Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive downlink control information scheduling, for a set of symbols of a slot, a plurality of physical downlink shared channels and associated intra-slot repetitions. The network node may communicate on the set of symbols of the slot, wherein the plurality of physical downlink shared channels and associated intra-slot repetitions do not collide with one or more semi-static uplink symbols of the set of symbols. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for signaling a new data indicator (NDI) and/or redundancy version (RV) for physical uplink/downlink shared channel (PxSCH) transmissions scheduled by a multi-PxSCH downlink control information (DCI) grant. In some cases, these techniques may be used even when a scheduled PxSCH transmission is invalid. In some cases, a number of bits in an NDI field of the DCI corresponds to a number of PxSCHs scheduled by the multi-PxSCH DCI grant. In some cases, a number of bits in an RV field of the DCI corresponds the number of PxSCHs scheduled by the multi-PxSCH DCI grant.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a physical downlink shared channel (PDSCH) transmission associated with a multi-PDSCH semi-persistent scheduling (SPS) that potentially conflicts with a second transmission in a slot. The UE may determine to keep at least one of the PDSCH transmission associated with the multi-PDSCH SPS or the second transmission in the slot based at least in part on one or more rules. The UE may perform, with a base station in the slot, at least one of the PDSCH transmission associated with the multi-PDSCH SPS or the second transmission that is kept based at least in part on the one or more rules. Numerous other aspects are described.

Abstract: A network node may configure a UE with more than one codeword transmission for each PDSCH and transmit DCI including multi-PDSCH grant scheduling multiple PDSCHs. The DCI may include an indication that a second TB is disabled for each PDSCH indicated by the multi-PDSCH grant. The UE may receive the DCI including multi-PDSCH grant scheduling multiple PDSCHs, the DCI including the indication that the second TB is disabled for each PDSCH indicated by the multi-PDSCH grant, and understand that the multiple PDSCHs scheduled by the multi-PDSCH grant. In one aspect, the indication may include a combination of the MCS and RV value of the associated multiple PDSCHs. In another aspect, the indication may include a pattern of the RV vector (or RVID) values of associated multiple PDSCHs.

Abstract: In some designs, UE receives an active BWP SCS value of an active BWP SCS that is 120 kHz or higher, and a reference SCS value of a reference SCS that is the same or lower than the active BWP SCS, and determines a number of consecutive slots in the active BWP associated with the same SFI based on the active BWP SCS value and the reference SCS value. UE and BS communicate on slot(s) of the active BWP based on the active BWP SCS value and the reference SCS value. In some designs, a multi-slot SFI configuration is defined for multiple SFIs.

Abstract: A UE receives, from a base station, a single downlink control information (DCI) indicating a multiple PDSCH grant for at least a first PDSCH in a first slot and a second PDSCH in a second slot. The UE receives the first PDSCH in a first set of symbols in the first slot and receives the second PDSCH in a second set of symbols in the second slot. A UE receives, from a base station, a single DCI indicating a multiple PUSCH grant for at least a first PUSCH in a first slot and a second PUSCH in a second slot. The UE transmits the first PUSCH in a first set of symbols in the first slot and transmits the second PUSCH in a second set of symbols in the second slot.

Abstract: Resource selection for communication of uplink control information may include determining cyclic shift ramping for resource block (RB) sets. A user equipment UE) may use one or more RB sets for transmitting uplink control information on a shared radio frequency spectrum such as an unlicensed band. In some examples, the UE may transmit uplink control information to a base station (BS) via consecutive RB sets. To this end, the BS may schedule consecutive RB sets for an uplink transmission by the wireless communication device and monitor each of these RB sets for uplink control information.

Abstract: A user equipment (UE) transmits, to a base station, an indication of a capability for physical downlink control channel (PDCCH) monitoring. The UE receives, from the base station, a configuration of a plurality of search space set groups based on the capability. The apparatus then monitors PDCCH candidates for a PDCCH from the base station based on a search space set group and the configuration. A base station receives, from a UE, an indication of a capability for PDCCH monitoring and transmits, to the UE, a configuration of a plurality of search space set groups based on the capability. The apparatus transmits a PDCCH to the UE based on the search space set group and the configuration associated with the search space set group.

Abstract: Wireless communications systems and methods related to multiplexing of synchronization blocks (SSBs), control resource sets (CORESETs), and system information blocks (SIBs) are provided. A user equipment (UE) receives, from a base station (BS), a first SSB of a first group of SSBs of an SSB burst set, wherein the first group of SSBs and a second group of SSBs of the SSB burst set are spaced apart in time by a group of CORESETs and SIBs. The group of CORESETs and SIBs comprises one CORESET and at least one SIB for each SSB of the first group of SSBs. The UE receives, in a first CORESET of the group of CORESETs and SIBs based on the first SSB, SIB scheduling information. The UE receives, based on the SIB scheduling information, a first SIB of the group of CORESETs and SIBs.

Abstract: Apparatus, methods, and computer-readable media for coexistence of multiple uplink control channel formats for wireless communication with power spectral density limitation are disclosed herein. A user equipment (UE) may communicate, with a base station (BS) over a random access channel on a first set of random access resources or a second set of random access resources, a random access request based on a comparison between an intended transmit power of the random access request and a reference transmit power threshold. The UE may communicate, on a first set of uplink resources, a control message for initial network access when the random access request is communicated on the first set of random access resources. The UE also may communicate, on a second set of uplink resources, the control message when the random access request is communicated on the second set of random access resources.
