US 2019/0357166 A1 · Synchronization Signal Selection

Abstract

A wireless device (18) is configured for selecting a synchronization signal to use as a reference for device-to-device, D2D, communication. The wireless device (18) is configured to receive a multi-level synchronization signal (28) for which prioritization rules at the wireless device (18) define multiple priority levels. The wireless device (18) is also configured to select, from among multiple received synchronization signals including the multi-level synchronization signal (28), a synchronization signal to use as a reference for D2D communication, based on priority levels defined for the received synchronization signals and based on a radio resource (32) on which the wireless device (18) received the multi-level synchronization signal (28).

A method, performed by a wireless device, for selecting a synchronization signal to use as a reference for device-to-device (D2D) communication, the method comprising:

receiving a multi-level synchronization signal for which prioritization rules at the wireless device define multiple priority levels;
and
selecting, from among multiple received synchronization signals including the multi-level synchronization signal, a synchronization signal to use as a reference for D2D communication, based on priority levels defined for the received synchronization signals and based on a radio resource on which the wireless device received the multi-level synchronization signal.

A wireless device for selecting a synchronization signal to use as a reference for device-to-device (D2D) communication, the wireless device comprising:

wireless communication circuitry;
and
processing circuitry whereby the wireless device is configured to:
receive a multi-level synchronization signal for which prioritization rules at the wireless device define multiple priority levels;
and
select, from among multiple received synchronization signals including the multi-level synchronization signal, a synchronization signal to use as a reference for D2D communication, based on priority levels defined for the received synchronization signals and based on a radio resource on which the wireless device received the multi-level synchronization signal.
