Scalable Distributed User Scheduling for Low-Altitude Wideband Cell-Free RAN

Pengzhe Xin, Yue Wu, Tianjiao Zhang, Yanfeng Hu et autres

This paper investigates scalable user scheduling in low-altitude, wideband cell-free radio access networks (CF-RANs), where scheduling is decentralized to user-centric distributed units (UCDUs), enabling scalable medium access control (MAC)-layer operation. Firstly, to provide analytical insights into the impact of distributed nature of …

Hierarchical Computing Architecture for mURLLC in Cell-Free Systems: Load Computation, Demand Mapping, and Resource Allocation

Yuantao Lv, Jie Wang, Jiamin Li, Pengcheng Zhu et autres

With the rapid growth of time-sensitive services, existing infrastructures struggle to guarantee large-scale millisecond-level latency and high reliability. To meet these demands, massive ultra-reliable and low-latency communication (mURLLC) has been introduced as a core scenario in sixth-generation (6G) networks. To address the …

Performance Analysis of Spatiotemporal 2-D Polar Codes for Massive MIMO With MMSE Receivers

Yaqi Li, Xiaohu You, Jiamin Li, Chen Ji et autres

With the evolution from 5G to 6G, ultra-reliable low-latency communication (URLLC) faces increasingly stringent performance requirements. Lower latency constraints demand shorter channel codeword length, which can severely degrade decoding performance. The massive multiple-input multiple-output (MIMO) system is considered a crucial technology to …

Grant-Free NOMA in Cell-Free Massive MIMO Over Universal Filtered Multicarrier for mURLLC

Changju Chen, Jiamin Li, D P Wang, Pengcheng Zhu

This paper investigates grant-free non-orthogonal multiple access (NOMA) in cell-free massive multiple-input multiple-output networks over universal filtered multicarrier (UFMC) for massive ultra-reliable low-latency communication (mURLLC). We identify that the even-component of the frequency domain (FD) received signal is free from both inter-sub-band …
