摘要： 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.
摘要翻译：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。

摘要： A load control method is described herein that enables a base station to broadcast three downlink signals including a busy indicator, a maximum resource indicator and a minimum resource indicator to a mobile terminal. In response to receiving the downlink signals, the mobile terminal limits the utilization of a resource (e.g., bit rate, transmission power, power offset) it uses to transmit data to the base station. The mobile terminal may also send an uplink signal including a resource request to the base station. The base station can use the resource request to change the downlink signals if needed. It is with the proper use of these uplink/downlink signals that the behavior of the base station can be automatically optimized to the load situation.

摘要： In a cellular telecommunications system, a method of dynamically allocating packet data radio channels among users competing in a same cell for the channels involves determining a user ranking for each of plural competing users in the cell, and classifying each of the plural competing users into one of plural ranking classes. A number of the packet data radio channels available for each of the ranking classes is then determined, after which the users within each ranking class are sorted by ranking. The packet data radio channels are allocated to the users by sorted position within ranking classes. The user ranking for each of the plural competing users in the cell is related to a weighted combination of plural measures of performance for the user.

摘要： An interference analysis tool for identifying an interference problem area in a cellular radio network in which at least a first User Equipment (UE1) and a second UE (UE2) operate. The tool receives signal quality measurements and determines uplink or downlink interference severity. For UE2 uplink interference, the tool determines a first uplink Signal-to-Interference-and-Noise-Ratio (SINR) experienced by UE2, wherein the first SINR includes uplink interference from UE1. The tool also determines a second uplink SINR level (SINR0) experienced by UE2, wherein SINR0 does not include the uplink interference from UE1. The tool calculates a difference (ΔSINR) between SINR and SINR0 for UE2, and identifies the area where UE1 is operating as an interference-causing area when the ΔSINR for UE2 is greater than a threshold value. The tool may present interference severity levels to an operator, and may initiate Radio Resource Management (RRM) procedures to mitigate interference problems in the network.

摘要： A cellular radio communication system includes a first serving cell and a second non-serving cell. A mobile radio is currently served by a first base station in the first cell. An uplink radio transmission from the mobile radio will cause or causes inter-cell interference in the second non-serving cell. Accordingly, an estimate is made of the inter-cell interference in the second non-serving cell associated with the mobile radio's uplink transmission. If the estimated inter-cell interference in the second non-serving cell exceeds a predetermined threshold, then control is performed so that the inter-cell interference in the second non-serving cell is limited, e.g., by managing radio resources so that the estimated inter-cell interference in the second non-serving cell is or becomes less than the predetermined threshold.
