Abstract: A transmission apparatus capable of improving overall throughput of a system by suppressing peaks using some frequencies in a communication band. In this apparatus, modulation section (102) adaptively modulates transmission data. Combination section (103) combines the waveform of the transmission data and the waveform of an inverse replica and suppresses peaks equal to or higher than a threshold. When there are peaks equal to or higher than a threshold, inverse replica generation section (112) extracts the waveform of a peak equal to or higher than the threshold and generates an inverse replica which is the waveform having the inverse characteristic of the extracted waveform. Where MCS is set for each subcarrier, sub-band selection section (114) selects the frequency of a subcarrier having large margin in reception quality and outputs the inverse replica within the range of the selected frequency to combination section (103).

Abstract: Complex correlation section 110 complex-multiplies baseband signals obtained by frequency-converting known signals sent from base station apparatuses, which are candidate communication partners, to baseband frequencies by known patterns to distinguish signals of the respective base station apparatuses, despreads the baseband signals and obtains amplitude values. Desired signal power measuring section 111 averages the amplitude values with a predetermined number of symbols, interference signal power measuring section 112 that calculates a desired signal power value by suppressing the interference component separates the interference component by subtracting the desired signal power value from the amplitude values. Division section 113 divides the desired signal by the interference signal, calculates a CIR value and outputs the CIR value to transmission sections 102-1 to 102-n. Transmission sections 102-1 to 102-n carry out processing necessary for radio transmission such as modulation, coding and frequency conversion, etc. and send the signal via antenna 103.

Abstract: A directivity control section 103 performs weight control over a received signal using channel estimation and optimum weights, performs processing such as generation of the received signal and generates a plurality of weight-controlled transmission signals. A received signal demodulation section 104 extracts an SIR measurement result from the received signal. A scheduler section 105 decides which terminal should be assigned to a channel to be adaptively modulated from the SIR measurement result and at the same time decides the modulation multi-valued number and coding rate of the signal to the terminal. A transmission signal generation section 106 modulates a transmission signal such as a reference signal or packet data. A directivity switching instruction section 107 controls switching between directivities so as to maintain the same directivity after the reference signal is transmitted with a directivity until packet data is transmitted with a directivity. This makes it possible to receive packet data with high quality, improve efficiency of a radio frequency band and maximize communication path utilization efficiency.

Abstract: A base station transmits downlink signals to mobile terminals of users A to C with respective transmission power corresponding to downlink quality. A downlink quality estimating section (106) uses the transmission power from a transmission power control section to compare transmission power between the users, and estimates that a terminal with low transmission power has high downlink quality. The priorities are determined so that the priority is increased as the transmission power is lower. Thus determined priority information is output to a scheduling section (107). The scheduling section (107) performs scheduling based on the priority information. The section (107) assigns DSCH to terminals in ascending order of transmission power. User A is first assigned DSCH, user B is second assigned DSCH, and user C is third assigned DSCH. It is thus possible to perform scheduling and MCS selection of DSCH with the need of information from a terminal eliminated.

Abstract: Data streams stored in buffers (101) are modulated by modulation sections (102). Multipliers (103) multiply the signals output from the modulation sections (102) by weights output from a weight control section (112). The signals output from the multipliers (103) are added up by addition sections (104), subjected to radio transmission processing by transmission radio sections (105) and sent through antennas (106). A buffer control section (111) controls the buffers (101) based on a retransmission count output from a retransmission count detection section (110). The weight control section (112) outputs weights different from weights at the time of previous transmission to the multipliers (103) every time data is retransmitted. This allows a diversity gain at the time of data retransmission to be increased even if a time variation of the propagation path environment for radio signals is slow.
