Abstract: Certain aspects of the present disclosure provide techniques for communicating using power control parameters for multiple transmitter receiver point (mTRP) physical uplink shared channel (PUSCH) repetition. A method that may be performed by a user equipment (UE) includes receiving a sounding reference signal (SRS) configuration indicating at least a first SRS resource set and at least a second SRS resource set, receiving downlink control information (DCI) scheduling a first set of one or more PUSCH repetitions to a first TRP and a second set of one or more PUSCH repetitions to a second TRP, and transmitting the first and second sets of PUSCH repetitions using at least one of a first set of default power control parameters or a second set of default power control parameters.

Abstract: This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a medium access control (MAC) message indicating a switch to a multiple transmit receive point (M-TRP) transmission scheme. The UE may perform a communication using the M-TRP transmission scheme in accordance with the MAC message. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first downlink control information (DCI) repetition, for scheduling a physical downlink shared channel (PDSCH), wherein the first DCI repetition is associated with a first physical downlink control channel (PDCCH) candidate. The UE may receive a second DCI repetition associated with a second PDCCH candidate that is linked to the first PDCCH candidate for DCI repetition. The UE may transmit a feedback associated with a first symbol of a physical uplink control channel (PUCCH) based at least in part on determining a processing time and an additional processing time, wherein determining the additional processing time comprises determining the additional processing time based at least in part on a parameter associated with at least one of the first PDCCH candidate or the second PDCCH candidate. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a UE to indicate a support for a minimum time separation between monitoring occasions of two DCI in which at least one of the two DCI is received from a base station using linked PDCCH repetition. In one aspect, a UE transmits information indicating support for a minimum time separation between monitoring occasions for a pair of linked PDCCH candidates comprising one or more repetitions of a first DCI and a second DCI. The UE monitors for at least one of the first DCI or the second DCI based on the indicated minimum time separation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may detect that an antenna of a second wireless communication device is to perform a channel sensing procedure on a channel during a time occasion. The first wireless communication device may transmit, during the time occasion in one or more directions other than a direction of the antenna of the second wireless communication device, a signal that satisfies an energy detection threshold. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station on a granting group common (GC)-physical downlink control channel (PDCCH), a multimedia broadcast multicast service (MBMS) downlink grant that schedules an MBMS transmission at each UE of a group of UEs that includes the UE. The method also includes receiving, from the base station on a triggering GC-PDCCH, a message indicating respective feedback resources for each UE of the group of UEs. The method further includes receiving, from the base station, the MBMS transmission. The method still further includes transmitting, to the base station via the feedback resources, a feedback report based on receiving the MBMS transmission.
