摘要： A communication apparatus to transmit a plurality of frames in a network, where each frame includes one or more symbols having a symbol length, includes a data processing unit. The data processing unit acquires an inter-frame space between two consecutive frames from the plurality of frames. The data processing unit further adjusts the inter-frame space between the two consecutive frames upon determination that the inter-frame space is not an integral multiple of the symbol length. The communication apparatus also includes a transmitter unit to transmit the adjusted consecutive frames.

摘要： Suitable beam pattern control is performed while performing access control based on physical carrier sense.A communication device transmits frames having a long preamble under a state where signals will not reach unless a beam pattern is formed, thereby enabling access control based on physical carrier sense, and under a state where signals will sufficiently reach without a beam pattern being formed transmits frames having a shorter preamble, thereby suppressing transmission overhead. Also, a beam pattern and preamble type are decided based on transmission/reception history of access control following CSMA/CA procedures.
