This SpringerBrief investigates cross layer resource allocation in
unlicensed LTE (Long Term Evolution) HetNets. Specifically, the authors
study and cover the radio access management of unlicensed LTE to allow
efficient spectrum utilization and harmonious coexistence with other
unlicensed systems in this brief. Efficient radio access protocols are
developed to allow unlicensed LTE users to fair share channel access
with unlicensed users in different systems, including Wi-Fi and
unlicensed LTE of other operators. An analytical model is developed to
study the performance of the proposed protocols.
To achieve efficient spectrum sharing among various unlicensed users,
the authors further formulate a resource allocation problem based on
Nobel Prize winning game theory framework, and propose efficient
algorithms to achieve the maximal user utility. Opportunistic traffic
offloading from licensed band to unlicensed bands is also investigated,
based on the network formation game. By exploiting the characteristics
of mobile social networks, the offloading performance can be further
enhanced.
This brief targets researchers and engineers from both academia and
industry interested in the development of LTE over unlicensed bands, as
well as the design and implementation of cross layer radio resource
management. Students studying electrical engineering and computer
science will also find this brief useful for their studies.
