Method and device for performing communication in wireless communication system

A method of performing communication by a receiver in a wireless communication system, the method comprising:

• performing communication by using a first communication scheme during a first time interval;
• receiving, from a transmitter, information on a second time interval having a duration determined according to a communication state during the first time interval;
• and
• performing communication by using the first communication scheme during the second time interval according to the received information on the second time interval,
• wherein the first time interval and the second time interval are included in a frame allocated for a second communication scheme that is different from the first communication scheme,
• wherein a frequency used for the first communication scheme is identical to a frequency used for the second communication scheme, and
• wherein a signal transmission operation of second devices using the second communication scheme is suspended during the first time interval and the second time interval.

A transmitter in a wireless communication system, the transmitter comprising:

• a controller configured to determine a communication state for first devices using a first communication scheme during a first time interval, and to determine a duration of a second time interval to be allocated for the first devices according to the communication state;
• and
• a communication unit configured to transmit information on the second time interval having the determined duration to the first devices before the second time interval starts,
• wherein the first time interval and the second time interval are contained in a frame allocated for a second communication scheme that is different from the first communication scheme,
• wherein a frequency used for the first communication scheme is identical to a frequency used for the second communication scheme, and
• wherein a signal transmission operation of second devices using the second communication scheme is suspended during the first time interval and the second time interval.
