Method and Apparatus for Power Correction in Uplink Syncronization During a TD-SCDMA Handover

A method of wireless communication, comprising:

• receiving, at a target Node B, a synchronization signal from a UE on an uplink pilot channel corresponding to a handover from a source Node B to the target Node B;
• determining an adjustment of a transmit power for future transmissions to a target Node B relative to the transmission of the synchronization signal from the UE;
• and
• transmitting an acknowledgment message to the UE, the acknowledgment message comprising information associated with the adjustment of the transmit power.

An apparatus for wireless communication, comprising:

• means for receiving an indication from a source Node B to perform a handover to a target Node B;
• means for transmitting a synchronization code to the target Node B;
• and
• means for receiving an acknowledgment signal from the target Node B, the acknowledgment signal comprising information associated with adjustment of a transmit power for an uplink data channel after the handover.

An apparatus for wireless communication, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor is configured to:
• receive, at a target Node B, a synchronization signal from a UE on an uplink pilot channel corresponding to a handover from a source Node B to the target Node B;
• determine an adjustment of a transmit power for future transmissions to a target Node B relative to the transmission of the synchronization signal from the UE;
• and
• transmit an acknowledgment message to the UE, the acknowledgment message comprising information associated with the adjustment of the transmit power.

A computer program product, comprising:

• a computer-readable medium comprising code for:
• receiving an indication from a source Node B to perform a handover to a target Node B;
• transmitting a synchronization code to the target Node B;
• and
• receiving an acknowledgment signal from the target Node B, the acknowledgment signal comprising information associated with adjustment of a transmit power for an uplink data channel after the handover.
