Abstract: A communications device includes a transmitter to transmit signals representing data to an infrastructure equipment of a mobile communications network via a first wireless access interface and to transmit signals via a second wireless access interface to one or more communications apparatus which can act as relay nodes, a receiver to receive signals from the infrastructure equipment via the first wireless access interface and to receive signals via the second wireless access interface from the one or more communications apparatus which can act as relay nodes, and a controller. The controller can form a relay assist request message and with the transmitter and receiver to transmit the relay assist request message on the second wireless access interface for reception by the one or more communications apparatus which can act as relay nodes to assist in communicating signals representing data to the infrastructure equipment via the first wireless access interface.

Abstract: A method of operating a relay device to receive data from one or more terminal devices and relay the data to a base station in a wireless telecommunications system. The method includes receiving plural blocks of data from one or more terminal devices at different times. Each block of data is received in association with an indication of a time by which the block of data should be transmitted to the base station. The block of data are buffered at the relay node that determines earliest time by which one of the received blocks of data should be transmitted to the base station and transmits the plurality of blocks of data to the base station together in advance of this earliest time. The method reduces signalling overhead associated with transmissions from the relay device to the base station while helping to ensure data is not delayed at the relay node for longer than is acceptable for the data.

Abstract: A method of operating a terminal device in a wireless telecommunications system which, during a mode transition state, supports a first mode of operation in which the terminal device does not communicate with the wireless telecommunications system and a second mode of operation in which the terminal device does communicate with the wireless telecommunications system, the method including: transitioning from the first mode of operation to the second mode of operation at the expiration of a time period whereby the time period is defined by the data traffic pattern to the terminal device.
