A signal transmission method and system, and a controller are disclosed. The controller controls a single-pole double-throw switch by determining whether a signal status of a first signal with a higher priority satisfies a service requirement; and if the service requirement is not satisfied, guides a mixed signal of the first signal and a second signal that is received by an antenna to a processing back-end of the first signal by using the single-pole double-throw switch; or if the service requirement is satisfied, guides a mixed signal of the first signal and a second signal that is received by an antenna to a power splitter by using the single-pole double-throw switch, and separately transfers the mixed signal of the first signal and the second signal to a processing back-end of the first signal and a processing back-end of the second signal by using the power splitter. In this way, two signals having a shared band can share an antenna when the two signals work at the same time, and a service requirement of a signal with a higher priority can be ensured. Therefore, user experience is improved. |
