Abstract: Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.

Abstract: Aspects of the present disclosure relate to techniques for codebook subset restriction (CSR). In some cases, a user equipment (UE) receives, from a network entity, codebook subset restriction (CSR) information. The UE determines, based on the CSR information, a restricted beam set for a plurality of antenna panels, determines precoding matrix indicator (PMI) feedback for the antenna panels subject to restricted beam set, and provides the PMI feedback to the network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), information identifying a quantity of demodulation reference signal (DMRS) sequences supported per antenna panel of the BS. The UE may transmit a DMRS communication having one or more DMRS sequences configured based at least in part on the quantity of DMRS sequences supported per antenna panel and scrambled using an extended DMRS scrambling identifier that is based at least in part on a physical random access channel preamble. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for uplink control information (UCI) transmission for overlapping physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resource assignments with repetition. A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving scheduling to transmit on the PUSCH in a first one or more slots associated with a first number of repetitions and scheduling to transmit on the PUCCH in a second one or more slots associated with a second number of repetitions. The scheduled transmissions overlap in at least one slot. The method includes determining which channel to transmit UCI on and which channel to drop for each of the first and second one or more slots. The method includes transmitting or dropping the UCI in the first and second one or more slots in accordance with the determination.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may configure a bandwidth part (BWP) switching configuration of a user equipment in connection with a dual active protocol stack (DAPS) handover based at least in part on a BWP switching rule; and perform the DAPS handover. Numerous other aspects are provided.

Abstract: Some aspects provide a method for wireless communication by a user equipment (UE). The method generally includes receiving signaling of a spatial preemption indication (PI), identifying, based on the spatial PI, at least one beam that the UE is preempted from using for at least one of transmitting or receiving at least one target signal, and refraining from using the identified beam for transmitting or receiving the target signal, for at least a time period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive an indication of whether a first physical downlink shared channel (PDSCH) communication is to be punctured in a set of resources in which a second PDSCH communication at least partially overlaps with the first PDSCH communication, or both the first PDSCH communication and the second PDSCH communication are to be transmitted in the set of resources. The mobile station may decode the first PDSCH communication based at least in part on the indication. Numerous other aspects are provided.

Abstract: Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes receiving first downlink (DL) control information (DCI) for scheduling resources in time in a system frame for transmission of one or more uplink (UL) data channels and hybrid automatic request (HARQ) signaling for acknowledging whether one or more downlink data channels have been successfully decoded, the one or more UL data channels and the HARQ signaling being configured based on a UL to DL resource ratio associated with a time-division duplex (TDD) subframe configuration. In certain aspects, the UE generates the one or more UL data channels and the HARQ signaling, and transmits the UL data channels and the HARQ signaling using the scheduled resources and in accordance with the TDD subframe configuration.
