- until now, on every iteration, the scheduler checked for changed parameter
(and verified some)
- this functionality moves to the FlexRAN Agent, which verifies all parameters
* individually, e.g. Max MCS <= 28 for DL
* group-based, e.g. the sum of slice percentages is <= 100
- slice configuration changes are only applied if all verifications pass
- it is assumed in the scheduler, that configuration passed from outside is
correct and can be used "as-is"
fix accounting setting
- uncomment "Couldn't find RNTI for UE X" in UE_RNTI() and rb_alloc in
pre_processor_reset() as they only inflate the debug output with little
benefited
- "doing ue_schedule_spec" is now displayed for individual UEs (and individual
CCs)
- show messages when not scheduling UE in ue_schedule_spec() due to invalid
slice or if not in RRC_CONNECTED
- slice multiplexing resorts UE_list for its purposes with restoring the
original order
- in order to keep the order in UE_list, resort to original order after
multiplexing
- ideally, this would happen in the multiplexing but currently, the slice_idx
is not passed to multiplexing (it does not care), so this cannot be done ATM
Incoming slice configuration changes are buffered in an intermediate structure.
The MAC scheduler periodically polls the agent about changes. If there has been
a slice configuration change, apply it.
- introduce structure in RC for slicing conf (UL/DL)
- move global variables regarding slice configuration into RC
- change ue_slice_membership(): consider UL/DL
- remove the unnecessary header files
- set default parameters: one slice
1. Fix UE_CONTEXT_SETUP_REQUEST and CONTEXT_MODIFICATION_REQUEST encode/decode
2. Add gNB_DU_CONFIGURATION_UPDATE and gNB_CU_CONFIGURATION_UPDATE procedure
3. Add C_RNTI_TO_BIT_STRING function
4. Add INITIAL_UL_RRC_MESSAGE_TRANSFER procedure and with mac_du_data_ind (MSG3)
5. Add GNB-CUSystemInformation extension part for the F1SetupResponse procedure
lte-softmodem, lte-uesoftmodem, nr-softmodem, nr-uesoftmodem, polartest, ldpctest, ulsim, dlsim all compile
functionality and performance to be tested by CI
