Early carrier aggregation preparation for handover

A method for wireless communications at a user equipment (UE), comprising:

• receiving configuration information associated with a plurality of candidate cells, wherein the plurality of candidate cells includes at least a primary cell and one or more secondary cells, and wherein the configuration information is associated with acquisition, by the UE, of one or more target secondary cell parameters before a reception of a cell switch command or secondary cell activation command, at a same time as the reception of the cell switch command or secondary cell activation command, or both;
• performing a secondary cell preparation procedure associated with the one or more secondary cells in accordance with the configuration information;
• and
• transmitting a mobility report that includes an indication of one or metrics associated with the one or more secondary cells and based at least in part on the secondary cell preparation procedure.

A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by one or more processors to:

• receive configuration information associated with a plurality of candidate cells, wherein the plurality of candidate cells includes at least a primary cell and one or more secondary cells, and wherein the configuration information is associated with acquisition, by a user equipment (UE), of one or more target secondary cell parameters before a reception of a cell switch command or secondary cell activation command, at a same time as the reception of the cell switch command or secondary cell activation command, or both;
• perform a secondary cell preparation procedure associated with the one or more secondary cells in accordance with the configuration information;
• and
• transmit a mobility report that includes an indication of one or metrics associated with the one or more secondary cells and based at least in part on the secondary cell preparation procedure.
