5gs Waveform Is A Battery Vampire - IEEE Spectrum Jul 2019
"Wireless standards are frequently updated, and in the next 5G release, the industry could address concerns that OFDM may draw too much power in 5G devices and base stations. That’s a problem, because 5G is expected to require far more base stations to deliver service and connect billions of mobile and IoT devices."

"So how did 5G get into a potentially power-guzzling mess? OFDM plays a large part ... OFDM has a high peak-to-average power ratio (PAPR)"

"One promising alternative that Yuan’s group is considering, non-orthogonal multiple access (NOMA), could deliver the advantages of OFDM while also overlapping users on the same spectrum."

Key ETSI official calls for reform of standards body - PolicyTracker: May 2019
"The mobile broadband global standards body, the 3GPP, could collapse under its own weight unless it changes its working practices, says European Telecommunications Standards Institute CTO Adrian Scrase.

He told the Brooklyn 5G Summit that the greater magnitude of work created by 5G is a big challenge for 3GPP. Not only has the technology become more sophisticated and complicated, but the number of interested stakeholders has increased. This is reflected by the number of input documents, which increased from around 100,000 in 2017 to 120,000 in 2018."

New security flaw impacts 5G, 4G, and 3G telephony protocols | ZDNet, Jan 2019
"A new vulnerability has been discovered in the upcoming 5G cellular mobile communications protocol. Researchers have described this new flaw as more severe than any of the previous vulnerabilities that affected the 3G and 4G standards."

"Further, besides 5G, this new vulnerability also impacts the older 3G and 4G protocols, providing surveillance tech vendors with a new flaw they can abuse to create next-gen IMSI-catchers that work across all modern telephony protocols."

According to "a research paper named "New Privacy Threat on 3G, 4G, and Upcoming5G AKA Protocols," published last year. ..., the vulnerability impacts AKA, which stands for Authentication and Key Agreement, a protocol that provides authentication between a user's phone and the cellular networks."

"Instead of intercepting mobile traffic metadata, this new vulnerability reveals details about a user's mobile activity, such as the number of sent and received texts and calls, allowing IMSI-catcher operators to create profiles for each smartphone holder."

"For example, two other academic studies from French and Finnish researchers also found that IMSI-catcher attacks are still possible against the upgraded 5G-AKA protocol, despite 3GPP's claims."

3GPP approves work item to bring 5G NR into unlicensed spectrum | FierceWireless Dec 2018
"3GPP agreed at its meeting in Sorrento, Italy, this past week to start a work item dubbed NR-U, which will define how 5G New Radio is introduced in unlicensed spectrum.

"The work item covers five scenarios with functionalities such as Carrier Aggregation (within one eNodeB), dual connectivity (across two eNodeBs), LTE anchor in licensed spectrum, 5G NR anchor in licensed spectrum, uplink only in licensed spectrum, downlink only in unlicensed spectrum as well as standalone operation..."

"Operators report big speed boosts after introducing LAA, a 3GPP Release 13 technology that uses carrier aggregation in the downlink to combine LTE in unlicensed spectrum (5 GHz) with LTE in licensed spectrum."

"Casaccia suggests that the ability to operate 5G NR standalone in unlicensed spectrum could lead to local private 5G networks dedicated for a specific application such as industrial IoT or mobile broadband for enterprises, or it could provide an avenue for service providers, like cable operators and ISPs or neutral host service providers in public venues such as sports stadiums and malls."

Editor’s Corner—CES recap: 5G steals some of the spotlight | FierceWireless
"the wireless industry has a lot more work ahead if it’s truly going to bring other industries into the 5G fold"

"5G, at least in my mind, will require far greater strides and tighter integration than ever before, and that’s going to require some innovative ways to get these other folks into the discussion"

"The industry must come together and make sure 5G provides valuable and unique opportunities for industries."

"I wouldn’t be surprised if the next big 5G panels include not only wireless companies but also their partners in other industries to show just how great an impact 5G is having on them. But until the industry builds some serious bridges with these other industries, it’s still just going to be a dog and pony show. If there’s anything that could go wrong with 5G, it might be the failure to bring these other industries fully on board."

3GPP work progressing to incorporate satellite industry in 5G | FierceWireless Jan 2018
"3GPP has studied the roles and benefits of satellites in 5G in Release 14, recognizing the added value that satellite coverage brings as part of the mix of access technologies, especially for mission-critical and industrial applications where ubiquitous coverage is crucial.
"According to 3GPP, the objective of TR 38.811 is to study channel models, to define the deployment scenarios as well as the related system parameters and to identify and assess potential key impact areas on the New Radio. In a second phase, it plans to evaluate and define solutions for the identified key impacts on RAN protocols/architecture.
"Another study item on using satellite access in 5G is being addressed in Working Group SA1, which will lead to the delivery of the corresponding Technical Report TR 22.822 as part of Release 16. That study will identify use cases for the provision of services when considering the integration of 5G satellite-based access components in the 5G system."

Understanding 3GPP – starting with the basics | Qualcomm
This is a subtle, but important organizational clarification. 3GPP is an engineering organization that develops technical specifications. These technical specifications are then transposed into standards by the seven regional Standards Setting Organizations (SSOs) that form the 3GPP partnership (as seen below in Figure 2). The regional SSOs are also responsible for establishing and enforcing an Intellectual Property Rights (IPR) policy.

New ETSI mobile/broadcast group to focus on convergence — PolicyTracker: the spectrum management newsletter
Although the group is an industry standardisation group (ISG) under the auspices of ETSI, its chair Simon Fell told PolicyTracker its members are to use it as a vehicle to form study programmes on the topic, rather than to work on new standards.

