The wake-up signal was first introduced in 3GPP Release 15
In 3GPP Release 15, a paging signal sent over the physical downlink shared channel (PDSCH) that “wakes up” a user device from an idle state so that can prepare to receive data was first introduced....
Service function chaining helps automate traffic flow between services in a virtual network
In order for operators to traffic steer using a sequence of multiple Network Function Virtualizations (NFVs), they must make use of a technique called service function chaining (SFC) or network service chaining, which...
With 5G deployments well underway around the world and the technology beginning the shift from its first, Non Standalone iteration to end-to-end 5G, the focus of standards work continues to look ahead to enhancements yet to be achieved in this generation, while researchers and...
The MDT solution taps user equipment (UE) to collect field measurements
Introduced in 3GPP Rel-10, Minimization of Drive Test (MDT) is a standardized mechanism designed to enable operators to use user devices in a network to collect mobile network data, and thus, reduce the need...
Carriers face a number of operational challenges as 5G continues to evolve and mature, both in terms of deploying and running new 5G networks as well as in managing the relationship of those new networks to existing 4G networks. In a Test and Measurement...
ENDC has been described as a bridge between 4G LTE and 5G cellular technologies
ENDC, or E-UTRAN New Radio - Dual Connectivity, is a Non-Standalone (NSA) feature that makes it possible for mobile devices to access both 5G and 4G LTE networks at the same...
How should operators handle test and measurement as network automation is introduced?
Ask any 5G operator or vendor what the operational end-state of increasingly complex network and service models is supposed to be. They’ll likely tell you the goal is to automate anything that...
Private networks are expected to be one of the primary ways in which 5G services are monetized. A recent IDC forecast estimated that on a worldwide basis, private LTE/5G wireless infrastructure revenues will reach $8.3 billion by 2026, compared to $1.7 billion in 2021...
Proximity Services (ProSe), first introduced in Release 12 of the 3GPP specifications, is a D2D (Device-to-Device) technology that allows LTE devices to detect each other and to communicate directly.
In comparison to existing D2D and proximity networking technologies, ProSe offers a number of distinct benefits...
Cellular positioning was first introduced in the mid-nineties to meet regulatory requirements of emergency call positioning; since then, the possibilities for this feature have drastically expanded to address the needs of industrial verticals and use cases such as logistics, smart factories, autonomous vehicles, digital...
One of the new capabilities that is being introduced in 5G is integration of terrestrial networks with non-terrestrial networks (NTN), whether those are High-altitude Platforms (HAPS) flying the stratosphere, or satellites in low-Earth orbit (LEO) or geostationary orbit (GEO).
The ability to provide 5G...
As the 5G standard continues to evolve, one of the important aspects for increased sustainability, as well as prolonging device battery life, is power efficiency.
The recently frozen Release 17 builds upon previous releases in enabling 5G power saving features. That 5G power saving...
5G is becomes more broadly deployed across the planet, but the technology may also eventually end up in the skies. 3GPP has established, and is continuing to build upon, standards that will enable 5G services to be delivered over satellite infrastructure, otherwise referred to...
Coverage performance is key for mobile operators when commercializing 5G New Radio (NR) networks. Compared with LTE systems, NR systems operate at higher frequency bands, resulting in higher path loss and worse coverage performance.
According to Ericsson, the direct impact that coverage has on service...
5G is now mainstream, with more than 200 commercial 5G networks having already launched around the world and close to 1,000 5G devices already shipping—of which about half are non-smartphone devices, according to figures from the Global mobile Suppliers Association (GSA).
Those 5G New...
Rohde & Schwarz and Qualcomm will demonstrate the technology at CABSAT conference in May
One of the use cases being explored for 5G systems is that of remote media production. But the 5G standard also offers a built-in broadcast function, called 5G Broadcast/Multicast.
A broadcast or...
The move to Standalone 5G means technological and organizational changes with the latter perhaps more difficult
As some operators begin to operationalize Standalone 5G, it’s clear there are different strategies, based on spectrum deployment, network modernization and other factors, that inform this key network evolution....
According to 5G Americas, NR sidelink relay is the use of device-to-device communication as a way to extend the network coverage outside the area directly covered by the network infrastructure
NR sidelink relay was included as a working item in the 3GPP Release 17 to...
Qualcomm noted that further enhanced massive MIMO was one of the key areas of improvement in Rel-17
According to a report by Ericsson, Rel-17 MIMO enhancements address four areas: Beam management; multiple transmission and reception points (mTRP) for ultra-reliable, low-latency communication (URLLC); mTRP for enhanced...
Multimedia priority service (MPS) allows priority access to system resources to Service Users, creating the ability to deliver or complete sessions of a high priority nature
According to the 3GPP, the response to emergency situations (e.g., floods, hurricanes, earthquakes, terrorist attacks) depends on the communication...
