摘要： A method of communicating data between a radio network infrastructure and a terminal device in a wireless telecommunications network. The method comprises establishing at a radio network infrastructure element there is data available for communication between the radio network infrastructure and the terminal device and transmitting a paging message for the terminal device from the radio network infrastructure element. The paging message comprises an indication of an identifier for the terminal device and an indication of a network allocated resource for use in subsequently communicating the data between the radio network infrastructure element and the terminal device. In response to receiving the paging message the terminal device transmits to the radio network infrastructure element a paging response indicating the terminal device received the paging message, after which the data is communicated between the radio network infrastructure element and the terminal device using the network allocated resource.

摘要： A method of operating a communications device to provide a ranging-based service which uses a proximity between the communications device and at least one other communications device is provided. The method comprises transmitting a discovery signal to the at least one other communications device; receiving a response signal from the at least one other communications device determining an estimate of an angle-of-arrival of the response signal to the communications device and an estimate of a distance between the communications device and the at least one other communications device from the response signal; using the estimate of the angle-of-arrival of the response signal to the communications device and the estimate of the distance between the communications device and the at least one other communications device to initiate the ranging-based service between the communications device and the at least one other communications device.

摘要： A method for operating a communications device is provided. The communications device is configured to transmit uplink signals to and/or to receive downlink signals from a non-terrestrial infrastructure equipment forming part of a non-terrestrial network, NTN, and to transmit uplink signal to and/or to receive uplink signals from a terrestrial infrastructure equipment forming part of a terrestrial network, TN. The method comprises communicating with the non-terrestrial infrastructure equipment via one of a plurality of spot beams, each of the spot beams providing a first wireless access interface for transmitting the uplink signals to and/or receiving the downlink signals from the non-terrestrial infrastructure equipment within a coverage region formed by the each of the spot beams, and communicating with the terrestrial infrastructure equipment via a second wireless access interface provided by the terrestrial infrastructure equipment.

摘要： A method of performing cell reselection by a wireless communications device comprises measuring a signal strength of radio signals received from a serving cell, determining whether the signal strength of the signals received from the serving cell is lower than a first predetermined signal strength threshold, if the signal strength is lower than the first predetermined signal strength threshold measuring a signal strength of a neighbor cell operating on the same frequency as the serving cell to generate signal strength measurements at a first rate, and in accordance with the signal strength measurements of the neighbor cell generated at the first rate determining whether to reselect to the neighbor cell.

摘要： A plurality of communications nodes are configured to form a wireless backhaul network to communicate data from a core network of the wireless communications network for transmitting to one or more communications devices or to communicate data to the core network received from the one or more communications devices. At least a first and a second of the plurality of communications nodes are donor communications nodes formed from radio network infrastructure equipment having a physical connection to the core network. According to example embodiments, a migrating communications node determines that it should migrate from a first attachment point in the wireless backhaul network in which the migrating node communicates the data to or from the core network via the first donor communications node. The term “attachment point” is used to express a link of a communications node to other nodes in the backhaul network. The radio communications links are formed to communicate data to and from the core network via donor communications nodes and may be also via one or other nodes according to an established hierarchy of the wireless backhaul network. The migrating communications node determines a second attachment point in the wireless backhaul network to which the migrating communications node should attach to the wireless backhaul network to communicate the data to or from the core network, and the migrating communications node migrates from the first attachment point to the second attachment point. The second attachment point is determined by biasing a selection of the second attachment point either to provide the migrating communications node with radio communications resources from the first donor communications nodes when attached to the wireless backhaul network at the second attachment point as an intra-donor migration, or to provide the migrating communications node with radio communications resources from the second donor communications node when attached to the wireless backhaul network at the second attachment point as an inter-donor migration.

摘要： A communications device is provided. The communications device comprises transceiver circuitry configured to transmit signals to and/or to receive signals from a first cell of a wireless communications network, and controller circuitry. The controller circuitry is configured in combination with the transceiver circuitry to determine that the communications device is within a coverage area of a cell of a wireless communications network, to receive a downlink signal from the cell of the wireless communications network, the downlink signal indicating whether or not the communications device can connect to the cell in order to transmit signals to and/or receive signals from the wireless communications network, and to detect, based on the downlink signal, whether the wireless communications network is an on-demand network and/or a temporary network.
