摘要： The present invention discloses a method for solving non-controllability of terminal's power spectrum density in OFDMA system. It considers the problem of non-controllability of terminal's carrier transmit power resulting from the indeterminacy of carrier number allocation to the terminal in the OFDMA system which is solved by introducing the maximum carrier number that can be allocated to the terminal by combing AMC, the power control and the dispatching. By applying the present invention, the carrier power of the terminal can be best controlled by the system, it is most possible for the terminal to transmit power on carrier completely according to a set value, while it is greatly reduced the possibility that the terminal's power spectrum density is suddenly decreased out of control, which is caused by the summation of carrier powers in the set value exceeding the maximum total transmit power. Moreover, it is avoided occurrence of a large amount of error codes in that condition and the waste of power resources resulting from the excessive restriction on the carrier power.

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.
