If it is determined to update the TPC STA time resource and TPC STA's transmit power requested by the TPC configuration request frame 600, the AP may transmit to the STA the TPC configuration response frame 620 including update indication information and the TPC STA time resource and/or TPC STA's transmit power determined (updated) by the AP. In this case, the STA may operate on the basis of the TPC STA time resource and/or TPC STA's transmit power determined (updated) by the AP. When only one of the TPC STA time resource and the TPC STA's transmit power is updated, the other one may be determined as requested by the TPC configuration request frame 600.

If it is determined to reject the TPC STA time resource and TPC STA's transmit power requested by the TPC configuration request frame 600, the AP may transmit to the STA the TPC configuration response frame 620 including rejection indication information. In this case, the STA may not perform the TPC-based operation but may operate in a non-TPC based manner.

If it is determined to accept or update the TPC STA time resource and TPC STA's transmit power requested by the TPC configuration request frame 600, the AP may transmit information regarding the TPC STA time resource and the TPC STA's transmit power to the STA in the BSS in a broadcast manner. For example, a beacon frame 640 transmitted periodically by the AP for passive scanning may include information regarding the TPC STA time resource and the TPC STA's transmit power. Upon receiving the beacon frame 640, non-TPC STAs in the BSS may not perform channel access and uplink frame transmission on the TPC STA time resource.
