摘要： A wireless communication device includes a wireless transmitting/receiving part, a response channel selecting part and an oscillating part. The wireless transmitting/receiving part receives a first frame in which data destined for an address of the wireless communication device and data destined for an address of another wireless communication device are included. The oscillating part outputs a carrier signal having a frequency that corresponds to the response channel selected by the response channel selecting part to the wireless transmitting/receiving part. The response channel selecting part decides an ordinal rank for response channel selection based on the information included in the first frame and selects a response channel that corresponds to the decided ordinal rank The wireless transmitting/receiving part uses the carrier signal to transmit the response frame in the response channel.

摘要： According to one embodiment, a wireless communication apparatus includes a first wireless communication unit, a second wireless communication unit, a reception power management unit, a frequency selection unit, and a frequency-hopping management unit. The second wireless communication unit performs wireless communication by means of a second wireless communication system different from the first communication system. The reception power management unit measures reception power. The frequency selection unit selects frequency-channel data enabling the second wireless communication unit to perform communication, on the basis of the reception power measured by the reception power management unit. The frequency-hopping management unit determines a frequency channel from the frequency-channel data selected by the frequency selection unit, if the second wireless communication unit performs communication by using a frequency hopping system.

摘要： According to one embodiment, an electronic apparatus includes a transmitter circuitry, a receiver circuitry, and a processing circuitry. The transmitter circuitry transmits a first data frame including first data to a destination apparatus. The receiver circuitry receives first acknowledgment information indicative of a reception state of the first data included in the first data frame. The receiver circuitry receives second acknowledgment information indicative of a reception state of the first data included in a second data frame. The second data frame is transmitted from another electronic apparatus to the destination apparatus. The processing circuitry determines whether the first data frame is retransmitted, based on at least one of the first and second acknowledgment information.
