Abstract: 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.

Abstract: A resource determining method includes that a first terminal obtains transmission information from a second terminal, wherein the transmission information is used to indicate a first sidelink resource. The first terminal determines a second sidelink resource according to the transmission information, wherein a time range of the second sidelink resource does not overlap that of the first sidelink resource. The first terminal sends a first data to the second terminal on a sidelink resource of the second sidelink resource, wherein the first sidelink resource comprises a sidelink resource on which a second data is received by the second terminal.

Abstract: A measurement configuration method and an apparatus are provided. The method includes: A network device sends first information to a terminal device. The first information includes configuration information of an SCC. The network device sends second information to the terminal device. The second information includes configuration information of a first measurement window, and the second information is used to enable the terminal device to switch, when supporting CA, from performing cell measurement in a measurement window-free measurement manner to performing cell measurement by using the first measurement window. A carrier included in the CA includes the SCC configured based on the first information. According to the foregoing method, after the network device configures the SCC, the terminal device may switch, based on the second information, from performing cell measurement in the measurement window-free measurement manner to performing cell measurement by using the first measurement window.
