Abstract
Regulatory authorities globally are looking for new
policy making solutions to achieve more efficient
spectrum usage by allowing multiple systems to share the
same spectrum bands with the aid of cognitive techniques.
This quest has led to the development of different
spectrum sharing solutions in different parts of the
world for optimising spectrum use in various spectrum
bands. Despite the active widespread research on spectrum
sharing over nearly two decades, only a few solutions
have attracted the interest of industry and regulators as
potential concepts for adoption. Though the selected
solutions offer great promise, none have proven
commercially successful at the time of the writing of
this document. The process to introduce and adopt a new
sharing concept in a specific spectrum band is very
complex and the manner in which this introduction can
take place varies considerably based on the regulation
structure and the cultural norms of the nation where the
deployment takes place. However, some general principles
can be found and established for the process. Knowledge
of these principles will allow researchers to develop
their approaches taking into account requirements arising
from different stakeholders in various phases of this
process. In this paper, the spectrum sharing ecosystem
and three prominent and most recent regulatory spectrum
sharing concepts from Europe and US are introduced. Based
on an analysis of these concepts, a general process model
for spectrum sharing is introduced covering the roles and
tasks of different stakeholders and emphasizing the need
for seamless cooperation and interactions between them at
different phases of the process. The general process
model that is presented here can serve as a guideline for
the development of new spectrum sharing models and help
regulatory authorities to optimize the existing processes
by pinpointing tasks for each stakeholder as providing a
guide for the critical information that is needed for
each phase of the process. Moreover, for academic and
industry research and especially those involved with
entrepreneurial endeavours, the paper gives a useful
overview of the complicated administrative process behind
and factors that contribute to the regulatory acceptance
of a sharing concept.
