Regulation, standardization, business
Contributions to CEPT on LSA concept (ECC Report 205) and ITU-R on cognitive radio systems in the land mobile service with chairmanship.
Business studies on LSA work flow and tasks of key stakeholders, business models for MNOs, scenarios for incumbents and benefits for key stakeholders.
Technical research on LTE SON and LSA architecture.
Finland (Finnish Trial program) as the single most contributing country at COST Action IC0905 TERRA 2010-2014.
Lesson 1: The Power of Collaboration
Trial program introduced a new way of doing research in a collaborative way
Required a big change in attitude which was not always easy
Project internal between organizations (research, industry, regulation)
Between Trial program projects
Collaboration turned out to be the key for achieving big results
Concrete example: Joint LSA trials
Collaboration should continue to share information and avoid overlapping and duplication of work
Lesson 2: Holistic view covering interrelations of technology, research and regulation
Regulation (CEPT, ITU-R)
Standardization (ETSI, 3GPP)
All interrelated and on the same topic.
Lesson 3: Agile/Lean/Iterative methods for trial development
Consecutive public LSA trial demonstrations with new features (several per year)
Force you to work efficiently by selecting and developing the most important features first, integrate and test continuously with others
Opportunity to collect feedback from stakeholders
Essential in the development of new concepts whose features are unknown in the beginning of the project
Opportunity to take into account technical/business/regulation developments in the trials
Lesson 4: Publicity
LSA concept brought to the attention of the whole world
Public trials in Europe, US and Asia (?) to promote the LSA concept and Finland’s cutting edge position in spectrum sharing
Presentations to all involved stakeholders in different forums with clear and simple messages to collect feedback
Regulation (regulatory forum workshops), research (academic conferences), and industry
Active publication work coupled with trials to get publicity
Trials and papers in same events
Other related activities – European LSA development
LSA concept development in Europe continues in ETSI and CEPT
Only 2.3-2.4 GHz band considered so far
Current mandate on geolocation database
Upcoming mandate on the 2.3-2.4 GHz band for wireless broadband with LSA (if needed) in 2015
On-going work on RSPG report “Efficient awards and use of spectrum bands harmonised for Electronic Communications Services” (best practices on spectrum award approaches and related conditions, including spectrum sharing and/or pooling with a view to achieve higher transmission speeds and capacity in 2015)
Identification of beneficial sharing opportunities (BSOs)
ETSI timeline for LSA
TS 103 235: System architecture for LSA, target Nov 2014
TS 103 154: System requirements for LSA in 2300- 2400 MHz, target Aug 2014
Interface definitions expected to start in 2015
TR 103 113: SRdoc Mobile broadband services in the 2300 – 2400 MHz band under LSA
Other related activities
US spectrum sharing developments
Three-tier hierarchy model under study in 3.55-3.65 GHz band
ITU-R work on spectrum sharing
ITU-R WP5A will finalize its work on CRS in 2014 giving the general guidelines for spectrum sharing
ITU-R WP1B work on “dynamic access” is on-going and could expand in the future
Current sharing models (LSA and US model) are only for the first band – and not yet implemented even there
There is a need to continue the spectrum sharing studies and trials
Future trial topics
New interfaces in LSA
Larger LSA LTE network
Different types of incumbents
Small cells and clusters of small cells
LSA with Active Antenna Systems (AAS)
Load balancing and traffic steering
Power of collaboration
Trial program introduced a new way of doing research in a collaborative way => This has led to results with big impact.
Holistic view covering interrelations of technology, research and regulation
Looking at the concept from different angles improves the quality.
Agile/Lean/Iterative methods for trial development
Consecutive public trials increase the quality by getting feedback.
Spectrum sharing still requires further research and trials
Current models (LSA and (US model) are being studied for single band and not yet implemented even there.
