TIMING ADVANCE SLEW RATE CONTROL IN A NON-TERRESTRIAL NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 17655883 titled 'TIMING ADVANCE SLEW RATE CONTROL IN A NON-TERRESTRIAL NETWORK

Simplified Explanation

The abstract of this patent application describes a wireless communication system where a user equipment (UE) determines a differential UE-specific timing advance (TA) based on the difference between the timing advances associated with the current and previous global navigation satellite system (GNSS) position fixes. The UE then transmits an uplink message to a non-terrestrial network (NTN) node at a time determined by this differential timing advance.

• The user equipment (UE) calculates a differential timing advance based on the difference between the timing advances associated with the current and previous GNSS position fixes.
• The UE uses this differential timing advance to determine the timing for transmitting an uplink message to a non-terrestrial network (NTN) node.
• This technology allows for more accurate timing synchronization between the UE and the NTN node, improving the overall wireless communication performance.

Potential Applications

This technology can be applied in various wireless communication systems, including but not limited to:

• Cellular networks
• Satellite communication systems
• Internet of Things (IoT) networks

Problems Solved

This technology addresses the following problems in wireless communication:

• Timing synchronization between user equipment and non-terrestrial network nodes can be challenging, leading to reduced communication performance.
• Inaccurate timing synchronization can result in data transmission errors and increased latency.
• Previous methods of timing synchronization may not account for changes in the user equipment's position over time.

Benefits

The use of differential UE-specific timing advance based on GNSS position fixes offers several benefits:

• Improved timing synchronization between user equipment and non-terrestrial network nodes.
• More accurate and reliable data transmission.
• Reduced latency and improved overall communication performance.

Original Abstract Submitted

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a differential UE-specific timing advance (TA) based at least in part on a difference between a first UE-specific TA associated with a current global navigation satellite system (GNSS) position fix and a second UE-specific TA associated with a previous GNSS position fix. The UE may transmit, to a non-terrestrial network (NTN) node, an uplink message at a time that is based at least in part on the differential UE-specific TA. Numerous other aspects are described.
