Wireless communication method and wireless communication terminal using basic service set identification information determination of received frame
First Claim
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, anddetermine 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.

Abstract
The present invention relates to a wireless communication method and a wireless communication terminal using a determination of basic service set identification information of a received frame, and more particularly, to a wireless communication method and a wireless communication terminal for performing an operation according to a determination result whether the received frame is an intra-BSS frame or an inter-BSS frame. To this end, provided are a wireless communication terminal including a processor and a communication unit, wherein the processor receives a wireless frame through the communication unit, when the received frame is a VHT PPDU, extracts partial association ID (AID) information and group ID information from a preamble of the VHT PPDU, when the extracted group ID information is equal to a predetermined value, checks whether at least some information of the extracted partial AID matches a partial basic service set (BSS) color announced to the terminal, and determines whether the received frame is an intra-BSS frame or an inter-BSS frame according to whether at least some information of the partial AID matches the partial BSS color and a wireless communication method using the same.
