  • Publication number: 20200280899
    Abstract: Example communication methods and apparatus are described. One example communication method includes receiving broadcast information by a terminal device. The broadcast information includes a first parameter and a second parameter that are for a first cell. The first parameter is used for cell selection or cell reselection performed by a terminal device that supports supplementary uplink (SUL) carrier transmission, and the second parameter is used for cell selection or cell reselection performed by a terminal device that does not support SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the first parameter when the terminal device supports SUL carrier transmission. The terminal device performs cell selection or cell reselection based on the second parameter when the terminal device does not support SUL carrier transmission.
