Abstract: The invention relates to cell re-selection as a consequence of UE mobility in a scenario where coverage enhancement (CE) is employed for multiple repetitions of messages communicated on a wireless link between the UE and the network, and where a CE policy defines a repetition level. Accordingly, a communication device (130) receives at least one downlink control message (6031) from a base station (112, 112-1) of a source cell (181) of a network (100), the at least one downlink control message (6031) being indicative of access restrictions of a plurality of candidate cells (182, 183) of the network (100); more particularly, the at least one downlink control message (6031) is indicative, for each candidate cell (182, 183) of the plurality of candidate cells (182, 183), of at least one respective regulated repetition level. Based on the at least one downlink control message (6031), the communication device (130) selects a target cell (182, 183) from the plurality of candidate cells (182, 183); and communication between the communication device (130) and a base station (112, 112-2, 112-3) of the target cell (182, 183) is performed.

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.

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.
