Abstract
Disclosed are a method and an apparatus for initial access distribution over a wireless LAN. A method for an initial access by a station (STA) comprises: a step in which the STA receives a fast initial link setup (FILS) backoff parameter from an access point (AP); and a step in which the STA implements a backoff procedure by using the final FILS backoff parameter determined on the basis of the FILS backoff parameter and an access category of the data to be transmitted by the STA. Accordingly, the initial access of the STA can be distributed.
Claims8
A method for performing an initial access of a station (STA), the method comprising:
- reporting, by the STA, information for determining a Fast Initial Link Setup (FILS) backoff parameter to an access point (AP), wherein the FILS backoff parameter is determined based on the information, and wherein the information includes an access category of a traffic data, backoff retry count information, packet retransmission count information and latest backoff interval information;
- receiving, by the STA, the FILS backoff parameter from the AP, wherein the FILS backoff parameter includes a size of a Contention Window (CW) and an Arbitration Inter-Frame Space Number (AIFSN), and
- performing, by the STA, a backoff procedure based on the size of the CW and the AIFSN determined by the information.
A station (STA) of a wireless LAN system, the STA comprising:
- a radio frequency (RF) unit receiving a radio signal;
- and
- a processor operatively connected with the RF unit that:
- reports information for determining a Fast Initial Link Setup (FILS) backoff parameter to an Access Point (AP), wherein the FILS backoff parameter is determined based on the information, and wherein the information includes an access category of a traffic data, backoff retry count information, packet retransmission count information and latest backoff interval information;
- controls the RF unit to receive the FILS backoff parameter from the AP, wherein the FILS backoff parameter includes a size of a Contention Window (CW) and an Arbitration Inter-Frame Space Number (AIFSN), and
- performs a backoff procedure based on the size of the CW and the AIFSN determined by the information.
