Abstract

Provided are a device discovery method and terminal, the method comprising: acquiring a corresponding relationship between a service type and a resource block; acquiring, according to the corresponding relationship between the service type and the resource block, a first resource block corresponding to a service type to which a required service belongs; and monitoring a device discovery signal broadcasted on the first resource block, the device discovery signal broadcasted on the first resource block being broadcasted on the first resource block by a terminal providing the service of said service type.

Description

technical field [0001] The present invention relates to communication technology, in particular to a device discovery method and a terminal. Background technique [0002] With the continuous development of communication technologies, most of the current mobile device terminals use various wireless technologies such as Bluetooth and WI-FI. The application of these technologies makes operators realize that direct device-to-device (Device-to-Device, D2D) communication between mobile devices will become hot in the future. One of the key technologies of D2D communication is device discovery. The so-called device discovery means that a device needs to discover other surrounding devices, and at the same time let the surrounding devices discover the existence status of the device. [0003] Qualcomm's D2D (or Flash LinQ) system is a communication system that combines synchronization technology and OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multi...
