The amount of mobile data traffic is more than doubling each year because of the increase in mobile video traffic and spread of smartphones. Although a recent survey has predicted that the annual rate of increase in global mobile traffic will gradually slow in the future, we have to develop effective technologies to cope with this continuously growing amount of mobile data traffic. The Long Ter...

We present a technique to treat systems with very many levels, like molecules, in non–LTE. This method is based on a superlevel formalism coupled with rate operator splitting. Superlevels consist of many individual levels that are assumed to be in LTE relative to each other. The usage of superlevels reduces the dimensionality of the rate equations dramatically and, thereby, makes the problem co...

With both small-cell LTE and Wi-Fi networks available as alternatives for deployment in unlicensed bands (notably 5 GHz), the investigation into their coexistence is a topic of active interest, primarily driven by industry groups. 3GPP has recently standardized LTE Licensed Assisted Access (LTE-LAA) that seeks to make LTE more co-existence friendly with Wi-Fi by incorporating similar sensing an...

Long Term Evolution (LTE) is a Quality of Service (QoS) provisioning wireless network for today’s technology and as well as for future demands. There is a high demand for better network performance over LTE network, either for real-time or non-real-time traffic. Specifically, the existing scheduling algorithms for real-time application, Exponential/Proportional Fair (EXP/PF), Proportional Fair ...

Long Term Evolution Advanced (LTE-A) technology is considered as the most possible candidate for next generation mobile communications. LTE-A networks offer high capacity and are specified and designed to accommodate small, high performance, power-efficient end-user devices. Similarly to its predecessor LTE, LTE-A incorporates inter-cell interference mitigation methods in order to mitigate inte...

In order to improve the wireless network performance, one of the most potential solutions is the use of a number of small size cells called femtocells. One of the facilitating technologies for LTE/ LTE-A (Long Term EvolutionAdvance) is the deployment of femtocellular network. As the number of femtocell increases, managing the radio resource becomes challenging due to the co existence of other f...

Deployment of new radio technologies in the mobile world has been steadily gaining momentum as an alternative to meet the ever increasing demands of customers. This has especially been motivated by the existence of applications that make available to ordinary users a host of services that require higher spectral efficiency and data rates. LTE (Long Term Evolution) and LTE Advanced (LTE-A) with ...

OBJECTIVE To perform a construct validation of the List of Threatening Events Questionnaire (LTE-Q), as well as convergence validation by identifying its association with drug use in a sample of the Brazilian population. METHODS This is a secondary analysis of the Second Brazilian National Alcohol and Drugs Survey (II BNADS), which used a cross-cultural adaptation of the LTE-Q in a probabilis...

Energy efficiency (EE) of wireless telecommunications has become a new challenge for the research community, governments and industries in order to reduce CO2 emission and operational costs. EE of base stations (BSs) in cellular networks is a growing concern for cellular operators to not only maintain profitability, but also to reduce the overall negative impact to the environment and economic ...
