  Heterogeneous networks have been studied as one of the enablers of network
densification. These studies have been intensified to overcome some drawbacks
related to propagation in millimeter waves (mmWaves), such as severe path and
penetration losses. One of the promising heterogeneous nodes is
network-controlled repeater (NCR). It was proposed by the 3rd generation
partnership project (3GPP) in Release 18 as a candidate solution to enhance
network coverage. In this context, this work performs a system level evaluation
to analyze the performance improvement that an NCR can cause in its serving
cell as well as its interference impact on neighbor cells. Particularly, the
results show a considerable improvement on the performance of user equipments
(UEs) served by the NCR, while neighbor UEs that receive the NCR signal as
interference are negatively impacted, but not enough to suffer from outage.
