METHOD AND APPARATUS FOR UPDATING LISTEN INTERVAL IN WIRELESS LAN SYSTEM

摘要

Disclosed are a method and an apparatus for updating a listen interval in a wireless communication system. To this end, a method for updating a listen interval by a station (STA) of a wireless communication system may comprise, if an operation mode of the station is changed, a request frame including information indicating that the operation mode of the station is changed, to an access point (AP); and receiving a response frame in response to the request frame from the AP. If a value of a listen interval of the station is changed as the operation mode of the station is changed, the request frame further include a value of a new listen interval of the station.

1. A method for updating a listen interval in a station (STA) of a wireless communication system, the method comprising:
transmitting, by the STA, to an access point (AP) upon change of an operation mode of the STA, a request frame including information indicating change of the operation mode of the STA and a new listen interval value of the STA; and receiving from the AP, by the STA, a response frame in response to the request frame, wherein the operation mode of the STA is set to one of a traffic indication map (TIM) mode and a non-TIM mode, wherein when the operation mode of the STA changes to the TIM mode, the new listen interval value indicates an interval that the STA wakes to receive a beacon frame, and wherein when the operation mode of the STA changes to the non-TIM mode, the new listen interval value indicates an interval that the STA transmits at least one Power Save (PS)-Poll or trigger frame to the AP.
