Title: Pdcch repetition configuration based on l1 report

Description:
TECHNICAL FIELD 
     The present disclosure relates generally to communication systems, and more particularly, to a method of wireless communication including configuration of physical downlink control channel (PDCCH) repetition based on physical layer (L1) report from a user equipment (UE). 
     Introduction 
     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. 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, and time division synchronous code division multiple access (TD-SCDMA) systems. 
     These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.

     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 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. 
     Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements”). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on a chip (SoC), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. 
     Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise a random-access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer. 
     While aspects and implementations are described in this application by illustration to some examples, those skilled in the art will understand that additional implementations and use cases may come about in many different arrangements and scenarios. Innovations described herein may be implemented across many differing platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, implementations and/or uses may come about via integrated chip implementations and other non-module-component based devices (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail/purchasing devices, medical devices, artificial intelligence (AI)-enabled devices, etc.). While some examples may or may not be specifically directed to use cases or applications, a wide assortment of applicability of described innovations may occur. Implementations may range a spectrum from chip-level or modular components to non-modular, non-chip-level implementations and further to aggregate, distributed, or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating described aspects and features may also include additional components and features for implementation and practice of claimed and described aspect. For example, transmission and reception of wireless signals necessarily includes a number of components for analog and digital purposes (e.g., hardware components including antenna, RF-chains, power amplifiers, modulators, buffer, processor(s), interleaver, adders/summers, etc.). It is intended that innovations described herein may be practiced in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or disaggregated components, end-user devices, etc. of varying sizes, shapes, and constitution. 
       FIG.  1    is a diagram illustrating an example of a wireless communications system and an access network  100 . The wireless communications system (also referred to as a wireless wide area network (WWAN)) includes base stations  102 , UEs  104 , an Evolved Packet Core (EPC)  160 , and another core network  190  (e.g., a 5G Core (5GC)). The base stations  102  may include macrocells (high power cellular base station) and/or small cells (low power cellular base station). The macrocells include base stations. The small cells include femtocells, picocells, and microcells. 
     The base stations  102  configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC  160  through first backhaul links  132  (e.g., S1 interface). The base stations  102  configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with core network  190  through second backhaul links  184 . In addition to other functions, the base stations  102  may perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment trace, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations  102  may communicate directly or indirectly (e.g., through the EPC  160  or core network  190 ) with each other over third backhaul links  134  (e.g., X2 interface). The first backhaul links  132 , the second backhaul links  184 , and the third backhaul links  134  may be wired or wireless. 
     The base stations  102  may wirelessly communicate with the UEs  104 . Each of the base stations  102  may provide communication coverage for a respective geographic coverage area  110 . There may be overlapping geographic coverage areas  110 . For example, the small cell  102 ′ may have a coverage area  110 ′ that overlaps the coverage area  110  of one or more macro base stations  102 . A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs), which may provide service to a restricted group known as a closed subscriber group (CSG). The communication links  120  between the base stations  102  and the UEs  104  may include uplink (UL) (also referred to as reverse link) transmissions from a UE  104  to a base station  102  and/or downlink (DL) (also referred to as forward link) transmissions from a base station  102  to a UE  104 . The communication links  120  may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and/or transmit diversity. The communication links may be through one or more carriers. The base stations  102 /UEs  104  may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL). The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell). 
     Certain UEs  104  may communicate with each other using device-to-device (D2D) communication link  158 . The D2D communication link  158  may use the DL/UL WWAN spectrum. The D2D communication link  158  may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). D2D communication may be through a variety of wireless D2D communications systems, such as for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR. 
     The wireless communications system may further include a Wi-Fi access point (AP)  150  in communication with Wi-Fi stations (STAs)  152  via communication links  154 , e.g., in a 5 GHz unlicensed frequency spectrum or the like. When communicating in an unlicensed frequency spectrum, the STAs  152 /AP  150  may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available. 
     The small cell  102 ′ may operate in a licensed and/or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell  102 ′ may employ NR and use the same unlicensed frequency spectrum (e.g., 5 GHz, or the like) as used by the Wi-Fi AP  150 . The small cell  102 ′, employing NR in an unlicensed frequency spectrum, may boost coverage to and/or increase capacity of the access network. 
     The electromagnetic spectrum is often subdivided, based on frequency/wavelength, into various classes, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, 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. 
     The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR2-2 (52.6 GHz-71 GHz), FR4 (71 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band. 
