Systems, methods and devices for cellular synchronization references
First Claim
1. A system for wireless transmissions using a prioritized timing reference comprising:
- a global navigation satellite system (GNSS) receiver;
a wireless transceiver configured to communicate with a first device;
a processor configured to;
receive a prioritized list of synchronization sources including GNSS and evolved Node B (eNB);
select a timing reference based at least in part on a ranking system of the synchronization sources; and
synchronize transmission timing to the timing reference of the synchronization source.

Abstract
Cellular (e.g., LTE or UMTS) and global navigation satellite system (GNSS) based technologies can provide ubiquitous and seamless synchronization solution for LTE-based vehicle to everything (V2X) or Proximity Services synchronization (ProSe) services. For example, by using joint GNSS timing references and LTE cellular network timing references for V2X or ProSe system synchronization benefits of using GNSS technologies to improve synchronization procedure for LTE based V2X or ProSe services can be enabled, including: (1) accurate and stable timing, (2) availability of a global and stable timing reference and (3) ability to propagate GNSS timing by user equipment having sufficient GNSS signal quality.
