摘要： A method for improving reverse coverage is disclosed, comprising: A, when a base station requests a terminal to enable the reverse repetition, under the condition that the service quality requirement and the transmission speed of the terminal are persistent, then step B is executed; B, if the reverse gain still cannot be improved after repetition, the reverse repetition will not be enabled; or, the reverse repetition will be enabled. The method of the present invention can take account of subchannelization gain, repetition gain and the interaction of both as an integration, to ensure that the whole gain of reverse link increases after the enabled repetition, and to prevent the system from sacrificing the bandwidth without improving but deteriorating the reverse coverage capability in certain circumstances after the enabled repetition occurs.
