MIMO 2015 - Workshop on Advancements in Massive MIMO

Due to explosive increase of smart phones and tablets usage, drastic growth of mobile data traffic has been observed in
recent years. To cope with this high rate of traffic growth, the wireless industry has started looking into future 5G
technologies to improve spectral efficiency and user experience. Massive MIMO is one of the promising techniques to
improve the spectral efficiency and network performance. Deploying massive number of antennas in 2D array colocated
at one base-station site is one way of massive MIMO deployment. 2D antenna array enables 3D beamforming
including both elevation domain and azimuth domain. This form of massive MIMO deployment has drawn tremendous
attention from the research community as well as the wireless industry. The 3rd Generation Partnership Project (3GPP),
a leading standard organization for mobile communication, has started the study on elevation beamforming and full
dimension (FD) MIMO. Various enhancement schemes have been studied. In the meantime, the industry has started
planning commercial use of the base station with large number of antennas in standard transparent manner. It would be
interesting to see how massive MIMO is realized in the field. Another way of massive MIMO deployment is distributed
deployment of massive number of antennas in a network comprising ubiquitous and dense antennas coordinated to form
a network-wide gigantic array. This ultra dense network architecture has drawn a lot of research interest recently. In
addition to the existing licensed cellular bands and unlicensed bands, the industry is looking for bands which can
provide ultra wideband communication. The mmWave band is one of the considerations for 5G network deployment.
This workshop aims to bring together leading researchers from both academia and industry to share their views on
massive MIMO and discuss the technical challenges after the recent advancements in massive MIMO.
