AI summary
A method for transmission compatible with two types of TDD switch signals includes: receiving a downlink TDD switch signal; performing a power-on detection on the downlink TDD switch signal; in response to a successful power-on detection, generating a standard switch signal corresponding to the downlink TDD switch signal; receiving an information of a successful power-on detection and the standard switch signal; comparing the downlink TDD switch signal with the standard switch signal; in response to that a number of abnormal values between the downlink TDD switch signal and the standard switch signal is less than a set value N, outputting a first downlink power switching signal, a first uplink power switching signal, a second downlink power switching signal, and a second uplink power switching signal related to the downlink TDD switch signal.
