By introduction of relay nodes, LTE-Advanced can provide enhanced coverage and capacity at cell edges and hot-spot areas. The authors have been researching the issue of power saving in mobile communications technology such as WiMax and Long Term Evolution (LTE) for some years. Based on the previous idea of load-based power saving, two strategies each with associated schemes to integrated relay nodes and user equipment in power saving are proposed in the paper. Simulation study shows the benefit of the proposed schemes in terms of better power saving than the standard-based scheme at the cost of moderately increased delay. Extended discussion about the impact of different load distribution among user equipments and the impact of a worse backhaul link on power saving is also presented in the paper.

“…If the same frequency band is used for the both links and the split is done in the time domain, then it is called an inband relay. There are several studies for the appropriate resource sharing between backhaul and access links and mitigation of interference using the proper resource scheduling techniques [171][172][173][174][175][176][177][178][179][180][181][182][183][184]. CA feature can provide more flexible resource allocation in relaying networks [185,186].…”

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.

“…This paper focuses on backhaul subframes, often hardly treated compared with access subframes, in most works. Resource allocation (RA) in backhaul subframes has been addressed in the literature from different perspectives [3][4][5][6][7][8][9][10]. In [3][4]6] the proposals are based on fixed frequency partition schemes and they focus on strategies to share the available resources among RNs served by the DeNB.…”

“…In [3][4]6] the proposals are based on fixed frequency partition schemes and they focus on strategies to share the available resources among RNs served by the DeNB. In [5][6][7]10] the proposals are focused on computing the resource demands of each relay considering several criteria. In [3][4][5][8][9][10] the RA algorithm distributes the resources between direct and backhaul links.…”

“…A similar option is also included in [6], where the authors assume that in backhaul subframes only RNs are assigned and they focus on various techniques to allocate the available resources to the different RNs belonging to the same DeNB. In [7], the resource demand of each RN in backhaul subframes is estimated considering the relay buffer level, and the aim is to keep the relay buffer size near zero. RA in [8][9] includes how to split the resources at DeNB to serve direct and backhaul links, in addition to several QoS scheduling strategies for backhaul links in order to satisfy the QoS constraints of rUEs.…”

Relaying is considered in LTE-A networks as a promising solution to increase the capacity and improve the coverage. Resource sharing among different nodes and links and inter-cell interference coordination (ICIC) are challenging issues to obtain a real performance gain linked to relay deployments. This paper focuses on Type 1 half-duplex inband relaying. We propose a dynamic resource allocation (RA) and ICIC algorithm for backhaul subframes, in which the resources allocated to each RN in its backhaul link are dynamically adjusted, considering the aggregate traffic demand of its users in heterogeneous load distributions among RNs. The aim is to achieve a fair resource distribution among RNs, using efficient coordinated frequency reuse schemes, which not only reduce ICI but also minimize the impact on the bandwidth availability of macrocell users.
