scope:

The present document addresses different technical possibilities for local high-quality wireless networks (nomadic or fixed) to access spectrum on a shared basis during a certain time period ranging from short-term (e.g. some days to some weeks) to long-term (e.g. some months to some years).

Also the present document describes high-level use cases, review the feasibility of existing spectrum sharing frameworks, and, if required, propose evolved, extended or new technical solutions for spectrum sharing and network architectures addressing different network topologies and device types.
