METHOD, DEVICE AND BASE STATION FOR ALLOCATING POWER

摘要

A method, a device and a base station for allocating power, which can provide optimal energy efficiency for a system, are disclosed in the embodiments of the present invention, wherein the method includes: when total transmitting power Pt is a fixed value, computing a proportion a of reference signal power to the fixed value and a proportion ßm of user data power of a user Um to the fixed value, wherein the user Um is any user in connection state in the system; according to the proportion a and proportion ßm, judging whether the energy efficiency of the system is maximum when the total transmitting power Pt is the fixed value; if yes, obtaining the proportion a and proportion ßm, otherwise, updating the total transmitting power Pt; computing the proportion a and proportion ßm after the total transmitting power Pt is updated, and judging whether the energy efficiency of the system is maximum after the total transmitting power Pt is updated; if yes, obtaining the computed proportion a and proportion ßm after the total transmitting power Pt is updated. The method provided in the present invention can further reduce system power consumption based on optimizing total power, reduce total energy consumption of the air interface of the system greatly, and realize efficient power saving.
