摘要： A prior art MIMO technique assumes one-to-one communication in which a transmitter and a receiver exist and does not assume a cellular system in which plural access points and access terminals exist. When the prior art is applied to the cellular system, the characteristic can be deteriorated. MIMO signal processing is not performed in access points. Signal processing units in the access points are integrated into an access point controller controlling plural access points and the MIMO signal processing for plural access points is performed together.

摘要： A radio communication system for enabling control of a modulation scheme following variation in the propagation channel and control of a coding rate in a small amount of delay and arithmetic operation. In order to attain the object explained above, a transmitter station and a receiver station use in common the information of the maximum number of bits used for communication of each symbol. The transmitter station generates codeword by previously encoding the communication signal with the code having sufficient error correcting capability, assigns, to each symbol, the codeword to result in the maximum number of bits per symbol, and modulates and transmits the bits using the modulation scheme in which the number of bits per symbol is equal to or less than the maximum number of bits per symbol. Meanwhile, the receiver station demodulates, for each symbol, the bits with the modulation scheme, in which the number of bits per symbol is larger as the propagation channel quality is higher, among the modulation schemes in which the number of bits per symbol is less than the maximum number of bits per symbol and summarizes the demodulation results and executes the decoding process by adding the signal of zero likelihood to restore the shortage when the total sum of the number of bits per symbol in the modulation scheme used for the demodulation becomes equal to or larger than the predetermined value.

摘要： In a radio-communication system and a radio station, one or more subcarriers are grouped, and the maximum bit number per symbol of the modulation method used for each subcarrier is determined for each group and shared between a transmitting station and a receiving station. The transmitting station divides and allocates a coded signal to subcarriers in accordance with the bit number per symbol, modulates each of the allocated signals by a predetermined modulation method, and transmits the modulated signals. The receiving station demodulates the received signal by the predetermined modulation method, adds a signal having zero likelihood when the bit number per symbol of a modulation method for demodulation is different from a maximum bit number, and decodes the demodulated signal by summarizing the demodulated results.

摘要： There are provided scheduling and a resend control system, which match simultaneous communications using a plurality of carriers. For individual carriers to be used, the simultaneous resend control of the carriers is made by notifying channel information and a data decoding result and by managing the resend numbers. Even in case the communications are performed by using the carriers simultaneously between a base station and a terminal, the scheduling can be done to contain the resend control. It is also possible to improve the communication quality and the throughput.

摘要： Transmission power relative to a propagation path having a variation in gain is controlled to increase communication channel capacity, and a data rate is controlled in accordance with the variation of the increased communication channel capacity. In order to increase the communication channel capacity, the transmission power is determined so that the sum of noise power (=received noise power/propagation path gain) converted into one at a transmitter and the transmission power becomes constant. As a result, contrary to the background art, the transmission power is controlled to be reduced when the propagation path gain decreases and to be increased when the propagation path gain increases.

摘要： Freedom for relationship between division of a signal processing unit and a pilot signal is improved in a multi-carrier communication system such as OFDM. An encoded signal is divided into resource blocks and the signals are arranged independently of the arrangement of a pilot signal. The signal arranged at the same position as the pilot signal causes a puncture upon transmission.

摘要： A transmitter and a receiver share a maximum number of transmission bits per symbol as a parameter. The transmitter modulates an encoded and interleaved transmission signal in accordance with a modulation scheme which enables the transmission of one bit or more per symbol, while the receiver demodulates a received signal based on a channel quality in accordance with a modulation scheme which has a higher modulation level as the channel quality is higher. When the number of demodulated bits per symbol is smaller than the maximum number of transmission bits per symbol, the receiver deinterleaves and decodes a received signal after the demodulation on the assumption that the received signal has likelihoods of zero as much as the number of missing bits.
