Abstract
Provided is a timing synchronization method, comprising: setting a transmission period and a delay time of a signal to be transmitted by a transmitter; generating, by the transmitter, a beacon signal in a data format including the transmission period and the delay time; transmitting, by the transmitter, the beacon signal with an event time obtained by adding the delay time to the transmission period; and receiving the beacon signal and determining, by a receiver, a reception timing based on the event time.
Claims20
A timing synchronization method, comprising:
- setting a transmission period and a delay time of a beacon signal to be transmitted by a transmitter;
- generating and transmitting, by the transmitter, a beacon signal in a data format including the transmission period and the delay time;
- receiving, by a receiver, the beacon signal;
- determining, by the receiver, a reception timing of a next beacon signal to be transmitted by the transmitter based on an event time obtained by adding the delay time to the transmission period;
- and
- generating and transmitting, by the transmitter, the next beacon signal at the event time.
A transmission and reception system comprising a transmitter and a receiver, wherein
- the transmitter comprises
- a setting unit for setting a transmission period and a delay time of a beacon signal to be transmitted;
- a data generation unit for generating a beacon signal in a data format including the transmission period and the delay time stored in a payload;
- and
- a transmitting unit for transmitting the beacon signal at an event time obtained by adding the delay time to the transmission period set by the setting unit when the transmitter transmitted the previous time;
- the receiver comprises
- a receiving unit for receiving the beacon signal;
- and
- a timing determination unit for determining a reception timing based on the event time.
A non-transitory computer readable storage medium having recorded thereon a program that causes the computer to perform a timing synchronization method, comprising:
- setting a transmission period and a delay time of a beacon signal to be transmitted by a transmitter;
- generating and transmitting, by the transmitter, a beacon signal in a data format including the transmission period and the delay time;
- receiving, by a receiver, the beacon signal;
- determining, by the receiver, a reception timing of a next beacon signal to be transmitted by the transmitter based on an event time obtained by adding the delay time to the transmission period;
- and
- generating and transmitting, by the transmitter, the next beacon signal at the event time.
