Abstract: A terminal device is configured to detect a failure in communicating the position assistance information, such as a failure to decrypt or an integrity protection decoding failure, and in response to detecting the failure in communicating the position assistance information to perform a position assistance information failure procedure. In one example embodiment the position assistance information failure procedure includes transmitting a message indicating the failure to the infrastructure equipment. In another example the position assistance information failure procedure includes adapting one or more communications parameters in order to recover the reception of the position assistance information.

Abstract: A method of transmitting data from a first communications terminal to one or more second communications terminals includes receiving from an infrastructure equipment forming part of a wireless communications network an indication identifying a predetermined pattern of communications resources of a wireless access interface. The wireless access interface provides plural communications resources divided into time divided units. The method also includes transmitting the data in some or all of the predetermined pattern of communications resources to one or more of the second communications terminals in accordance with device to device communications. The predetermined pattern of communications resources is one of plural patterns of communications resources of the wireless access interface for plural of the time divided units. The plural patterns of communications resources are predetermined for a reduction in latency when transmitting the data from the first communications terminal and/or reducing in signalling overhead required to transmit the data.
