The present document studies the architecture, the interfaces and solutions with regards to Licensed Shared Access, LSA ETSI TS 103 154 [5] relevant to a 3GPP mobile network operator. The study includes:

• Study how the solution and architecture defined in ETSI TS 103 235 [3] may provide a global solution.
• Study the impact on the 3GPP management reference model defined in TS 32.101.
• Analyse the LSA functionalities and the information flow defined in ETSI TS 103 235 [3] towards a 3GPP mobile network operator and any impact on Itf-N.
• Study how to support the static and semi-static spectrum sharing scenarios and reference use case defined in ETSI TR 103 113 [4].

Interfaces and functionality specified for LSA that are not involving the 3GPP mobile network operator are out of scope for this study.
