We study a three-node network with a full-duplex base-station communicatingwith one uplink and one downlink half-duplex node. In this network, bothself-interference and inter-node interference are present. We use anantenna-theory-based channel model to study the spatial degrees of freedom ofsuch network, and study if and how much does spatial isolation outperformstime-division (i.e. half-duplex) counterpart. Using degrees of freedomanalysis, we show that spatial isolation outperforms time division, unless theangular spread of the objects that scatters to the intended users is overlappedby the spread of objects that back scatters to the receivers.
