Anritsu Corporation has completed verification of 5G NR (New Radio) Rel-17-based uplink data compression technology in collaboration with Qualcomm. This technology improves data transmission efficiency and suggests the potential for performance improvement in 5G Standalone (SA) environments.

Anritsu announced on the 22nd that it has completed 3GPP RAN5 Rel-17 NR UDC (Uplink Data Compression) test case verification for devices equipped with the Qualcomm X105 5G Modem-RF in collaboration with Qualcomm Technologies. The 5G NR mobile device test platform 'ME7834NR' was used for the verification.

UDC is a feature defined in 3GPP Release 17, a technology that reduces the amount of data transmitted by compressing data at the terminal side before wireless transmission.

Uplink data has a high proportion of overhead consisting of IP and transport layer headers, etc. Previously, ROHC (Robust Header Compression) handled this, but UDC is a method that improves transmission efficiency by additionally removing redundant data.

The company explained that applying this technology enables improvements in spectrum efficiency, uplink data transmission efficiency, and user-perceived speed.

This verification was performed based on the 3GPP TS 38.523-1 and TS 38.323 specifications. The relevant test cases were submitted to 3GPP RAN WG5.

ME7834NR is a test instrument that supports various communication standards, including 5G NR standalone and non-standalone operation, as well as LTE, LTE-A Pro, W-CDMA, and NTN. It also supports sub-6GHz and millimeter wave (mmWave) band test environments.

Anritsu announced that through this collaboration, it supported the commercialization verification of Rel-17-based data compression functions.

A company official explained that the technology can be utilized for stable data transmission and efficiency improvement even under heavy network load.
