Title:
DEVICE-TO-DEVICE COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/114043
Kind Code:
A1
Abstract:
Provided is a device-to-device communication method. A first terminal device can use a correlation between resources and a first reference signal to determine a first resource corresponding to a target first reference signal, and send, on the determined first resource, acknowledgment information of at least some first reference signals to a second terminal device. In this way, the second terminal device can use the first resource to determine a first beam, so that the second terminal device can communicate with the first device by using the determined first beam. Exemplarily, the present application can be applied to the Internet of Vehicles, such as V2X, LTE-V, V2V, etc.
