As shown in FIG. 4, a transmitter (Tx) UE 405 may communicate with a receiver (Rx) UE 410. The transmitter UE 405 and/or the receiver UE 410 may correspond to one or more UEs described elsewhere herein, such as UE 120, UE 305, and/or the like. In some aspects, a UE 405, 410 may be integrated into a vehicle, may be located in or on the vehicle, and/or the like. A vehicle may include an autonomous vehicle, a semi-autonomous vehicle, a non-autonomous vehicle, and/or the like. Additionally, or alternatively, one or more of the UEs 405, 410 may not be associated with a vehicle. For example, a UE 405, 410 may be associated with infrastructure (e.g., traffic infrastructure, such as a traffic signal, a lane signal, a sensor, a traffic controller system, and/or the like), a pedestrian (e.g., via a wearable device), and/or the like.

The transmitter UE 405 and the receiver UE 410 may communicate via one or more sidelink channels 310 (e.g., to exchange SCI 325 and corresponding TBs 330), as described above in connection with FIG. 3. As used herein, the term transmitter (Tx) UE 405 is used to describe a UE that schedules transmission of a particular D2D communication and/or transmits the particular D2D communication to a receiver UE 410. As used herein, the term receiver (Rx) UE 410 is used to describe a UE that receives the particular D2D communication from the transmitter UE 405. A single UE (e.g., UE 120) may be capable of operating as a transmitter UE 405 (e.g., that transmits D2D communications to other UEs) and a receiver UE 410 (e.g., that receives D2D communications from other UEs).
