Abstract

A mobile station includes a radio link control unit for outputting or inputting data that are transmitted or received via a radio channel to or from a higher-level protocol layer, a media access control unit for outputting or inputting the data via a logical channel to or from the radio link control unit, a physical layer control unit for outputting or inputting the data via a transport channel to or from the media access control unit, and for controlling radio communications, and a radio resource control unit for outputting or inputting control data to or from the radio link control unit, media access control unit, and physical layer control unit. The mobile station multiplexes report information therefrom into a channel for packet data transmission so as to transmit it to a base station. The base station carries out assignment of radio resources using the report information.

Claims

1. A mobile station provided with a radio link control unit for outputting or inputting data which are transmitted to or received from a base station via a radio channel to or from a higher-level protocol layer, a media access control unit for outputting or inputting said data via a logical channel to or from said radio link control unit a physical layer control unit for outputting or inputting said data via a transport channel to or from said media access control unit, and for controlling radio communications with said base station, and a radio resource control unit for outputting or inputting control data to or from said radio link control unit, said media access control unit, and said physical layer control unit, characterized in that

said media access control unit multiplexes report information to be transmitted to the base station into a channel for packet data transmission so as to transmit the report information to the base station.

2. The mobile station according to claim 1, characterized in that the report information from said mobile station is placed in a header of data in a data format which is to be transmitted via the channel for packet data transmission.

3. The mobile station according to claim 1, characterized in that the report information from said mobile station is placed in a tail end of data in a data format which is to be transmitted via the channel for packet data transmission.

4. The mobile station according to claim 1, characterized in that data to be transmitted via said channel for packet data transmission have a data format having an information area indicating presence or absence of the report information from said mobile station.

5. The mobile station according to claim 1, characterized in that data to be transmitted via said channel for packet data transmission have a data format having an information area indicating a type of the report information from said mobile station.

6. The mobile station according to claim 1, characterized in that data to be transmitted via said channel for packet data transmission have a data format having an information area indicating presence or absence of packet data.

7. The mobile station according to claim 1, characterized in that data to be transmitted via said channel for packet data transmission have a data format intended for transmitting the report information from said mobile station.

8. The mobile station according to claim 7, characterized in that said intended format is added to a data format of data to be transmitted via said channel for packet data transmission, and data is transmitted to the base station in this data format.

9. The mobile station according to claim 1, characterized in that said mobile station includes a retransmission control unit for said channel for packet data transmission, and the report information from said mobile station is multiplexed to a data format of data to be transmitted via the channel for packet data transmission according to the retransmission control cycle.

10. The mobile station according to claim 1, characterized in that a part is separated from the report information from said mobile station, and is notified to a base station control apparatus.

11. A mobile station comprising:
