Abstract

A mobile station includes an amount-of-data information determining means for monitoring data which are stored on a communication-service-by-communication-service basis or on a transmit-channel-by-transmit-channel so as to determine communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information. The mobile station transmits the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information determined by the amount-of-data information determining means to a base station.

a transmitting means for transmitting the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information determined by said amount-of-data information determining means to a base station.

2. The mobile station according to claim 1, characterized in that said amount-of-data information determining means converts the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information into a binary digit number, and outputs the amount-of-data information indicating the binary digit number to the transmitting means.

3. The mobile station according to claim 1, characterized in that said amount-of-data information determining means converts the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information into a data occupation ratio of the transmit buffer, and outputs the amount-of-data information indicating the data occupation ratio to the transmitting means.

4. The mobile station according to claim 1, characterized in that said amount-of-data information determining means converts the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information into a time, and outputs the amount-of-data information indicating the time to the transmitting means.

5. The mobile station according to claim 1, characterized in that said amount-of-data information determining means converts the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information into a transmission rate, and outputs the amount-of-data information indicating the transmission rate to the transmitting means.

6. The mobile station according to claim 5, characterized in that said amount-of-data information determining means converts the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information into a number of bits per second or a number of bits per unit time.

7. The mobile station according to claim 1, characterized in that said amount-of-data information determining means converts the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information into a channel amplitude coefficient or a channel amplitude coefficient ratio, and outputs the amount-of-data information indicating the channel amplitude coefficient or the channel amplitude coefficient ratio to the transmitting means.

8. The mobile station according to claim 1, characterized in that said amount-of-data information determining means converts the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information into a power dimension or a power dimension ratio, and outputs the amount-of-data information indicating the power dimension or the power dimension ratio to the transmitting means.

9. The mobile station according to claim 1, characterized in that said amount-of-data information determining means outputs an index indicating a combination of pieces of communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information to the transmitting means, instead of the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information.

10. A base station comprising:

a receiving means for receiving communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information from a mobile station;

an assignment determining means for determining assignment of radio resources for data on a communication-service-by-communication-service or transmit-channel-by-transmit-channel basis according to the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information received by said receiving means; and
