    Abstract: A communications device and method of communicating using a communications device is disclosed for transmitting data to a mobile communications network or receiving data from a mobile communications network. The communications device comprises a transmitter configured to transmit signals representing data to an infrastructure equipment of a mobile communications network via a first wireless access interface, a receiver configured to receive signals from the infrastructure equipment of the mobile communications network via the first wireless access interface, and a controller. The controller controls the transmitter and the receiver to transmit data to the infrastructure equipment in accordance with a synchronous process in which a synchronized response is received from the infrastructure equipment, or to receive data from the infrastructure equipment in accordance with a synchronous process in which a synchronized response is transmitted to the infrastructure equipment. The controller is configured in combination with the transmitter and the receiver to transmit signals via a second wireless access interface to a communications apparatus operating as a relay node, the signals being for transmission to the infrastructure equipment by the communications apparatus as if the signals were transmitted by the communications device via the first wireless communications interface, to receive signals from the infrastructure via the first wireless access interface, to determine an additional delay caused by the transmission of the signals to the communications apparatus acting as the relay node via the second wireless access interface compared with a time taken which would have been taken to transmit the signals to the infrastructure equipment as if transmitted via the first wireless access interface, and to transmit to the infrastructure equipment an indication from which the infrastructure equipment can derive the determined additional delay for adjusting the transmission or reception of the synchronized response. By arranging for the communications device to determine the additional delay and to communicate the additional delay via the relay node to the infrastructure equipment, the infrastructure equipment can adjust the timing of transmitting or receiving the synchronous response to take account of the additional delay.

    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.
