Abstract

Provided in an embodiment of the present invention are an information transmission method and user equipment (UE), the method comprising: a first UE monitors on a broadcasting resource in an equipment discovery resource an equipment discovery signal transmitted by other UEs on the broadcasting resource; the first UE forwards on a rebroadcasting resource in the equipment discovery resource all or a part of the monitored equipment discovery signals. An embodiment of the present invention reduces resource waste, and solves the problem of equipment overload.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to an information transmission method and user equipment. Background technique [0002] With the continuous development of communication technologies, most current mobile devices use various wireless technologies, for example, Bluetooth, Wireless Fidelity (Wireless Fidelity, WIFI for short), and the like. Operators of these technologies realize that direct device-to-device (D2D) communication between mobile devices will become hot in the future, and 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] In the device discovery phase of D2D communication, each user equipment (User Equipment, referred to as "UE") can maintain a database, which contains a list of r...
