Abstract
A method for communication performed by a station in a wireless local area network system is provided. The method includes receiving a first change sequence from an access point, transmitting a probe request frame to an access point in order to request updated system information, the probe request frame including the first change sequence, and receiving a probe response frame from the access point in response to the probe request frame. The probe response frame includes a second change sequence. The first change sequence and the second change sequence indicate a change of system information within a basic service set (BSS).

A method for communication performed by a station in a wireless local area network system, the method comprising:
- receiving, by a station, a first change sequence from an access point;
- transmitting, by the station, a probe request frame to an access point in order to request updated system information, the probe request frame including the first change sequence;
- and
- receiving, by the station, a probe response frame from the access point in response to the probe request frame,
- wherein the probe response frame includes a second change sequence,
- wherein the first change sequence and the second change sequence indicate a change of system information within a basic service set (BSS).
A wireless apparatus operating in a wireless local area network system, the wireless apparatus comprising:
- a transceiver transmitting and receiving frames;
- and
- a processor operably coupled to the transceiver and configured for:
- receiving a first change sequence from an access point,
- transmitting a probe request frame to an access point in order to request updated system information, the probe request frame including the first change sequence, and
- receiving a probe response frame from the access point in response to the probe request frame,
- wherein the probe response frame includes a second change sequence,
- wherein the first change sequence and the second change sequence indicate a change of system information within a basic service set (BSS).
