Abstract:
1. A first radio station configured to communicate with a second radio station over a radio interface, comprising: signal processing and radio transceiving circuitry; a transmit buffer storing data packets for transmission to the second radio station and coupled to the signal processing and radio transceiving circuitry; and data processing circuitry, coupled to the transmit buffer and to the signal processing and radio transceiving circuitry, configured to adjust the transmit power at which the data packets are transmitted by the radio transceiving circuitry to the second radio station based on a transmission load over a predetermined time period, wherein the transmission load corresponds to an amount of data transmitted from or to be transmitted from the first radio station to the second radio station, and wherein the data processing circuitry is configured to perform the following tasks: detecting a first amount of packet data currently stored in the transmit buffer; comparing the first amount of packet data with a second amount of packet data previously detected in the transmit buffer; and determining an average transmission load using the first and second amounts of packet data.
