MediaTek and Samsung recently completed what they claimed was the first successful test of a 3Tx five-layer uplink configuration. This collaboration resulted in a total uplink throughput of 670 Mb/s in a joint demonstration.
The test combined MediaTek’s M90 5G modem platform with Samsung’s virtualised RAN (vRAN), Massive-MIMO radios, and Macro radios to set “a new standard in 5G uplink performance”.
The trial integrated three transmit antennas (3Tx) across five uplink layers, using a multi-band setup which combined n66 (1.7GHz) as the primary cell and dual n77 (3.7GHz) carriers.
The configuration represents an extension of earlier three transmit antenna work by using five uplink layers to push spectral efficiency and peak upload speeds beyond previously demonstrated benchmarks.
Samsung’s vRAN provided the network backbone for the trial, with the virtualised architecture allowing flexible resource allocation across multiple frequency bands while serving multiple users simultaneously. Massive-MIMO radios handled advanced antenna processing to manage the parallel data streams with reduced interference.
HC Hwang, GM of wireless communication systems and partnerships at MediaTek, stated the validation marks a significant step for the company’s 5G platform as demand for high-resolution cloud applications continues to grow.
Dongwoo Lee, head of technology solution Group at Samsung Networks, stated the results demonstrate speeds capable of meaningfully improving user experience across both consumer and enterprise applications.
The companies explained the achievement strengthens fixed wireless access performance with improved uplink peak speeds.
The companies did not announce a timeline for commercial deployment.
