Assessment of channel interference for Licensed Shared Access (LSA) in the 2.3-2.4 GHz band

Rapid technology development in mobile devices and network technologies has caused an explosive growing in mobile traffic demand leading to the need for more market driven approaches for spectrum access. European spectrum regulation administrations have started to consider the development of strategic approaches and policies for spectrum sharing under the Licensed Shared Access (LSA) framework. In Europe the 2.3-2.4 GHz band has been identified as the first potential application area for sharing between a mobile network operator and the incumbent spectrum users under LSA framework corresponding to the new Authorized Shared Access (ASA) concept. This paper evaluates the suitability of the 2.3-2.4 GHz band for sharing between incumbent spectrum users and mobile network operators as the entrants under the new LSA/ASA framework. In particular, an analysis of the spectrum usability for sharing is presented considering realistic systems for sharing. Simulations are conducted to assess the sharing conditions between incumbent programme making and special events (PMSE) services and entrant LTE network. Results suggest that sharing in this band requires good coordination for LSA/ASA.
