  • Patent number: 10044589
    Abstract: A method for supporting vehicular communication in a cellular-based communication system includes connecting at least one base station and a plurality of vehicles equipped with mobile communication devices. A centralized control entity coordinates packet transmissions of the vehicles. Adjustment of a packet transmission rate is done recursively, where parameters of packet transmission characteristics are measured and the control entity determines, based on the parameters of packet transmission characteristics, an optimal packet transmission rate. The vehicles and/or the control entity transmit packets use the optimal packet transmission rate.
