On the throughput gain of device-to-device communications
2015 (English)In: ICT Express, ISSN 2405-9595, Vol. 1, no 2, 67-70 p.Article in journal (Refereed) Published
In an uplink underlaid device-to-device (D2D) cellular network, this paper considers its two aspects of throughput improvement. The two-fold gain comprises the throughput increase by offloading downlink cellular traffic to D2D communications, duplexing gain, and the increase by reusing uplink resources of D2D transmissions, capacity gain. Both impacts are investigated by exploiting stochastic geometry. On the basis of the analysis, a throughput optimal D2D operation guideline is provided for different network congestion environments.
