Wireless communication apparatus and wireless communication method

A wireless communication apparatus comprising:

• a reception unit which receives a first frame with a frame length of a first length using a first wireless method;
• a storage unit which stores a part or whole of the first frame received by the reception unit;
• a transfer amount decision unit which sets a third length to be a second length when the second length decided based on the first wireless method is smaller than the first length, and sets the third length to be a value not more than the first length when the second length is not less than the first length;
• a first transfer control unit which transfers transfer information including first information of the third length to a first memory, and transfers the first frame by the first length to a second memory different from the first memory, the first information being included in the first frame, and
• a processor which analyzes the first information,
• wherein the second length is a maximum length of a MAC header specified by the first wireless method, the third length is related to an amount of information transferred to the second memory, and
• an access speed to the first memory by the processor is higher than an access speed to the second memory by the processor.
