摘要： The present invention is directed to a method and a node arrangement for extending the cell range in a wireless communication system, which communication system comprises a communication network arranged to operatively communicate with at least one mobile terminal via an air interface having a cell range extending to a cell edge, and at least one mobile terminal arranged to operatively communicate with said communication network via said air interface. The method comprises the steps of: obtaining information about the condition of an up-link signal from said at least one mobile terminal; determining whether said terminal is located at or near the cell edge, and extending the cell range by increasing the time for up-link transmission if the terminal is located at or near the cell edge.

摘要： A method of adapting resource allocation parameters to reach one or more quality targets with improved accuracy is proposed. New information measurements based on the so-called mutual information, preferably at block-level, are introduced. The MI-based information measurements of a previous transmission, the channel prediction of a subsequent transmission and one or more quality requirements, are used to determine the amount and type of resources, e.g. time, frequency and power resources, that are to be used for the subsequent transmission. The resource allocation can for example comprise power allocation and/or link adaptation and the invention enables an advantageous implementation with cooperative link-adaptation and power allocation. The proposed method is useful in connection with ARQ/HARQ retransmissions.
