Classification: CPC H | IPC H

Claim 11:
12. A user equipment (UE) configured to transmit a physical uplink shared channel (PUSCH) based on a codebook in a wireless communication system, the UE comprising:
a transmitter;
a receiver; and
a processor functionally connected to the transmitter and the receiver,
wherein the processor is configured to control the UE to:
receive, from a base station, downlink control information (DCI) for information related to a precoding matrix; and
transmit, to the base station, the PUSCH based on the precoding matrix determined based on the DCI,
wherein based on that a codebook subset is based on a codebook subset parameter configured to partialAndNonCoherent, the codebook subset includes at least one specific precoding matrix comprising non zero values for all antenna ports,
wherein the at least one specific precoding matrix is related to rank 1 uplink transmission using 4 antenna ports,
wherein the codebook includes a first codebook for a rank 1 using 4 antenna ports,
wherein the first codebook is based on one of the following tables,, TPMI index
W (ordered from left to right in increasing order of TPMI index)
