Claim 0:
1. A method, by a user equipment (UE), of transmitting a physical uplink shared channel (PUSCH) based on a codebook in a wireless communication system, the method comprising:
transmitting, to a base station, capability information including UE capability related to full power transmission mode;
receiving, from the base station, configuration information including a codebook subset and a full power transmission mode;
receiving, from the base station, downlink control information (DCI) including information related to a precoding matrix; and
transmitting, to the base station, the PUSCH based on the precoding matrix determined based on the DCI,
wherein based on (i) the codebook subset being partialAndNonCoherent and (ii) the full power transmission mode being full power mode 1:
a subset of the codebook includes at least one specific precoding matrix including non-zero values for all antenna ports of the UE, and
the at least one specific precoding matrix is related to a rank 1 uplink transmission using 4 antenna ports.
