3GPP’s Release 16 timeline hangs in the balance thanks to coronavirus – Telecoms.com
“When experiments with e-meetings have happened in the past it is very easy for discussion to spiral and go quite tangential,” one insider told Telecoms.com. “90% of the negotiation to reach agreements on contentious topics happen over coffee, lunch and dinner… you don’t get that opportunity in an e-meeting.”

As a result of the coronavirus outbreak, all Technical Specification Group (TSG) and Working Group (WG) meetings have now been replaced with electronic meetings for the first quarter. 3GPP has said this is only applicable where practical, and when not, presumably the meeting is cancelled.

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."

IEEE 802.11 Coexistence Workshop
The primary objective of the Coexistence Workshop is to discuss issues related to fair and efficient shared operation by IEEE 802.11ax High Efficiency WLAN), IEEE 802.11be (Extremely High Throughhput) and 3GPP NR-U (New Radio Unlicensed) in the 6Ghz band, including:

Sharing information on plans for use of future technology standards (particularly IEEE 802.11 and 3GPP NR-U) in the 6 GHz band

Assessing coexistence issues and topics related to the simultaneous use of IEEE 802.11 and 3GPP NR-U technologies in the 6 GHz band, including coexistence criteria and mechanisms

Discussing other related coexistence topics of interest, including deployment experience of 3GPP LAA/eLAA coexistence with IEEE 802.11ac in the 5GHz band.

Cellular networks - 3GPP etc.
"At the @EnigmaConf EFF panel a few months ago, @JoeBeOne asked a very good question: how we should think about cell networks differently than Internet networks?"

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."

5G NR gNB Logical Architecture and It's Functional Split Options - Techplayon
Option 7 (Intra PHY split): Multiple realizations of this option are possible, including asymmetrical options which allow obtaining benefits of different sub-options for UL and DL independently.

This option requires some kind of compression technique to reduce transport bandwidth requirements between the DU and CU.

In the UL, FFT, and CP removal reside in the DU and for the two sub-variants, 7-1 and 7-2 are described below. Remaining functions reside in the CU.
In the downlink, iFFT and CP addition reside in the DU and the rest of the PHY resides in the CU.
Considering above there are three sub-variant available for this option described as below

Option 7-1 In this option the UL, FFT, CP removal and possibly PRACH filtering functions reside in the DU, the rest of PHY functions reside in the CU. In the DL, iFFT and CP addition functions reside in the DU, the rest of PHY functions reside in the CU.

Option 7-2 In this option the UL, FFT, CP removal, resource de-mapping and possibly pre-filtering functions reside in the DU, the rest of PHY functions reside in the CU. In the DL, iFFT, CP addition, resource mapping and precoding functions reside in the DU, the rest of PHY functions reside in the CU.

Option 7-3 (Only for DL): Only the encoder resides in the CU, and the rest of PHY functions reside in the DU.

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."
