Abstract: 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.

Abstract: Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) node may receive, from a parent IAB node, a channel state information (CSI) report configuration for generation of a CSI report associated with monitoring, by the IAB node, at least one CSI-reference signal (CSI-RS) resource set, the configuration also indicating usage information for the at least one CSI-RS resource set. The IAB node may transmit a CSI resource configuration to a downstream node, the CSI resource configuration indicating, based at least in part on the usage information, a number of spatial layers of cross-link interference associated with the parent IAB node. The IAB node may receive, from the downstream node, the CSI report indicating CSI, the CSI associated with the cross-link interference based at least in part on the number of spatial layers.

Abstract: Certain aspects of the present disclosure provide techniques for handling collisions between PUCCH/PUSCH carrying certain reporting and sounding reference signals (SRS). The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop SRS or PUCCH/PUSCH transmissions scheduled on overlapping time resources in different component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal indicating one or more reference signal resource sets, the one or more reference signal resource sets comprising at least a first subset of reference signal resources associated with a first reference signal switching configuration and a second subset of reference signal resources associated with a second reference signal switching configuration. The UE may receive a trigger signal activating at least the first reference signal switching configuration or the second reference signal switching configuration. The UE may transmit, based at least in part on the trigger signal, reference signals according to the first subset of reference signal resources or second subset of reference signal resources.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station, downlink control information indicating at least a portion of a frequency domain basis vector being applied by the base station for frequency domain precoding of a reference signal scheduled for transmission via a set of antenna ports, receiving, from the base station, the reference signal that is frequency domain precoded in accordance with the at least portion of the frequency domain basis vector via the set of antenna ports, and transmitting, to the base station, a report indicating an antenna port subset of the set of antenna ports and a precoding coefficient for each antenna port of the antenna port subset.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message from a base station, and the configuration message may include an indication of one or more partial bands for channel state information reporting. Each partial band of the one or more partial bands may be less than a system bandwidth and include a plurality of frequency domain units associated with a precoder. The UE may select one or more antenna ports for each partial band of the one or more partial bands based on the configuration message and calculate channel state information including a linear combination of the selected one or more antenna ports for each partial band. The UE may transmit the channel state information including an indication of the selected antenna ports and linear combination coefficients for each partial band of the one or more partial bands
