The main objectives of the study are to :
- Investigate the benefits of new, forward looking dynamic spectrum access techniques, over currently existing methods to share spectrum among services
- Study the feasibility, performances and benefits of those promising techniques over relevant SATCOM scenarios
- Formulate a strategy to enable the use of dynamic spectrum access techniques, also taking into account the necessary evolutions of the current regulatory framework
The major outcomes are to :
- Establish a roadmap of the key technologies needed to be developed to make such techniques viable,
- Identify the actions at regulatory or standardization level that shall be followed by the Agency to enable such framework
The benefit of this study is to optimize the spectrum utilization in order to ensure the future cohabitation between the terrestrial and satellite services.
Several System architecture are addressed in order to study the different scenarios.
The overall work logic is presented in the following figure:
During the WP100, 5 scenarios of dynamic spectrum sharing involving SATCOM are described and the spectrum sharing techniques are analysed. A number of Key Performance Indicators is established to evaluate all the use cases and select 2 among them. A detailed design of the selected spectrum sharing techniques is realized in the WP200. The performances of the designed spectrum sharing techniques are assessed in the WP300. The recommendations for future developments are carried out in the WP400.
The first progress meeting took place in May. The TN 1 was released. It contains the description of 5 scenarios of dynamic spectrum sharing. 2 scenarios are selected. Work on WP 200 and 300 is in progress.
