Abstract
A vehicle includes a processor configured to transmit a mmWave beacon signal during a probe phase of a first period; receive one or more mmWave beacon signals from one or more vehicles; generate a mmWave communication intention message for another period that is after the first period based on the received one or more mmWave beacon signals; and broadcast, during the first period, a packet including a mmWave transmission schedule for the another period generated based on the mmWave communication intention message.
Claims20
A vehicle comprising:
- a processor configured to:
- transmit a mmWave beacon signal during a probe phase of a first period;
- receive one or more mmWave beacon signals from one or more vehicles;
- generate a mmWave communication intention message for another period that is after the first period based on the received one or more mmWave beacon signals, the mmWave communication intention message indicating that the vehicle intends to communicate with one of the one or more vehicles over mmWave during the another period;
- and
- broadcast, during the first period, a packet including a mmWave transmission schedule for the another period generated based on the mmWave communication intention message.
A method for scheduling mmWave transmissions, the method comprising:
- transmitting, by a host vehicle, a mmWave beacon signal during a probe phase of a first period;
- receiving, by the host vehicle, one or more mmWave beacon signals from one or more vehicles;
- generating, by the host vehicle, a mmWave communication intention message for another period that is after the first period based on the received one or more mmWave beacon signals, the mmWave communication intention message indicating that the vehicle intends to communicate with one of the one or more vehicles over mmWave during the another period;
- and
- broadcasting, by the host vehicle, during the first period, a packet including a mmWave transmission schedule for the another period generated based on the mmWave communication intention message.
