Abstract: This application discloses a multi-device connection establishment method and a device. The method includes: A first device sends a first message, where the first message is used to discover another device; the first device receives one or more second messages from one or more devices, where the second message is a response message for the first message; the first device determines, based on the one or more second messages, to establish a connection to a second device in the one or more devices; and the first device negotiates, with the second device, link information used to establish direct communication between the first device and the second device, and establishes a direct communication connection to the second device based on the link information. After a communication connection is established between devices based on discovery, link information is negotiated, and direct communication is established based on the link information, to form a system. In this way, there is no need to allocate specific roles to the devices. Therefore, the roles of the devices in the established distributed system are equivalent, and a service is not limited to a role problem.

Abstract: This application provides a communication method, a terminal device, and a storage medium. The communication method includes: A first terminal device performs a Wi-Fi P2P service in response to a first operation of a user, where the first terminal device uses a first channel to perform the Wi-Fi P2P service, and a bandwidth of the first channel is a maximum bandwidth supported by the first terminal device, and is 80 MHz or 160 MHz. When detecting that a signal-to-noise ratio and/or a channel load of the first channel meet a first preset condition, the first terminal device switches from the first channel to a second channel to perform the Wi-Fi P2P service, where a bandwidth of the second channel is 20 MHz or 40 MHz.

Abstract: A clock synchronization method, a device, and a system are provided. The method includes: A first device receives first information sent by a second device, where the first information includes second clock domain identification information. The first device updates clock domain identification information of the first device to the second clock domain identification information and sends a first synchronization request to the second device when quality of a signal between the first device and a second master device meets a first condition. The first device receives a first synchronization indication from the second device, where the first synchronization indication includes the second clock domain identification information and a first moment at which the second device sends the first synchronization indication. The first device synchronizes a clock of the first device to a second clock based on the second clock domain identification information and the first moment.

Abstract: This application discloses a resource management method and a device. The method is applied to a domain including a primary device and a plurality of secondary devices, and a plurality of interconnected devices in the domain form a team. The method includes: The primary device receives channel score information from each secondary device, generates first RRM information based on the received channel score information and channel score information of the primary device, and sends the first RRM information to each secondary device. The first RRM information indicates a priority ranking of channels, and a higher priority of a channel indicates a lower degree of interference to the channel. The primary device may perform priority ranking on information based on channel interference information reported by each channel, and preferentially allocate, to each device, a channel with less interference based on the priority ranking of the channels. Therefore, collaborative scheduling and anti-interference across an entire network can be implemented, and an overall throughput of the network can be improved.
