3GPP finalized release 16 in July 2020 enabling the wireless industry to verify compliance to a set of specifications related to 5G new radio (NR) enhancements.

Keysight Technologies, Inc., has collaborated with MediaTek to achieve physical layer interoperability development testing (IODT) based on 3GPP release 16 specifications.

IODT is significant to an ecosystem of device makers developing products for advanced 5G applications. It was achieved using Keysight's PathWave Signal Generation software  and MediaTek's Dimensity 5G-integrated chip platform .

"Joining forces with 5G leaders enables Keysight to help innovators support a wide range of 5G NR applications including enhanced mobile broadband (eMBB), industrial IoT (IIoT), vehicle-to-everything (V2X) and non-terrestrial radio access," said Cao Peng, senior director at Keysight.

PathWave Signal Generation for 5G NR software enabled MediaTek to develop a physical layer algorithm meeting 3GPP Release 16 specifications for its 5G-integrated chips in August 2020. The software, also known as Signal Studio, supports the latest 3GPP 5G NR standards, enabling customers to create waveform files for characterization and testing of transmitters and receivers in base stations and wireless devices.

The 3GPP physical layer IODT milestone is important to the development of 5G NR features such as enhanced multiple-input, multiple-output (eMIMO), beamforming, dynamic spectrum sharing (DSS), carrier aggregation (CA), and positioning.
