RADIO COMMUNICATION APPARATUS AND METHOD FOR CONTROLLING TRANSMISSION POWER

摘要

A radio communication apparatus comprising a section (102) for turbo-decoding demodulated data, a section (103) for counting the iterations of turbo-decoding, a section (104) for performing CRC check of decoded data, a section (105) for calculating the increment/decrement of the reference SIR depending on the presence/absence of an error and the number of iterations, a section (106) for adding the increment/decrement of the reference SIR to a current reference SIR value to determine a new reference SIR value, a section (108) for comparing the SIR value of a received signal measured by an SIR measuring section (107) with an updated reference SIR value, and a section (109) for generating a transmission power control bit according to the comparison results.
