Title:
METHOD AND DEVICE FOR PERFORMING SL COMMUNICATION ON BASIS OF ASSISTANCE INFORMATION IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2022/019540
Kind Code:
A1
Abstract:
A method by which a first device performs wireless communication, and a device for supporting same are provided. The method may comprise the steps of: receiving, from a second device, first sidelink control information (SCI) including scheduling information about a physical sidelink shared channel (PSSCH) through a physical sidelink control channel (PSCCH), the first SCI including information related to priority, information related to frequency resource allocation, information related to time resource allocation, information related to a demodulation reference signal (DMRS) pattern, and information related to a modulation and coding scheme (MCS); receiving, from the second device, assistance information including information related to one or more first resources and information related to a service type through the PSSCH; generating a medium access control protocol data unit (MAC PDU); selecting a sidelink (SL) resource from among the one or more first resources on the basis of the MAC PDU being related to the service type; and transmitting the MAC PDU on the basis of the SL resource.
