UE CAPABILITY INDICATION FOR MULTI-CONNECTIVITY HANDOVER

Abstract:

Techniques to configure a UE for a multi-connectivity handover with a source base station (SBS) and a target base station (TBS) include encoding UE capability information for transmission to the SBS, the UE capability information indicating tire UE supports multi-connectivity handover. A measurement report is encoded for transmission to the SBS, the measurement report triggered based on a measurement event configured by the SBS. RRC signaling is received from the SBS and includes a handover command for a multi-connectivity handover from the SBS to the TBS. The handover command is in response to the measurement report and the UE capability information. First UL data and second UL data are encoded for transmission during the multi-connectivity handover. 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.
