A measurement configuration method includes A network device that sends first information to a terminal device. The first information includes configuration information of a secondary component carrier (SCC). The network device sends second information to the terminal device. The second information includes configuration information of a first measurement window and enables the terminal device to switch, when supporting carrier aggregation CA, from performing cell measurement in a measurement window-free measurement manner to performing cell measurement using the first measurement window. A carrier included in the CA includes the SCC configured based on the first information.

An application processor sends a TCP packet to the modem, where the TCP packet is used by the modem to generate a wireless protocol data packet corresponding to the TCP packet, so that the modem sends the wireless protocol data packet to a base station. The application processor receives first status information from the modem, where the first status information is status information of the wireless protocol data packet or status information of the TCP packet. The application processor determines, based on the first status information, whether the TCP packet is successfully sent to the base station. If the TCP packet is successfully sent to the base station, the application processor starts a retransmission timer corresponding to the TCP packet. If the TCP packet is not successfully sent to the base station, the application processor sends the TCP packet to the modem again.
