Embodiment Construction

[0042] As mentioned in the background technology, the number of retransmission times in the prior art is often indicated by a special signal, such as in LTE, indicated in the PDCCH; this indication method needs to occupy fixed physical resources, reducing the signal transmission efficiency.

[0043] In order to solve the above technical problems, an embodiment of the present application provides a communication synchronization method, the method includes: sending a synchronization preamble, the synchronization preamble includes indication information of the number of signal frame retransmissions, wherein the synchronization preamble is used to use The communication parties implement time and frequency domain synchronization; and send the signal frame corresponding to the synchronization preamble.

[0044] Compared with the prior art, the communication synchronization method provided by the technical solution of this application can indicate the number of retransmissions of the...

Abstract

A communication synchronization method and device, computer equipment and a storage medium, the communication synchronization method comprising: sending a synchronization preamble, with the synchronization preamble comprising indication information of the number of signal frame retransmissions, the synchronization preamble being used for enabling both communication parties to realize time and frequency domain synchronization; and sending a signal frame corresponding to the synchronization preamble. The scheme provided by the invention does not need to additionally occupy the retransmission times of the resource indication signal frame, and can improve the transmission efficiency of the signal.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication synchronization method and device, computer equipment, and a storage medium. Background technique [0002] In the existing communication system, the number of retransmissions of the signal is usually indicated by a special signal. In the Long Term Evolution (LTE for short) system, the number of retransmissions of the signal is indicated on the Physical Downlink Control Channel (Physical Downlink Control Channel). , PDCCH for short) needs to occupy fixed physical resources, and this method occupies a dedicated bit in the channel to indicate the number of retransmissions. [0003] However, in the existing communication system, fixed physical resources are used to indicate the retransmission times of the signal, which reduces the transmission efficiency of the signal. Contents of the invention [0004] The technical problem solved by this appli...
