One of the key enhancements currently being done relates to the support for multicast/broadcast, or point-to-multipoint (PTM) transmissions, with a key focus on enhanced reliability. These new features are targeting a wide variety of use cases ranging from network-to-vehicle communication to immersive multimedia content delivery. In this work, we present some of the key physical layer procedures and enhancements that were standardized to support the group scheduling of users for multicast traffic with near-unicast level of reliability, as well as support for idle/inactive users to receive broadcast traffic. We also present some performance results, which validate the need to support NACK-only HARQ feedback for multicast which provides significantly improved radio resource efficiencies for uplink feedback, with comparable performance as currently defined ACK/NACK feedback.","PeriodicalId":505795,"journal":{"name":"IEEE Communications Standards Magazine","volume":"47 13","pages":"44-51"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140279879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, urban air mobility, one of the driving use cases of AAM, employs electrical vertical takeoff and landing aircraft to offer efficient and on-demand air transportation for goods as well as human passengers. Key stakeholders, such as original equipment manufacturers, prospective AAM operators and communications service providers are exploring suitable technologies to meet various service, safety, and sustainability requirements. In this article, we discuss the most important AAM use cases and associated requirements from a cellular connectivity perspective and summarize the Third Generation Partnership Project (3GPP) standardization activities addressing these requirements. While previous works have investigated the role of cellular connectivity for command and control of uncrewed aerial vehicles, other types of AAM vehicles, such as flying buses or flying taxis likely impose more demanding requirements due to higher flying altitudes and demands for mobile broadband services for crew members and passengers. Therefore, we evaluate the performance of beamforming alternatives that are applicable for providing cellular connectivity in AAM scenarios. The results show the benefits of 3GPP standardized and to-be-standardized features, such as codebook-based beamforming, multi-user multiple-input multiple-output systems, and user equipment directional antennas in cellular networks with mixed terrestrial and aerial users.","PeriodicalId":505795,"journal":{"name":"IEEE Communications Standards Magazine","volume":"62 ","pages":"65-71"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140276012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major challenges include the reliance on global positioning system (GPS), whose signals are not received well in some locations, and the inferior user experience caused by the lack of information about unknown surroundings. This article describes the design and development of a markerless augmented reality-based pedestrian navigation system that can handle navigation even in the absence of GPS signals. It improves the user experience by providing a novel landmark recognition feature, which allows users to identify nearby buildings or streets during navigation. To mitigate the absence of GPS signals, a novel user localization method utilizing a step count-based distance estimator is proposed. The experimental results show the location accuracy of 2.3 meters on average and the increase in step count detection accuracy of nearly 0.5% in comparison with existing technologies available in smartwatches, and an average latency of 74 milliseconds in system response in an urban environment. The proposed solution can be used as a mobile application on smartphones and has the potential to contribute to the smart city-related standardization activities of ITU-T Study Group 16.","PeriodicalId":505795,"journal":{"name":"IEEE Communications Standards Magazine","volume":"283 ","pages":"20-26"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140278147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
