METHOD AND APPARATUS FOR ACCESSING CHANNEL IN WLAN SYSTEM

摘要

The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for accessing a channel in a WLAN system. The method for accessing a channel from a station (STA) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving from an access point (AP) a first frame including a traffic indication map (TIM) and a restricted access window (RAW) parameter set component; determining a RAW in which channel access of the STA is permitted, on the basis of the RAW parameter set (RPS) component; and transmitting a second frame to the AP from within the RAW that is determined, wherein the RPS component includes at least one RAW allocation field, and each of the at least one RAW allocation fields can include a RAW group field, a RAW starting point field, and a RAW duration field.

1. A method for performing channel access in at least one station (STA) of a wireless communication system, comprising:
receiving, from an access point (AP), a first frame containing a traffic indication map (TIM) element and a restricted access window (RAW) parameter set element; determining an RAW allowing channel access of the STA based on the RAW parameter set (RPS) element; and transmitting a second frame to the AP within the determined RAW, wherein the RPS element comprises at least one RAW assignment field, wherein each of the at least one RAW assignment field comprises a RAW group field, a RAW start time field, and a RAW duration field.
