A communication method, device, and system are provided, and belong to the field of communication technologies. The method includes: When a link from a first device to a second device is in a service bitstream transmission state, the first device sends a first control bitstream that includes a first error correction encoding mode to the second device, and then the first device receives a service bitstream that is sent by the second device and that is encoded in the first error correction encoding mode. This application can resolve a problem that a service bitstream cannot be transmitted when a device enters a training state to set an encoding mode. This application is used to set an error correction encoding mode of a service bitstream when a link is in a service bitstream transmission state.

In some examples, a method of manufacturing a semiconductor device comprises forming a first source field plate structure, the first source field plate structure comprising a first source field plate and a first field dielectric surrounding the first source field plate, forming a second source field plate surrounding the first source field plate structure, wherein the second source field plate is separated from the first source field plate by a second field dielectric, wherein a length of the first source field plate is greater than a length of the second source field plate, forming a third field dielectric separating the second source field plate from implant zones, forming a gate structure comprising: a gate electrode surrounding the first source field plate structure, and a gate dielectric separating the gate electrode from the implant zones, and forming a contact structure to provide an electrical connection to the first source field plate structure.

This application provides a method and an apparatus for discovering an edge service. The method includes: A first network element receives first information, where the first information includes first service information. The first network element receives second information, where the second information includes first domain name information. When the first domain name information corresponds to the first service information, the first network element determines, for a first terminal device, an application server that is the same as that of a second terminal device or an application server in an edge network that is the same as that of a second terminal device. The first network element sends a first rule to indicate a second network element to send first application server address information to the first terminal device, or the first network element sends a third rule, where the third rule includes second option information, and the second option information is used by a DNS server to determine application server address information. The method provided in this application can be used to determine a same application server or an application server in a same edge network for terminal devices belonging to a same terminal group, and reduce an interaction delay between the terminal devices in the terminal group.

Embodiments of this application provide a data processing method and apparatus, to scramble, by using one interleaver or one LDPC tone mapper, a bit sequence of a bitstream of a user to whom a plurality of RUs are allocated, so that hardware costs are reduced. The method includes: allocating a coded bitstream of a first user to M RUs or a first RU including M RUs, where the M RUs or the first RU is an RU allocated to the first user, and M is a positive integer greater than 1; reordering all bits in the coded bitstream by using a first interleaver or a first tone mapper.

This application discloses a message processing method and a related apparatus. In the message processing method, a terminal device receives a first push message of a first application that is sent by a push server; the terminal device receives a second push message of a second application that is sent by the push server; the terminal device displays the first push message and the second push message on a first user interface; the terminal device receives a first input operation performed by a user on the second push message; and the terminal device displays a second user interface in response to the first input operation, where a display form and/or a display sequence of the second push message on the second user interface are/is different from a display form and/or a display sequence of the second push message on the first user interface. In this way, an operation of querying a push message can be simplified, and user experience can be effectively improved.

Embodiments of this application provide a method and an apparatus for transmitting a physical layer protocol data unit, to design a short training field sequence for a larger channel bandwidth. The short training field sequence designed in this application has a smaller peak-to-average power ratio PAPR and better performance. The method includes: generating a physical layer protocol data unit PPDU that complies with the 802.11be standard, where the PPDU includes a short training field, and a quantity of subcarriers of a frequency domain sequence of the short training field is greater than 2048; and sending the PPDU on a target channel, where a bandwidth of the target channel is greater than or equal to 160 MHz.

Embodiments of the present invention provide a preamble sequence transmission method, apparatus, and system, which relate to the communications field and can enhance signal strength of a preamble sequence received by a base station, so as to increase a matching probability of the base station and increase efficiency of gaining access to the base station by user equipment. The method includes: acquiring system information or a physical broadcast channel PBCH that is broadcast by a base station, where the system information or the PBCH includes a preset physical random access channel PRACH, the preset PRACH includes m preset radio frames, and m is a positive integer; determining that a quantity of repetition times of a preamble sequence, which is used for random access, at a preset resource location of the preset PRACH is n, where 1 ≤ n ≤ 10m; and sending, at n preset resource locations of the preset PRACH, the preamble sequence to the base station.

This application provides a data transmission method, apparatus, and a system. The data transmission method includes: A first controller receives a data obtaining request from a second controller, where the data obtaining request requests to obtain data of a first sensor, the first controller supports a data interface corresponding to the first sensor, and the second controller does not support the data interface corresponding to the first sensor; the first controller receives first data from the first sensor; and the first controller sends converted first data to the second controller according to a first communication protocol. In this way, a second electronic apparatus can obtain data from the first sensor from a first electronic apparatus. This helps avoid redundant sensor configuration.

This application provides an access network device selection method and an apparatus, to select a proper non-3GPP access network device for a terminal device, and relates to the field of wireless communication technologies. In the method, the terminal device may indicate, to a DNS through one or more of first indication information, second indication information, and at least one GIN, whether the terminal device needs to support external authentication. Therefore, when selecting the non-3GPP access network device for the terminal device, the DNS may consider one or more of the first indication information, the second indication information, and the at least one GIN, to select the proper non-3GPP access network device for the terminal device based on the indication of the terminal device. For example, when the terminal device supports external authentication or needs to support external authentication, the DNS may select, for the terminal device, a non-3GPP access network device capable of performing external authentication. In this way, the DNS can support the terminal device in accessing a non-public network through a non-3GPP access network.
