Abstract
In this paper, initially the issues of spectrum allocation among macro (or “licensed”) and Femto (or “unlicensed”) users in an Orthogonal Frequency Division Multiple Access (OFDMA) based dual-layer femtocell networks have dealt with. This research contribution leads to basic coin in the design of next generation (5G) wireless networks. This manuscript exemplifies the trade-off issues of energy efficiency (EE) and spectral efficiency (SE) with both cooperative and non-cooperative architecture in cognitive femtocell networks. The pivotal concepts for each technology are described along with their potential impact on 5G and the research challenges that remain. Further, the trade-off between EE and SE is reposed with respect to the state of the art. The obtained insightful observations from the trade-off analysis of EE ans SE can lead to provide design guideline for 5G wireless Networks.
Highlights
A forward movement of research will demand basic modifications in the design of fourth generation (4G) cellular architecture
The trade-off between EE and spectral efficiency (SE) has been investigated for the cognitive femtocell networks
From the above discussion and from the architectural consideration earlier, we conclude that native support of femtocell in 5G requires radical changes at both different edge network topologies and architectural level
Summary
A forward movement of research will demand basic modifications in the design of fourth generation (4G) cellular architecture. Femtocell makes various openings to meet the goal that regulators set out to obtain [15], such as: Revamped Access: Femtocells yield a price effective matters of enhancing consumer access to mobile services They enhance coverage in a difficult to reach indoors without the large deployment of outdoor base stations (BSs) [16]. When there is no separation between the indoors and outdoors, they are strongly coupled and the inter-tier interference is at its maximum, if the buildings are situated near to the middle of the macrocell In this matter including femtocells to the building (with the same carrier frequency) is like including cells to the middle of another cell (Fig. 1(a)).
