Abstract
A data transmission method in a system comprising at least one or more relays includes transmitting by a mobile station a bandwidth allocation request message to a relay, receiving by the mobile station a bandwidth allocation message from the relay, the bandwidth allocation message including information for indicating an offset from a frame where the bandwidth allocation message is contained, waiting by the mobile station for an uplink frame or uplink subframe indicated by the offset from the frame where the bandwidth allocation message is contained, and transmitting data on the indicated frame or subframe.
Claims9
A data transmission method in a system comprising at least one or more relays, the method comprising:
- transmitting by a mobile station a bandwidth allocation request message to a relay;
- receiving, by the mobile station, a bandwidth allocation message from the relay, the bandwidth allocation message including information for indicating an offset from a frame where the bandwidth allocation message is contained;
- waiting by the mobile station for an uplink frame or uplink subframe indicated by the offset from the frame where the bandwidth allocation message is contained;
- and
- transmitting data on the indicated frame or subframe.
A terminal comprising:
- a transceiver configured to transmit a bandwidth allocation request message to a relay and receive a bandwidth allocation message from the relay, the bandwidth allocation message including information for indicating an offset from a frame where the bandwidth allocation message is contained;
- and
- a controller configured to wait for an uplink frame or uplink subframe indicated by the offset from the frame where the bandwidth allocation message is contained, and if reaching the indicated frame or subframe, control the transceiver to transmit data on the frame or subframe.
