Handling of mac-hs/ehs reset in enhanced serving cell change

A method utilized in wireless communication systems, the method comprising:

• identifying a transmission power control bit included in an active set update message;
• ascertaining whether a transmission power control value included in the active set update message differs from the transmission power control value that an apparatus currently operates under;
• and
• based at least in part on an analysis of a transmission power control combination index, performing a serving cell change that includes undertaking a media access control status reset.

An apparatus operable in wireless communication systems, the apparatus comprising:

• means for identifying a transmission power control bit included in an active set update message;
• means for ascertaining whether a transmission power control value included in the active set update message differs from the transmission power control value that a means for receiving is currently subject to;
• and
• means for performing a media access control status reset based at least in part on an examination of a transmission power control combination index.

A computer program product, comprising:

• a computer-readable medium, comprising:
• code for identifying a transmission power control bit included in an active set update message;
• code for ascertaining whether a transmission power control value included in the active set update message differs from the transmission power control value that an apparatus currently operates under;
• and
• code for performing a serving cell change that includes code for undertaking a media access control status reset wherein the media access control status reset is based at least in part on an examination of a transmission power control combination index.
