Title:
SIDELINK COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/131212
Kind Code:
A1
Abstract:
The present application provides a sidelink (SL) communication method, applied to two terminal devices for SL communication. The method comprises: a first terminal device sends a first reference signal for channel measurement to a second terminal device, a first time unit being located before a second time unit and associated with a second time unit, and the second time unit being a time unit for SL transmission between the first terminal device and the second terminal device; and the first terminal device receives, in a third time unit, first feedback information sent by the second terminal device, the first feedback information being determined by the second terminal device according to the first reference signal, the first feedback information being used for determining a parameter for the SL transmission, and the third time unit being located behind the first time unit and before the second time unit. In this case, the second terminal device performs channel measurement in advance before data transmission, and reports feedback information to the first terminal device, such that link adaptation is more precise, and the transmission performance is improved.
