Query: Throughput Maximization in Cloud-Radio Access Networks using Rate-Aware
  Network Coding   One of the most promising techniques for network-wide interference management
necessitates a redesign of the network architecture known as cloud radio access
network (CRAN). The cloud is responsible for coordinating multiple Remote Radio
Heads (RRHs) and scheduling users to their radio resources blocks (RRBs). The
transmit frame of each RRH consists of several orthogonal RRBs each maintained
at a certain power level (PL). While previous works considered a vanilla
version in which each RRB can serve a single user, this paper proposes mixing
the flows of multiple users using instantly decodable network coding (IDNC). As
such, the total throughput is maximized. The joint user scheduling and power
adaptation problem is solved by designing, for each RRB, a subgraph in which
each vertex represents potential user-RRH associations, encoded files,
transmission rates, and PLs for one specific RRB. It is shown that the original
problem is equivalent to a maximum-weight clique problem over the union of all
subgraphs, called herein the CRAN-IDNCgraph. Extensive simulation results are
provided to attest the effectiveness of the proposed solution against state of
the art algorithms. In particular, the presented simulation results reveal that
the method achieves substantial performance gains for all system configurations
which collaborates the theoretical findings.
