This paper deals with mobility robustness in a
context of ultra-dense deployments operating at the millimeter
wave (mmW) band. In order to increase the threshold speed of
user equipments (UEs) allowed at the small cell layer, we propose
the use of selective Control/User-plane split combined with a noncoherent
cooperative multi-point (CoMP) joint transmission (JT).
This way, users at moderate speeds can also benefit from the new
cell layer and improve their performance with respect to a pure
macrocellular operation. The combination of this strategy with
a fine tuning of the measurement gap interval allows reducing
handover failure rates, which eventually translates into a throughput
improvement. On the other hand, increasing the number of
measurements leads to a higher UE power consumption, fact that
has also been quantified and evaluated.
