    Abstract: A method of operating a terminal device in a wireless telecommunications system is disclosed. The terminal device is configured to selectively switch between an active operating mode and a reduced-power operating mode. The method comprises communicating with a network entity to exchange a block of data between the terminal device and the network entity while the terminal device is in the active operating mode. The method further comprises determining when communications associated with the exchange of the block of data are complete, and in response to determining communications associated with the exchange of the block of data are complete, switching from the active operating mode to the reduced-power operating mode.

    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 method of evaluating whether to handover a terminal device from communicating with a first network infrastructure element associated with a first communication cell to communicating with a second network infrastructure element associated with a second communication cell in a wireless telecommunications system. The method includes establishing an indication of radio conditions associated with a path between the terminal device and the first network infrastructure element; and establishing an indication of a second measurement of radio conditions associated with a communication path between the terminal device and the second network infrastructure element; and determining whether to handover the terminal device from communicating with the first network infrastructure element to the second network infrastructure element based on a comparison of the indication of the first measurement of radio conditions and the indication of the second measurement of radio conditions.

    Abstract: A communications device acting as a relay device is configured to communicate with a transmitting node and a receiving node. The communications device acting as the relay is configured to receive signals representing protocol data units formed from one or more service data units via a first wireless access interface from the transmitting node according to a first automatic repeat request process for transmission to the receiving node, transmit signals representing the received protocol data units via a second wireless access interface to the receiving node according to a second automatic repeat request process, and store the protocol data units received by the receiver circuitry for transmission to the receiving node according to the second automatic repeat request process.

    Abstract: A method for use in a mobile communications network that includes a plurality of infrastructure equipment each providing wireless connectivity within at least one cell, and a communications device configured to communicate wirelessly with at least a first infrastructure equipment including use of a radio bearer. The first infrastructure equipment performs the method including determining that there is a requirement to alter data handling resources allocated for handling the radio bearer in one or both of the first infrastructure equipment and the communications device, re-establishing, in response to the determination, its radio link control protocol layer, transmitting a reconfiguration message to the communications device to effect re-establishment of its radio link control protocol layer, and adding a new bit in the header of data packets transmitted to the communications device for a predetermined time after re-establishment of the radio link control protocol layer of the first infrastructure equipment.

    Abstract: A method of operating a terminal device to perform measurement event evaluation for measurement reporting in respect of a downlink carrier in a wireless telecommunications system. The method includes determining that measurement event evaluation for the downlink carrier should be undertaken. Measurements of a parameter associated with radio channel conditions for frequency resources used by the downlink carrier are obtained during an evaluation period beginning at a start time. The extent to which the downlink carrier is being transmitted during the evaluation period is also established. Whether or not to send a measurement report to network infrastructure equipment is then evaluated by taking account of both the measurements of the parameter during the evaluation period and the extent to which the downlink carrier is being transmitted during the evaluation period.
