1. A method in a wireless Local Area Network (LAN) system, the method comprising:
receiving, by a station (STA), beacon frame information from an access point (AP), wherein the beacon frame information includes information related to a time at which a beacon frame is transmitted;
receiving, by the STA, a first beacon frame from the AP at a first Target Beacon Transmission Time (TBTT);
based on not receiving a second beacon frame from the AP at a second TBTT, transmitting, by the STA, request information to the AP after a request time interval has elapsed from the second TBTT, wherein the request information includes information requesting scheduling information for a restricted Target Wake Time (TWT) operation; and
receiving, by the STA, response information from the AP in response to the request information, wherein the response information includes the scheduling information for the restricted TWT operation.
