摘要： A method of scanning neighboring base stations for measuring channel quality in a wireless communication system includes receiving, by a mobile station from a serving base station, information associated with at least one neighboring base station; transmitting, by the mobile station to the serving base station, a scanning request message to request an allocation of a scanning interval for scanning, the scanning request message including parameters associated with a requested scan duration, a requested interleaving interval, and a requested scan iteration, wherein the requested interleaving interval is interleaved between each scan; and receiving, by the mobile station from the serving base station, a scanning response message including an allowed scan duration parameter in response to the scanning request message, wherein the allowed scan duration parameter is set to zero to indicate that the request for the allocation of the scanning interval is denied.

摘要： 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.

摘要： Handover execution and communication resumption in a wireless access system is provided. Performing a handover includes communicating with a serving base station through a first communication link and receiving from the serving base station, handover information associated with at least one candidate target base station. The method also includes transmitting handover indicator to the serving base station indicating a handover operation to a selected target base station and performing a ranging procedure with the selected target base station to establish a second communication link with the selected target base station while maintaining the first communication link with the serving base station. The method also includes being released from the serving base station in response to a handover complete status message from the selected target base station to the serving base station, or resuming normal communication with the serving base station if the handover fails with the selected target base station.
