OPERATION METHOD AND APPARATUS USING SECTORIZED TRANSMISSION OPPORTUNITY IN WIRELESS LAN SYSTEM

摘要

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.

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