Full duplexer design where both Tx and Rx send and receive at the same time

Hi,
I am working on an project, which is to design a transceiver at 10GHz from 1.2V supply and using 45nm RF CMOS and where TX and RX occur concurrently at 10 GHz. I am a bit confused on the duplexer aspect of the design. From what I've read from IEEE papers, most duplexer designs use BPFs for the TX and RX and or time division multiple access (TDMA)/time division duplexer (TDD).
If both TX and RX send and receive at the same time, what method should be used to accomplish this? From my understanding, I should be using some sort of frequency division duplexer (FDD), but that implies that both TX and RX operate at different frequencies and I'm under the impression that both the TX and RX operate at 10GHz.
Any help is much appreciated.
Thank you
P.S. The professor hinted that we use CDMA. If that is the case, how would that change the design of the duplexer, if at all?
