TRIGGERING TIMING SYNCHRONIZATION IN NON-TERRESTRIAL NETWORKS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18353808 titled 'TRIGGERING TIMING SYNCHRONIZATION IN NON-TERRESTRIAL NETWORKS

Simplified Explanation

The abstract of this patent application describes methods and apparatuses for a timing advance report in a Non-Terrestrial Network (NTN). The method involves a User Equipment (UE) receiving first information from a Base Station (BS) that includes satellite assistance information for a target satellite. The UE also receives second information from the BS that includes timing information, which includes the start time and duration for a synchronization operation. The UE determines whether a RACH-less synchronization operation is configured and initiates the synchronization operation based on the satellite assistance information and timing information by performing a RA (Random Access) procedure if the RACH-less synchronization operation is not configured.

  • The patent application describes a method for a UE to perform a synchronization operation in an NTN.
  • The UE receives satellite assistance information and timing information from a BS.
  • The timing information includes the start time and duration for the synchronization operation.
  • The UE determines whether a RACH-less synchronization operation is configured.
  • If the RACH-less synchronization operation is not configured, the UE initiates the synchronization operation by performing a RA procedure.

Potential applications of this technology:

  • This technology can be applied in satellite communication systems where synchronization between the UE and the satellite is crucial.
  • It can be used in IoT (Internet of Things) applications that rely on satellite connectivity.
  • This technology can be beneficial in remote areas where terrestrial networks are not available or reliable.

Problems solved by this technology:

  • The technology solves the problem of synchronizing the timing between the UE and the target satellite in an NTN.
  • It addresses the issue of configuring and initiating a synchronization operation in a RACH-less scenario.

Benefits of this technology:

  • The technology ensures accurate timing synchronization between the UE and the target satellite, improving the overall performance of the communication system.
  • It allows for efficient and reliable communication in NTN environments.
  • This technology enables seamless connectivity in areas where terrestrial networks are limited or unavailable.


Original Abstract Submitted

Methods and apparatuses for a timing advance report an NTN is provided. The method of UE comprises: receiving, from a BS, first information including satellite assistance information for a target satellite; receiving, from the BS, second information including timing information, wherein the timing information includes at least one of a start time and a time duration for a synchronization operation; determining whether a RACH-less synchronization operation is configured; and initiating, based on the satellite assistance information and the timing information, the synchronization operation by performing a RA procedure upon a determination that the RACH-less synchronization operation is not configured.
