WInnForum Approves Specifications Focused on CBRS Feature Conformance Testing
Thursday, December 03, 2020 | Comments

The Wireless Innovation Forum (WInnForum) approved an updated Citizens Broadband Radio Service (CBRS) operational and functional requirements document — WINNF-TS-1001 Version 1.2 — that, along with five other specifications, provide self-testing conformance information for multiple CBRS enhanced (Release 2) features.

In addition, spectrum access system (SAS) operators and CBRS device (CBSDs) providers will be able to indicate the features they support publicly on the forum’s website.

“Ericsson applauds the publication of the WInnForum enhanced features (Release 2) technical specifications that support devices with a wide range of capabilities while ensuring backward compatibility with baseline standards (Release 1) certified devices,” said Paul Challoner, vice president of network product solutions, Ericsson North America. “The new standard introduces a flexible framework that allows each equipment provider to prioritize the introduction of the features which are important to their customers.”

Enhanced (Release 2) specifications include updates to the SAS to SAS and SAS to CBSD protocols to support new features, and a resulting test specification that allows industry to self certify against requirements that do not impact Part 96. To address backward compatibility with the WInnForum baseline (Release 1) standards, the only mandatory feature for a SAS operator or CBSD is to support the feature capability exchange between SASs and CBSDs.

The entire package of specifications enabling this exciting development in CBRS includes:
• WINNF-TS-1001 CBRS Release 2 Operational and Functional Requirements
• WINNF-TS-3002 Extensions to SAS-CBSD Interface Technical Specification (Release 2)
• WINNF-TS-3003 Extensions to SAS-SAS Interface Technical Specification (Release 2)
• WINNF-TS-4003 CBRS Release 2 NRI Test Specification for SAS as UUT
• WINNF-TS-4004 CBRS Release 2 Test Specification CBSD DP as UUT
• WINNF-TS-4005 CBRS Release 2 Self-Testing Policy

Enhanced features supported include enhanced CBSD group handling, principal-subordinate single frequency group, interdependent single-frequency group, separable single-frequency group, enhanced antenna patterns, customer premises equipment (CPE)-CBSD indicator and passive distributed antenna system (DAS).

Additional emerging technologies can be considered in subsequent releases, the forum said. Development is already underway on further features considered for addition to Release 2 including flexible grants and grant updates, indoor penetration loss measurements, refined propagation modeling, registration enhancements and support for beamforming.
