CROSS-REFERENCE TO RELATED APPLICATION 
     This patent application claims priority to U.S. Provisional Patent Application No. 63/199,822, filed on Jan. 27, 2021, entitled “BEAM ALIGNMENT FOR TRANSMISSIONS USING DIFFERENT SUBCARRIER SPACINGS,” and assigned to the assignee hereof. The disclosure of the prior application is considered part of and is incorporated by reference into this patent application. 
    
    
     FIELD OF THE DISCLOSURE 
     Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for beam alignment for transmissions using different subcarrier spacings. 
     BACKGROUND 
     Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). 
     A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs). A UE may communicate with a BS via the downlink and uplink. “Downlink” (or “forward link”) refers to the communication link from the BS to the UE, and “uplink” (or “reverse link”) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a New Radio (NR) BS, a 5G Node B, or the like. 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. NR, which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

     DETAILED DESCRIPTION 
     Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. 
     Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
       FIG. 1  is a diagram illustrating an example of a wireless network  100 , in accordance with the present disclosure. The wireless network  100  may be or may include elements of a 5G (NR) network and/or an LTE network, among other examples. The wireless network  100  may include a number of base stations  110  (shown as BS  110   a , BS  110   b , BS  110   c , and BS  110   d ) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), or the like. A network entity may be a BS or may include one or more components of a BS, such as in a disaggregated radio access network (RAN) configuration or open RAN configuration. For example, a network entity may include an aggregated BS, one or more components of a disaggregated BS, a central unit (CU), a distributed unit (DU), a radio unit (RU), a repeater, a relay, a TRP, or an integrated access and backhaul (IAB) node, among other examples. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used. 
     A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG)). ABS for a macro cell may be referred to as a macro BS. ABS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in  FIG. 1 , a BS  110   a  may be a macro BS for a macro cell  102   a , a BS  110   b  may be a pico BS for a pico cell  102   b , and a BS  110   c  may be a femto BS for a femto cell  102   c . A BS may support one or multiple (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” may be used interchangeably herein. 
     In some aspects, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network. 
     Wireless network  100  may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in  FIG. 1 , a relay BS  110   d  may communicate with macro BS  110   a  and a UE  120   d  in order to facilitate communication between BS  110   a  and UE  120   d . A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like. 
     Wireless network  100  may be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network  100 . For example, macro BSs may have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts). 
     A network controller  130  may couple to a set of BSs and may provide coordination and control for these BSs. Network controller  130  may communicate with the BSs via a backhaul. The BSs may also communicate with one another, directly or indirectly, via a wireless or wireline backhaul. 
     UEs  120  (e.g.,  120   a ,  120   b ,  120   c ) may be dispersed throughout wireless network  100 , and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, or the like. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium. 
     Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and/or location tags, that may communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE). UE  120  may be included inside a housing that houses components of UE  120 , such as processor components and/or memory components. In some aspects, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled. 
     In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, or the like. A frequency may also be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed. 
     In some aspects, two or more UEs  120  (e.g., shown as UE  120   a  and UE  120   e ) may communicate directly using one or more sidelink channels (e.g., without using a base station  110  as an intermediary to communicate with one another). For example, the UEs  120  may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol or a vehicle-to-infrastructure (V2I) protocol), and/or a mesh network. In this case, the UE  120  may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station  110 . 
     Devices of wireless network  100  may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, channels, or the like. For example, devices of wireless network  100  may communicate using an operating band having a first frequency range (FR1), which may span from 410 MHz to 7.125 GHz, and/or may communicate using an operating band having a second frequency range (FR2), which may span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. Thus, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies within the EHF band, frequencies within FR2, and/or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and techniques described herein are applicable to those modified frequency ranges. 
     As indicated above,  FIG. 1  is provided as an example. Other examples may differ from what is described with regard to  FIG. 1 . 
       FIG. 2  is a diagram illustrating an example  200  of a base station  110  in communication with a UE  120  in a wireless network  100 , in accordance with the present disclosure. Base station  110  may be equipped with T antennas  234   a  through  234   t , and UE  120  may be equipped with R antennas  252   a  through  252   r , where in general T≥1 and R≥1. 
     At base station  110 , a transmit processor  220  may receive data from a data source  212  for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for the UE, and provide data symbols for all UEs. Transmit processor  220  may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor  220  may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor  230  may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs)  232   a  through  232   t . Each modulator  232  may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator  232  may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators  232   a  through  232   t  may be transmitted via T antennas  234   a  through  234   t , respectively. 
     At UE  120 , antennas  252   a  through  252   r  may receive the downlink signals from base station  110  and/or other base stations and may provide received signals to demodulators (DEMODs)  254   a  through  254   r , respectively. Each demodulator  254  may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator  254  may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector  256  may obtain received symbols from all R demodulators  254   a  through  254   r , perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor  258  may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE  120  to a data sink  260 , and provide decoded control information and system information to a controller/processor  280 . The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some aspects, one or more components of UE  120  may be included in a housing  284 . 
