Abstract: A communication device includes an calculation unit, a measuring unit, a setting unit, and a determination unit. The calculation unit calculates an index value according to each of the other communication devices for determining whether to let a wireless resource utilized for communications with the other communication device be a candidate allocated to the other communication device based on the quality of a channel to the other communication device. The measuring unit measures a congestion degree between itself and the other communication device. The setting unit calculates a threshold value for determining whether to let the wireless resource be the candidate allocated to the other communication device based on the measured congestion degree. The determination unit compares the index value with the threshold value to determine whether to let the wireless resource be the candidate allocated to the other communication device.

Abstract: A communication device in wireless communication with another communication device or devices includes an index value calculation unit, a congestion degree measuring unit, a threshold value setting unit, and a determination unit. The index value calculation unit calculates an index value according to each of the other communication devices for determining whether or not to let a wireless resource utilized for communications with the other communication device be a candidate allocated to the other communication device based on the quality of a channel to the other communication device. The congestion degree measuring unit measures a congestion degree between itself and the other communication device. The threshold value setting unit calculates a threshold value for determining whether or not to let the wireless resource be the candidate allocated to the other communication device based on the measured congestion degree.
