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 dividing a subcarrier permutation zone in an Orthogonal Frequency Division Multiple Access system and an information configuration system for dividing a subcarrier permutation zone in the Orthogonal Frequency Division Multiple Access system are disclosed in the present invention. Wherein, the method for dividing the subcarrier permutation zone includes the following steps: a configuration unit performing configuration to a subcarrier permutation zone division information, and sending the subcarrier permutation zone division information to a configuration synchronization unit; the configuration synchronization unit calculating a configuration effective frame number, and sending the subcarrier permutation zone division information and the configuration effective frame number to a base station; the base station dividing the subcarrier permutation zone according to the subcarrier permutation zone division information and the configuration effective frame number. With the present invention, it can uniformly configure, in the whole network, the frame in which the subcarrier permutation zone appears and the position in the frame, so as to avoid the co-frequency interference between each of the adjacent zones.
