Abstract: This application discloses a scrambling code sequence generation method and apparatus, and belongs to the field of communication technologies. The method includes: determining a scrambling code sequence based on a configuration parameter of a transmission reception point TRP, where different TRPs correspond to different configuration parameters; and scrambling or descrambling data by using the scrambling code sequence. This application is used for data transmission, resolves a problem in a related technology that system performance is relatively poor because user equipment cannot better obtain, from received data, data sent by a TRP, and improves system performance.