One senior source from the mobile industry told PolicyTracker that “there has been rather a proliferation of ISGs of late. They are a rather curious beast – under the ambit of a standards organisation, but not allowed to make technical standards”.

He said the relatively small and diminishing resources of operators for standards activities must be targeted at the most important efforts and that “these small activities set up in unexpected places are often established in the hope of shifting the balance between different sectors”.

3GPP settles on “harmonised” Internet of Things work item - PolicyTracker Oct 2015
Global telecoms standardisation body the 3GPP has decided on its approach to a narrowband Internet of Things (IoT) solution for mobile operators. NB-IoT, as it is known, will be able to operate in three modes: = Stand-alone operation = Guard band operation = In-band operation. All three of these modes will use a bandwidth of 180 kHz, with 15 kHz sub-carrier spacing – and all of them will be based on OFDM (orthogonal frequency-division multiplexing) in the downlink.

GSM Evolution can benefit from GSM 900 MHz installed base - PolicyTracker Nov 2014
"There are several pieces of work being studied for the Internet of Things (IoT) within the cellular standardisation body, the 3GPP. A few months ago, PolicyTracker reported on competition between the LTE-M approach, which is now a work item in 3GPP TSG RAN, and the "clean slate" approaches to IoT, which are currently being studied in 3GPP's GERAN specification group." "In order to become a 3GPP standard, an initiative has to graduate from being a study item to a work item. Traditionally, 3GPP requires four companies to support an initiative for it to become a work item. PolicyTracker understands that Nokia Networks supports GSM Evolution but is focussing its cellular IoT efforts on the LTE-M programme. Whether GSM Evolution can become a work item in time for 3GPP Release 13 is unclear." "There was consolidation among advocates for a clean slate approach to the IoT in September as telecoms giant Huawei acquired UK-based Neul for a sum that PolicyTracker understands to be in the r"

"Leading public mobile network operators want to enter the Internet of Things (IoT) market, but they vehemently disagree over how this can be done. Nokia Networks and Ericsson argue that the IoT can be accommodated by LTE's evolving standards, whereas Huawei and Neul insist that a “clean-slate” approach would be more appropriate."

3GPP Conference: LTE in unlicensed spectrum, June 13, 2014, Sophia Antipolis
includes links to slides "Initial focus will likely be on Licensed-Assisted Carrier Aggregation operation to aggregate a primary cell, using licensed spectrum, to deliver critical information and guaranteed Quality of Service, and a co-located secondary cell, using unlicensed spectrum, to opportunistically boost datarate." "Fair coexistence between LTE and other technologies such as WiFi as well as between LTE operators is seen necessary." Dino Flore noted; “Initial results suggest that, when augmented with the appropriate coexistence mechanisms to operate in unlicensed spectrum, e.g. Listen-Before-Talk, LTE can effectively coexist with Wifi and outperform it in terms of spectral efficiency”

Work to avert rail-mobile interference in Europe continues — PolicyTracker Sep 2013
The proximity of GSM-R and public mobile networks has already caused interference between UMTS users of these bands and GSM-R in around 250 locations across Europe. This happens because receivers are desensitised, blocked or overloaded. In principle, this could have happened for GSM but is set to accelerate when LTE is rolled out across the bands. Conversely, because LTE, like UMTS, is a wideband technology, it is predicted that public mobile networks will be worse affected than GSM-R. A series of possible solutions were set out in 2011 in ECC Report 162. These measures range from frequency hopping for public mobile networks to tilting antennas but ultimately it is completely down to the national governments, railway operators and mobile network operators to sort it out for themselves. ... are in general two prominent solutions; filters [for transmitters] and improved receivers"

Small cell deployment faces spectrum and regulatory challenges — PolicyTracker - April 2013
"As the deployment of small cells around the world accelerates, industry body the Small Cell Forum is finding it has to deal with a raft of regulatory and spectrum issues, often on a country-by-country or even a case-by-case basis." "the Forum feels the most sensible medium- to long-term solution to overcome spectrum-related barriers to mass small cell deployment is for a specific band to be internationally harmonised as an exclusive small cell band. Most of the discussions are focusing on the 2.3 GHz band." "... X2 interface, which has been released by the 3GPP. The IMT Advanced specification setters have devised an interface that allows femtocells to have their own self-organising capacity, adjust their own power levels and detect other femtocells, and adjust amongst themselves as a group.

A survey on 3GPP heterogeneous networks - IEEE Xplore

As the spectral efficiency of a point-to-point link in cellular networks approaches its theoretical limits, with the forecasted explosion of data traffic, there is a need for an increase in the node density to further improve network capacity. However, in already dense deployments in today's networks, cell splitting gains can be severely limited by high inter-cell interference. Moreover, high capital expenditure cost associated with high power macro nodes further limits viability of such an approach. This article discusses the need for an alternative strategy, where low power nodes are overlaid within a macro network, creating what is referred to as a heterogeneous network.

3G and 4G Wireless Blog: Advanced 3GPP Interference Aware Receivers = Jul 2008
"Receiver structures in UEs and Node-Bs are constantly being improved as products evolve and more complex features are added to HSPA. The result is improved system performance and higher user data bit rates. This trend is reflected in constantly changing UE receiver requirements in 3GPP. In 2006, 3GPP has studied further improved minimum performance requirements for UMTS/HSDPA UEs. These enhanced performance requirements are release-independent (i.e. apply also to a Rel-6 terminal with advanced receivers)."
