Method and apparatus for transceiving beacon in wireless LAN system
First Claim
1. A method for receiving a beacon by a station (STA) in a wireless communication system, the method comprising:
- transmitting a first frame to an access point (AP);
receiving, from the AP, a second frame in response to transmitting the first frame;
determining a beacon reception time using a duration to a next target beacon transmission time (TBTT) included in the second frame, wherein the duration corresponds to a time duration from reception of the second frame to reception of the next target beacon and wherein the duration is configured by the AP when the first frame is received from the STA; and
receiving the beacon at the determined beacon reception time.

13. A station (STA) for receiving a beacon in a wireless communication system, comprising:
-
a transceiver; and a processor that; controls the transceiver to transmit a first frame to an access point (AP), controls the transceiver to receive, from the AP, a second frame in response to transmitting the first frame, determines a beacon reception time using a duration to a next target beacon transmission time (TBTT) included in the second frame, wherein the duration corresponds to a time duration from reception of the second frame to reception of the next target beacon and wherein the duration is configured by the AP when the first frame is received from the STA, and receives the beacon at the determined beacon reception time using the transceiver.
