Techniques to configure a UE for time-division multiplexing (TDM)-based 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 indicates the UE supports the TDM-based 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 from the SBS is decoded, which includes a handover command in response to the measurement report. The handover command indicates a TDM pattern for multi-connectivity with the SBS and the TBS during the handover. UL data is encoded for transmission to the SBS. Transmission of the UL data to the SBS is time-division multiplexed with communications between the UE and the TBS during the handover based on the TDM pattern.

Multi-connectivity using time division multiplexing

Techniques to configure a user equipment (UE) for radio link failure (RLF) handling during 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 via a first communication link. The measurement report is triggered based on a measurement event configured by the SBS. RRC signaling is received from the SBS, 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 random access channel (RACH) procedure with the TBS is performed using a second communication link between the UE and the TBS. Radio link monitoring (RLM) on the first communication link and the second communication link is performed during the handover.
