摘要:
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.

The present invention provides a method of a Base Station (BS) updating system information using a superframe structure in a wireless communication system, comprising transmitting a primary header including system scheduling information pertinent to an update of the system information and transmitting an updated secondary header. The system scheduling information comprises secondary header change state information indicating a change state of the updated secondary header, secondary header applying information indicating whether the secondary header change state information is applied to a current system, and a secondary header change indicator indicating the updated secondary header.

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.

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.

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.Alternatively, there is provided a method for receiving data by a mobile station (MS) in a multicast broadcast service (MBS) supporting multiple carriers in a wireless communication system. The method comprises transmitting a switching request message indicating an E-MBS service requested by the MS to a BS, receiving a switching response message including information regarding a switching start time among a plurality of carriers set in the MS from the BS, switching from a secondary carrier to a primary carrier at the switching start time and receiving data regarding an E-MBS service requested by the MS from the BS through the primary carrier.

A method for providing reliable wireless service in a femto system is provided. The method includes broadcasting information about out-of-service, which notifies that an air interface based on the femto BS is disabled, to user equipment (UE); and disabling the air interface. The information about the out-of-service comprising an identifier about a recommended BS that is another BS which the UE can enter.A method for receiving reliable service using user equipment (UE) in a wireless communication system is provided. The method includes receiving information about out-of-service, which notifies that service cannot be provided to the UE, from a femto base station (BS), the information about the out-of-service including an identifier about at least one recommended BS that is another BS which the UE can enter; and trying to enter one BS of the at least one recommended BS on the basis of the information about the out-of-service.
摘要:
Provided is a method for requesting neighbor base station information by user equipment in a wireless communication system. The method includes: searching neighbor base stations targeted for a handover; transmitting a list request message including preamble information about a neighbor base station searched by the user equipment among the neighbor base stations and a neighbor base station list request indicator indicating a request for information about the neighbor base station to a serving base station; and receiving a list response message including an identification information and system information of the neighbor base station from the serving base station.
摘要:
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.
摘要:
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.
