Abstract

A multi-coexistence communication technology is provided. A multi-coexistence communication system based on an interference-aware environment and a method for operating the same can remove interference detected using an interference temperature limit from at least one transmission signal and transmit the signal to a main/sub communication terminal during data communication on a wired/wireless communication network formed of a main base station, a sub base station, the main communication terminal, and the sub communication terminal, thereby smoothly providing a high-speed seamless data transmission service based on a multi-coexistence communication environment where a distributed small-scale network requiring a low transmission rate, a medium-scale network for providing various wireless communication services, and a large-scale broadcasting network requiring a high transmission rate and high quality coexist, and preventing congestion due to increased demand for frequency resources.

Dependent claims

A multi-coexistence communication system comprising:

a main base station generating a main transmission signal;
a sub base station receiving the main transmission signal from the main base station;
a main communication terminal;
and
a sub communication terminal, wherein:
the main base station, the sub base station, the main communication terminal and the sub communication terminal coexist on a wired/wireless communication network;
the sub base station independently generates a sub transmission signal and allocates a frequency bandwidth of the sub communication terminal within a frequency use capacity range after setting frequency use capacity by receiving a preset frequency bandwidth and an interference temperature limit from the main communication terminal;
the main communication terminal receives a true main transmission signal reconfigured by removing a sub transmission signal value determined as an interference factor of the main transmission signal from the sub base station;
the sub communication terminal receives a true sub transmission signal reconfigured by removing a main transmission signal value determined as an interference factor of the sub transmission signal from the sub base station;
and
the sub base station divides preset transmit power into partial transmit power and remaining transmit power excluding the partial transmit power and simultaneously transmits the true main transmission signal at the partial transmit power and the true sub transmission signal at the remaining transmit power.
