Claim Text:
1. A wireless communication apparatus supporting a first wireless communication scheme and a second wireless communication scheme, wherein minimum reception sensitivity levels of physical schemes of the first wireless communication scheme and the second wireless communication scheme are equal to a first level, the apparatus comprising: a management information base which holds an attribute indicating whether or not the apparatus operates in accordance with the second wireless communication scheme; a first processing unit configured to (a) when a FALSE value is set for the attribute indicating whether or not the apparatus operates in accordance with the second wireless communication scheme, set a first power value for a maximum transmission power and set the first level for a carrier sense level and (b) when a TRUE value is set for the attribute indicating whether or not the apparatus operates in accordance with the second wireless communication scheme, set a second power value lower than the first power value for the maximum transmission power and set a second level higher than the first level for the carrier sense level; a second processing unit configured to carry out carrier sense using the carrier sense level; and a third processing unit configured to control transmission and reception of a frame via the second processing unit, wherein: the third processing unit, upon receiving an instruction to start formation of a wireless communication group from the first processing unit, and when the TRUE value is set for the attribute indicating whether or not the apparatus operates in accordance with the second wireless communication scheme, generates at least one of a beacon frame and a probe response frame both including a frame body which carries information indicating that an attribute of the wireless communication group is the second wireless communication scheme, and a communication range of the second wireless communication scheme is narrower than a communication range of the first wireless communication scheme.
