Ue capability indication for multi-connectivity handover

A computer-readable storage medium that stores instructions for execution by one or more processors of a source base station (SBS), the instructions to configure the SBS for a multi-connectivity handover with a user equipment (HE) and a target base station (TBS), and to cause the SBS to:

• decode HE capability information from the HE, the UE capability information indicating the UE supports multi-connectivity handover;
• decode a measurement report from the UE, the measurement report triggered based on a measurement event configured by the SBS;
• encode radio resource control (RRC) signaling for transmission to the HE, the RRC signaling including a handover command for a multi-connectivity handover from the SBS to the TBS, the handover command in response to the measurement report and the UE capability information;
• decode uplink (UL) data received from the UE, wherein transmission of the UL data is based on the handover command and takes place during the multi-connectivity handover.

• encode UE capability information for transmission to the SBS, the LIE capability information indicating the UE supports multi-connectivity handover;
• encode a measurement report for transmission to the SBS, the measurement report triggered based on a measurement event configured by the SBS;
• decode radio resource control (RRC) signaling from the SBS, the RRC signaling including a handover command for a multi-connectivity handover from the SBS to the TBS, the handover command in response to the measurement report and the UE capability information;
• and
• encode first uplink (UL) data and second UL data for transmission during the multi-connectivity handover, wherein the first UL data is encoded for transmission to the SBS and the second UL data is encoded for transmission to the TBS during the multi-connectivity handover;
