摘要
Various examples and schemes pertaining to shared negative acknowledgement (NACK) for groupcast and multicast in New Radio (NR) vehicle-to-everything (V2X) communications are described. An apparatus as a source user equipment (UE) transmits data to two or more destination UEs of a plurality of destination UEs via groupcast or multicast with hybrid automatic repeat request (HARQ). The apparatus then receives a NACK on a single time-frequency resource from at least one of the two or more destination UEs. The single time-frequency resource is shared by the plurality of destination UEs to transmit the NACK to the source UE.
