Abstract

Disclosed are a D2D communication method and a user equipment, the D2D communication method comprises following steps: a first user equipment determines a value of a scrambling parameter, the scrambling parameter comprising at least one of the following parameters: a common scrambling parameter and a specific scrambling parameter; the first user equipment scrambles a bit to be sent according to the value of the scrambling parameter; and the first user equipment sends the scrambled bits to be sent. According to the D2D communication method and the user equipment disclosed by the invention, thescrambling and descrambling of the transmission information can be realized in the D2D communication process, the feasibility of a D2D communication scheme is improved, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, relate to a device-to-device communication method and user equipment. Background technique [0002] The device-to-device proximity service (English full name: Device to Device Proximity Service, English abbreviation: D2D ProSe) between user equipment (English full name: User Equipment, English abbreviation: UE) has become a long-term evolution (English full name: Long Term Evolution, English abbreviation: hot topic of LTE) system. At present, the device-to-device (English full name: Device to Device, English abbreviation: D2D) communication function has been applied to some existing cluster systems and some walki-talki devices. Due to the great success of the commercialization of the LTE system, providing D2D ProSe on the basis of the physical layer of the LTE system can not only enrich the service range of the LTE system, but also enable D2D communication t...
