In frequency division duplex (FDD) massive MIMO systems, each user equipment (UE) device typically feeds back downlink channel state information (CSI) to its serving base station (BS), which may then be utilized for beamforming and scheduling purposes. However, the large number of antennas increases the CSI signaling overhead in the...

"Compressed beamforming algorithm is used in the current Wi-Fi standard to reduce the beamforming feedback overhead (BFO). However, with each new amendment of the standard the number of supported antennas in Wi-Fi devices increases, leading to increased BFO and hampering the throughput despite using compressed beamforming. In this paper, a...
Distributed ledger technology, with its multitude of advantages including immutability, transparency, decentralization, and security, have excellent potential to promote and even revolutionize future 6G mobile networks. Large-scale distributed ledger deployment within or for mobile networks relies on distributed ledger-focused standards to facilitate and ensure interoperability. The European Telecommunications Standards (ETSI)...
What defines a good versus a bad sensory experience –particularly if you want to charge a premium for it? That’s a difficult question when physical, digital and virtual worlds merge. It depends on a human’s subjective perceptions as well as a network’s capabilities. Human-centered quality metrics are urgently needed to...
With the increasing number of commercial 5G deployments, research on Beyond 5G (B5G) and 6G has started in earnest. Although it is too early to safely claim what 6G systems will look like or how they will be designed, it is certain that 6G systems will support new use cases...
Cellular technology evolution across multiple generations has consistently sustained the global economic growth. Each of these generations has uniquely contributed to boosting the world Gross Domestic Product (GDP) by addressing key industry pain-points and enabling new business opportunities not possible with previous generation networks. 6G will not be an exception...
Joint communication and sensing allows the utilization of common spectral resources for communication and localization, reducing the cost of deployment. By using 5G New Radio (NR) (i.e., the 3rd Generation Partnership Project (3GPP) Radio Access Network for fifth generation) reference signals, conventionally used for communication, sub-meter precision localization is possible...
Blockchain technology is a technology that jointly leverages and builds on top of a few existing techniques such as cryptography, hashing, Peer-to-Peer (P2P) networking, smart contract, and consensus protocols. Fully distributed control and management capability of the 5G/6G wireless systems may be enabled by blockchain technology, especially in the untrusted...
In this presentation we’ll talk about the development of Beam Management and describe the system attributes related to performing the initial beam establishment. We will also review the supported 3GPP requirements and limitations of the current implementation. We’ll then share some details about the beam management implementation done on the...
Drawing from pioneering research from the EPIC project, InterDigital’s Onur Sahin details in Embedded.com why the digital baseband is a critical component to unlock THz communications, and how this research lays a foundation for achieving the potential of 6G. In his editorial, Onur explains that the digital baseband processor is...
Though some have touted 5G as the “last G,” it is when deployments begin that limitations are revealed and the contours of the next generation of wireless take shape. These limitations are made especially clear as we lead research projects and develop testbeds to examine new use cases and technologies...
