scope:

The present study addresses technical approaches for automated spectrum access to support dynamic, temporary, and flexible spectrum sharing. Existing spectrum sharing frameworks (e.g. CBRS, LSA, etc.) are evaluated with regard to their suitability for temporary and flexible spectrum access. To evaluate such suitability, the study identifies and assesses properties and parameters (e.g. for scalable localized dedicated networks) that need to be considered. It includes a gap analysis to identify possible for spectrum access for on-demand use cases. This scope includes nomadic deployments.

The applications and use cases described claim a certain, typically high Quality of Service (QoS) but are often limited in range and differ in the duration of operation which can vary from short-term (e.g. some days to some weeks) to long-term (e.g. some weeks to some years). Some use cases allow for prior network planning, others demand very short-term deployment without a prior planning phase.

To support the use cases described, the study evaluates:

• suitability of sharing frameworks for temporary and flexible spectrum access to support ad hoc and on-demand use cases;

• procedures and functionalities for automated spectrum negotiation, assignment, and application specific QoS guarantee;

• suitability for the support of scalable localized dedicated networks;

• suitability for the support of fixed, nomadic, or mobile deployments; and

• characteristics, system architectures and high-level procedures for spectrum access for use cases described

If needed, this study proposes evolution and improvement of the existing technical approaches or develops new technical solutions for spectrum sharing.
