Claim of US Patent No. 11,071,084


1. A terminal device for use in a wireless telecommunications network, the terminal device comprising:wireless communications receiver circuitry configured to receive signals from the infrastructure equipment via a wireless access interface provided by the infrastructure equipment,
position detection receiver circuitry configured to receive, from a satellite or non-satellite signal emitting device, a radio signal from which measurements can be used to assist in determining a position of the terminal device, and
controller circuitry configured tocontrol the wireless communications receiver circuitry to detect one or more system information blocks carrying position assistance information transmitted from the infrastructure equipment, the position assistance information providing information which can be used to assist in determining the position of terminal device, and
control the position detection circuitry to estimate the position of the terminal device by combining the identified position assistance information with the radio signal received by the position detection receiver circuitry,

wherein the controller circuitry is configured with the wireless communications receiver circuitry toreceive from the infrastructure equipment, prior to the position assistance information changing, an indication of relative risk that the position assistance information will change, and
prior to the position assistance information changing, and in response to the indication of the relative risk that the position assistance information will change, 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.
