Method for improving reverse gain

A method for improving reverse gain, the method being applied in an Orthogonal Frequency Division Multiple Access system, comprising:

• step A, determining by a base station whether a reverse reception performance demand can be met without a reverse repetition,
• if said determining step determines that the reverse reception performance demand cannot be met without a reverse repetition then executing step B without changing a service quality requirement and a transmission speed of a terminal;
• and
• step B, further determining by the base station whether the reverse gain can be improved using the reverse repetition,
• if the base station determines in said further determining step that the reverse gain still cannot be improved by the reverse repetition then notifying the terminal by the base station not to enable the reverse repetition;
• otherwise, notifying the terminal by the base station to enable the reverse repetition.
