“…The same approach can also be effective for urban scenarios, where dense AP deployments would encounter installation difficulties, such as a large number of utility poles, cables etc. [39,40]. Wireless in-band backhaul was also evaluated as candidate technique for throughput increase in massive MIMO systems [41].…”

Capacity overprovisioning in mobile networks leads to underutilization of network resources and thus inefficient operation from a power consumption perspective. In addition, as operators constantly evolve their networks to denser heterogeneous layouts, with overlaying macrocellular base stations coexisting with numerous smaller cells, to cope with upcoming increase in peak mobile data traffic, the energy consumption of mobile networks will continue to grow in the next years. In this context, although backhaul connections can be responsible for tremendous power consumption, the corresponding study is usually neglected in most of the recent energy related literature. An approach for fast and low cost connectivity of dense microcellular sites is the deployment of wireless in-band backhaul links via existing macrocellular base stations. In this paper, we consider this wireless in-band backhaul approach, where access and backhaul links share the same frequency spectrum, and examine joint energy efficient resource optimization on both links. We introduce an iterative low-complexity polynomial backhaul-aware heuristic, which directs traffic to the most energy efficient network resources, and compare it against i) an exhaustive search method that provides optimum results, Engineering, Vol. 6 4, 337-368. doi: 10.13052/jge1904-4720.641 c 2017 338 G. Kyriazis and A. Rouskas ii) a previously proposed reference algorithm, and iii) ordinary Full Operational Topology (FOT) network, where no energy aware technique is applied. From the results obtained, we conclude that our heuristic achieves high energy efficiency gains in all scenarios examined, while wireless in-band backhaul method proved a solid choice for this purpose.

“…System performance evaluations by deploying RNs in LTE-Advanced systems have been performed in indoor [213], urban [214], and suburban [215,216] deployments. An evaluation has been done in an LTE-Advanced network in London, UK and the downlink channels performance of RNs was compared with the use of micro base stations [217]. In this study, inband relay was considered and the user data rate of 1024 kbps was set as the minimum target.…”

Long Term Evolution Advanced (LTE-Advanced) is the next step in LTE evolution and allows operators to improve network performance and service capabilities through smooth deployment of new techniques and technologies. LTE-Advanced uses some new features on top of the existing LTE standards to provide better user experience and higher throughputs. Some of the most significant features introduced in LTE-Advanced are carrier aggregation, enhancements in heterogeneous networks, coordinated multipoint transmission and reception, enhanced Multiple Input Multiple Output (MIMO) usage and deployment of relay nodes in the radio network. Mentioned features are mainly aimed to enhance the radio access part of the cellular networks. This survey article presents an overview of the key radio access features and functionalities of the LTE-Advanced radio access network, supported by the simulation results. We also provide a detailed review of the literature together with a very rich list of the references for each of the features. An LTE-Advanced roadmap and the latest updates and trends in LTE markets are also presented.

“…We assume to perform an 'In-band' relay solution, operating on the assigned system UL/DL frequencies, meaning that links between the base station and the relay nodes are on the same carrier frequency as the link between the base station and the user equipment i.e. the BS-RN link and the BS-UE link are on the same carrier frequency [12]. Each i − th base station is equipped with two antennas:…”
