Abstract
In a wireless communication method, a base station device allocates elements of a sequence having an index indicative of a communication parameter to synchronization channel symbols generates a synchronization channel while maintaining symmetry of the sequence, and transmits signals including the synchronization channel. A mobile station device restores synchronization of the signals which are faded corrects the signals based on the symmetry of the sequence, and extracts the communication parameter.
