1. A method for scrambling data, comprising:
receiving, by a terminal device, third configuration information configured by radio resource control (RRC) from a network device,
wherein the third configuration information comprises a plurality of scrambling parameters corresponding to control resource set groups;
receiving, by the terminal device, a plurality of downlink control information (DCIs) for scheduling a plurality of physical downlink shared channels (PDSCHs),
wherein the plurality of DCIs are located in different search spaces, and each of the search spaces comprises information related to the control resource set groups, and the control resource set groups correspond to scrambling information of the plurality of PDSCHs;
determining, by the terminal device, multiple pieces of the scrambling information corresponding to different PDSCHs according to the multiple different search spaces of the received plurality of DCIs; and
performing, by the terminal device, descrambling a received PDSCH based on the scrambling parameter determined based on the scrambling information among the plurality of scrambling parameters.
