User scheduling and power control collaboration method for LTE-A heterogeneous network

The invention discloses a user scheduling and power control collaboration method for an LTE-A heterogeneous network. The method comprises the following steps: step 1, collecting channel state information; step 2, initializing iterative parameters; step 3, calculating optimal transmitting power of each user; step 4, selecting resource blocks and scheduling users; step 5, updating the iterative parameters; step 6, judging whether a stop condition is satisfied, and if not, returning to step 3; and step 7, outputting a result. By adoption of the method provided by the invention, the minimum number of the resource blocks RB for interference collaboration at low transmitting power can be realized, the method has the advantages of being fast and efficient, and can well meet the requirements of the 4G LTE-A mobile communication network for reducing the cross layer interference. 本发明公开了用于LTE-A异构网络的用户调度与功率控制协同方法，包括以下步骤：步骤1，采集信道状态信息；步骤2，初始化迭代参数；步骤3，计算每个用户的最优发送功率；步骤4，选择资源块及调度用户；步骤5，更新迭代参数；步骤6，判断是否满足停止条件，若不满足，返回步骤3；步骤7，输出结
