摘要： A method for counting correctly substantial transmission times of a data unit such as an RLC-PDU even if the data unit is divided before being transmitted is provided. The method includes the steps of preparing a counter for the RLC-PDU (#503), making a storage portion store a pointer indicating a position of a division PDU of the RLC-PDU to be transmitted every time when the division PDU obtained by dividing the RLC-PDU is transmitted (#504), determining whether or not the transmission times should be counted along with a transmission of the division PDU to be transmitted based on the pointer of the division PDU to be transmitted and the pointer of a division PDU that was transmitted last time (#505, #506 and #507), and making the counter perform the count process when it is determined that the transmission times should be counted (#508).

摘要： Disclosed is a transmission device which transmits a systematic code obtained by adding parity bits to information bits. When the code rate of the systematic code is a value in a specific range determined by the decoding characteristic in a case where dummy bits are not inserted, a dummy bit insertion portion inserts dummy bits into the information bits and shifts the decoding characteristic, so that the code rate assumes a value outside a specific range determined by the decoding characteristic after shifting. An encoding portion performs systematic encoding of the information bits into which the dummy bits are inserted, and deletes the dummy bits from the results of the encoding to generate a systematic code, and a rate matching portion, performs rate matching such that the size of the systematic code is equal to a size determined by the physical channel transmission rate, and transmits the systematic code.

摘要： Each radio base station (11, 21) evaluates whether a radio environment between itself and a mobile station is an environment in which diversity gain is obtained or an environment in which diversity gain is not obtained and interference will be impressed upon communication with another radio base station, allows the mobile station to transmit if the radio environment is the environment in which diversity gain is obtained, disallows the mobile station to transmit if the environment is the environment in which interference will be impressed upon communication with another radio base station, and neither allows nor disallows the mobile station to transmit if the environment is an environment in which although diversity gain is not obtained, no interference will be impressed upon communication with another radio base station. The mobile station performs a transmission of uplink data if it is being allowed to transmit by one or more radio base stations and, moreover, it is not being disallowed to transmit by any radio base station.

摘要： An error rate of a TFCI of a transmission data format, and when an error rate of the TFCI becomes worse, a request to increase only the power of the TFCI is issued to the transmitter. The error rate of the TFCI is computed from the error detection result of a TrCH. Especially when the data length of the TrCH is relatively short, this method is not applied, but wasteful power consumption increases. When the data length of the TrCH is long, this method is applied to realize error rate control with the wasteful power consumption minimized.

摘要： A receiver receives data transmitted from a transmitter. The data is stored in a buffer, and a reliability value of the data is computed by a computing unit. A determining unit determines reliability of the data by comparing a reliability value of existing data in the buffer and a reliability value of the data. When the reliability value of the data is higher than a predetermined value, the existing data is combined with the data. Then, an error correcting unit performs error correcting on combined data obtained, and outputs decoded bits. If the combined data includes many errors, retransmission of the data is requested to the transmitter. When the reliability value of the data is lower than the predetermined value, retransmission of data is directly requested without combining the data with the existing data.

摘要： Disclosed herein is an error correcting apparatus for receiving a signal subjected to a repetition processing in which a part of bits of an error-correction code train are repeatedly transmitted, and decoding the received signal so as to be restored to the original data. A repetition rate calculator calculates the repetition rate of the received signal subjected to the repetition processing, a soft decision data cut-off position decision unit decides the position at which a part of the soft decision data is cut off from the soft decision data which is generated by the repetition regenerator, on the basis of the repetition rate Rr, and a bit selector cuts off the part of the soft decision data at the decided cut-off position and inputs the cut part into a soft decision error-correction decoder.
