Title:
METHOD AND DEVICE FOR TRANSMITTING REFERENCE SIGNAL IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/101308
Kind Code:
A1
Abstract:
A method by which a first device performs wireless communication, and a device for supporting same are provided. The method comprises the steps of: receiving information associated with a first symbol for transmitting a channel state information-reference signal (CSI-RS); determining whether the CSI-RS is transmitted on the first symbol on the basis of the information associated with the first symbol and information associated with a second symbol for transmitting a physical sidelink shared channel (PSSCH); transmitting first sidelink control information (SCI) to a second device on the basis of a resource associated with a physical sidelink control channel (PSCCH); and transmitting, to the second device, second SCI including information associated with a channel state information (CSI) request on the basis of the resource associated with the PSSCH.
