Abstract: Schemes for supporting device-to-device, D2D, communications between terminal devices in a wireless telecommunication system. A network entity, e.g. a base station, establishes a set pool of radio resources to be reserved for use for D2D communications and communicates an indication of these resources to terminal devices. On an ongoing basis the network entity monitors the extent to which the set of radio resources reserved for D2D communications is being used, for example based on feedback received from terminal devices or its own measurements. If it is determined the set of radio resources reserved for D2D communications is being under-utilized or over-utilized, the network entity may establish an updated set of radio resources to be used for D2D communications, and communicate this to the terminal devices. Thus a mechanism is provided for dynamically adjusting the size of a set of resources available for D2D communications in response to changing resource utilization.

Abstract: A communications system is provided, comprising one or more infrastructure equipment forming part of a wireless communications network, and a communications device. The communications device is configured to transmit or receive signals via a wireless access interface provided by the wireless communications network to or from a peer terminal in the wireless communications network with one or more pre-authorised quality of service, PAQ, flows, at least one of the PAQ flows currently being inactive. One or more of the infrastructure equipment are configured to receive an indication that the communications device is preparing to transmit or receive data with the PAQ flows to or from the one or more of the infrastructure equipment.

Abstract: A method of operating a terminal device and a base station in a wireless telecommunications system to communicate with one another using a primary component carrier operating on radio resources within a first frequency band and a secondary component carrier operating on radio resources within a second frequency band. The terminal device makes measurements of radio usage in the second frequency band, e.g. by other devices which are not part of the wireless telecommunications system but which can also use radio resources within the second frequency band. The terminal device transmits an indication of the measurements to the base station, and on the basis if this the base station establishes a configuration setting for the secondary component carrier, for example in terms of frequency resources to use for the secondary component carrier. The configuration setting is associated with a validity period during which the base station communicates data to the terminal device using the primary component carrier and the secondary component carrier operating in accordance with its configuration setting. When the validity period expires, the terminal device again measures and reports on radio usage so the base station can determine an updated configuration setting for the secondary component carrier that takes account of any changes in radio usage during the validity period.

Abstract: A communications device and method for performing device-to-device communications. The method includes receiving, from a mobile communications network, an indication of whether a communications device can use at least one of first communications resources of a wireless access interface for performing device-to-device communications in accordance with a first mode of operation or second communications resources of the wireless access interface for performing device to device communications in accordance with the second mode of operation, and depending on the indication provided by the mobile communications network and the configuration of the first communications resources and/or the second communications resources, transmitting signals to the one or more other communications devices via the first communications resources or transmitting signals to the one or more other communications devices via the second communications resources in accordance with the second mode of operation using the device to device communications protocol.

Abstract: A method includes determining a parameter of a coverage enhancement policy employed by a communication system. The method also includes setting a timing configuration (371-373, 391-393, 605, 606) of a discontinuous reception cycle (370-2, 370-3) employed by a terminal (101) of the communication system depending on the parameter. The method also includes communicating a paging signal in accordance with the timing configuration (371-373, 391-393, 605, 606) of the discontinuous reception cycle (370-2, 370-3) and the coverage enhancement policy.

Abstract: A wireless telecommunications system including a terminal device; first infrastructure equipment operable to communicate with the terminal device using a first radio access technology (RAT) and second infrastructure equipment operable to communicate with the terminal device using a second RAT. During a handover procedure for handover from the first infrastructure equipment as a source master infrastructure equipment to a third infrastructure equipment as a target master infrastructure equipment, the second infrastructure equipment is operable to communicate with the third infrastructure equipment using an interface associated with the second RAT so as to allow information necessary for completing the handover to be exchanged between the first infrastructure equipment and the third infrastructure equipment via the second infrastructure equipment.