     Network controller  130  may include communication unit  294 , controller/processor  290 , and memory  292 . Network controller  130  may include, for example, one or more devices in a core network. Network controller  130  may communicate with base station  110  via communication unit  294 . 
     Antennas (e.g., antennas  234   a  through  234   t  and/or antennas  252   a  through  252   r ) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and/or antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include a set of coplanar antenna elements and/or a set of non-coplanar antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include antenna elements within a single housing and/or antenna elements within multiple housings. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of  FIG. 2 . 
     On the uplink, at UE  120 , a transmit processor  264  may receive and process data from a data source  262  and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from controller/processor  280 . Transmit processor  264  may also generate reference symbols for one or more reference signals. The symbols from transmit processor  264  may be precoded by a TX MIMO processor  266  if applicable, further processed by modulators  254   a  through  254   r  (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station  110 . In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD  254 ) of the UE  120  may be included in a modem of the UE  120 . In some aspects, the UE  120  includes a transceiver. The transceiver may include any combination of antenna(s)  252 , modulators and/or demodulators  254 , MIMO detector  256 , receive processor  258 , transmit processor  264 , and/or TX MIMO processor  266 . The transceiver may be used by a processor (e.g., controller/processor  280 ) and memory  282  to perform aspects of any of the methods described herein (for example, as described with reference to  FIGS. 8-14 ). 
     At base station  110 , the uplink signals from UE  120  and other UEs may be received by antennas  234 , processed by demodulators  232 , detected by a MIMO detector  236  if applicable, and further processed by a receive processor  238  to obtain decoded data and control information sent by UE  120 . Receive processor  238  may provide the decoded data to a data sink  239  and the decoded control information to controller/processor  240 . Base station  110  may include communication unit  244  and communicate to network controller  130  via communication unit  244 . Base station  110  may include a scheduler  246  to schedule UEs  120  for downlink and/or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD  232 ) of the base station  110  may be included in a modem of the base station  110 . In some aspects, the base station  110  includes a transceiver. The transceiver may include any combination of antenna(s)  234 , modulators and/or demodulators  232 , MIMO detector  236 , receive processor  238 , transmit processor  220 , and/or TX MIMO processor  230 . The transceiver may be used by a processor (e.g., controller/processor  240 ) and memory  242  to perform aspects of any of the methods described herein (for example, as described with reference to  FIGS. 8-14 ). 
     Controller/processor  240  of base station  110 , controller/processor  280  of UE  120 , and/or any other component(s) of  FIG. 2  may perform one or more techniques associated with beam alignment for transmissions using different subcarrier spacings (SCSs), as described in more detail elsewhere herein. For example, controller/processor  240  of base station  110 , controller/processor  280  of UE  120 , and/or any other component(s) of  FIG. 2  may perform or direct operations of, for example, process  1100  of  FIG. 11 , process  1200  of  FIG. 12 , and/or other processes as described herein. Memories  242  and  282  may store data and program codes for base station  110  and UE  120 , respectively. In some aspects, memory  242  and/or memory  282  may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station  110  and/or the UE  120 , may cause the one or more processors, the UE  120 , and/or the base station  110  to perform or direct operations of, for example, process  1100  of  FIG. 11 , process  1200  of  FIG. 12 , and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples. 
     In some aspects, the UE includes means for receiving, from a base station, one or more synchronization signal block (SSB) transmissions associated with a first SCS; and/or means for receiving, from the base station, one or more initial access transmissions associated with a second SCS. In some aspects, a time location of an initial access transmission, of the one or more initial access transmissions, that uses a beam is based at least in part on a time location of an SSB transmission, of the one or more SSB transmissions, that uses the beam. The means for the UE to perform operations described herein may include, for example, one or more of antenna  252 , demodulator  254 , MIMO detector  256 , receive processor  258 , transmit processor  264 , TX MIMO processor  266 , modulator  254 , controller/processor  280 , or memory  282 . 
     In some aspects, the base station includes means for transmitting, to a UE, one or more SSB transmissions associated with a first SCS; and/or means for transmitting, to the UE or another UE, one or more initial access transmissions associated with a second SCS. In some aspects, a time location of an initial access transmission, of the one or more initial access transmissions, that uses a beam is based at least in part on a time location of an SSB transmission, of the one or more SSB transmissions, that uses the beam. The means for the base station to perform operations described herein may include, for example, one or more of transmit processor  220 , TX MIMO processor  230 , modulator  232 , antenna  234 , demodulator  232 , MIMO detector  236 , receive processor  238 , controller/processor  240 , memory  242 , or scheduler  246 . 
     While blocks in  FIG. 2  are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor  264 , the receive processor  258 , and/or the TX MIMO processor  266  may be performed by or under the control of controller/processor  280 . 
     As indicated above,  FIG. 2  is provided as an example. Other examples may differ from what is described with regard to  FIG. 2 . 
