摘要： According to one embodiment, 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 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： According to one embodiment, a wireless communication apparatus in a first wireless system is provided with first, second and third units, and a controller. The first unit transmits frames over a frequency channel using a short or long IFS as compared with a specific one used in a second wireless system with a communication range wider than the first wireless system. The second unit receives frames over the channel. The third unit determines an error characteristic in the received frames and/or a busy status of the channel. The controller controls at least either one of whether to change the frequency channel or not, and whether to change a duration of an interframe space or not.
