Abstract: A method of controlling power in a transmission system may include determining a first transmit power of a first transmit path, determining a second transmit power of a second transmit path, and controlling the first transmit path and the second transmit path based on a combination of the first transmit power and the second transmit power. The combination of the first transmit power and the second transmit power may include a sum of the first transmit power and the second transmit power. Controlling the first transmit path and the second transmit path may include determining a first effective power target for the first transmit path based on the first transmit power and the second transmit power, and determining a second effective power target for the second transmit path based on the first transmit power and the second transmit power.

Abstract: A method of gain step calibration by a user equipment (UE) includes selecting, a l th antenna path having a gain GT for a transmitter (Tx) of the UE and a corresponding m th antenna path having a gain GR for a receiver (Rx) of the UE; determining, a first loopback signal power for the l th antenna path having the gain GT for the transmitter (Tx) of the UE and the corresponding m th antenna path having the gain GR for the receiver (Rx) of the UE; determining, a second loopback signal power for the l th antenna path having a gain G′T for the transmitter (Tx) and the corresponding m th antenna path having the gain GR for the receiver (Rx); and determining, a transmitter gain step of the UE based on the first loopback signal power and the second loopback signal power.
