METHOD FOR SENDING AND DETECTING SYNCHRONISATION INFORMATION, AND USER DEVICE

摘要

Disclosed in the present application are a method for sending and detecting synchronisation information, and a user device. The method comprises: a sending device sends a synchronisation signal, and on the basis of its own network connection state and/or reference synchronisation source information, determines whether to send synchronisation information on a synchronisation channel corresponding to the synchronisation signal; if determining to send synchronisation information on the synchronisation channel, then the sending device, on the basis of its own network connection state and/or reference synchronisation source information, determines the synchronisation information that needs to be sent on the synchronisation channel and, on appointed physical resources, sends the determined synchronisation information by means of the synchronisation channel. The present application provides a solution for sending synchronisation information in a D2D application scenario; the sending device can, on the basis of its own network connection state and/or reference synchronisation source information, determine whether to send synchronisation information on a synchronisation channel corresponding to a synchronisation signal, and the synchronisation information carried in a synchronisation channel can transfer between user devices the synchronisation information thereof, expanding the scope of synchronisation.
