Downlink Energy Efficiency of Power Allocation and Wireless Backhaul Bandwidth Allocation in Heterogeneous Small Cell Networks. (arXiv:1710.02942v1 [cs.IT])
来源于:arXiv
The widespread application of wireless services and dense devices access have
triggered huge energy consumption. Because of the environmental and financial
considerations, energy-efficient design in wireless networks becomes an
inevitable trend. To the best of the authors' knowledge, energy-efficient
orthogonal frequency division multiple access heterogeneous small cell
optimization comprehensively considering energy efficiency maximization, power
allocation, wireless backhaul bandwidth allocation, and user Quality of Service
is a novel approach and research direction, and it has not been investigated.
In this paper, we study the energy-efficient power allocation and wireless
backhaul bandwidth allocation in orthogonal frequency division multiple access
heterogeneous small cell networks. Different from the existing resource
allocation schemes that maximize the throughput, the studied scheme maximizes
energy efficiency by allocating both transmit power of each small cell base
