Claim Text:
1. A wireless communication apparatus comprising: a generation unit configured to generate a first request frame and a second request frame, the first request frame being a frame for requesting a connection with another communication apparatus and requiring an acknowledgement from the other communication apparatus, the second request frame being a frame for requesting the connection with the other communication apparatus and not requiring the acknowledgement from the other communication apparatus; a control unit configured to set, as a first value, a magnitude of a transmission power of the first request frame, and set, as a second value smaller than the first value, a magnitude of a transmission power of the second request frame; a transmission unit configured to transmit the first request frame at a first time interval until an acknowledgement frame is received, and transmit the second request frame at a second time interval until an accept frame is received, the acknowledgement frame being a frame for responding to the first request frame, the accept frame being a frame for responding to the second request frame and including a request transmission power information which indicates information about a transmission power requested by the other communication apparatus, the second time interval being longer than the first time interval; a reception unit configured to receive the acknowledgement frame and the accept frame; and an analysis unit configured to analyze the request transmission power information, wherein: the control unit determines a transmission power of a data frame based on the request transmission power information, and the analysis unit extracts a frame type information specifying a type of frame included in the acknowledgement frame, and the generation unit transmits the first request frame if the frame type information indicates the first request frame.
