Wherein, when neither the first 5G radio frequency signal nor the second 5G radio frequency signal includes communication service data, the four first antennas 203 are used to transmit the first time period of each transmission cycle. For a 5G radio frequency signal, the four first antennas 203 are further configured to transmit the second 5G radio frequency signal in the second time period of each transmission period.

For the second 5G radio frequency signal, the second antenna ANT5 is vacant. At this time, the first time period includes time sequences T1 and T3, and the second time period includes time sequences T2 and T4.

At this time, the first time period includes time sequences T1 and T2, and the second time period includes time sequences T3 and T4.
