摘要:Spectrum sharing paradigm (SSP) has recently emerged as an attractive solution to provide
capital expenditure (CapEx) and operating expenditure (OpEx) savings and to enhance spectrum
utilization (SU). However, practical issues concerning the implementation of such paradigm are rarely
addressed (e.g., mutual interference, fairness, and mmWave base station density). Therefore, in this
paper, we proposed ultra-reliable and proportionally fair hybrid spectrum sharing access strategy that aims
to address the aforementioned aspects as a function of coverage probability (CP), average rate
distributions (ARD), and the number of mmWave base stations (mBSs). In this strategy, the spectrum is
sliced into three parts (exclusive, semi-pooled, and fully pooled). A typical user that belongs to certain
operator has the right to occupy a part of the spectrum available in the high and low frequencies (28 and
73 GHz) based on an adaptive multi-state mmWave cell selection scheme (AMMC-S) which associates the
user with the tagged mBS that offers a highest SINR to maintain more reliable connection and enrich the
user experience. Numerical results show that significant improvement in terms of ARD, CP, fairness
among operators, and maintain an acceptable level of mBSs density.
