Coordinated digital radio distribution architecture

摘要

A communication system architecture is provided, having an aggregator, arranged to centralize the access units and coordinate the radio signals of access units of different types digitally, and remote radio units configured to be modularly connectable to different types of radio elements that correspond to the access units and arranged to communicate with the aggregator digitally. Radio signals are scheduled and delivered with respect to the types of the access units and of the radio elements, and the aggregator is further arranged to handle distribution and combining of the radio signals digitally. The aggregator further comprises a controller arranged to continuously optimize communication with respect to the access units and user mobile communication devices by applying a decision process to cost functions that depends on communication parameters to derive specified dynamically changing parameters, and to manage the aggregator dynamically with respect thereto.

1. A coordination system for coordinating radio signals in a communication system comprising a first plurality of access units and a second plurality of remote units, the coordination system comprising:
a management system; and an aggregator arranged to coordinate the radio signals between the access units and the remote units, the aggregator comprising:
a first plurality of access front end modules, each in radio signal communication with a corresponding access unit;a second plurality of remote unit front ends, each in radio signal communication with a corresponding remote unit;a first plurality of access processing and analyzing units, each in communication with a corresponding access front end module and comprising:
a signal analysis unit arranged to derive communication parameters of the communication system;a combiner arranged to provide uplink radio signals to the access front end module; anda distributor arranged to provide downlink radio signals from the access front end module,a bi-directional baseband router module arranged to deliver the uplink radio signals from the remote unit front ends to the combiners and to deliver the downlink radio signals from the distributors to the remote unit front ends according to specified dynamically changing parameters; anda processor unit arranged to continuously determine the specified dynamically changing parameters by applying a decision process to at least one cost function that depends on the communication parameters in respect to instructions from the management system.
