- the modulation unit 20 performs modulation processing on the data input from the buffer unit 10 and outputs the data to the transmission unit 30.
- the modulation unit 20 can select a plurality of modulation schemes having different error tolerances in radio propagation, and performs modulation processing using a modulation scheme designated by the control unit 50 described later.
- the transmission unit 30 performs predetermined radio transmission processing on the transmission data from the modulation unit 20 and transmits the data via the antenna 40.
- the control unit 50 performs scheduling for determining the priority in transmission for the data in the data queues 10-1 to 10-N of the buffer unit 10, and determines the priority according to the scheduling result. Data is sequentially output from the buffer unit 10 to the modulation unit 20. In addition, the control unit 50 has a function of monitoring the data accumulation amount of each of the data queues 10-1 to 10-N.
- Control unit 50 selects an optimal modulation scheme according to the radio propagation environment between base station apparatus 100 and each mobile station terminal. For example, when transmitting data to the mobile station terminal 200, the control unit 50 selects a modulation scheme according to the radio propagation environment between the base station device 100 and the mobile station terminal 200 and designates it to the modulation unit 20. As a result, data transmission to the mobile station terminal 200 is performed using an appropriate modulation method.

- the control unit 50 determines that the data storage amount of the data queue corresponding to the mobile station terminal 200 (here, the data queue 10-1) is a predetermined value. If the value is greater than or equal to the value, the modulation unit 20 is instructed to perform modulation processing using a modulation method having higher error tolerance than the modulation method used at the previous data transmission timing to the mobile station terminal 200.
- the modulation scheme used at the previous data transmission timing to mobile station terminal 200 is a 16-value QAM scheme
- the modulation scheme is changed to a QPSK scheme with higher error resistance and the mobile station terminal Data retransmission to 200 will be performed.

As a result, when the amount of data stored in the data queue 10-1 is equal to or greater than the predetermined threshold (step S12, Yes), the control unit 50 retransmits the data requested for retransmission to the mobile station terminal 200.
- the transmission unit 30 is instructed to transmit the transmission power by a predetermined value higher than the transmission power at the time of data transmission to the mobile station terminal 200 (step S13).
- step S12, No when the data accumulation amount of the data queue 10-1 corresponding to the mobile station terminal 200 has not reached the predetermined threshold value (step S12, No), the control unit 50 performs the process of step S13. Thus, normal operation is performed instead of giving transmission power preferentially (step S14).
- step S 13 the power that needs to have surplus power at the retransmission timing of the data requested to be retransmitted from mobile station terminal 200 If there is no surplus power, the previous data to mobile station terminal 200 Of course, retransmission should be performed with the transmission power at the time of transmission.

- the control unit 50 shown in FIG. 5 includes a scheduling unit 51, a monitoring unit 52, and a tolerance adjustment unit 53.
- the scheduling unit 51 performs scheduling for determining the priority in transmission for the data in the data queues 10-1 to 10-N of the buffer unit 10, and according to the scheduling result, the buffer unit 10 To sequentially output the data to the modulator 20.
- the monitoring unit 52 monitors the data accumulation amount of each of the data queues 10-1 to: LO-N. Specifically, the process of step S2 in FIG. 3 and step S12 in FIG. 4 is performed.
- the tolerance adjusting unit 53 detects that the data accumulation amount of the data queue corresponding to the mobile station terminal 200 is greater than or equal to a predetermined threshold by the monitoring unit 52. In this case, control is performed to increase error tolerance in radio propagation compared to the previous data transmission to mobile station terminal 200.
- a modulation method having higher error resilience than the modulation method used for data transmission to the previous mobile station terminal 200 is designated for the modulator 20.
- Step S3 a modulation method having higher error resilience than the modulation method used for data transmission to the previous mobile station terminal 200 is designated for the modulator 20.
- the transmission unit 30 is controlled to increase the transmission power from the previous data transmission to the mobile station terminal 200 (step S 13).
- the processing operation of the base station apparatus 100 according to the flowcharts shown in FIG. 3 and FIG. 4 is the program stored in advance in the storage medium 80 such as the ROM shown in FIG. 81 can be realized by causing the computer's CPU (control unit) to read and execute it.
