摘要： A multicast management method of a base station is provided. The base station generates a CRC for a message including resource allocation information of a multicast group including a plurality of terminals, and masks the CRC by a CRC mask. The base station adds the masked CRC to the message, and then transmits the message to which the masked CRC is added to the multicast group.

摘要： A load-reducing memory module includes a plurality of memory components such as DRAMs. The memory components are organized into sets or ranks such that they can be accessed simultaneously for the full data bit-width of the memory module. A plurality of load reducing switching circuits is used to drive data bits from a memory controller to the plurality of memory components. The load reducing switching circuits are also used to multiplex the data lines from the memory components and drive the data bits to the memory controller.

摘要： In a method of managing a multicast service, a mobile station receives a message including multicast service flow update information from a base station that belongs to a multicast group zone including a base station set having at least one base station. The mobile station updates a parameter associated with a multicast service flow of the multicast service based on the multicast service flow update information. The multicast service flow update information includes a new multicast group zone ID, current multicast service identification information, and new multicast service identification information mapped to the current multicast service identification information.

摘要： A multicast broadcast service (MBS) receiving device establishes an MBS connection with an MBS transmitting device through a connection establishment message. When it is determined to receive MBS right after establishing the MBS connection, the MBS receiving device starts to receive the MBS right after establishing the MBS connection. When it is determined to not receive MBS right after establishing the MBS connection, the MBS receiving device transmits an MBS report message to the MBS transmitting device and then starts to receive the MBS.

摘要： An MBS transmitting apparatus allocates a plurality of time intervals of an MBS transmission carrier to an MBS region and a non-MBS region and generates region allocation information of the MBS region and the non-MBS region. The MBS transmitting apparatus allocates the time intervals, allocated to the MBS region, to one or more MBS zones and generates MBS zone allocation information of the one or more MBS zones. The MBS transmitting apparatus transmits the region allocation information and the MBS zone allocation information and transmits the MBS data through the time intervals allocated to the MBS region.
