Abstract-Full-duplex radio technology is becoming mature and holds potential to boost the spectrum efficiency of a point-topoint wireless link. However, a fundamental understanding is still lacking, with respect to its advantage over half-duplex in multi-cell wireless networks with contending links. In this paper, we establish a spatial stochastic framework to analyze the mean network throughput gain from full-duplex, and pinpoint the key factors that determine the gain. Our framework extends classical stochastic geometry analysis with a new tool-set, which allows us to model a trade-off between the benefit from concurrent full-duplex transmissions and the loss of spatial reuse, particularly for CSMAbased transmitters with random backoff. The analysis derives closed-form expressions for the full-duplex gain as a function of link distance, interference range, network density, and carrier sensing schemes. It can be easily applied to guide the deployment choices during the early stage of network planning.
In REF , Wang et al. established a spatial stochastic framework to investigate the network throughput gain of FD in multi-cell networks with contending single-hop links.
