Abstract: A wireless telecommunications system supports a virtual carrier operation mode in which downlink communications are made by a base station while a terminal device can receive at least some communications from the base station within a restricted subset of transmission resources, and supports terminal devices in a radio resource control connected mode and 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, the indication 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, and then seeks to acquire updated system information. The base station restricts transmission of user-plane data to the terminal device until the terminal device re-enters the connected mode.

Abstract: A method of operating a terminal device in a wireless telecommunications system, wherein the terminal device is configured to selectively switch between an active operating mode and a reduced-power operating mode, wherein 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; 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. The terminal device supports a protocol stack comprising a physical, PHY, layer, a medium access control, MAC, layer, and a radio link control, RLC, layer, and determining when communications associated with the exchange of the block of data are complete and the device should switch to the low-power mode is performed by the radio link control, RLC, layer.

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: A method of transmitting data from a first communications terminal to one or more second communications terminals includes receiving from an infrastructure equipment forming part of a wireless communications network an indication identifying a predetermined pattern of communications resources of a wireless access interface. The wireless access interface provides plural communications resources divided into time divided units. The method also includes transmitting the data in some or all of the predetermined pattern of communications resources to one or more of the second communications terminals in accordance with device to device communications. The predetermined pattern of communications resources is one of plural patterns of communications resources of the wireless access interface for plural of the time divided units. The plural patterns of communications resources are predetermined for a reduction in latency when transmitting the data from the first communications terminal and/or reducing in signalling overhead required to transmit the data.

Abstract: A wireless telecommunications system including: a controller; a first base station and a second base station; and a terminal device operable to communicate with the first base station over a first radio path and to communicate with the second base station over a second radio path. The controller is configured to select one of the first base station and the second base station to act as a serving base station for the terminal device based on measurements of beacon signalling transmitted by the terminal device, wherein the measurements provide an indication of radio channel conditions associated with the first radio path and the second radio path.

Abstract: A communications terminal includes a controller configured in combination with a transmitter and receiver when in a connected mode to control the receiver to operate in accordance with a discontinuous reception, DRX, state, to measure, when in a re-selection mobility management mode of the DRX state, signals received by the receiver from any of one or more infrastructure equipment, and to select, based on the measured signals received by the receiver from any of the one or more infrastructure equipment, one of the one or more infrastructure equipment from which to receive signals transmitted on a downlink. When in a network controlled mobility management mode of the DRX state after predetermined conditions have been satisfied, the controller is configured to switch to the re-selection mobility management mode of the DRX state.

Abstract: 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, 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 base station select the same restricted frequency band and can accordingly configure their respective transceivers to allow downlink communications between them within the selected restricted frequency band.
