Abstract: A terminal device obtains coding information that includes a first information bit and a second information bit. The terminal device selects, based on the first information bit, K groups from a codebook having L groups as activation groups, where both L and K are positive integers, and K is less than L. The terminal device then selects, based on the second information bit, a sequence from each of the activation groups as an activation sequence, and obtains a first sequence by superimposing the K activation sequences.

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: A mobile terminal includes a display screen, an earpiece assembly, and a camera. The earpiece assembly includes an earpiece and a sound conduction tube in communication with the earpiece. They form a stepped structure, and a surface that is used to connect to the sound conduction tube is a first stepped surface. The camera includes a body and a lens connected to the body; the body and the lens form a stepped structure, and a surface that is on the body and that is used to connect to the lens is a second stepped surface. The display screen is provided with a notch, and the sound conduction tube and the lens are located in the notch. In a direction perpendicular to the display screen, the display screen covers a part of the first stepped surface and/or a part of the second stepped surface.
