集成感知、通信与计算(ISCC)为室内以人为中心的应用提供了前景广阔的框架。在此类应用中,短期人体姿态预测有助于实现连续的人体追踪与提前资源分配。本文提出一种基于克拉美罗界(CRB)的资源分配框架,用于最小化室内毫米波ISCC系统中的人体姿态预测误差,同时满足通信、时延与能量约束。我们基于CRB分析了感知功率对距离估计不确定性及点云扰动的影响。为捕捉计算资源对预测性能的影响,采用自适应深度的Mamba姿态预测模型,在每一层后附加轻量级预测头,支持不同模型深度的推理。通过统一的感知-计算建模,建立了感知功率、模型深度与预测误差之间的定量关系。进一步地,构建联合资源分配问题以最小化预测误差。为高效求解,提出基于交替优化(AO)的算法,并推导出感知功率与模型深度更新步骤的闭式解。仿真结果表明,所提方案相比基线方法显著降低了姿态预测误差,验证了其在资源受限的室内人机交互ISCC系统中的有效性。

原文摘要 · Abstract (English)

Integrated sensing, communication, and computation (ISCC) provides a promising framework for indoor human-centric applications. In these applications, short-term human pose prediction facilitates continuous human tracking and resource allocation in advance. In this paper, we propose a Cramer-Rao bound (CRB) guided resource allocation framework for indoor mmWave ISCC systems to minimize the human pose prediction error under communication, latency, and energy constraints. We characterize the impact of sensing power on range-estimation uncertainty and point-cloud perturbation based on the CRB. To capture the impact of computation resources on prediction performance, we adopt an adaptive-depth Mamba-based pose prediction model, where lightweight prediction heads are attached after every layer to enable inference with different model depths. With this unified sensing-computation modeling, we establish a quantitative relationship among sensing power, model depth, and prediction error. Furthermore, we formulate a joint resource allocation problem to minimize the pose prediction error. To solve this problem efficiently, we develop an alternating optimization (AO)-based algorithm, where closed-form solutions are derived for the sensing power and model depth update steps. Simulation results show that the proposed scheme significantly reduces pose prediction error compared with baseline methods, validating its effectiveness for resource-constrained indoor human-centric ISCC systems.
