Long Term Evolution (LTE) is a step towards the 4th generation (4G) of radio technologies designed to increase capacity and speed mobile wireless access. In Release 8, LTE was standardized by 3GPP as successor Universal Mobile Telecommunication System (UMTS).Before full commercial deployment LTE, downlink SNR CQI mapping for different multiple antenna techniques can be enormous significance operators. Such vital RF parameters should tuned before full-fledged launch. Adaptive Modulation...
The Fractional Frequency Reuse (FFR) is a resource allocation technique that can effectively mitigate inter-cell interference (ICI) in LTE based HetNets and it promising solution.Various FFR schemes have been suggested to address the challenge of femtocell systems.In this paper, we study scopes mitigation capacity improvement.We propose scheme gradually varies frequency share with distance from eNodeB for both macrocells femtocells order attain better utilization resources.This performed...
Over the past few decades, development of cellular communication technology has spanned several generations in order to add sophisticated features updated versions. Moreover, different high-frequency bands are considered for advanced generations. The presence like 4G and 5G is driven by rising demand a greater data rate better experience end users. However, because 5G-NR operates at high frequency significant propagation, atmospheric fluctuations temperature, humidity, rain might result...
Abstract—HARQ is a stop and wait protocol supporting soft combination of retransmitted data which used for facilitating fast error detection correction. In Long term Evolution (LTE), HARQ implemented by MAC level module called entity. The justification retransmissions lies in recovering correctly, though they consume radio resources. this paper, it proposed that the maximum number downlink may be limited order to save resources UEs with poor link LTE. Adequate simulation results LTE...
LTE-A present deployment strategies are likely to overcome the User Equipment (UE) performance degradation, in certain parts of topology incorporated with coverage block holes, due presence high rise buildings. It also promises serve increase user density, which otherwise results capacity exhaustion macro cells. addresses these challenges new features such as small cell and femto its recent releases. Small is a low-cost alternative rural hard-to-reach areas installation at strategic points...
A discontinuous reception (DRX) operation is included in the Long Term Evolution (LTE) system to achieve power saving and prolonged battery life of user equipment. An improvement DRX usually leads a potential increase packet delay. optimum configuration depends on current traffic, which not easy estimate accurately, particularly for non-real-time applications. In this paper, we propose novel way vary cycle length, avoiding continuous estimation data traffic when only applications are running...
The heterogeneous networks (HetNets) are regarded as a promising solution in LTE-Advanced for ubiquitous and cost effective broadband user experience.But there challenges to support seamless mobility Het-Nets, especially, when the speed is high.In this paper, we investigate these study scopes address them improvement of cell edge performance.The indicates requirement enhanced versatile controllability over adaptation switching parameters that simultaneously depends on variation speeds,...

A heterogeneous network (HetNet), typically a combination of macrocells and small cells, is popular solution for Long Term Evolution (LTE) based 4G or 5G technologies as it can provide ubiquitous cost-effective broadband user experience with higher capacity.However, the interference issues are more complicated in LTE HetNets.The mobile unknown locations User Equipment (UEs) add further difficulties to management uplink spectrum where this separate range from downlink FDD same but on specific...
Non-Orthogonal Multiple Access (NOMA) is a popular solution for supporting high number of users and along with significant bandwidth in 5G cellular communication. By using technique called cooperative relaying, the same data sent to all users, one user can relay other. In order provide enough power energy harvesting techniques have been introduced Simultaneous Wireless Information Power Transfer (SWIPT) coming prominence recent times. this paper, analysis has made comparing two different...
Fifth-generation (5G) introduces the use of millimeter waves (mmWave) in cellular technology, and thus poses a great challenge proper radio coverage.
