We are studying the mobility performance, outage and the signaling overhead of conditional
handover (CHO) in Fifth Generation New Radio (5G NR). We observe that CHO will bring …

Conditional handover (CHO) is a state-of-the-art 3GPP handover mechanism used in 5G
networks. Although it improves mobility robustness by reducing mobility failures, the …

Mobility management is a critical component for any new wireless standard to be ubiquitous.
While 4G-LTE and prior wireless standards utilized vendor specific hardware and software …

This paper elaborates on Conditional Handover (CHO)-a mobility feature designed in
Release 16 of 3 rd Generation Partnership Project (3GPP), aimed at improving the reliability …

The fifth-generation (5G) and beyond cellular networks are expected to support a huge
number of mobile devices, roaming seamlessly across very small cells. Consequently, the …

Future wireless networks are expected to be ultra-dense and heterogeneous not just in
terms of the number and type of base stations but also in terms of the number of users and …

In the wake of network densification and multi-band operation in emerging cellular networks,
mobility and handover management is becoming a major bottleneck. The problem is further …

Good mobility performance is critical in cellular networks for ensuring that each user is
always connected to the best possible cell and that the handovers are executed timely to …

In typical wireless cellular systems, the handover mechanism involves reassigning an
ongoing session handled by one cell into another. In order to support increased capacity …

5G cellular networks are being deployed all over the world and this architecture supports
ultra-dense network (UDN) deployment. Small cells have a very important role in providing …
