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 wireless communication apparatus performs bi-directional communication with an initiator. The apparatus is allocated an allocation period for data transmission from the initiator. The apparatus includes means for generating a first physical frame including an acknowledgement frame with respect to data received from the initiator, and generating a second physical frame in which a plurality of transmission data frames addressed to the initiator are aggregated. The apparatus also includes means for transmitting the first physical frame at a first transmission rate and the second physical frame at a second transmission rate, during the allocation period.

摘要： A wireless communication apparatus is disclosed. A transmitting device transmits a first aggregation frame in which first transmission data frames are aggregated. A measuring device measures a number value of retransmission of each of the first transmission data frames. A storage stores a limiting value of the number value of retransmission. A determination device determines whether the number value of retransmission of each of the first transmission data frames exceeds the limiting value. A transmission buffer buffers the first transmission data frames for which it is determined that the number value of retransmission does not exceed the limiting value, and discards the first transmission data frames for which it is determined that the number value of retransmission exceeds the limiting value, of the first transmission data frames. A retransmitting device retransmits the first aggregation frame in which the first transmission data frames buffered in the transmission buffer are aggregated.

摘要： A generation device generates a frame to be transmitted to a destination communication apparatus. The frame includes a first separation field, a first MAC protocol data unit (MPDU) following the first separation field, a second separation field following the first MPDU, a third separation field following the second separation field, and a third MPDU following the third separation field. The second separation field includes length information set to a value of zero to indicate no second MPDU directly follows the second separation field. The first MPDU includes a first MAC header, a first data field, and a first frame check sequence (FCS). The first FCS is for detecting an error occurred in at least the first data field. The third MPDU includes a third MAC header, a third data field, and a third FCS. The third FCS is for detecting an error occurred in at least the third data field.

摘要： A communication device includes a first receiver, a second receiver, a communication module, and a controller. The first receiver receives an operation signal from a remote controller. The second receiver receives a radio signal with a specific frequency. A power consumption of the second receiver is less than that of the first receiver. The communication module is capable of transmitting the operation signal to a first communication device. The controller controls power supply to the first receiver and the communication module and starts power supply to the first receiver and the communication module if the second receiver receives the radio signal. The communication module turns to a standby state if the first receiver does not receive the operation signal after start of power supply to the first receiver.
