Description

Radio communications system

Technical field

The present invention relates to radio communications system, this system has mobile station apparatus, base station equipment and base station control device, and uses self-adaptive modulation method.

Background technology

Up to now, using WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) in the radio communications system, to carry out packet expansion-be called HSDPA (High SpeedDownlink Packet Access, high speed downlink packet inserts)-technology carry out standardized work and obtained progress.In this radio communications system, communication is at traditional WCDMA channel-be called DPCH (Dedicated downlink Physical channels, the private downlink physical channel)-upward carry out, and IA High Speed Channel-be called HSDSCH (High Speed Downlink Shared Channel, high speed descending sharing channel)-departures to receive be executed in parallel simultaneously.

In this HSDSCH channel, use is called the technology of Adaptive Modulation, thereby change modulator approach and encoding rate according to the propagation path condition, and each mobile station apparatus is reported-is called CQI (Channel Quality Indicator, channel quality indication) report and the propagation path condition is notified to base station equipment by sending departures pilot channel condition of acceptance.

Fig. 1 is the figure of the CQI value of explanation indication propagation path quality.There is shown an example, used 22 grades of CQI values in this example, corresponding to CQI value 0 to 21.In this case, when mobile station apparatus determines that the propagation path condition is relatively poor, it will hang down the CQI value reporting and give base station equipment, and when it determines that the propagation path condition is better, give base station equipment with high CQI value reporting.When basic signal incoming level did not reach predetermined threshold (promptly outside scope), mobile station apparatus report CQI value was 0.

Base station equipment is according to the CQI value by each mobile station apparatus report, determining to become the mobile station apparatus that sends target, and utilize HS-SCCH (High Speed Shared Control Channel, High-Speed Shared Control Channel) will be for example, the control information of modulator approach, multiplexed code number and information bit sends to this mobile station apparatus.Mobile station apparatus receives HS-SCCH, and to determine whether to exist with himself be the transmission of destination, oneself is the destination if its determines to send with it, then this mobile station apparatus just the information that in control information, transmits of use come demodulation and decoded data.
