Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first capability message to a network entity indicating that the UE may be capable of using a subset of antenna ports of a set of antenna ports for uplink sounding on a wireless band. Further, one or more antenna ports of the set of antenna ports may be available for the uplink sounding and the first capability message may include an indication of the set of antenna ports. The UE may then receive control signaling from the network entity indicating the subset of antenna ports that the UE should use for the uplink sounding based on the first capability message. As such, as part of the uplink sounding on the wireless band, the UE may transmit one or more sounding reference signals (SRSs) via the subset of antenna ports indicated by the control signaling.

Abstract: Certain aspects of the present disclosure provide techniques for physical resource block allocation alignment. An example method, performed at a first network entity, includes transmitting beamforming weights (BFWs) to a second network entity, each beamforming weight to be applied to a different bundle of one or more physical resource blocks (PRBs), transmitting, to the second network entity, one or more parameters indicative of a misalignment between an allocation of PRBs and at least one logical structure, and processing signals transmitted between the first and second network entities, with beamforming applied to PRB bundles using the BFWs, in accordance with the one or more parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication identifying whether a physical resource block (PRB) allocation boundary discontinuity is present. The UE may communicate using a precoding configuration applied based at least in part on the indication identifying whether the PRB allocation boundary discontinuity is present. Numerous other aspects are described.
