Abstract
The present disclosure provides a communication method of an electronic shelf label system, a system, and a computer device. The method includes: repeatedly sending, by each of the plurality of base stations, a synchronization frame, wherein the synchronization frame includes a packet sequence number, and each of the synchronization frames includes a different packet sequence number; receiving, by the electronic shelf label, the synchronization frame at a receiving time point scheduled to wake up; determining whether the packet sequence number of the synchronization frame is the same as a packet sequence number corresponding to the receiving time point; and adjusting, if both are the same, by the electronic shelf label, a duration of the next sleep to compensate for the time difference, so as the next reception of a synchronization frame includes a packet sequence number corresponding to the receiving time point.
