Abstract
A method of providing a multicast and broadcast service (MBS) in a multi-hop relay system is disclosed. The method of providing a multicast and broadcast service (MBS) in a multi-hop relay system comprises transmitting a first message including allocation information of a MBS zone; and providing the MBS from the MBS zone indicated by the allocation information. In this case, a downlink frame includes a downlink access zone, the MBS zone, and a downlink relay zone, and the MBS zone is allocated from the downlink frame used in a base station and a downlink frame used in a relay station at the same time.
Claims20
A method of providing a multicast and broadcast service (MBS) in a multi-hop relay system, the method comprising:
- transmitting a first message including allocation information of a MBS zone;
- and
- providing the MBS from the MBS zone indicated by the allocation information, wherein a downlink frame includes a downlink access zone, the MBS zone, and a downlink relay zone, and the MBS zone is allocated from the downlink frame used in a base station and a downlink frame used in a relay station at the same time.
A method of providing a multicast and broadcast service (MBS) in a relay station that supports a multi-hop relay, the method comprising:
- receiving a first message in the relay station from a base station, the first message including allocation information of a first MBS zone;
- receiving the MBS via the first MBS zone indicated by the allocation information from a base station;
- and
- relaying the MBS to the mobile station via the first MBS zone indicated by the allocation information,
- wherein a downlink frame used in the relay station includes a downlink transmit zone, the first MBS zone, a downlink receive zone, and a gap, and the first MBS zone is allocated from a downlink frame used in a base station and the downlink frame used in the relay station at the same time.
A mobile station comprising:
- a processor;
- a receive module;
- a transmit module;
- and
- an antenna transmitting a radio signal received from the outside to the receive module and transmitting a radio signal, which is transferred from the transmit module, to the outside,
- wherein the receive module performs demodulation and decoding for the radio signal transferred from the antenna,
- the transmit module performs modulation and coding for the data transferred from the processor, and
- the processor controls the receiving module to receive a first message including allocation information of the MBS zone from a base station to allow a MBS transmitting side to determine a MBS zone for transmitting MBS data, and to receive the MBS data from the MBS transmitting side through the MBS zone indicated by the received allocation information, and
- wherein the MBS transmitting side includes the base station and the relay station.
