  Internet of things is in progress to build a smart society, and wireless
networks are critical enablers for many of its use cases. In this paper, we
present a multi-coordinated transmission scheme to achieve ultra-reliability
for critical machine-type wireless communication networks. We take advantage of
diversity, which is fundamental for dealing with fading channel impairments,
and for achieving ultra-reliable region of operation in order of five 9's as
defined by 3GPP standardization bodies. We evaluate an interference-limited
network composed of multiple remote radio heads that are allowed to cooperate,
by keeping silence thus reducing interference, or by performing more elaborated
strategies such as maximal ratio transmission, in order to serve a user
equipment with ultra-reliability. We provide extensive numerical analysis and
discuss the gains of cooperation by the centralized radio access network.
