Wireless communication apparatus, wireless communication system, and wireless communication method

A wireless communication method for a wireless communication apparatus, the method comprising:

• dividing data into data pieces having sizes each of which correspond to the transmission capacity of a respective one of a plurality of wireless lines and generating a first plurality of fragments;
• and
• transmitting each of the first plurality of fragments to another wireless communication apparatus respectively through the wireless line having the transmission capacity corresponding to the size of the fragment,
• wherein the first plurality of fragments are transmitted in parallel through the plurality of wireless lines,
• wherein when a failure has occurred in at least one of the plurality of wireless lines:
• detecting the wireless line in which the failure has occurred;
• dividing the data into data pieces having sizes each of which correspond to the transmission capacity of each of one or more of the wireless lines among the plurality of wireless lines other than the wireless line in which the failure has occurred, and generating a second plurality of fragments;
• and
• transmitting the second plurality of fragments through the one or more of the wireless lines among the plurality of the wireless lines other than the wireless line in which the failure has occurred.

A wireless communication apparatus, comprising:

• memory storing instructions;
• and
• one or more processors configured to execute the instructions to:
• divide data into data pieces having sizes each of which correspond to the transmission capacity of a respective one of a plurality of wireless lines and generating a first plurality of fragments;
• and
• transmit each of the first plurality of fragments to another wireless communication apparatus respectively through the wireless line having the transmission capacity corresponding to the size of the fragment,
• wherein the first plurality of fragments are transmitted in parallel through the plurality of wireless lines,
• wherein when a failure has occurred in at least one of the plurality of wireless lines, the one or more processors are further configured to execute the instructions to:
• detect the wireless line in which the failure has occurred;
• divide the data into data pieces having sizes each of which correspond to the transmission capacity of each of one or more of the wireless lines among the plurality of wireless lines other than the wireless line in which the failure has occurred, and generate a second plurality of fragments;
• and
• transmit the second plurality of fragments through the one or more of the wireless lines among the plurality of the wireless lines other than the wireless line in which the failure has occurred.
