Abstract: Aspects relate to mechanisms for uplink precoding calibration for uplink/downlink reciprocity of non-codebook-based uplink precoding matrices based on power measurements of an uplink calibration reference signal. A UE can obtain a first uplink precoding matrix based on a downlink reference signal. The UE can then transmit an uplink calibration reference signal to a network entity. The uplink calibration reference signal includes a plurality of resources in which each resource is precoded with a respective second uplink precoding matrix having a respective phase shift from the first uplink precoding matrix. The UE can then receive a report from the network entity including one or more resource indexes identifying one or more resources of the plurality of resources having the highest received power(s) among the plurality of resources. Based on the report, the UE can calibrate the first uplink precoding matrix to produce a calibrated uplink precoding matrix.
