Method of updating channel information by a mobile station that is in power saving mode
First Claim
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, andwherein the paging unavailable interval is an interval during which the mobile station in the idle mode cannot communicate with the base station.

Abstract
A method of updating channel information by a mobile station (MS) that is in power saving mode is disclosed. More specifically, the method includes the MS which receives status information of a first channel descriptor and transmission frame information which includes when the first channel descriptor is to be transmitted. Furthermore, the MS compares status information of the first channel descriptor with status information of a second channel descriptor. Here, the second channel descriptor is stored in the MS. Lastly, if the compared status information are different, the MS receives the first channel descriptor according to the transmission frame information.
