    • The present invention makes it possible to obtain the transmission diversity effect by applying a CDD while reducing the inter-code interference when performing a code multiplexing. When an Ack/Nack signal is transmitted from a user terminal to a base station in an upstream control channel by using an Ack/Nack resource, the signal is code-multiplexed by using a code sequence containing an orthogonal sequence and a cyclic-shifted sequence and transmitted from a plurality of user terminals to the base station. Upon using an aggregation size indicating the number of control signals of the downstream control channel, if the aggregation size is greater than one, it is determined that no resource located at the right of the axis of the cyclic-shifted amount of the cyclic-shifted sequence in the same orthogonal code of the orthogonal sequence is used, and the Ack/Nack signal to which CDD is applied from a plurality of antennas is transmitted by using a resource ACK #0 allocated to the own device and an unused resource ACK #1, which have the same orthogonal code, but have different cyclic-shifted amounts.
    • 本发明通过在执行码复用时减少码间干扰同时应用CDD可以获得发送分集效果。 当Ack / Nack信号通过使用Ack / Nack资源从用户终端发送到上行控制信道中的基站时,通过使用包含正交序列和循环移位序列的码序列对信号进行码复用 并从多个用户终端发送到基站。 当使用指示下游控制信道的控制信号数量的聚合大小时,如果聚合大小大于1,则确定不存在位于循环移位量的循环移位量的轴右侧的资源 使用正交序列的相同正交码中的序列,并且通过使用分配给自身设备的资源ACK#0和未使用的资源ACK#1来发送从多个天线施加CDD的Ack / Nack信号 ,其具有相同的正交码,但具有不同的循环移位量。

    • Disclosed are a wireless transmission apparatus and transmission power control method which improve the error rate characteristics of data signals even when the number of streams of data signals increases, without increasing the amount of signaling. The relationship between the number of streams of data signals in each antenna (201-1, 201-2) and the data signal and pilot-signal transmission power ratio at each antenna (201-1,201-2) is stored. Specifically, a relationship where the data signal and pilot signal transmission power ratio at each antenna increases as the number of streams of data signals at each antenna increases is stored. A transmission power control unit (205) determines the data signal and pilot signal transmission power ratio on the basis of the information of the number of streams of data signals at each antenna (201-1, 201-2) that were output from a decoding unit (204), controls the transmission power of the pilot signals on the basis of the determined transmission power ratio, and outputs to a multiplexing unit (210).
