To this end, we propose ISACoT as the framework for enabling Integrated Sensing and Communication (ISAC) over IoT devices. ISACoT extends over existing devices via four aspects, namely time, frequency, space, and protocol. We argue that, as the multistatic communication infrastructure of IoT is adverse to device-free sensing (e.g., lack of precise time synchronization), the keystone of ISACoT should be to operate sensing in a monostatic mode (like radar). We tackle the fundamental time aspect based on Wi-Fi first, then explore the other three aspects with both preliminary proposals made and potential challenges raised for future extensions.","PeriodicalId":203933,"journal":{"name":"Proceedings of the 1st ACM MobiCom Workshop on Integrated Sensing and Communications Systems","volume":"2 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128781412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing methods mainly include waveform design without Reconfigurable Intelligent Surface (RIS) or the sensing-based waveform design with RIS, which usually degrade the comprehensive performance. To address this issue, the comprehensive waveform design with RIS is proposed, where we jointly maximizing the Signal-to-Interference-and-Noise-Ratio (SINR) for radar and minimizing the RIS-aided Multiple User Interference (MUI). Due to the coupling effect between the phase shifts and waveform, the problem is difficult to solve. Additionally, the CM constraint on both the phase shifts and waveform along with the fractional SINR expression further aggravate the difficulty. To address these issues, a Decoupled Online Learning Network (DOL-Net) method is proposed using the characteristic of multiple input to multiple output mapping, which includes trainable network parameters module, loss calculation module and back-propagation module. Given fixed network parameters, the cost function can be calculated in the loss calculation module. Then, the network parameters are trained by the deep learning optimizer to minimize the loss function. Compared with the existing methods, the proposed method obtains 0.69 dB radar SINR enhancement and 138.8 % communication sum rate improvement.","PeriodicalId":203933,"journal":{"name":"Proceedings of the 1st ACM MobiCom Workshop on Integrated Sensing and Communications Systems","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132985392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, to improve the performance of the NUBPM-enabled ISAC systems, we investigate the beam pattern set design and activation probability optimization. Simulation results show that the proposed scheme considerably outperforms existing ISAC designs in spectral efficiency while keeping the same sensing performance.

In this paper, we propose to design the ISAC system by jointly considering radar sensing and ultra-reliable low-latency communication (URLLC), which needs a joint precoding design for radar and URLLC. Then, we formulate a transmit power minimization problem by jointly considering the performance requirements of radar sensing and latency in URLLC. By using approximation method and quadratic transform based fractional programming method, the optimization problem can be efficiently solved.

Despite the promising performance of ISAC, the power supply of million of radar sensors distributed in remote or even dangerous areas has not been resolved yet. To tackle this problem, wireless power transfer (WPT) is expected to enable the wirelessly powered ISAC, where the edge nodes equipped with multiple antennas are powered by the beacon and then perform ISAC. To improve the sensing accuracy while guaranteeing the communication throughput, the power control, WPT energy beamforming, and ISAC beamforming are jointly optimized, which results in a non-convex problem. To derive a practical solution, the semi-definite relaxation together with the properties for achieving the optimum are exploited.

However, in the autonomous driving scenario, a fast and robust beam tracking algorithm is needed to ensure the quality of communication. We propose a sensing information assisted mmWave beam tracking algorithm combining both camera and light detection and ranging (LiDAR). The beam misalignment problem of the camera in the case of insufficient ambient light is solved and the robustness of the beam tracking algorithm is enhanced. The proposed algorithm in this paper is validated by the joint sensing and communication hardware platform in the mmWave frequency band, which can guarantee the high data rate communication performance regardless of sufficient and insufficient ambient light under the mobility scenarios.","PeriodicalId":203933,"journal":{"name":"Proceedings of the 1st ACM MobiCom Workshop on Integrated Sensing and Communications Systems","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116223040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we formulate the joint design problem as optimizing the spectrum efficiency (SE) of communication and the signal-to-interference noise ratio (SINR) of radar sensing. Due to the coupling between the digital and analog beamformers in the hybrid beamforming structure, the resultant problem is NP-hard. Towards this end, a consensus alternating direction method of multipliers (CADMM) approach is developed, by decoupling the digital precoder and the analog precoder with auxiliary variables. In each iteration, the digital precoder can be analytically obtained, while the analog precoder is designed via a phase-only beamforming method. Both the communication and radar receivers are optimized through the generalized eigenvalue decomposition. Numerical simulations are provided to demonstrate the effectiveness of the proposed design approach.","PeriodicalId":203933,"journal":{"name":"Proceedings of the 1st ACM MobiCom Workshop on Integrated Sensing and Communications Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130579040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Device-free sensing with machine learning mechanisms enable detection, recognition automatically, without required explicit programming. Because of concern of indoor sensing privacy and ubiquitous sensing ability, it is really necessary to conduct an in-depth survey on device-free sensing security training and cross-domain sensing issues. Existing surveys have two important problems: weak robustness and low efficiency. To address them, this article put forward to learn domain independent features, model training and inference localization based on federated transfer learning. Moreover, several efficient methods are proposed to provide a distributed edge device-free sensing mechanism with sensing data privacy protection, low time cost, communication, computing and energy resources. We implement the proposed mechanism and carry out experiments with Widar3.0 datasets to evaluate its performance. The results demonstrate that our mechanism performs better for cross-domain device-free sensing while preserving user data privacy and saving resources.","PeriodicalId":203933,"journal":{"name":"Proceedings of the 1st ACM MobiCom Workshop on Integrated Sensing and Communications Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127654763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
