Texto completo da fonteDynamic Time Division Duplexing (DynTDD) is pivotal in 5th generation (5G) networks, adapting resources to diverse needs. It enhances Spectral Efficiency (SE) by dynamically allocating time slots for Uplink (UL) and Downlink (DL) transmissions based on traffic demand and channel conditions. This dynamic frequency allocation ensures efficient spectrum use and supports massive connectivity, low latency, and Quality-of-Service (QoS) requirements. Its role in carrier aggregation maximizes data rates and capacity, highlighting its importance in advanced wireless communication technologies.However, DynTDD faces a significant challenge: cross-link interference (CLI). CLI occurs when UL and DL transmissions share the same frequency bands, leading to interference.CLI comprises base station to base station (BS-to-BS) or downlink to uplink (DL-to-UL) interference and user equipment to user equipment (UE-to-UE) or uplink to downlink (UL-to-DL) interference. In DL-to-UL interference, DL transmissions spill into UL bands, degrading UL communication. Conversely, UL-to-DL interference occurs when UL transmissions interfere with DL reception.Effectively managing CLI is crucial for DynTDD's performance and reliability.This thesis aims to unleash the full potential of DynTDD by overcoming CLI challenges through rigorous analysis and innovative methodologies. The research not only advances DynTDD technology but also pioneers solutions applicable to various communication contexts, driving innovative interference alignment strategies across diverse scenarios.The study in this thesis is divided into multiple segments. The first part establishes the foundation with the problem definition and essential theoretical concepts. The second part delves into the conditions determining the feasibility of interference alignment. These conditions are expressed in terms of the problem dimension and establish the achievable Degree of Freedom (DoF), representing the number of data streams. It explores interference alignment in centralized scenarios, considering both full-rank and reduced-rank Multiple-Input Multiple-Output (MIMO) Interference Broadcast Multiple Access Channel-Interference Channel (IBMAC-IC), addressing real-world complexities. Additionally, it extends the exploration to a distributed scenario, providing a realistic understanding of communication complexities. The third part focuses on optimization techniques, specifically beamforming. It introduces Zero Forcing (ZF) beamforming for both DL and UL User Equipment (UE)s to align CLI in DynTDD systems. It emphasizes the impact of UE-to-UE interference and presents improvements brought by the Weighted Minimum Mean Square Error (WMMSE) algorithms. Furthermore, it explores power allocation optimization using the water-filling algorithm

Texto completo da fonteThe quality of communication in a wireless network is primarily determined by the wireless link signal quality expressed in term of signal to-interference-plus-noise ratio. The fact that better signal quality enhances the communication quality incites to look for states whereeach receiver connects to a transmitter providing it with the best signal quality. Using stochastic geometry and then extreme value theory,we obtain the distribution of the best signal quality, of the interference, and of the maximum signal strength in both bounded and unbounded path loss conditions. We then investigate temporal variations of wireless links, which are also essential to wireless networking, in terms of level crossings of a stationary process X(t). We prove that the length of an excursion of X(t) above a level γ→-∞ has an exponential distribution, and obtain results associated with the crossings of several levels. These results are then applied to mobility management in cellular networks. We focus on the handover measurement function, which differs from the handover decision-execution by identifying the best neighbouring cell to which a connection switching is to be decided and executed. This function has an important influence on the user's experience, though its operation has been questionable due to the complexity of combining control mechanisms. We firstly address this topic with an analytical approach for emerging macro cell and small cell networks, and then with a self-optimisation approach for neighbour cell lists used in today's cellular networks

Texto completo da fonteRNAs are involved in numerous biological processes and can adopt different secondary structures. Thanks to their properties, they are powerful biological tools for diverse applications, such as small interfering RNA (siRNA) for gene silencing. Modified RNAs have proven to be essential to improve their properties, and to facilitate the study of their biological and therapeutic functions.This manuscript reports the synthesis and properties of 2’-O-modified RNAs bearing disulfide-containing groups, sensitive to reductive environment.The first part describes the synthesis of siRNAs prodrugs bearing lipophilic benzyldithiomethyl groups. The thermal stability, the serum stability and the response to glutathione treatment of modified siRNAs are thoroughly investigated. The gene silencing and the gymnotic delivery of several siRNAs are assessed, and demonstrates promising results on Ewing’s sarcoma cell line.A second part concerns the co-delivery of siRNAs and a hydrophobic anti-cancer drug (doxorubicin) using a self-immolative spacer bearing disulfide bonds. The chemico-physical properties of these conjugates are determined and the recovery of native siRNA and doxorubicin in response to reductive treatment is highlighted.A third part presents the conjugation of RNAs to small molecules (sugars, coumarin, biotin, deoxycholic acid, glutathione) using disulfide linkages. The synthesis of the RNA conjugates and their release in reducing conditions are also demonstrated.The last part reports the synthesis and the impact of an intrastrand dimethylene disulfide bridge between 2’-O-positions of two adjacent nucleotides in an RNA duplex and in the loop of RNA hairpins. Then, the influence of this linkage on the folding of a biologically relevant RNA structure is reported. Finally, an application of a constrained hairpin as a fluorescent molecular beacon highlights its potential use in tools for understanding RNA folding and in probes for the detection of reducing reagents
