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 adaption (LA) for adaptive modulation and coding scheme
(MCS) selection, downlink and uplink power control,
and user scheduling.
Base stations can be placed on a spiral hexagonal grid,
where wraparound is used for pathloss computation.

A good starting point for Sionna SYS is the available tutorials page.
