  • Publication number: 20220086875
    Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. In the method, a terminal may send, to a network device, a quantity of radio frequency channels supported on each of a plurality of carriers when the terminal performs uplink transmission on the plurality of carriers in TDM mode. In this method, the terminal may report, to the network device, a quantity of radio frequency channels used on each carrier when the terminal performs uplink transmission in TDM mode, so that the network device can configure, for the terminal based on an actual capability of the terminal, the quantity of radio frequency channels used on each carrier in TDM mode. This improves an uplink transmission capability of the terminal.

  • Publication number: 20210274513
    Abstract: An uplink determining method and an apparatus. An access network device may determine, based on signal quality of a downlink frequency band corresponding to a supplementary uplink (SUL) or signal quality of a frequency band of an SUL, the signal quality of the frequency band of the SUL, to accurately evaluate coverage performance of the SUL; and after determining the signal quality of the frequency band of the SUL, may determine whether to perform transmission on the supplementary uplink, to avoid a case in which the access network device blindly indicates a terminal to perform transmission on the supplementary uplink when signal quality of the supplementary uplink is not measured, leading to transmission of the terminal on the supplementary uplink with poor coverage and even a failure, thereby improving reliability and a transmission rate of uplink transmission and improving user experience.

  • Publication number: 20210274483
    Abstract: Embodiments of this application provide an uplink switching solution. In this solution, switching is performed between an SUL and an NUL, and a switching time period for the switching between the SUL and the NUL is longer than 0 microseconds. Therefore, the SUL and the NUL can share a radio frequency channel, so that the shared radio frequency channel can be switched between the SUL and the NUL, thereby improving utilization of the radio frequency channel, and improving uplink transmission performance.

  • Patent number: 11006473
    Abstract: A first access network device receives an addition request message from a second access network device. The first access network device determines a third uplink carrier used by a terminal to send a preamble to the first access network device, and sends an addition request acknowledgement message to the second access network device. The addition request acknowledgement message includes carrier indication information. The carrier indication information indicates the third uplink carrier. The third uplink carrier is at least one of the first uplink carrier or a second uplink carrier. The second uplink carrier and the first uplink carrier belong to a same cell of the first access network device and the second uplink carrier is a supplementary uplink carrier.

  • Patent number: 9987924
    Abstract: Aspects of the disclosure relate to a method of controlling an HMI-apparatus for providing information to a driver of a vehicle for aiding driver control of a vehicle when the vehicle is wading in a body of water. The method includes determining a measured depth of water about the actual vehicle and determining a display depth, dependent upon the measured depth of water. The method also includes measuring a lateral and/or longitudinal gradient of the actual vehicle and selecting a display vehicle position from a limited number of available options of display vehicle positions based upon the measured lateral and/or longitudinal gradient of the actual vehicle. In this way the HMI-apparatus can output a simplified picture of the actual vehicle scenario which may be easier for the driver to assimilate.
