摘要： In a transmission power control apparatus for measuring SIR, which is a ratio of a receive signal to an interference signal, and controlling transmission power of a mobile station in such a manner that the measured SIR will agree with a target SIR, a fading detector detects the rate of change in fading, a correction unit corrects the target SIR based upon the rate of change in fading, and a transmission power control command creation unit creates a command for controlling transmission power of the mobile station in such a manner that the measured SIR will agree with the corrected target SIR, and transmits this command. Further, a searcher detects multipath and the levels of signals that arrive via respective ones of the paths, a level-difference calculation unit calculates level differences between the paths, a correction unit corrects the target SIR based upon the level differences between the paths, and a transmission power control command creation unit creates a command for controlling transmission power of the mobile station in such a manner that the measured SIR will agree with the corrected target SIR, and transmits this command.

摘要： A base station has a time correlation calculating unit for estimating a variation-with-time characteristic of radio link quality using radio downlink quality information reported by a mobile station, a target error rate setting unit for changing over a target error rate adaptively using this variation-with-time characteristic, and an MCS decision unit for deciding a modulation scheme and/or encoding rate, in such a manner that packet error rate becomes equal to the target error rate, using the radio link quality information as well as reception success/failure information reported by the mobile station. The base station transmits a packet based upon the modulation scheme and/or encoding rate decided.

摘要： A base station device is provided with a receiver, an interference comparator, an allocation unit, and a transmitter. The receiver receives an interference parameter indicating a level of interference of the first mobile station with the second mobile station. The interference comparator compares the interference parameter with a predetermined interference threshold value. The allocation unit allocates a communication band to the first mobile station such that the probability that the first band will be allocated to the first mobile station becomes larger than the probability that the second band will be allocated to the first mobile station when a level of interference represented by the interference parameter is larger than a level of interference represented by the interference threshold value. The transmitter transmits information of an allocated band to the first mobile station.

摘要： A parity check matrix construction method for constructing a non-binary parity check matrix defining a non-binary LDPC code. In particular, a parity check matrix construction method for setting codewords able to stably give a superior decoding performance is provided. For this reason, the non-binary non-zero elements are selected so that the determinants of the partial matrices corresponding to the cycles in the parity check matrix do not become 0. Due to this, a non-binary parity check matrix able to give large weight codewords is constructed.
