Title:
COMMUNICATION METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/212505
Kind Code:
A1
Abstract:
The present application relates to a communication method, device, and system, applicable to fields such as the Internet of Vehicles, intelligent driving, assisted driving, and intelligent connected vehicles. The method comprises: a first terminal device detecting sidelink control information from at least one second terminal device, and determining a first time-frequency resource; the first terminal device transmitting first information to a third terminal device, the first information being used to trigger determination of second information; the first terminal device receiving, from the third terminal device, the second information indicating a second time-frequency resource, the second time-frequency resource being used to determine a time-frequency resource for transmitting data to the third terminal device; and the first terminal device determining a third time-frequency resource according to the second time-frequency resource and the first time-frequency resource, and transmitting first data to the third terminal device via the third time-frequency resource. The first terminal device can select a data transmission resource by taking both a monitoring result of the first terminal device and a monitoring result of the third terminal device into consideration, thus improving the quality of signal reception.
