Accurate cell-specific signal strength maps are essential for coverage analysis and interference assessment in dense urban networks. However, drive-test measurements are typically spatially sparse, leaving many street segments unobserved. This paper proposes a physics-informed hybrid model for street-level pathloss pre...

Accurate channel modelling is a key prerequisite for planning and improvement of wireless communication networks. Obtaining a precise channel model is therefore a pivotal task for telecommunication engineers. One method that has gained in popularity in recent years is ray-tracing. Given the widespread use, it is import...

Frequency-division duplex (FDD) to time-division duplex (TDD) spectrum refarming is often motivated by the expected gains of reciprocity-based multi-user multiple-input multiple-output (MU-MIMO) operation. However, many system-level evaluations rely on simplified user equipment (UE) placement models, which may overesti...
