Trinity College Dublin

<p><strong>Overview:</strong> As Ireland’s university on the world stage, Trinity is recognised for academic excellence and a transformative student experience. The historic campus is located in the heart of Dublin city centre at the meeting place of the retail and cultural districts. With a tradition of scholarship spanning more than four centuries, Trinity is home to talented and inquiring minds, a liberal education, and research conducted at the frontiers of disciplines.</p>
<p><strong>Research:</strong> Trinity’s position as one of the world’s leading universities is defined by our research, scholarship, and capacity to address issues of global, societal and economic importance. Our strength lies in the breadth and excellence of our expertise; from individual-scholars and thought-leaders, to large multidisciplinary teams, each delivering research of national and global importance.</p>
<p>Trinity’s research themes address issues of immediate and long-term concern for society and offer opportunities for future economic development. They are supported by a set of research institutes that provide the infrastructure that is required to support multi-disciplinary research as well as partner engagement.</p>
<p><strong>Industry Partnerships:</strong> Trinity is committed to supporting industry — from SMEs to MNCs, from short term projects to long term on-going collaborative projects. In a national or international context, we work collaboratively with industry stakeholders and agencies to share infrastructure and expertise, tackle industry relevant research challenges, problems, or address grand challenges.</p>


<h1 id="technology-overview">Technology Overview</h1>
<p>Demand for LTE bandwidth is increasing and frequency bands are becoming more congested. The problem is addressed by enabling spectrum sharing and increasing spectrum efficiency through better spectrum management. This system enables a cellular operator to compute bandwidth from shared spectrum in a cellular network. It provides a mechanism for calculating the required spectrum resources a cellular operator needs to lease from a shared spectrum class to provide a minimum QoS to an end-user. As an input, the mechanism uses QoS metric based on the downlink rate of an average user. The objective is to determine the minimum spectrum requirement from the exclusively shared spectrum class to meet the average user target rate. The user rate is obtained by computing</p>
<ol>
<li>its SINR</li>
<li>the normalised throughput</li>
<li>the average amount of spectrum resources the user gets for each spectrum class. </li>
</ol>
<p>Furthermore, a design parameter (access probability threshold: based on the percentage of users able to connect to the commonly shared channel), determines whether the throughput from this spectrum class should be taken as an input into the decision-making process.

<p>Stage of Development:</p>
<p>Deployed on testbed.</p>
<h1 id="benefits">Benefits</h1>
<p>This technology ensures balancing of QoS and cost through a spectrum selection mechanism, which minimises cost (of the spectrum), while at the same time provides the required QoS, quantified as average user throughput. </p>
<p>It provides flexibility and scope in how the future, potential sharing bands (below and above 6 GHz) can be incorporated and mapped to the two spectrum classes (where one is free and one is fee paying).</p>
<p>By adopting the selection mechanism, an operator would see an average reduction of 30% in the fee-paying exclusively shared spectrum that it would need to access.</p>
<h1 id="applications">Applications</h1>
<p>The invention could be deployed in a radio access network, controlling the allocation of different spectrum classes to a group of base stations, or it can be incorporated into an OSS system, performing the same task.</p>
