WIRELESS COMMUNICATION MOBILE STATION APPARATUS AND COMMUNICATION QUALITY INFORMATION GENERATING METHOD

摘要

A wireless communication mobile station apparatus wherein the accuracy of measuring the communication quality can be improved. In this apparatus, a desired signal power measuring part (212) uses a reference signal received from a local-cell reference signal processing part (211) to measure the power of a desired signal addressed to the local apparatus. An interference signal power measuring part (214) uses a reference signal received from an other-cell reference signal processing part (213) to measure an other-cell interference signal power removable by retransmission. An interference power calculating part (215) then uses a reference signal received from the separating part (203), the desired signal power received from the desired signal power measuring part (212) and the removable-by-retransmission other-cell interference signal power received from the interference signal power measuring part (214) to calculate an interference power that is a sum of the removable-by-retransmission other-cell interference signal power and the noise power. A communication quality generating part (216) then uses the desired signal power (S) and the sum of the removable-by-retransmission other-cell interference signal power and the noise power to generate communication quality information of the signal addressed to the local apparatus.
