Abstract: A wireless telecommunications system including first and second groups of terminal devices operable to communicate with a base station via respective first and second network nodes. Each of the first and second groups of terminal devices are synchronized to communicate with the first and second network nodes, respectively, in a discontinuous mode including a repeating signalling cycle including first and second wake periods. The first wake period is a first portion of the repeating signalling cycle and the start of the first wake period is defined by a first offset value relative to the start of the repeating signalling cycle. The second wake period is a second portion of the repeating signalling cycle and the start of the second wake period is defined by a second offset value relative to the start of the repeating signalling cycle, being different from the first offset value.

Abstract: A communications system for device-to-device communications includes a group of plural communications devices, each configured to perform device-to-device communications via a wireless access interface with one or more other communications devices of the group. One of the communications devices is configured to detect interference in communications resources of the wireless access interface caused by signals transmitted by another communications device, and to provide, in response to detecting the interference, an indication of the interference to one or more of the communications device. By the communications device of the first group of communications devices detecting the interference and communicating an indication of the interference to the other members of the group, then members of the group can adapt the transmission and reception of data via the wireless access interface to avoid resources of the wireless access interface which is subject to interference.

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 can transmit and receive data via a wireless access interface provided by a mobile communications network including an infrastructure equipment for transmitting signals to or receiving signals from the communications device. The wireless access interface provides a primary carrier within a first frequency range, which forms a primary cell providing a contiguous set of communications resources across the first frequency range and providing one or more control channels for transmitting signaling message to the communications device or receiving signaling messages from the infrastructure equipment. A controller in combination with a receiver and transmitter can receive from the infrastructure equipment a signaling message identifying a nested carrier including one or more candidate channels selected from a predefined plurality of candidate channels within a second frequency range which is different to and mutually exclusive from the first frequency range.

Abstract: A communications device configured to receive data from a mobile communications network including one or more network elements providing a wireless access interface. The wireless access interface provides plural communications resource elements across a host frequency bandwidth, and includes, within the host frequency bandwidth, first communications resource elements within a first frequency bandwidth for allocation preferably to reduced capability devices to receive signals representing data transmitted by a transmitter within the first bandwidth forming a first virtual carrier, the reduced capability devices each having a receiver bandwidth greater than or equal to the first frequency bandwidth but less than the host frequency bandwidth. Communications devices of different capabilities can be allocated communications resources within different frequency ranges according to their capability, to relieve congestion on a center frequency of communications resources in which communications devices with a minimum bandwidth capability must receive communications resources for receiving down link signals.
