Method and arrangement for interference mitigation

摘要

In a method of interference mitigation in a multi user detection capable radio base station in a communication system, which radio base station comprises a set of confined detection modules, at least one of which is capable of handling multiple user connections, first and at least a second subset of detection modules are formed from said set, wherein the second set comprises at least one interference mitigation capable detection module. Interference information from the first subset is communicated to the second subset, interference originating in user connections of the first subset are then mitigated from the user connections of the second subset. Subsequently, interference is mutually mitigated between the connections within the interference mitigation capable detection module.

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:
allocating user connections to the set of detection modules based on service; 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; mitigating interference originating in said user connections of said first subset from the user connections of said second subset; and mutually mitigating interference between the connections or a subset of connections within said at least one interference cancellation capable detection module.
