- store the assoc ID of a UE at the RRC
- if F1 receives an SCTP shutdown, it removes the endpoint
- F1 will also send an "F1 Lost Connection" message to the RRC
- it is not yet possible to reconnect a DU after it had already been
connected at the CU, since the CU F1AP task will try to rebind GTP,
which fails
- MAC creates CellGroupConfig and sends to RRC
- the RRC does not manually update the CellGroupConfig
- MAC handles the RRC processing timer
In this commit, any updates to the CellGroupConfig previously done at
the RRC don't work. In other words, MIMO etc don't work; this is
implemented in the next commit.
Note that the change to take out spCellConfig during reestablishment is
because after reestablishment, as per spec (38.331 5.3.7.2), the UE
should drop the spCellConfig, which we generate by default on the first
UE connection.
Furthermore, add a new variable apply_cellgroup to signal if, after RRC
processing timer, we wish to apply the CellGroup. In some situations,
e.g., Msg.4 ack, we do not want to apply the CellGroup, because for
instance in reestablishment, we await for a reconfiguration of cellgroup
that would be triggered too early.
!SIB1 is not correctly filled! This commit does not work with COTS UEs!
The next commit fixes this.
- Move radio config (e.g., minRXTXTIME, SIB1 TDA, do_SRS, etc) down to
MAC.
- Some parameters in MAC are redundant: delete them.
- Remove call to nr_mac_config_scc() from RRC and simulators, the MAC
initialization routine calls it implicitly
Previously, filling of F1 Setup Request depended on reading the RRC;
hence, for timing reasons, we only initialized and sent the F1 Setup
Request once the MAC and RRC are ready.
After moving SCC, SCD, MIB, and SIB1 to MAC, the MAC does not depend on
an RRC being present anymore, and hence, the F1 Setup Request does
neither. In this commit, we read the F1 Setup Request after initializing
the MAC.
The MasterInformationBlock is handled at the DU and sent to the CU in
the F1 Setup Response. Hence, move it down to the MAC. Furthermore:
- Change type because MIB_PDU_t is 4G type
- Simplify schedule_nr_mib()
