  This paper proposes interference mitigation techniques for provisioning
ultrareliable low-latency wireless communication in an industrial automation
setting, where multiple transmissions from controllers to actuators interfere
with each other. Channel fading and interference are key impairments in
wireless communication. This paper leverages the recently proposed ``Occupy
CoW'' protocol that efficiently exploits the broadcast opportunity and spatial
diversity through a two-hop cooperative communication strategy among
distributed receivers to combat deep fading, but points out that because this
protocol avoids interference by frequency division orthogonal transmission, it
is not scalable in terms of bandwidth required for achieving ultrareliability,
when multiple controllers simultaneously communicate with multiple actuators
(akin to the downlink of a multicell network). The main observation of this
paper is that full frequency reuse in the first phase, together with successive
decoding and cancellation of interference, can improve the performance of this
strategy notably. We propose two protocols depending on whether interference
cancellation or avoidance is implemented in the second phase, and show that
both outperform Occupy CoW in terms of the required bandwidth and power for
achieving ultrareliability at practical values of the transmit power.
