Abstract
Disclosed are a method and an apparatus for an initial access over a wireless LAN. The method for an initial access by a station (STA) comprises: a step in which the STA receives initial access setup information from an access point (AP); and a step in which the STA determines whether to implement the initial access on the basis of the initial access setup information and the initial access decision information of the STA. Accordingly, the initial access of the STA can be distributed.
Claims4
An initial access method of a first station (STA), the method comprising:
- receiving, by the first STA, initial access setup information from an access point (AP), wherein the initial access setup information includes a bit sequence including a first bit and a second bit;
- determining, by the first STA, whether the first STA performs an initial access based on the initial access setup information and initial access determination information of the first STA, wherein the first bit of the bit sequence included in the initial access setup information corresponding to the initial access determination information of the first STA indicates that the first STA is not allowed to access the AP, wherein the second bit of the bit sequence included in the initial access setup information corresponding to initial access determination information of a second STA indicates that the second STA is allowed to access the AP;
- obtaining, by the first STA, an initial access barring period corresponding to a value of the first bit;
- and
- performing, by the first STA, the initial access within a determined period after the initial access barring period elapses, wherein the second STA performs the initial access before the determined period,
- wherein the initial access setup information is information for determining whether the first STA or the second STA perform the initial access,
- wherein the initial access setup information includes information on a user priority and an access category,
- wherein the user priority and the access category are information for indicating the type of traffic data of the first STA and the second STA, and
- wherein the initial access determination information of the first STA is information on the user priority and the access category corresponding to the first STA.

A station (STA) of a wireless local area network (LAN) system, the STA including:
- a radio frequency (RF) unit that transmits and receives a radio signal;
- and
- a processor, operatively connected with the RF unit, that:
- controls the RF unit to receive initial access setup information from an access point (AP), wherein the initial access setup information includes a bit sequence including a first bit and a second bit,
- determines whether the first STA performs initial access based on the initial access setup information and initial access determination information of the first STA, wherein the first bit of the bit sequence included in the initial access setup information corresponding to the initial access determination information of the first STA indicates that the first STA is not allowed to access the AP, wherein the second bit of the bit sequence included in the initial access setup information corresponding to initial access determination information of a second STA indicates that the second STA is allowed to access the AP,
- obtains an initial access barring period corresponding to a value of the first bit, and
- performs the initial access within a determined period after the initial access barring period elapses, wherein the second STA performs the initial access before the determined period,
- wherein the initial access setup information is information for determining whether the first STA or the second STA perform the initial access,
- wherein the initial access setup information includes user priority information and access category information,
- wherein the user priority and the access category are information for indicating the type of traffic data of the first STA and the second STA, and
- wherein the initial access determination information of the first STA is information on the user priority and the access category corresponding to the first STA.
