Title: COMMUNICATION DEVICE AND COMMUNICATION METHOD
Abstract:
Provided are a communication device and a communication method in which a space is reused between adjacent cells. A terminal performing SR transmission using information obtainable from an adjacent cell signal adjusts an SR backoff time by information such as the magnitude of the interference power received by the terminal itself and the distance to an AP and thereby seizes a transmission opportunity while avoiding a packet collision. A terminal having succeeded in SR transmission is subject to a penalty of setting an additional backoff time. Meanwhile, the AP sets, to an STA, a parameter for transmission wait time adjustment that corresponds to the number of units, throughput situation, or the like of subordinate terminals.
