RANDOM ACCESS PROCEDURES FOR SATELLITE COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18731973 titled 'RANDOM ACCESS PROCEDURES FOR SATELLITE COMMUNICATIONS
The abstract describes systems and methods for random access in a wireless communication system, particularly in a non-terrestrial (e.g., satellite-based) radio access network.
- Open-loop timing advance estimation procedure is used to determine an estimate for uplink timing advance between a wireless device and a base station.
- The wireless device transmits a random access preamble based on the open-loop timing advance estimate.
- This allows for random access even in the presence of long propagation delays typical in satellite-based networks.
Potential Applications: - Satellite-based communication systems - Mobile communication networks with long propagation delays
Problems Solved: - Facilitating random access in wireless communication systems with significant propagation delays - Improving efficiency and reliability of uplink transmissions in satellite-based 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.
