Abstract:
1. A base station apparatus comprising: a multiplication section that multiplies a specific pilot symbol or a specific data symbol among symbols included in each of frames by a code group sequence indicating a code group of a scrambling code applied to the symbols included in each of the frames, to generate a code group detection symbol, the specific pilot symbol or the specific data symbol being one of the symbols included in each of the frames; a scrambling section that multiplies the symbols included in each of the frames by the scrambling code; and a transmission section that transmits the symbols which are multiplied by the scrambling code in each of the frames, wherein: pilot symbols are arranged at both a head and a tail end of the symbols included in each of the frames, the multiplication section multiplies by the code group sequence so that a frame timing detection symbol and the code group detection symbol are arranged in the frames, the frame timing detection symbol includes the pilot symbols which are comprised of the same sequence and which are arranged at the tail end of the symbols included in a first frame and the head of the symbols included in a second frame next to the first frame, and the code group detection symbol includes the specific pilot symbol or the specific data symbol which is multiplied by the code group sequence.
