Abstract: Example signal receiving methods and apparatus are described. One example method includes receiving a time-domain signal sent by a sending device. The time-domain signal is replicated to obtain N time-domain signals. N window functions are configured, where the N window functions are in a one-to-one correspondence with the N time-domain signals. An operation is performed on each of the N time-domain signals based on a corresponding window function to obtain N windowed time-domain signals. The N windowed time-domain signals are separately converted to obtain N frequency-domain signals. An RB corresponding to an interference frequency is determined. One or more RBs are selected from each of the N frequency-domain signals and are arranged in sequence based on indexes to obtain a target frequency-domain signal.

Abstract: A method for displaying a graphical user interface (GUI) based on a gesture is implemented by an electronic device. The method includes displaying a first GUI on a touchscreen of the electronic device, where the first GUI includes two or more entries, and the entry includes at least two interface elements. The method further includes receiving a first gesture of a user on the touchscreen. The method further includes displaying a second GUI on the touchscreen in response to the first gesture, where the second GUI includes two or more entries, and the entry includes at least one interface element. A quantity of entries in the second GUI is greater than a quantity of entries in the first GUI, and a quantity of interface elements in the second GUI is less than a quantity of interface elements in the first GUI.

Abstract: Embodiments of the present invention disclose an optical transmitter and an optical transmission method. An embodiment of the present invention includes a directly modulated laser array and a micro-ring group array, where the directly modulated laser array may output multiple channels of optical signals, each directly modulated laser is correspondingly provided with one circular waveguide group and one first waveguide, each circular waveguide group may couple a part of optical signals output by a directly modulated laser corresponding to the circular waveguide group to a same second waveguide, and the second waveguide aggregates optical signals from circular waveguide groups and outputs an aggregated optical signals. The micro-ring group array implements not only filtering but also multiplexing, which effectively reduces a quantity of elements, reduces a size of an optical transmitter, and reduces costs.

Abstract: This application provides a message processing method and system, and a user plane function UPF device. The method includes: receiving user equipment (UE) authentication information sent by a session management function (SMF) device; matching a received uplink message of the UE with the UE authentication information, and if the matching succeeds, sending the uplink message that includes the UE authentication information to a first application (APP); and performing authentication by the first APP on the UE according to the UE authentication information. In the foregoing process, authentication on the UE does not need to be performed by a remote APP. This simplifies the authentication process, reduces network resource overhead, speeds up authentication on UEs, reduces the latency of UE authentication, and further increases the application switching speed.

Abstract: A communication control method and apparatus, a terminal, and a network platform, where after generating a virtual subscriber identity module (SIM) card application request, the terminal sends the virtual SIM card application request to the network platform, then receives target virtual SIM card data returned by the network platform, and configures a target virtual SIM card in a baseband chip such that a user can conveniently change a SIM card only by downloading virtual SIM card data from the network platform using a network, regardless of a location of the user and time. In addition, according to the method, the user can conveniently select, with reference to displayed information about baseband chips, a baseband chip in which the target virtual SIM card data is configured, and does not need to repeatedly detach and mount a SIM card slot of the terminal for confirmation.
