    摘要： A method for exchanging channel information between a transmitter and a receiver each including antennas. A request frame including a first preamble, second preamble, and channel information feedback request is transmitted to the receiver, wherein the first preamble is transmitted from one of the antennas of the transmitter, the second preamble is transmitted from each of the antennas, and the channel information feedback request is transmitted from the one of the antennas. The request frame is received at the receiver, and the channel information feedback request is detected by a decoding based on the first preamble. Channel information is estimated using the second preamble, and a notification frame including the estimated information is constructed and transmitted to the transmitter.

    摘要： A communication device includes a receiver, a transmitter and an interruption module. The receiver receives an allocation signal indicating a first period usable by the communication device and a second period usable by a plurality of communication devices including the communication device. The transmitter transmits a transmission signal in the first period. If the transmission of the transmission signal is completed within the first period, the interruption module interrupts at least a part of power supply to the receiver in the second period. If the transmission of the transmission signal is not completed within the first period and directivity of radio waves used by a second communication device includes a direction of the communication device in a communication period allocated before the second period, the transmitter transmits the transmission signal in the second period.

    摘要： A radio communication apparatus that performs first radio communication using a first channel among two first channels each having a first channel width, and second radio communication using a second channel having a second channel width that is wider than the first channel width and also having a channel width overlapping with the two first channels. The apparatus includes an interference detection device which detects that interference occurs in the first channel among the two first channels, and a frame generation unit which generates a notification frame that recommends the use of only the first channel width. An instruction unit instructs the frame generation unit to generate the notification frame when the occurrence of interference is detected by the interference detection device. A frame transmission unit transmits the notification frame generated from the frame generation unit in response to the instruction from the instruction unit.

    摘要： A communication apparatus includes a receiving device configured to receive a physical frame in which a plurality of MAC frames, each having a sequence number, are aggregated. A reception buffer which stores MAC frames of the physical frame received by the receiving device. A determination device determines whether or not the first MAC frame in the physical frame received by the receiving device has been successfully received. A reception buffer management device determines, when the first MAC frame has been successfully received, a MAC frame to be forwarded to an upper layer, on the basis of the sequence number of the first MAC frame, and extracts the MAC frame from the reception buffer.

    摘要： A radio base station apparatus used in a radio communication system in which an initiator holds a transmission opportunity (TXOP) period in a frame exchange sequence and a responder responds to the initiator in the frame exchange sequence is disclosed. The apparatus includes a setting device which sets a ratio between a first period necessary for transmitting a first frame from the initiator to the responder and a second period necessary for transmitting a second frame from the responder to the initiator. The apparatus also includes a calculation device which calculates the first period to be used by the initiator and the second period to be used by the responder, on the basis of the transmission opportunity period and of the ratio which is set.

    摘要： A radio communication apparatus includes a first processing unit which performs physical layer protocol processing in order to make a radio communication using at least one first channel having a first frequency bandwidth and a second processing unit which performs physical layer protocol processing in order to make a radio communication using a second channel which has a second frequency bandwidth. The second frequency bandwidth has a bandwidth wider than that of the first frequency band. A transmission frame including either information of a traffic class, a capability of a destination terminal, a recommended bandwidth by the destination terminal, and a time limit to complete transmission of a frame is stored in a queue. A scheduler controls a time when the transmission frame is output from the queue, and which of the first and the second processing units should be used for the output transmission frame, based on the information.
