Abstract
A system and method for uplink multi-antenna power control in a communications system are provided. A method for user equipment operations includes determining a transmit power level for transmit antennas of the user equipment having at least two transmit antennas, and setting a power amplifier output level for each of the at least two transmit antennas in accordance with a respective transmit power level.
Claims16
A method comprising:
- determining, by a user equipment, a transmit power for a physical uplink shared channel (PUSCH) transmission in accordance with at least a bandwidth of a resource assignment for the PUSCH transmission and an offset for a single input, multiple output (SIMO) transmission mode for the PUSCH transmission;
- scaling, by the user equipment, the transmit power by a ratio of a number of transmit antennas transmitting a channel for which power control is being performed to a number of transmit antennas available for use in transmitting;
- and
- distributing, by the user equipment, the scaled transmit power substantially equally across at least two transmit antennas of the user equipment;
- and
- transmitting, by the user equipment via the at least two transmit antennas, the PUSCH transmission in accordance with the distributed transmit power.

A user equipment comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- determine a transmit power for a physical uplink shared channel (PUSCH) transmission in accordance with at least a bandwidth of a resource assignment for the PUSCH transmission and an offset for a single input, multiple output (SIMO) transmission mode for the PUSCH transmission;
- scale the transmit power by a ratio of a number of transmit antennas transmitting a channel for which power control is being performed to a number of transmit antennas available for use in transmitting;
- and
- distribute the scaled transmit power substantially equally across at least two transmit antennas of the user equipment;
- and
- transmit, via the at least two transmit antennas, the PUSCH transmission in accordance with the distributed transmit power.
