Power determination method and base station

Abstract

The invention provides a power determination method and a base station. The power determination method includes taking the fact that throughput of each user is not smaller than a throughput threshold value as an optimization condition, taking minimization of the total power consumption as an optimization target, optimizing quantity of subcarriers occupied by each user, quantity of started radiofrequency links of the base station and transmission power of the base station to acquire the optimum quantity of subcarriers of each user, the optimum quantity of started radiofrequency links of the base station and the optimum transmission power of the base station; then determining the total power consumption of the base station according to the optimum quantity of subcarriers of each user, the optimum quantity of started radiofrequency links of the base station and the optimum transmission power of the base station. By the power determination method in the technical scheme, the total power consumption of the base station in a downlink MIMO-OFDM (multiple input multiple output-orthogonal frequency division multiplexing) system can be minimized, and power consumption of the downlink MIMO-OFDM can be reduced.
