Handover (mobility) is a process of transferring an ongoing communication session of a user equipment (UE) from one cell (i.e., base station or gNodeB (gNB)) to another cell in connected state. The primary motivation behind handover is to ensure seamless connectivity and continuity of service for the user, especially while the user is on the … Read more
In 3GPP Release 17, the Non-Terrestrial Network (NTN) work item was introduced. The NTN refers to a network or segment of networks using radio frequency (RF) resources on board a satellite (or Unmanned Aerial System (UAS) platform). The key concept in the NTN is that the NTN cells are provided from Non-Geostationary Orbit (NGSO) satellites, … Read more
The 6G Symposium of Fall 2022 was held on the 11th and 12th of October at the Hotel Washington in Washington, DC. The symposium was organized in partnership with NextG Alliance – of which Ofinno is a founding and full member – together with Interdigital, Northeastern University, and Keysight. Thought leaders across industry, government, and … Read more
SungDuck Chun Author Overview The 5G system achieves a breakthrough increase in the key performance indicator of communication systems, compared to the previous generation 4G system. In addition, the 5G system introduced new functionalities supporting various emerging application scenarios. Based on the success of the 5G system, the 6G system is likely to emerge around … Read more
Mohammad G. Khoshkholgh D. Author This paper provides an overview of the current standardization progress in the 3rd Generation Partnership Project (3GPP) targeting integration of the satellite access network with New Radio (NR). It also discusses several impacted areas of NR, particularly in the physical layer and MAC layer, for incorporation of the satellite access … Read more
Reliable access to broadband services for every person (and everything) everywhere has been a reoccurring discussion for developing any modern cellular technologies. Despite substantial successes of 4G and 5G cellular systems, there are still unserved and underserved populations. Measurements reveal up to 400 million people around the world still encounter difficulties to enjoying stable and … Read more
Non-terrestrial network (NTN) is an umbrella term that encompasses cellular communication networks served by base stations floating in air. Low orbit flying objects, such as drones and uncrewed aerial vehicles (UAV) to higher orbit satellites make up the majority of NTN enablers. NTN may also include flying end-users, for example, airplanes in an air-to-ground (ATG) … Read more
The U.S. Department of Commerce (DOC) recently announced their 2022-2026 Strategic Plan. This plan centers around five key goals, the first of which is to drive U.S. innovation and global competitiveness. The strategy aims to “equip workers and companies to compete across the globe and attract foreign investment,” and solidify the country’s leadership in emerging … Read more
Hyukjin Chae Author Overview In the existing wireless communication systems, it has been studied about how quickly and how many packets could be delivered in time to how many devices. Beyond fifth generation (B5G) or sixth generation (6G) wireless communication systems can operate as a sensor for recognizing surrounding environments or objects as well as … Read more
Beam management has been one of the key enabling technologies employed in 5G new radio (NR) systems. This article discusses how the beam management mechanisms in 5G NR have been evolved, the current paradigm shift toward unified/common beam management, and other application scenarios jointly, to be optimized with the common beam management technology in Rel-17 … Read more
