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： A radio network system employing a method with dynamic adjustment of the power offset that provides a “per-UE”-NACK to ACK power offset calculation method instead of using a fixed offset for all users in the cell is disclosed. Also for each UE, the power offset can adjusted dynamically. The adjustment is based on the error event of NACK to ACK. When an error event of NACK to ACK happens, the offset is increased, otherwise the offset is decreased. Hence, the offset can be controlled for each User Equipment for the duration of a call starting from some standard configured value is calculated and used rather than a fixed offset.
摘要翻译：公开了一种使用动态调整功率偏移的方法的无线电网络系统，该方法为ACK功率偏移计算方法提供“每UE”-NACK，而不是对小区中的所有用户使用固定偏移。同样对于每个UE，功率偏移可以动态调整。调整是基于NACK到ACK的错误事件。当发生NACK到ACK的错误事件时，偏移增加，否则偏移减小。因此，在从一些标准配置值开始的呼叫期间，可以为每个用户设备控制偏移量，而不是固定偏移。

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.

摘要： A method, system and apparatus for spreading physical channels using partly orthogonal multiple code trees. A portion of a first code tree is used to spread the physical channels. This first code tree is a combination of a channelization code sequence and a first scrambling code sequence. A portion of a second code tree is used to spread the physical channels that are remaining and were not spread using the first code tree. This second code tree is a combination of the channelization code sequence and a second scrambling code formed by modifying the first scrambling code. The portion of the second code tree used to spread the channels is orthogonal to the portion of the first code tree used. A plurality of other code trees could be formed using scrambling codes based on the modification of the first scrambling code.
