Dual Carrier Load Balance Configuration

[T_ADD]

Hi, does anyone have any configuration guide for load balancing when a LTE cell gets added with 1 additional RRU to the existing cell (total of 2 RRU) with a different frequency. Thanks.

Hedex has whole section for Connection and Idle Mode Load balancing between carriers. Have you checked that?

In this example, 3 is a first cell and 6 is a second added cell. I'm using this right now and it works well.
