Speech Title: A New Approach to Real-Time Optimal Scheduling in 5G
Abstract: When addressing optimal scheduling in 5G cellular networks, a key technical challenge is to find an optimal or near-optimal scheduling solution in real-time. Existing schedulers designed for 4G LTE cannot meet the new timing requirements in 5G due to smaller time intervals in 5G numerologies. In this talk we present a GPU-based proportional-fair (PF) scheduler for 5G NR, which can offer near-optimal scheduling solution in real time(e.g., ~100 μs time scale). The key ideas in our solution design include (i) decomposing a large-scale complex optimization problem into a massive number of small and independent sub-problems; (ii) selecting a subset of sub-problems from the most promising search space through intensification and random sampling; and (iii) fitting the selected subset of problems into GPU processing cores for very simple computation. I will share our experience
in this research and show the design of GPF – a GPU-based proportional fair (PF) scheduler that can meet the 100μs time requirement. By implementing our proposed GPF on an off-the-shelf NVIDIA Quadro P6000 GPU, we show that GPF is able to achieve near-optimal performance while meeting the 100 μs time requirement. Our design experience shows that a GPU-based parallel computing holds the potential to design optimal schedulers for current and future generations of telecommunication systems.

Speech Title: Optical Fiber Technologies
Abstract: Optical fiber-based devices have been widely deployed in recent years. There are many advantages of using fiber as a sensor. These include electrically-passive operation, light weight, immunity to radio frequency interference and electromagnetic interference, high sensitivity, compact size, corrosion resistance, easily multiplexing and potentially low cost. Several novel fiber-based sensors and technologies developed are presented here, including fiber Bragg grating (FBG) based sensors, photonic crystal fiber (PCF) based sensors, specialty fiber-based sensors and distributed fiber sensing systems. FBGs as instinctive sensors, are ingeniously designed as two-dimensional (2D) tilt sensors, displacement sensors, accelerometers and corrosion sensors here; PCF based evanescent field absorption sensor, PCF induced Mach-Zehnder interferometer and Fabry-Perot refractometer for temperature and refractive index sensing are presented; based on localized surface Plasmon resonant (LSPR) effect, nano-sized fiber tip with gold nanoparticles are demonstrated for live cell index bio-sensing applications.
