Abstract:
A de-spreading unit 104 de-spreads a path timing information after A/D conversion, using a specified code of a signal from an RF unit 102; a TPC judgment unit 106 makes a decision of valid TPC data, if the de-spread signal was found to contain a symbol data of a CPICH, for which channel estimation has been completed on the same time axis with a symbol data of a TPC for each base station, at a correct position; and transmission power control unit 107 controls transmission power of the RF unit 102 so as to attain transmission power adapted to the TPC result.
Abstract(Chinese):

解扩单元104使用来自RF单元102的信号的指定码来对A / D转换之后的路径定时信息进行解扩; 如果发现解扩信号包含CPICH的符号数据，TPC判断单元106在相同的时间轴上已经完成了信道估计的TICH的符号数据，则TPC判断单元106进行有效的TPC数据的判定， 每个基站在正确的位置; 并且发送功率控制单元107控制RF单元102的发送功率，以便获得适合于TPC结果的发送功率。
