摘要： It is possible to improve the CQI reception performance even when a delay is caused in a propagation path, a transmission timing error is caused, or a residual interference is generated between cyclic shift amounts of different ZC sequences. For the second symbol and the sixth symbol of the ACK/NACK signal which are multiplexed by RS of CQI, (+, +) or (−, −) is applied to a partial sequence of the Walsh sequence. For RS of CQI transmitted from a mobile station, + is added as an RS phase of the second symbol and − is added as an RS phase of the sixth symbol. A base station (100) receives multiplexed signals of ACK/NACK signals and CQI signals transmitted from a plurality of mobile stations. An RS synthesis unit (119) performs synthesis by aligning the RS phase of CQI.

摘要： Provided are a radio transmission device and a radio transmission method which can suppress lowering of the throughput caused by switching between the single carrier communication method and the multi-carrier communication method while suppressing increase of the signaling amount. A PHR threshold value setting unit (116) sets a threshold value Y1 at a position greater by a predetermined value than the PHR at which the throughput performance of the SC-FDMA coincides with that of the OFDMA. A trigger signal transmission judgment unit (117) judges that a mobile station transmits a trigger signal for switching from the OFDMA to the SC-FDMA if the PHR in the OFDMA communication method is lower than the threshold value Y1.

摘要： Provided is a radio communication base station device capable of suppressing degradation of a signal error ratio characteristic for a mobile station in the vicinity of the cell center when a plurality of signals whose transmission power is to be controlled are frequency-multiplexed or code-multiplexed. In the device (100), a classification unit (118) classifies a plurality of DPCCH according to the MCS of SCCH into a plurality of groups based on the transmission power intensity. A spread code is allocated for each DPCCH according to the classification result. A spread code for spreading a response signal (ACK signal/NACK signal) is instructed to spread units (103-1 to 103-n). The spread units (103-1 to 103-n) spread the response signal by the spread code instructed from the classification unit (118). According to the classification result in the classification unit (118), a mapping unit (104) maps the response signal after the spread to one of the subcarriers constituting the OFDM symbol.

摘要： It is an object to provide a wireless communication base station device that can prevent the decline of a system throughput due to the degradation of a utilization efficiency of a communication resource of a channel for carrying out a frequency diversity transmission when a frequency scheduling transmission and a frequency diversity transmission are concurrently carried out in multiple carrier communication. In the wireless communication base station device, a modulation unit (12) carries out modulation processing for Dch data after coding to generate a Dch data symbol. A modulation unit (22) carries out modulation processing for Lch data after coding to generate an Lch data symbol. An allocation unit (103) allocates the Dch data symbol and Lch data symbol to each sub-carrier composing an OFDM symbol and outputs the allocated sub-carrier to a multiplex unit (104). In this case, the allocation unit (103) allocates the Dch data symbol to a plurality of resource blocks where one Dch is arranged at an interval equal to integral multiples of the number of resource blocks composing a resource block group.

摘要： A base station device and a mobile station device both enabling improvement of the reception quality of transmission data at a mobile station by preventing a sequence for establishing synchronism and the transmission data from interfering with each other. In the base station device (100), a frame creating section (120) creates a frame in such a way that the transmission data and the sequence used for identifying the frame timing and the code group to which the base station scrambling code belongs are so arranged that they are not superposed on one the other at the same symbol specified by the sub-carrier and time, and an RF transmitting section (150) transmits the frame. In the mobile station device (200), an RF receiving section (210) receives the frame from the base station device (100), an SCH correlation calculating section (240) calculates the correlation by multiplying all the candidates of the sequence by the frame one by one, and a frame timing/code group detecting section (250) detects the frame timing and the code group by using the correlation value acquired from the SCH acquired from the SCH correlation value calculating section (240).

摘要： In ARQ where a plurality of mobile stations share and use a single channel for response signals (ACK/HACK signals), a wireless communication base station apparatus can prevent failure of the ARQ control. In this apparatus, a CRC part (114) performs an error detection using CRC for an uplink data, and generates, as a response signal, an ACK signal in a case of CRC=OK or a NACK signal in a case of CRC=NG. A retransmittal determining part (115) determines whether the response signal is for an initially transmitted data or for a retransmitted data. A constellation control part (116) controls, in accordance with a determination result of the retransmittal determining part (115), a constellation pattern to be used in a modulation in a modulating part (105). The modulating part (105) modulates the response signal for the retransmitted data in accordance with the constellation pattern controlled by the constellation control part (116), that is, a constellation pattern obtained by reversing the constellation pattern of the response signal for the initially transmitted data.

摘要： It is possible to provide a radio communication system, a radio base station device, and a radio terminal device capable of reducing the power consumption in a radio terminal device without thinning pilot signals used for measuring upstream line quality. In the radio base station device (100) used in a radio communication system using different frequency bands for the upstream line and the downstream line, an upstream line pilot generation unit (115) forms a CQI measuring pilot signal and an upstream line RF unit (105) transmits the communication quality measuring pilot signal by using the upstream line use frequency band in the upstream line pilot transmission section. Thus, the upstream communication quality measuring pilot signal used by the radio base station device (100) to measure the line quality is transmitted by using the upstream line frequency band and accordingly, it is possible to reduce the power consumption in the radio terminal device.
