Abstract: A method of controlling communications within a wireless communications network is provided. The method comprises receiving, at a first of the infrastructure equipment acting as a donor node connected to a core network part of a wireless communications network, signals representing data from a second of the infrastructure equipment over a first communications path via one or more other infrastructure equipment acting as relay nodes, receiving, at the first infrastructure equipment, assistance information from at least one of the second infrastructure equipment and the one or more other infrastructure equipment acting as the relay nodes, and determining, by one of the first infrastructure equipment and the one or more other infrastructure equipment acting as the relay nodes in the case that the assistance information satisfies a trigger condition, that the second infrastructure equipment should communicate with the first infrastructure equipment over a second communications path.

Abstract: A terminal device is configured to detect a failure in communicating the position assistance information, such as a failure to decrypt or an integrity protection decoding failure, and in response to detecting the failure in communicating the position assistance information to perform a position assistance information failure procedure. In one example embodiment the position assistance information failure procedure includes transmitting a message indicating the failure to the infrastructure equipment. In another example the position assistance information failure procedure includes adapting one or more communications parameters in order to recover the reception of the position assistance information.

Abstract: A communications device transmits and receives data via a wireless access interface in a mobile communications network. First resource allocation messages are received by communications devices to allocate one or more of plural communications resource elements of a host frequency range of a host carrier. Second resource allocation messages are received by reduced capability devices to allocate one or more of a first section of the communications resources within the first frequency range for preferable allocation to the reduced capability devices of a first virtual carrier, the first resource allocation messages identifying one or more of the communications resource of the host carrier allocated to the communications devices with reference to a first reference frequency and the second resource allocation messages identifying one or more communications resources of the first virtual carrier allocated to the reduced capability devices with reference to a second reference frequency within the first virtual carrier.

Abstract: A method of operating first and second terminal devices for transmitting data in a device-to-device communication mode in a wireless telecommunications system supporting communications on a first carrier operating over a first frequency band and a second carrier operating over a second frequency band. The first terminal device transmits control signalling on the first carrier and this is received by the second terminal device. The control signalling comprises an indication of that the first terminal device intends to transmit data to the second terminal device using the device-to-device communication mode on the second carrier after a carrier switch-over time. The first terminal device then proceeds to transmit data to the second terminal device on the second carrier using the device-to-device communication mode after the carrier switch-over time. The first and second terminal devices may cease communications on the second carrier after a carrier switch-back time.

Abstract: A communications device transmitting/receiving signals to/from a mobile communications network includes one or more network elements providing a wireless access interface for the communications device. The wireless access interface includes plural communications resource elements across a host frequency range of a host carrier, and a first section of the communications resources within a first frequency range for preferable allocation to reduced capability devices forming a first reduced bandwidth carrier and a second section of the communications resources within a second frequency range for preferable allocation to the reduced capability devices forming a second reduced bandwidth carrier. Each of the first and second frequency ranges is within the host frequency range. The communications device is configured with a reduced capability to receive the signals only within a frequency bandwidth less than the host frequency range and equal to at least one of the first frequency range or the second frequency range.

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.
