Wireless communication method and wireless communication terminal for spatial reuse of overlapped basic service set
First Claim
1. A wireless communication terminal, the terminal comprising:
- a processor; and
a communication unit, wherein the processor is configured to;
receive a trigger frame indicating an uplink multi-user transmission, and transmit a trigger-based PHY protocol data unit (PPDU) in response to the received trigger frame, wherein the trigger-based PPDU comprises a spatial reuse parameter for spatial reuse operation of an overlapping basic service set (OBSS) terminal;
wherein a total bandwidth on which transmission of trigger-based PPDU(s) in response to the trigger frame is performed is indicated by a bandwidth field of a high efficiency signal field A (HE-SIG-A) of the trigger based-PPDU, and wherein when the total bandwidth consists of a first frequency band and a second frequency band which are non-contiguous with each other, a spatial reuse parameter for the first frequency band and a spatial reuse parameter for the second frequency band are set to the same value.

Abstract
The present invention relates to a wireless communication method and a wireless communication terminal for a spatial reuse operation of an overlapping basic service set, and more particularly, to a wireless communication method and a wireless communication terminal for supporting a spatial reuse operation of an overlapping basic service set to efficiently use a wireless resource. To this end, provided are a wireless communication terminal including: a processor; and a communication unit, wherein the processor receives a trigger frame indicating an uplink multi-user transmission, and transmits a trigger-based PHY protocol data unit (PPDU) in response to the received trigger frame, wherein the trigger-based PPDU comprises a spatial reuse parameter for spatial reuse operation of an overlapping basic service set (OBSS) terminal and a wireless communication method using the same.
