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 communication apparatus determines a serving cell that can perform information synchronization with a to-be-activated SCell, where the serving cell is an activated cell or a known cell. The communication apparatus determines a first SSB in SSBs sent by the to-be-activated SCell, where the first SSB corresponds to a second SSB sent by the serving cell. The communication apparatus activates the to-be-activated SCell based on the first SSB sent by the to-be-activated SCell and timing information and beam information of the second SSB.

Abstract: The present disclosure provides example channel parameter estimation methods and related apparatuses. In one example method, a cable modem (CM) obtains a second data frame through a downlink channel between the CM and a cable modem termination system (CMTS). The second data frame is generated after a first data frame sent by the CMTS is modulated through the downlink channel, a zero-bit-loaded symbol of the first data frame includes no valid codeword, but includes a zero-bit-loaded NCP and an idle codeword identified by the zero-bit-loaded NCP, and the idle codeword includes a data sequence used for channel parameter estimation. The CM can estimate a channel parameter of the downlink channel based on a data sequence in an obtained zero-bit-loaded symbol of the second data frame and the data sequence in the zero-bit-loaded symbol of the first data frame.

Abstract: The present disclosure relates to methods, devices, and systems for invoking a capability of another device. In one example method, a source end device requests capability information of a sink end device. The sink end device sends the capability information to the source end device. The source end device sends first content and first request information to the sink end device when detecting a first operation of a user, where the first request information is used to request the sink end device to process the first content by using a first function. The sink end device processes the first content based on the first request information by using the first function, and sends a processing result of the first content to the source end device. The source end device prompts the user with the processing result.
