E-MIMO 2015 - International Workshop on Emerging MIMO Technologies with 2D Antenna Array for 4G LTE-Advanced and 5G (E-MIMO)

The wireless cellular network has been one of the most successful communications
technologies of the last three decades. The advent of smart phones and tablets over the
past several years has resulted in an explosive growth of data traffic over the cellular
network not seen in previous generations. In response to the increase in wireless data
traffic, the mobile industry has put much effort for providing cutting-edge techniques
to improve spectral efficiency and user experience. 3rd Generation Partnership Project
(3GPP), which is the leading standard forum for mobile communications, developed
multiple input multiple output (MIMO), carrier aggregation (CA), and coordinated
multi-point transmission/reception (CoMP) in LTE and LTE-Advanced standards. CA
simultaneously utilizes multiple carrier frequencies to enhance peak data rate and
network’s load balancing capability but requires the use of large frequency resource.
CoMP relies on coordination between multiple transmission and reception points to
enhance UE performance at cell edges but requires a very capable backhaul connection
for inter-site coordination. Although each of these techniques represents a major step
forward in improving system performance, further developments of new technologies
are required to meet an exponentially growing demand for wireless data traffic.
MIMO with large number of antennas placed in 2D array at the base station
transmitter called e.g. Full Dimension MIMO (FD-MIMO) or 3D MIMO has recently
been getting much attention as a promising technology to provide significant system
capacity improvement for the LTE-Advanced by utilizing 3D MIMO channel. Use of
2D antenna array would make it possible to utilize elevation domain in addition to
azimuth domain in beamforming operation. Large number of antenna elements would
improve the capability of shaping a narrow beam resulting in possibility of enhanced
multiuser MIMO operation.
As the fourth generation (4G), namely LTE-Advanced, becomes great commercial
success, the research community and mobile industry are now looking into future 5G
technologies. Among emerging technologies is to provide ultra wideband
communication at mmWave bands, in which 2D antenna array with large number of
antenna elements would play an important role to provide required coverage and
performance.
This workshop aims to bring together leading researchers in both academia and
industry to share their views on and to identify the emerging concepts and technologies
for MIMO with a large number of antennas in a path to 5G.
