Claim 0:
1. A method of operating an electronic device having a phased antenna array to communicate with a wireless base station, the method comprising:
with a first set of antennas in the phased antenna array, transmitting uplink signals to the wireless base station at a first output power level;
with the phased antenna array, receiving a transmit power control (TPC) command from the wireless base station; and
with a second set of antennas in the phased antenna array, transmitting the uplink signals to the wireless base station at a second output power level based on the received TPC command, wherein the second set of antennas includes a different number of antennas than the first set of antennas, wherein the second output power level is different from the first output power level, and wherein the uplink signals transmitted by the second set of antennas include an antenna scaling indication that identifies that the electronic device has changed active antennas in the phased antenna array for transmission of the uplink signals.
