    Abstract: One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method includes determining a configuration of reference signal (RS) resources to be used by a user-equipment (UE) to perform beam measurements, transmitting, to the UE, an indication of the configuration of the RS resources, and receiving, from the UE, a report indicating a plurality of RS resource indicators based on the beam measurements, each of the RS resource indicators being associated with one of the RS resources. In some aspects, the BS selects a subset of the RS resources based on the report from the UE, transmits, to the UE, an indication to provide channel measurement information for the subset of the RS resources, and receives a report including the channel measurement information from the UE. The BS may also perform joint precoding of signals for transmission via the RS resources based on the channel measurement information.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may inform a base station of multiple transmission-antenna switching capabilities supported by the UE. The supported transmission-antenna switching capabilities may include a first transmission-antenna switching capability and a second transmission-antenna switching capability. The UE may receive a message that triggers the UE to switch from using a first configuration associated with the first transmission-antenna switching capability to using a second configuration associated with the second transmission-antenna switching capability. The UE may perform a sounding procedure using the second configuration associated with the second transmission-antenna switching capability based on receiving the message.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, a physical downlink control channel (PDCCH) that includes a grant for a communication scheduled via the PDCCH prior to a radio resource control configuration indicating a timing offset between the PDCCH and the communication scheduled via the PDCCH. The UE and/or the network node may determine a timing offset between the PDCCH and the communication scheduled via the PDCCH based at least in part on a default time domain resource assignment table for a subcarrier spacing associated with the communication. Numerous other aspects are described.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus may receive, from a base station via a DCI message, an indication of at least one K1 value corresponding to a plurality of physical downlink shared channel (PDSCH) transmissions over a plurality of PDSCH resources. The DCI message may comprise scheduling information for the plurality of PDSCH transmissions. The at least one K1 value may be associated with at least one physical uplink control channel (PUCCH) resource and indicative of a PDSCH-to-hybrid automatic repeat request (HARQ) timing. The apparatus may transmit, to the base station via the at least one PUCCH resource, at least one acknowledgment/negative-acknowledgment (ACK/NACK) indication associated with the at least one K1 value and corresponding to the plurality of PDSCH resources.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant that schedules multiple downlink communications, wherein the grant includes multiple start and length indicator values (SLIVs) that indicate respective time domain resource allocations (TDRAs) for the multiple downlink communications and a feedback timing indicator that indicates timing of uplink feedback communications for the multiple downlink communications. The UE may determine that there is a conflict between a timing of a first uplink feedback communication for a first downlink communication of the multiple downlink communications and a TDRA for a second downlink communication of the multiple downlink communications. The UE may adjust at least one of the TDRA for the second downlink communication or the timing of the first uplink feedback communication. Numerous other aspects are provided.
