    • Provided is a radio communication device which can surely prevent inter-code interference while maintaining the use efficiency of an upstream line control channel and suppress separation characteristic of a response signal. The device includes: a control unit (209) which controls a cyclic shift amount of a ZC sequence used for a primary diffusion in a diffusion unit (214) and a Walsh sequence used for secondary diffusion in a diffusion unit (217) according to a PUCCH number inputted from a judgment unit (208); the diffusion unit (214) which performs primary diffusion of the response signal by the ZC sequence set by the control unit (209); and the diffusion unit (217) which performs secondary diffusion of the response signal by the Walsh sequence set by the control unit (209). The diffusion unit (214) performs primary diffusion of the response signal by using the ZC sequence having such a cyclic shift amount that the guard interval at the both ends of the detection window section is maximum in the ZC sequences having different cyclic shift amounts.
    • 提供一种能够可靠地防止码间干扰,同时保持上行线路控制信道的使用效率并抑制响应信号的分离特性的无线通信装置。 该装置包括:控制单元(209),其控制用于扩散单元(214)中的一次扩散的ZC序列的循环移位量和用于扩散单元(217)中的二次扩散的沃尔什序列,根据 从判断单元(208)输入的PUCCH号码; 扩散单元(214),其通过由控制单元(209)设置的ZC序列执行响应信号的初级扩散; 以及通过由控制单元(209)设置的沃尔什序列进行响应信号的二次扩散的扩散单元(217)。 扩散单元(214)通过使用具有循环移位量的ZC序列,在具有不同循环移位量的ZC序列中检测窗口部分两端的保护间隔最大的ZC序列进行一次扩散。

    • Provided is a receiver apparatus that can improve the flexibility of setting resource candidates used for transmitting a reference signal. In this apparatus, a setting unit (101) sets a reference signal resource candidate group including a desirable SRS resource candidate group in a macro cell and also including a desirable SRS resource candidate group in a pico cell. The setting unit (101) further generates cancel information used for canceling, from the reference signal resource candidate group, an excessive resource that is included in the reference signal resource candidate group but not included in a first desirable resource candidate group. Then, ID information of a resource pattern, which determines the reference signal resource candidate group, and the cancel information are sent to a terminal (200).
    • 提供了一种可以提高设置用于发送参考信号的候选资源的灵活性的接收机装置。 在该装置中,设置单元(101)在宏小区中设置包括期望的SRS资源候选组的参考信号资源候选组,并且还在微微小区中包括期望的SRS资源候选组。 设置单元(101)进一步产生用于从参考信号资源候选组中取消包括在参考信号资源候选组中但不包括在第一期望资源候选组中的过多资源的取消信息。 然后,将确定参考信号资源候选组的资源模式的ID信息和取消信息发送到终端(200)。
