Abstract
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.
期刊介绍：
IEEE Wireless Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of wireless communications. 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 wireless communication systems.
