System Level (SYS)#

This package provides differentiable system-level simulation functionalities for multi-cell networks.

It is based on a physical layer abstraction that computes the block error rate (BLER) from the PostEqualizationSINR. It further includes Layer-2 functionalities, such as link adaptation (LA) for adaptive modulation and coding scheme (MCS) selection, downlink and uplink power control, and user scheduling.

Sionna SYS also provides network-topology generation utilities for outdoor UMi, UMa, and RMa hexagonal grids, TR 38.901 multi-cell calibration layouts, and indoor-office and indoor-factory deployments. These utilities generate BS and UT locations and related topology state, including wraparound virtual BS locations where applicable. Their outputs can be passed directly to set_topology().
