Abstract: A network infrastructure equipment establishes a configuration of radio resources within a second frequency band for use by a terminal device for communications with network infrastructure equipment based on a first radio access technology and communicates an indication of that to the terminal device. The terminal device establishes a configuration of radio resources for use by the terminal device for communications based on a second radio access technology and determines if there is any overlap in radio resources configured for use by two different radio access technologies, and if so communicates an indication of that to the network infrastructure equipment. In response the network infrastructure equipment establishes a replacement configuration of radio resources for communications with the terminal device based on the first radio access technology that avoids the radio resources indicated as subject to overlap, and transmits an indication of the replacement configuration to the terminal device.

Abstract: A method of operating a terminal device to perform measurement event evaluation for measurement reporting in respect of a downlink carrier operating in a wireless telecommunications system. The method comprises determining that measurement event evaluation for the downlink carrier should be undertaken beginning at a start time. Measurements of a parameter, such as a reference signal received power, associated with radio channel conditions for frequency resources used by the downlink carrier are obtained during an evaluation period beginning at the start time. The extent to which the downlink carrier is being transmitted during the evaluation period is also established. Whether or not to send a measurement report to network infrastructure equipment is then evaluated by taking account of both the measurements of the parameter during the evaluation period and the extent to which the downlink carrier is being transmitted during the evaluation period. A measurement report is sent by the terminal device to the network infrastructure equipment depending on the outcome of the evaluation.

Abstract: A communications device is configured to receive data from a wireless access interface transmitted by a mobile communications network. The wireless access interface provides a plurality of communications resource elements within a system bandwidth providing a host frequency range of a host carrier and reserved communications resources for preferable allocation to reduced capability devices, the reserved communications resources forming a virtual carrier. In each of a plurality of time divided units, the wireless access interface provides a shared channel of communications resources and a control channel formed within the communications resources of the system bandwidth of the host frequency range for communicating resource allocation messages to communications devices. The resource allocation messages allocate the communications resources of the shared channel to the communication devices within the system bandwidth and allocate the reserved communications resources to the reduced capability devices. The reserved communications resources include one or more communications resources which are not allocated for transmitting data to the reduced capability devices. A reduced capability device receives a resource allocation message from the control channel, allocating resources within the reserved communications resources of the virtual carrier for receiving data, determines the communications resources of the reserved communications resources which will contain signals representing the data from the communications resources allocated within the reserved communications resources by the received resource allocation message and excluding any of the one or more communications resources which are not allocated for transmitting data and receives the data from the determined communications resources of the reserved communications resources of the virtual carrier.

Abstract: A communications device to transmit data to a mobile communications network includes one or more network elements providing a wireless access interface for communication. The communications device includes a controller controlling a transmitter to transmit a random access message to a first network element via a random access channel of the wireless access interface common to one or more other communications devices, to receive in response an acknowledgement indicating an allocation of communications resources of a shared up-link channel for the communications device to transmit signals to the mobile communications network, or a negative acknowledgment indicating the communications device has not been allocated communications resources of the shared up-link channel. After detecting random access failure conditions by the controller, the controller in combination with the transmitter re-transmits the random access message one or more times, with a variable delay greater than or equal to a delay of a previous re-transmission.

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, 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.

Abstract: A wireless telecommunications system comprises a base station and a terminal device. The system supports a virtual carrier mode of operation in which downlink communications are made by the base station using a radio interface that spans a system frequency bandwidth while the 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 wireless telecommunications 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. The terminal device then seeks to acquire updated system information while in the idle mode. The base station restricts the transmission of user-plane data to the terminal device until the terminal device re-enters connected mode. Transitioning to idle mode to acquire system information can help to address issues associated with managing the communication of both system information and user-plane data using the restricted subset of transmission resources.
