Validation achieved at Compliance Agreement Group #77 meeting hosted by Keysight in Malaga, Spain
Santa Rosa, California, January 29, 2024–(BUSINESS WIRE)–Keysight Technologies (NYSE:KEYS) announced the industry’s first 3GPP Release 16 (Rel-16) 5G new radio (NR) single and multiple precoding matrix indicators (PMI) ) got test case approval. 16 and 32 element transmitters operating in frequency division duplex (FDD) and time division duplex (TDD) bands. Validated test cases for use with Keysight’s 5G Network Emulation Conformance Test Platform (TP168) were presented at the Global Certification Forum (GCF) hosted by Keysight in Malaga, Spain in March 2018. Retrieved from Conformity Agreement Group (CAG) #77 meeting. January.
Networks based on the 5G NR standard support multi-antenna technology known as MIMO, which improves spectral efficiency and enhances communications. To implement a multi-antenna system, enhanced precoding techniques are applied at the transmitter to map data to different transmit antennas. The optimal precoding depends on the PMI codebook values reported by the device and is selected from several precoding options based on the device’s own channel measurements.
As part of Rel-16, 3GPP added new test cases to verify device performance in multi-antenna systems. The Keysight S8705A RF/RRM test solution is the first to obtain validation for these new tests, emulating 16 and 32 transmitter connections for use with 2 and 4 receiver equipment (UE). Requires unprecedented fading resources to rate.
Keysight also achieved the following accomplishments supporting enhanced power savings and RedCap features in Release 17 (Rel-17):
-
Test case validation to verify UE support for features that reduce the number of times a device interacts with the network to extend device battery life using the S8705A RF/RRM test solution.
-
Test case validation to ensure RedCap devices support Rel-17 ensures increased Enhanced Discontinuous Receive (eDRX) cycles, which is the time the device goes into sleep mode to extend battery life . This is completed with the Keysight S8704A Protocol Conformance Toolset and activates the RedCap Rel-17 eDRX GCF work item.
Muthu Kumaran, General Manager, Device Acceptance Solutions, Keysight. “For network operators, enhancing connection performance is a top priority to provide better quality of service to end users. NR enables multi-antenna systems and ensures that device performance is thoroughly tested. In order to further advance the advancement of 5G NR Rel-17 towards market introduction of commercial 5G NR and RedCap devices, the first approved tests have been brought to market by Keysight to ensure Validation to support Rel-17 enhanced power saving features is essential. ”
