Scope and Rationale
The millimeter wave frontier of wireless communications offers higher frequencies, wider bandwidths, and larger numbers of antennas and radio-frequency (RF) chains. Similarly, massive multiple-input multiple-output (MIMO) systems together with carrier aggregation at microwave frequencies provide tremendous dimensionality. However, state-of-the-art radio architectures with high resolution and linearity prevent us from leveraging all of these benefits at once because of excessive cost and power consumption. One wave of research and development to address these challenges has focused on so-called hybrid arrays, with a large number of antennas connected through phase-shifting arrays to a smaller number of linear RF chains to reduce power consumption of the array as a whole. This semi-analog approach, however, reduces the overall robustness and versatility of these systems. This workshop thus seeks to boost another wave of innovation focusing on low-resolution, non-linear RF chains, signal processing techniques, and system designs to reduce cost and power consumption per chain, and thereby allow the number of RF chains to scale up to the number of antennas. Fully digital control of beamforming weights or precoding vectors would allow for high mobility, robustness to non-line-of-sight channels, and ultra-reliable low latency applications even at millimeter wave frequencies.
This workshop aims to bring together researchers with interest and the complementary expertise in communication circuits, algorithms, and systems required to formulate and solve these foundational problems. We posit that the workshop will provide a common platform for wireless service providers, network equipment and device manufacturers, as well as academia to foster collaboration and to promote practical and impact research in this area.
