Abstract:
This paper studies downlink resource reuse schemes
for cellular networks with coexisting femtocells and macrocells.
We examine two reuse schemes, termed split reuse and shared
reuse. In this paper, we develop an analytical model of resource
allocation based on random graphs. In our model, arbitrarily
chosen communication links interfere with each other with a
certain probability, which depends upon whether the links belong
to femtocell or macrocell users. Using this model, we establish
asymptotic bounds on the minimum number of resource blocks
required to make an interference-free resource assignment for
all the users in the network for large numbers of users. We
assess these bounds using a simple greedy resource allocation
algorithm to demonstrate that the bounds are reasonable in ?nite
networks of plausible size. By applying the bounds, we establish
the expected impact of femtocell networks on macrocell resource
allocation under a wide variety of interference scenarios. Further,
we assess the ef?ciency loss associated with split reuse, as an
aid to determining whether resource allocators should use the
simpler split reuse scheme or attempt to tackle the complexity
and overhead associated with shared reuse.
