Abstract: A method of communicating data in a telecommunications system comprising a base station and a plurality of terminals operable to communicate data to and from the base station. The system is configured to transmit downlink signals using downlink resources in a frequency band and in a first time period and the method comprises, upon identification of uplink data to be transmitted by a first terminal of the plurality of terminals, dynamically selecting a set of resources for transmitting the uplink data, wherein selecting the set of resources comprises selecting a subset of the frequency band and a subset of the time period of the downlink resources, the selected set of resources being based on the subset of the frequency band and the subset of the time period.

Abstract: The present application relates to a method for operating a terminal device (17) in a cellular mobile communication network (10). The cellular mobile communication network (10) comprises a first base station (11) using a first radio resource, and a second base station (12, 13) using a second radio resource. The terminal device (17) comprises a first transceiver unit (25) for communicating via the first radio resource and a second transceiver unit (26) for communicating via the second radio resource. According to the method, a radio resource control information for the second radio resource is determined and received at the terminal device (17) via the first transceiver unit (25). As defined by the radio resource control information, user data communication (19) between the second base station (12) enter the terminal device (17) is established via the second transceiver unit (26). The first transceiver unit (25) is set in an idle mode.

Abstract: An infrastructure equipment of a wireless communications network is configured when data is to be transmitted to a communications device, to transmit a control message providing an indication that the infrastructure equipment intends to transmit a paging message to the communications device, and providing an indication of communications resources of a shared channel on which the paging message is to be transmitted. The paging message includes an indication that the communications device should establish a connection with the infrastructure equipment to receive the data from the infrastructure equipment. The communications device is one of a group of communications devices, configured to receive the control message, sub-divided into sub-groups of communications devices. The control message can include an indication of one of the sub-groups which should receive the paging message to be transmitted in the communications resources of the shared channel identified by the control message.

Abstract: A method of operating first and second terminal devices for transmitting data in a device-to-device communication mode in a wireless telecommunications system supporting communications on a first carrier operating over a first frequency band and a second carrier operating over a second frequency band. The first terminal device transmits control signalling on the first carrier and this is received by the second terminal device. The control signalling comprises an indication of an allocation of radio resource blocks on the second carrier to be used for transmitting user-plane data from the first terminal device to the second terminal device. The first terminal device then proceeds to transmit the user-plane data to the second terminal device on the second carrier using the radio resource blocks on the second carrier identified by the control signalling. The control signalling may also provide an indication of an allocation of radio resource blocks on the first carrier to be used for transmitting user-plane data to the second terminal device.

Abstract: Methods of communicating in a wireless telecommunications system comprising a communications device, a master cell group comprising one or more infrastructure equipment of a first type and a secondary cell group comprising one or more infrastructure equipment of a second type, the communications device being in a coverage area of one of the infrastructure equipment of the first type and a coverage area of at least one of the infrastructure equipment of the second type, wherein the communications device is configured to transmit signals to and receive signals from the infrastructure equipment of the first type in accordance with a first communications protocol and to transmit signals to and receive signals from the at least one infrastructure equipment of the second type in accordance with a second communications protocol, the second communications protocol being different to the first communications protocol. A method according to a first example embodiment of the present disclosure comprises establishing a measurement of radio conditions associated with a first communications path between the communications device and the infrastructure equipment of the first type, determining that the first communications path is not appropriate for use by the communications device, transmitting a failure message from the communications device to one of the infrastructure equipment of the second type via a second communications path, the failure message providing information regarding the determination that the first communications path is not appropriate for use by the communications device, receiving at the communications device a signal comprising a reconfiguration message from the one of the infrastructure equipment of the second type via the second communications path, and establishing, using the reconfiguration message, signals to be transmitted by the communications device and signals to be received by the communications device.

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 retransmits the random access message one or more times, with a variable delay greater than or equal to a delay of a previous re-transmission.
