Method and apparatus for transmitting sidelink HARQ feedback information

Abstract:

Provided is a method of a receiver UE for transmitting sidelink HARQ feedback information. The method includes receiving a sidelink data channel (a physical sidelink shared channel, "PSSCH") over unicast or groupcast, determining a HARQ feedback mode for transmitting HARQ feedback information in response to the reception of the PSSCH, and transmitting the HARQ feedback information according to a result obtained by decoding the PSSCH based on the determined HARQ feedback mode.
