Hybrid Lte- Fractional Frequency Reuse (ffr) in User Mobility Environment
Long Term Evolution (LTE) is broadly available to the world. The upcoming trend in LTE-Advanced (LTE-A) emphasizes the enhancement in spectrum efficiency, capacity and cell-edge user throughput and thus highlights the small cell technologies. With the advantage of small size, Femtocell is able to be deployed at "Died zone" and thus satisfying the service expectation particularly to cell-edge us...
متن کاملComparative Evaluation of Fractional Frequency Reuse (ffr) and Traditional Frequency Reuse in 3gpp-lte Downlink
3 Generation Partnership Project Long Term Evolution (3GPP-LTE) is focusing towards aggressive frequency reuse i.e. reuse of 1 so that we can get maximum number (all available spectrum) within a cell. Now, the major hindrance is co-channel interference which increases dramatically due to nearby adjacent co-channel cell and most especially for cell edge users. Traditional frequency reuse concept...
متن کاملInterference Mitigation Optimal Dynamic Fractional Frequency Reuse (OD-FFR) Scheme in LTE Networks
Fractional Frequency Reuse is an interference mitigation technique well suited for OFDMA system where the cell region is partitioned into two: inner cell region and outer cell region. In this paper we proposed an interference mitigation technique in LTE OFDMA femtocell system using Fractional Frequency Reuse (FFR) also system in order to improve performance of the system resource allocation is ...
متن کاملFractional Frequency Reuse in Integrated Femtocell/Macrocell Environments
Femtocells have a strong potential for increasing the efficiency, cell coverage and network capacity of next-generation mobile networks. In Long Term Evolution technology, the adaptation of Fractional Frequency Reuse techniques has been proposed in order to overcome the co-channel interference and augment the total throughput of the network. In this work, we propose a Fractional Frequency Reuse...
متن کاملA New Frequency Partitioning and Allocation of Subcarriers for Fractional Frequency Reuse in Mobile Communication Systems
Some OFDMA-based wireless commuication systems, e.g., Wireless Broadband Internet (WiBro) or Worldwide interoperability for Microwave Access (WiMAX), support frequency reuse of 1 to maximize spectral efficiency. One of the efficient methods to reduce co-channel interference (CCI) caused by frequency reuse is fractional frequency reuse (FFR). In this paper, we propose and validate a novel freque...