       FIG. 3  is a diagram illustrating an example  300  of a frame structure in a wireless communication network, in accordance with the present disclosure. The frame structure shown in  FIG. 3  is for frequency division duplexing (FDD) in a telecommunication system, such as LTE or NR. The transmission timeline for each of the downlink and uplink may be partitioned into units of radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be partitioned into a set of Z (Z≥1) subframes (e.g., with indices of 0 through Z−1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of slots (e.g., 2m slots per subframe are shown in  FIG. 3 , where m is an index of a numerology used for a transmission, such as 0, 1, 2, 3, 4, or another number). Each slot may include a set of L symbol periods. For example, each slot may include fourteen symbol periods (e.g., as shown in  FIG. 3 ), seven symbol periods, or another number of symbol periods. In a case where the subframe includes two slots (e.g., when m=1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices of 0 through 2L−1. In some aspects, a scheduling unit for the FDD may be frame-based, subframe-based, slot-based, mini-slot based, or symbol-based. 
     As indicated above,  FIG. 3  is provided as an example. Other examples may differ from what is described with respect to  FIG. 3 . 
       FIG. 4  is a diagram illustrating an example  400  of a synchronization signal (SS) hierarchy, in accordance with the present disclosure. As shown in  FIG. 4 , the SS hierarchy may include an SS burst set  405 , which may include multiple SS bursts  410 , shown as SS burst 0 through SS burst N−1, where Nis a maximum number of repetitions of the SS burst  410  that may be transmitted by the base station. As further shown, each SS burst  410  may include one or more SS blocks (SSBs)  415 , shown as SSB 0 through SSB M−1, where M is a maximum number of SSBs  415  that can be carried by an SS burst  410 . In some aspects, different SSBs  415  may be beam-formed differently (e.g., transmitted using different beams), and may be used for cell search, cell acquisition, beam management, and/or beam selection (e.g., as part of an initial network access procedure). An SS burst set  405  may be periodically transmitted by a wireless node (e.g., base station  110 ), such as every X milliseconds, as shown in  FIG. 4 . In some aspects, an SS burst set  405  may have a fixed or dynamic length, shown as Y milliseconds in  FIG. 4 . In some cases, an SS burst set  405  or an SS burst  410  may be referred to as a discovery reference signal (DRS) transmission window or an SSB measurement time configuration (SMTC) window. 
     In some aspects, an SSB  415  may include resources that carry a primary synchronization signal (PSS)  420 , a secondary synchronization signal (SSS)  425 , and/or a physical broadcast channel (PBCH)  430 . In some aspects, multiple SSBs  415  are included in an SS burst  410  (e.g., with transmission on different beams), and the PSS  420 , the SSS  425 , and/or the PBCH  430  may be the same across each SSB  415  of the SS burst  410 . In some aspects, a single SSB  415  may be included in an SS burst  410 . In some aspects, the SSB  415  may be at least four symbols (e.g., OFDM symbols) in length, where each symbol carries one or more of the PSS  420  (e.g., occupying one symbol), the SSS  425  (e.g., occupying one symbol), and/or the PBCH  430  (e.g., occupying two symbols). In some aspects, an SSB  415  may be referred to as an SS/PBCH block. 
     In some aspects, the symbols of an SSB  415  are consecutive, as shown in  FIG. 4 . In some aspects, the symbols of an SSB  415  are non-consecutive. Similarly, in some aspects, one or more SSBs  415  of the SS burst  410  may be transmitted in consecutive radio resources (e.g., consecutive symbols) during one or more slots. Additionally, or alternatively, one or more SSBs  415  of the SS burst  410  may be transmitted in non-consecutive radio resources. 
     In some aspects, the SS bursts  410  may have a burst period, and the SSBs  415  of the SS burst  410  may be transmitted by a wireless node (e.g., base station  110 ) according to the burst period. In this case, the SSBs  415  may be repeated during each SS burst  410 . In some aspects, the SS burst set  405  may have a burst set periodicity, whereby the SS bursts  410  of the SS burst set  405  are transmitted by the wireless node according to the fixed burst set periodicity. In other words, the SS bursts  410  may be repeated during each SS burst set  405 . 
     In some aspects, an SSB  415  may include an SSB index, which may correspond to a beam used to carry the SSB  415 . A UE  120  may monitor for and/or measure SSBs  415  using different receive (Rx) beams during an initial network access procedure and/or a cell search procedure, among other examples. Based at least in part on the monitoring and/or measuring, the UE  120  may indicate one or more SSBs  415  with a best signal parameter (e.g., a reference signal received power (RSRP) parameter) to a base station  110 . The base station  110  and the UE  120  may use the one or more indicated SSBs  415  to select one or more beams to be used for communication between the base station  110  and the UE  120  (e.g., for a random access channel (RACH) procedure). Additionally, or alternatively, the UE  120  may use the SSB  415  and/or the SSB index to determine a cell timing for a cell via which the SSB  415  is received (e.g., a serving cell). 
     As indicated above,  FIG. 4  is provided as an example. Other examples may differ from what is described with regard to  FIG. 4 . 
