Abstract
This paper targets at evaluating different mechanisms
for providing Inter-Frequency (IF) Load Balancing (LB)
in advanced multi-layer deployments. In particular, the performance
of IF mobility management based on signal quality
measurements is compared against a load-dependent Traffic
Steering (TS) framework that triggers IF events only if load
imbalance is detected. To evaluate the joint interaction of the
aforementioned schemes with more advanced LB features, system
level simulations have been conducted with and without assuming
Carrier Aggregation (CA) capable terminals. Results have shown
that although the standardized signal quality-based IF mobility
management can maximize data rates, the developed framework
reduces significantly the signaling overhead, at the cost of slight
User Equipment (UE) throughput degradation. Nevertheless, the
observed trade-off almost disappears if CA is enabled, while
similar signaling gains can be achieved.
