Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of first and second channel measurement resources (CMR) for measuring channel state information (CSI), each CMR associated with first and second transmission configuration indicator states (TCI). The UE may determine CSI for a joint transmission hypothesis which includes two rank indicators, two layer indicators, and two precoding matrix indicators, and may determine a priority for including each indicator in the CSI. In some cases, a UE may identify more than one CSI to transmit, and may determine an ordering of the one or more CSIs based on the CMR, and whether each of the one or more CSIs is associated with a single transmission hypothesis of the joint transmission hypothesis. Based on the various ordering rules of the CSI, the UE may generate and transmit CSI reporting.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that beam switching without an explicit beam indication or activation is allowed. The UE may transmit a channel state information (CSI) report identifying a selected beam. The UE may selectively switch to the selected beam in accordance with the indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes transmitting, to a base station, a capability parameter indicating one or more predictive retransmission feedback capabilities of the UE, receiving, from the base station, an activation indicator that indicates a predictive retransmission feedback procedure is enabled, receiving data from the base station, and transmitting a predictive retransmission feedback associated with the data to the base station, the predictive retransmission feedback being computed, in accordance with the activation indicator, prior to completing a decoding of the data.

Abstract: Methods, systems, and devices for wireless communications are described that support signaling of compressed gradient vectors in a machine learning system that utilizes federated learning. The compressed gradient vectors may be used to report stochastic gradients from multiple edge devices (e.g., multiple user equipment (UE) devices) that are combined into a global model at an edge server (e.g., a base station). A base station may configure a UE with one or more parameters for quantizing a local stochastic gradient, and for reporting the quantized local stochastic gradient in a set of compressed gradient vectors. Each vector of the compressed gradient vectors may be associated with a different stage of a multi-stage compression procedure for reporting the local stochastic gradient, and multiple reports from multiple UEs may be aggregated in a federated learning procedure associated with a machine learning algorithm.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a frequency domain resource allocation (FDRA) field in downlink control information for a transport block that is sized over multiple repetitions. The UE may reinterpret bits in the FDRA field, which indicate an allocated quantity of physical resource blocks (PRBs) greater than an allocation threshold, to determine that a PRB of the transport block for uplink transmission is a sub-PRB communication. The UE may transmit the sub-PRB communication based at least in part on reinterpreting the bits in the FDRA field. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.
