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.

By effectively utilizing the beam pattern used at the time of the last communication, a directional link can be efficiently established, thereby reducing overhead. When establishing a link, a communication apparatustransmits a preparation frame by using the last used transmit beam pattern, thereby efficiently establishing a directional link and reducing overhead. Also, when establishing a link, the communication apparatususes the last used receive beam pattern to receive a preparation frame whose transmission timing is known, thereby efficiently establishing a directional link and reducing overhead.

A radio-communication device performs processing in a communication environment in which an OFDM (Orthogonal Frequency Division Multiplexing) modulation method is used. The radio-communication device includes a signal-reception unit that receives a MIMO (Multi Input Multi Output) signal, a data-decoding unit that decodes the MIMO signal, and a data-processing unit that processes data decoded by the data-decoding unit. The radio-communication device also includes a format-determination unit that determines, based on a relative phase difference between a previous packet field and a subsequent packet field adjacent to the previous packet field, a packet format of the MIMO signal. Further, the radio-communication device includes a control unit that stops an operation of the data-decoding unit when the data-processing unit does not support the packet format, which is determined by the format-determination unit. The operation is performed in a field that comes after a field at which the format-determination unit determines the packet format.

Radio-communication device and radio-communication method

Radio communication devices receive timing reference pulses from a timing generation device and can acquire synchronism based on the received pulses, so that even on the ultra wide band (UWB) radio communication system, where there is no carrier as exists in the conventional radio communication systems, there is no need to add a redundant preamble signal ahead of transmitted information in order to acquire initial synchronism. In order to receive an asynchronous signal, there is no need to perform detection for a very long time to find whether the signal is present or absent. The application of an access control system according to the present invention to UWB radio communication implements high-speed asynchronous radio communication.
