System and method for minimizing signal interference between broadcasting signals and communication signals within local area and apparatus applied to the same

A method of minimizing interference between broadcasting signals and communication signals within a local area, the method performed by a local area wireless communication apparatus and comprising:

• multiplexing broadcasting signals corresponding to contents to be broadcasted through two or more radio frequency (RF) channels within a local area, wherein the broadcasting signals are unidirectional signals to one or more user terminal apparatuses;
• synchronizing two or more broadcasting frames of the broadcasting signals allocated onto the two or more RF channels on a time axis;
• transmitting the synchronized broadcasting frames for the broadcasting signals within the local area through the two or more RF channels;
• allocating, in response to a request for a communication service by the one or more user terminal apparatuses located in the local area, one bidirectional communication frame for communication signals onto one RF channel of the two or more RF channels after the broadcasting frames, wherein the broadcasting frames are unidirectional frames of the broadcasting signals, and the communication signals are bidirectional signals to and from the one or more user terminal apparatuses;
• allocating other bidirectional communication frames for the communication signals onto other RF channels of the two or more RF channels to thereby synchronize the allocated other bidirectional communication frames with the one bidirectional communication frame on the time axis;
• and
• communicating the communication signals with the one or more user terminal apparatuses located in the local area by using the synchronized one bidirectional communication frame and the allocated other bidirectional communication frames through the two or more RF channels.
