Claim Text:
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 and a second set of synchronization channel signal sequence elements, wherein the first set of synchronization channel signal sequence elements is based on a general chirp like (GCL) sequence with a sequence index defined in response to first partial cell identification information associated with the base station, and wherein the second set of synchronization channel signal sequence elements is based on a second sequence other than a GCL sequence, which has properties that enable sequence index detection; and transmitting an OFDMA signal by the transmitter circuitry, the OFDMA signal including the synchronization channel signal.
