Patent ID: 6889041

Claim:
A mobile communication system comprising a mobile station apparatus that transmits data transmission rate request value, and a base station apparatus that selects the mobile station apparatus to which data is transmitted based on the data transmission rate request value received from the mobile station apparatus and transmits data to the selected mobile station apparatus at the data transmission rate request value received from the selected mobile station apparatus, wherein the mobile station apparatus comprises: first receiving means for receiving an average data transmission rate transmitted from the base station apparatus; measuring means for measuring quality of the received signal from the base station apparatus; deciding means for deciding the data transmission rate request value based on the reception quality measured by said measuring means; first calculating means for calculating a difference between the data transmission rate request value decided by said deciding means and the average data transmission rate received by said first receiving means; judging means for judging whether or not the result of calculation by said first calculating means is equal to or larger than a reference value; and first controlling means for making the data transmission rate request value decided by said deciding means be transmitted to the base station apparatus when it is judged by said judging means that the result of calculation by said first calculating means is equal to or larger than the reference value, and wherein the base station apparatus comprises: second receiving means for receiving the data transmission rate request value transmitted from the mobile station apparatus; selecting means for selecting the mobile station apparatus to which data is transmitted based on the data transmission rate request value received by said second receiving means; second calculating means for calculating an average of a data transmission rate for transmitting data to the mobile station apparatus selected by said selecting means as the average data transmission rate; and second controlling means for making the average data transmission rate calculated by said second calculating means be transmitted to the mobile station apparatus.
