Distributed Massive MIMO for Next Generation Wireless Communications

Obiettivo

In view of the rapid increase in demand for mobile data services, next generation wireless communication systems will have
to provide greatly increased capacity density and high data rates greater than 50Gbps. However, satisfying these
requirements for increasing numbers of users and connected devices, and increasingly bandwidth, processing power and
energy-hungry applications will require a transformation in the way in which current mobile and wireless networks perform.
Recently, massive multiple input multiple output (MIMO) technology, where each base station (BS) is equipped with a large
number of antenna elements (typically tens or even hundreds) has emerged as a key enabler to achieve a 1000 times data
rate and enormous spectral and energy efficiency. In order for massive MIMO to become a reality, the proposed work aims
to explore transformative methods for the design of innovative techniques in 3 key challenging areas of massive MIMO
communication systems: (i) fundamental limits; (ii), (ii) transmission strategy; and (iii) caching mechanisms. The solution is
achieved with small remote antenna units equipped with compact massive MIMO arrays deployed over certain coverage
regions, and developing practical signalling schemes, network coordination, and management protocols.
