NEC proposed three features for LTE Advanced:
1. Adaptive uplink multiple access using DFT-s-OFDM with spectrum division control and adaptive selection of DFT-s-OFDM and OFDM to achieve a good tradeoff between cell throughput and coverage.
2. Advanced SON solutions for radio optimization (SONv2) using self-organizing techniques to reduce costs and maintain performance, such as self-deployment of eNodeBs and self-coordinating interference management.
3. Advanced RRM solutions for full femtocell deployments to address challenges like interference between macro and femto cells through techniques like RF selection and power control of femto cells.
As a consequence of the proliferation of smart phones and tablets, data traffic is growing significantly, both on the radio access links and the backhaul infrastructure of mobile operators’ networks. And although LTE and LTE Advanced offer higher data traffic throughput than that of 3G, given to their wider allocated bandwidths, the combined capacities of even these networks is not sufficient to meet projected future capacity demands.
The conventional solution to increasing the capacity of LTE mobile networks includes splitting macro-cells and/or adding more sites. Both of these solutions require high CAPEX and OPEX, so mobile operators are seeking new and cost effective ways of increasing their network capacity. One solution is to deploy small-cell base stations (BSs) within their existing macro-cellular networks, an approach referred to as Heterogeneous Networks.
It is well known that a HetNet not only increases the network capacity, but also provides better coverage and enhances the user’s experience. These benefits are achieved by offloading data traffic dynamically from MCBSs to SCBSs using an algorithm based on several parameters such as the characteristics of the traffic, the required QoS and network
NETWORK ENERGY SAVING TECHNOLOGIES FOR GREEN WIRELESS ACCESS NETWORKSMadhav Thekkedath
Now a day smart phone users are increased and the energy consumption problem in mobile industry has become crucial. For the growth of mobile industry energy efficiency of the system must be improved. In order to improve the methods of network energy usage usually reduction of the Base Stations are to be employed.
The mobile industry faces a critical energy consumption challenge. By 2014 smart phones will exceed 1.82 billion units and surpass PCs as the most common web access devices. That’s why it is one of the important things. As all know that a smart is mainly for easy access to the network at anytime and anywhere. So it employs powering up all the Radio Base Stations (RBS’s) at maximum power. Since there are more number of service providers competition exist at the field of telecommunication. So it yields in more energy consumption to get monopoly among them. In the field of engineering, a system is usually designed to transform energy to useful work. Energy Efficiency can therefore be defined as the ratio of useful work to the total supplied energy. The useful work in a communication system refers to the effort to deliver modulated signals for information exchange. The definition of Energy Efficiency varies according to measured objects. There are two basic methods to measure Energy Efficiency. One way is to define Energy Efficiency as the ratio of efficient output power/energy to total input power/energy. This definition is widely used by systems and components such as power supply, Power Amplifiers, and antennas. The other way defines Energy Efficiency as the performance per unit of energy consumption.
The seminar gives a brief description about the methods to manage the network energy even when the on time access to network by mobile phones. Also gives a summary about existing and latest methodologies about the management in RBS’s.
Radio Resource Management for Eicic, Comp, Relaying and Back-hauls Techniques...ijwmn
Frequency reuse in cells is one of the strategies that LTE (Long Term Evolution) uses to maximize the spectrum efficiency. However, it leads to an interference among the cells, especially at the cell edges where the probability for a cell-edge user to be scheduled on a resource block that is being transmitted by the neighbouring cell is high; consequently, the interference is high. In-order to mitigate Inter-Cell Interference (ICI), Inter-Cell Interference Coordination (ICIC) was proposed by the Third Generation Partnership Project (3GPP) standards for the LTE network, and later on, the enhanced Inter-Cell Interference Coordination (eICIC) was proposed for the LTE-Advanced network. ICIC reduces cell-edge interference on traffic channels from neighbouring cells by the use of three interference reduction schemes that works in the power and frequency domain, and they are based on lowering the power of some channels to limit their reception to the users that are close to the base station, and by reducing the chance of frequency overlap. eICIC was proposed to handle ICI in Heterogeneous Network (HetNet) deployments. It reduces the interference on both the traffic and control channels. It uses power, frequency and also time domain to mitigate intra-frequency interference in HetNets. Another technique that was proposed by the 3GPP for the LTE-Advanced network that can reduce the ICI and improve the cell average and cell-edge user throughput is the Coordinated Multi-Point (CoMP) transmission/reception technique. CoMP can increase the cell average and cell edge user throughput in both the uplink and downlink transmission by joint scheduling and data processing in multiple cells/eNBs. Another technique that was proposed by the 3GPP for the LTE-Advanced network that can improve the LTE network coverage in difficult conditions is to deploy Relay Nodes (RNs). In this paper, we survey Radio Resource Management (RRM) for some of the techniques that are used with LTE-A. The included techniques in this paper are; the ICIC, eICIC, CoMP, Relaying and Back-hauls. We start by explaining the concepts of these techniques. Then, by summarizing the radio resource management approaches that were proposed in the literature for these techniques. And finally, we provide some concluding remarks in the last section.
