Abstract:
1. A radio transmission apparatus that measures channel quality between the radio transmission apparatus and a communicating party and transmits to the communicating party a CQI (Channel Quality Indicator) representing a measurement value, the apparatus comprising: a memory that stores CQI update cycle information representing an update cycle of the CQI and CQI repetition count information representing how many consecutive times the same CQI is transmitted; a CQI transmission timing controller that determines a transmission timing of the CQI based on the CQI update cycle information stored in the memory and a transmission timing of the CQI based on the CQI repetition count information stored in the memory, and, when the transmission timing of the CQI based on the CQI update cycle information and the transmission timing of the CQI based on the CQI repetition count information overlap, commands to transmit the CQI at the transmission timing based on the CQI repetition count information, to the communicating party with priority; and a CQI transmitter that transmits the CQI at the transmission timings determined by the CQI transmission timing controller, according to the command.
