Robert Schmidt c609dd8fcf Implement common nr_get_mu() in nr_mac_common 
These functions look up the numerology, and code can be harmonized:

- ssb_index_from_prach()
- find_SSB_and_RO_available()
- schedule_nr_prach()

The next commits also need to look up the numerology from the
UplinkConfigCommon. This provides the common implementation to be used
in follow-up commits.

Laurent THOMAS 8f46b07b22 Lacking RRC check: avoid SEGV if the received packet is not what we believe 2024-10-07 13:39:29 +02:00
Laurent THOMAS f77f428767 Small optimization L2 to wireshark 
the code creates a sink to read all traced packets and drop it.  but
this works only if we send to a local address and if there is not
another sink (like if we trace both UE and gNB in the same machine).
this sink's purpose is only to prevent to get automatic packets back
from the kernel saying "no listener". So, instead of killing the trace
when we can't create the sink (as done previously), we now just let the
trace in operation.

andrewse 2335f5b6cf Don't call mac_rlc_data_ind when SRB0 already exist for UE. 
It can happen that L1 gives us a TB that we interpret as receiving UL
MAC TB with LCID "UL_SCH_LCID_CCCH1". This might or might not be
correct, but currently, we observe segfaults when trying to encode the
cellgroup in send_initial_ul_rrc_message() (encode_cellGroupConfig()).

This fix prevents a segfault by not delivering a MAC SDU to RLC if CCCH
is already present. Note that in some cases, this could still happen,
e.g. Resume Request. However, we don't support this message, so ignore
it for the moment.

This fix enables a gNB to operate continuously for extended periods
(days), which is essential for real deployment scenarios.

Closes: #756

Xin Zhe Khooi 163d058d4a introduce dedicated nr pdcp tick thread for F1 split 
Currently, NR PDCP ticks are active only with monolithic gNB, triggered by the MAC scheduler in gNB_scheduler.c.
In F1 split mode, as there is no MAC, there’s no source to advance the NR PDCP timer via "nr_pdcp_wakeup_timer_thread()".
This commit introduces a dedicated thread for NR PDCP ticks in gNB-CU and CU-UP mode.
Without it, packet losses at the F1 uplink would cause indefinite buffering, as t-Reordering won't expire due to the lack of NR PDCP timer ticks.

Raymond Knopp d2ebc356a0 removed division by num_antenna_ports in PDSCH precoding matrix generation.
