Abstract
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.

15. A method for performing an association with an access point (AP) in a wireless local area network, the method comprising:
-
transmitting, by a station, an association request frame to the AP; and receiving, by the station, an association response frame in response to the association request frame from the AP, the association response frame including an association identifier (AID) information element comprising an AID field, an AID switch count field, and an AID interval field, the AID field indicating a new AID if the AP changes an AID of the station, the AID switch count field indicating a count value, in unit of a beacon interval, that the AP sets for the station to switch the new AID, the AID interval field indicating an interval, in unit of the beacon interval, during which the station wakes to receive a beacon frame from the AP. - View Dependent Claims (16, 17, 18, 19)

20. A wireless station performing an association with an access point (AP) in a wireless local area network, the wireless station comprising:
-
a transceiver configured to transmit and receive signals; and a processor coupled to the transceiver and configured to; instruct the transceiver to transmit an association request frame to the AP; and instruct the transceiver to receive an association response frame in response to the association request frame from the AP, the association response frame including an association identifier (AID) information element comprising an AID field, an AID switch count field, and an AID interval field, the AID field indicating a new AID if the AP changes an AID of the station, the AID switch count field indicating a count value, in unit of a beacon interval, that the AP sets for the station to switch the new AID, the AID interval field indicating an interval, in unit of the beacon interval, during which the station wakes to receive a beacon frame from the AP. - View Dependent Claims (21, 22, 23, 24)
