Abstract:
1. A method for use in a base station in a wireless communication system wherein the base station has cell identification information associated therewith, the cell identification information associated with the base station comprising first and second partial cell identification information stored in a storage device thereof, the base station further including a synchronization channel generator for generating a synchronization channel signal, and transmitter circuitry for transmitting an orthogonal frequency domain multiple access (OFDMA) signal, the method comprising the steps of: the synchronization channel generator generating the synchronization channel signal comprising at least first and second synchronization channel signals, the first and second synchronization channel signals comprising respective first and second sets of one or more individual sequence elements, and wherein the first set of one or more individual sequence elements is generated based on a general chirp like (GCL) sequence with a sequence index of the GCL sequence defined in response to the first partial cell identification information stored in the storage device of the base station, and wherein the second set of one or more individual sequence elements is generated based on a cyclically shifted maximal length binary sequence with an amount of cyclic shift of the maximal length binary sequence defined in response to the second partial cell identification information stored in the storage device of the base station; and the transmitter circuitry transmitting the OFDMA signal including the synchronization channel signal.
