Method for controlling channel access in wireless local area network and apparatus for the same

摘要

A method for controlling channel access performed by an access point (AP) in a wireless system is provided. The method includes: receiving at least one frame from at least one station (STA), respectively, for a specific time period, each frame including information on a contention window (CW) used when the frame is transmitted; processing information one at least one CW for each STA; determining whether to control the channel access based on the processed information on the CW; selecting an abnormal STA candidate group if it is determined that the channel access control is performed; and controlling the channel access to each STA included in the abnormal candidate STA group.

1. A method performed by an access point (AP) for controlling channel access in a wireless system, the method comprising:
receiving at least one frame from at least one station (STA) for a specific time period, each received frame including information associated with a contention window (CW) used when the frame is transmitted, the information including a CW reference value that is used to determine the CW, the CW reference value being an integer n, where:
CW=2n−1; processing the information associated with the CW for each STA; determining whether to control the channel access based on the processed information associated with the CW; selecting an abnormal STA candidate group when it is determined to control the channel access; and controlling the channel access to each STA included in the abnormal candidate STA group.
