Query: Modeling, Simulation and Fairness Analysis of Wi-Fi and Unlicensed LTE
  Coexistence   Coexistence of small-cell LTE and Wi-Fi networks in unlicensed bands at $5$
GHz is a topic of active interest, primarily driven by industry groups
affiliated with the two (cellular and Wi-Fi) segments. A notable alternative to
the 3GPP Rel. 13 defined LTE-Licensed Assisted Access (LTE-LAA) mechanism for
coexistence is the unlicensed LTE (LTE-U) Forum \cite{lteuforum} that
prescribed Carrier Sense Adaptive Transmission (CSAT) whereby LTE utilizes the
unlicensed band as a supplemental downlink unlicensed carrier (to enhance
downlink data rate) to normal operation using licensed spectrum. In this work,
we provide a new analytical model for performance analysis of unlicensed LTE
with fixed duty cycling (LTE-DC) in coexistence with Wi-Fi. Further, the
analytical results are cross-validated with ns-3 (www.nsnam.org) based
simulation results using a newly developed coexistence stack. Thereafter,
notions of {\em fair coexistence} are investigated that can be achieved by
tuning the LTE duty cycle. The results show that as the number of Wi-Fi nodes
increases, the Wi-Fi network in coexistence with LTE-DC with 0.5 duty cycling
achieves a higher throughput than with an identical Wi-Fi network.
