One port is used to receive and transmit signals while the other is used to receive signals only. The RX channel functions as follows: 1. Antennas of the two-port antenna system receive weak signals from UEs and send them to the MAFU through feeders. 2. In MAFUs, the duplexers filter the signals from the receiving-and-transmitting port and the low noise amplifiers (LNAs) amplify the signals. Then the UL signals are sent to the MTRU. 3.
