| 20100167779 | HANDLING OF MAC-HS/EHS RESET IN ENHANCED SERVING CELL CHANGE - Systems and methodologies are described that effectuate and/or facilitate MAC-hs/ehs resets in an enhanced serving cell. In accordance with various aspects set forth herein, systems and/or methods are provided that identify transmission power control bits included in active set update messages received from source or target base stations, ascertain whether or not transmission power control values included in the active set update messages differ from transmission power control values that the system currently operates under, and performs serving cell changes and where necessary media access control status resets based on an examination of a transmission power control combination index. | 07-01-2010 |

| 20110044292 | Apparatus and Method for Increasing Reliability of Serving Cell Change - Methods and apparatus are described herein to manage a serving cell change. A HS-SCCH monitored set is maintained to store entries for all pending serving cell change requests. The HS-SCCH for each entry is monitored for a timer period. Once a change request has been confirmed for one entry, monitoring for the other entries continues until expiration of the associated timers. | 02-24-2011 |

| 20100027503 | METHOD AND APPARATUS FOR REDUCING DATA LOSS DURING HANDOVER IN A WIRELESS COMMUNICATION SYSTEM - Techniques for buffering and resending data in order to reduce data loss during handover are described. A network controller may determine whether or not to buffer data for a user equipment (UE). The network controller may continuously buffer a predetermined amount of latest data sent to a serving Node B if a decision is made to buffer the data for the UE. In one design, the network controller may send data for the UE to a source Node B, perform handover of the UE from the source Node B to a target Node B, resend to the target Node B a portion of the data sent previously to the source Node B, and send new data for the UE to the target Node B. e.g., after the resent data. The buffer and resend feature may be selectively enabled or disabled for each data flow for the UE. | 02-04-2010 |
