UPLINK TIMING AND FREQUENCY SYNCHRONIZATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18468668 titled 'UPLINK TIMING AND FREQUENCY SYNCHRONIZATION

Simplified Explanation

The patent application describes methods and apparatuses for uplink timing and frequency synchronization in a wireless communication system. It involves a method for operating a user equipment (UE) that receives information from a base station (BS) regarding satellite ephemeris information, a common timing advance (TA), and a compensated frequency offset (FO). The UE then transmits a physical random access channel (PRACH) based on the common TA and the compensated FO, and receives a random access response (RAR) indicating a UE-specific TA and FO. For transmission of an uplink (UL) channel, the UE adjusts the TA and pre-compensates the FO based on the UE-specific TA and FO, respectively.

  • The patent application focuses on uplink timing and frequency synchronization in a wireless communication system.
  • It proposes a method for a user equipment (UE) to receive information from a base station (BS) regarding satellite ephemeris information, common timing advance (TA), and compensated frequency offset (FO).
  • The UE then transmits a physical random access channel (PRACH) based on the common TA and compensated FO, and receives a random access response (RAR) indicating a UE-specific TA and FO.
  • The UE adjusts the TA and pre-compensates the FO based on the UE-specific TA and FO for transmission of an uplink (UL) channel.

Potential applications of this technology:

  • Wireless communication systems that require accurate uplink timing and frequency synchronization.
  • Satellite communication systems where satellite ephemeris information is crucial for synchronization.
  • Mobile networks that rely on random access channels for initial communication establishment.

Problems solved by this technology:

  • Ensures accurate uplink timing and frequency synchronization in wireless communication systems.
  • Enables efficient communication establishment by adjusting timing advance and compensating frequency offset based on UE-specific information.
  • Improves overall system performance and reliability by minimizing synchronization errors.

Benefits of this technology:

  • Enhanced communication reliability and quality by maintaining accurate uplink timing and frequency synchronization.
  • Improved network efficiency and capacity through optimized timing advance and frequency offset adjustments.
  • Simplified initial communication establishment process through the use of random access channels and UE-specific information.


Original Abstract Submitted

Methods and apparatuses for uplink timing and frequency synchronization in a wireless communication system. A method for operating a user equipment (UE) includes receiving, from a base station (BS), information indicating satellite ephemeris information of a communication satellite associated with the BS, a common timing advance (TA), and a compensated frequency offset (FO). The method further includes transmitting a physical random access channel (PRACH) based on the common TA and the compensated FO and receiving a random access response (RAR) indicating a UE-specific TA and FO. The method further includes, for transmission of an uplink (UL) channel, adjusting a TA and pre-compensating a FO based on the UE-specific TA and FO, respectively.
