Rohde & Schwarz and Qualcomm have completed the first 3GPP conformance test verification for the Switched Search Space Set (SSSG) power-saving feature for 5G NR. This milestone validates protocol compliance for the feature introduced in 3GPP Release 17 and provides feedback to the RAN5 standardization group to improve future test specifications.
This verification establishes a standardized path for integrating advanced energy-saving features into the 5G mobile ecosystem. By validating the Switched Search Space Set function, manufacturers can now implement power-reduction protocols that extend device battery life while maintaining high-performance connectivity for streaming and data-heavy applications. This development bridges the gap between theoretical 3GPP Release 17 standards and commercial hardware readiness. As the industry moves toward more sustainable hardware, watch for the RAN5 group to adopt the submitted modification requests to finalize global testing specifications for these power-saving mechanisms.
Rohde & Schwarz has built a broad conformance testing portfolio around the CMX500 platform that extends well beyond the SSSG milestone. The company's R&S TS-PCT system, which served as the test bed for this verification, supports protocol conformance testing across multiple 3GPP releases and radio access technologies on a single hardware platform, positioning it as a consolidated solution for device manufacturers navigating the growing complexity of 3GPP Release 17 and beyond. Qualcomm's X105 5G Modem-RF, used as the device under test in this verification, represents the company's current-generation modem platform targeting flagship and premium-tier smartphones, making early conformance validation on this chipset particularly relevant for OEMs planning 2026 and 2027 device launches.

This milestone validates Release 17 protocol compliance, enabling manufacturers to implement energy-saving features that extend device battery life without compromising high-performance connectivity for data-heavy streaming and mobile applications.
They verified the Switched Search Space Set (SSSG) function, which is a power-saving feature defined in 3GPP Release 17.
It optimizes PDCCH monitoring to lower terminal power usage, which helps extend device battery life while maintaining reliable reception of information.
The testing utilized the Qualcomm X105 5G RF modem and the R&S TS-PCT protocol testing platform, with the R&S CMX500 signaling tester serving as the hardware foundation.
The industry expects the 3GPP RAN5 group to adopt submitted modification requests to finalize global testing specifications for these power-saving mechanisms.
