PROJECT TITLE :

Asynchronously Coordinated Multi-Timescale Beamforming Architecture for Multi-Cell Networks - 2018

ABSTRACT:

Modern wireless devices like smartphones are pushing the demand for higher wireless knowledge rates. The ensuing increase in wireless traffic demand will be met by a denser deployment of access points, coupled with a coordinated deployment of advanced physical layer techniques to cut back inter-cell interference. Unfortunately, advanced physical layer techniques, e.g., multi-user (MU) MIMO found in 802.11ac and LTE-advanced, aren't designed to control efficiently in a coordinated fashion across multiple densely deployed transmitters. In this Project, we tend to introduce a brand new coordination architecture, which will achieve high performance gains without the high overhead and deployment value that typically comes with coordination, therefore creating the vision of high capacity wireless access via densely deployed transmitters sensible. The basic plan is to loosely coordinate nearby transmitters using slow varying channel statistics, whereas keeping all the functionality that depends on fast varying channel state information and has tight time deadlines locally. We tend to achieve this via a good combination of analog and digital beamforming using inexpensive front ends, a provably efficient algorithm to pick out compatible users and analog beams across all transmitters, and backward compatible protocol extensions. Our performance results, that embody analysis, simulations, and experiments with software outlined radios and directional antennas, show that our approach will achieve the 10× gains of the theoretically optimal coordinated MU-MIMO approach, without the need to either tightly coordinate the clocks of the remote transmitters or meet tight delay constraints.
