    Abstract: A method for determining a precoding matrix indicator, user equipment, and a base station are disclosed in embodiments of the present invention. The method includes: receiving a first reference signal set sent by a base station, where the first reference signal set is associated with a user equipment-specific matrix or matrix set; selecting a precoding matrix based on the first reference signal set, where the precoding matrix is a function of the user equipment-specific matrix or matrix set; and sending a precoding matrix indicator to the base station, where the precoding matrix indicator corresponds to the selected precoding matrix. In the embodiments of the present invention, CSI feedback precision can be improved without excessively increasing feedback overhead, thereby improving system performance.

    Abstract: A data transmission method and a device are disclosed. The method includes: receiving, by a third-party node in a specified first spectrum, a request message sent by a network side device that belongs to an operator different from an operator of the third-party node, where the request message is used to request the third-party node to forward data that is transmitted between the network side device and a terminal served by the network side device; returning, by the third-party node, a response message to the network side device in the first spectrum after the third-party node determines to accept the request of the network side device; and forwarding, by the third-party node in a second spectrum, the data that is transmitted between the network side device and the terminal, where the second spectrum is a spectrum of the operator to which the network side device belongs.

    Abstract: Embodiments of this application disclose a video image processing method and apparatus. A specific solution is as follows: obtaining identity information and location information of each subject in an ith video image frame; determining M main subjects from the ith video image frame based on identity information of subjects in N video image frames before the ith video image frame, where the identity information of the subjects in the N video image frames includes identity information of the M main subjects; cropping the ith video image frame based on location information of the main subjects, where a cropped ith video image frame includes the M main subjects; and scaling down or scaling up the cropped ith video image frame, so that a display displays the cropped ith video image frame based on a preset display specification.
