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.
Claims30
A method of wireless communication, comprising:
- initiating, from a serving wireless node, a high speed downlink packet access (HSDPA) call to a user equipment (UE);
- applying, at the serving wireless node, a synchronization channel interference cancellation (SCHIC) algorithm to the HSDPA call;
- calculating synchronization channel (SCH) interference based on the application of the SCHIC algorithm to the HSDPA call;
- and
- eliminating, by the serving wireless node the SCH interference from the HSDPA call based at least in part on transmitting a signal for a particular high speed physical downlink shared channel (HSPDSCH) with the SCH interference removed from the signal to the UE.
An apparatus for wireless communication in a wireless communication network, comprising:
- means for initiating, from a serving wireless node, a high speed downlink packet access (HSDPA) call to a user equipment (UE);
- means for applying, the serving wireless node, a synchronization channel interference cancellation (SCHIC) algorithm to the HSDPA call;
- means for calculating synchronization channel (SCH) interference based on the application of the SCHIC algorithm to the HSDPA call;
- and
- means for eliminating, by the serving wireless node, the SCH interference from the HSDPA call based at least in part on transmitting a signal for a particular high speed physical downlink shared channel (HSPDSCH) with the SCH interference removed from the signal to the UE.
