Claim of US Patent No. 10,602,544

1. A method of determining a carrier sense threshold by a source terminal in a wireless communication system, the method comprising:identifying whether two or more interferer terminals and two or more destination terminals exist for the source terminal;
receiving two or more interference intensity values from the two or more interferer terminals;
receiving one or more feedback link margin values from the two or more destination terminals;
obtaining a plurality of first carrier sense thresholds corresponding respectively to a plurality of combinations between each of the two or more interferer terminals and each of the two or more destination terminals, based on the two or more interference intensity values and the one or more feedback link margin values; and
adjusting transmission power of the source terminal based on the plurality of first carrier sense thresholds,
wherein the plurality of first carrier sense thresholds are different from each other.
