Power efficiency is a critical metric for a sustainable 6G network. The emergence of integrated sensing and communication (ISAC) services leads to significant power consumption due to additional signal transmission for sensing. An ISAC beamforming is an efficient transmission method for reducing power consumption in mmWave multi-input multi-output (MIMO) systems while meeting the requirements of communication users (CUs) and sensing users (SUs). This approach is only feasible when both users are within the coverage of the same beam. Otherwise, separate beams are required which results in high power consumption. In this letter, we propose a novel time-domain scheduling method for ISAC beamforming to achieve high-power efficiency. The performance gains compared to conventional scheduling method are demonstrated for the different number of users, periodicity values, and user distribution ratios.

用于 ISAC 波束成形的高能效时域调度


电源效率是可持续 6G 网络的关键指标。集成传感和通信 （ISAC） 服务的出现导致了大量的电力消耗，因为传感需要额外的信号传输。ISAC 波束成形是一种高效的传输方法，可降低毫米波多输入多输出 （MIMO） 系统的功耗，同时满足通信用户 （CU） 和传感用户 （SU） 的要求。仅当两个用户都在同一波束的覆盖范围内时，此方法才可行。否则，需要单独的光束，这会导致高功耗。在本文中，我们提出了一种新的 ISAC 波束成形时域调度方法，以实现高功率效率。针对不同的用户数、周期性值和用户分布比率，演示了与传统调度方法相比的性能提升。
