The current literature on 6G O-RAN primarily addresses improved mobile broadband (eMBB) performance or URLLC latency optimization individually, often neglecting the intricate balance required to optimize both simultaneously under practical constraints. This paper addresses this gap by proposing a DRL-based resource allocation framework integrated with meta-learning to manage eMBB and URLLC services adaptively. Our approach efficiently allocates heterogeneous network resources, aiming to maximize energy efficiency (EE) while minimizing URLLC latency, even under varying environmental conditions. We highlight the critical importance of accurately estimating the traffic distribution flow in the multi-connectivity (MC) scenario, as its uncertainty can significantly degrade EE. The proposed framework demonstrates superior adaptability across different path loss models, outperforming traditional methods and paving the way for more resilient and efficient 6G networks.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"5 ","pages":"7701-7714"},"PeriodicalIF":6.3,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10772596","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We take note that to develop a low-complexity detector one should first obtain a list of candidate samples of the transmitted data symbols that closely match with the received signal. Here, for the list generation, we expand on a recently proposed stochastic sampling method. Two methods are developed and demonstrated. The first method, called single list stochastic list generator (SL-SLG), generates a list at the first iteration of the turbo loop, i.e., without the benefit of any a priori knowledge, and used throughout the iterative detection process. The second method, called update list stochastic list generator (UL-SLG), updates the list after each iteration using the a priori information provided by the channel decoder. The effectiveness of these stochastically generated lists are benchmarked against the celebrated method of K-best. Extensive computer simulations, using real-world MIMO channels, reveal that the proposed method outperforms the K-best method, when the system parameters are set for the same list size. It is also noted that whereas the list generation method in K-best follows a sequential approach, the stochastic sampling method proposed in this paper is tailored towards a parallel implementation, which, helps in reducing the detector latency significantly.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"6 ","pages":"452-465"},"PeriodicalIF":6.3,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10772643","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142938172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a set of measurements of ultrawideband (UWB) channels of such a BAN when the user is in an indoor office environment. Based on this, we derive a novel model for link gain as a function of the location of the device on the body. This model distinguishes the power received via (i) on-body propagation, (ii) reflections from close-by objects, and (iii) reflections from other parts of the environment. For the on-body and near-by object reflections, we further introduce a new model for the link gain that depends on both the Euclidean distance and the azimuthal positions of the RX antenna elements on the circumference of the body. The measurements and derived models are first motivated by measurements on an RF phantom.

In this paper, the joint orchestration of O-RAN and MEC using a Bayesian deep reinforcement learning (RL) framework is proposed. The framework jointly controls the O-RAN functional splits, O-RAN/MEC computing resource allocation, hosting locations, and data flow routing across geo-distributed platforms. The goal is to minimize the long-term total network operation cost and maximize MEC performance criterion while adapting to varying demands and resource availability. This orchestration problem is formulated as a Markov decision process (MDP). However, finding the exact model of the underlying O-RAN/MEC system is impractical since the system shares the same resources, serves heterogeneous demands, and its parameters have non-trivial relationships. Moreover, the formulated MDP results in a large state space with multidimensional discrete actions. To address these challenges, a model-free RL agent based on a combination of Double Deep Q-network (DDQN) with action branching is proposed. Furthermore, an efficient exploration-exploitation strategy under a Bayesian learning framework is leveraged to improve learning performance and expedite convergence. Trace-driven simulations are performed using an O-RAN-compliant model. The results show that our approach is data-efficient (i.e., converges significantly faster), increases the reward by 32% compared to its non-Bayesian version, and outperforms Deep Deterministic Policy Gradient by up to 41%.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"5 ","pages":"7685-7700"},"PeriodicalIF":6.3,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10771978","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the natural graph structure of the satellite network, we innovatively integrate the graph neural network (GNN) into the MARL algorithm to form a GNN-assisted MARL framework, wherein GNN can capture the enriched semantic information present in satellite topology to achieve the fusion of diverse environmental states, which is beneficial for improving the decision-making effectiveness of agents.

To solve this problem, we propose a hybrid algorithm, which consists of simulated annealing (SA) algorithm and Dueling Double Deep Q Network (D3QN) algorithm.

On this basis, the D3QN algorithm is used to optimize the flight trajectory of the energy-limited inspection AAV. To prove the effectiveness of the sub-optimal solution obtained by our proposed algorithm, we use several algorithms as a comparison.

First, we analyze the performance of the CUMA network in terms of the outage probability (OP) and the ergodic rate (ER), deriving simple and highly accurate closed-form approximations of the channel statistics. Then, we evaluate the potential of the CUMA scheme to provide secure multi-user communications from a physical layer security perspective. Leveraging a tight approximation to the signal-to-interference-ratio (SIR) distribution, we derive closed-form expressions for the secrecy outage probability (SOP). We observe that the baseline CUMA (without side information processing) exhibits limited performance when eavesdroppers are equipped with a CUMA of the same type. To improve their secure performance, we suggest that a simple imperfect interference cancelation mechanism at the legitimate receiver may substantially increase the secrecy performance.

Optical inter-satellite links provide high data rates, long-range, and robustness against interferences, and they do not require frequency licensing as radiofrequency communication systems. Nevertheless, as the uncertain location of the receiver is comprised in an area larger than that illuminated by the transmitting laser, the pointing accuracy is a critical element in the success of the optical link establishment and maintenance, requiring a pointing, acquisition, and tracking mechanism. The acquisition process is the most time-consuming of the pointing processes, limiting the time available to send data, especially in highly dynamic networks. This paper focuses on reducing the acquisition time by reducing the initial satellite position uncertainty. To this end, a hybrid system that combines RF and optical technologies in a single communication module is proposed. Whereas the control plane is managed via the RF link to exchange more precise global navigation data, the optical link corresponds to the data plane in which payload data is exchanged. The pointing between two satellites is simulated to analyze its behavior, considering the error of cumulative orbital propagation data and global navigation satellite system data. This work also analyzes the cumulative error produced by the propagation of the TLEs over time. Finally, the results show how a system that relies on the exchange of global navigation satellite system positioning data achieves up to 99.45% better-pointing accuracy than a system that bases positioning data on TLE propagation.","PeriodicalId":33803,"journal":{"name":"IEEE Open Journal of the Communications Society","volume":"5 ","pages":"7598-7612"},"PeriodicalIF":6.3,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10769552","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