     With the above aspects in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like if used herein may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR2-2, and/or FR5, or may be within the EHF band. 
     A base station  102 , whether a small cell  102 ′ or a large cell (e.g., macro base station), may include and/or be referred to as an eNB, gNodeB (gNB), or another type of base station. Some base stations, such as gNB  180  may operate in a traditional sub 6 GHz spectrum, in millimeter wave frequencies, and/or near millimeter wave frequencies in communication with the UE  104 . When the gNB  180  operates in millimeter wave or near millimeter wave frequencies, the gNB  180  may be referred to as a millimeter wave base station. The millimeter wave base station  180  may utilize beamforming  182  with the UE  104  to compensate for the path loss and short range. The base station  180  and the UE  104  may each include a plurality of antennas, such as antenna elements, antenna panels, and/or antenna arrays to facilitate the beamforming. 
     The base station  180  may transmit a beamformed signal to the UE  104  in one or more transmit directions  182 ′. The UE  104  may receive the beamformed signal from the base station  180  in one or more receive directions  182 ″. The UE  104  may also transmit a beamformed signal to the base station  180  in one or more transmit directions. The base station  180  may receive the beamformed signal from the UE  104  in one or more receive directions. The base station  180 /UE  104  may perform beam training to determine the best receive and transmit directions for each of the base station  180 /UE  104 . The transmit and receive directions for the base station  180  may or may not be the same. The transmit and receive directions for the UE  104  may or may not be the same. 
     The EPC  160  may include a Mobility Management Entity (MME)  162 , other MMEs  164 , a Serving Gateway  166 , a Multimedia Broadcast Multicast Service (MBMS) Gateway  168 , a Broadcast Multicast Service Center (BM-SC)  170 , and a Packet Data Network (PDN) Gateway  172 . The MME  162  may be in communication with a Home Subscriber Server (HSS)  174 . The MME  162  is the control node that processes the signaling between the UEs  104  and the EPC  160 . Generally, the MME  162  provides bearer and connection management. All user Internet protocol (IP) packets are transferred through the Serving Gateway  166 , which itself is connected to the PDN Gateway  172 . The PDN Gateway  172  provides UE IP address allocation as well as other functions. The PDN Gateway  172  and the BM-SC  170  are connected to the IP Services  176 . The IP Services  176  may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service, and/or other IP services. The BM-SC  170  may provide functions for MBMS user service provisioning and delivery. The BM-SC  170  may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN), and may be used to schedule MBMS transmissions. The MBMS Gateway  168  may be used to distribute MBMS traffic to the base stations  102  belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and may be responsible for session management (start/stop) and for collecting eMBMS related charging information. 
     The core network  190  may include an Access and Mobility Management Function (AMF)  192 , other AMFs  193 , a Session Management Function (SMF)  194 , and a User Plane Function (UPF)  195 . The AMF  192  may be in communication with a Unified Data Management (UDM)  196 . The AMF  192  is the control node that processes the signaling between the UEs  104  and the core network  190 . Generally, the AMF  192  provides QoS flow and session management. All user Internet protocol (IP) packets are transferred through the UPF  195 . The UPF  195  provides UE IP address allocation as well as other functions. The UPF  195  is connected to the IP Services  197 . The IP Services  197  may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a Packet Switch (PS) Streaming (PSS) Service, and/or other IP services. 
     The base station may include and/or be referred to as a gNB, Node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), a transmit reception point (TRP), or some other suitable terminology. The base station  102  provides an access point to the EPC  160  or core network  190  for a UE  104 . Examples of UEs  104  include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functioning device. Some of the UEs  104  may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc.). The UE  104  may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. In some scenarios, the term UE may also apply to one or more companion devices such as in a device constellation arrangement. One or more of these devices may collectively access the network and/or individually access the network. 
     Referring again to  FIG.  1   , in certain aspects, the UE  104  may include a PDCCH repetition configuring component  198  configured to transmit at least one of an L1 report or a CSI to a base station, and receive at least one PDCCH repetition based on a first repetition option associated with the L1 report or the CSI feedback. In certain aspects, the base station  180  may include a PDCCH repetition configuring component  199  configured to receive at least one of an L1 report or CSI from a UE, and transmit at least one PDCCH repetition based on a first repetition option associated with the L1 report or the CSI feedback received from the UE. Although the following description may be focused on 5G NR, the concepts described herein may be applicable to other similar areas, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies. 
