Transit signal priority (TSP) is an effective strategy to enhance the operational efficiency of buses and increase bus ridership. Nonetheless, existing TSP strategies seldom utilize connected information to control buses collaboratively and take safety into consideration. In this paper, we propose a method that combines signal timing optimization with longitudinal control of Connected and Autonomous Vehicles (CAVs) to improve efficiency and comfort for passengers while ensuring safety. This method modifies signal timing at isolated intersections to prioritize buses as well as controls the delayed CAV bus to catch the green light smoothly and cooperatively change lanes based on Vehicle-to-Everything (V2X) communication. Moreover, the Control Barrier Functions are used as safety-critical constraints in Model Predictive Control to avoid collisions. The effectiveness of the proposed method is evaluated in comparative analyses against controllers without TSP or longitudinal control in CARLA. The simulation results reveal that the proposed method reduces waiting time at intersections and velocity fluctuations while maintaining a safe following distance.

With the rapid development of 5th Generation Mobile Communication Technology (5G), the increased bandwidth not only bolsters communication efficiency but also paves the way for high-precision location-based services within these industrial applications. Positioning by using a single base station (BS) possesses potential vital values in scenarios that multiple BSs are not applicable, such as unmanned aerial vehicle assisted emergency communication scenarios, dynamic and temporary industrial 5G scenarios, etc. However, due to a lack of observed measurements from different base stations, the high accurate and stable positioning by using a single BS faces challenges. To address this problem, this paper introduces a novel approach utilizing the open-source 5G platform OpenAirInterface (OAI) to design application programming interfaces (APIs) for accessing low layer data. By extracting data directly from actual protocol stacks, we have developed a multidimensional data fusion localization system based on Vision Transformer (ViT) in a single-BS mode named FLIT. Conducted within an office setting, our experiments spanned a 100MHz bandwidth, culminating in a system capable of achieving an average positioning error of just 6.9cm, with 90% of measurements within a 9cm error margin and 80% within 5.3cm, thus attaining centimeter-level accuracy in positioning.

This paper studies an integrated sensing and communication (ISAC) system with movable antennas (MAs), where the position of antennas can be flexibly adjusted to reshape the wireless channel. We aim at jointly optimizing the positions of MAs, beamforming of the communication signal, and the covariance of the sensing signal to maximize the overall transmit beampattern gain while ensuring the quality of communication service requirement. Considering the non-convexity of this optimization problem, we propose an efficient algorithm to obtain a high-quality solution by using alternating optimization, semi-definite relaxation (SDR) and Taylors theorem. The simulation results show that the proposed algorithm significantly improves the beampattern gain.

This paper studies a multi-user integrated sensing and communication (ISAC) system with delay alignment modulation (DAM) in the near-field. We aim to optimize multi-path hybrid beamforming so as to maximize the signal-to-noise ratio (SNR) of the target echo while ensuring communication users' signal-to-interference plus-noise ratio (SINR) requirements and transmit power budget. To this end, we propose an alternating optimization algorithm using successive convex approximation (SCA) technology, penalty convex-concave procedure (PCCP) and second-order cone programming (SOCP). Simulation results demonstrate the effectiveness of the proposed algorithm and show the impact of channel model mismatch and the distance dimension introduced by the near-field model on the near-field DAM-ISAC system.

Generation (5G) mobile communication provides high-resolution measurements of delays and angles, which make radio simultaneous localization and mapping (SLAM) a possibility. Current radio SLAM systems focus on static environments. However, moving objects may degrade the performance of SLAM systems. In this paper, we propose an integrated radio SLAM and moving object tracking scheme for dynamic environments. Specifically, we first use a grid-based object detection method to detect and filter out measurements belonging to the multipath components (MPCs) of moving objects for accurate radio SLAM. After obtaining the precise vehicle position via SLAM, a curve fitting method is used to track and predict the trajectories of the moving objects, and the prediction results will help in the detection of the object at the next moment. Finally, simulation results demonstrate the performance of the proposed scheme.

Comprehensive coverage is a natural advantage of satellites, and loading the functions of base station on satellites can expand the service range of Satellite-Terrestrial Integrated network(STIN), providing users with extensive and efficient access services. However, the management and control capabilities of satellite networks are inadequate, and this aspect has not been well investigated. The signalling from the control plane needs to be routed over the backhaul links to the Terrestrial Core network(TCN) for processing which increases the service latency. In this paper, we propose a novel integrated core network architecture where satellites simultaneously have access and control capabilities by provisioning next-generation NodeB(gNB) and some core network functions. Considering the constrained satellite resources, we design a lightweight Stateless Satellite Core network (SSCN) to enhance the flexibility and stability of the satellite network control. Meanwhile, based on SSCN, we redesign the registration, session establishment, and handover procedures to support mobility management and further reduce service latency. Simulation results show that the proposed integrated core network architecture improves the stability of mobility management and optimizes the network latency compared to the Non-Terrestrial network(NTN) architecture in that satellites act as radio access networks only.

