This chapter studies massive access in cell-free massive MIMO-based IoT systems and solves the challenging AUD and CE problems. For the uplink transmission, we propose an advanced frame structure design to reduce the access latency. Moreover, by considering the cooperation of all access points (...
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。

Recently, Cell-free Massive MIMO (mMIMO) has emerged as a promising technology to provide uniform coverage and high rates via joint coherent transmission. In this paper, we investigate multi-task OtA FL in Cell-free mMIMO systems. We propose optimal designs of transmit coefficients and receive ...
This work explores the potential of SSMs for ICL-based equalization in cell-free massive MIMO systems. Results show that selective SSMs achieve comparable performance to transformer-based models while requiring approximately eight times fewer parameters and five times fewer floating-point operations. ...
