Radio communication device and radio communication method

A radio communication method comprising:

• generating demodulated data by demodulating a radio signal which is generated via a coding process and a modulating process in accordance with a transmission format of predetermined transmission formats, the demodulated data corresponding to a codeword of the coding process and including each of decision values which corresponds to each bit of the codeword respectively;
• generating each of quantization values by quantizing each of the decision values respectively;
• and
• storing, using a processor, each of the quantization values to the memory in accordance with the transmission format, so as to fit each of the quantization values within a specified number of areas which are allocated in the memory, each of the areas having a specified size, and so as to satisfy at least one of a first condition and a second condition, the first condition indicating that the specified number is fewer than the maximum first bit number corresponding to a first transmission format with which a first bit number of the codeword is maximum among the predetermined transmission formats, and the second condition indicating that the specified size is fewer than the maximum second bit number corresponding to a second transmission format with which a second bit number of each of the quantization values is maximum among the predetermined transmission formats.

A radio communication system comprising:

• a first radio communication device configured
• to generate a radio signal via a coding process and a modulating process in accordance with a transmission format of predetermined transmission formats;
• and
• a second radio communication device configured
• to generate demodulated data by demodulating the radio signal, the demodulated data corresponding to a codeword of the coding process and including each of decision values which corresponds to each bit of the codeword respectively,
• to generate each of quantization values by quantizing each of the decision values respectively,
• to store each of the quantization values to the memory in accordance with the transmission format, so as to fit each of the quantization values within a specified number of areas which are allocated in the memory, each of the areas having a specified size, and so as to satisfy at least one of a first condition and a second condition, the first condition indicating that the specified number is fewer than the maximum first bit number corresponding to a first transmission format with which a first bit number of the codeword is maximum among the predetermined transmission formats, and the second condition indicating that the specified size is fewer than the maximum second bit number corresponding to a second transmission format with which a second bit number of each of the quantization values is maximum among the predetermined transmission formats.
