Abstract
Provided in embodiments of the present invention are a data scrambling method and device. The data scrambling method includes: a first device determining pieces of scrambling information corresponding to multiple physical channels, wherein different physical channels correspond to different pieces of scrambling information; and the first device performing descrambling of a received physical channel and/or scrambling of a physical channel to be transmitted based on the scrambling information.
