SIDELINK HARQ APPARATUS AND METHOD FOR HANDLING HYBRID ARQ RETRANSMISSION IN SIDELINK OPERATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present disclosure relates to a technology for a sensor network, a machine to machine (M2M), a machine type communication (MTC), and the Internet of Things (IoT). The present disclosure may be used for intelligent services (smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety related services, etc.) based on the above technology. According to an embodiment of the present disclosure, in a wireless communication system, a terminal processes sidelink MAC PDU transmission/retransmission based on HARQ feedback, blind-based sidelink MAC PDU transmission/retransmission, or MAC PDU transmission/retransmission based on the two modes A method comprising: determining HARQ transmission mode configuration information for a sidelink logical channel; determining whether retransmission is necessary according to HARQ transmission mode setting information; It provides a method comprising the step of performing retransmission according to HARQ transmission mode setting information.
