This paper presents DISC, a dataset of millimeter-wave channel impulse response measurements for integrated human activity sensing and communication. This is the first dataset collected with a software-defined radio testbed that transmits 60 GHz IEEE 802-11ay-compliant packets and estimates the channel response including scattered signals off the moving body parts of subjects moving in an indoor environment. The provided data consists of three parts, for more than 2 hours of channel measurements with high temporal resolution (0.27 ms inter-packet time). DISC contains the contribution of 7 subjects performing 5 different activities, and includes data collected from two distinct environments. Unlike available radar-based millimeter-wave sensing datasets, our measurements are collected using uniform packet transmission times and sparse traffic patterns from real Wi-Fi deployments. We develop, train, and release open-source baseline algorithms based on DISC to perform human sensing tasks. Our results demonstrate that DISC can serve as a multi-purpose benchmarking tool for machine learning-based human activity recognition, radio frequency gait analysis, and sparse sensing algorithms for next-generation integrated sensing and communications.

LoS sensing-based superimposed CSI feedback for UAV-Assisted mmWave systems
在无人机辅助毫米波系统中，信道状态信息（CSI）反馈对于调制方案的选择、资源管理、波束形成等至关重要。然而，传统的CSI反馈方法会导致UAV发射机的显著反馈开销和能量消耗，从而缩短系统的运行时间。为了解决这些问题，受叠加反馈和通感一体化（ISAC）的启发，提出了一种基于视距（LoS）传感的叠加CSI反馈方案。具体地，在UAV发射器侧，地面到UAV（G2 U）CSI叠加在UAV到地面（U2 G）数据上以反馈到地面基站（gBS）。在gBS处，专用LoS感测网络（LoSSenNet）被设计为在LoS和NLoS场景中感测U2 G CSI。利用LoS-SenNet的感测结果，从初始特征提取中确定的G2 U CSI将用作先验信息以指导后续操作。具体地，对于NLoS中的G2 U CSI，开发CSI恢复网络（CSI-RecNet）和叠加干扰消除以恢复G2 U CSI和U2 G数据。对于LoS场景，在CSI-RecNet和叠加干扰消除块之前嵌入专用LoS辅助网络（LoS-AidNet），以突出G2 U CSI的特征。仿真结果表明，与其他叠加CSI反馈方法相比，该反馈方案有效地提高了G2 U CSI和U2 G数据的恢复精度。此外，对参数变化，所提出的反馈方案显示其鲁棒性。
