1. A method for operating user equipment (UE), comprising:
transmitting, to a base station (BS), a capability message for the VE, the capability message including a first indication of one or more first transmit precoding matrix indicators (TPMIs) for full power transmission using a first number of ports and a second indication of one or more second TPMIs for full power transmission using a second number of ports, wherein the second number of ports is different from the first number of ports, and wherein the capability message including the first indication and the second indication further implicitly indicates support for full power uplink transmission using fewer than the first and the second number of ports without explicit signaling of a full power uplink transmission capability for fewer than the first and the second number of ports;
receiving, from the BS, a message indicating a full power uplink transmission configuration for the UE; and
transmitting, to the BS, one or more uplink signals using at least one of the first number of ports or the second number of ports according to the full power uplink transmission configuration.
