METHOD AND APPARATUS FOR PERFORMING COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18151208 titled 'METHOD AND APPARATUS FOR PERFORMING COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The abstract describes methods and apparatuses for wireless communication in a wireless communication system. Here are the key points:
- A user equipment (UE) receives information related to a satellite's ephemeris (orbit) and its validity duration from a base station.
- The UE restarts a validity timer based on updated satellite ephemeris information received from the base station while the timer is running.
- The UE obtains timing advance (TA) measurements for the satellite based on the ephemeris information before the validity timer expires or stops.
- The UE obtains a second TA for the satellite based on the updated ephemeris information before the timer expires or stops again based on a second validity duration.
Potential applications of this technology:
- Wireless communication systems that rely on satellite connectivity, such as satellite-based internet services or satellite communication networks.
- Mobile devices or equipment that need to maintain accurate timing and synchronization with satellites, such as in navigation systems or location-based services.
Problems solved by this technology:
- Ensures that the UE has up-to-date satellite ephemeris information, which is crucial for accurate communication and positioning.
- Allows the UE to obtain timing advance measurements for satellites within the validity duration, improving the accuracy of wireless communication and location-based services.
Benefits of this technology:
- Improved accuracy and reliability of wireless communication in satellite-based systems.
- Enhanced performance of navigation systems and location-based services by maintaining accurate timing and synchronization with satellites.
- Efficient utilization of satellite resources by updating ephemeris information only when necessary.
Original Abstract Submitted
Methods and apparatuses for performing communication in a wireless communication system. A user equipment (UE) receives first satellite ephemeris information related to a first satellite and information related to a first validity duration corresponding to the first satellite from a base station; and restarts a first validity timer, based on second satellite ephemeris information related to the first satellite being received from the base station while the first validity timer having the first validity duration is running. The UE obtains a first TA for the first satellite based on the first satellite ephemeris information before the first validity timer restarts, expires, or stops after starting based on the first validity duration, and the UE obtains a second TA for the first satellite based on the second satellite ephemeris information before the first validity timer expires or stops after restarting based on a second validity duration.
