SYSTEM AND METHOD FOR CONTROLLING STATE TRANSITION IN SLEEP MODE AND AWAKE MODE IN A BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM

摘要

A broadband wireless access communication system having a sleep and an awake mode. A subscriber station controls the sleep mode upon receiving a denial response of a base station to a sleep request from the subscriber station to the base station. If the denial response from the base station is received, the subscriber station retransmits a sleep request to the base station after a lapse of waiting duration. If the denial response from the base station is received, the subscriber station holds retransmission of a sleep request to the base station until an unsolicited response to the sleep request is received from the base station.
