Latency Guarantee for Ubiquitous Intelligence in 6G: A Network Calculus Approach

Given 6G's extremely variable deterministic nature, THz channel tail morphology, and delay distribution tail characteristics created by the UBiI random component, this paper seeks to determine the most effective solution that minimizes the end-to-end delay of UbiI from start to end. In this paper, the arrival curve and service curve of network calculus can be used to well illustrate the stochastic nature of wireless channels, the tail behavior of wireless networks, and the E2E service curve of network calculus can accurately represent the tail distribution in UbiI. We recommend the hierarchical architecture, the network model, and the service delay model of the UbiI system based on network calculus at Then.

Rate-Splitting Multiple Access for 6G -- Part II: Interplay with Integrated Sensing and Communications

To a moving target, we introduce a general RSMA-assisted ISAC architecture, in which the ISAC router has the ability to simultaneously communicate with downlink users and probe detection signals. Both then and the communications technologies are respectively introduced, followed by a RSMA-assisted ISAC waveform design example that simultaneously minimizes the Cramer-Rao bound of target estimation and maximizes the minimum fairness rate amongst communication users exposed to the per-antenna power constraint.

Rate-Splitting Multiple Access for 6G -- Part III: Interplay with Reconfigurable Intelligent Surfaces

RSMA and RIS, two proposed PHY layer technologies, first including the ability of integrating RSMA and RIS, as well as how they could aid each other. We'll start by discussing the major benefits of RIS-aided RSMA networks and plotting the rate region of RIS-aided RSMA networks for both ideal and poor channel conditions. In summary, RSMA is a promising technology for next generation multiple access and future networks such as 6G and beyond.

Physical Layer Security for 6G Systems why it is needed and how to make it happen

In this context, quality of protection is viewed as a highly customizable security framework for future networks with a multitude of non-functional requirements. Different service levels could be conceptualized, reflecting the emerging services networking paradigm, leading away from static security controls, which are currently embedded in zero-trust security architectures. For the first time, we see the integration of physical layer defense schemes in 6G security protocols, which would include security checks at all levels.

Cost-Efficient and QoS-Aware User Association and 3D Placement of 6G Aerial Mobile Access Points

To ensure ubiquitous network coverage, 6G networks need a flexible infrastructure in order to dynamically deliver ubiquitous network coverage. We present our joint 3D MAP deployment and user association problem with a dynamic network facing interference and mobility constraints in this paper. MAPs provide high Quality of Service connectivity to mobile ground users in mmwave or sub-6GHz bands and find their optimal positions in a 3D grid. Multiple users can be linked to multiple MAPs under interference pressure, according to a deep multiagent reinforcement learning scheme that is available for both MAPs under constraint.

La Résistance: Harnessing Heterogeneous Resources for Adaptive Resiliency in 6G Networks

Those critical applications designed to shield human life are now available over wireless networks in recent years. The gap in terms of the first two aspects is expected to be filled by 6G wireless networks, but providing ultra-high reliability is a wide open challenge. We can imagine the bold theme of La Résistance 6G at this moment, which will allow for the introduction of mission-critical applications and services over 6G networks. However, some disruptions, such as when a cut-vertex malfunctions or when the disruption causes the application to fail without access to a standby generator, can be crippling. They must continue to achieve their mission goals in the midst of a disruption to human life. We outline the obstacles that lie between our LR6G vision and outline the challenges that may be hindered in achieving this goal in this paper.
