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 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.

摘要： A physical header detecting unit detects a physical header from a received signal in which a first received signal intensity of a first channel or a second received signal intensity of a second channel exceeds a first threshold value. A first carrier sense unit determines that a carrier is detected when the physical header is detected. A second carrier sense unit determines whether a carrier is detected by determining whether the first or second received signal intensity exceeds a second threshold value when a physical header is not detected. A control unit controls the second carrier sense unit such that the second threshold value is lowered to temporarily increase the sensitivity of carrier sense when the second carrier sense unit performs carrier sense regarding the second channel.

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.
