Abstract
The present invention relates to a method and an arrangement for channel allocation in a radio communication system in which data is transmitted between two stations over two or more radio channels. Data is communicated as packets which are divided into blocks while the transmission follows a protocol for automatic re-transmission of data that have been erroneously transmitted. In accordance with the proposed method, channels for re-transmission are allocated with respect to a transmission parameter which has been created at a previous transmission and which is based upon information of the result of said previous transmission. The transmission parameter is aimed to ensure that re-transmission is performed via those channels which have the highest probability of transmitting data correctly. The channels which had the highest transmission quality in said previous transmission are expected to have the highest transmission quality also by re-transmission.
