A method of configuring a guard period, being applicable to a transmitter in Internet of Vehicles, and comprising: determining a target guard duration value corresponding to a guard period; and when data burst transmission is to be performed, sending target data of the data burst transmission to a receiver in the Internet of Vehicles starting from a first time point, wherein the first time point is a time point having an interval of the target guard duration value from a start time point, and the start time point is a time point at which the data burst transmission is determined to be performed; wherein determining the target guard duration value corresponding to the guard period comprises: determining (101-31) a target transmission distance value between the transmitter and the receiver; and obtaining (101-32) the target guard duration value corresponding to the guard period according to the target transmission distance value and a data transmission speed; wherein determining (101-31) the target transmission distance value between the transmitter and the receiver comprises: in response to that the target data is unicast data, determining (101-311) a target transmission loss for data transmission between the transmitter and the receiver; and determining (101-312) the target transmission distance value with respect to the target transmission loss according to a pre-determined correspondence between transmission loss and transmission distance value. determining a target guard duration value corresponding to a guard period; and when data burst transmission is to be performed, sending target data of the data burst transmission to a receiver in the Internet of Vehicles starting from a first time point, wherein the first time point is a time point having an interval of the target guard duration value from a start time point, and the start time point is a time point at which the data burst transmission is determined to be performed; wherein determining the target guard duration value corresponding to the guard period comprises: determining (101-31) a target transmission distance value between the transmitter and the receiver; and obtaining (101-32) the target guard duration value corresponding to the guard period according to the target transmission distance value and a data transmission speed; determining (101-31) a target transmission distance value between the transmitter and the receiver; and obtaining (101-32) the target guard duration value corresponding to the guard period according to the target transmission distance value and a data transmission speed; wherein determining (101-31) the target transmission distance value between the transmitter and the receiver comprises: in response to that the target data is unicast data, determining (101-311) a target transmission loss for data transmission between the transmitter and the receiver; and determining (101-312) the target transmission distance value with respect to the target transmission loss according to a pre-determined correspondence between transmission loss and transmission distance value. in response to that the target data is unicast data, determining (101-311) a target transmission loss for data transmission between the transmitter and the receiver; and determining (101-312) the target transmission distance value with respect to the target transmission loss according to a pre-determined correspondence between transmission loss and transmission distance value. <EOS>
