3. Scope of SCC41
This Standards Coordinating Committee will develop standards related to dynamic spectrum access networks.
The focus is on improved use of spectrum.
New techniques and methods of dynamic spectrum access require
managing interference,
coordination of wireless technologies and
include network management and information sharing.

6. 1900.4
Defines management system to support network-terminal distributed optimization of radio resource usage and improvement in QoS in heterogeneous wireless networks
In particular, the draft standard defines
system and functional requirements
system and functional architecture
information model
generic procedures
An informative part of the draft standard describes
use cases
deployment examples

7. Some Use Cases Dynamic spectrum assignment,
where the available spectrum is dynamically assigned to the participating RANs depending on their requirements.
Dynamic spectrum sharing,
where the available bandwidth assignment is fixed but several RANs can share the same spectrum band. This is the use case enclosing the White Spaces scenario.
Distributed radio resource optimization,
where the network configures the terminals to improve spectrum usage and quality of service.

8. Need For Project
The IEEE is the baseline standard defining architectural building blocks enabling network-device distributed decision making for optimized radio resource usage in heterogeneous wireless networks.
To ensure interoperability between network side and terminal side components of the IEEE system, detailed description of interfaces and service access points defined in the IEEE standard is required.

10. 1900.6
This standard defines the information exchange between spectrum sensors and their clients in radiocommunication systems.
They define following modules:
Sensor (S)
Data Archive (DA)
Cognitive Engine (CE) that communicate with each other and with external services
Users utilizing distinct service access points (SAPs),
Application SAP (A-SAP),
Communication SAP (C-SAP)
Measurement SAP (M-SAP).
