RADIO COMMUNICATION APPARATUS AND METHOD FOR CONTROLLING TRANSMISSION POWER

摘要

Turbo decoding section 102 performs turbo decoding on demodulated data, counting section 103 counts the number of iterations in turbo decoding, CRC decision section 104 performs CRC on the decoded data, increment/ decrement value calculating section 105 calculates an increment or decrement value in reference SIR according to the presence or absence of an error and the number of iterations, reference SIR updating section 106 adds the increment or decrement value in reference SIR and a current reference SIR value to obtain a new reference SIR value, comparing section 108 compares an SIR value of a received signal measured in SIR measuring section 107 with the updated reference SIR value, and transmit power control bit generating section 109 generates a transmit power control bit according to the compared result.
