摘要： A wireless communication apparatus in a first wireless system is provided with first, second and third units, and a controller. The first unit transmits frames over a frequency channel using a short or long IFS as compared with a specific one used in a second wireless system with a communication range wider than the first wireless system. The second unit receives frames over the channel. The third unit determines an error characteristic in the received frames and/or a busy status of the channel. The controller controls at least either one of whether to change the frequency channel or not, and whether to change a duration of an interframe space or not.

摘要： According to one embodiment, a wireless communication terminal including a receiver, a first processor, a first storage, a second storage, a second processor, and a transmitter is provided. The receiver receives one physical packet that includes at least one frame body field, a first field including information on a length of the frame body field, a second field used to detect an error of the frame body field, and a sequence number field including a sequence number corresponding to the frame body field. The second storage retains a successively and successfully received maximum sequence number on the basis of a result of the first processor. The transmitter transmits a response frame indicating the successively and successfully received maximum sequence number when the first processor extracts at least one correct frame body.
