The present invention is suitable for heterogeneous networks. Provided are a base station-discontinuous transmission (BS-DTX) energy-saving control method, macro cell, micro cell and heterogeneous networks. On the micro cell side, the method comprising: at the beginning of each control period, the micro cell acquires a total cost required for serving the associated user thereof, and feeds the total cost back to the macro cell; receiving a control instruction corresponding to a preferred control policy transmitted by the macro cell so as to correspondingly enable or disable the micro cell. On the macro cell side, the method comprises: receiving the total cost from each micro cell, acquiring the total cost of the entire network under different control policies according to the total cost, and utilizing the control policy corresponding to the minimum total cost of the entire network as the preferred control policy; and transmitting the control instruction corresponding to the preferred control policy to the micro cell. The present invention considers the impact of the channel condition on network power consumption, such that the macro cell obtains a preferred control policy, thus further reducing system energy consumption while satisfying a time delay requirement. |