       FIG.  2 A  is a diagram  200  illustrating an example of a first subframe within a 5G NR frame structure.  FIG.  2 B  is a diagram  230  illustrating an example of DL channels within a 5G NR subframe.  FIG.  2 C  is a diagram  250  illustrating an example of a second subframe within a 5G NR frame structure.  FIG.  2 D  is a diagram  280  illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplexed (FDD) in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for either DL or UL, or may be time division duplexed (TDD) in which for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by  FIGS.  2 A,  2 C , the 5G NR frame structure is assumed to be TDD, with subframe  4  being configured with slot format  28  (with mostly DL), where D is DL, U is UL, and F is flexible for use between DL/UL, and subframe  3  being configured with slot format  1  (with all UL). While subframes  3 ,  4  are shown with slot formats  1 ,  28 , respectively, any particular subframe may be configured with any of the various available slot formats  0 - 61 . Slot formats  0 ,  1  are all DL, UL, respectively. Other slot formats  2 - 61  include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI), or semi-statically/statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI). Note that the description infra applies also to a 5G NR frame structure that is TDD. 
       FIGS.  2 A- 2 D  illustrate a frame structure, and the aspects of the present disclosure may be applicable to other wireless communication technologies, which may have a different frame structure and/or different channels. A frame (10 ms) may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 14 or 12 symbols, depending on whether the cyclic prefix (CP) is normal or extended. For normal CP, each slot may include 14 symbols, and for extended CP, each slot may include 12 symbols. The symbols on DL may be CP orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also referred to as single carrier frequency-division multiple access (SC-FDMA) symbols) (for power limited scenarios; limited to a single stream transmission). The number of slots within a subframe is based on the CP and the numerology. The numerology defines the subcarrier spacing (SCS) and, effectively, the symbol length/duration, which is equal to 1/SCS.

     For normal CP (14 symbols/slot), different numerologies μ0 to 4 allow for 1, 2, 4, 8, and 16 slots, respectively, per subframe. For extended CP, the numerology 2 allows for 4 slots per subframe. Accordingly, for normal CP and numerology μ, there are 14 symbols/slot and 2 μ  slots/subframe. The subcarrier spacing may be equal to 2 μ *15 kHz, where μ is the numerology 0 to 4. As such, the numerology μ=0 has a subcarrier spacing of 15 kHz and the numerology μ=4 has a subcarrier spacing of 240 kHz. The symbol length/duration is inversely related to the subcarrier spacing.  FIGS.  2 A- 2 D  provide an example of normal CP with 14 symbols per slot and numerology μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a set of frames, there may be one or more different bandwidth parts (BWPs) (see  FIG.  2 B ) that are frequency division multiplexed. Each BWP may have a particular numerology and CP (normal or extended). 
     A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs)) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme. 
     As illustrated in  FIG.  2 A , some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include demodulation RS (DM-RS) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS), beam refinement RS (BRRS), and phase tracking RS (PT-RS). 
       FIG.  2 B  illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol of an RB. A PDCCH within one BWP may be referred to as a control resource set (CORESET). A UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during PDCCH monitoring occasions on the CORESET, where the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWPs may be located at greater and/or lower frequencies across the channel bandwidth. A primary synchronization signal (PSS) may be within symbol  2  of particular subframes of a frame. The PSS is used by a UE  104  to determine subframe/symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol  4  of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the DM-RS. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS)/PBCH block (also referred to as SS block (SSB)). The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and paging messages. 
     As illustrated in  FIG.  2 C , some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. The UE may transmit sounding reference signals (SRS). The SRS may be transmitted in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL. 
       FIG.  2 D  illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indicator (RI), and hybrid automatic repeat request (HARQ) acknowledgment (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACK and/or negative ACK (NACK)). The PUSCH carries data, and may additionally be used to carry a buffer status report (B SR), a power headroom report (PHR), and/or UCI. 
       FIG.  3    is a block diagram of a base station  310  in communication with a UE  350  in an access network. In the DL, IP packets from the EPC  160  may be provided to a controller/processor  375 . The controller/processor  375  implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller/processor  375  provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression/decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization. 
     The transmit (TX) processor  316  and the receive (RX) processor  370  implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding/decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation/demodulation of physical channels, and MIMO antenna processing. The TX processor  316  handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator  374  may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and/or channel condition feedback transmitted by the UE  350 . Each spatial stream may then be provided to a different antenna  320  via a separate transmitter  318  TX. Each transmitter  318  TX may modulate a radio frequency (RF) carrier with a respective spatial stream for transmission. 
