Wireless communication apparatus and method for generating midamble and controlling transmission power

A wireless communication method, comprising the steps of:

• generating a preamble that is to be deployed at a top of a transmission frame and includes header information;
• generating a midamble that is to be deployed in a middle of the transmission frame and includes information of at least part of the header information;
• setting a transmission power value based on reception power of a received signal from an overlap basic service set (OBSS) indicated by information of a reception electric field strength in association with advanced space reuse;
• and
• transmitting the transmission frame including at least one of the preamble and the midamble based on the transmission power value.

A wireless communication apparatus, comprising:

• circuitry configured to
• receive a reception frame that includes at least one of a preamble deployed at a top of the reception frame and including header information and a midamble deployed in a middle of the frame and including information of at least part of the header information, the reception frame being transmitted based on a transmission power value which is set based on reception power of a received signal from an overlap basic service set (OBSS) indicated by information of a reception electric field strength in association with advanced space reuse;
• and
• detect the midamble from the reception frame and extract the information of the at least part of the header information included in the midamble.
