Abstract
A power control method, apparatus, and system is described. First outer loop power control is performed according to an actual hard metric and a preset target hard metric to adjust a target soft metric required by second outer loop power control, to obtain an adjusted target soft metric. Therefore, this ensures that when the adjusted target soft metric is converged, the target hard metric can be correctly converged to achieve target quality required by a system.
Claims20
A power control method comprising:
- acquiring an actual hard metric;
- and
- performing first outer loop power control according to the actual hard metric and a preset target hard metric to adjust a target soft metric, to obtain an adjusted target soft metric, wherein a second outer loop power control adjusts a target signal-to-interference ratio (SIR) according to an actual soft metric and the adjusted target soft metric.
A power control apparatus comprising:
- a receiver configured to acquire an actual hard metric;
- a processor;
- and
- a memory storing a program to be executed by the processor, the program comprising instructions for performing first outer loop power control according to the actual hard metric and a preset target hard metric to adjust a target soft metric, to obtain an adjusted target soft metric, wherein a second outer loop power control adjusts a target signal-to-interference ratio (SIR) according to an actual soft metric and the adjusted target soft metric.
