Modeling Transmit Power Reduction for a Typical Cell with Licensed Shared Access Capabilities

Currently, there is a strong demand to augment capacity of mobile cellular deployments as dictated by advanced bandwidth-hungry applications and services. Network densification and the use of millimeter-wave frequencies develop as the mainstream solutions in fifth-generation (5G) mobile systems, but both suffer from increased complexity and cost. A viable alternative is based on the licensed shared access (LSA) framework that manages the spectrum sharing between a limited number of participants. However, interference produced by the current user of the spectrum (the mobile operator) toward its owner (the incumbent) has to be carefully controlled and a number of LSA policies thus emerge. A feasible policy is to reduce the transmit power of the user equipment served by the mobile operator on the LSA bands whenever requested by the incumbent. This paper contributes a mathematical analysis of the said LSA policy in a challenging scenario that features a highly dynamic incumbent (the airport), as well as verifies the findings with more detailed system-level simulations. The obtained results constitute a tight estimate on the practical system operation. © 1967-2012 IEEE.
