Title:
METHOD FOR TRANSMITTING DMRS PATTERN INDICATION INFORMATION, AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/056579
Kind Code:
A1
Abstract:
Provided are a method for transmitting DMRS pattern indication information, and a communication apparatus, wherein same are applicable to scenarios, such as V2X, an Internet of Vehicles, connected vehicles, intelligent connected vehicles, and automatic driving. The problem of the waste of resources of sidelink control information that is brought about by the repeat indication of a DMRS pattern can be solved thereby. The method comprises: a first terminal device determining, according to the number of DMRS patterns of a physical sidelink shared channel (PSSCH) in resource pool configuration information, whether sidelink control information (SCI) comprises DMRS pattern indication information; and the first terminal device sending the SCI to a second terminal device. By means of the embodiments of the present application, the waste of resources of sidelink control information caused by the repeat indication of a DMRS pattern can be avoided, and the utilization rate of communication resources can be improved.
