Wireless communication device for data retransmission management
The patent US12047176B2 describes a wireless communication device designed to enhance data transmission efficiency among multiple devices. The device features a reception controller that receives signals from a transmission source and extracts data from these signals. It includes a detector that identifies retransmission requests from other devices based on their positions, utilizing specific channels for communication. A determination unit assesses whether to relay the data to the requesting device by evaluating the distance to its identified position. If the conditions are met, the device transmits the acquired data to the requesting device.
Additionally, the patent outlines various configurations for the detection and transmission processes. The detector can operate using feedback channels organized by geographical zones or relative zones based on the data transmission source's position. The determination unit further refines its decision-making by calculating distance differences and comparing them to predetermined thresholds. The system also includes provisions for retransmission requests when data acquisition fails, ensuring robust communication between devices. Overall, the patent presents a structured approach to managing data requests and transmissions in a wireless communication environment, aiming to improve connectivity and data reliability.
