Method of updating channel information by a mobile station that is in power saving mode
First Claim
1. A method for supporting channel information update of a mobile station which is in an idle mode in a base station, 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 the mobile station remains 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 when the channel descriptor configuration change counter is changed with respect to a last channel descriptor configuration change counter decoded by the mobile station, the mobile station continuing decoding all subsequent frames until the channel descriptor is successfully decoded if the mobile station fails to decode the channel descriptor.

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.