     At the UE  350 , each receiver  354  RX receives a signal through its respective antenna  352 . Each receiver  354  RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor  356 . The TX processor  368  and the RX processor  356  implement layer 1 functionality associated with various signal processing functions. The RX processor  356  may perform spatial processing on the information to recover any spatial streams destined for the UE  350 . If multiple spatial streams are destined for the UE  350 , they may be combined by the RX processor  356  into a single OFDM symbol stream. The RX processor  356  then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT). The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station  310 . These soft decisions may be based on channel estimates computed by the channel estimator  358 . The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station  310  on the physical channel. The data and control signals are then provided to the controller/processor  359 , which implements layer 3 and layer 2 functionality. 
     The controller/processor  359  can be associated with a memory  360  that stores program codes and data. The memory  360  may be referred to as a computer-readable medium. In the UL, the controller/processor  359  provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC  160 . The controller/processor  359  is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations. 
     Similar to the functionality described in connection with the DL transmission by the base station  310 , the controller/processor  359  provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression/decompression, and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization. 
     Channel estimates derived by a channel estimator  358  from a reference signal or feedback transmitted by the base station  310  may be used by the TX processor  368  to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor  368  may be provided to different antenna  352  via separate transmitters  354 TX. Each transmitter  354 TX may modulate an RF carrier with a respective spatial stream for transmission. 
     The UL transmission is processed at the base station  310  in a manner similar to that described in connection with the receiver function at the UE  350 . Each receiver  318 RX receives a signal through its respective antenna  320 . Each receiver  318 RX recovers information modulated onto an RF carrier and provides the information to a RX processor  370 . 
     The controller/processor  375  can be associated with a memory  376  that stores program codes and data. The memory  376  may be referred to as a computer-readable medium. In the UL, the controller/processor  375  provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the UE  350 . IP packets from the controller/processor  375  may be provided to the EPC  160 . The controller/processor  375  is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations. 
     At least one of the TX processor  368 , the RX processor  356 , and the controller/processor  359  may be configured to perform aspects in connection with  198  of  FIG.  1   . At least one of the TX processor  316 , the RX processor  370 , and the controller/processor  375  may be configured to perform aspects in connection with  199  of  FIG.  1   . 
     In some aspects, a channel condition between a base station and a UE may change. That is, the distance between the base station and the UE may change, an obstruction may be introduced between the base station and the UE to block the beam, or the UE may experience interference based on transmissions from another wireless device. Based on the change of the channel condition, the base station may change the resource allocation and modulation and coding scheme (MCS) for data transmission to be more appropriate for the current channel conditions. This process may be referred to a link adaptation, matching of the MCS and other signal and protocol parameters to the conditions on the radio link. 
     Aspects presented herein provide for a link adaptation that may be applied to physical downlink control channel (PDCCH). In some aspects, the link adaptations for the PDCCH may include PDCCH repetition to provide coverage enhancement. That is, the base station may transmit PDCCH in a search space, and the UE may search (e.g., monitor or estimate) the search space to receive the PDCCH transmitted by the base station. The base station may transmit a plurality of PDCCHs including repetitions of the PDCCH to improve the coverage. 
     The PDCCH including downlink control information (DCI) may schedule a physical downlink shared channel (PDSCH) and a physical uplink shared channel (PUSCH). To configure the resource allocation for the scheduled PDSCH and PUSCH, the DCI may include a number of parameters. The parameters may include at least one of K0, K1, or K2, where the K0 and K2 may indicate time offset (in terms of number of slots) between the scheduling PDCCH (including the DCI) and the scheduled PDSCH and PUSCH, respectively. That is, the K0 may be a first offset between the scheduling PDCCH and the scheduled PDSCH, and the K2 may be third offset between the scheduling PDCCH and the scheduled PUSCH. The K1 may refer to a second offset between the scheduled PDSCH and an ACK/NACK feedback for the scheduled PDSCH. 
     In some aspects, the base station and the UE may be configured to provide certain level of dynamic link adaptation and/or coverage enhancement for PDCCH. In one aspect, the PDCCH repetition may be linked to the one or more previous L1 reports or other CSI feedbacks. That is, the PDCCH repetition may be associated with the L1 reports or the other CSI feedbacks previously communicated between the base station and the UE, and the base station and the UE may select one PDCCH repetition configuration based on the previous L1 reports or the other CSI feedbacks. The base station may transmit the PDCCH repetition based on the PDDCH repetition configuration, and the UE may receive the PDCCH repetition in paired search spaces or multiple monitoring occasions based on the PDDCH repetition configuration. 
