Abstract: This application provides example scrambling-based data transmission methods and apparatuses. A scrambling manner is determined based on a sending waveform. The scrambling manner can include frequency domain scrambling, time domain scrambling, or time-frequency domain scrambling. To-be-scrambled data can be scrambled based on the scrambling manner, to obtain scrambled output data. The scrambled output data can be sent. The sending waveform can be a discrete Fourier transform spreading orthogonal frequency division multiplexing (DFT-s-OFDM) waveform or a cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) waveform.

Abstract: Example data transmission methods and apparatus are described. One example method includes obtaining at least two signature sequences used to perform multiple access for at least two to-be-sent data packets by a user equipment. The user equipment processes the at least two data packets by respectively using corresponding signature sequences, to obtain at least two transmit sequences. The user equipment sends the at least two transmit sequences to a network device on a same time-frequency resource. Then the network device obtains the at least two signature sequences used by the user equipment to send the at least two transmit sequences, and separately detects a corresponding transmit sequence based on each signature sequence, to obtain the at least two data packets. The user equipment can transmit a plurality of data packets on a same time-frequency resource in a same slot.
