Patent ID: 8780690

Claim:
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 OFDMA base station, and wherein the second set of synchronization channel signal sequence elements is based on a second sequence other than a GCL sequence; and transmitting an OFDMA signal by the transmitter circuitry, the OFDMA signal including the synchronization channel signal and comprising a plurality of OFDMA symbol periods, wherein a first plurality of synchronization channel signal sequence elements are distributed over a first set of multiple proximal symbol periods of the plurality of OFDMA symbol periods and a second plurality of synchronization channel signal sequence elements are distributed over a second set of multiple proximal symbol periods of the plurality of OFDMA symbol periods.
