Abstract: A relay device configured to communicate with a terminal device of the network and with a base station of the network. The relay device comprises transmitter circuitry, receiver circuitry and controller circuitry. The controller circuitry is configured in combination with at least the transmitter circuitry: to select a maximum transmission power to be used by the terminal device for communicating with the relay device, wherein the identified maximum transmission power is based on link information relating to one or both of the link between the relay device and the base station and the link between the relay device and the terminal; to notify the communication device of the selected maximum transmission power for the terminal to select an actual transmission power and to transmit signals to the relay device at a power that is no more than the maximum transmission power.

Abstract: A method allocating resources in a mobile telecommunications system including a base station, one or more terminals, and one or more infrastructure nodes configured to communicate via a wireless interface allocated for successive time periods. The method includes: obtaining measurements that relate to a link between a first of the terminals and one of the infrastructure nodes; identifying communications between the first terminal and the one infrastructure node as delay-sensitive communications; identifying, based on the obtained measurements and identification of the communications between the first terminal and the one infrastructure nodes as delay-sensitive communications, resources to allocate for the first terminal to communicate with one or more of the infrastructure nodes, selected from two or more of the time periods; and allocating the identified resources for the first terminal to communicate with the one or more of the infrastructure nodes during the two or more time periods.

Abstract: A wireless telecommunications system including a base station and terminal device, supporting a virtual carrier mode with downlink communications made by the base station using a radio interface spanning a system frequency bandwidth while the terminal device can receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth providing a restricted bandwidth downlink. The terminal device can measure channel conditions across the system frequency bandwidth and transmit corresponding measurement reports to the base station. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be aperiodic while measurement reports for transmission resources including the restricted bandwidth downlink channel may be periodic. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be based on a subset of the channel condition measurements selected because they are associated with relatively poor channel conditions.

Abstract: A communications system communicating data to/from a communications terminal includes plural wireless communications networks to transmit/receive signals to/from the communications terminal via wireless access interfaces. The communications terminal receives from an access server selection information for selecting one of the wireless communications networks, for transmitting or receiving the data in accordance with the selection information in combination with one or more determined measurements of the wireless access interface of the wireless communications networks. The access server includes an indication of a preferred communications characteristic for transmitting or receiving the signals representing the data, and in accordance with the preferred communications characteristic the communications terminal adapts the determined measurements and selects one of the wireless communications networks which most closely satisfy the preferred communications characteristic in accordance with the adapted-determined measurements.

Abstract: A method for use in a wireless telecommunications network, the method including: when a secondary base station exhausts a supply of unique parameter sets used in security ciphering of received split radio bearers, the secondary base station sends a notification to a master base station of a requirement to alter data handling resources allocated for handling split radio bearers received from the secondary base station in one or both of the master base station and a terminal device; and the master base station, in response to the notification, operating to effect an alteration in the said data handling resources.

Abstract: A method determining indication of an occupancy level in a mobile communications system including a base station to communicate with a mobile communications device via a wireless interface provided by a first frequency channel allocated to mobile networks communications for the mobile communications system and by a shared channel which can be shared by the mobile communications system and by other wireless communications systems. The method includes: a mobile communications device: measuring, for each of plural first time periods within a second time period, a channel utilization on the shared channel; determining channel occupancy states for the shared channel for each of the first time periods based on the measured channel utilization; and determining an indication of an occupancy level for the shared channel for the second time period, the indication of an occupancy level determined based on the occupancy states for the shared channel for each first time period.

Abstract: A method of transmitting/receiving data between a communications device and a mobile communications network including a wireless access interface providing communications resources within a system bandwidth and in time divided units allocated to communications devices of first and second types having different capabilities. The method generates, at the communications device, a random access message, by selecting a sequence from a predetermined set of sequences, which have been allocated to the communications devices of the second type and transmitting the random access message from the communications device to the wireless communications network, and in response to the random access message, receives a random access response at the communications device transmitted according to the capability of the communications device of second type, the random access message being recognized as from a communications device of second type from the selected one of the predetermined sequences allocated to the communications devices of second type.
