“…A BWP is a set of contiguous RBs configured inside a channel bandwidth; thus, the width of a BWP may be smaller than or equal to the channel bandwidth. The motivation behind introducing BWP is such that it could be challenging to use the larger 5G bandwidths for the UEs and to support UE bandwidth adaptation to help reduce device power consumption [39]. Besides, BWPs can be of various numerologies, which can be employed to decrease the latency for particular services, such as in URLLC use cases.…”

Network slicing has been a significant technological advance in the 5G mobile network allowing delivery of diverse and demanding requirements. The slicing grants the ability to create customized virtual networks from the underlying physical network, while each virtual network can serve a different purpose. One of the main challenges yet is the allocation of resources to different slices, both to best serve different services and to use the resources in the most optimal way. In this paper, we study the radio resource slicing problem for Ultra-Reliable Low Latency Communications (URLLC) and enhanced Mobile Broadband (eMBB) as two prominent use cases. The URLLC and eMBB traffic is multiplexed over multiple numerologies in 5G New Radio, depending on their distinct service requirements. Therein, we present our optimization algorithm, Mixed-numerology Mini-slot based Resource Allocation (MiMRA), to minimize the impact on eMBB data rate due to puncturing by different URLLC traffic classes. Our strategy controls such impact by introducing a puncturing rate threshold. Further, we propose a scheduling mechanism that maximizes the sum rate of all eMBB users while maintaining the minimum data rate requirement of each eMBB user. The results obtained by simulation confirm the applicability of our proposed resource allocation algorithm.

“…A convergence to one particular solution was not possible at the end of this study phase in Release 16. However, beam management and BWP operations introduced in 5G NR 18 are considered a very good baseline for future NTN enhancements. In particular, one beam per cell and multiple beams per cell are currently supported in existing NR specifications, and these configurations are the baseline for NTN.…”

Among the several features and capabilities introduced by every new 3GPP release on 5G cellular systems, the latest Release 17 will be remembered as the first that specifies a set of enhancements and adaptations to support mobile broadband services via satellite direct access. Specifically focused on the necessary physical layer mechanism and procedure modifications, this paper will present in detail the 3GPP work about the inclusion of satellite systems in 5G networks.

“…The synchronization signal block (SSB) [11], providing synchronization to an UE, as well as the control ressource set (CORESET)0 [12], containing the first control channel information for further message reception, have to match 3GPP requirements. In addition, the newly introduced bandwidth parts (BWPs) [13] are present in the initial attach. In addition to papers like the mentioned references [11]- [13], the primary sources about NR details are the 3GPP NR specifications.…”

In contrast to legacy 5G RAN solutions, Open-RAN and especially open-source RAN projects provide enhanced configuration possibilities. This enables an operator to tailor the network more specific to its needs. At the same time, this complicates the process of setting up the network, since this configuration requires more in-depth understanding of 5G. There is a gap between the 3GPP specifications, representing the theoretical aspects and the actual deployment of a 3GPP compliant network. Therefore, we present a novel explanation drawing the link between these specifications and a practical open-source 5G network, using OpenAirInterface. We further illustrate the operability of the network in different configurations with commercial UEs, by applying the presented relations.
