Keynote 2: Scaling Up Antenna Arrays, Carrier Frequency and Bandwidth for Low Latency Communications and Massive Connectivity Beyond 5G
Speaker: Dr. Danijela Cabric, UCLA
Abstract: Future generations of cellular and IoT networks will operate in the upper millimeter wave (mmW) frequency band where ≥ 10 GHz bandwidth can be used to meet the ever-increasing demands. While these abundant spectrum resources have been leveraged to increase data rates in 5G cellular, the next goal is to further diversify 5G performance for applications requiring low latency, high reliability, and massive connectivity. These new requirements demand fundamental rethinking of radio architectures, signal processing, and networking protocols to address challenges of extremely wide bandwidths, large antenna array sizes, and high cell density at mmW frequencies.
In this talk, we will discuss latency and connectivity bottlenecks from a physical layer and network layer perspective in the context of mmW propagation where the beamformed initial access, beam training and tracking are critical for reliability and coverage. While increasing the antenna array size and bandwidth in principle provide benefits of improved SNR and capacity, at the same time the hardware complexity and radio impairments require careful design of the signal processing algorithms. We will introduce a novel analog True-Time-Delay (TTD) antenna array as a truly ultra-wideband scalable antenna array architecture and demonstrate its unique frequency-dependent beamforming modalities for fast beam training and channel estimation, massive IoT connectivity and flexible beam to sub-band assignment for cellular OFDMA transmission.
