A Scalable Semi-Grant-Free Access Scheme in Cell-Free Massive MIMO System
Chenyu Zhang, Yutong Wu, Jie Wang, Jiamin Li et autres
Semi-grant-free (SGF) access is regarded as a promising technology for next-generation networks, effectively easing the tension between massive access caused by user growth and limited communication resources. However, how to achieve efficient resource utilization through effective pairing of grant-based (GB) users and …
