Abstract: A method of obtaining a virtual measurement result for an inactive channel in a wireless telecommunications system, the system including one or more terminals and a base station providing one or more active channels for communicating wireless signals with the one or more terminals, wherein a channel is inactive if it is not currently provided by the base station for use by the one or more terminals. The method includes: selecting an active channel of the one or more active channels; obtaining a first measurement result based on signals transmitted by the base station on the active channel: and deriving a virtual measurement result for the inactive channel from the first measurement result, thereby obtaining a virtual measurement result for the inactive channel.

Abstract: A communications device acting as a rely device is configured to transmit a buffer status report message indicating that the buffer is storing data received from the infrastructure equipment for transmission to a remote communications device, when predetermined conditions are satisfied or a trigger event occurs so that the transmission of the data to the remote communications device can make more efficient use of communications resources to transmit the data or the remote communications device receives the data when the remote communications device is in a state in which it should receive the data, for example when not in a reduced power state.

Abstract: A method of operating a terminal device and network infrastructure equipment in a wireless telecommunications system for communicating on a primary cell supporting a primary component carrier on radio resources within a first frequency band and a secondary cell supporting a secondary component carrier on radio resources within a second frequency band. The infrastructure equipment establishes a plural configuration settings for the secondary carrier based on measurements of radio usage in the second frequency band, which are conveyed to the terminal device. The terminal device makes channel quality measurements for the secondary component carrier according to the different configuration settings and reports these to the infrastructure equipment. Based on the measurements of channel quality for the different configurations, the infrastructure equipment selects one of the configuration settings, and conveys an indication of this to the terminal device in association with an allocation of transmission resources on the secondary component carrier.

Abstract: A mobile communications system, methods, and communication terminals. A first of plural communications terminals is configured to determine, based on current communications conditions, one of plural predetermined priority levels representing a relative ability of the first communications terminal to act as a relay node for a second of the plural communications terminals, and to transmit an indication of the determined priority level to the second communications terminals for one of the first or other communications terminals to be selected to act as a relay node for the second communications terminal. The second communications terminal is configured to receive from the first communications terminal the indication of the determined priority level, to receive from the other communications terminals indications of determined priority levels, to select one of the first communications terminals or one or more of the other communications terminals to act as a relay node for the second communications terminal.

Abstract: A method of operating a terminal device in a wireless telecommunications system that supports a connected mode of operation in which terminal devices receive a type user-plane data from the network infrastructure equipment using primary and/or secondary component carriers operating on different frequency bands and an idle mode of operation in which terminal devices do not receive that type of user-plane data from the network infrastructure equipment. The method includes: establishing a measurement configuration making measurements of radio channel conditions for radio resources within the second frequency band; making measurement of radio channel conditions for radio resources within the second frequency band in accordance with the measurement configuration while the terminal device is operating in the idle mode; determining if the measurement of radio channel conditions meets a trigger criterion, and if so, transmitting a measurement report to the network infrastructure equipment to indicate the trigger criterion has been met.

Abstract: A method of transmitting data from a first communications terminal to one or more second communications terminals includes receiving from an infrastructure equipment forming part of a wireless communications network an indication identifying a predetermined pattern of communications resources of a wireless access interface. The wireless access interface provides plural communications resources divided into time divided units. The method also includes transmitting the data in some or all of the predetermined pattern of communications resources to one or more of the second communications terminals in accordance with device to device communications. The predetermined pattern of communications resources is one of plural patterns of communications resources of the wireless access interface for plural of the time divided units. The plural patterns of communications resources are predetermined for a reduction in latency when transmitting the data from the first communications terminal and/or reducing in signalling overhead required to transmit the data.
