Heterogeneous wireless networks have emerged as a new paradigm to meet the fast increasing wireless capacity and coverage demands. Cooperative communication is a promising technique to further improve the cell edge performance for future communication systems by allowing nodes in a communication network to collaborate with each other in information transmission. This paper presents an optimal intra-cell cooperative transmission in a relay based heterogeneous networks to best address both capacity and coverage demands. The authors first formulate the optimization problem to maximize the time averaged log-scale throughput.
