1. A user equipment (UE), comprising:
a memory that stores at least one full power transmission mode capability of the UE;
a transceiver configured to transmit and receive information with a communications network; and
one or more processors configured to:
cause the transceiver to transmit a capabilities message to the communications network, the capabilities message indicating whether the UE supports each of four different full power transmission modes;
receive a configuration message from the communications network via the transceiver;
determine a selected full power transmission mode from the configuration message; and
configure the transceiver according to the selected full power transmission mode from among the four different full power transmission modes,
wherein the four different full power transmission modes include a mode in which power scaling is set equal to a ratio between a number of non-zero power ports of a configured transmitted precoder matrix indicator (TPMI) and a maximum number of ports of the UE.