       FIG. 5  is a diagram illustrating an example of an SSB  500 , in accordance with the present disclosure. In some examples, the SCS for the SSB may be 15 kHz or 30 kHz in FR1 and 120 kHz or 240 kHz in FR2. 
     As described above in connection with  FIG. 4 , and as shown in  FIG. 5 , the SSB  500  may span four OFDM symbols. One symbol may be used for a PSS (symbol 0, as shown), two symbols may be used for a PBCH (symbols 1 and 3, as shown), and one symbol may be used for an SSS and a PBCH that are frequency division multiplexed (symbol 2, as shown). The PSS may use a frequency domain-based M-sequence with a length of 127 (e.g., the sequence is mapped to 127 subcarriers). The PSS may be one of three possible sequences. The SSS may use a frequency domain-based Gold Code sequence (e.g., two M-sequences) with a length of 127 (e.g., the sequence is mapped to 127 subcarriers). The SSS may be one of 1008 possible sequences. The PBCH may use a quadrature phase shift keying (QPSK) modulation, and the PBCH may be coherently demodulated using an associated DMRS. 
     As indicated above,  FIG. 5  is provided as an example. Other examples may differ from what is described with regard to  FIG. 5 . 
       FIG. 6  is a diagram illustrating an example  600  of SSB locations, in accordance with the present disclosure. A time location (e.g., slots and/or OFDM symbols) of an SSB may be according to a specified (e.g., fixed) pattern. As shown in example  600 , the time locations of SSBs may be based at least in part on an SCS, which may be 15 kHz or 30 kHz in FR1, 120 kHz or 240 kHz in FR2, or the like. For example, for a 120 kHz SCS, there may be 64 SSBs in a 5 ms half frame, and  FIG. 6  shows an example pattern for four SSBs (SSBs 0-3, where 0-3 refer to SSB indices) in two slots at the 120 kHz SCS. As another example, for a 240 kHz SCS, there may be 64 SSBs in a 5 ms half frame, and  FIG. 6  shows an example pattern for eight SSBs (SSBs 0-7, where 0-7 refer to SSB indices) in four slots at the 240 kHz SCS. 
     The time locations for SSBs, according to the patterns described above, are possible locations for SSBs. Accordingly, any set of the time locations may be used for actual SSB transmissions. In this case, a UE may receive an indication of the time locations where SSBs are to be transmitted. For example, the indication may identify the SSB positions (e.g., SSB indices) where SSBs are to be transmitted, and the SSB positions may correspond to the time locations of a pattern, as described above. 
     In FR2, for example, an SSB may be multiplexed with a control resource set (CORESET) with an index 0 (CORESET 0). CORESET 0 may be used for transmitting a physical downlink control channel (PDCCH) for system information block (SIB)  1  scheduling. CORESET 0 may have a length of one, two, or three symbols, and may include 24, 48, or 96 resource blocks. A SIB 1 may include system information that is used by a UE for cell access. The SIB 1 may also include information related to the availability and scheduling of other SIBs. 
     In some examples, an SSB may be multiplexed with a CORESET 0 using one of three possible multiplexing patterns. In a first multiplexing pattern, the SSB and the CORESET 0 may be time division multiplexed. In a second multiplexing pattern, the SSB and the CORESET 0 use different SCSs and may be frequency division multiplexed and time division multiplexed. In a third multiplexing pattern, the SSB and the CORESET 0 use the same SCS and may be frequency division multiplexed. 
     A UE may receive a master information block (MIB) that may include a configuration (e.g., pdcch-ConfigSIB1) relating to CORESET 0. The configuration may indicate (e.g., in a controlResourceSetZero parameter, which may use four bits) a multiplexing pattern for an SSB and CORESET 0, as well as a frequency offset, a quantity of resource blocks, and a quantity of symbols for CORESET 0. The configuration also may indicate (e.g., in a searchSpaceZero parameter, which may use four bits) a time location for CORESET 0, which may be only one value (e.g., a 0 value) for the second and third multiplexing patterns. 
     As indicated above,  FIG. 6  is provided as an example. Other examples may differ from what is described with regard to  FIG. 6 . 
       FIG. 7  is a diagram illustrating an example  700  of time gaps for SSBs, in accordance with the present disclosure. As shown in Table 1 below, a time duration for a symbol and a cyclic prefix (CP) may decrease proportionally with an SCS increase: 
                                                 TABLE 1               μ   0   1   2   3   4   5   6                                                                SCS    15   30   60   120   240   480   960       (kHz)                                   Tcp    4687.5   2343.8   1171.9   585.9   293.0   146.5   73.2       (ns)                                   Tsymb    66666.7   33333.3   16666.7   8333.3   4166.7   2083.3   1041.7       (ns)                    
where μ represents a numerology, Tcp is the time for a CP in nanoseconds (ns), and Tsymb is the time for a symbol in ns.
 
     In some examples, a beam switching time gap may be needed between consecutive SSB beams to facilitate a beam switching delay at a base station. The beam switching delay may be about 100 ns. As shown by reference number  705 , at lower SCSs (e.g., used currently in NR), the CP length is long enough (e.g., greater than 100 ns) to include a time gap for SSB beam switching. However, at higher SCSs (e.g., greater than 480 kHz), it may not be feasible to include a time gap in a CP that is relatively shorter in duration. As shown by reference number  710 , at higher SCSs (e.g., in higher-frequency bands), a symbol-level time gap may be used to enable SSB beam switching. For example, according to a symbol-level time gap, a symbol may be skipped between consecutive SSB beams to enable SSB beam switching. 
     In addition, switching between downlink communication and uplink communication (DL/UL switching) may be affected at a higher SCS. For example, at a higher SCS, and thus a shorter symbol duration, DL/UL switching delay may have a duration of multiple symbols (e.g., the switching delay may have a duration of a slot). Accordingly, to account for uplink segments within an SSB burst, multiple symbols may be reserved for DL/UL switching delay. As shown by reference number  715 , at a higher SCS, an SSB pattern may include one or more gap slots within SSB slots of an SSB burst. The gap slot(s) may be used for uplink traffic and/or ultra-reliable low-latency communication (URLLC) traffic. 
     As indicated above,  FIG. 7  is provided as an example. Other examples may differ from what is described with regard to  FIG. 7 . 
     In some examples, NR may operate in a frequency range between 52.6 GHz and 71 GHz. In these cases, various physical layer parameters related to initial access may be used. For example, operation in this frequency range for data channels, control channels, and/or reference signals (e.g., supporting only a normal CP) may use a 480 kHz SCS and/or a 960 kHz SCS (e.g., in addition to a 120 kHz SCS), and a maximum bandwidth may be defined. Operation with a 480 kHz SCS and a 960 kHz SCS may use a common design framework (except with respect to timelines). 
     For example, licensed and unlicensed operation in this frequency range may use up to 64 SSB beams. Moreover, a 120 kHz SCS may be used for SSBs and signals and/or channels related to initial access in an initial bandwidth part. In some examples, additional SCSs, such as a 240 kHz SCS, a 480 kHz SCS, and/or a 960 kHz SCS, may be used for SSBs, and additional SCSs, such as a 480 kHz SCS and/or a 960 kHz SCS, may be used for signals and/or channels related to initial access in an initial bandwidth part. In some examples, additional SCSs, such as a 480 kHz SCS and/or a 960 kHz SCS, may be used for SSBs that are not used for initial access. 
     In some cases, a system operating between 52.6 GHz and 71 GHz (e.g., that uses an SSB SCS of 120 kHz, 240 kHz, 480 kHz, and/or 960 kHz, as described above) may be deployed with carrier aggregation. Here, a first component carrier may use a relatively low SCS (e.g., 120 kHz) and a second component carrier may use a relatively higher SCS (e.g., 480 kHz or 960 kHz). For example, a primary component carrier (or primary cell (PCell)) may use a 120 kHz SCS for better coverage, and the primary component carrier may be aggregated with a secondary component carrier (or secondary cell (SCell)) that uses a 960 kHz SCS, for example, for a higher data rate. In some examples, beam directions for SSBs on both cells may not be time aligned. Thus, there may be considerable beam direction blockage overhead in connection with separately reserving a beam direction for PCell SSBs and SCell SSBs at different times. 
     Some techniques and apparatuses described herein provide for time alignment of beam directions used for SSB transmissions and initial access transmissions (e.g., SSB transmissions, transmissions in CORESET 0, and/or SIB 1 transmissions) associated with different SCSs. For example, an SSB beam on a first component carrier, associated with a first SCS, may be time aligned with an SSB beam on a second component carrier associated with a second SCS. In some aspects, downlink initial access channels and/or signals may use a beam pattern for a relatively higher SCS. According to the beam pattern, a time location for a downlink initial access channel and/or signal, for a particular beam, is confined within (or within a threshold quantity of symbols before or after) an SSB time location, for a corresponding beam (e.g., that uses the same direction as the particular beam), according to a beam pattern for a relatively lower SCS. In some aspects, SSBs associated with the relatively higher SCS may be time division multiplexed with SSBs associated with the relatively lower SCS (e.g., in a manner that reduces beam switching). This may be useful in unlicensed band associated with a limited transmit power (e.g., a limited effective isotropic radiated power (EIRP)), because frequency division multiplexing of SSBs on different component carriers may reduce the transmit power that can be used for the SSBs. 
     It may be beneficial to align beam directions for component cells (e.g., a PCell and an SCell) that use different SCSs. For example, if the same antenna is used for both cells, a single beam forming may be used for both cells at a given time. Moreover, a UE may use the same quasi-co-location (QCL) assumptions on both cells, thereby facilitating efficient scheduling of the UE. In addition, a UE may perform SSB measurements on both cells with greater efficiency and speed. In this way, network resources, as well as computing and battery resources of the UE, may be conserved. 
