What is low-power wake-up signal (WUS)?

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....

How is security foundational to private 5G?

Private 5G networks change the security landscape, these experts contend, by converging siloed cellular, IoT and enterprise security needs.

What is service function chaining (SFC)?

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...

The future of 5G: What’s left to do, and what lies ahead in 6G?

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...

What is Minimization of Drive Tests (MDT) in 5G?

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...

Six operational challenges for 5G

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...

What is 5G ENDC?

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...

Network automation vs. network autonomy: 5G, trolleyology, and Captain Sully

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...

Q&A: The basics of private 5G networks

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...

What 5G proximity based services are in Release 17?

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...

What 5G NR positioning enhancements are in in Rel-17?

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...

Four types of challenges for 5G non-terrestrial networks

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...

Three 5G power-saving aspects of Release 17

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...

Seven use cases for 5G NR over non-terrestrial networks

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...

What 5G NR coverage enhancements are in Release 17?

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...

What’s new and improved in 5G Release 17?

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...

What is 5G Broadcast/Multicast?

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...

How to deploy Standalone 5G—strategies and considerations

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....

What is mTRP for eMBB?

mTRP for eMBB is a MIMO technique that will help 5G mmWave deployments deliver predictable 5G broadband service at scale.

What is 5G NR sidelink relay?

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...

What is a Virtual Private Cloud?

A Virtual Private Cloud can help enterprises leverage public cloud economy of scale while keeping corporate data secure.

What is further enhanced MIMO (FeMIMO)?

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...

Why is beam management key to 5G?

5G New Radio (NR)'s massive MIMO and beam management support are both essential to 5G mmWave carrier deployment strategies.
