摘要： The present invention provides a scheduler capable of maximizing aggregate throughput while achieving controlled amount of fairness among users and meeting Quality of Service (QoS) requirements. The scheduler is configured to select the next unit of data to transmit from multiple queues associated with access terminals waiting to receive the data. For each access terminal, a weighting factor is calculated based on a temporal fading factor, a throughput fairness factor, and a delay QoS factor. The unit selected for transmission corresponds to the access terminal having the greatest overall weighting factor. The process repeats for each unit being transmitted.

摘要翻译： 本发明提供一种调度器，其能够最大化聚合吞吐量，同时在用户之间达到受控的公平的量并且满足服务质量（QoS）要求。 调度器被配置为从等待接收数据的接入终端相关联的多个队列中选择要发送的下一个数据单元。 对于每个接入终端，基于时间衰落因子，吞吐量公平因子和延迟QoS因子来计算加权因子。 选择发送的单元对应于具有最大总权重因子的接入终端。 对于正在发送的每个单元，该过程重复。

摘要： One of a plurality of base stations is selected by a network entity, such as a mobile control point, for communicating with a respective remote station. Transmission channel quality information associated with at least two of the base stations is received at predefined intervals. Loading information associated with the base stations is received at further predefined intervals. A respective one of the base stations is selected as a function of the quality information and the loading information. An indication that the respective remote station is to commence communication with the selected one of the at least two base stations is sent to the respective remote station.
