Ericsson and Qualcomm pioneer new carrier aggregation capabilities for 5G
The latest interoperability tests enable communications
service providers to implement new 5G carrier aggregation
capabilities that boost performance, capacity, and
coverage.
Ericsson and Qualcomm Technologies, Inc. have completed
pioneering interoperability tests for 5G standalone (SA)
carrier aggregation across both FDD/TDD* and TDD/TDD
bands. 5G carrier aggregation allows operators to use
multiple sub-6 GHz spectrum channels simultaneously to
transfer data between base stations and a 5G mobile device.
Implementation of 5G carrier aggregation delivers
enhanced network capacity along with improved 5G speeds
and reliability in challenging wireless conditions, allowing
consumers to experience smoother video streaming and
enjoy faster downloads. This key 5G capability is expected
to be widely deployed by operators around the world in 2021.
The partners completed a 5G SA carrier aggregation test at
Ericsson’s labs in Beijing, China. The connection reached
2.5 Gbps peak speeds by aggregating
100 MHz + 60 MHz within the 2.5 GHz (n41) TDD band in a
70 percent downlink configuration and using 4×4 MIMO.
In addition, in Sweden, the two companies established a
successful 5G SA carrier aggregation data call by combining
20 MHz in the 600 MHz (n71) FDD band with 100 MHz of
spectrum in the 2.5 GHz (n41) TDD band.
Both achievements used 5G infrastructure equipment from
the Ericsson Radio System portfolio and a 5G smartphone
form factor test device powered by a Qualcomm®
Snapdragon™ X60 5G Modem-RF System.
Durga Malladi, senior vice president and general manager,
4G/5G, Qualcomm Technologies, Inc., says: “As the world’s
leading wireless innovator, Qualcomm Technologies
continuously develops solutions that will help the fast
proliferation of 5G globally. We’re proud to collaborate with
Ericsson on this 5G carrier aggregation milestone –the
world’s first featuring both FDD/TDD and TDD/TDD
aggregation– as this technology significantly enhances the
performance of 5G networks worldwide, unlocking even
higher average speeds and better 5G coverage for consumers.”
Per Narvinger, Head of Product Area Networks, Ericsson,
says: “We are pleased to be a lead innovator of 5G carrier
aggregation with Qualcomm Technologies as 5G scales
from initial deployments in cities to wider area coverage.
5G carrier aggregation will be a key technology for
extending the coverage of mid-band and high-band 5G in
addition to enabling faster data speeds and enhanced
performance. We expect to see the first deployments of 5G
Carrier Aggregation in late 2020 with a ramp up in 2021.”
Ericsson will offer a commercial release of 5G NR carrier
aggregation in the fourth quarter this year.
