Abstract
An OFDMA power control method includes: transmitting a first trigger frame to a station, wherein the first trigger frame includes a first target RSSI; receiving a first TB-PPDU from the station, wherein the first TB-PPDU is transmitted by the station using a first power according to the first target RSSI; measuring a first power of the first TB-PPDU to obtain a first measured RSSI; and generating a second the target RSSI according to the first measured RSSI.

An orthogonal frequency division multiple access (OFDMA) power control method, comprising:
- transmitting a first trigger frame to a station, wherein the first trigger frame comprises a first target received signal strength indicator (RSSI);
- receiving a first trigger-based packet protocol data unit (TB-PPDU) from the station, wherein the first TB-PPDU is transmitted by the station with a first transmission power according to the first target RSSI;
- measuring a first power of the first TB-PPDU to obtain a first measured RSSI;
- and
- generating a second target RSSI according to the first measured RSSI and the first target RSSI.
A device configured to control a transmission power of a station applying OFDMA, comprising:
- a transceiver circuit;
- and
- a processor circuit configured to:
- transmit a first trigger frame to the station using the transceiver circuit, wherein the first trigger frame comprises a first target RSSI;
- receive a first TB-PPDU from the station via the transceiver circuit, wherein the first TB-PPDU is transmitted by the station with a first transmission power according to the first target RSSI;
- measure a first power of the first TB-PPDU to obtain a first measured RSSI;
- and
- generate a second target RSSI according to the first measured RSSI and the first target RSSI.
