en.Wedoany.com Reported - MediaTek and Samsung recently achieved a total uplink throughput of 670 Mbps in a 5G uplink technology demonstration, combining three transmit antennas with multi-band carrier aggregation.
The demonstration utilized MediaTek's M90 5G modem platform and Samsung's virtualized RAN (vRAN), massive MIMO radio (MMU), and macro base station radio technologies. In terms of specific configuration, the demo integrated three transmit antennas (3Tx), using the n66 band (1.7GHz) as the primary cell, and combined dual n77 band (3.7GHz) carriers, forming a total of five uplink layers. The n66 band operated with a 30 MHz bandwidth, while the n77 bands used a combined 200 MHz bandwidth, together achieving a total uplink throughput of 670 Mbps. MediaTek claimed that this result enhances fixed wireless access (FWA) performance, significantly improving uplink peak rates. The project also involved optimizing resource allocation, managing multiple frequency bands while simultaneously serving multiple users, with MMU technology improving spectral efficiency across multiple data streams. The two companies stated that the demonstration validated significant spectral efficiency and transmission improvements, which will bring more reliable experiences for data-intensive activities.
Dr. HC Hwang, General Manager of MediaTek's Wireless Communication Systems and Partnerships, said: "The successful verification with Samsung is a transformative milestone for MediaTek's 5G platform. As demand for ultra-high-definition cloud applications continues to surge, this technology will be a key driver for next-generation industry innovation." Dongwoo Lee, Head of the Technology Solutions Group at Samsung Electronics' Network Business, added: "By collaborating with MediaTek to achieve another industry-first milestone, Samsung continues to lead uplink performance improvements through advanced configurations. This joint test demonstrates exceptional speed, translating into an unparalleled user experience and reliable, continuous connectivity. These advancements have the potential to revolutionize industry and consumer usage."
Last month, Ericsson and KDDI completed a large-scale AI-driven uplink optimization field trial on a commercial network in Japan. The trial covered a multi-technology, multi-band cluster comprising approximately 1,500 5G cells and 1,300 4G cells, verifying that AI-based uplink interference management can achieve scalable improvements under real traffic conditions. Trial results showed that 4G throughput gains improved by an average of 9.6%, and 5G by 3.1%; meanwhile, the 5G signal-to-interference-plus-noise ratio (SINR) improved by 27%, and both 4G and 5G uplink modulation efficiency and spectral efficiency were enhanced.