       FIG. 8  is a diagram illustrating an example  800  of beam alignment for transmissions using different SCSs, in accordance with the present disclosure. As shown in  FIG. 8 , a base station  110  may communicate with one or more UEs  120  (e.g., a first UE  120  and a second UE  120 ). In some aspects, a UE  120  may be provisioned with information that identifies one or more SSB beam patterns (e.g., time locations for SSB transmissions using different beams). For example, the information may identify respective SSB beam patterns for different SCSs (e.g., a 120 kHz SCS, a 240 kHz SCS, a 480 kHz SCS, and/or a 960 kHz SCS). As an example, according to an SSB beam pattern for a 120 kHz SCS, as shown in  FIG. 8 , an SSB using a first beam may be located in symbols 4-7, an SSB using a second beam may be located in symbols 8-11, an SSB using a third beam may be located in symbols 16-19, and an SSB using a fourth beam may be located in symbols 20-23. 
     As shown by reference number  805 , the base station  110  may transmit, and a UE  120  (e.g., the first UE  120 ) may receive, one or more SSB transmissions. The SSB transmission(s) may be associated with a first SCS. For example, the base station  110  may transmit the SSB transmission(s) on a first component carrier (e.g., a first cell, such as a PCell) that uses the first SCS. The first SCS may be a relatively smaller SCS (e.g., 120 kHz). The base station  110  may transmit the SSB transmission(s) in accordance with an SSB beam pattern (e.g., associated with the first SCS). For example, an SSB transmission that uses a particular beam may be in a particular time location (e.g., according to the SSB beam pattern). “Time location” may refer to a time period (e.g., a time duration), such as one or more symbols. 
     As shown by reference number  810 , the base station  110  may transmit, and the UE  120  (e.g., the first UE  120 ) or another UE  120  (e.g., the second UE  120 ) may receive, one or more initial access transmissions. That is, the same UE  120  may receive an SSB transmission (shown by reference number  805 ) and an initial access transmission (shown by reference number  810 ), or different UEs  120  may receive an SSB transmission and an initial access transmission, respectively. 
     An initial access transmission may be associated with one or more downlink initial access channels and/or signals. An initial access transmission may include one or more of an SSB transmission, a transmission (e.g., a PDCCH transmission) in a CORESET, or a SIB transmission (e.g., a SIB physical downlink shared channel (PDSCH) transmission). In some aspects, the transmission in the CORESET may include a transmission in a CORESET 0. In some aspects, the SIB transmission may include a SIB1 transmission (e.g., a SIB1 PDSCH transmission). For example, an initial access transmission may include only an SSB transmission, may include only an SSB transmission and a CORESET 0 transmission, or may include an SSB transmission, a CORESET 0 transmission, and a SIB1 PDSCH transmission. 
     The initial access transmission(s) may be associated with a second SCS. For example, the base station  110  may transmit the initial access transmission(s) on a second component carrier (e.g., a second cell, such as a SCell) that uses the second SCS. The second SCS may be a relatively larger SCS (e.g., 480 kHz or 960 kHz). That is, the second SCS may be larger than the first SCS. The base station  110  may transmit SSB transmission(s), of the initial access transmission(s), in accordance with an SSB beam pattern (e.g., associated with the second SCS), in a similar manner as described above. 
     In some aspects, a time location of an initial access transmission, associated with the second SCS, that uses a particular beam may be based at least in part on a time location of an SSB transmission, associated with the first SCS, that uses the particular beam (e.g., the initial access transmission and the SSB transmission may use corresponding beams, such as beams that use the same direction). For example, the time location of the initial access transmission may be confined within (e.g., exactly within) the time location of the SSB transmission. Here, the base station  110  may transmit the SSB transmission and the initial access transmission simultaneously (e.g., in the same symbols). As another example, the time location of the initial access transmission may be within a threshold time (e.g., a threshold quantity of symbols, such as one symbol, two symbols, or three symbols) before or after the time location of the SSB transmission. Here, the base station  110  may transmit the initial access transmission and the SSB transmission in a time division multiplexed manner (e.g., for communication in an unlicensed band). 
     In this way, a beam pattern, associated with the second SCS, for initial access transmissions may be specified such that a time location for a beam is within a threshold distance (e.g., confined within, or within a threshold time before or after) of a time location for the same beam according to a beam pattern, associated with the first SCS, for SSB transmissions. Accordingly, an SSB, a CORESET 0, or a SIB1 PDSCH, associated with the second SCS, may have beam alignment with an SSB associated with the first SCS. In some aspects, the first UE  120 , the second UE  120 , and/or the base station  110  may perform SSB measurement, perform an initial access procedure (e.g., transmit and/or receive random access messages), and/or perform a beam management procedure (e.g., transmit and/or receive a channel station information (CSI) report), among other examples, based at least in part on the beam alignment. 
