RELAY SYSTEM SYNCHRONIZATION METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2019/213940

A1

Disclosed are a relay system synchronization method and apparatus, and a computer device and a storage medium. The method may comprise: a relay node determining a first slot boundary; the relay node sending downlink data to a child node by means of time alignment between a second slot boundary of the downlink data sent to the child node and the first slot boundary; in addition, the relay node determining a first timing advance at least according to the following information: a second timing advance for the relay node to send uplink data to a parent node and the transmission delay between the relay node and the child node; and the relay node sending the first timing advance to the child node, wherein the first timing advance is used for the child node to determine the sending time for sending the uplink data to the relay node. By applying the solution of the present invention, the system performance, etc. can be improved.
