Abstract—Long Term Evolution (LTE) is a step towards the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile wireless access. In Release 8, LTE was standardized by 3GPP as the successor of the Universal Mobile Telecommunication System (UMTS).Before full commercial deployment of LTE, downlink SNR to CQI mapping for(More)
In case of Long Term Evolution (LTE), the scheduler in the MAC layer of the eNodeB allocates the available radio resources among different UEs in a cell through proper handling of priority. The scheduling method used largely impacts the throughput of individual users as well as throughput of the cell. It is worthwhile to check on the throughput conditions(More)
The Fractional Frequency Reuse (FFR) is a resource allocation technique that can effectively mitigate inter-cell interference (ICI) in LTE based HetNets and it is a promising solution. Various FFR schemes have been suggested to address the challenge of interference in femtocell systems. In this paper, we study the scopes of interference mitigation and(More)
Long Term Evolution (LTE) is the latest and most enhanced broadband wireless access (BWA) technology. LTE is the latest standard in the mobile network technology tree that previously realized the GSM/EDGE and UMTS/HSxPA technologies. LTE is expected to ensure 3GPP's competitive edge over other cellular technologies. The standardization process of LTE(More)
HARQ is a stop and wait protocol supporting soft combination of retransmitted data which is used for facilitating fast error detection and correction. In Long term Evolution (LTE), HARQ is implemented by MAC level module called HARQ entity. The justification of HARQ retransmissions lies in recovering data correctly, though they consume radio resources. In(More)
Microstrip antennas are low in profile and light in weight and they are now developed for many applications. The main difficulty of the microstrip antenna is its narrow bandwidth. Several modern applications like satellite communications, remote sensing and multi-function radar systems will find it useful if there is a dual band antenna operating from a(More)
The online applications for street information have gained much popularity and wide use recently. The growing data rate of cellular services at affordable cost is supporting such applications. The Long Term Evolution (LTE) and its later version, LTE-Advanced (LTE-A) are now the most promising technologies for the cellular services. The street information,(More)
Automation of radio network management is a key determination to work reduction for wireless operators. Self configured and self optimized network is a major feature for Long term Evolution (LTE). This paper proposes a procedure for self optimization and continuous update procedure of GSM neighbor cell list in E-UTRAN system. This method makes use of mobile(More)