     In some aspects, the base station  110  may transmit, and a UE  120  (e.g., the first UE  120  or the second UE  120 ) may receive, the one or more initial access transmissions according to a time gap. For example, a time gap may be between consecutive initial access transmissions (e.g., initial access transmissions that use consecutive beams according to a beam pattern). In some aspects, the time gap may be a symbol-level gap (e.g., one or more symbols), as described above. Here, the time gap may accommodate beam switching delay at the base station  110 . In some aspects, the time gap may be a slot-level gap (e.g., one or more slots), as described above. Here, the time gap may accommodate UL/DL switching delays, uplink traffic, and/or URLLC traffic. 
     In some aspects, the signals and/or channels for an initial access transmission (e.g., an SSB, a CORESET 0, and/or a SIB1 PDSCH) may be multiplexed. For example, the signals and/or channels may be time division multiplexed, frequency division multiplexed, or a combination of time division multiplexed and frequency division multiplexed. As an example, two or more of an SSB, a CORESET (e.g., CORESET 0), or a SIB (e.g., SIB1) PDSCH, for an initial access transmission, may be time division multiplexed and/or frequency division multiplexed together. In one example, the CORESET and the SIB may be time division multiplexed, and the SSB may be frequency division multiplexed with the CORESET and the SIB PDSCH. In another example, the SSB and the CORESET may be time division multiplexed, and the SSB and the CORESET may be frequency division multiplexed with the SIB PDSCH. 
     In some aspects, the signals and/or channels may be contiguous in time (e.g., back-to-back, without time gaps). For example, two or more of an SSB, a CORESET (e.g., CORESET 0), or a SIB (e.g., SIB1) PDSCH, for an initial access transmission, may be contiguous in time. As an example, the SSB, the CORESET, and the SIB PDSCH all may be contiguous in time. In some aspects, the signals and/or channels may be non-contiguous in time. For example, two or more of an SSB, a CORESET (e.g., CORESET 0), or a SIB (e.g., SIB1) PDSCH, for an initial access transmission, may be non-contiguous in time (e.g., as shown for beam 3 of example  915  in  FIG. 9 ). As an example, the SSB and the CORESET may be non-contiguous in time (and the CORESET and the SIB PDSCH may be contiguous, or non-contiguous, in time). 
     In some aspects, the signals and/or channels for different initial access transmissions (e.g., that use different beams) may have different starting times relative to time locations of corresponding SSB transmissions (e.g., associated with the first SCS). For example, a starting time of a first initial access transmission (e.g., associated with the second SCS) that uses a first beam relative to a time location of a first SSB transmission (e.g., associated with the first SCS) that uses the same first beam, may be different from a starting time of a second initial access transmission (e.g., associated with the second SCS) that uses a second beam relative to a time location of a second SSB transmission (e.g., associated with the first SCS) that uses the same second beam (e.g., as shown by examples  900  and  940  of  FIG. 9 , and examples  1000 ,  1015 , and  1035  of  FIG. 10 ). In other words, relative to a time location of an SSB transmission associated with the first SCS, a corresponding (e.g., using the same beam) initial access transmission, associated with the second SCS, may start at a beginning of the time location, at a middle of the time location, or at an end of the time location. Moreover, different initial access transmissions may use different relative starting times, as described above. 
     In some aspects, a CORESET (e.g., CORESET 0) and/or a SIB (e.g., SIB1) PDSCH, for an initial access transmission (e.g., using a particular beam), may span multiple (e.g., more than one) slots (e.g., of the second SCS). That is, the CORESET may span multiple slots and/or the SIB PDSCH may span multiple slots (e.g., as shown by examples  905 ,  910 , and  925  of  FIG. 9 , and examples  1005  and  1020  of  FIG. 10 ). In some aspects, a CORESET (e.g., CORESET 0) and/or a SIB (e.g., SIB1) PDSCH, for an initial access transmission (e.g., using a particular beam), may be confined to a single slot (e.g., of the second SCS). That is, the CORESET may be confined to a single slot and/or the SIB PDSCH may be confined to a single slot (e.g., as shown by example  920  of  FIG. 9  and example  1010  of  FIG. 10 ). For example, the CORESET and the SIB PDSCH may be confined to the same single slot. 
     In some aspects, an SSB transmission, a CORESET (e.g., CORESET 0), and a SIB (e.g., SIB1) PDSCH, for an initial access transmission (e.g., using a particular beam), may be confined to a single slot (e.g., of the second SCS). For example, the SSB transmission, the CORESET, and the SIB PDSCH may be confined to the same single slot (e.g., as shown by examples  920 ,  930 , and  935  of  FIG. 9 , and examples  1015 ,  1025 , and  1030  of  FIG. 10 ). 
     As indicated above,  FIG. 8  is provided as an example. Other examples may differ from what is described with respect to  FIG. 8 . 
       FIG. 9  is a diagram illustrating examples  900 ,  905 ,  910 ,  915 ,  920 ,  925 ,  930 ,  935 , and  940  of beam alignment for transmissions using different SCSs, in accordance with the present disclosure. These examples show various time locations for initial access channels and/or signals (e.g., an SSB, a CORESET 0, and/or a SIB1 PDSCH) at the second SCS (e.g., a 480 kHz SCS). Example time locations for SSBs at the first SCS (e.g., a 120 kHz SCS) are shown in the upper symbol timeline. 
