ANRITSU CORPORATION is proud to announce verification and support of 3GPP RAN5 Rel-17 NR UDC testcases in collaboration with Qualcomm Technologies using the Qualcomm® X105 5G Modem-RF. This verification was conducted using Anritsu’s 5G NR Mobile Device Test Platform ME7834NR.

Global smartphone usage continues to grow rapidly, driving sustained increases in mobile data traffic alongside rising user expectations for consistent quality of service, regardless of network load or cell conditions. Users now expect always‑on connectivity with reliable performance across a wide range of usage scenarios. One effective approach to improving user experience and network efficiency is data compression.

Uplink transmissions often contain a significant proportion of protocol overhead, including IP and transport-layer headers, while traditional mechanisms such as Robust Header Compression (ROHC) address header compression.

3GPP Release 17 introduces Uplink Data Compression (UDC), enabling further reduction of redundant data prior to transmission. UDC operates at the UE side before radio transmission, improving uplink efficiency by reducing the volume of transmitted data where redundancy exists. This leads to improved spectral efficiency and increased effective user data throughput, particularly for traffic types that are not already compressed or encrypted.

Through this collaboration, Anritsu and Qualcomm Technologies, Inc. are supporting the industry’s validation of UDC conformance and interoperability, helping accelerate commercial implementation of 3GPP Release 17 features.

“Support for 3GPP Release 17 Uplink Data Compression test cases enables more efficient use of uplink radio resources by reducing redundant data prior to transmission,” said Yokoo Daizaburo, General Manager of Mobile Solutions Division at Anritsu. “By enabling accurate verification of UDC functionality, Anritsu supports operators and device vendors in improving effective uplink throughput and overall network efficiency, particularly in scenarios where data compression provides measurable benefits.”

“We are proud that our collaboration with Qualcomm Technologies supports the industry’s implementation and validation of new 5G features such as Release 17 Uplink Data Compression quickly and with confidence,” he added.

The conformance tests are defined by 3GPP in TS 38.523-1 and aligned with the core requirements in TS 38.323. These tests have been submitted by Anritsu to 3GPP’s Radio Access Network Working Group 5 (RAN WG5). They are available on 3GPP RAN5 portal.

Solution Outline 5G NR Mobile Device Test Platform ME7834NR

The 5G NR Mobile Device Test Platform ME7834NR is registered as Test Platform 251 with both the GCF and PTCRB.

This platform supports 3GPP-based Protocol Conformance Test (PCT) and Carrier Acceptance Testing (CAT) of mobile devices incorporating Multiple Radio Access Technologies. It covers 5G NR in both Standalone and Non-Standalone modes, along with LTE, LTE-Advanced, LTE-A Pro, W-CDMA and NTN. When paired with Anritsu’s OTA RF chamber MA8171A and RF converters, the ME7834NR supports testing in sub-6 GHz and millimeter wave (mmWave) 5G NR frequency bands.
