Next Generation Wireless Systems

Next Generation Wireless Systems

Researchers at the University of Florida, North Carolina State University and State University of New York (SUNY) Stony Brook are collaborating to create novel frameworks to enable 5G/6G network interoperability, under a project award from the National Science Foundation.

The main contribution of the project is the design and implementation of a novel spectrum orchestrating framework, referred to as MAC-on-MAC (MoM), such that MAC solutions can be viewed in a panoramic way to coordinate spectrum access through a `centralized’ control plane. This design approach is fundamentally different from single-system single-layer solutions. An SDN-like flow-based approach is being designed for layer 2 to handle access and resource requests from both upper and lower layers, for both single-RAT-assigned user frames and multi-RAT MoM controller processed frames.

Project Goal:
Wireless systems with different radio access technologies (RATs) are becoming packed tightly in the space of radio spectrum. The carrier frequency and channel bandwidth of these systems, however, are drastically different across the spectrum domain, e.g., the IEEE 802.11 family that operates at 900 MHz, 2.4/5 GHz, and 60 GHz (mm-wave) bands, the 3GPP 5G family that spans 6-100 GHz, and more. This project mitigates the incoherent and disassociated frequency bands of the multi-RAT coexisting environments by exploiting the potential of cross-layer design from the circuits of transmitter and receiver, to the MAC layer with an innovative MAC-on-MAC spectrum control plane. This project has four major thrusts: (i) design of innovative transmitter and receiver techniques for energy-efficient multi-band spectrum monitoring; (ii) using custom bio-inspired spectrum sensors to create a multi-band sensing solution; (ii) methods to acquire complete spectrum occupancy information with a limited number of measurements; (iii) algorithms for obtaining a sorted ranking of paths that map a data flow to a range of spectrum slips; and (iv) creating MAC-Flow, a flow based network protocol that is capable of handling networking demands from both upper and lower layer, for both traditional user frames and for MAC-on-MAC controller processed frames.
