TIMING SYNCHRONIZATION FOR NON-TERRESTRIAL NETWORK COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17884458 titled 'TIMING SYNCHRONIZATION FOR NON-TERRESTRIAL NETWORK COMMUNICATIONS

Simplified Explanation

• • Patent Abstract:**

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message from a first non-terrestrial network cell indicating cell synchronization information for a second non-terrestrial network cell. The cell synchronization information may indicate synchronization status and timing offset values between the two cells. The UE uses this information to calculate timing for signaling and receive signals from the second cell.

• • Potential Applications:**

- Satellite communication systems - Mobile networks in remote areas - Internet of Things (IoT) devices in non-terrestrial environments

• • Problems Solved:**

- Ensuring proper synchronization between non-terrestrial network cells - Efficient communication in challenging environments - Seamless handover between different network cells

• • Benefits:**

- Improved reliability of wireless communication - Enhanced coverage in remote or non-terrestrial areas - Optimal performance of IoT devices in diverse environments

Original Abstract Submitted

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message from a first non-terrestrial network cell indicating cell synchronization information for a second non-terrestrial network cell. In some examples, the cell synchronization information may indicate whether the first non-terrestrial network cell and the second non-terrestrial network cell are synchronized at a reference point. Additionally, or alternatively, the cell synchronization information may indicate a timing offset value between a first uplink time synchronization reference point of the first non-terrestrial network cell and a second uplink time synchronization reference point of the second non-terrestrial network cell. The UE may calculate a timing associated with signaling from the second non-terrestrial network cell based at least in part on the cell synchronization information. The UE may receive one or more signals from the second non-terrestrial network cell based at least in part on the calculated timing.
