    摘要: 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.
