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 wireless telecommunications system including first and second terminal devices operable to communicate with one another in a synchronized device-to-device manner. The second terminal device is operable to selectively achieve synchronization for receiving data transmissions from the first terminal device using direct synchronization signalling transmitted by the first terminal device or indirect synchronization signalling transmitted by another network entity, such as a base station. The second terminal device is configured to preferentially seek indirect synchronization over direct synchronization, unless the second terminal device detects synchronization signalling transmitted by the first terminal device is associated with a predefined characteristic that indicates the synchronization signalling transmitted by the first terminal device is high priority synchronization signalling, in which case the second terminal device is configured to preferentially seek synchronization using the high priority direct synchronization signalling from the first terminal device over indirect synchronization signalling transmitted by the other network entity.

Abstract: Techniques for controlling updating of information stored on a device, the information including information of a first type and information of a second type. The techniques include determining, using at least one processor, when a first item of information of the first type and a second item of information of the second type are to be updated, wherein the second item of information is to be updated more frequently than the first item of information; and causing the device to update the first and second items of information in accordance with the determination at least in part by wirelessly communicating with at least one other device.
