Abstract: Provided is a cyclic shift sequence generation method which can prevent coming of an interference wave into a desired wave detection window even if a cyclic shift sequence has a high mutual correlation in different bandwidths, thereby improving a channel estimation accuracy in a base station. In this method, a cyclic shift sequence number to be allocated to a cell is decided in advance. Moreover, when the cyclic shift amount between cyclic shift sequences allocated in cells is Δ1 and the cyclic shift amount of the cyclic shift sequences allocated between the cells is Δ2, Δ1 and Δ2 are made different when generating a cyclic shift sequence.

Abstract: Scheduler 304 performs scheduling such that the communication terminal apparatuses to transmit packets to are determined according to the order in CIR information output from demodulator 303, and determines the modulation schemes and coding rates of the packets. Command detector 305 detects an ARQ command transmitted from the communication terminal apparatus determined in scheduler 304, outputs an ACK/NACK signals to buffer 306, and outputs a SUSUPEND signal or a GIVEUP signal to scheduler 304. Scheduler 304 stops retransmission upon receiving a SUSPEND signal or a GIVEUP signal from command detector 305, and redoes the scheduling. Thus, it is possible to improve overall system throughput in a wireless communication system that performs packet transmission.

Abstract: Data streams stored in buffers are modulated by modulation sections. Multipliers multiply the signals output from the modulation sections by weights output from a weight control section. The signals output from the multipliers are added up by addition sections, subjected to radio transmission processing by transmission radio sections and sent through antennas. A buffer control section controls the buffers based on a retransmission count output from a retransmission count detection section. The weight control section outputs weights different from weights at the time of previous transmission to the multipliers 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.

Abstract: Disclosed is a wireless communication apparatus and wireless communication method wherein flexible frequency scheduling is performed without increasing the scale of the DFT (Discrete Fourier Transform) circuitry. For example, when resource allocation information is reported indicating whether or not a resource has been allocated to each of a plurality of RBGs (RB groups) into which the system bandwidth is divided, as in Type 0 allocation, if the number of reported RBs reported by the resource allocation information cannot be expressed as “2̂n×3̂m×5̂l”, an allocated RB number setting section (208) sets the number of allocated resource blocks used in the actual transmission band, corresponding to the reported RB number, to the number of resource blocks that can be represented by any of “2̂n×3̂m×5̂l”, and an allocated RB selection section (209); selects the allocated RB employed in the actual transmission band from the resource allocation information and allocated RB number

Abstract: Disclosed are a wireless transmission apparatus and transmission power control method which improve the error rate characteristics of data signals even when the number of streams of data signals increases, without increasing the amount of signaling. The relationship between the number of streams of data signals in each antenna (201-1, 201-2) and the data signal and pilot-signal transmission power ratio at each antenna (201-1,201-2) is stored. Specifically, a relationship where the data signal and pilot signal transmission power ratio at each antenna increases as the number of streams of data signals at each antenna increases is stored. A transmission power control unit (205) determines the data signal and pilot signal transmission power ratio on the basis of the information of the number of streams of data signals at each antenna (201-1, 201-2) that were output from a decoding unit (204), controls the transmission power of the pilot signals on the basis of the determined transmission power ratio, and outputs to a multiplexing unit (210).

Abstract: A radio transmission device capable of improving the reception error rate characteristics of a receiver. In this device, an FFT (Fast Fourier Transform) unit (102) subjects a transmission signal to an FFT operation, in which a signal in a time domain is converted into a signal in a frequency domain. A control unit (103) controls the transmission power of the FFT-operated transmission signal in the frequency domain. An IFFT (Inverse Fast Fourier Transform) unit (104) subjects the transmission signal having its transmission power controlled, to an IFFT operation, in which an inverse conversion is made into a signal in the time domain. A transmission RF unit (106) transmits the IFFT-operated transmission signal on a single carrier.
