Abstract: Embodiments of the present disclosure disclose a data transmission method and a communications device. The method in the embodiments of the present disclosure includes: obtaining, by a first communications device, a transmission mode instruction, where the transmission mode instruction is used to instruct to use a frequency-domain repetition mode to transmit data, and the frequency-domain repetition mode means that same data is repeatedly transmitted on different frequency-domain resources; determining, by the first communications device, the frequency-domain repetition mode based on the transmission mode instruction; and performing, by the first communications device, data transmission with a second communications device in the frequency-domain repetition mode.

Abstract: Communication method and apparatus provide a network device sends a first signal to a first terminal device on a first resource element; the network device receives a fourth signal on a second resource element, where the second resource element and the first resource element at least partially overlap or are adjacent to each other; and the network device sends downlink data by using a first beamforming BF weight, where the first BF weight is obtained based on signal processing performed on the fourth signal, and an operation amount of the signal processing is less than an operation amount of matrix inversion or matrix decomposition. An air interface is used as a calculation resource to reduce calculation complexity of a baseband.

Abstract: This application discloses a precoding method and apparatus, and an information transmission method and apparatus, and relates to the field of communications technologies, to help improve overall performance of a plurality of data streams corresponding to a same codeword. The precoding method includes: decomposing a channel matrix into a product of a matrix Q, a matrix R, and a matrix PH, where the matrix PH is a conjugate transpose matrix of a matrix P, both the matrix Q and the matrix P are unitary matrices, and the matrix R is an upper triangular matrix; and precoding to-be-sent data based on the matrix P.

Abstract: A first device obtains first detection data of network performance between a steering function SF device and a first user plane UP device, where the first UP device is a UP device in a communication system in which a control plane CP is separated from a UP. Then, the first device configures the SF device and the first UP device based on the first detection data, to enable a first user to access a network through the SF device and the first UP device, where the first detection data meets a network performance requirement of the first user.
