Abstract: This application provides a data transmission method and an apparatus, and may be applied to a wireless local area network system that supports 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and a next-generation protocol of 802.11be or Wi-Fi 8. According to the method, before a transmit device sends a to-be-sent data frame, the transmit device first sends a preemption frame, where the preemption frame includes first indication information used to determine first duration. After the transmit device sends the preemption frame, if a time period for which a channel keeps idle reaches a preset time period, the transmit device sends the to-be-sent data frame.

Abstract: In an embodiment a method includes performing, by a first terminal device, communication by using a first optimal receive beam of the first terminal device at a first location and an optimal transmit beam of a network device, when a signal quality of the first optimal receive beam and the optimal transmit beam does not meet a preset condition, determining, by the first terminal device, angle information obtained based on a reference direction and a first direction and outputting, by the first terminal device, orientation adjustment indication information based on the angle information or adjusting the first terminal device from the first location to a second location based on the angle information.

Abstract: A wireless signal quality evaluation method includes a second electronic device sending a signal evaluation request to a first electronic device. The method further includes receiving an evaluation result from the first electronic device according to a specified period. The evaluation result includes a quality parameter of a wireless signal received by the first electronic device at a collection time and information about the collection time, and the quality parameter of the wireless signal is obtained through calculation using at least two of the following parameters: a strength parameter, an interference parameter, a standard parameter, a quantity of access paths, and a CQI of the wireless signal. The method further includes displaying the quality parameter of the wireless signal received by the first electronic device at the collection time.

Abstract: After discovering an electronic device in a to-be-network-configured state, a wireless access device sends, at ultra-low power, a name of a wireless local area network in which the wireless access device is located to an electronic device, and/or sends, at ultra-low power, a message in response to a network configuration request to the electronic device. After the electronic device receives the name of the wireless local area network in which the wireless access device is located and the message in response to the network configuration request which are sent by the wireless access device, the electronic device negotiates with the wireless access device to transmit a password of the wireless local area network in which the wireless access device is located, and is connected to the wireless access device based on the name and the password of the wireless local area network in which the wireless access device is located.

Abstract: In an example implementation, a first electronic device connects to a non-authentication network of a wireless access device; a server randomly generates an authorization code, and the first electronic device and the wireless access device obtains the authorization code; and the wireless access device sends, to the first electronic device, network configuration information encrypted by using an authorization code-based key. The first electronic device receives and decrypts the network configuration information encrypted by using the authorization code-based key, to obtain network configuration information, and the first electronic device accesses the wireless access device based on the network configuration information.

Abstract: A communication method applied to a customer-premises equipment (CPE), where the CPE works in a bridging mode, and the method includes that the CPE sends a first dialing request to a mobile communications network. The CPE accesses the mobile communications network after receiving a first dialing response. The CPE bridges a first public Internet Protocol (IP) address in the first dialing response to a router connected to the CPE. The CPE sends a second dialing request to the mobile communications network after accessing the mobile communications network. The CPE receives a second dialing response, obtains a second public IP address from the second dialing response, and establishes a logical link to the mobile communications network to communicate with the mobile communications network without relying on the router connected to the CPE.
