A wireless network includes a base station which can serve terminals directly, or via multi-hop transmission paths via relay stations. The base station transmits a downlink sub-frame which includes a first set of frame control information and a second set of frame control information. The second set of frame control information occupies a different position within the downlink sub-frame compared to the first set of frame control information. A relay station is able to transmit a downlink sub-frame to a terminal, or another relay station, while still being able to receive a set of frame control at a different time during the downlink sub-frame. The invention is especially useful in a wireless network in which the downlink transmissions of a base station and a relay station are synchronised to one another and where the downlink transmissions of a base station and relay station occupy the same, or similar, frequency bearer.
A method of transmitting within a wireless network comprising a base station, at least one terminal and at least one relay station, the method comprising transmitting a downlink sub-frame from the base station which comprises:
A method of transmitting within a wireless network comprising a base station and at least one terminal, the method comprising:
A method of operating a relay station within a wireless network, the relay station forming part of a multi-hop path between a base station and a terminal, the method comprising:
A method of operating a relay station within a wireless network comprising a base station, a plurality of relay stations and a terminal, the method comprising:
A transceiver apparatus for use in a base station of a wireless network comprising at least one terminal and at least one relay station, the transceiver comprising a transmit stage which is arranged to transmit a downlink sub-frame which comprises:
A transceiver apparatus for use in a base station of a wireless network comprising at least one terminal, the transceiver comprising a transmit stage which is arranged to:
A transceiver apparatus for a relay station of a wireless network comprising a base station, the relay station and a terminal, the transceiver comprising:
A transceiver apparatus for a relay station of a wireless network comprising a base station, a plurality of relay stations and a terminal, the transceiver comprising:
