Multi-cell Device-to-Device Communications: A Spectrum Sharing and Densification Study. (arXiv:1711.03498v1 [cs.IT])
来源于:arXiv
One of the most significant 5G technology enablers will be Device-to-Device
(D2D) communications. D2D communications constitute a promising way to improve
spectral, energy and latency performance, exploiting the physical proximity of
communicating devices and increasing resource utilization. Furthermore, network
infrastructure densification has been considered as one of the most substantial
methods to increase system performance, taking advantage of base station
proximity and spatial reuse of system resources. However, could we improve
system performance by leveraging both of these two 5G enabling technologies
together in a multi-cell environment? How does spectrum sharing affect
performance enhancement? This article investigates the implications of
interference, densification and spectrum sharing in D2D performance gain. The
in-band D2D approach, where legacy users coexist with potential D2D pairs, is
considered in a multi-cell system. Overlay and underlay spectrum sharing
