摘要： A wireless device is capable of transmitting a plurality of frames to the same destination in parallel using a plurality of frequency channels. The wireless device includes: a first transmitter 21 which transmits a frame using a first frequency channel; a second transmitter 22 which transmits a frame using the second frequency channel; and a controller 43 which provides a frame stored in a buffer to the first transmitter if the first frequency channel is determined idle before the second frequency channel is determined idle. The controller 43 provides a frame stored in the buffer to the second transmitter if it is determined that a state that the second frequency channel is idle has continued for a second time before if it is determined that a state that the first frequency channel is idle has continued for a first time. The wireless device configured as above can prevent throughput reduction and suppress the occurrence of a delay beyond an allowable range.

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.
