摘要

我们研究了集成传感和通信（ISAC）系统的联合接纳控制和离散相位多播波束成形设计，其中传感和通信功能具有不同的层次结构。具体来说，ISAC系统首先将资源分配给层次较高的功能，然后利用剩余的资源来支持层次较低的功能。该资源分配问题是一个非凸混合整数非线性规划问题。我们提出了一个精确的混合整数线性规划（MILP）重新表述，导致全局最优解。此外，我们实现了三个基线进行比较，我们提出的方法优于39%以上。

Hierarchical Functionality Prioritization in Multicast ISAC: Optimal Admission Control and Discrete-Phase Beamforming

We investigate the joint admission control and discrete-phase multicast beamforming design for integrated sensing and commmunications (ISAC) systems, where sensing and communications functionalities have different hierarchies. Specifically, the ISAC system first allocates resources to the higher-hierarchy functionality and opportunistically uses the remaining resources to support the lower-hierarchy one. This resource allocation problem is a nonconvex mixed-integer nonlinear program (MINLP). We propose an exact mixed-integer linear program (MILP) reformulation, leading to a globally optimal solution. In addition, we implemented three baselines for comparison, which our proposed method outperforms by more than 39%.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
