Abstract
A station determines the presence/absence of directional beam control in an access point, on the basis of received power measured when data transmitted from the access point are received, and the type of the received data. In accordance with the result of this determination, the station controls transmitting power to transmit data to the access point.
Claims2
A wireless communication system which exchanges data between an access point and plural stations, wherein said station comprises:
- a received power measurement unit which measures received power when data transmitted from said access point is received;
- a received data type detection unit which detects the type of the received data;
- a beam gain estimation unit which determines the presence/absence of directional beam control in said access point, on the basis of, the received power measured by said received power measurement unit, and the received data type detected by said received data type detection unit;
- and
- a transmitter power control unit which controls transmitting power for transmitting data to said access point, in accordance with the result of the determination by said beam gain estimation unit.
