User-Centric Perspective in Random Access Cell-Free Aided by Spatial Separability
User-Centric Perspective in Random Access Cell-Free Aided by Spatial Separability
In a cell-free massive multiple-input multiple-output (CF-mMIMO) network, multiple access points (APs) actively cooperate to serve users' equipment (UEs). We consider how the random access (RA) problem can be addressed by such a network under the occurrence of pilot collisions. To find a solution, we embrace the user-centric perspective, which …
