Cell-Free Massive MIMO中没有小区,所有服务天线一致地为所有用户终端服务。 Cell-Free Massive MIMO目前只是一个新概念;它是MIMO与协作多点联合处理(Comp)的新实用且可扩展的版本。在某种程度上是基于良好传播和信道化化特性Massive MIMO技术的新应用。
Cell-free (CF) massive multiple-input multiple-output (MIMO) systems, which exploit many geographically distributed access points to coherently serve user equipment via spatial multiplexing on the same time-frequency resource, has become a vital component of the next-generation mobile communication ...
1Two-Timescale Transmission Design forRIS-Aided Cell-Free Massive MIMO SystemsJianxin Dai, Jin Ge, Kangda Zhi, Cunhua Pan, Zaichen Zhang, Jiangzhou Wang,Fellow, IEEE, and Xiaohu You, Fellow, IEEEAbstractThis paper investigates the performance of a two-timescale transmission design for uplink re...
One of the major technological breakthroughs to cope with these unprecedented demands is the cell-free (CF) massive multiple-input multiple-output (mMIMO) systems. In CF mMIMO, a large number of distributed access points are connected to a central processing unit, and serve a smaller number ...

Unlike the conventional cell-free massive MIMO-NOMA systems in which the UL signals from different access points are equally combined over the backhaul network, this paper develops an optimal backhaul combining (OBC) method to maximize the UL signal-to-interference-plus-noise ratio (SINR). With ...
Cell-Free 大规模 MIMO(Massive Multiple-Input Multiple-Output,Massive MIMO)通过部署成百上千个无线接入点(Access Points,APs),采用时分双工(Time Division Duplexing,TDD)操作模式,利用同一时频资源服务于所有用户(User Equipment,UE),并连接中央处理单元(Central Processing Unit,CPU)进行上下行用户传输和信号处理,...
Cell-Free (CF) mMIMO, which combines the best aspects of UDN and mMIMO, is viewed as a key solution to this issue. In such systems, each User Equipment (UE) is served by a preferred set of surrounding APs cooperatively. In this paper, we provide a survey of the state-of-the-art ...
