Abstract
The blockage of propagation paths between the base station and user equipment, as well as micromobility due to fast rotation of the UE in the user's hands, are known to be the main phenomena affecting the performance of 6 G (sub-)terahertz cellular systems. Practical measurements of the received signal power (RSP) are generally limited to these phenomena in isolation. In this dataset, we provide time-series of the RSP, simultaneously capturing blockage, micromobility, and beamtracking.
The traces produced can be utilized for various tasks, including the development of statistical tests for discriminating blockage and micromobility events, design of beamtracking algorithms, etc.
The measurement campaign was carried out in an empty hall with length 7.5 m, width 4.5 m, and height 3 m. The BS-to-UE distances were set to 3, 5, and 7 m. The authors considered a blocker crossing the LoS at a standard walking speed of 3.5 km/h right in the middle of the BS-to-UE distance. BS and UE heights were considered: 1,35 m corresponding to the LoS blockage by a chest, and 1,65 cm, corresponding to the head blockage.
On the first level of hierarchy, the dataset is divided into two subgroups based on physical parameters of the set-up (i.e. UE height and the BS-to-UE distance). A subgroup is identified by folder name in the following format: "H###cm_L###cm", where '###' is the numeric value of height and distance in cm respectively. On the second level, the folder names contain the following: "<application>_<beamtracking type>", where beamtracking type can be either "On Demand" or "Regular", while application is one the following: racing game, phone calling, VR, and video watching. Each folder contains 60 traces per beamtracking period (20, 80, 160, 320, 1000, 2000 ms) in TXT format (naming convention: "<application>_<beamtracking period in ms>_<date>-<time>.txt").
Each generated trace is of 60 s length. A trace file consists of 4 columns: time, received signal power in dBm regardless of micromobility, attenuation due micromobility in dBm, received signal power in dBm with respect to micromobility. When a beamtracking procedure occurs, the received signal power is assumed to be -100 dBm.