       FIG.  4    is a diagram illustrating an example  400  of PDCCH repetition in wireless communication. The example  400  of the PDCCH repetition may include a UE  402  and a base station  404 . The UE  402  may generate and transmit physical layer (L1) reports  410  (or other CSI feedback) for a plurality of beams received from the base station. Here, the L1 reports  410  may include at least one of channel quality indicator (CQI), an L1 reference signal received power (RSRP) (L1-RSRP), an L1 signal-to-interference-plus-noise (SINR) (L1-SINR), or the CSI feedback. For example, the base station may transmit a CSI-RS on each of multiple beams (e.g., beams  182 ′). The UE may measure the CSI-RS received on one or more beams and transmit CSI to the base station based on the measurements. 
     The base station may receive the L1 reports  410  from the UE, and determine a set of associated beams (e.g., one or more of  182 ′) for transmitting the PDCCH repetitions  430  based on the L1 reports  410  received from the UE. In one aspect, the PDCCH repetitions  430  may be transmitted over a set of paired search spaces, and the base station may determine the set of paired search spaces based on the L1 report  410  received from the UE. 
     The base station may repeat the UE-specific PDCCH transmissions, e.g., PDCCH repetitions  430 , over multiple paired search spaces or over multiple aggregated monitoring occasions, e.g., aggregated monitoring occasions of the same search space, implicitly based on the L1 reports  410 . In one aspect, the base station may configure the PDCCH repetitions  430  over the multiple paired search spaces based on the L1 reports  410 . In another aspect, the base station may configure the PDCCH repetitions  430  over the multiple aggregated monitoring occasions based on the L1 reports  410 . In another aspect, the base station may configure the PDCCH repetitions  430  over the multiple paired search spaces or the multiple aggregated monitoring occasions based on a history (or a trend) of the L1 reports  410 . 
     Different repetition option of PDCCH may be configured as part of search space configuration. That is, the base station may transmit, to the UE, the search space configuration including one or more PDCCH repetition options, and the one or more PDCCH repetition options may be associated with the L1 reports  410 . 
     In some aspect, at least one PDCCH repetition option of the configured one or more PDCCH repetition options may include PDCCH repetitions  430  over multiple beams. In one aspect, the set of paired search spaces may be based on the reported beams and the associated beam (or TCI state) for the CORESETs associated with the corresponding search spaces. For example, a first CORESET may be associated with a first beam (e.g., first TCI state) and a second CORESET may be associated with a second beam (e.g., a second TCI state). If the report indicates that beam  1  is the better beam, the UE may monitor for PDCCH in the first CORESET. If the report indicates that beam  2  is the better beam, the UE may monitor for the PDCCH in the second CORESET. 
     In some aspects, different PDCCH repetition options may be linked to different ranges of CQI, reported L1-RSRP, L1-SINR or a combination or a history of them. That is, the base station and the UE may select an PDCCH repetition option of the PDCCH repetition options based on the reported L1 reports  410 , and the base station may transmit the PDCCH repetitions  430  and the UE may receive the PDCCH repetitions  430  based on the selected PDCCH repetition option. 
     In some aspects, different PDCCH repetition options may be activated depending on thresholds on of the CQI, the reported L1-RSRP, the L1-SINR, or the combination or the history of them. That is, the base station may configure the UE with threshold values for the CQI, the L1-RSRP, or the L1-SINR of the current beam, and the UE may determine to activate one or more PDCCH repetition options based on the at least one of the CQI, the reported L1-RSRP, or the L1-SINR meeting the corresponding threshold values, particularly in semi-persistent scheduling (SPS) configurations. In a first example, the UE may monitor for PDCCH with repetitions if the CSI, L1-RSRP, or L1-SINR meets a threshold and may monitor for PDCCH without repetition if the CSI, L1-RSRP, or L1-SINR does not meet the threshold. In some aspects, there may be multiple thresholds and multiple repetition options. As an example, if the CSI, L1-RSRP, or L1-SINR does not meet a first threshold, the UE may monitor for the PDCCH without repetition. If the CSI, L1-RSRP, or L1-SINR meets a first threshold, the UE may monitor for the PDCCH based on a first number of repetitions. If the CSI, L1-RSRP, or L1-SINR meets a second threshold, the UE may monitor for the PDCCH based on a second number of repetitions. Although this example is described for two repetitions, the UE may compare the CSI, LI-RSRP, or L1-SINR to more than two thresholds, in some aspects. In some aspects, the threshold value of the L1-RSRP or the L1-SINR may be indicated as a 7-bit string. 
