Visibility Region Spatial Distribution Dataset for XL-MIMO Arrays
The Visibility Region(VR)information can be used to reduce the complexity in transmission design of EXtremely Large-scale massive Multiple-Input Multiple-Output(XL-MIMO)systems.Existing theoretical analysis and transmission design are mostly based on simplified VR models.In order to evaluate and analyze the performance of XL-MIMO in realistic propagation scenarios,this paper discloses a VR spatial distribution dataset for XL-MIMO systems,which is constructed by steps including environmental parameter setting,ray tracing simulation,field strength data preprocessing and VR determination.For typical urban scenarios,the dataset establishes the connections between user locations,field strength data,and VR data,with a total number of hundreds of millions of data entries.Furthermore,the VR distribution is visualized and analyzed,and a VR-based XL-MIMO user access protocol is taken as an example usecase,with its performance being evaluated with the proposed VR dataset.
