Qualcomm Technologies, Inc., in collaboration with Samsung Electronics Co., Ltd., announced that the companies have executed the simultaneous 5G 2x uplink and 4x downlink carrier aggregation (CA) for FDD (frequency division duplex) spectrum. This achievement underscores the companies’ joint management in paving way for future of 5G performance and flexibility.

BT and Ericsson have demonstrated the transmission of 5G services in a wideband FDD (frequency division duplex) radio carrier (over 20MHz) within a sub-3 GHz spectrum band. The trial demonstrated benefits of configuring a carrier bandwidth of 50MHz (50MHz downlink + 50MHz uplink) in EE’s 2.6GHz band and performing downlink aggregation with two TDD (time division duplex) carriers in EE’s 3.5GHz band. The trial also evaluated an intermediate carrier bandwidth of 30MHz.

Blue Danube Systems, a provider of intelligent wireless access solutions that help mobile operators address the challenge of explosive data growth, announced it has successfully expanded the commercial deployment of its massive MIMO solution to multiple clustered cell sites, demonstrating total capacity improvements for directly adjoining sectors on existing LTE networks using current smartphones. “Blue Danube Systems to demonstrate benefits of FDD massive MIMO in clustered multi-sector deployments”

Nokia has announced that they have completed interoperability testing with a Mavenir radio using the O-RAN Alliance 7-2x interface at Nokia’s Open RAN Innovation Centre in Dallas, Texas. “Nokia and Mavenir validate interoperability in Open RAN trial “

ZTE has partnered with China Mobile’s Jiangsu Branch to pilot one of the industry’s first 5G zero-carbon remote radio units (RRUs). The technology can be used to quickly respond to user demands, activating within approximately one minute when needed. This responsiveness improves the user experience and service quality. “Companies collaborate for 5G zero-carbon RRU pilot”

Ericsson has carried out tests on Malaysia’s 5G network deployed by Digital Nasional Berhad (DNB) for the first implementation and validation in Southeast Asia of Ericsson’s pre-commercial Reduced Capability (RedCap) software. The tests were carried out in collaboration with MediaTek, a semiconductor company that designs and manufactures system-on-chip (SoC) solutions, using its 5G RedCap test platform in Malaysia. “Malaysia’s DNB 5G network will be first in region use Ericsson’s 5G RedCap”

Ericsson and Danish digital infrastructure provider TDC NET have switched on the 5G standalone (5G SA) network in Denmark. The transition to high-performance 5G SA technology will enhance the regional 5G ecosystem, accelerate improvement across industries, and unlock exciting possibilities for consumers. This milestone signifies a monumental leap forward in connectivity, enabling advancements and placing Denmark at the forefront of technological progress.

Verizon, Ericsson, and MediaTek have completed data and VoNR (voice over new radio) sessions over Verizon’s 5G network using Ericsson’s new RedCap compatible software NR (new radio) light functionality and MediaTek’s RedCap testing platform. This new technology provides a path for lower-complexity and lower-cost NR devices such as consumer wearables, fitness trackers and mobile medical devices. It also paves the way for enterprise IoT (internet of things) solutions like video surveillance, industrial sensors, and smart grids to run on Verizon’s 5G network. 

BT and Nokia have announced uplink aggregation of two carrier components in a 5G standalone (SA) live network spectrum. Demand for faster uplink speeds is growing in importance for a number of both existing and emerging use-cases, including live-streaming and video calls. Carrier aggregation is an important technique for ensuring high performance as demand and data usage continue to increase. Further benefits include maximisation of spectrum assets and energy efficiency.
