    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support beam preference feedback for data transmissions. Generally, the described techniques provide for wireless communications at a user equipment (UE), that may perform a measurement of one or more reference signals from a base station. The UE may transmit to the base station an indication of a beam preference for communicating with the base station based on the measurement of the one or more reference signals. The UE may receive, based on the indication of the beam preference, downlink control information from the base station, the downlink control information including an indication of a beam for a data transmission. The UE may perform or receive the data transmission using the indicated beam.

    Abstract: Aspects presented herein may enable a network entity to configure a group of UEs to simultaneously transmit reference signals and to simultaneously transmit gradient vectors to the network entity, such that the network entity may receive the gradient vectors from the group of UEs as an aggregated gradient vector over the air. In one aspect, a base transmits, to a group of UEs, a configuration that configures the group of UEs to simultaneously transmit one or more group-common reference signals and to simultaneously transmit one or more gradient vectors associated with a federated learning procedure. The network entity receives, from the group of UEs, the one or more group-common reference signals and the one or more gradient vectors based on the configuration via multiple channels. The network entity calculates an average gradient vector based on the one or more group-common reference signals and the one or more gradient vectors.

    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, a federated learning configuration comprising an indication of a power control loop for providing an update associated with a machine learning component, wherein the power control loop facilitates receiving the update at a received power that satisfies a received power condition associated with an over-the-air update aggregation procedure. The UE may transmit the update to the base station based at least in part on the federated learning configuration. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communication are described to support raw channel estimation. A base station may determine a transmission pattern for a set of multiple transmit beams, where each transmit beam may be associated with a respective reference signal, and may signal the transmission pattern to a user equipment (UE). The transmission pattern may indicate one or more sets of transmit beams, where each set may include two or more transmit beams used for concurrent transmission of respective reference signals. The set of multiple transmit beams may be associated with at least two synchronization signal blocks (SSBs), and the concurrently transmitted reference signals may each be associated with a respective orthogonal cover code. The UE may monitor for concurrently transmitted reference signals based on the transmission pattern, perform associated beamformed measurements, and transmit a channel state information report to the base station.
