1. A signal transmission method, wherein a first signal and a second signal work at the same time and share an antenna, wherein the first signal and the second signal have a shared band, a radio frequency front-end comprising the antenna, and the antenna is configured to receive and send a mixed signal of the first signal and the second signals and the method comprising:
determining, by a controller, that a priority of the first signal is higher than a priority of the second signal; when the first signal and the second signal work at the same time, determining whether a signal status of the first signal with a higher priority satisfies a service requirement; and if the service requirement is not satisfied, guiding the mixed signal of the first signal and the second signal that is received by the antenna to a processing back-end of the first signal by using a single-pole double-throw switch; or if the service requirement is satisfied, guiding the mixed signal of the first signal and the second signal that is received by the antenna to a power splitter by using a single-pole double-throw switch, and separately transferring 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. |
