    for each respective AV of the fleet of AVs, select one of a plurality of communication channels as a designated communication channel to transmit and receive transmission acknowledgments (ACKs) based on the designated communication channel having a highest transmission reliability of the plurality of communication channels;

    transmit data packets to the fleet of AVs using one or more of the plurality of communication channels other than the designated communication channel;

    in response to transmitting each respective data packet to the respective AV, initiate a timer for a predetermined period for receiving a corresponding ACK from the respective AV over the designated communication channel;

    based on transmitting the data packets to the fleet of AVs, receive ACKs from each respective AV of the fleet of AVs over the designated communication channel;

    receive data packets from the fleet of AVs over communication channels other than the designated communication channel; and
