Abstract: Apparatus and methods for wireless communication in a wireless communication network include initiating a high speed downlink packet access (HSDPA) call to a user equipment (UE), applying a synchronization channel interference cancellation (SCHIC) algorithm to the HSDPA call, calculating synchronization channel (SCH) interference based on the application of the SCHICH algorithm to the HSDPA call, and eliminating the SCH interference from the HSDPA call.

Abstract: Methods and apparatus for wireless communication in a wireless communication network that includes receiving a synchronization channel (SCH) signal (including a primary synchronization channel (PSCH) signal, a secondary synchronization channel (SSCH) signal, and a primary scrambling code (PCH) signal) and a part of a common pilot channel (CPICH) signal in the same portion of the slot of the frame. The aspects include determining and summing the PSCH signal, SSCH signal, and PCH signal corresponding to the portion of the slot of the frame. The aspects also include de-spreading the pilot symbol over the portion of the slot of the frame based on the summed PSCH signal, the SSCH signal, and the PCH signal and estimating an estimated pilot symbol for the portion of the slot of the frame, where the estimated pilot symbol is a sum of the de-spread PSCH signal, de-spread SSCH signal, and de-spread PCH signal.
