Power control for uplink transmissions
First Claim
1. A method of wireless communication, comprising:
- determining, by a first wireless communication device, a first power control command for use by a second wireless communication device in an uplink (UL) multi-user (MU) multiple-input-multiple-output (MIMO) (UL MU-MIMO) transmission or an UL orthogonal frequency-division multiple access (UL OFDMA) transmission, the first power control command indicating a target received signal strength indicator (RSSI) for the UL-MU-MIMO or UL OFDMA transmission; and
transmitting, by the first wireless communication device, a trigger frame to the second wireless communication device that includes the first power control command and an associated identifier identifying the second wireless communication device, the trigger frame further including a transmit power level used by the first wireless communication device in transmitting the trigger frame.

Abstract
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus is configured to determine a power control command including a target receiver power level for uplink transmission. The apparatus is configured to transmit a frame to a wireless device. The frame may include information associated with the determined target receiver power level for uplink transmission from the wireless device and a transmit power level at which the frame is to be transmitted. The information may enable the wireless device to compute a transmit power for the uplink transmission. The frame may include power control commands for other wireless devices.

11. A method for wireless communication, comprising:
-
receiving, by a first wireless communication device, a trigger frame from a second wireless communication device, the trigger frame including a first power control command for use by the first wireless communication device in an uplink (UL) multi-user (MU) multiple-input-multiple-output (MIMO) (UL MU-MIMO) transmission or an UL orthogonal frequency-division multiple access (UL OFDMA) transmission, the first power control command indicating a target received signal strength indicator (RSSI) for the UL MU-MIMO or UL OFDMA transmission, the trigger frame further including an associated identifier identifying the first wireless communication device and a transmit power level used by the second wireless communication device in transmitting the trigger frame; determining a transmit power for transmitting a frame to the second wireless communication device for the UL MU-MIMO or UL OFDMA transmission, the determination of the transmit power being based on the first power control command and the transmit power level; and transmitting the frame based on the transmit power. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
