Patent ID: 8189701

Claim:
A radio communication system comprising: a first radio station; and a second radio station; wherein the first and second radio stations have common information of a first number of bits which is equal to a maximum number of bits per a communication unit, and an encoding type list including encoding types and code lengths after encoding; wherein the first radio station is configured to: generate codewords by encoding transmission information, generate a plurality of parts of codewords by picking up a first number of bits from the codewords, transmit at least one communication unit by picking up a second number of bits which is equal to or less than the first number of bits from the parts of codewords; and wherein the second radio station is configured to: receive and demodulate at least one communication unit transmitted by the first radio station, and combine and decode the demodulated signals of the at least one communication unit, including adding a third number of signals each corresponding to a smallest likelihood, the third number of signals also corresponding to the difference of the first number of bits and the second number of bits.
