Abstract: Error detection section 109 carries out error detection using demodulated data and outputs an error rate to SIR versus error rate estimation section 110. SIR versus error rate estimation section 110 estimates an SIR versus error rate and outputs the result of decision as to whether the correction of the target SIR value is necessary or not to target SIR correction section 111. Target SIR correction section 111 corrects the target SIR value based on the decision result. The information on the demodulation capability of a BTS is output to G parameter control section 112 and G parameter control section 112 determines an optimal gain factor. A G parameter indicating the determined gain factor is output to multiplexing section 107 of the BTS. The G parameter is output to SIR versus error rate estimation section 110. This makes it possible to perform communications with an optimal gain factor and target SIR during diversity handover between base stations with and without an interference canceller or between base stations with interference cancellers of different capabilities.

Abstract: An allocation section 101 in a base station apparatus of the present invention sets the transmission rate of a transmit signal for a communication terminal apparatus based on a DRC signal transmitted from that communication terminal apparatus. A power margin information detector 117 detects power margin information from a demodulated signal generated by a demodulator 115, and, using that power margin information, a power setting section 118 makes a setting so as to give the minimum transmission power value at which received signal characteristics in each communication terminal apparatus meet the desired quality. Using the set transmission power value, the base station apparatus transmits a transmit signal of the set transmission rate to a communication terminal apparatus. By this means it is possible to suppress interference to a communication terminal apparatus that performs adaptive modulation communication with another base station apparatus and a communication terminal apparatus that performs adaptive modulation communication with the local base station apparatus at the same time.

Abstract: A GI insertion section 105 inserts a guard interval into transmission data. Delay addition sections 107-1, 107-2 set a delay time in the transmission data. An arrival time calculation section 115 calculates for each directivity an arrival time after data is transmitted from the other party of communication until the data is received from received data of each directivity. A delay time determining section 116 calculates a difference in the arrival time between transmission data transmitted with two directivities and sets the calculated arrival time difference in the transmission data to be transmitted with the directivity corresponding to the smaller arrival time as a delay time. A GI length determining section 117 sets a minimum arrival time of the calculated arrival times as a guard interval. This allows a transmission rate to be improved by shortening the length of a guard interval in a radio communication system to which a system of transmitting an OFDM signal with a directivity is applied.
