Abstract

Techniques to configure a user equipment (UE) for a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding a measurement report for transmission to the SBS. The measurement report is triggered based on a measurement event configured by the SBS. Radio resource control (RRC) signaling from the SBS is decoded, the RRC signaling including a handover command in response to the measurement report. The handover command includes an indication for multi-connectivity support by the SBS and the TBS during the handover. A first protocol stack associated with the SBS and a second protocol stack associated with the TBS are configured at the UE. A packet data convergence protocol (PDCP) protocol data unit (PDU) received at the UE during the handover is processed using the first protocol stack or the second protocol stack.
