- 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

- Forward UE capabilities in F1 handlers - Store at MAC - Update CellGroupConfig with UE Capabilities of the UE
-
Robert Schmidt authored
- 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 wommit.

!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 SystemInformationBlock 1 is handled at the DU and sent to the CU in the F1 Setup Request. Hence, move it down to 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()

As with the ServingCellConfigCommon, the ServingCellConfigDedicated is a radio-related structure to be handled at the DU.
-
Robert Schmidt authored
The ServingCellConfigCommon is an inherently radio-related configuration. As such, it should be handled by the DU, not the CU. Therefore, move it "down" to the MAC.
-
Robert Schmidt authored
The PCI is given to the CU from the DU in the F1 Setup Request message. It is a part of the DU, so move it "down".

The F1 Setup Response contains the cell(s) to activate. Hence, prevent the radio from starting by waiting for the F1 Setup Response before continuing.
