and the second sending module is configured to send the second target data to the radio frequency front-end device when the level state is a third state.
8. The apparatus of claim 7, wherein the detection module comprises:
an acquisition unit configured to acquire a level of the TDD signal;
a first determining unit, configured to determine a level state of the TDD signal as the first state when it is detected that the level is in a state of maintaining a high level, where the first state is used to indicate a time instant when the TDD signal is in the high level;
a second determining unit, configured to determine, when it is detected that the level is in an increasing state, that the level state of the TDD signal is the second state, where the second state is used to indicate that the TDD signal is at a rising edge time;
a third determining unit, configured to determine, when it is detected that the level is in a reduced state, that the level state of the TDD signal is the third state, where the third state is used to indicate that the TDD signal is at a falling edge time.
9. A computer-readable storage medium, in which a computer program is stored, wherein the computer program is arranged to perform the method of any of claims 1 to 6 when executed.
10. An electronic device comprising a memory and a processor, wherein the memory has stored therein a computer program, and wherein the processor is arranged to execute the computer program to perform the method of any of claims 1 to 6.
