Modular base station
First Claim
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;

Abstract
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, and having antennas for receiving radio signals from mobile stations in a base station communication band, a communication interface for transferring data obtained via the received radio signals to the other base station modules and for receiving corresponding data from the other base station module, a data handling unit selects data for transfer to the other base station modules and an uplink data processing unit processes channels used by a subset of the mobile stations communicating with the base station, where the subset is assigned to the base station module. The base station module uses the data received from the other base station modules to influence processing in the uplink data processing unit.
