Ericsson demos 5G Dynamic Radio Resource Partitioning

Ericsson demonstrated Dynamic Radio Resource Partitioning, a 5G Radio Access Network (RAN) Slicing solution that will enable six mobile network operators (MNOs) to deliver customized 5G services with guaranteed performance.

Each MNO sharing DNB’s network has access to the full spectrum asset to achieve the best possible speed, while simultaneously ensuring the pooled spectrum is efficiently used and maximized among all other MNOs. The Ericsson solution optimally provisions each MNO in order to ensure a good end-user experience. This allows each MNO to offer services that meet the Service Level Agreements (SLA) and provides guaranteed resources as configured.

Dynamic Radio Resource Partitioning is one of the features of Ericsson 5G RAN Slicing, a software solution that dynamically allocates spectrum resources at millisecond scheduling and supports multi-dimensional service differentiation handling across slices. In short, RAN Slicing optimizes radio resources, strengthening end-to-end slicing capabilities for dynamic resource management and orchestration. This ensures fast and efficient delivery of services as well as high-quality user experience required by diverse use cases.

Malaysia’s Digital Nasional Berhad (DNB) will be the first commercial network in the world to deploy the solution.

David Hägerbro, Head of Ericsson Malaysia, Sri Lanka and Bangladesh, says, “Ericsson’s first-in-the-world application of our Dynamic Radio Resource Partitioning technology catering for six MNOs on one 5G network is an example of our commitment to providing a world-class 5G network to Malaysia. This technology solution enables all six MNOs to deliver customized 5G services with guaranteed performance. This innovation also allows each MNO to differentiate its offering to consumers on the shared 5G network.”


EVG and Teramount target wafer-level silicon photonics packaging

Nokia and AT&T target 5G uplink with distributed massive MIMO

AT&T is working with Nokia Bell Labs in testing distributed massive MIMO (DmMIMO) to significantly increases uplink capacity and speeds in 5G networks without requiring an overly complex solution. Specifically, Nokia is collaborating with AT&T on the validation of DmMIMO and testing the proof-of-concept technology in the AT&T labs. Bell Labs’s DmMIMO simulations have demonstrated increases in 5G uplink capacity between 60% and 90% compared to similarly configured systems with a single panel. While other techniques come at the expense of downlink capacity, DmMIMO would produce sizable increases in uplink capacity without sacrificing performance.

DmMIMO allows devices to leverage signal propagation to multiple cells or antenna panels in a network when establishing a link, thereby turning noise into a useful signal and increasing the uplink throughput. The data transmission is pieced together from multiple antenna panels and cell sites through distributed baseband processing. The processing load between the cell site radio units and the central processing unit is split in a novel way, reducing the fronthaul capacity to cell sites and hence lowering the cost.

Nishant Batra, Chief Strategy and Technology Officer, Nokia, said: “Addressing uplink speeds is becoming critical as consumers are increasingly becoming content creators as well as content consumers, video conferencing has become a cornerstone of the teleworking era, and many of the applications in the industrial internet of things require higher uplink speeds. When 5G-Advanced networks come online, we will see the network enhanced in multiple dimensions, expanding and extending its capabilities. Even today, with the focus on 5G mid-band spectrum rollouts in the U.S., there are opportunities for technologies like this that can maximize available resources. We feel distributed massive MIMO will be a critical element of networking in the 5G-Advanced era to help meet these demands with significant gains in uplink without a hit to downlink performance. Three decades ago, Bell Labs and AT&T invented MIMO, so it is only fitting that we continue this groundbreaking work together for the next generation of MIMO.”

Andre Fuetsch, Executive Vice President & CTO Network Services, AT&T, said: “AT&T and Nokia have a long history of working together on new network technologies, and I welcome this strategic collaboration for the development of distributed massive MIMO technology. Newer applications in the 5G-Advanced timeframe, such as eXtended Reality (XR), are expected to be more demanding on the uplink compared to regular broadband traffic. Technologies such as distributed massive MIMO show potential to improve uplink capacity in the right scenarios. DmMIMO is also a technology that shows potential for the next generation of wireless networks. Therefore, this strategic technology collaboration with Nokia may help provide learnings with long-term benefits to both companies.”

FCC seeks comment on BGP vulnerabilities

The FCC is seeking public comment on any steps that the Commission should consider taking to help protect and strengthen the nation’s communications network and other critical infrastructure from vulnerabilities posed by BGP.

The FCC observes that a bad network actor may deliberately falsify BGP reachability information to redirect traffic to itself or through a specific third-party network, and prevent that traffic from reaching its intended recipient. The FCC says Russian network operators have been suspected of exploiting BGP’s vulnerability to hijacking, including instances in which traffic has been redirected through Russia without explanation.

Specifically, the FCC is seeking comment on the extent to which Internet Service Providers, public Internet Exchange Providers, and providers of interconnected VoIP service have deployed BGP routers in their networks.  Do content delivery networks, and providers of cloud services operate BGP routers in their networks as well?  What other types of entities operate BGP routers?
