Embodiment Construction

[0060] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0061] Please refer to figure 1 , which shows a schematic diagram of an implementation environment involved in various embodiments of the present application. The implementation environment may be a 5G NR cell. Such as figure 1 As shown, a 5G NR cell usually includes multiple TRPs and multiple user equipments. Exemplarily, the TRP (such as a base station) is a data sending end, and the user equipment is a data receiving end. Each user equipment receives services provided by multiple TRPs. The TRP determines the scrambling code sequence according to the configuration parameters. Afterwards, the data to be transmitted is scrambled by using the scrambling code sequence to obtain scrambled data. The TRP then sends the scrambled...

Abstract

The application discloses a method and device for generating a scrambling code sequence, belonging to the technical field of communication. The method includes: determining a scrambling code sequence according to configuration parameters of a TRP at a transceiver point, different TRPs correspond to different configuration parameters, and using the scrambling code sequence to scramble or descramble data. The present application solves the problem in the related art that the user equipment cannot obtain the data sent by the TRP from the received data and the system performance is poor, and achieves the effect of improving the system performance for data transmission.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710404714.2 and the invention title "Scrambling Code Sequence Generation Method and Device" filed with the China Patent Office on June 1, 2017, the entire contents of which are incorporated by reference in this application . technical field [0002] The present application relates to the field of communication technologies, and in particular to a method and device for generating a scrambling code sequence. Background technique [0003] With the rapid development of communication technology, users can obtain valid data anytime and anywhere based on wireless communication systems. The sending end (such as a base station) often uses scrambling technology to scramble the data to be transmitted, and the receiving end (such as user equipment (User Equipment, UE)) descrambles the scrambled data when receiving the scrambled data, get the raw data. The scrambling technology ...
