20110013600METHOD OF TRANSMITTING DATA FOR REDUCING INTERFERENCE IN HIERARCHICAL CELL STRUCTURE - A method of transmitting data for reducing interference in a hierarchical cell structure including a macro base station (BS) providing multi carriers and a femto BS providing a single carrier includes performing a channel scan within an interfered carrier to acquire channel state information and neighbor femto BS information if interference with the femto BS occurs; transmitting a channel measurement report including the channel state information and the neighbor femto BS information to the macro BS; and transmitting data through a carrier changed by receiving carrier change information from the macro BS.01-20-2011
20110032873METHOD OF TRANSMITTING BROADCAST INFORMATION IN MULTIPLE CARRIER SYSTEM - A method of transmitting broadcast information by using multiple carriers is provided. The method includes: configuring a superframe for an operation of the multiple carriers; and transmitting the broadcast information through at least one primary carrier selected from the multiple carriers. Accordingly, the multiple carrier system can effectively manage respective carriers, and particularly can effectively use radio resources in transmission of broadcast information.02-10-2011
20110058511METHOD FOR TRANSMITTING DATA OF MULTICAST BROADCAST SERVICE USING SUPERFRAME HEADER IN MOBILE WIRELESS CONNECTION SYSTEM - There is provided a method of transmitting multicast broadcast service (MBS) data using a superframe including a plurality of subframes in a mobile wireless connection system, the method including transmitting MBS MAP indication information indicating the first at least one first resource unit of an MBS region in the beginning of an MBS scheduling interval (MSI) and MBS control information including subframe offset information; transmitting an MBS MAP through the first resource unit; and transmitting an MBS burst indicated by the MBS MAP, wherein the subframe offset information including an index of the subframe at a point where the MBS burst is ended.03-10-2011
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
20110149832METHOD FOR DATA TRANSMITTING IN MOBILE MULTICAST BROADCAST SERVICE - Disclosed is a method for transmitting multicast broadcast service (MBS) data in a wireless communication system, the method comprising: transmitting an MBS MAP, which comprises MBS AAI subframe offset and MBS resource index. MBS AAI subframe offset and MBS resource index indicate the end subframe (i.e., subframe offset) of MBS data and the number of resource units in the end subframe of the MBS data burst and resource allocation information about an MBS data burst, to a mobile station; and allocating resources as many as the number of resource units which is appointed by the MBS subframe offset and MBS resource index from transmission starting point of the MBS data burst on the basis of the resource allocation information and transmitting the MBS data burst using the allocated resources to the mobile station06-23-2011
