Abstract
Methods, systems, and devices for wireless communications are described. A wireless communications system may support non-codebook-based precoding based on downlink channel predictions. A user equipment (UE) may receive control signaling indicating a channel state information (CSI) reference signal (CSI-RS) and a sounding reference signal (SRS) resource. The control signaling may instruct the UE to transmit an SRS via the SRS resource. The control signaling may indicate a differential value indicating a time after the SRS resource at which the UE is to predict CSI. The UE may receive, via the CSI-RS resource, a CSI-RS. The UE may transmit, via the SRS resource, the SRS that is precoded based on predicted CSI for a wireless channel resource that occurs in time after the SRS resource. The predicted CSI may be based on the CSI-RS.
