METHOD AND APPARATUS FOR ACCESS IN WIRELESS LAN SYSTEM

摘要

An embodiment of the present invention provides a method for accessing to a medium by a station (STA) in a wireless LAN system, the method comprising the steps of: receiving a predetermined frame including a time stamp; identifying a restricted access window (RAW) assignment field included in the predetermined frame; and performing access in a slot determined on the basis of a subfield of the RAW assignment field when the STA belongs to a RAW related to the RAW allocation field, wherein whether the STA belongs to the RAW is determined by whether an association identifier (AID) of the STA is included in a AID range and the RAW assignment field includes a subfield indicating whether the AID range is determined by a TIM bitmap.

1. A method for performing access to a medium by a station, STA in a wireless communication system, the method comprising:
checking a Restricted Access Window, RAW, Assignment field contained in a RAW Parameter Set, RPS, element of a beacon frame; and performing the access in a slot determined based on a subfield of the RAW Assignment field when the STA belongs to a RAW group related to the RAW Assignment field, wherein whether or not the STA belongs to the RAW group is determined depending on whether or not an association identifier, AID, of the STA is within an AID range, wherein, when the RAW Assignment field is a first RAW Assignment field of the RPS element, the RAW Assignment field comprises a subfield indicating whether or not the AID range is determined by a traffic indication map, TIM, bitmap.
