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 allocating resources for communications in a mobile telecommunication system wherein the mobile telecommunication system includes a wireless interface for a base station to communicate with communications devices and wherein a communications device is operable to transmit signals to another communications device using resources of the wireless interface and in accordance with a device-to-device communication protocol. A first pool of the resources is allocated to device-to-device communications of broadcast type and a second pool of the resources is allocated to a device-to-device communications of unicast type, the second pool of resources being separate from the first pool. The method includes a first communications device transmitting broadcast messages using resources of the first resources pool and a second communications device transmitting unicast messages using resources of the second resources pool.

Abstract: A wireless telecommunication system comprises a base station arranged to communicate messages to one or more terminal devices over a radio interface. The radio interface has a radio frame structure comprising a plurality of subframes, wherein a message may be transmitted in accordance with a first transmission scheme using transmission resources in a first number of radio subframes (e.g. one subframe) or transmitted in accordance with a second transmission scheme using transmission resources in a second number of radio subframes (e.g. with repeat transmissions in a plurality of subframes). The message is transmitted in association with an identifier to indicate a terminal device to which the message is addressed. A characteristic for the identifier, for example a value or control region search space for the identifier, is dependent on whether the message is to be transmitted in accordance with the first transmission scheme or the second transmission scheme. A terminal device to which the message is addressed determines the transmission scheme from the characteristic of the identifier and receives the message accordingly.

Abstract: A wireless telecommunication system that comprises a base station and a terminal device communicating over a radio interface. The radio interface supports a downlink control channel for conveying control messages from the base station to the terminal device and a downlink data channel (e.g. a physical downlink shared channel) for conveying higher-layer messages from the base station to the terminal device. The control messages convey information on resource allocations for the higher-layer messages on the downlink data channel. The terminal device is configured to receive a control message from the base station conveying an indication of allocated transmission resources on the downlink data channel and determine a validity period for the control-plane message. During the validity period for the control message the terminal device is configured to receive a plurality of different higher-layer messages from the base station on the downlink data channel using the allocated transmission resources.
