<p>A method and system for reducing the power consumption in a Time Division Duplex (TDD) system solves the problems of the high power consumption and the low efficiency of power amplifiers when the existing TDD system is in a fallback state. The method specifically comprises: a scheduling system calculating the number of symbols required in time domain according to the number of users in a cell; and determining a TDD time slot configuration and forwarding the TDD time slot configuration to a Remote Radio Unit (RRU) through a Base Band Unit (BBU). The system comprises: a calculation module, a configuration module and a forwarding module, wherein the calculation module is used for calculating the number of symbols required in time domain according to the number of users in a cell; the configuration module is used for determining the TDD time slot configuration according to the number of symbols required in time domain; and the forwarding module is used for forwarding the TDD time slot configuration to the BBU. With the present document, the working time of the power amplifiers is controlled by controlling the length of the time slots occupied by downlink, which not only satisfies the usage when the number of users is the maximum, but also works with the minimum power consumption when the number of users is zero or small.</p> |
