Problems solved by technology
Each UE can obtain synchronization timing separately from different synchronization sources (for example, base station, core network, or satellite), and if these different synchronization sources are not synchronized with each other, multiple UEs may co-exist in the group Synchronize timing, resulting in data transmission failure during SL communication due to frame misalignment between UEs

A method and apparatus for synchronization in side link communications are disclosed. In one embodiment, a method for performing side link communications, the method comprising: determining, by a first wireless communication node, whether a second synchronization timing with at least one second wireless communication node is to be established, wherein the first wireless communication node and theat least one second wireless communication node form a side link communication group; in response to determining that the second synchronization timing is to be established, transmitting a first message based on a first synchronization timing to the at least one second wireless communication node, wherein the first message indicates a synchronization message which is configured to provide the second synchronization timing to the at least one second wireless communication node; and transmitting the synchronization message using a predefined side link synchronization resource to the at least onesecond wireless communication node.
Description
technical field [0001] The present disclosure relates generally to wireless communications and, more particularly, to methods and devices for synchronization in sidelink communications. Background technique [0002] Sidelink (Sidelink, SL) communication is wireless communication performed directly between two or more user equipments (hereinafter referred to as "UE"). In this type of communication, two or more UEs geographically close to each other can directly communicate without going through an eNode or a base station (hereinafter referred to as 'BS'), or without going through a core network. Data transmission in sidelink communications thus differs from typical cellular network communications, which transmit data to the BS (ie, uplink transmissions) or receive data from the BS (ie, downlink transmissions). In sidelink communication, data is transmitted directly from a source UE to a target UE over a unified air interface (eg, PC5 interface) without going through a BS. ...