     In one example, the current beam may not be the best beam, and the L1 reports  410  may indicate its value as a 4-bit differential with respect to the best beam. The UE may use an equivalent 7-bit value for comparison to the threshold after converting the reported differential value to the absolute value. 
     The activation of the new PDCCH repetition options may happen considering a (configured or specified) processing time of the associated L1 reports  410 . That is, the base station and the UE may be configured or specified with a processing time of the L1 reports  410 , and apply the new PDCCH repetition options based on the associated L1 reports  410  after the processing time.  FIG.  5    illustrates an example of a time  512  at the UE between transmission of the report  510  and activation of the new PDCCH repetition options, at  520 , and a time  514  at the base station between reception of the report  510  and activation of the new PDCCH repetition options, at  530 . 
     In some aspects, the PDCCH repetitions  430  including downlink control information (DCI) may schedule a physical downlink shared channel (PDSCH)  440  and a physical uplink shared channel (PUSCH). To configure the resource allocation for the scheduled PDSCH  440  or PUSCH  450 , the DCI may include a number of parameters. The parameters may include at least one of K0, K1, or K2, where the K0 and K2 may indicate time offset (in terms of number of slots) between the scheduling PDCCH repetitions  430  (including the DCI) and the scheduled PDSCH  440  or PUSCH  450 , respectively. That is, the K0 may be a first offset between the scheduling PDCCH repetitions  430  and the scheduled PDSCH  440 , and the K2 may be third offset between the scheduling PDCCH repetitions  430  and the scheduled PUSCH. The K1 may refer to a second offset between the scheduled PDSCH  440  and an ACK/NACK  452  feedback for the scheduled PDSCH  440 . 
     In one aspect, the at least one of the K0 or the K2 (or the K1) may be interpreted with respect to the last PDCCH repetition  434  among the PDCCH repetitions  430 . That is, the base station and the UE may determine resources allocated for the scheduled PDSCH  440  or PUSCH  450  (or the Ack/Nack  452  for scheduled PDSCH  440 ) based on time offsets the K0 or the K2 (or the K1) from the last PDCCH repetition  434  among the PDCCH repetitions  430 . 
     In another aspect, the at least one of the K0 or the K2 (or the K1) may be interpreted with respect to the first PDCCH repetition  432  among the PDCCH repetitions  430 . That is, the base station and the UE may determine resources allocated for the scheduled PDSCH  440  or PUSCH  450  (or the Ack/Nack  452  for scheduled PDSCH  440 ) based on time offsets the K0 or the K2 (or the K1) from the first PDCCH repetition  432  among the PDCCH repetitions  430 . 
     In some aspects, the at least one of the K0 or the K2 (or the K1) may be interpreted depending on how the PDCCH copies are added to form the PDCCH repetitions  430 , e.g., the PDCCH copies may be added after the regular PDCCH occasion or before the regular PDCCH occasion. 
     In some aspects, the at least one of the K0 or the K2 (or the K1) may be interpreted depending on whether the PDCCH repetitions  430  are transmitted over multiple monitoring occasions of the same search space or over linked monitoring occasions of two (or multiple) search spaces. In some aspects, the at least one of the K0 and the K2 (or the K1) may depend on the presence of intra-slot repetition of the PDCCH repetitions  430 . 
       FIG.  5    is a call-flow diagram  500  of a method of wireless communication. The call-flow diagram  500  may include a UE  502  and a base station  504 . The UE  502  may transmit at least one of an L1 report or a CSI feedback of the current beam to the base station  504 . The base station  504  may receive the at least one of an L1 report or a CSI feedback of the current beam from the UE  502 , and transmit at least one PDCCH repetition based on a first repetition option associated with the L1 report or the CSI feedback received from the UE  502 . The UE  502  may receive, from the base station  504 , the PDCCH repetition based on the first repetition option associated with the L1 report or the CSI feedback received from the UE  502 . 
