Analytical Evaluation and Potentials of Frame Based Equipment for LTELAAWiFi Coexistence Telecommunication agencies are facing the problem of spectrum scarcity with respect to the dramatic increase of demand of new spectrum to support 5G network services. The inefficient usage of the limited spectrum necessitates the coexistence of different radio access technologies in the same spectrum. Sharing the spectrum without negative impact is a prerequisite for telecommunication agencies before allowing new radio access technology to coexist with incumbent technology already using the spectrum. In this work, we develop general analytical models to evaluate the potentials of the Frame Based Equipment (FBE) MAC protocol that can be used by LTELAA networks to share the spectrum with WiFi. We derive the expressions of the performance of both networks and we validate them by NS3 simulations. We show that FBE can be a good tradeoff that offers an acceptable LTELAA performance while reducing the negative impact on WiFi if both network parameters are well tuned. In particular, increasing the WiFi data rate, increases the performance of LTELAA and the overall performance.

To Analysis Performance Measures of 3GPP Wireless Network within LAA Framework Over the past few years, the number of mobile network users and the range of offered to them services has increased dramatically. This has led to a significant increase in generated in mobile network traffic volume, the transmission of which requires not only high network bandwidth but also the ability of operators to provide users services with the required quality of service (QoS) level. In such conditions, there is the problem of frequency spectrum lack, which requires operators and standardization organizations to search for an effective solution. There are two types of these problem solutions: attracting additional resources, for example, using higher frequencies, such as mmWave, or more efficient use of existing ones, for example, through the use of Licensed Shared Access (LSA) or Licensed Assisted Access (LAA) frameworks. We focus on LAA framework that was introduced by the 3GPP consortium as part of LTE Advanced (LTEA) technology and defined as a system capable of ensuring the coexistence of LTE and WiFi networks in unlicensed bands. In this paper, we propose two radio admission control schemes to the shared spectrum of 3GPP wireless networks within LAA framework. Services provided to users generate elastic traffic with minimum requirements to QoS level (GB services).
