A wireless communications system is described which comprises a base station, a relay device, and a terminal device. The terminal device is operable to receive from the base station an allocation of uplink resources for transmitting uplink data to the relay device, and to transmit uplink data to the relay device using the uplink resources allocated to the terminal device. The relay device is operable to receive the transmitted uplink data from the terminal device on the allocated resources, to receive an allocation of uplink resources for relaying the received uplink data to the base station, and to transmit the received uplink data to the base station using the uplink resources allocated to the relay device.

Uplink resource allocation for relay node based communication

A wireless communications system includes a base station, a relay device, and a terminal device. The terminal device can transmit one or more first type access request messages to request uplink resources from the base station, and if no response to the first type access request messages is received from the base station, can transmit a second type access request message. The base station is responsive to a first type access request message received from the terminal device to transmit an allocation of uplink resources to the terminal device. The relay device is responsive to a second type access request message received from the terminal device to transmit a relayed access request message to request the base station to allocate uplink resources to the terminal device. The base station is responsive to the relayed access request message to transmit an allocation of uplink resources to the terminal device.

Wireless communications system and method

A wireless communications system including a base station, a relay device, and a terminal device. The terminal device can transmit one or more first type access request messages to request uplink resources from the base station, and if no response to the first type access request messages is received from the base station, transmit a second type access request message. The base station is responsive to a first type access request message received from the terminal device to transmit an allocation of uplink resources to the terminal device. The relay device is responsive to a second type access request message received from the terminal device to transmit a relayed access request message to request the base station to allocate uplink resources to the terminal device. The base station is responsive to the relayed access request message to transmit an allocation of uplink resources to the terminal device.

Relay device and method

A wireless communications system is described which comprises a base station, a relay device, and a terminal device. The terminal device is operable to transmit a message to the base station via the relay device. The relay device is operable to add a relay header to the message received from the terminal device, the relay header comprising control information for controlling the transmission of subsequent messages from the terminal device to the relay device. The relay device is also operable to relay the message having the relay header added to the base station. By adding such control information to messages being relayed from the terminal device to the base station on the uplink, subsequent downlink communications from the base station to the terminal device can include the control information generated at the relay device (or transmission parameters derived from the control information).

A method supporting control channel change notification for at least one wireless communication unit capable of operating on a first serving communication cell and configured with access to at least one second serving communication cell in a wireless broadcast communication system. The method includes, at a broadcast server: supporting communication with at least one wireless communication unit via the at least one second serving communication cell; generating a message including an indication that a control channel change notification will be sent in the at least one first serving communication cell; transmitting the message to the at least one wireless communication unit operational in the at least one second serving communication cell; and transmitting the control channel change notification in the first serving communication cell.

Communication units and methods for control channel change notification in broadcast communication system supporting carrier aggregation

A method for supporting cross carrier indication of a control channel change notification for at least one wireless communication unit that is operating on a first serving communication cell and has been configured with access to at least one second serving communication cell in a wireless broadcast communication system. The method includes, at the base station: generating a message including a broadcast service identifier, wherein the broadcast service identifier identifies a control channel change of the at least one second serving cell accessible by the at least one wireless communication unit; and transmitting the message to the at least one wireless communication unit.

Communication units and methods for control change notification in broadcast communication

A method for supporting cross carrier indication of a control channel change notification in a wireless communication system that provides broadcast services on a plurality of carriers. The method includes, at a base station: receiving a first message including an indication of a control channel change requirement; mapping at least one single broadcast service to a plurality of component carriers; generating a second message including a control channel change notification for the broadcast service based on the mapping; and transmitting the second message on at least one component carrier to at least one wireless communication unit.
