Abstract
In a method of assigning an idle channel in which a base station assigns an idle channel in response to a link channel establishment request from a mobile terminal, a criterion level for judging whether an idle channel is to be used or not is set to an appropriate level which is higher than a limit level of a ratio of an interference level to a detectable signal receiving level (a DU ratio). In response to a link channel establishment request from a mobile terminal, the base station performs carrier sensing operation to obtain all idle channels and signal receiving levels of the idle channels, selects an idle channel having a level which exceeds the set criterion level and is closest to the criterion level, and assigns the selected idle channel as a link channel.
