Abstract

A coordination method between access points using unlicensed frequency bands and a network control node using this method are disclosed. The method includes: the first access points adjusting transmission parameters thereof to increase channel access probability of the first access points; and the second access points adjusting transmission parameters thereof to decrease the channel access probability of the second access points; wherein the degree to which channel access probability of the third access points is decreased due to adjustment of the transmission parameters of all the first access points is equivalent to the degree to which the channel access probability is increased due to adjustment of the transmission parameters of all the second access points. Through coordination between multiple access points in the same network, fair coexistence with other networks using unlicensed frequency bands can be ensured while user QoS is improved.
