摘要： To increase a data rate irrespective of whether the spatial correlation between channels is high or low, while ensuring compatibility with the LTE-scheme MIMO system, in a MIMO system in which a base station apparatus (eNode B) switches between SU-MIMO transmission and ZF MU-MIMO transmission based on feedback information from a mobile station apparatus (UE) to perform data transmission, the mobile station apparatus (UE) selects a PMI and an RI corresponding to an Hermitian transpose of a channel matrix indicative of channel characteristics, calculates a CQI from the PMI, and transmits the PMI, RI and CQI as feedback, and the base station apparatus (eNode B) calculates a first data rate of the case of performing SU-MIMO transmission and a second data rate of the case of performing ZF MU-MIMO transmission based on the PMI that is fed back, and selects a transmission scheme corresponding to a higher data rate between the first and second data rates.

摘要： The receiver includes a signal determiner, a soft information determiner and a soft information decoder. The signal determiner determines a complex receive value for the receive signal received from a relay station. Further, the soft information determiner obtains a soft information represented by a combination of a first probability value and a second probability value. The first probability value is derivable by adding a value depending on an overall probability density function for each symbol of a modulation alphabet including a same first bit value at a same bit position of the symbols, wherein each symbol of the modulation alphabet represents at least two bits. Further, the overall probability density function indicates a probability of receiving the complex receive value, if a signal representing the respective symbol s considered for adding was transmitted from a transmitter to a relay station, wherein the signal representing the respective symbol causes the receive signal received from the relay station. The second probability value is derivable by adding a value depending on the overall probability density function for each symbol of the modulation alphabet including a same second bit value at the same bit position of the symbols. Further, the soft information decoder decodes payload data contained by the receive signal based on the obtained soft information.
