It targets low power, long range, low cost communication using unlicensed spectrum. Network topology is collaborative, which reduces a lot protocol signalling compared to a cellular network. The device is connected to a network server, and protocol overhead is limited to 13 bytes for any data frame. There are three classes of operation. Class A is optimized for low power operation of end-devices, while class B and class C offer reduced downlink latency. The protocol specification offers several mechanisms to adjust the link layer parameters: adaptive data rate, adaptive power control, variable repetition rate, and channel selection.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"9 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/10251929/10255463/10255464.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68113986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NR Sidelink (SL) Work Item in Release 17 includes several key features targeting reliability enhancements, power saving and coverage enhancements by expanding the scope of NR sidelink to target V2X, commercial D2D use-case and Public safety. This paper provides an insight on the current 3GPP Release 17 NR SL design describing necessary enhancements in the physical, protocol layer to support inter-UE coordination message for reliability enhancement for autonomous resource selection procedure by providing feedback on the half-duplex, persistent collision and hidden nodes. In addition, the power saving feature is addressed by introducing a SL DRX mechanism for the PC5 interface which defines active reception and transmission periods between a TX and the peer Rx UE(s) and also between Tx UE and gNB. Furthermore, this paper outlines details on the Sidelink Relay feature for coverage enhancement by describing possible solutions for UE to Network relay and UE to UE relay.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"9 2","pages":"79-90"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/10251929/10255460/10255490.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68121009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even if the initial 5G networks, basing on the 3GPP Release 15, have hardly started become commercially available gradually as of 2019 and their large-scale deployment is still years away, industry is already keen to envision the justification and performance of the forthcoming generation. While there are no concrete 6G standards produced at this stage, their planning will benefit from realistic indications of the requirements and type of usage. The task is not straightforward as users, including a variety of verticals with their rather different communication environments, are sometimes not capable of expressing their future needs in technical terms nor industry might be able to prognosticate the demand that has not yet equivalence in preceding systems. This paper analyses some of the most important current visions of key standardization bodies and assesses indications of the industry for the potential requirements, service types, use cases, and architectural and functional models that can serve as a building block for the actual realization of the visions. This paper also presents means that can be applied in further interpretation and assessment of the vertical needs and priorities, with examples reflecting the benefits of Network Slice requirements that the GSMA North Americas Network Slicing Taskforce studied for foreseen near future environment and that may be extended to be utilized also in exploration of 6G requirements.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"9 3","pages":"311-325"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/10251929/10255453/10255475.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68097850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it was decided to split the work in two phases. The 5G Phase 1 work focused on the foundation of the new system while 5G Phase 2 focused more on the needed enhancements to address the use cases. The work on the security in 5G Phase 1 was ample enough to deliver all the needed mechanisms not only to secure the communication between the different entities but also to protect the privacy of the user. Therefore, it is expected that the work on 5G Phase 2 will unlikely have impact on the security mechanisms. Nevertheless, some of the new features in 5G Phase 2 give rise to subtle security challenges which may require enhancements to the existing mechanisms. In this article, we consider some of the 5G Phase 2 features and shed light on such security aspects.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"8 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/10251929/10258063/10258087.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68106280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The European funded project StandICT.eu aims at supporting European experts' presence in and contributions to international standardisation activities in ICT. The focus of the project is on the 5 priority domains identified by the European Commission (Cloud Computing, IoT, Big Data, Cyber Security, 5G) and on Artificial Intelligence while being open for other relevant topics defined in the annual European Rolling Plan for ICT Standardisation. The project has two main outcomes: (i) increased contribution of European experts in international standardisation through support by providing grants for planned contributions of successful applications of experts, and (ii) an online observatory of published standards and ongoing standardisation activities in the areas mentioned before. This observatory (called Standards Watch) is accessible through the project's web site and open for contributions and comments from registered users. As part of the effort for the Standards Watch the projects has prepared a comprehensive analysis of the international standardisation landscape in the AI field, that comprises a description of the ICT standards and ongoing work at international level in the field of AI across the standardisation organisations already active in the field. In this article we will present results of our work where we have analysed the work of the 5 international and European Standards Development Organisations (SDOs) IEEE,\u0000¹\u0000¹\u0000Institute of Electrical and Electronics Engineers [13].

{"title":"Questioning the Scope of AI Standardization in Learning, Education, and Training","authors":"Jon Mason;Bruce E. Peoples;Jaeho Lee","doi":"10.13052/jicts2245-800X.822","DOIUrl":"https://doi.org/10.13052/jicts2245-800X.822","url":null,"abstract":"Well-defined terminology and scope are essential in formal standardization work. In the broad domain of Information and Communications Technology (ICT) the necessity is even more so due to proliferation and appropriation of terms from other fields and public discourse - the term ‘smart’ is a classic example; as is ‘deep learning’. In reviewing the emerging impact of Artificial Intelligence (AI) on the field of Information Technology for Learning, Education, and Training (ITLET), this paper highlights several questions that might assist in developing scope statements of new work items. While learners and teachers are very much foregrounded in past and present standardization efforts in ITLET, little attention has been placed until recently on whether these learners and teachers are necessarily human. Now that AI is a hot spot of innovation it is receiving considerable attention from standardization bodies such as ISO/IEC, IEEE and pan-European initiatives such as the Next Generation Internet. Thus, terminology such as ‘blended learning’ necessarily now spans not just humans in a mix of online and offline learning, but also mixed reality and AI paradigms, developed to assist human learners in environments such as Adaptive Instructional Systems (AIS) that extend the scope and design of a learning experience where a symbiosis is formed between humans and AI. Although the fields of LET and AI may utilize similar terms, the language of AI is mathematics and terms can mean different things in each field. Nonetheless, in ‘symbiotic learning’ contexts where an AIS at times replaces a human teacher, a symbiosis between the human learner and the AIS occurs in such a way where both can exist as teacher and learner. While human ethics and values are preeminent in this new symbiosis, a shift towards a new ‘intelligence nexus’ is signalled where ethics and values can also apply to AI in learning, education, and training (LET) contexts. In making sense of the scope of standardization efforts in the context of LET based AI, issues for the human-computer interface become more complex than simply appropriating terminology such as ‘smart’ in the next era of standardization. Framed by ITLET perspectives, this paper focuses on detailing the implications for standardization and key questions arising from developments in Artificial Intelligence. At a high level, we need to ask: do the scopes of current LET related Standards Committees still apply and if not, what scope changes are needed?","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"8 2","pages":"107-122"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/10251929/10258069/10258062.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68009015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We begin by examining the validity of grounding standards that aim for international reach on human right agreements, and the need to accommodate variations in prioritization and tradeoffs in implementing rights in different societal and cultural settings. We then examine the major recent proposals from the OECD, the EU and the IEEE on ethical governance of Trustworthy AI systems in terms of their scope and use of normative language. From this analysis, we propose a preliminary minimal model for the functional roles relevant to Trustworthy AI as a framing for further standards development in this area. We also identify the different types of interoperability reference points that may exist between these functional roles and remark on the potential role they could play in future standardization. Finally we examine a current AI standardization effort under ISO/IEC JTC1 to consider how future Trustworthy AI standards may be able to build on existing standards in developing ethical guidelines and in particular on the ISO standard on Social Responsibility. We conclude by proposing some future directions for research and development of Trustworthy AI standards.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"8 2","pages":"123-150"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/10251929/10258069/10258095.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68140334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
