Abstract (en)
[origin: WO2020092831A1] A device of a New Radio (NR) User Equipment (UE), a method and a machine readable medium. The method includes: encoding for transmission a packet in a cellular vehicle to everything (V2X) network, the transmission including one of a unicast transmission to a single vehicular user equipment (V-UE), or a groupcast transmission to a plurality of V-UEs; decoding a Hybrid Automatic Repeat Request (HARQ)-based message from at least one of the UEs, the HARQ-based message based on a HARQ configuration for the UE and being in response to the packet; and in response to a determination, based on the HARQ-based message, that a HARQ retransmission of the packet is to be encoded, encoding for transmission the HARQ retransmission.
