Abstract

A method of configuring a set of active cells among neighboring cells to reduce latency and interruption for inter-cell mobility is proposed. The set of active cells is an active set of cells among which UE can do fast cell switching. The set of active cells is configured by the network based on UE measurement report or network deployment information. UE maintains the configuration and can perform pre-synchronization to the configured active cells in downlink (DL) only or in both DL and uplink (UL). UE maintains the DL/UL synchronization with the active cells, and applies configuration once UE is indicated to switch to an active cell as the target cell. Because UE maintains the configuration and DL/UL timing of the target cell before receiving the cell-switch command, the mobility latency and interruption time for inter-cell mobility is reduced.
