Definitions
- Amplifying section 21 amplifies and outputs a received signal from mobile station 1. Further, the amplification unit 21 amplifies the spread signal output from the modulation unit 22 to a predetermined output and transmits the output to the mobile station 1.
- the frame generator 23 adds the transmission power control bits determined by the pattern determiner 24 to the data bits to be transmitted to form a transmission frame.
- Transport channel separation section 31 separates a control transport channel and a plurality of user transport channels from a signal (received signal) output from demodulation section 25 of base station 2.
- the control transport channel target SIR update unit 36 is a control transport channel product.
- the target SIR (target channel quality) for the control channel is updated based on the measurement result of the channel quality (for example, the number of CRC-NGs) by the quality measuring unit 35.
- the user transport channel target SIR updating section 361-36 ⁇ determines that the channel quality measured by the user transport channel quality measuring section 351-35 ⁇ satisfies the target channel quality for each user transport channel. If not, increase the target SIR for each user transport channel.
- the target SIR notification control unit 38 when receiving the notification from the control transport channel quality monitoring unit 37, the target SIR notification control unit 38 immediately sets the target SIR update unit 36 for each transport channel, 361-36 ⁇ is instructed to notify the target SIR for each transport channel at this time to the target SIR determination unit 34.
- the transmission power control bit pattern is determined based on the SIR.
- the stored target SIR is notified from the radio control station 3.
- the user transport channel target SIR updating section 361 36 ⁇ force is compared with the measured channel quality of each user transport channel and the target channel quality for each user transport channel that is set. Update the target SIR for each user transport channel.
- Receiving -OK reduces the target SIR for each transport channel by ldB.
- target SIR determination section 34 is a target SIR for a control transport channel.
- step S1002 the SIR measured by the pattern determining unit 24 and the SIR measuring unit 26 are compared with the target SIR for the received signal notified from the target SIR determining unit 34 of the wireless control station 3.
- step S212 the target SIR notification control unit 38 forces the target SIR update unit 361 36 ⁇ for each user transport channel, and immediately sends the target SIR for each user transport channel at the local point to the target SIR determination unit. Instruct 34 to notify.
- the target SIR determination unit 34 determines the target SIR for the received signal based on the notified target SIR for each user transport channel so that the channel quality of all the user transport channels satisfies the required channel quality.
- step S207 the target SIR notification control unit 38 determines the target SIR for each transport channel at the local point immediately for the target SIR updating units 36 and 361—36 ⁇ for each transport channel. Instruct part 34 to notify.
- the target SIR determination unit 34 determines the target SIR for the received signal based on the notified target SIR for each transport channel so that the channel quality of all transport channels satisfies the required channel quality.
- 6n updates the target SIR for each transport channel based on the reported target SIR.
- the minimum radio control station load increase and minimum It is possible to provide a control device and a radio communication method capable of maintaining appropriate channel quality by increasing the channel capacity between the radio control station and the base station.
