Abstract

A device capability discovery method and a P2P device are provided, and relate to the communications field and the distributed hardware field, to shorten time consumed to obtain capability information of a discovered device. A P2P device receives a probe request frame from another device. The P2P device returns a probe response frame including capability information of the P2P device. A device that receives the probe response frame can obtain a capability of the device in a device discovery phase. Alternatively, a P2P device sends a probe request frame including capability information of the P2P device to another device, so that the another device can obtain a capability of the device in a device discovery phase.
