Open Radio Access Network (O-RAN) alliance was recently launched to devise a new RAN architecture featuring open, software-driven, virtual, and intelligent radio access architecture. O-RAN is based on (1) disaggregated functions that run as Virtual Function (VNF) Physical (PNF); (2) the notion of controller runs centrally applications such mobility management, users' scheduling, resources allocation, etc. The in charge enforcing application decisions by using open interfaces with functions....

In this letter, we propose an O-RAN-based framework for Reconfigurable Intelligent Surfaces (RIS) control in 6G. The key objective is to enable the development of RIS algorithms as xApps running at Real-time Controller (RIC) Open RAN (O-RAN). To validate proposed framework, developed a Golang-based simulator, GoSimRIS, intended mimic and examine behavior various environmental scenarios. simulator linked with RIC via specialized Service Model (SM) devised work, namely E2SM RIS, which allows...

5G New Radio (NR) introduces several key features to support the new emerging vertical industry use-cases, mainly: (1) Different numerology that gives more flexibility in managing time slot duration, and hence satisfying different delay requirements; (2) Bandwidth part permits dedicating parts of bandwidth ensure data rate requirements. However, although NR enhancements, it makes radio resource management, precisely scheduling, complex challenging. In this paper, we address challenge...

Radio Link Failure (RLF) is a challenging problem in 5G networks as it may decrease communication reliability and increases latency. This against the objectives of 5G, particularly for ultra-Reliable Low Latency Communications (uRLLC) traffic class. RLF can be predicted using radio measurements reported by User Equipment (UE)s, such Reference Signal Receive Power (RSRP), Quality (RSRQ), Channel Indicator (CQI), HeadRoom (PHR). However, very to derive closed-form model that derives from these...

The Network Data Analytics Function (NWDAF) is a key component of the 5G Core (CN) architecture whose role to generate analytics and insights from network data accommodate end users improve performance. NWDAF allows collection, processing, analysis enable variety applications, such as User Equipment (UE) mobility UE abnormal behaviour. Although defined by 3GPP, realizing these applications still an open problem. To fill this gap: (i) we propose microservices plug 3GPP mi-croservices enabling...

Dynamic Time Duplex Division (D-TDD) is a promising solution to accommodate the new emerging 5G and 6G services characterised by asymmetric dynamic Uplink (UL) Downlink (DL) traffic demands. D-TDD dynamically changes TDD configuration of cell without interrupting users' connectivity, hence balancing bandwidth for UL or DL communication according pattern. However, 3GPP standard does not specify algorithms solutions derive configuration, i.e., number slots dedicate DL. In [1], we have proposed...

Dynamic Time Division Duplex (D-TDD) is a promising solution to address newly emerging 5G and 6G services characterized by asymmetric dynamic uplink (UL) downlink (DL) traffic demands. However, there are two major issues: (i) determining the TDD scheme (i.e., number of slots devoted UL DL) meet demands Users Equipment (UE); (ii) cross-link interference between cells that use different schemes. The 3GPP standard neither specifies algorithms or solutions derive configuration nor solves...

The deployment of 5G and 6G is highly motivated by the emerging network services that demand more band-width very low latency. Besides, these are shifting from dominant Downlink (DL) Traffic to a equilibrate DL/UpLink (UL) UL traffic for specific services. One option accommodate this new behavior use Time Duplex Division (TDD), where radio frame shared between DL time slots, namely UL/DL pattern. While 4G TDD has fixed number configurations cannot be updated on runtime, 5GNR allows complete...

With its low latency and high speeds, 5G aims to support vertical services like automotive, industry, agriculture, manufacturing. Unlike the precedent mobile generations, which just provided voice data domestic business customers, create a common infrastructure diverse requirements of industry's needs in terms communication networking capabilities, such as rate latency. But before commercial deployment, trial phase is needed validate that network can these requirements. In this context,...

5G networks and beyond are shifting from dominant Downlink (DL) traffic to a more equilibrate DL/UpLink (UL) UL for specific emerging services. Particularly ultra-Reliable Low Latency Communications (uRLLC) services, the latency becomes an essential factor consider. However, current scheduling methods not efficient in terms of Physical Resource Blocks (PRBs) allocation, latency, or link adaptation. In this paper, we address challenge related beyond. We introduce solution based on Deep...

The network conditions experienced by end-users of a cellular can greatly vary over time because changing coverage, due to the end-user's mobility, interference, or highly loaded cells at peak hours. Adaptive BitRate (ABR) streaming compensate for some these difficult having video player requesting lower bitrates. However, in best case, this comes price quality and, worst, may still lead freezes and rebuffering.

The mobile industry - via forums such as the O-RAN Alliance and Linux Foundation CAMARA is working on network APIs that allow a operator to expose capabilities application developers. One of these Quality Demand (QoD) API, which enables ask for additional resources improved latency or bandwidth. In this work, we show how an intelligent content delivery (CDN) can exploit improve quality experience (QoE) video streaming despite difficult conditions by boosting available bandwidth at precise...

Future generation cellular networks consider Power Consumption (PC) as a key concern in designing and operating wireless communication systems. In this context, 3GPP has proposed several techniques to reduce User Equipment (UE) PC, such Connected-mode Discontinuous Reception (C-DRX), with new set of parameters introduced by 5G New Radio (NR) BandWidth Part (BWP) adaptation. However, they did not specify how derive the C-DRX BWP configuration that PC while avoiding latency overflow. To...
