Claim 0:
1. An apparatus for wireless communication, the apparatus comprising:
a transceiver;
a processor; and
a memory coupled to the processor, the processor configured to cause the apparatus to:
receive a channel state information-reference signal (CSI-RS) resource identifier (CRI) that indicates a resource configuration for CSI-RS for downlink (DL) channel measurement;
measure a layer 1 reference signal received power (L1-RSRP) on the CSI-RS;
transmit a report of the L1-RSRP measurement to a base station;
determine a precoding matrix for non-codebook (non-CB) uplink (UL) transmission based on the CRI and the L1-RSRP measurement in response to an UL frequency and a DL frequency being in a same band; and
perform a non-CB UL transmission using the precoding matrix.
