  • Base station apparatus, communication terminal apparatus, and communication method
    Patent number: 7292862
    Abstract: An assignment section 101 determines communication resource assignment to communication terminals based on a transmission rate at which communication is possible for each subcarrier of each communication terminal, and instructs a buffer section 102 to output forward transmission data. In addition, the assignment section 101 instructs a frame creation section 103 to perform forward transmission data symbolization, and also outputs a signal indicating communication resource assignment to each communication terminal. The buffer section 102 holds forward transmission data, and outputs forward transmission data to the frame creation section 103 in accordance with instructions from the assignment section 101. The frame creation section 103 symbolizes a resource assignment signal and transmission data to create a frame, which it outputs to a spreading section 104.

  • Communication terminal apparatus, base station, and method of radio communication
    Patent number: 6938195
    Abstract: A communication terminal apparatus returns a unit of transmission with an error detected. A base station apparatus generates information indicating a position of an error within the unit of transmission while comparing a unit of transmission returned from the communication terminal apparatus with a corresponding unit of transmission stored in a buffer previous to transmission of the unit of transmission. The base station apparatus transmits the generated information to the communication terminal apparatus. The communication terminal apparatus corrects the error of the unit of transmission on the basis of the information.
