RANDOM ACCESS PROCEDURES FOR SATELLITE COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240324029 titled 'RANDOM ACCESS PROCEDURES FOR SATELLITE COMMUNICATIONS

Simplified Explanation: The patent application describes systems and methods for random access in a wireless communication system, particularly in a satellite-based radio access network. The method involves estimating timing advance, transmitting a random access preamble, and enabling random access in the presence of long propagation delays.

  • Utilizes open-loop timing advance estimation for random access in a wireless communication system.
  • Enables random access in a satellite-based radio access network.
  • Improves efficiency and reliability of random access procedures in wireless communication.
  • Facilitates communication between wireless devices and base stations.
  • Addresses challenges posed by long propagation delays in satellite-based networks.

Potential Applications: This technology can be applied in satellite-based communication systems, IoT devices, mobile networks, and other wireless communication environments where random access is required.

Problems Solved: 1. Overcoming long propagation delays in satellite-based radio access networks. 2. Enhancing the efficiency of random access procedures in wireless communication systems. 3. Improving the reliability of communication between wireless devices and base stations.

Benefits: 1. Increased reliability and efficiency of random access procedures. 2. Enhanced communication capabilities in satellite-based networks. 3. Improved overall performance of wireless communication systems.

Commercial Applications: The technology can be utilized in satellite communication services, IoT networks, mobile telecommunications, and other industries requiring efficient random access procedures in wireless communication systems.

Questions about Random Access in Wireless Communication Systems: 1. How does the open-loop timing advance estimation procedure improve random access in wireless communication systems? 2. What are the specific challenges associated with random access in satellite-based radio access networks?


Original Abstract Submitted

systems and methods are disclosed for random access in a wireless communication system such as, e.g., a wireless communication system having a non-terrestrial (e.g., satellite-based) radio access network. embodiments of a method performed by a wireless device and corresponding embodiments of a wireless device are disclosed. in some embodiments, a method performed by a wireless device for random access comprises performing an open-loop timing advance estimation procedure to thereby determine an open-loop timing advance estimate for an uplink between the wireless device and a base station. the method further comprises transmitting a random access preamble using the open-loop timing advance estimate. in this manner, random access can be performed even in the presence of a long propagation delay such as that present in a satellite-based radio access network. embodiments of a method performed by a base station and corresponding embodiments of a base station are also disclosed.
