Claim Text:
1. A communication apparatus comprising: a plurality of reception units which receive signals from an opposed station over a plurality of lines that perform wireless communication simultaneously; a quality determination unit which determines qualities of the plurality of lines based on the received signals; a modulation scheme determination unit which determines a modulation scheme to be used for the wireless communication based on the quality of only a line over which communication is possible when it becomes impossible to perform communication over a line among the plurality of lines that perform wireless communication simultaneously; and a transmission unit which transmits information indicating the determined modulation scheme to the opposed station, wherein a flag has a first value when no line disconnection has occurred in part of the lines or immediately after a line disconnection has occurred in the part of the lines, and has a second value when a line disconnection in the part of the lines continues, and wherein when line disconnection has occurred in all of the plurality of lines and the flag has the first value, the modulation scheme determination unit selects the most stable modulation scheme, and sets the flag to be the second value.
