Abstract

The present disclosure provides a scrambling processing method, a descrambling processing method, and a device. The scrambling method includes: determining a first scrambling sequence and a second scrambling sequence respectively; scrambling control information included in a control channel by using the first scrambling sequence, and scrambling service data to be transmitted by a traffic channel by using the second scrambling sequence; and respectively sending the scrambled control information and the scrambled service data to a receiving end through direct links. The embodiment of the presentdisclosure achieves the purpose of scrambling the control information and the service data sent by the sending end in the direct links, and improving the transmission performance of the direct link.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, to a scrambling processing method, a descrambling processing method and a device. Background technique [0002] V2X (Vehicle to Everything, wireless communication technology for vehicles) is a new generation of information communication technology that connects vehicles to everything. Among them, V represents a vehicle, and X represents any object that interacts with the vehicle, mainly including vehicles, people, traffic roadside infrastructure and networks. C (Cellular)-V2X is a wireless communication technology for vehicles based on the evolution of cellular network communication technologies such as 4G and 5G. [0003] The standardization of C-V2X can be divided into three stages, LTE (Long Term Evolution, long-term evolution)-V2X, LTE-eV2X (enhanced technology research stage supporting V2X advanced business scenarios) and NR (New Radio, new air interface)- V2X.
