Abstract
A method of communicating in a wireless system includes receiving resource scheduling information indicating a location of a resource for transmitting a packet, an indication of a target power level, and an indication of a first bandwidth, receiving an indication of a first transmission power level, determining a second transmission power level in accordance with the target power level, and at least one of the first bandwidth and the first transmission power level, and transmitting the packet at the location of the resource with the second transmission power level.
Claims18
A method of communicating in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 network, the method comprising:
- receiving, by a station, an 802.11 trigger frame that includes fields indicating a location of a resource unit allocated to the station for uplink transmission, a target uplink received signal power level, and a downlink transmit transmission power level;
- determining, by the station, an uplink transmit power level in accordance with the target uplink received signal power level and the downlink transmit power level indicated by the 802.11 trigger frame;
- and
- transmitting, by the station, an uplink packet over the resource unit in accordance with the uplink transmit power level.
A method of communicating in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 network, the method comprising:
- transmitting, by an access point, an 802.11 trigger frame that includes fields indicating a location of a resource unit allocated to a station for an uplink transmission, a target uplink received signal power level, and a downlink transmit power level;
- and
- receiving, by the access point, an uplink packet over the resource unit at the location indicated by the triggering frame, wherein the uplink packet transmitted using an uplink transmit power level that is based on the target uplink received signal power level and the downlink transmit power level indicated by the triggering frame.
A station adapted to perform power control in an Institute of Electrical and Electronics Engineers (IEEE) 802.11 network, the station comprising:
