Method for communication based on identifying information assignment and apparatus for the same

摘要

A communication method based on identifying information assignment in a wireless local area network (WLAN) system, performed by a station (STA), is provided. The method includes receiving an identifier assignment message from an access point (AP), wherein the identifier assignment message comprises identifying information for the STA, and TIM offset information for a time point at which at least one traffic indication map (TIM) element for the STA starts to be transmitted; receiving a first TIM element from the AP at a time point indicated by the TIM offset information; determining whether the first TIM element comprises the identifying information; and receiving a first data frame from the AP if the first TIM element contains the identifying information.

1. A method for performing an association with an access point in a wireless local area network, the method comprising:
transmitting, by a station, an association request frame to the access point; and receiving, by the station, an association response frame from the access point in response to the association request frame, the association response frame including association identifier (AID) assignment information including an AID field, an AID beacon offset field and an AID beacon interval field,
the AID field indicating an AID assigned to the station,the AID beacon offset field indicating when a traffic indication map (TIM) element corresponding to the assigned AID starts to be transmitted in a beacon frame, andthe AID beacon interval field indicating an interval at which the beacon frame having the TIM element corresponding to the assigned AID is transmitted.
