1. A base station module configured to be part of a group of base station modules comprising the base station module and other base station modules, the group of base station modules together forming a base station, said base station module comprising:

  • at least one antenna for receiving radio signals from mobile stations in a base station communication band comprising a number of channels;

    a first communication interface for transferring data obtained via said received radio signals to the other base station modules and for receiving corresponding data obtained via radio signals received by the other base station modules;

    a data handling unit in a processor of the base station module configured to select data for transfer to the other base station modules;

    an uplink data processing unit in a processor of the base station module configured to process channels used by a subset of mobile stations of a set of mobile stations communicating with the base station, said subset being assigned to the base station module, where said base station module is configured to use said data received from the other base station modules to influence processing in the uplink data processing unit in the processor;

    a transforming unit configured to transform the radio signals from the time domain to the frequency domain and the first communication interface is provided for communicating frequency domain signals;

    a downlink data processing unit in a processor of the base station module configured to code data to be sent in radio signals to said assigned subset of mobile stations in corresponding channels and a second communication interface configured to receive data from the other base station modules concerning the mobile stations in subsets assigned to the other base station modules and transmit data of the mobile stations in the assigned subset to the other base station modules, wherein the data received via the second communication interface are radio signals with data concerning mobile stations outside of the assigned subset;

    at least one transmitting antenna via which the data of the whole set of mobile stations is transmitted to the other modules for transmission; and

    a multiplexing unit connected to the downlink data processing unit in the processor and the second communication interface for receiving coded and modulated signals with data concerning all mobile stations and being configured to combine them to at least one radio signal for transmission over said at least one antenna.
