Application: Terminal device, base station device, and method (Patent ID: US20230361865A1)
The patent filed by Sony Group Corp. describes a mechanism to enhance wireless link quality for transmissions from a terminal device on the ground to a non-ground station device. The terminal device includes a control unit that acquires information about the type of base station device and adjusts the transmission timing of signals to the base station device based on this information. The mechanism involves receiving System Information Blocks (SIB) and Random Access Responses (RAR) from the base station device, determining if the SIB contains satellite station-related information, and calculating a timing advance value for controlling uplink transmission timing based on specific values.
The claims in the patent detail the specific functions and configurations of the terminal device and base station device involved in the wireless communication process. These include determining the presence of satellite station-related information in the SIB, calculating timing advance values based on different scenarios, and considering factors such as orbital parameters and velocity of the satellite station. The method outlined in the patent involves receiving SIB and RAR, analyzing the content for satellite station-related information, and adjusting timing advance values accordingly to optimize transmission timing. Overall, the patent aims to improve wireless link quality by implementing a mechanism that takes into account specific information about the base station and satellite station involved in the communication process.
