1. A method for inter-cell mobility at a user equipment (UE), comprising:
decoding a first radio resource control (RRC) reconfiguration message received from a first cell, the first RRC reconfiguration message comprising a first portion of configuration information for performing a cell change to a second cell;
decoding a cell change message received from the first cell, the cell change message indicating that a cell change to the second cell is to be performed;
encoding a cell change acknowledgment for transmission to the second cell; and
decoding a second RRC reconfiguration message received from the second cell, the second RRC reconfiguration message comprising a second portion of configuration information for performing the cell change to the second cell, the second portion of configuration information comprising a remaining portion of configuration information to perform the cell change to the second cell.
