1. A method for use in an orthogonal frequency domain multiple access (OFDMA) base station in a wireless communication system including a synchronization channel generator and transmitter circuitry, the method comprising the steps of:
generating a synchronization channel signal by the synchronization channel generator, the synchronization channel signal comprising a plurality of synchronization channel signal sequence elements including a first set of synchronization channel signal sequence elements, wherein the first set of synchronization channel signal sequence elements is based on a cyclically shifted maximal length binary sequence with a cyclic shift of the maximal length binary sequence defined in response to cell identification information associated with the base station; and
transmitting an OFDMA signal by the transmitter circuitry, the OFDMA signal including the synchronization channel signal,
wherein the plurality of synchronization channel signal sequence elements includes a second set of synchronization channel signal sequence elements, and the second set is based on a sequence other than the cyclically shifted maximal length binary sequence, which has properties that enable sequence index detection.
