- PRACH Configuration Index = 98 is not suSpported by the Amarisoft UE simulator, as a number of PRACH occasions within the PRACH slot is > 1
- for PRACH Configuration Index = 100, number of time-domain PRACH occasions within a PRACH slot is 1
Multiple DUs host cells, whose cell ID cannot match (to identify them
uniquely). Hence, don't check for equality with CU, because otherwise,
we can never connect multiple DUs.
This is a workaround for a problem described in #706. In short, we
cannot reuse the cu_add/remove_f1_ue_data() functions if we are in an
integrated CU-UP/CP ("CU"), but then we can also not reliably use
different UE IDs in CU-UP and CU-CP (except if using even more hacks).
An assoc_id of 0 is used to mark UEs whose DU is "offline" (not
connected). In this patch, if a DU disconnects, we go through all UEs
and set their assoc_id to 0 if they belong to a UE that just went
offline.
This code printed BW masks (what is this) and number of MIMO layers. It
was dependent on the current DU, and only showed the information for the
current DU config (SCS, band). On DU disconnect, it leads to segfaults
to this dependency, and IMO is not useful in itself (it could rather be
printed when receiving the UE capabilities, for all bands etc.).
