1. A method performed by a User Equipment (UE) in a wireless communication system, the method comprising:
transmitting, to a base station, capability information,
wherein the capability information includes information for a transmit precoding matrix indicator (TPMI) group, supported by the UE, which delivers full transmission power, and
wherein, among precoding matrices for single layer transmission using 4 antenna ports based on TPMI indices 0 to 27, the TPMI group includes a precoding matrix comprising a single column containing at least one ‘0’;
receiving, from the base station, configuration information related to a Physical Uplink Shared Channel (PUSCH); and
receiving, from the base station, Downlink Control Information (DCI) for scheduling of the PUSCH,
wherein the DCI includes a field for precoding information and number of layers; and
transmitting, to the base station, the PUSCH based on a precoding matrix related to a TPMI index based on the field,
wherein, based on the precoding matrix related to the TPMI index being the precoding matrix in the TPMI group, a value for scaling a linear value of a PUSCH transmission power is equal to ‘1’, and
wherein the PUSCH transmission power is equally split across antenna ports on which the PUSCH is transmitted with non-zero power.
