Abstract: 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.

Abstract: A method determining indication of an occupancy level in a mobile communications system including a base station to communicate with a mobile communications device via a wireless interface provided by a first frequency channel allocated to mobile networks communications for the mobile communications system and by a shared channel which can be shared by the mobile communications system and by other wireless communications systems. The method includes: a mobile communications device: measuring, for each of plural first time periods within a second time period, a channel utilization on the shared channel; determining channel occupancy states for the shared channel for each of the first time periods based on the measured channel utilization; and determining an indication of an occupancy level for the shared channel for the second time period, the indication of an occupancy level determined based on the occupancy states for the shared channel for each first time period.

Abstract: An infrastructure equipment for providing a wireless backhaul for another infrastructure equipment in a wireless communications network comprises a receiver configured to receive, from the other infrastructure equipment acting as a relay, uplink data transmitted by a communications device, a transmitter configured to transmit to the infrastructure equipment acting as a node via the wireless access interface, and a controller. The controller is configured to control the transmitter and receiver to establish a connection with the other infrastructure equipment, the connection providing the wireless backhaul for the transmission of data from the communications device to a core network of the wireless communications network via the other infrastructure equipment, and to transmit in a message on the downlink of the wireless access interface an indication of whether the other infrastructure equipment is permitted to transmit a request while in the connected mode.

Abstract: A terminal device configured to receive a radio signal from which measurements can be used to assist in determining a position of the terminal device. The terminal device detects one or more system information blocks carrying position assistance information transmitted from the infrastructure equipment and estimates the position of the terminal device by combining the identified position assistance information with the radio signal received by the position detection receiver circuitry. Furthermore the terminal device receives from the infrastructure equipment an indication of relative risk that the position assistance information will change, and in response to the indication of the relative risk that the position assistance information will change to adapt the receiving of the one or more system information blocks to receive an updated version of the position assistance information in accordance with the relative risk.

Abstract: A method of evaluating whether to handover a terminal device from communicating with a first network infrastructure element associated with a first communication cell to communicating with a second network infrastructure element associated with a second communication cell in a wireless telecommunications system. The method includes establishing an indication of radio conditions associated with a path between the terminal device and the first network infrastructure element; and establishing an indication of a second measurement of radio conditions associated with a communication path between the terminal device and the second network infrastructure element; and determining whether to handover the terminal device from communicating with the first network infrastructure element to the second network infrastructure element based on a comparison of the indication of the first measurement of radio conditions and the indication of the second measurement of radio conditions.
