“…In this case, let t a be the quota of frame resource blocks dedicated to RL and DL, and τ the quota of frame resource blocks devoted to transmission on the BL, so that t a + τ = 1. Resources belonging to quota τ are used by the eNBs on the BL to serve their controlled RNs, and they are orthogonal to resources belonging to quota t a [28], [29], [30]. Orthogonality is necessary because of the half-duplex nature of RNs.…”

This paper studies the performance of two traditional schedulers, Proportional Fair (PF) and Round Robin (RR), in the context of relay-enhanced LTE-A networks. These two schedulers are indeed natural candidates for implementation in relays nodes (RN) and, following the results obtained in singlehop networks, mobile operators could be tempted to adopt PF because of the good trade-off it offers between cell capacity and fairness. Based on a statistical throughput evaluation model, we show that this is not necessarily the right option. The number of RNs, their locations in the cell, and the backhaul link quality have indeed a decisive influence on the scheduler choice. In some scenarios, it is even not desirable to deploy relays as they degrade the network performance compared to the no relay case. For the purpose of performance evaluation, we develop a realistic and computationally tractable statistical network model that takes into account fast fading, multiple interferers, cell range expansion bias, backhaul link quality, and traffic load. We also propose an optimization of the radio frame structure and a sub-optimal RN placement scheme in order to fairly compare RR and PF.

“…Hence, this technique is suitable for large scale network planning where the cost efficiency is an important issue, and it can help undeveloped countries to implement the infrastructures with lower time complexity and less construction cost. Some other methods and strategies regarding the site planning and RN placement were introduced in [202][203][204][205]. The effects of the antenna height on the propagation channel in relaying were also discussed in [206,207].…”

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.

“…Reference [27] addresses the optimal relay placement issue for purpose of coverage extension by considering both UL and DL transmission scenarios. Reference [28] prove the importance of relay nodes site planning by proposing and analyzing two approaches for relay nodes sites planning. The first approach is location selection and the second is serving cell selection.…”

Abstract-LTE Advanced is a well designed system that meets the requirements of 4G cellular systems. Its standard specification has been lately released. One of its main features is supporting relaying topology inspired from ad hoc multihop networks. This paper is a survey upon the relaying architecture of LTE Advanced standard based on 3GPP Release 10 specifications. A comparison with other relaying architectures, i.e. IEEE 802.16m and IEEE 802.11s is handled. The originality of this work is in involving comparison with multihop architecture supported by IEEE 802.11s based wireless mesh networks. Several similarities are noted and differences are pointed out.
