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.

Abstract: Conventionally, there is a problem that a state transition of E-TFC changes according to QoS for descriptions of data to be transmitted, and therefore a mobile station's operation is not decided uniquely. To solve this problem, a transmission control method in accordance with the present invention includes a step of selecting transmission control information according to a combination of user data transmitted, via a transport channel, from an upper layer, and a step of transmitting the transmission control information, as well as a physical channel into which two or more transport channels are multiplexed, to a fixed station, the transmission control information including at least transmit power information.

Abstract: When a mobile station transmitting a plurality of channels having different transmission timings such as a DPDCH and a HS-DPCCH in uplink measures transmission power over a transmission power measurement period with a slot of the DPDCH as a reference, the transmission timing difference between the channels affects the accuracy of the transmission power measurement. Therefore, a transmission power measurement period is changed depending on transmission timings of the uplink channels such as the DPDCH and the HS-DPCCH, the presence or absence of the HS-DPCCH in addition to the DPDCH, or specifications (version) of the standard applied to the mobile station.

Abstract: In a communications system, a mobile station sends a transmission request for permission to transmit packet data to a base station and transmits the packet data to the base station according to transmission schedule information about a transmission schedule which the base station determines in response to the transmission request, and the base station transmits a result of judgment of reception of packet data which it has received to the mobile station. The mobile station transmits transmission request information about new packet data which it will transmit to the base station next before completing reception of a result of judgment of reception of packet data which the mobile station has transmitted to the base station from the base station. As a result, since the mobile station can notify a transmission request for permission to transmit next packet data to the base station efficiently, a delay time which occurs due to retransmission of packet data can be shortened.

Abstract: A mobile station includes a transmission data storage unit for temporarily storing at least one or more input packet data, a priority control unit for generating priority information which a base station uses for determination of a schedule in advance based on the priority of at least the one or more packet data, and a transmitting unit for transmitting the priority information to the base station. Therefore, to generate a schedule such as a transmission timing at which the base station communicates with each mobile station, the base station can know the priority of packet data stored in each mobile station in advance, and can recognize the existence of a mobile station which is trying to transmit packet data with a high priority to the base station at an early stage. As a result, the base station can assign a transmission timing etc. quickly to the mobile station.
