USER DEVICE AND SIGNAL RECEIVING METHOD

摘要

In the present invention, a user device that performs communication between user devices comprises the following: a synchronized signal detection unit that detects an inter user-device synchronization signal that is sent from a user device of another cell or another carrier; a control unit that sets a reception timing on the basis of the inter user-device synchronization signal; and a reception unit that receives scheduling information or a discovery signal sent from the user device of another cell or another carrier within a time window that has been set on the basis of the inter user-device synchronization signal.
