at actions  930  to  940 . The BS  105  may continue until all groups of SSBs (of the SSB burst set) and associated SIB scheduling information SIBs are transmitted. The BS  105  may repeat the transmission of the SSB burst set and associated SIB scheduling information SIBs according to a certain periodicity (e.g., about 20 ms, 40 ms, 80 ms, or 160 ms). In some other aspects, the BS  105  may not transmit all SSBs in the SSB burst set, but may still schedule and/or configure associated CORESETs and SIBs in the same symbols within the same gap periods as when all SSBs are transmitted. 
       FIG. 10  is a block diagram of an exemplary BS  1000  according to some aspects of the present disclosure. The BS  1000  may be a BS  105  in the network  100  as discussed above in  FIG. 1 . A shown, the BS  1000  may include a processor  1002 , a memory  1004 , a system information module  1008 , a transceiver  1010  including a modem subsystem  1012  and a RF unit  1014 , and one or more antennas  1016 . These elements may be coupled with one another. The term “coupled” may refer to directly or indirectly coupled or connected to one or more intervening elements. For instance, these elements may be in direct or indirect communication with each other, for example via one or more buses. 
     The processor  1002  may have various features as a specific-type processor. For example, these may include a CPU, a DSP, an ASIC, a controller, a FPGA device, another hardware device, a firmware device, or any combination thereof configured to perform the operations described herein. The processor  1002  may also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration. 
     The memory  1004  may include a cache memory (e.g., a cache memory of the processor  1002 ), RAM, MRAM, ROM, PROM, EPROM, EEPROM, flash memory, a solid state memory device, one or more hard disk drives, memristor-based arrays, other forms of volatile and non-volatile memory, or a combination of different types of memory. In some aspects, the memory  1004  may include a non-transitory computer-readable medium. The memory  1004  may store instructions  1006 . The instructions  1006  may include instructions that, when executed by the processor  1002 , cause the processor  1002  to perform operations described herein, for example, aspects of  FIGS. 1-2 and 6-9 , and  13 . Instructions  1006  may also be referred to as program code. The program code may be for causing a wireless communication device to perform these operations, for example by causing one or more processors (such as processor  1002 ) to control or command the wireless communication device to do so. The terms “instructions” and “code” should be interpreted broadly to include any type of computer-readable statement(s). For example, the terms “instructions” and “code” may refer to one or more programs, routines, sub-routines, functions, procedures, etc. “Instructions” and “code” may include a single computer-readable statement or many computer-readable statements. 
     The system information module  1008  may be implemented via hardware, software, or combinations thereof. For example, the system information module  1008  may be implemented as a processor, circuit, and/or instructions  1006  stored in the memory  1004  and executed by the processor  1002 . In some examples, the system information module  1008  can be integrated within the modem subsystem  1012 . For example, the system information module  1008  can be implemented by a combination of software components (e.g., executed by a DSP or a general processor) and hardware components (e.g., logic gates and circuitry) within the modem subsystem  1012 . 
     The system information module  1008  may communicate with various components of the BS  1000  to perform various aspects of the present disclosure, for example, aspects of FIGS.  FIGS. 1-2 and 6-9, and 13 . The system information module  1008  is configured to transmit a first group of SSBs and a second group of SSBs of an SSB burst set. In some instances, the SSB burst set may be associated with a set of predefined beam directions. The first group of SSBs and the second group of SSBs are spaced apart in time by resources associated with a group of CORESETs and SIBs. The group of CORESETs and SIBs includes one CORESET and at least one SIB for each SSB of the first group of SSBs. 
     In some aspects, the group of CORESETs and SIBs are associated with the first group of SSBs and are located in a gap period after the first group of SSBs (e.g., as shown in  FIGS. 7A-7B and 8A-8B ). In other aspects, the group of CORESETs and SIBs are associated with the first group of SSBs and are located in a gap period before the first group of SSBs (e.g., as shown in  FIGS. 14A-14B and 15A-15B ). 
     In some aspects, the first group of SSBs and the second group of SSBs are associated with a first SCS, and the group of CORESETs and SIBs is associated with a second SCS.

