The partners achieved a new milestone by aggregating 800MHz of high-band
spectrum and 60MHz of mid-band spectrum to reach speeds of up to 5.1Gbps on an
individual user device. This is the first time that millimeter wave (mmWave) has
been tested in a 5G Standalone (5G SA) mode combined with mid-band spectrum.
The 5G Dual Connectivity, or New Radio (NR) DC, test was performed in a
millimeter wave (mmWave) chamber, sending the signal over-the-air to a device
with a MediaTek M80 5G modem. The demo used Ericsson Radio System hardware* and
Ericsson’s 5G Core with an IP-flow centric architecture for cost-efficient
support of high peak rates.
The demo successfully showed that mmWave can be used robustly in new 5G SA
architecture as the connection resides in both mmWave and mid-band spectrum.
This will enable higher uplink and downlink data rates for 5G SA than currently
deployed. NR DC supports the evolution of high-performance, latency-sensitive
applications for consumers and enterprises. It will help pave the way for new
innovative use cases for mobile broadband and Fixed Wireless Access (FWA), such
as gaming and immersive media.
Hannes Ekstrom, Head of Product Line 5G RAN, Ericsson, says: “This 5G
technology breakthrough with our partner MediaTek is the direct result of our
efforts to meet the evolving connectivity needs of our customers worldwide. We
believe that New Radio Dual Connectivity will be a very appealing option to many
customers globally as part of their 5G Standalone deployment strategies. It will
enable millimeter wave in the multi-layer network with speeds of over 5Gbps.
Greater capacity and coverage – combined with SA capabilities such as ultra-low
latency – will push the boundaries of 5G technology that will benefit consumers
and industry.”
JS Pan, General Manager of Wireless Communication System and Partnership,
MediaTek, says: “Through this close collaboration with Ericsson, MediaTek has
successfully demonstrated the future-proof capability of its M80 5G modem. NR
Dual Connectivity is one of the latest 5G technology developments that will
directly contribute to next generation 5G services, growing capacity,
performance and enabling innovative new use-cases across business, industry and
consumer ecosystems.”
With NR DC, end users will benefit from higher data rates in both downlink
and uplink. As the throughput is aggregated, this also presents a significant
coverage increase. The advantages of increased speeds and coverage are in
addition to the low latency, improved security, and network slicing capabilities
that 5G SA already enables.
NR DC is enabled by the signaling and high peak rate support in Ericsson’s 5G
Core, 5G radio access network (Ericsson Radio System) and user equipment (UE),
such as the MediaTek M80 modem. Ericsson will release the NR DC functionality
commercially during the third business quarter of 2021.
