摘要： 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.

摘要： A multicarrier transmitting apparatus capable of improving the data symbol error rate characteristic to improve the reception quality. In this apparatus, a replacement position deciding part (141) decides, based on a number of replacements notified of by a scheduler (110), which one of a plurality of data symbols should replaced by a second pilot. Herein, a restricted condition, which is ‘RF after replacement is equal to or greater than RF before replacement minus one’, is satisfied. A replacing part (142) replaces, in accordance with the replacement position outputted from the replacement position deciding part (141), a part of the data symbols included in a repetition signal by a second pilot symbol, and outputs the resultant replaced signal to an IFFT part (105).

摘要： A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.

摘要： A wireless communication method for improving the transmission efficiency in an upstream communication in OFDMA-TDD system or the like. An upstream transmission timing control part (108), which employs this method, controls, based on the OFDMA-TDD scheme, the transmission timings of a mobile station (#p) and a mobile station (#M) communicating with a base station (100). The upstream transmission timing control part (108) acquires information about the propagation delay times τp and τM of the mobile station (#p) and mobile station (#M). When the propagation delay time τp is shorter than the propagation delay time τM, the upstream transmission timing control part (108) decides the transmission timings of the mobile station (#p) and mobile station (#M) such that the timing at which the base station (100) starts receiving symbols from the mobile station (#p) in an upstream section is earlier, by αp times an OFDM symbol length (L) (where αp is a natural number), than the timing at which the base station (100) starts receiving symbols from the mobile station (#M) in the same section.

摘要： The present invention provides a terminal device that allows constraints on user allocation to be prevented and spread codes to be allocated in a scheduler when non-adaptive HARQ is employed using a PHICH. A codeword generator (103) generates code words (CW) by encoding data, a layer mapping unit (108) places each CW in one or a plurality of layers, a DMRS generator (110) generates a reference signal for each layer in which a CW is placed by using any resource among a plurality of resources defined by a mutually orthogonal plurality of OCCs, and an ACK/NACK demodulator (102) receives a response signal indicating a retransmission request. When a response signal requesting retransmission of only a CW placed in a plurality of layers is received, the DMRS generator (110) uses each resource having the same OCC among the plurality of resources for the reference signals generated in the corresponding layers.

摘要： A transmitter device is capable of preventing error detection of a data resource area as a result of a detection mistake of a control signal. In the device, a control unit sets, as data resource areas, only PRBs that have been imparted with numbers greater than a number that has been imparted to a PRB for which has been set a control resource area for which a downlink assignment control signal (that is, a DL grant) has been mapped. In this manner, at a terminal, if the PRB for which a downlink assignment control signal has been detected can be identified, the data resource area can be identified directly, and therefore, it is possible to prevent error detection for the data resource area as a result of a detection mistake of an uplink assignment control signal.

摘要： To improve the operation and the effect of ICIC by appropriately limiting resources of a reference signal. An SRS generating unit (154) generates an SRS as a reference signal based on SRS information transmitted from a reception unit (156), and a transmission unit (155) transmits the SRS based on the SRS information transmitted from the reception unit (156). At this time, by using information that represents an SRS drop resource as a transmission drop resource set in advance, the transmission of the SRS from the transmission unit (155) is dropped in a resource in which an SRS transmission resource used for transmitting the SRS is an SRS drop resource.

摘要： Provided are a base station, a terminal whereby erroneous detection of control information can be reduced to prevent the degradation of the system throughput. A PDCCH generation unit (104) forms a downstream allocation control information unit (i.e., DCI) including cyclic redundant check (CRC) bits, which have been masked or scrambled by use of ID information of a terminal (200), and further including a bit sequence (i.e., virtual CRC) known between the terminal (200) and the base station; and an allocation unit (108) and a multiplex unit (109) map the formed DCI to a resource region (i.e., R-PDCCH region) that can be used as any one of a downstream control channel region and a downstream data channel region. That is, the PDCCH generation unit (104) includes the virtual CRC into the DCI only when the DCI addressed to the terminal (200) is mapped to the R-PDCCH region.
