APPARATUS AND METHOD FOR CONTROLLING SLEEP CYCLE SYNCHRONIZATION OF SLEEP MODE IN WIRELESS COMMUNICATION SYSTEM
摘要
An apparatus and method for controlling sleep cycle synchronization of a sleep mode in a wireless communication system are provided. A method of operating a Mobile Station (MS) in a sleep mode state includes, if a traffic indication message and unicast data are not received during a listening window, transmitting one of a request message and a header to a Base Station (BS) to request a location of a next-scheduled listening window, and if a response for the one of the request message and the header is received, performing synchronization for a next sleep cycle.
