20110059755METHOD OF PROVIDING LOCATION INFORMATION IN WIRELESS COMMUNICATION SYSTEM - A method of providing location information in a wireless communication system includes receiving a location information request message, including Location Based Service (LBS) control information, from a Base Station (BS), the LBS control information being information about a condition in which location information is reported, performing LBS measurement, and if the condition is satisfied, transmitting a location information response message, including location information collected through the LBS measurement, to the BS. In accordance with the present invention, in a wireless access system supporting LBS, LBS-related information can be reported irrespective of the state of a User Equipment (UE). In particular, in the case in which a UE is in an idle state, location information can be provided efficiently and rapidly.03-10-2011
20110059761METHOD FOR COMMUNICATION USING CARRIER SWITCHING IN MOBILE COMMUNICATION SYSTEM SUPPORTING MULTIPLE CARRIER - There is provided a method for transmitting data by a base station (BS) in a multicast broadcast service (MBS) supporting multiple carriers in a wireless communication system. The method comprises receiving a switching request message indicating an E-MBS service requested by a mobile station (MS), from the MS, transmitting a switching response message including information regarding a switching start time among a plurality of carriers set in the MS and transmitting data regarding an E-MBS service requested by the MS to the MS through a primary carrier, starting from the switching start time.03-10-2011
20110064016METHOD OF TRANSMITTING DATA OF MULTICAST BROADCAST SERVICE IN MOBILE WIRELESS CONNECTION SYSTEM - A method for receiving multicast broadcast service (MBS) data by a mobile station (MS) in a mobile wireless connection system which comprises receiving MBS-related information of at least one neighbor base station (BS) from a serving BS, performing handover from the serving BS to a target BS selected from the neighbor BSs, determining whether or not MBS-related information of the serving BS and MBS-related information of the target BS are identical, updating MBS-related information of the MS based on the determination results and receiving MBS data by using the updated MBS-related information of the MS, wherein the received MBS-related information of the neighbor BS comprises at least one of indication information indicating whether or not the MBS-related information of the neighbor BS and the MBS-related information of the serving BS are identical, information required to be updated among the MBS-related information of the serving BS, and every MBS-related information of the target BS is provided.03-17-2011
20110075600METHOD OF TRANSMITTING MULTICAST BROADCAST SERVICE - A method of a base station transmitting Multicast Broadcast Service (hereinafter referred to as MBS) includes transmitting MBS configuration information, including information about an MBS region which is a resource region to which MBS-related information is allocated and information about an MBS MAP, to a terminal and transmitting MBS data to the terminal through the MBS region. The information about the MBS region includes location information and a transmission parameter of the MBS region. The MBS MAP includes an MBS configuration information change indication which indicates whether the MBS configuration information is expected to change from first MBS configuration information to second MBS configuration information. MBS is effectively and persistently managed in a mobile wireless communication system supporting MBS.03-31-2011

20090310553MOBILE STATION, BASE STATION, AND METHOD FOR UPLINK SERVICE - The present invention relates to a mobile station, a base station, and a method for an uplink service that provides a high-speed data service between the base station and the mobile station in a wireless communication system. A method for providing an uplink service in a mobile station includes, after TCP data are received from a base station, measuring a partial round trip time which is a time until ACK which is a response to the received TCP data is inputted into an uplink transmission MAC buffer, transmitting information on the measured partial round trip time to the base station, receiving resource allocation information—unicast resource allocation information for transmitting the ACK to the base station in the mobile station—from the base station, and transmitting the ACK of the TCP data received from the base station on the basis of the resource allocation information to the base station.12-17-2009
20100111045BASE STATION AND METHOD FOR PROVIDING UPLINK SERVICE - A method for providing uplink service from a base station to a terminal includes: transmitting information on a TCP packet and a dedicated code to a terminal; receiving a code number from the terminal using the dedicated code; searching a requesting bandwidth for the code number and allocating resources to the terminal; and receiving the ACK packet for the TCP packet through the allocated resources from the terminal.05-06-2010
20100284332METHOD FOR TRANSMITTING AND RECEIVING DATA IN MULTI CARRIER WIRELESS ACCESS SYSTEM - There is provided a method in which a base station transmits downlink data in a wireless access system supporting multi-carriers. The method comprising negotiating with a terminal about a sleep mode parameter including information on a sleep window and a listening window, if the terminal is operating in a sleep mode, transmitting information on a carrier used for data transmission among the multi-carriers to the terminal through at least one of a medium access control (MAC) header, a MAC control message, and a control channel and transmitting data to the terminal based on the information during the listening window. Accordingly, waste of radio resources can be prevented by making efficient use of the multi-carriers even though the terminal is operating in the sleep mode.11-11-2010
20100285831METHOD OF PERFORMING HANDOVER IN MULTI CARRIER WIRELESS ACCESS SYSTEM - There is provided a method for handover of a terminal in a wireless access system using multi-carrier operation. The method comprises: receiving a handover command message from a serving base station; and performing network reentry to a target base station based on the handover command message, wherein the handover command message includes information required for handover to the target base station and information on whether the target base station supports handover using multi-carriers. Accordingly, it is possible to efficiently perform the handover in the wireless access system supporting the multi-carriers.11-11-2010
20100331018TERMINAL, METHOD FOR MANAGING THEREOF, BASE STATION AND METHOD FOR MANAGING THEREOF - A method for managing a terminal operated in an idle state is provided. The method includes entering a femto cell, determining whether a femto base station managing the femto cell has the same paging group as a macro base station managing a macro cell overlapping the femto cell, transmitting a first ranging code triggering a paging enable state to the femto base station if it is determined that the paging group is the same as the determination result, and receiving a paging message from the femto base station.12-30-2010
