Energy Detection Based Spectrum Sensing in Wi-Fi and LTE-LAA Co-Existence for 5G System

EasyChair Preprint 7227

Abstract

Presence of both Wi-Fi and small-cell LTE in unlicensed bands (particularly 5GHz), leading to their co-existence is a hot topic for research now a days. For pursuing a friendly co-existence between Wi-Fi and LTE (in unlicensed bands), assimilation of similar back-off and sensing parameters has been done and for this LTE-LAA has been made standardized by 3GPP. To define various protocols in field of telecommunication, various standard developing organizations have been amalgamated to work together under 3GPP. Many research challenges emerge from the co-existence between Wi-Fi and LTE-LAA like honing energy detection threshold, contention window size adjustment, and many others. For a rapid deployment in the field of unlicensed bands, we need a “fair access” as per the 3GPP vital protocols. All we need this time is reliable analytical models to overcome all the challenges emerging from this co-existence. In this work, we have made some amendments in celebrated Bianchi model and with a new make- up we evaluated the throughput for different scenarios of Wi-Fi and LTE-LAA in co-existence as well as without co-existence, by comparing these two we study the effects of various network parameters and right measures to be taken to make this co-existence more friendly. MATLAB software has been used to perform the proper simulations and to get a clear view

Keyphrases: 5GHz unlicensed band coexistence, LTE-LAA (Licensed assisted access), Wi-Fi
