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: This application relates to a communication method and apparatus. An activation command is received from a network device, where the activation command indicates to activate a first secondary carrier, and the first secondary carrier is one of secondary carriers of a terminal device. When the first secondary carrier is known, whether to adjust AGC of the first secondary carrier is determined based on a measurement cycle of the terminal device for the first secondary carrier, where a temporary reference signal is used to adjust the AGC of the first secondary carrier. A first temporary reference signal is received from the first secondary carrier, and time-frequency synchronization with the first secondary carrier is performed based on the first temporary reference signal.

Abstract: A positioning signal processing method includes receiving positioning reference signal (PRS) configuration information from a positioning device. A PRS is received as a PRS resource set. Each PRS resource set includes one or more PRSs. One access network device corresponds to one or more PRS resource sets. The positioning signal processing method further includes determining PRS time domain information based on the PRS configuration information. The time domain information includes a periodicity (P) of the PRS and a symbol length of the PRS in the P. The positioning signal processing method further includes receiving a plurality of PRSs based on the PRS time domain information.

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: This application provides an inter-frequency measurement resource and/or time determining method and an apparatus. When a length of each idle time domain resource is greater than or equal to a first threshold, or when a cycle of discontinuous reception configured by a network device is greater than or equal to a second threshold, a terminal device uses a part of the idle time domain resource as a first resource that is in the idle time domain resource and that can be used to perform inter-frequency measurement. The terminal device determines, based on the first resource in each idle time domain resource, a resource and/or time used to perform the inter-frequency measurement.

Abstract: A network routing device, a network data transmission method, and a network access device. The network routing device's first network transmission processing module is configured to convert a received data signal into at least two baseband signals, send one baseband signal to a first radio frequency unit, and send another baseband signal to a first wired communication module. The first radio frequency unit converts the baseband signal into a radio frequency signal and sends the radio frequency signal by using a first antenna, and the first wired communication module converts the baseband signal into a network signal that can be transmitted in a wired transmission medium and sends the network signal to the wired transmission medium for transmission. According to the network routing device, a signal can be transmitted in both a wired manner and a wireless manner. This improves signal transmission reliability.
