Modeling the utilization of a multi-tenant band in 3GPP LTE system with Licensed Shared Access

Abstract

Fueled by the rapid growth of mobile services, the actual demand for efficient sharing of available but underutilized frequency spectrum puts pressure on the responsible players (ITU, ETSI) to rethink the feasible ways of allocating wireless spectrum. Today, the LSA regulatory framework is considered to be an important enabler for optimized spectrum sharing between the incumbent and the LSA licensee (e.g., mobile network operator). At any point of time, the frequency bands can be utilized by only a single party, and the spectrum owner has priority in its usage at all times. In this paper, we introduce a mathematical and a system model for the multi-tenant band within the 3GPP LTE cellular network. As the main output of this work, the obtained numerical results for one multi-tenant band are produced. Said band is assumed to be intolerant to traffic delay and our results include the blocking probability as well as the mean downlink TX power of the eNodeB.
