摘要： A mobile terminal selects a radio base station that is the access point for the mobile terminal in accordance with received-radiowave characteristic values for respective radio base stations. The multiple radio base stations include a macrobase station and multiple picobase stations. Each picobase station includes a load measurement unit adapted for measuring or calculating the communication load index of the picobase station itself; an adjustment-value setting unit adapted for setting an adjustment value that is used by the mobile terminal to change the received-radiowave characteristic value of the picobase station itself, depending on the communication load index; and an adjustment-value signaling unit adapted for signaling the adjustment value set by the adjustment-value setting unit to the mobile terminal.

摘要： In each Mobile terminal, channel impulse characteristics from radio base stations to the mobile terminal is calculated. In a radio communication system, under the assumption that each of the mobile terminals performs optimum receiving beamforming in order to receive a data signal from a radio base station that actually sends the data signal to the mobile terminal, optimum receiving beamforming characteristics are estimated for each mobile terminal. Each of radio base stations that share optimum receiving beamforming characteristics calculates precoding characteristics for each mobile terminal according to the optimum receiving beamforming characteristics such that main beams are directed to mobile terminals to which the radio base station sends data signals and null beams are directed to mobile terminals to which the radio base station does not send data signals.

摘要： In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols. Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.

摘要： In variable rate data transmission, a data transmission method or the like is provided which enables adjustment for achieving desired erroneous rate detection. A transmitting side places a calculated error detecting code after the transmission data in each frame, generates frame data in which an R-bit series before the final bit position of the error detecting code is rearranged in inverse order, and transmits. A receiving side assumes the transmission data and error detecting code by assuming the final bit position of the frame data in each frame, conducting the assumption presuming that the rearrangement in inverse order has occurred on the transmitting side. Among the assumed final bit positions, the position determined to be errorless as a result of the error detection based on the assumed transmission data and error detecting code is determined as the final bit position. R can be greater or less than the number of bits of the error detecting code.