In particular, the BS  105  may multiplex SSBs (e.g., the SSBs  310 ) transmitted based on a first SCS  701  (e.g., 120 kHz) with CORESET 0 (e.g., the CORESET  320 ) and SIBs (e.g., the RMSI  332 ) configured or scheduled based on a second SCS  702  (e.g., 480 kHz) as shown in the scheme  1400 . In  FIG. 14A and 14B , the x-axes represent time in some arbitrary units. The scheme  1400  is described using the same SSB transmission structure as in the scheme  600  and the same SCS configuration as in the schemes  700 A- 700 B, and may use the same reference numerals as in  FIGS. 6 and 7A-7B  for simplicity&#39;s sake. 
     As described above, the BS  105  may time-multiplex SSBs and associated CORESETs (CORESET 0) in units of SSB groups and CORESET/SIB groups. In contrast to the schemes  700 A and  700 B, the BS  105  configures and/or schedules a group of CORESETs and SIBs for a group of SSBs within the same set of consecutive slots where the group of SSBs is transmitted (using gap period or gap symbols within the set of consecutive slots).

The SIB  730   a  may occupy one or more of the symbols  1408  indexed 2-5. Similarly, the BS  105  may transmit SIB scheduling information associated with the SSB  610   b  in the CORESET  720   b,  where the SIB scheduling information may schedule a SIB  730   b  in a PDSCH located at symbols  1408  indexed 9-12 subsequent to the CORESET  720   b.

The BS  105  may configure a CORESET  720   c  for the SSB  610   c  in the symbols  1408  indexed 49-50 and may configure a CORESET  720   d  for the SSB  610   d  in the symbols  1408  indexed 56-57. The CORESET  720   c  and the CORESET  720   d  are aligned to slot/mini-slot boundaries. The BS  105  may configure a PDSCH (e.g., the PDSCH  330 ) for SIB transmission (e.g., the RMSI  332 ) in symbols  1408  adjacent to and following a corresponding CORESET  720 . In this regard, the BS  105  may transmit SIB scheduling information associated with the SSB  610   c  in the CORESET  720   c,  where the SIB scheduling information may schedule a SIB  730   c  in a PDSCH located at symbols  1408  indexed 51-54 subsequent to the CORESET  720   c.

The SIB  730   d  may occupy one or more of the symbols  1408  indexed 58-61. 
     The BS  105  may configure CORESETs and transmit SIBs for each remaining SSB in the group of SSBs  610 ,  620 ,  630 ,  640  in a similar manner as shown by the expanded view  1403  of  FIG. 14A  and/or the expanded view  1407  of  FIG. 14B . In general, the slot time location of an SSB and the time location of a corresponding CORESET may have a relationship as shown below:

