US 10,098,150 B2 · Operation method and apparatus using sectorized transmission opportunity in wireless LAN system

Abstract

The present invention relates to a wireless communication system. More specifically, disclosed are an operation method and apparatus using a sectorized transmission opportunity in a wireless LAN system. The method by which a station (STA) performs a transmission opportunity-based (TXOP-based) sectorization operation in a wireless LAN system, according to one embodiment of the present invention, comprises the steps of: determining whether an ongoing frame exchange is transmitted within a basic service set (BSS) of the STA or within an overlapping BSS (OBSS); determining whether spatially orthogonal (SO) conditions are met; and resetting a virtual carrier sensing (VCS) value of the STA, if the ongoing frame exchange is transmitted within the OBSS and the SO conditions are met.

Dependent claims

A method of performing, by a station, STA, a transmission opportunity-based, TXOP-based, sectorization operation in a wireless LAN system, the method comprising:

determining whether an ongoing frame exchange is transmitted within a basic service set, BSS, of the STA or within an overlapping BSS, OBSS, based on a COLOR bits value which is included in a downlink frame within the ongoing frame exchange,
wherein the COLOR bits value is further used to distinguish a plurality of OBSS s of the wireless LAN system;
determining whether spatially orthogonal, SO, conditions are met;
and
resetting a virtual carrier sensing, VCS, value of the STA, if the ongoing frame exchange is transmitted within the OBSS and the SO conditions are met.
