With the continuous improvement of the transmission rate and the quality of wireless communications services, the need for a wireless communication network structure to adjust. The traditional rules of cellular networks no longer meet the high-density, large number of people for high-speed data transmission. Heterogeneous network can solve the problem of network coverage and network-efficient transport, but because of the heterogeneous network dense arrangement of the network, so the introduction of a number of inter-cell interference, especially at the edge of the cell. To solve this problem, we use collaborative tools of game theory, to be distributed among the power cells to determine the coverage of each pico cell. But the need to optimize collaboration between cells, select the number and scope of the coordinated cell. Simulation results show that the proposed algorithm can effectively improve the transmission rate of the system, eliminating the interference between cells.
