Title:
METHOD AND DEVICE FOR PERFORMING PC5 RRC CONNECTION-BASED HARQ FEEDBACK IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2020/218903
Kind Code:
A1
Abstract:
An operating method of a first device (100) in a wireless communication system is proposed. The method may comprise the steps of: receiving a PSSCH from a second device (200); on the basis of whether or not PC5 RRC connection exists between the first device (100) and the second device (200), determining an option associated with HARQ feedback; and performing the HARQ feedback through a PSFCH associated with the PSSCH on the basis of the option associated with the HARQ feedback.
