Speech Title: Analysis of Offshore
Propagation Characteristics of Oscillating Magnet based Mechanical Antenna
Abstract: The offshore surface propagation characteristics of an Oscillating Magnet Based Mechanical Antenna (OMBMA) is analyzed in this paper. The equivalent oscillating magnetic dipole model of OMBMA is analyzed, and the Sommerfeld expression of the electromagnetic radiation field of the vibration magnetic dipole is given. The semi-infinite two-layer dielectric propagation model of the horizontal vibration magnetic source under the sea surface is established. The propagation path of the electromagnetic field and the field strength at the receiving point are analyzed theoretically. Finally, the propagation characteristics of OMBMA with the operating frequency of 1000Hz near the sea surface are verified by simulation. It is found that when the sum of the depth of the receiving point and the source point is fixed, the attenuation characteristics of the radiation field intensity are the same at different depths of the source point or the receiving point. When the distance between the receiving and the source points exceeds a certain horizontal distance, the magnetic field intensity at the receiving point will decrease rapidly.

Speech Title: Energy-Age Tradeoff for Status Update
Abstract: Age-of-Information (AoI), or simply age, which measures the data freshness, is essential for real-time Internet-of-Things (IoT) applications. On the other hand, energy saving is urgently required by many energy-constrained IoT devices. This work studies the energy-age tradeoff for status update from a sensor to a monitor over an error-prone channel. The sensor can sleep, sense and transmit a new update, or retransmit by considering both sensing energy and transmit energy. An infinite-horizon average cost problem is formulated as a Markov decision process (MDP) with the objective of minimizing the weighted sum of average AoI and average energy consumption. By solving the associated discounted cost problem and analyzing the Markov chain under the optimal policy, we prove that there exists a threshold optimal stationary policy with only two thresholds, i.e., one threshold on the AoI at the transmitter (AoIT) and the other on the AoI at the receiver (AoIR). Moreover, the two thresholds can be efficiently found by a line search. Numerical results show the performance of the optimal policies and the tradeoff curves with different parameters. Comparisons with the conventional policies show that considering sensing energy is of significant impact on the policy design, and introducing sleep mode greatly expands the tradeoff range.

Speech Title: Resource Scheduling for NOMA-based Mobile
Phones and IoT Fusion Satellite Network
Abstract: With the advent of 5G, wireless communication has greatly changed people's lifestyles. However, limited by the coverage of terrestrial cellular networks, the demand for communication services of mobile phones in remote areas is difficult to be met. In order to meet the large coverage and quality of service (QoS) requirements of mobile phones, we consider a non-orthogonal multiple access (NOMA)-based mobile phones and internet of things (IoT) fusion satellite network. In this network, low earth orbit (LEO) satellite can significantly enlarge the coverage while NOMA and IoT further improve the utilization efficiency of resources. Aiming at maximizing the QoS satisfaction rate of mobile phones and the sum rate of internet of things devices, we formulate a joint optimization problem considering NOMA user grouping, inter-group power allocation and intra-group power allocation. To tackle the problem, we design a QoS priority joint optimization algorithm based on proximal policy optimization (Q-PPO). The experimental results show that the proposed Q-PPO algorithm always has considerable performance in QoS satisfaction rate and sum rate of internet of things devices.

Speech Title: Nonlinear Precoding for Mobile
Phone-Satellite direct connection under Non-Terrestrial Network
Abstract: The Global communications ecosystem believes satellite-based communications to be an important part of 5G-Advanced and 6G. The 3rd Generation partnership project (3GPP) has officially started researching on integrating satellite communications with 5G new Radio (NR) techniques titled “non-terrestrial network”. Multi-beam mobile satellite system has a great potential in providing broadband mobile services over a large area to achieve a high system throughput, which is considered as a typical communication scenario in 3GPP NTN. Whenever multibeam satellite systems target to very aggressive frequency reuse in their coverage area, inter-beam interference becomes the major obstacle for increasing the overall system throughput. In this talk, we will introduce the nonlinear precoding technology as one of the most potential solutions to the interference mitigation problem in NTN. The discussion include: the linear and non-linear precoding technologies comparison, a novel nonlinear algorithm named List encoding of Vector Perturbation Precoding (LVP) we have developed for NTN mobile phone-satellite direct connect communication，and also some progress we have made recently in hardware testbed implementation.

Speech Title: End-to-end Delay in TSN-aided Integrated
Sensing and Communication Networks: An Analysis Framework
Abstract: In this report, we provide a spatial-temporal analysis framework for large-scale distributed TSN aided Integrated Sensing and Communication network （ISAC）. Delay-sensitive sensing tasks, which may also be stochastic and entangled with communications, can be randomly performed in a large area and then the data are wirelessly collected and then delivered to the datacenter/processors via Time Sensitive Networks (TSN). While the TSN can provide latency bound data transmitting services via i.e., IEEE 802.1 Qbv gate-controlled mechanism, the end-to-end delay violation probability is mainly decided by the random sensing and wireless communication process. However, the fluctuating wireless channel environment and indescribable spatial distribution of sensing devices make it hard to characterize and guarantee the end-to-end quality of service requirements even stochastically. We will introduce a framework to analyze the delay upper bound for the integrated wireless-TSN via stochastic network calculus approach. Specifically, Poisson cluster process is utilized to capture the spatial distribution of data gathering centers and wireless sensing and forwarding devices, and to derive the Laplace transform of interference suffered by the data gatherer device of interest. The end-to-end upper bounds for the delay violation probability are established by exploiting SNC with the Mellin transform of signal-to-interference ratio. This work can be a guidance framework for modeling and analysis of large-scale integrated networks, such as large scale industrial networks.

Speech Title: Resource allocation based on deep
reinforcement learning for LEO beam-hopping system
Abstract: This speech introduces a resource allocation algorithm based on deep reinforcement learning for LEO beam-hopping system. Firstly, an optimization problem with the goal of minimizing the queuing delay of data packets is established. Then LEO satellite is modeled as an intelligent agent, reads the data packet on board buffer state for each beam position. After state reconstruction, a DQN network is designed to train data. Finally, the intelligent agent formulates a beam-hopping resource allocation plan. The simulation results show that, compared with traditional methods, the resource allocation algorithm based on deep reinforcement learning can reduce the queuing delay of data packets and improve the system throughput, and can adapt to the uneven distribution of traffic.
