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.
Claims18
A method comprising:
- determining, by a user equipment (UE) having at least two transmit antennas, a transmit power level for the at least two transmit antennas on a per transmission layer or a per transmission codeword basis as a sum of transmit powers for the at least two transmit antennas;
- distributing, by the UE, the sum of transmit powers by dividing the sum of transmit powers across transmission layers or transmission codewords according to a single path loss of the at least two transmit antennas to obtain a corresponding per transmission layer or per transmission codeword power for each of the transmission layers or transmission codewords;
- dividing, by the UE, the corresponding per transmission layer or per transmission codeword power for each of the transmission layers or transmission codewords over the at least two transmit antennas to obtain a respective transmit power level for each of the transmission layers or transmission codewords for each of the at least two transmit antennas;
- and
- setting, by the UE, a power amplifier output level for each of the transmission layers or transmission codewords for each of the at least two transmit antennas in accordance with the respective transmit power level.
2 more elements
A user equipment (UE) comprising:
- at least two transmit antennas;
- at least one processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the at least one processor, the programming including instructions to:
- determine a transmit power level for the at least two transmit antennas on a per transmission layer or a per transmission codeword basis as a sum of transmit powers for the at least two transmit antennas;
- distribute the sum of transmit powers by dividing the sum of transmit powers across transmission layers or transmission codewords according to a single path loss of the at least two transmit antennas to obtain a corresponding per transmission layer or per transmission codeword power for each of the transmission layers or transmission codewords;
- distribute the corresponding per transmission layer or per transmission codeword power for each of the transmission layers or transmission codewords over the at least two transmit antennas to obtain a respective transmit power level for each of the transmission layers or transmission codewords for each of the at least two transmit antennas;
- and
- set a power amplifier output level for each of the transmission layers or transmission codewords for each of the at least two transmit antennas in accordance with the respective transmit power level.
6 more elements
A non-transitory computer-readable medium having instructions stored thereon that, when executed by a user equipment (UE), cause the UE to perform operations, the operations comprising:
- determining a transmit power level for at least two transmit antennas of the UE on a per transmission layer or a per transmission codeword basis as a sum of transmit powers for the at least two transmit antennas;
- distributing the sum of transmit powers by dividing the sum of transmit powers across transmission layers or transmission codewords according to a path loss of each of the at least two transmit antennas to obtain a corresponding per transmission layer or per transmission codeword power for each of the transmission layers or transmission codewords;
- dividing, by the UE, the corresponding per transmission layer or per transmission codeword power for each of the transmission layers or transmission codewords over the at least two transmit antennas to obtain a respective transmit power level for each of the transmission layers or transmission codewords for each of the at least two transmit antennas;
- and
- setting a power amplifier output level for each of the transmission layers or transmission codewords for each of the at least two transmit antennas in accordance with the respective transmit power level.
