Query: Stochastic Geometric Coverage Analysis in mmWave Cellular Networks with
  Realistic Channel and Antenna Radiation Models   Millimeter-wave (mmWave) bands will play an important role in 5G wireless
systems. The system performance can be assessed by using models from stochastic
geometry that cater for the directivity in the desired signal transmissions as
well as the interference, and by calculating the
signal-to-interference-plus-noise ratio (SINR) coverage. Nonetheless, the
correctness of the existing coverage expressions derived through stochastic
geometry may be questioned, as it is not clear whether they capture the impact
of the detailed mmWave channel and antenna features. In this study, we propose
an SINR coverage analysis framework that includes realistic channel model (from
NYU) and antenna element radiation patterns (with isotropic/directional
radiation). We first introduce two parameters, aligned gain and misaligned
gain, associated with the desired signal beam and the interfering signal beam,
respectively. We provide the distributions of the aligned and misaligned gains
through curve fitting of system-simulation results. The distribution of these
gains is used to determine the distribution of the SINR. We compare the
obtained analytical SINR coverage with the corresponding SINR coverage
calculated via system-level simulations. The results show that both aligned and
misaligned gains can be modeled as exponential-logarithmically distributed
random variables with the highest accuracy, and can further be approximated as
exponentially distributed random variables with reasonable accuracy. These
approximations are thus expected to be useful to evaluate the system
performance under ultra-reliable and low-latency communication (URLLC) and
evolved mobile broadband (eMBB) scenarios, respectively.
