ABSTRACT:
The present invention relates to an information processing apparatus and a communication apparatus for accurately recognizing at the base station the current receiving quality of the mobile terminals for improving the throughput of the base station. A mobile terminal61determines its own receiving quality based on the signal received from the base station62for generating the receiving quality message indicating the receiving quality and generates the power control information requesting the transmission power of the base station62. The receiving quality message is transmitted at a frame rate and power control information is transmitted at the slot rate to the base station62. Based on both the receiving quality message and power control information, the base station62estimates the current receiving quality of the mobile terminal61and adaptive modulation and coding is performed based on the estimated value. The present invention may be applied to cellular phones and base stations.
