Provided in the embodiment of the present invention are a discovery signal transmission method, a user device, and a base station. The method comprises the following steps: a second user device detects a first paging message sent by a base station, said first paging message instructing the second user device to send a discovery signal on a second resource (S210); the second user device, on the basis of the detected first paging message, determines the second resource (S220); and the second user device sends a discovery signal on the second resource (S230). Application of the discovery signal transmission method set forth in the present embodiment of the invention causes the base station to trigger the user device to send a discovery signal on a temporarily allocated resource, thereby avoiding the user device periodically sending a discovery signal on a system reserved resource. Without influencing the efficiency of detecting a discovery signal, the energy consumption of the user device is effectively reduced, and the user experience is improved. |
