摘要： In a receiving side apparatus 150, reception quality of receive data is measured by a reception quality measurement section 157, receive data errors are detected by an error detection section 156, and when an error is detected a retransmission request signal and reception quality signal are transmitted multiplexed with transmit data by a transmit frame creation section 158. In a transmitting side apparatus 100, when a retransmission request signal is received a capacity necessary for demodulating data in a receiving side apparatus 150 is detected from a reception quality signal by a scheduling section 110, and data is retransmitted at that capacity. By this means it is possible to reduce the number of data retransmissions during transmission and reception, and to improve transmission efficiency.

摘要： 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.

摘要： The base station apparatus compresses one-frame information of a broadcast channel to blocks of ½ of one frame or less and repeatedly sends this block in a one-frame time. The mobile station apparatus decodes the received signal in block units or added block units to carry out error detection. The mobile station apparatus receives and adds up the next block in the case that the error rate exceeds a threshold. The mobile station apparatus repeats this until the error rate falls below the threshold. When the error rate falls below the threshold, the mobile station apparatus stops reception of broadcast channel signals and uses the rest of time until a one-frame time elapses to monitor carrier information of a different mobile communication system for handover.

摘要： A signal received by a receiving antenna is input to an UDMV through a detector, and compensation for distortion caused by multipath fading and an error correction using Viterbi decoding are simultaneously performed, obtaining demodulation data. The UDMV comprises a demodulator in which an MLSE and a Viterbi decoder are combined. Thereby, equalization for removing a line distortion and reduction in an error rate can be simultaneously performed, improving a receiving quality.

摘要： Radio section 103 multiplies modulated transmission signals A to D respectively by a carrier with a frequency of fA, fB, fC or fD, thereby performs the frequency conversion, and outputs the resultant signals to switch 104. Switch 104 switches between frequency conversion sections fA to fD and between antennas A to D to connect, and timing control section 105 outputs a timing control signal to switching control section 107 at time intervals for which timer 106 is preset. Switching control section 107 controls the switching of switch 104 according to switching patterns which are preset in switching pattern storage section 108 and which are each indicative of a connection relationship between antennas A to D and frequency conversion sections fA to fD.
