Abstract: Uplink (UL) feedback-based hybrid automatic repeat request (HARQ) retransmission may be proposed as an example for improving downlink (DL) broadcast for vehicle-to-everything (V2X) communication, especially for V2V (vehicle-to-vehicle) communication. An eNodeB (eNB) receives, from a neighboring eNB, an HARQ feedback transmitted by a user equipment (UE), and determines whether an HARQ is to be re-transmitted on the basis of the received HARQ feedback.

Abstract: A user equipment (UE) measures a sidelink (SL) resource occupancy level, and reports the measured SL resource occupancy level to an eNodeB (eNB). The measured SL resource occupancy level may be reported to the eNB when a predetermined event occurs. For example, the predetermined event may be a case in which the measured SL resource occupancy level is greater than or less than a threshold value. The SL resource occupancy level may be referred to as a channel busy ratio (CBR).
