2019 IEEE International Conference on Communications Workshops (ICC Workshops): Workshop on User-Centric Cell-Free Ultra-Dense Massive MIMO Networks (CF-MIMO)

Driven by the development of mobile Internet and smart phones, data traffic grows exponentially in current mobile communication systems. Massive multiple-input multiple-output (MIMO) is an exciting area of 5G wireless research to enable extraordinary gains in capacity and energy efficiency. The Massive MIMO technology can bring at least ten-fold improvements in area throughput by increasing the spectral efficiency (bit/s/Hz/cell), while using the same bandwidth and density of base stations as in current networks. Recently, a new concept for cell-free network architecture based on Massive MIMO has been proposed as Cell-Free Massive MIMO, a network deployment with no cells. All service antennas my possibly coherently serve all user terminals; the time-division-duplex protocol is used for exploitation of uplink/downlink channel reciprocity, and channel coefficients are estimated locally at each access point and are not sent on the backhaul. User-centric, cell-free massive MIMO systems have been shown to have the potentiality of greatly alleviating the cell-edge problem, enabling good quality of service to the vast majority of the users in the system.
Also, initial estimations indicate that, different from the evolutionary path of previous cellular generations that was based on spectral efficiency improvements, the most substantial amount of future system performance gains will be obtained by means of network infrastructure densification. Ultra dense network (UDN) deployment in combination with cell-free massive MIMO concept is a promising technique to meet the requirements of explosive data traffic in 5G mobile communications.
This workshop will bring together academic and industrial researchers to identify and discuss technical challenges and recent results related to the User-Centric Cell-Free Massive MIMO and their ultra delse deployment for future mobile networks.
