Abstract: A D2D link discovery method, which includes: obtaining, by UE, a neighboring UE list from a server, where the neighboring UE list includes related information of M neighboring UEs, and the related information is information required by the UE to determine whether a D2D connection to corresponding neighboring UE can be established by using a multiple-antenna technology; extracting, by the UE, the related information of the M neighboring UEs from the neighboring UE list, and determining N neighboring UEs from the M neighboring UEs based on the related information of the M neighboring UEs, where the N neighboring UEs are UEs to which D2D connections can be established by the UE by using the multiple-antenna technology; and performing, by the UE based on the multiple-antenna technology, link mapping between the UE and the N neighboring UEs to obtain respective links corresponding to the N neighboring UEs.
