Abstract

A communication system and associated method are provided, wherein a quality of service is detected in the communication system, coordination reorganization is performed in order to reorganize coordination functionalities for available stations in the communication system, the previous two steps are repeated for various coordination organizations in the communication system, the various qualities of service detected in the various coordination organizations are analyzed, and a coordination organization is selected on the basis of this analysis, whereupon communication is affected with an external communication system which uses the same transmission medium as the communication system.

Claims

1. A communication system, comprising:

at least one base station;

at least one further station, wherein at least one of the base station and at least one of the further stations have a coordination changeover switch for changing over a coordination functionality between participating stations;

a quality-of-service detection apparatus for detecting a quality of service in the communication system; and

an analysis apparatus for analyzing the detected quality of service in the communication system, wherein the coordination changeover switch is controlled based on the analysis performed, and at least some of the further stations have an external transmission interface for implementing data transmission with an external communication system, the external communication system and the communication system being designed to use a common transmission medium.

2. A communication system as claimed in claim 1, wherein the quality-of-service detection apparatus and the analysis apparatus detect and analyze a transmission quality for transmission resources split in at least one of a space domain, a time domain, a domain frequency and a domain of code.

3. A method for improving a quality of service in a communication system, the method comprising the steps of:

detecting a quality of service in a communication system;

performing coordination reorganization to reorganize coordination functionalities for available stations in the communication system;

repeating the steps of detecting and performing for various coordination organizations in the communication system;

analyzing various qualities of service detected in the various coordination organizations; and

selecting a coordination organization based on the step of analyzing, whereupon communication is effected with an external communication system which uses a same transmission medium as the communication system.

4. A method for improving a quality of service in a communication system as claimed in claim 3, wherein the step of selecting a coordination organization is based on a quality of service which is one of best and worst.

5. A method for improving a quality of service in a communication system as claimed in claim 3, wherein the quality of service is a transmission quality for transmission resources in at least one of a time domain, a frequency domain, a code domain and a space domain of a jointly used transmission medium.

6. A method for improving a quality of service in a communication system as claimed in claim 3, wherein selection of the coordination organization is based on setting a coordination functionality for at least one of a time domain, a frequency domain, a code domain and a space domain for available stations.
