    摘要: Provided is a communication device, which is enabled to improve the throughput of a communication system by reducing the difference of a transmission power between an SCCH and an SDCH thereby to satisfy the required quality of a PAPR. In this device, an MCS selection unit (111) of a transmission unit (110) decides, with reference to a CQI lookup table, an MCS pattern (MCS1) of the SDCH, an MCS pattern (MCS2) of the SCCH and information (multiplex information) on multiplex positions on the time axes of those two channels, on the basis of the CQI information. On the basis of the MCS2 and the MCS1, encoding modulation units (112 and 113) perform encoding and modulating operations. According to the multiplex information, a channel multiplexing unit (114) time-division multiplexes the SCCH and the SDCH thereby to generate a transmission signal.

    摘要: Provided is a radio communication device which can suppress inter-code interference between an ACK/NACK signal and a CQI signal which are code-multiplexed. In this device, a diffusion unit (214) diffuses the ACK/NACK signal inputted from a judgment unit (208) by using a ZC sequence. A diffusion unit (219) diffuses the CQI signal by using a cyclic shift ZC sequence. By using a Walsh sequence, a diffusion unit (216) further diffuses the ACK/NACK signal which has been diffused by using the ZC sequence. A control unit (209) controls the diffusion unit (214), the diffusion unit (216), and the diffusion unit (219) so that the minimum value of the difference between the CQI signals from a plurality of mobile stations and a cyclic shift amount of the ACK/NACK signal is not smaller than the minimum value of the difference between the cyclic shift amounts of the ACK/NACK signals from the plurality of mobile stations.

    摘要: Provided is a mobile station capable of effectively reporting control information in RACH. In the mobile station, a signature selection unit (111) selects one of different code sequences as a signature according to inputted control information and a modulation unit (112) modulates a signature (code sequence). In a table provided in the signature selection unit (111), for control information '000', CAZAC sequence #1 as a basic code sequence and a derived code sequence of shifts 0 to 7 derived from the CAZAC sequence #1 are set while being correlated to each other. The derived code sequence of shifts 0 to 7 of the CAZAC sequence #1 respectively correspond to signatures #1 to #8. Moreover, for control information '001', CAZAC sequence #2 as a basic code sequence and a derived code sequence of shifts 0 to 7 derived from CAZAC sequence #2 are set while being correlated to each other. The derived code sequence of shifts 0 to 7 of the CAZAC sequence #2 respectively correspond to the signatures #9 to #16.
