    • A method and a device relating to a scheduling mechanism in a base station in a WCDMA system are disclosed. The mechanism enables the base station to rapidly adapt to users momentary traffic demands and to interference variations, a dynamical adjustable margin is proposed in this invention. The adjustment is based on the RoT measurement in a cell. To fully use the resource in 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 schedule 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 interference 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.
    • 公开了一种与WCDMA系统中的基站中的调度机制相关的方法和装置。 该机制使基站快速适应用户瞬时业务需求和干扰变化,本发明提出了动态可调边距。 调整是基于单元格中的RoT测量。 为了充分利用单元格中的资源,RoT可以被定向为尽可能接近RoTmax,但不超过极限。 调度器优选地被设置为调度尽可能高的速率或尽可能多的用户来填充可用的RoT。 只要RoT测量值低于RoTmax的阈值,保留给邻近小区负载和外部干扰的余量就会逐步降低。 每当RoT测量超过阈值时,边距增加一步。
