Title:
COMMUNICATION METHOD, APPARATUS, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/093836
Kind Code:
A1
Abstract:
The present application relates to the field of wireless communications, in particular to sidelink signal transmission in a wireless communication system, and provides a communication method, apparatus, and system, capable of solving the problem in the prior art that a sidelink channel state information reference signal (CSI-RS) cannot be efficiently applied to sidelink beam management, thereby improving the sidelink beam management efficiency. The method may comprise: sending first sidelink control information (SCI), the first SCI instructing to send M CSI-RSs, and M being a positive integer greater than or equal to 2; and sending the M CSI-RSs, wherein the M CSI-RSs belong to a same time unit, the M CSI-RSs comprise a first CSI-RS and a second CSI-RS, the first CSI-RS is sent by using a first beam, the second CSI-RS is sent by using a second beam, and spatial domain parameters corresponding to the first beam and the second beam are different.
