Abstract
The controller circuitry is configured to identify one of the plurality of different position assistance information for use by the terminal device to identify a position of the terminal device, and 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. The position assistance information is identified in accordance with a permission allocated to the terminal device. By providing system information which is unencrypted and other system information which is encrypted, conditional access to the position assistance information can be provided in which a lowest level of position assistance information can provide the least level of position estimation accuracy.
