Abstract:
1. A method for updating channel information in a base station for a mobile station which is in an idle mode, the method comprising: transmitting an information element (IE) including a channel descriptor configuration change counter and a transmission frame field indicating a frame in which a channel descriptor is transmitted; and transmitting the channel descriptor to the mobile station in the frame indicated by the transmission frame field, wherein if the channel descriptor configuration change counter is changed with respect to a previously transmitted channel descriptor configuration change counter, the channel descriptor configuration change counter causes the mobile station to remain awake to receive the channel descriptor at the frame indicated by the transmission frame field even if the mobile station is scheduled to be in a paging unavailable interval, and wherein the paging unavailable interval is an interval during which the mobile station in the idle mode cannot communicate with the base station.
