Query: Opportunistic Scheduling of Machine Type Communications as Underlay to
  Cellular Networks   In this paper we present a simple method to exploit the diversity of
interference in heterogenous wireless communication systems with large number
of machine-type-devices (MTD). We consider a system with a
machine-type-aggregator (MTA) as underlay to cellular network with a multi
antenna base station (BS). Cellular users share uplink radio resources with
MTDs. Handling the interference from MTDs on the BS is the focus of this
article. Our method takes advantage of received interference diversity on BS at
each time on each resource block and allocates the radio resources to the MTD
with the minimum interference on the BS. In this method, BS does not need to
take the interference from MTD into account in the design of the receive
beamformer for uplink cellular user, hence, the degrees of freedom is not used
for interference management. Our simulation results show that each resource
block can be shared between a cellular user and an MTD, with almost no harmful
interference on the cellular user.
