1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a source network entity, a conditional handover configuration indicative of a target cell for handover of the UE upon satisfaction of a condition, the conditional handover configuration also indicative of a beam quality threshold for a random access procedure on the target cell upon satisfaction of the condition;
initiating a handover procedure to the target cell based at least in part on satisfaction of the condition indicated by the conditional handover configuration;
determining, from a plurality of beam measurements of the target cell, at least two beams of the target cell that satisfy the beam quality threshold;
selecting a beam from the at least two beams for the random access procedure on the target cell based at least in part on a highest beam measurement result value of the at least two beams and an earliest configured random access time-frequency resource of the at least two beams; and
transmitting, based at least in part on the selected beam of the target cell, a random access request to the target cell to initiate the random access procedure on the target cell for the handover of the UE.
