In some aspects, a sensing signal receiver may receive, from a sensing signal transmitter, sensing signals for passive object sensing in a plurality of beams; and transmit, to the sensing signal transmitter, feedback information that indicates an association of a set of beams, of the plurality of beams, for sensing signal transmission. Numerous other aspects are provided.

Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, information indicating one or more of sounding reference signal (SRS) ports selected by the network entity and associated linear combination coefficients, determine subband precoding based at least in part on the selected SRS ports and linear combination coefficient, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) scheduling an uplink multiple input multiple output (MIMO) communication. The UE may transmit, and the base station may receive, the uplink MIMO communication using a default sounding reference signal (SRS) resource configuration based at least in part on the UE receiving the DCI prior to a medium access control (MAC) control element (MAC-CE) selecting a subset of uplink transmission configuration indication (TCI) states included in an uplink TCI state pool configured for the UE. Numerous other aspects are provided.

A method performed by a user equipment (UE) generates local gradients for a federated learning task. The method calculates a gradient Sum-Power level based on the local gradients. The method receives a mapping between gradient Sum-Power levels and scaling factors for channel inversion coefficients to process a data block into an unencoded uplink signal. The method also determines a channel inversion coefficient based on a scaling factor obtained from the mapping and the calculated gradient Sum-Power level. The method applies analog modulation and the channel inversion coefficient to the data block to form the unencoded uplink signal. The method further transmits, to a network, the unencoded uplink signal on shared uplink resources for an over-the-air computation of global gradients for the federated learning task.

The UE may communicate, with the base station, a reference signal using a beam generated using a first beam weight vector from the selected set.
