    摘要: A method for operating an infrastructure equipment forming part of a wireless communications network is provided. The wireless communications network comprises a base station and a non-terrestrial network part, the non-terrestrial network part transmitting one or more spot beams to provide a wireless access interface for transmitting signals to and receiving signals representing data from a communications device within a coverage region of a cell or one of the spot beams, the spot beam forming a cell. The method comprises transmitting, to the communications device, an indication of a first condition to be met before the communications device should transmit assistance information to the infrastructure equipment, receiving the assistance information from the communications device upon the first condition being met, determining, based on the assistance information, that a cell change of the communications device should be initiated, and initiating the cell change of the communications device.

    摘要: A wireless telecommunication system includes base stations for communicating with terminal devices. One or more base stations support a power boost operating mode in which a base station's available transmission power is concentrated in a subset of its available transmission resources to provide enhanced transmission powers as compared to transmission powers on these transmission resources when the base station is not operating in the power boost mode. A base station establishes an extent to which one or more base stations in the wireless telecommunications system support the power boost operating mode conveys an indication of this to a terminal device. The terminal device receives the indication and uses the corresponding information to control its acquisition of a base station of the wireless telecommunication system, for example by taking account of which base stations support power boosting and/or when power boosting is supported during a cell attach procedure.

    摘要: A terminal device for use in a wireless telecommunications system comprises a transceiver to perform wireless communication with a base station and to obtain system information defining communication parameters from system information data received from that base station; system information storage; and a controller to detect whether the system information storage already holds at least some of the system information applicable to a newly communicating base station and to control the transceiver to obtain any portions of the system information not already held by the terminal device, in which: the system information comprises a plurality of system information blocks; and the controller is configured to detect parts of a system information block stored by the system information storage which are applicable to the newly communicating base station and to obtain other parts of that system information block as a partial system information block from the newly communicating base station.

    摘要: A wireless telecommunications system including a base station and terminal device, supporting a virtual carrier mode with downlink communications made by the base station using a radio interface spanning a system frequency bandwidth while the terminal device can receive at least some communications from the base station within a restricted subset of transmission resources selected from within the system frequency bandwidth providing a restricted bandwidth downlink. The terminal device can measure channel conditions across the system frequency bandwidth and transmit corresponding measurement reports to the base station. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be aperiodic while measurement reports for transmission resources including the restricted bandwidth downlink channel may be periodic. Measurement reports for transmission resources not including the restricted bandwidth downlink channel may be based on a subset of the channel condition measurements selected because they are associated with relatively poor channel conditions.
