The wireless communication apparatus and wireless communication method

The invention discloses a wireless communication device and a wireless communication method. The wireless communication device is communicated with another wireless communication device by a wireless frame. The device comprises an avoidance frequency acquisition unit, a comparison unit, a storage unit, a state index adjustment unit, a sending unit, a receiving unit, a subtractor and a competitiveaccess adjustment unit, wherein the avoidance frequency acquisition unit acquires the avoidance frequency subjected to competitive access when the wireless communication device is communicated with another wireless communication device according to the wireless frame with a first fame length; the comparison unit compares the avoidance frequency with a threshold value; the storage unit stores delay indexes; the state index adjustment unit increases the stored state indexes when the avoidance frequency is greater than the threshold value; the sending unit sends the increased state indexes to another wireless communication device; the receiving unit receives information indicating a second frame length and the delay indexes; the subtractor subtracts the stored state indexes from the delay indexes; and the competitive access adjustment unit determines frame timing and the second frame length according to the result of subtraction, and indicates the avoidance frequency acquisition unit to work according to the second frame length and the determined frame timing.
