Abstract: The present invention groupcasts a groupcast frame in a short period of time by using millimeter wave communication. A communication device equipped with a MAC control circuit for controlling a procedure for discovering a communication partner device and a procedure for determining the best transmission sector, and also equipped with a wireless circuit for transmitting a unicast frame to the communication partner device by using the best transmission sector, wherein the MAC control circuit controls the wireless circuit so as to start a timer for each discovered communication partner device after the procedure for discovering communication partner devices is completed, and transmit a groupcast frame to communication partner devices for which the timer has not finished by using the best transmission sector upon receiving a groupcast frame transmission request from a higher layer before all timers have finished.

Abstract: A radio communication apparatus includes: processing circuitry, which, in operation, scans a radio connection destination candidate; and control circuitry, which, in operation, determines, when first initial-connection processing to the connection destination target fails, a start timing of second-initial connection processing based on a cause of the failure. The processing circuitry scans the connection destination candidate based on the start timing of the second initial-connection processing.

Abstract: A communication apparatus includes: control circuitry that controls transmission/reception of a first control frame and a first data frame used for communication with another communication apparatus, and controls transmission/reception of a second control frame and a second data frame used for communication with the another communication apparatus; first radio circuitry that performs radio communication of the first control frame and the first data frame using a first omni-directional antenna; and second radio circuitry that performs radio communication of the second control frame and the second data frame using a second directional antenna. When the first radio circuitry receives, from the another communication apparatus, a WSA frame including information on the radio communication using the second radio circuitry among a plurality of the first control frames, the control circuitry determines not to perform an association procedure between the communication apparatus and the another communication apparatus based on the WSA frame.
