Abstract

A method for operating a user equipment (UE) is provided. The method comprises transmitting, to a base station (BS), UE capability information including a full power transmission capability of the UE, wherein the full power transmission capability of the UE includes a parameter S to indicate a group of full power transmit precoding matrix indicators (TPMIs); receiving, from the BS, configuration information for a physical uplink shared channel (PUSCH) transmission, wherein the configuration information includes a TPMI; determining the PUSCH transmission; determining a power level for the PUSCH transmission; and transmitting, to the BS, the PUSCH transmission with the determined power level, wherein the power level corresponds to full power based on the TPMI being included in the group of full power TPMIs, and wherein the TPMI indicates a precoding matrix and a number of layers for the PUSCH transmission.

Dependent claims

A method performed by a user equipment (UE), the method comprising:

generating capability information associated with a transmitted precoding matrix indicator (TPMI) that the UE is able to support a full power uplink transmission, the capability information indicating one or more TPMIs for two antenna ports or one or more TPMIs for four antenna ports;
and
transmitting, to a base station (BS), the capability information,
wherein each of the one or more TPMIs for two antenna ports corresponds to a non-coherent TPMI for single-layer transmission,
wherein each of the one or more TPMIs for four antenna ports corresponds to a non-coherent TPMI for single-layer transmission, a non-coherent TPMI for two-layer transmission, a non-coherent TPMI for three-layer transmission, or a partial-coherent TPMI for single layer transmission,
wherein each of the one or more TPMIs for two antenna ports corresponds to
