A METHOD OF CONTROLLING POWER IN A WCDMA SYSTEM

摘要

A method and a device relating to a scheduling mechanism in a base statio n in a WCDMA system are disclosed. The mechanism enables the base station to rapidly adapt to users momentary traffic demands and to interference variat ions, a dynamical adjustable margin is proposed in this invention. The adjus tment is based on the RoT measurement in a cell. To fully use the resource i n a cell, the RoT can be targeted to be as closer to the RoTmax as possible however without exceed the limit. The scheduler is preferably set to schedul e as high a rate or as many users as possible to fill up the available RoT. The margin which is reserved for the neighboring cell load and external inte rference is decreased step by step as long as the RoT measurement is below a threshold under RoTmax. Whenever the RoT measurement exceeds the threshold, the margin is increased by one step.
