5G RAN Slicing for Verticals: Enablers and Challenges [PDF]
IEEE Communications Magazine, 2019 This article investigates the slicing concept in the 5G RAN with the related challenges and research problems. The objective is to identify the plausible options for implementing the slicing concept at the RAN level by the mobile network operator to respond to the needs of verticals. We start by identifying the different slice granularity options, that

Serving HTC and Critical MTC in a RAN Slice [PDF]
2021 IEEE 22nd International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM), 2021 We consider a slice of a radio access network where human and machine users access services with either high throughput or low latency requirements. The slice offers both eMBB and URLLC service categories to serve HTC (Human- Type Communication) and MTC (Machine-Type Communication) traffic.

The Impact of RAN Slice Bandwidth Subpartitioning on Slice Performance
2022 International Wireless Communications and Mobile Computing (IWCMC), 2022 Network slicing in 5G RAN enables building logical networks on top of physical infrastructure. In case of RAN spectrum resources are divided into small bandwidth parts then, the network function in core network, namely Network Slice Admission Control Function (NSACF) enables to limit the count of user equipments (UE) and packet data unit (PDU) sessions
