摘要： A communications device acting as a rely device is configured to transmit a buffer status report message indicating that the buffer is storing data received from the infrastructure equipment for transmission to a remote communications device, when predetermined conditions are satisfied or a trigger event occurs so that the transmission of the data to the remote communications device can make more efficient use of communications resources to transmit the data or the remote communications device receives the data when the remote communications device is in a state in which it should receive the data, for example when not in a reduced power state.

摘要： The system supports a virtual carrier mode of operation in which downlink communications are made by a base station using a radio interface that spans a system frequency bandwidth while a terminal device is configured to receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth. The system supports terminal devices in both a radio resource control connected mode and a radio resource control idle mode. When there is to be a change in system information the base station transmits to the terminal device an indication that updated system information is to be broadcast by the base station and this indication is received by the terminal device while in the connected mode. Before seeking to acquire the updated system information, the terminal device transitions from the connected mode to the idle mode.

摘要： An infrastructure equipment that transmits a radio network identifier to a communications device for identifying the communications device when allocating communications resources of the wireless access interface for transmitting downlink data to the communications device. After the communications device has entered an inactive connected state, the infrastructure equipment transmits control signals including the radio network identifier for allocating communications resources of the wireless access interface for the communications device to receive downlink data, determine whether the communications device is still within a radio coverage area of the infrastructure equipment, and if the communications device has left the coverage area, transmit an indication to the one or more other infrastructure equipment via the inter-connecting interface to trigger a process for transmitting downlink data to the communications device from the one or more other infrastructure equipment.

摘要： A method of transmitting system information in a mobile communications network, the network comprising a base station operable to provide a cell to communicate wirelessly with a plurality of mobile terminals and a mobile terminal of the plurality of mobile terminals, the mobile terminal being operable to communicate with the base station. The method comprises periodically transmitting essential system information “ESI” to the plurality of mobile terminals, the ESI comprising system information for using the cell provided by the base station; transmitting additional system information “ASI” to the mobile terminal, the ASI comprising system information for using one or more services provided by the cell. In the event that it is determined that the base station is overloaded, the method further comprises transmitting a service notification that the cell is currently unable to provide the one or more services.

摘要： A wireless telecommunications system in which downlink communications are made using a radio interface that spans a system frequency bandwidth (host carrier) and supports at least some communications from a base station to least some terminal devices within a plurality of restricted frequency bands (virtual carriers) which are narrower than and within the system frequency bandwidth. A terminal device conveys an indication of its identity, e.g. an IMSI, to the base station during an initial connection procedure as the terminal device seeks to access the radio interface. The terminal device and the base station both determine a selected restricted frequency band from among the plurality of restricted frequency bands based on the identity of the terminal device in the same way. Thus the terminal device and the base station select the same restricted frequency band and can accordingly configure their respective transceivers to allow for downlink communications between them within the selected restricted frequency band.

摘要： A communications device includes a transmitter configured to transmit signals to one or more other communications devices via a wireless access interface, the one or more communications devices configured to perform device-to-device communications. A receiver is configured to receive signals from the one of the other communications devices via the wireless access interface, and a controller controls the transmitter and receiver to transmit or to receive the signals via the wireless access interface to transmit or to receive data represented by the signals. The wireless access interface provides a scheduling region including plural predetermined sections of communications resources, and plural sections of shared communications resources. Transmission of a scheduling assignment message in a section of the scheduling region informs other devices of a group that a communications device will transmit signals representing data in a corresponding section of the shared communications channel.
