Abstract:
1. A method of interference mitigation in a multi user detection capable radio base station in a communication system, said radio base station being modularly arranged and comprising a set of confined detection modules, at least one of which is capable of handling multiple user connections, comprising: forming a first subset of detection modules within said radio base station from said set; forming at least a second subset of detection modules within said radio base station from said set, said second set comprising at least one interference mitigation capable detection module; wherein each of the confined detection modules has one or more distinct user connections assigned to it; communicating interference information concerning the respective user connections of said first subset from said first subset to said second subset, and wherein said first subset and said second subset are configured to only allow communication of information in one direction; mitigating interference originating in said user connections of said first subset from the user connections of said second subset; mutually mitigating interference between the connections or a subset of connections within said at least one interference cancellation capable detection module; and decoding all users within said at least one interference cancellation capable detection module.
