Abstract:
The present invention provides a method and a base station for power determination. The method comprises obtaining an optimal number of sub-carriers occupied by each user equipment, an optimal number of radio frequency links enabled by a base station and an optimal transmitting power of the base station by optimizing the number of the sub-carriers occupied by each user equipment, the number of the radio frequency links enabled by the base station and the transmitting power of the base station with an optimization condition that throughput of each user equipment is not smaller than a throughput threshold and an optimization goal of minimizing total power consumption of the base station; and determining the total power consumption of the base station according to the optimal number of the sub-carriers occupied by each user equipment, the optimal number of the radio frequency links enabled by the base station.
Abstract:
Embodiments of the present invention disclose a precoding method and an apparatus for heterogeneous network coordinated multi-point transmission. The method includes the following steps: obtaining parameter information of the heterogeneous network coordinated multi-point transmission system; comparing a first channel space transmitting power with the maximum transmitting power of a macro base station, and comparing a second channel space transmitting power with the maximum transmitting power of a micro base station according to the parameter information to obtain a comparison result; determining an obtaining manner of a precoding vector according to the comparison result, and obtaining a first precoding vector according to the obtaining manner of the precoding vector; and configuring the macro base station and the micro base station according to the first precoding vector. The present invention is applicable to a heterogeneous network coordinated multi-point transmission environment.
