Technical Committee (TC) Reconfigurable Radio Systems (RRS) Activity Report 2019

Chair: Markus Mueck, Intel Deutschland GmbH

Responsible for the standardization of Reconfigurable Radio Systems (RRS), including reconfigurable equipment architecture and Cognitive Radio.

The telecommunications industry faces a major challenge – a lack of spectrum to meet growing demand, particularly from the Internet and mobile communications. However, a significant amount of spectrum is allocated exclusively to organizations that do not take full advantage of it.

For example, much is used only across certain areas or at specific times. If this under-used spectrum could be shared, it could free up spectrum resources to support the needs of our connected world, including the Internet of Things (IoT). Sharing will also play a key role in the development of 5G.

Reconfigurable Radio Systems (RRS) – intelligent radio devices which can characterize and act upon their environment – offer an opportunity for the sharing of unused spectrum among multiple services and radio networks. In ETSI our Technical Committee on RRS is responsible for the standardization of these systems, including reconfigurable equipment architecture and Cognitive Radio.

In 2019 the committee published four deliverables.

Within the scope of system aspects and cognitive functionalities, TS 103 655-1 is Part 1 of a multi-part Technical Specification that addresses requirements for the Radio Interface Engine. These embrace KPIs for the acquisition and management of context information, and suitable equipment reconfiguration in a heterogeneous and distributed radio environment which may include satellite, mobile broadband and the IoT.  Work meanwhile progressed on the second part that will define system architecture and fulfil KPIs for efficient acquisition and management of context information, and suitable device configuration in a heterogeneous radio environment.

TS 103 652-1 is Part 1 of a multi-part Technical Specification on evolved Licensed Shared Access (eLSA), covering system requirements for providing spectrum access for local high-quality wireless networks.

We published a Technical Specification TS 103 641 that defines high level system requirements for reconfigurable Radio Equipment (RE) enabling the provision of Radio Applications. We also published revisions to our Technical Report TR 103 585 to define Radio Equipment reconfiguration use cases.

Highlighting the value of ETSI standards, the Radiocommunications Agency Netherlands confirmed in summer 2019 its decision to implement Licensed Shared Access (LSA) technology, based on specifications developed by TC RRS that offer a solution to negotiate spectrum access among multiple services. The Netherlands is now likely to be the first European country to deploy a permanent LSA service based on ETSI specifications in the 2,3 – 2,4 GHz frequency band.
