    Abstract: Embodiments of this application provide a data transmission method and apparatus. A method at a transmit end includes: obtaining a first sequence, where the first sequence includes a first sub-sequence and a second sub-sequence; mapping the first sub-sequence into K third sub-sequences based on a preset sequence group; performing differential coding and phase modulation on the second sub-sequence to obtain a fourth sequence whose length is K′; obtaining K fifth sub-sequences based on the K third sub-sequences and the K′ fourth sub-sequences; and outputting a second sequence including the K fifth sub-sequences. A method at a receive end includes: obtaining a second sequence including K fifth sub-sequences, and detecting the K fifth sub-sequences based on a preset sequence group to obtain a first sub-sequence; and performing differential demodulation based on the first sub-sequence to obtain a second sub-sequence, so that a first sequence is determined.

    Abstract: A first communication apparatus receives resource configuration information from a second communication apparatus, where the resource configuration information includes a first resource that is configured by the second communication apparatus for the first communication apparatus for data transmission. The first communication apparatus releases, based on a preset condition, a second resource to which a first synchronization signal block SSB is mapped, where the second resource is a dedicated resource of the first communication apparatus, and the first resource includes the second resource.

    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.

    Abstract: Embodiments disclose an uplink data transmission method and apparatus. The method includes: determining M transmission areas allocated to a terminal device, and generating first information used to indicate the M transmission areas, where M is a positive integer, and the transmission area represents an air interface time-frequency resource that includes a time range and a frequency range that are specified by a communications system. The method also includes determining, for each transmission area of the M transmission areas, second information used to indicate a transport block size. The method also includes sending an indication message to the terminal device, so that the terminal device transmits uplink data according to the indication message, where the indication message includes the first information and the second information.
