Claim of US Patent No. 10,631,335

1. A wireless communication terminal, the terminal comprising:a processor; and
a communication unit,
wherein the processor is configured to:
receive a wireless frame through the communication unit, when the received frame is a very high throughput (VHT) PHY protocol data unit (PPDU), extract information of a partial association ID (AID) and information of a group ID from a preamble of the VHT PPDU,
when the group ID of the VHT PPDU is equal to a predetermined value, check whether at least some information of the partial AID of the VHT PPDU matches a partial basic service set (BSS) color value of a BSS color announced to the terminal, and
determine whether the received frame is an intra-BSS frame or an inter-BSS frame according to whether the at least some information of the partial AID matches the partial BSS color value of the BSS color announced to the terminal.
