Application: Wireless communication method and wireless communication device (Patent ID: US20240090071A1)

The patent filed by Sony Group Corp. discloses a wireless communication method and device that involve an electronic device determining the state of a link with a counterpart communication device by measuring a link maintenance message without transmitting a feedback message. The method includes transmitting a link control message to multiple receiving UEs to indicate the omission of an ACK signal if a reliable relationship is verified, and receiving ACK or NACK signals from responding UEs.

The electronic device, acting as a transmission UE in sidelink communication, performs link quality measurements with receiving UEs, sets timers based on the quality measurements, and sends additional link maintenance messages when timers expire. The method also involves setting timers based on information about link quality and previous measurements. Overall, the invention aims to enhance wireless communication reliability by optimizing feedback mechanisms and link maintenance processes between electronic devices and multiple UEs in a network.
