Abstract
A power saving method performed by a STA may comprise receiving, from an AP, a first beacon comprising a CCC value. The CCC value may be an integer value that represents a configuration instance of the AP. The STA may return from a power saving mode upon receiving the first beacon and receive a second beacon from the AP. The second beacon may be a primary beacon of the AP. The first beacon may comprise an SSID of the AP. The STA may perform an association procedure with the AP upon receiving the first beacon.
Claims17
A method performed by a station (STA), the method comprising:
- receiving, from an access point (AP), a first beacon comprising a configuration change count (CCC) value, wherein the CCC value represents a configuration instance of the AP and the CCC value represents a value which is incremented by one upon a configuration change of the AP and wraps around once a maximum value is reached;
- returning from a power saving mode upon receiving the first beacon;
- and
- receiving, from the AP, a second beacon, wherein the second beacon is a primary beacon of the AP.
A station (STA) comprising:
- a receiver configured to receive, from an access point (AP), a first beacon comprising a configuration change count (CCC) value, wherein the CCC value represents a configuration instance of the AP and the CCC value represents a value which is incremented by one upon a configuration change of the AP and wraps around once a maximum value is reached;
- circuitry configured to cause the STA to return from a power saving mode upon receipt of the first beacon;
- and
- circuitry configured to process a second beacon, wherein the second beacon is a primary beacon of the AP.
A method for causing a station (STA) to resume from a power saving mode, the method employed by an access point (AP), the method comprising:
- transmitting, from the AP, a first beacon comprising a configuration change count (CCC) value, wherein the CCC value is an integer value that represents a configuration instance of the AP and the CCC value represents a value which is incremented by one upon a configuration change of the AP and wraps around once a maximum value is reached;
- receiving a transmission from the STA, the transmission indicating the STA has returned from a power saving mode and is requesting resumption of a link with the AP;
- and
- transmitting, to the STA, a second beacon, wherein the second beacon is a primary beacon of the AP.
