link adaptation approach, named CQI averaging herein, is proposed in this paper. In this approach, a number of consecutively received CQI reports from UE are mapped to equivalent Signal to Interference Ratio (SIR) values and passed through a moving average filter. The resulting average is used to derive the CQI index (named Average CQI herein) to be(More)
—Recently proposed universal filtered multi-carrier (UFMC) system is not an orthogonal system in multipath channel environments and might cause significant performance loss. In this paper, we propose a cyclic prefix (CP) based UFMC system and first analyze the conditions for interference-free one-tap equalization in the absence of transceiver imperfections.(More)
In this paper, the efficiencies of different interference coordination schemes are evaluated for emerging wireless networks and the possible impact on intra-cell scheduling is studied through extensive simulations. The results show that pure fractional frequency reuse can provide similar improvement in the ceD-edge throughput compared to power coordinated(More)
