The disclosure provides example communication methods and apparatuses. One example method includes that a terminal device receives first transmission capability information of a first universal subscriber identity module (USIM) from a first access network device corresponding to the first USIM, where the first transmission capability information of the first USIM comprises single communication duration of the first USIM and a single communication periodicity of the first USIM, and the terminal device includes the first USIM and a second USIM. The first terminal device sends a first response message to the first access network device based on a transmission capability requirement of the first USIM and a service of the terminal device, where the first response message indicates that use of the first transmission capability information of the first USIM is either accepted or rejected, or the first response message comprises second transmission capability information of the first USIM.