     In example  900 , a gap slot (e.g., of the second SCS) may be included between SSBs of consecutive initial access transmissions. In example  905 , an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be time domain multiplexed. In addition, a symbol-level (e.g., of the second SCS) time gap may be between consecutive initial access transmissions. In example  910 , an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be time domain multiplexed, and there may be no time gap between consecutive initial access transmissions. In example  915 , an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be time domain multiplexed. In addition, a CORESET 0 and a SIB1 PDSCH for an initial access transmission may be confined to a single slot (e.g., of the second SCS). In example  920 , an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be time domain multiplexed. In addition, an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be confined to a single slot (e.g., of the second SCS). 
     In example  925 , an SSB for an initial access transmission may be frequency domain multiplexed with a CORESET 0 and a SIB 1 PDSCH for the initial access transmission. In example  930 , an SSB for an initial access transmission may be frequency domain multiplexed with a CORESET 0 and a SIB 1 PDSCH for the initial access transmission. In addition, an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be confined to a single slot (e.g., of the second SCS). In example  935 , an SSB and a CORESET 0 for an initial access transmission may be frequency domain multiplexed with a SIB 1 PDSCH for the initial access transmission. In addition, an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be confined to a single slot (e.g., of the second SCS). 
     In examples  900 ,  905 ,  910 ,  915 ,  920 ,  925 ,  930 , and  935 , a time location for an initial access transmission (e.g., at the second SCS) using a particular beam (e.g., Beam 1) may be within a time location for an SSB transmission (e.g., at the first SCS) using the particular beam, as described above. In example  940 , multiple gap slots (e.g., of the second SCS) may be included between SSBs of consecutive initial access transmissions. In addition, a time location for an initial access transmission (e.g., at the second SCS) using a particular beam (e.g., Beam 1) may be outside of, but within a threshold time of, a time location for an SSB transmission (e.g., at the first SCS) using the particular beam, as described above. 
     As indicated above,  FIG. 9  is provided as an example. Other examples may differ from what is described with respect to  FIG. 9 . 
       FIG. 10  is a diagram illustrating examples  1000 ,  1005 ,  1010 ,  1015 ,  1020 ,  1025 ,  1030 , and  1035  of beam alignment for transmissions using different SCSs, in accordance with the present disclosure. These examples show various time locations for initial access channels and/or signals (e.g., an SSB, a CORESET 0, and/or a SIB1 PDSCH) at the second SCS (e.g., a 960 kHz SCS). Example time locations for SSBs at the first SCS (e.g., a 120 kHz SCS) are shown in the upper symbol timeline. 
     In example  1000 , multiple gap slots (e.g., of the second SCS) may be included between SSBs of consecutive initial access transmissions. In example  1005 , an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be time domain multiplexed. In example  1010 , an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be time domain multiplexed. In addition, a CORESET 0 and a SIB1 PDSCH for an initial access transmission may be confined to a single slot (e.g., of the second SCS). For example, a timing value (k0), indicating a quantity of slots between a PDCCH in the CORESET 0 and the SIB1 PDSCH, may be zero (e.g., k0=0). In example  1015 , an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be time domain multiplexed. In addition, an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be confined to a single slot (e.g., of the second SCS). 
     In example  1020 , an SSB for an initial access transmission may be frequency domain multiplexed with a CORESET 0 and a SIB 1 PDSCH for the initial access transmission. In examples  1025  and  1030 , an SSB for an initial access transmission may be frequency domain multiplexed with a CORESET 0 and a SIB 1 PDSCH for the initial access transmission. In addition, an SSB, a CORESET 0, and a SIB1 PDSCH for an initial access transmission may be confined to a single slot (e.g., of the second SCS). In example  1030 , a start time of an initial access transmission (e.g., at the second SCS) using a particular beam (e.g., Beam 1) may not be aligned with a start time for an SSB transmission (e.g., at the first SCS) using the particular beam. 
     In examples  1000 ,  1005 ,  1010 ,  1015 ,  1020 ,  1025 , and  1030 , a time location for an initial access transmission (e.g., at the second SCS) using a particular beam (e.g., Beam 1) may be within a time location for an SSB transmission (e.g., at the first SCS) using the particular beam, as described above. In example  1035 , multiple gap slots (e.g., of the second SCS) may be included between SSBs of consecutive initial access transmissions. In addition, a time location for an initial access transmission (e.g., at the second SCS) using a particular beam (e.g., Beam 1) may be outside of, but within a threshold time of, a time location for an SSB transmission (e.g., at the first SCS) using the particular beam, as described above. 
     As indicated above,  FIG. 10  is provided as an example. Other examples may differ from what is described with respect to  FIG. 10 .

For example, the UE (e.g., using reception component  1302 , depicted in  FIG. 13 ) may receive, from the network entity, one or more initial access transmissions associated with a second SCS, as described above.
