Coordinated multi-point (CoMP) has evolved as a
performance-optimizing technique for cellular networks. In this
paper, we investigate two different spectrum allocation schemes
for CoMP (i.e., shared and dedicated) within the context of
Remote Radio Head (RRH) enabled heterogeneous network
(HetNet) topology. The traditional macro cell only layout serves
as baseline. Using spectral efficiency and average user throughput
as system level performance metrics, our results reveal that
CoMP based on shared spectrum outperforms the other two.
The scheme, therefore, has great potential for optimizing radio
resources and boosting the performance of next-generation mobile
networks.