     and the starting symbols index for the CORESET are {0, 7, 7, 0} for i=4×k+{0, 1, 2, 3}, and i represents the SSB index and slot index n c  is based on the second SCS. 
       FIG. 15A-15B  illustrates a system information multiplexing scheme  1500  according to some aspects of the present disclosure. The scheme  1500  may be employed by BSs such as the BSs  105  and UEs such as the UEs  115  in a network such as the network  100  for communications. In particular, the BS  105  may multiplex SSBs (e.g., the SSBs  310 ) transmitted based on a first SCS  701  (e.g., 120 kHz) with CORESET 0 (e.g., the CORESET  320 ) and SIBs (e.g., the RMSI  332 ) configured or scheduled based on a second SCS  802  (e.g., 960 kHz) as shown in the scheme  1500 . In  FIG. 15A and 15B , the x-axes represent time in some arbitrary units. The scheme  1500  is described using the same SSB transmission structure as in the scheme  600  and the same SCS configuration as in the scheme  800 A- 800 B, and may use the same reference numerals as in  FIGS. 6 and 8A-8B  for simplicity&#39;s sake. 
     As described above, the BS  105  may time-multiplex SSBs and associated CORESETs (CORESET 0) in units of SSB groups and CORESET/SIB groups. In contrast to the schemes  800 A and  800 B, the BS  105  configures and/or schedules a group of CORESETs and SIBs for a group of SSBs within the same set of consecutive slots where the group of SSBs is transmitted (using gap period or gap symbols within the set of consecutive slots). 
       FIG. 15A and 15B  illustrate the same expanded views  601  and  603  of  FIG. 6 . As can be seen in the expanded view  603 , symbols  608  indexed 0-3 before the SSBs  610   a  and  610   b  are unoccupied (a gap period  1405  shown by the empty-filled boxes). Similarly, symbols  608  indexed 12-15 before the SSBs  610   c  and  610   d  are unoccupied (a gap period  1405  shown the empty-filled boxes). In the scheme  1500 , the BS  105  may configure and/or schedule a group of CORESETs/SIBs for every sub-group of two SSBs in a gap period  1405  (shown as  1405   a  and  1405   b ) before the sub-group of two SSBs. For instance, the BS  105  may configure and/or schedule a group of CORESETs/SIBs for the two SSBs  610   a  and  610   b  in the symbols  608  indexed 0-3, and may configure and/or schedule a group of CORESETs/SIBs for the two SSBs  610   c  and  610   d  in the symbols  608  indexed 12-15. 
     A gap period  1405  including four symbols  608  at the first SCS  701  of 120 kHz may include thirty-two symbols  1408  at the second SCS  802  of 960 kHz. Referring to  FIG. 15A , in the expanded view  1503 , the symbols  1508  in the gap period  1405   a  are indexed from 0 to 31, and the vertical dashed lines at the start of symbols  1508  indexed 0, 14, and 28 are slot boundaries. The BS  105  may configure a CORESET  820   a  for the SSB  610   a  in the symbols  1508  indexed 0-1 and may configure a CORESET  820   b  for the SSB  610   b  in the symbols  1408  indexed 14-15. The CORESET  820   a  and the CORESET  820   b  are aligned to the mini-slot boundaries. The BS  105  may configure a PDSCH (e.g., the PDSCH  330 ) for SIB transmission (e.g., the RMSI  332 ) in symbols  1508  adjacent to and following a corresponding CORESET  820 . In this regard, the BS  105  may transmit SIB scheduling information associated with the SSB  610   a  in the CORESET  820   a,  where the SIB scheduling information may schedule a SIB  830   a  in a PDSCH located at symbols  1508  indexed 2-12 subsequent to the CORESET  820   a.  The SIB  830   a  may occupy one or more of the symbols  1508  indexed 2-12. Similarly, the BS  105  may transmit SIB scheduling information associated with the SSB  610   b  in the CORESET  820   b,  where the SIB scheduling information may schedule a SIB  830   b  in a PDSCH located at symbols  1508  indexed 16-26 subsequent to the CORESET  820   b.  The SIB  830   b  may occupy one or more of the symbols  1408  indexed 16-26. 
     Referring to  FIG. 15B , in the expanded view  1507 , the symbols  1508  in the gap period  1405   b  are indexed from 96 to 127, and the vertical dashed lines at the start of symbols  1508  indexed 98, 112, and 126 are slot boundaries. The BS  105  may configure a CORESET  820   c  for the SSB  610   c  in the symbols  1508  indexed 98-99 and may configure a CORESET  820   d  for the SSB  610   d  in the symbols  1508  indexed 112-113. The CORESET  820   c  and the CORESET  820   d  are aligned to slot boundaries. The BS  105  may configure a PDSCH (e.g., the PDSCH  330 ) for SIB transmission (e.g., the RMSI  332 ) in symbols  1508  adjacent to and following a corresponding CORESET  820 . In this regard, the BS  105  may transmit SIB scheduling information associated with the SSB  610   c  in the CORESET  820   c,  where the SIB scheduling information may schedule a SIB  830   c  in a PDSCH located at symbols  1508  indexed 100-110 subsequent to the CORESET  820   c.  The SIB  830   c  may occupy one or more of the symbols  1508  indexed 100-110. Similarly, the BS  105  may transmit SIB scheduling information associated with the SSB  610   d  in the CORESET  820   d,  where the SIB scheduling information may schedule a SIB  830   d  in a PDSCH located at symbols  1508  indexed 114-124 subsequent to the CORESET  820   d.  The SIB  830   d  may occupy one or more of the symbols  1508  indexed 114-124. 
     The BS  105  may configure CORESETs and transmit SIBs for each remaining SSB in the group of SSBs  610 ,  620 ,  630 ,  640  in a similar manner as shown by the expanded view  1503  of  FIG. 15A  and/or the expanded view  1507  of  FIG. 15B .
