Document Type and Number:
Japanese Patent JP2017085508
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To give an impartial transmission opportunity to a plurality of radio communication terminals.SOLUTION: A radio communication system in one aspect of the present invention comprises a first radio communication terminal and a second radio communication terminal. The first radio communication terminal includes a first control unit which transmits a first frame including information to designate a plurality of frequency components. The second radio communication terminal includes a second control unit which receives the first frame, to determine response capability or incapability according to a first value, which is an arbitrary value selected from a first range, and the number of the frequency components which are designated by the first frame, and when determining to respond, transmits a second frame using a frequency component selected from the plurality of frequency components. According to whether the transmission of the second frame is successful, the second control unit adjusts the magnitude of the first range.SELECTED DRAWING: Figure 15
