Abstract
This application provides a downlink transmitting system and a switching method. An example downlink transmitting system includes at least one digital intermediate frequency module group, at least one Tx port group, a plurality of power amplifiers (PAs), at least one switching switch, and an antenna array. The plurality of PAs are connected to the antenna array. The plurality of PAs are connected to all Tx ports included in the downlink transmitting system in a one-to-one correspondence. The at least one digital intermediate frequency module group is in a one-to-one correspondence with the at least one Tx port group. Each of the at least one Tx port group is connected to each digital intermediate frequency module in a corresponding digital intermediate frequency module group through one of the at least one switching switch. The each of the at least one Tx port group includes a plurality of Tx ports.
