Claim 16:
17. A method for Layer 2 (L2) handling during a cell change procedure at a user equipment (UE), comprising:
decoding a radio resource control (RRC) reconfiguration message received from a first cell, the RRC reconfiguration message including a Layer 1 (L1) configuration corresponding to a second cell, wherein the first cell and the second cell share a service data adaptation protocol (SDAP) entity and a packet data convergence protocol (PDCP) entity, the first cell and the second cell each having a separate radio link control (RLC) entity, a medium access control (MAC) entity, and an L1 entity;
in response to decoding the RRC reconfiguration message, storing the L1 configuration corresponding to the second cell;
decoding a cell change message received from the first cell, the cell change message indicating that a cell change from the first cell to the second cell is to be performed;
in response to decoding the cell change message, applying the stored L1 configuration corresponding to the second cell for data transmission and reception associated with the second cell; and
initiating a cell change to the second cell.