     At  506 , the base station  504  may transmit a configuration of the PDCCH repetition to the UE  502 . The UE  502  may receive a configuration of the PDCCH repetition from the base station  504 . Here, the configuration may be a search space configuration. In one aspect, the configuration of the PDCCH repetition may include a plurality of repetition options including the first repetition option associated with the L1 report or the CSI feedback. In another aspect, the configuration of the PDCCH repetition may be associated with a threshold value or a range of the L1 report or the CSI feedback, where the set of repetition options may be activated by the base station  504  or the UE  502  based on the at least one L1 report or the CSI feedback of the current beam being within the range or meeting the threshold value. 
     At  508 , the UE  502  may generate at least one of an L1 report or a CSI feedback of at least one of beam formed signal. Here, the L1 report may include at least one of CQI, an L1-RSRP, an L1-SINR, or a CSI feedback. At  510 , the UE  502  may transmit at least one of an L1 report or a CSI feedback to a base station  504 . The base station  504  may receive at least one of an L1 report or CSI feedback from the UE  502 . 
     At  520 , the UE  502  may activate a set of repetition options based on the at least one L1 report of a current beam, the set of repetition options including the first repetition option. In one aspect, the set of repetition options may be activated by the UE  502  based on the at least one L1 report or the CSI feedback of the current beam being within the range or meeting the threshold value received in the configuration of the PDCCH repetition received at  506 . In one aspect, the set of repetition options may be activated after a processing time  512  following transmission of the at least one L1 report. 
     At  522 , the UE  502  may interpret at least one parameter associated with the at least one PDCCH repetition, a scheduled PDSCH, or a scheduled PUSCH based on the first repetition option. Here, the at least one parameter may include at least one of a first offset between the at least one PDCCH repetition and the scheduled PDSCH (K0), a second offset between the scheduled PDSCH and an ACK/NACK feedback for the scheduled PDSCH (K1), and a third offset between the at least one PDCCH repetition and the scheduled PUSCH (K2). 
     At  530 , the base station  504  may activate a set of repetition options based on the at least one L1 report of a current beam, the set of repetition options including the first repetition option. In one aspect, the set of repetition options may be activated by the base station  504  based on the at least one L1 report or the CSI feedback of the current beam being within the range or meeting the threshold value received in the configuration of the PDCCH repetition received at  506 . In one aspect, the set of repetition options may be activated after a processing time  514  following reception of the at least one L1 report. 
     At  532 , the base station  504  may interpret at least one parameter associated with the at least one PDCCH repetition, a scheduled PDSCH, or a scheduled PUSCH based on the first repetition option. Here, the at least one parameter may include at least one of a first offset between the at least one PDCCH repetition and the scheduled PDSCH (K0), a second offset between the scheduled PDSCH and an ACK/NACK feedback for the scheduled PDSCH (K1), and a third offset between the at least one PDCCH repetition and the scheduled PUSCH (K2). 
     In one aspect, at least one of the K0, the K1, or the K2 may be interpreted based on a last PDCCH repetition of the at least one PDCCH repetition. In another aspect, the at least one of the K0, the K1, or the K2 may be interpreted based on a first PDCCH repetition of the at least one PDCCH repetition.

     The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects. Thus, the claims are not intended to be limited to the aspects shown herein, but is to be accorded the full scope consistent with the language claims, wherein reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Terms such as “if,” “when,” and “while” should be interpreted to mean “under the condition that” rather than imply an immediate temporal relationship or reaction. That is, these phrases, e.g., “when,” do not imply an immediate action in response to or during the occurrence of an action, but simply imply that if a condition is met then an action will occur, but without requiring a specific or immediate time constraint for the action to occur. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects. Unless specifically stated otherwise, the term “some” refers to one or more. Combinations such as “at least one of A, B, or C,” “one or more of A, B, or C,” “at least one of A, B, and C,” “one or more of A, B, and C,” and “A, B, C, or any combination thereof” include any combination of A, B, and/or C, and may include multiples of A, multiples of B, or multiples of C. Specifically, combinations such as “at least one of A, B, or C,” “one or more of A, B, or C,” “at least one of A, B, and C,” “one or more of A, B, and C,” and “A, B, C, or any combination thereof” may be A only, B only, C only, A and B, A and C, B and C, or A and B and C, where any such combinations may contain one or more member or members of A, B, or C. All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. The words “module,” “mechanism,” “element,” “device,” and the like may not be a substitute for the word “means.” As such, no claim element is to be construed as a means plus function unless the element is expressly recited using the phrase “means for.”