As a novel communication paradigm to achieve efficient end-to-end communication over wireless channels, deep learning (DL) enabled semantic communication system has attracted increasing attention. However, semantic wireless communication systems are affected by multi-dimensional noise, including physical channel noise and semantic noise caused by unstable sources in the real environment. Unfortunately, the joint consideration of physical channel noise and visual semantic noise in video semantic transmission has not been studied yet in the current literature. In this paper, we propose a novel DL-enabled video semantic communication system called DVSC, which employs channel and spatial attention mechanisms to achieve self-adaptation for different channel conditions, mitigating the impacts of varying degrees of physical channel noise on system performance. Additionally, we introduce a feature refinement module based on an encoder-decoder architecture, and a semantic correction module based on a lightweight U-Net structure, which can address semantic ambiguity caused by visual semantic noise at the transceiver. We also design a loss function that considers both pixel and perceptual quality metrics to jointly optimize the DVSC in the pixel and semantic domains. Our extensive experimental results demonstrate that the DVSC can adapt to various channel conditions and outperform benchmark comparison schemes while spending less time on encoding and decoding. To reproduce our results, we make the source code publicly available at https://***/Coding-Cow/***.

This paper investigates the Joint Optimization of Base station sleeping, Functional split, and Routing selection (JOBFR) in virtualized radio access network (vRAN) architectures to minimize the operator’s total cost, including operating cost and migration cost while satisfying user requirements. Specifically, we first use mathematical methods to describe the relationships between the base station (BS) sleeping, functional split (FS) and routing selection, and then model the goal as a joint optimization problem. Next, we propose a heuristic algorithm called Flexible Sleeping, Functional split, and Routing selection (FSFR) to decide BS sleeping, and FS option, and routing selection, simultaneously. Finally, we perform extensive simulations to evaluate our algorithm. The results demonstrate that our algorithm can significantly save the total cost of operators compared to the baseline approach and can also achieve near-optimal performance.

Although satellite backhauls facilitate expanding network coverage and providing capacity in unconnected areas, delivering high-quality videos via satellite backhauls is challenging due to high delay, bandwidth limitations and high expenses. Super-resolution (SR) technique has been proposed to integrate into streaming systems to improve Quality of Experience (QoE) in bandwidth-limited environments. However, existing SR-enhanced streaming systems face two key challenges: 1) compatibility problem that legacy video servers and user equipment (UEs) must be modified to integrate SR-related modules, and 2) quality consistency problem that enhanced video quality fluctuates across chunks. Motivated by this, we present SatOL, a novel SR-enhanced video streaming system for satellite-backhauled networks. Specifically, SatOL is designed on a cloud-edge cooperation framework, where a cloud server and an edge server are responsible for SR model training and SR-based video enhancement, respectively. This framework operates as an intermediate hop within end-to-end streaming sessions to perform SR-related processing, avoiding modifications to legacy video servers and UEs. Instead of training video-tailored SR models offline, the cloud server continually trains chunk-tailored SR models during video streaming, which are overfitted to corresponding chunks and provide consistent quality enhancement. To avoid rebuffering caused by time-consuming model training, an online fine-tuning method is proposed to significantly expedite SR model training. To further improve online training efficiency, we propose a decision mechanism that determines whether and how to train chunk-tailored SR models based on the chunks' 1-frame count. Evaluations show that SatOL outperforms baselines, improving QoE and enhanced video quality by 6-285% and 17-25%, respectively, while reducing bandwidth usage by 60-64%.

Augmented reality (AR) technology is increasingly applied in the Internet of vehicles (IoV). As it poses significant challenges to the communication and computation capabilities of AR terminal devices, this paper investigates combining terahertz (THz) and mobile edge computing (MEC) integrated with reinforcement learning (RL) to optimize the performance of AR services for the IoV. Though the RL-based MEC offloading has been validated to have excellent performance, it has an intrinsic disadvantage where its training phase needs inappropriate offloading strategies to be tested frequently and poses risks to safe driving. Moreover, although THz communication can provide high transmission data rates, its characteristics that different transmission distances lead to different available bandwidth, pose a unique challenge for the communication resources allocation. Motivated by these, we propose a novel static data-driven AR tasks offloading framework to solve resources allocation problem for the IoV with THz communication. To deal with the challenge that different users have different available THz bandwidth, we propose a distance-aware fair THz bandwidth allocation algorithm. Moreover, the offline RL, instead of online RL, is utilized to train the AR task offloading decision agent, where interaction with the real world is not required, completely safeguarding the system's safety. To address the typical issue of out-of-distribution (ODD) actions encountered in offline RL, we adopt conservative Q-learning (CQL) to train and obtain the optimal AR computation task offloading strategy to enhance users' experience. Simulation results show that the proposed solution outperforms state-of-the-art algorithms in terms of algorithm stability and user reward.
