  3. 310/06/2014 3 Introduction  Mobile traffic is growing at rapid pace leading to increasing spectrum demand.  New frequency sharing concepts are being developed to access new already licensed spectrum bands on a shared basis. Europe: Licensed Shared Access (LSA) concept is under heavy study in regulation and standardisation for MNOs in 2.3GHz.  This paper presents a live demonstration of the LSA concept implemented using commercial mobile network elements (LTE base stations, core network, management system).

  5. 510/06/2014 5 LSA Concept  LSA concept aims at allowing new licensed users on spectrum bands that already encompass incumbent spectrum users with spectrum sharing that provides a certain quality of service for both the entrants and the incumbents.  Incumbent defines the part of the spectrum, license duration and area that is available.  License sharing agreement is set between incumbent and LSA Licensee. Spectrum regulator issues the license to LSA Licensee.  Incumbent can reclaim the spectrum back on demand for own business -> “dynamic” behavior  LSA concept targets an interference free operation for both. For MNOs, the LSA might be an opportunity to access 2.3GHz band, which is not totally used by other type of incumbents.

  14. 14 Conclusions
  15. 1510/06/2014 15 Conclusions  Live trial of the LSA concept where a TD-LTE live network shares the spectrum in 2.3-2.4 GHz band with incumbent PMSE service.  Dynamic availability of the LSA band can be handled with existing network equipment, mainly network management system, and a minimum number of additional components, LSA Repository and LSA Controller.  Future work will include small cells, more dynamic traffic steering/load balansing, and interference measurements.
