If I have a full duplex relay, can half-duplex devices effectively communicate with this relay? Also, can interference cancellation be applied to the relays or devices in this case? To be more specific: I am considering two half-duplex D2D (device-to-device communication) devices which would communicate using a full duplex relay (say special devices equipped with full duplex capabilities). If otherwise (i.e they should all be full duplexes), I guess the number of transmitting full duplex devices must be equal to full duplex relays.
It appears a simple question but googling it have not helped me.
