Abstract: The present disclosure relates to Wi-Fi link sleep and wake-up methods, electronic devices, and systems. In one example method, a first electronic device establishes a Wi-Fi direct link with a second electronic device. The first electronic device is a group owner (GO) of Wi-Fi Direct. The second electronic device is a group client (GC) of Wi-Fi Direct. The second electronic device may send a first request message to the first electronic device to trigger the first electronic device to enable Wi-Fi link sleep. When a wireless projection service is suspended, a Wi-Fi link used for wireless projection enters a low-power state in a timely manner. When the Wi-Fi direct link sleeps, the second electronic device may send a wake-up request message to the first electronic device to trigger the first electronic device to wake up the Wi-Fi link.

Abstract: A device control system is disclosed. The system includes a first mobile terminal and a second mobile terminal. After enabling a wireless hotspot function, the first mobile terminal establishes a wireless fidelity (Wi-Fi) connection to the second mobile terminal, and transmits data to the second mobile terminal in a MIMO Wi-Fi antenna working mode. The first mobile terminal may monitor a remaining battery level and/or a device temperature of the mobile terminal. When the remaining battery level is less than a first battery level threshold and/or the device temperature is greater than a first temperature threshold, the first mobile terminal switches the Wi-Fi antenna working mode as SISO, limits a maximum forwarding rate of a TCP packet or a UDP packet to a first rate, and/or no longer responds to a probe request. In this way, power consumption of the first mobile terminal is reduced.

Abstract: The present invention discloses a protection circuit of Power Over Ethernet (POE) port and an Ethernet power-sourcing equipment. The port protection circuit includes: a first common mode suppression component, a second common mode suppression component, and a rectifier bridge. A first input end and a second input end of the rectifier bridge are connected to a first direct current output end and a second direct current output end of a PoE control chip, respectively. A first output end or a second output end of the rectifier bridge is connected to an uncharged signal line of a PoE port. An end of the first common mode suppression component is connected to the first output end of the rectifier bridge, and another end thereof is grounded. An end of the second common mode suppression component is connected to the second output end of the rectifier bridge, and another end thereof is grounded.

Abstract: A data processing method, a related device, and a system are provided. The method executed by a first network device includes receiving PDH frame data; loading the PDH frame data and a stuffing bit into a virtual container to obtain the virtual container that includes the PDH frame data, where the stuffing bit in the virtual container carries information about a clock frequency difference between a clock frequency of the Ethernet and a clock frequency of the PDH frame data; and performing virtual-container PWE3 encapsulation on the virtual container to obtain a virtual-container PWE3 packet. In at least some embodiments, difficulty in recovering the clock frequency of the PDH frame data when the PDH frame data is transmitted in the Ethernet is reduced, clock frequency jitters and drifts caused by the clock frequency recovery are reduced, and user experience is improved.

Abstract: The present disclosure relates to terminal devices, multi-link communication methods, and chips. In one example method, when a terminal device supports Wi-Fi and D2D (for example, V2X) communication, the terminal device may communicate with another terminal device in a multi-link collaborative transmission manner such as a Wi-Fi link and a D2D link to implement multi-link accelerated transmission in a local area network.
