Claim 17:
18. A method, by a base station, of receiving a physical uplink shared channel (PUSCH) based on a codebook in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), capability information including UE capability related to full power transmission mode;
transmitting, to the UE, configuration information including a codebook subset and a full power transmission mode;
transmitting, to the UE, downlink control information (DCI) including information related to a precoding matrix; and
receiving, from the UE, 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.
