摘要： It is possible to provide a radio resource management device, a radio communication base station device, and a radio resource management method which can reduce a reply signal inter-cell interference and suppress decrease of the number of ACK/NACK which can be transmitted. When a plurality of CCE are allocated for PDCCH transmission, among usable CCE, the CCE number used between adjacent cells is differentiated. More specifically, a different RN satisfying RN=(usable CCE number m) mod N is allocated to the adjacent cell. A mobile station performs ACK/NACK transmission by using a PUCCH resource corresponding to the CCE number which becomes the allocated RN.

摘要： A radio communication apparatus, a radio communication method, and a radio communication system, which are capable of improving receiving reliability of predetermined bits such as bits having a high degree of importance, and the like, are provided. A code length L is decided based on the modulation system and the coding rate being specified, and the bit length of S2. The relay station decides a coding rate of S1 from the code length L. In the case of 16 QAM, since a half of all bits correspond to the bits used as the object of the quadrant discrimination, the bit length of S1 is set to L/2. Therefore, the coding rate of S1 is 2(LS1)/L, where the bit length of S1 is LS1. In the present example, S1 is coded and gives S1+P1, and S2 is coded and gives S2+P4. P1 denotes the parity bit of S1, and P4 denotes the parity bit of S2. The relay station changes the bit arrangement such that all bits of the code word (S1+P1) of S1 come to the position of the quadrant discrimination in the constellation of 16 QAM respectively.

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.
