6 Claims

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

generating capability information associated with a transmitted precoding matrix indicator (TPMI) indicating that the UE is able to support a full power uplink transmission, wherein the TPMI is any one of

when the UE includes two antenna ports and is any one of groups G0 . . . G6 when the UE includes four antenna ports; and

transmitting, to a base station (BS), the capability information,

wherein the TPMI, when the UE includes two antenna ports, corresponds to a non-coherent TPMI for single-layer transmission,

wherein the TPMI, when the UE includes 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 the TPMI, when the UE includes four antenna ports and is a non-coherent UE, is one of groups G0 . . . G3,

wherein the TPMI, when the UE includes four antenna ports and is a partial-coherent UE, is one of groups G0 . . . G6, and

wherein the groups G0 . . . G6 are given by:
