Signaling Configuration Method, Device-to-device Discovery Method and Apparatus and Communication System

摘要

A signaling configuration method, device-to-device discovery method and apparatus and communication system. The method includes: configuring device-to-device discovery signals, the device-to-device discovery signals including a first discovery signal and a second discovery signal; wherein the first discovery signal is used for device-to-device initial discovery, detection or synchronization, and the second discovery signal is used for carrying auxiliary information. Mutual peer-to-peer (device-to-device) discovery or inter-small cell discovery may be achieved by the configured first discovery signal and second discovery signal, thereby alleviating mutual device-to-device interference, avoiding multiple times of transmission of signals, and lowering power consumption.
