Set n_dmrs_cdm_groups = 1 for now.
Should be fixed accordingly to TS 38.214 section 5.1.6.2
using tables 7.3.1.2.2-1, 7.3.1.2.2-2, 7.3.1.2.2-3, 7.3.1.2.2-4 of TS 38.212
c_SRS was 61, which does not fit for 106 PRBs as it seems. Value 0 works.
Maybe not the right thing to do though (see 38.211 6.4.1.4.3,
table 6.4.1.4.3-1).
Also it seems necessary to pass desired LTE/NR bands when requesting
LTE UE capabilities. Today this is hardcoded, to be done better at
some point. We should get the bands from the eNB configuration and
the eNB/gNB X2 exchanges.
- DM-RS type {1,2} was wrongly assigned to {1,2} instead of {0,1}
- Num DM-RS CDM groups without data is now taken into account in mthread
decoding function
- number of DM-RS CDM groups without data for format 1_0 according to 5.1.6.2
3GPP TS 38.214 version 15.9.0 Release 15:
-- the UE shall assume the number of DM-RS CDM groups without data is:
-- 1 (CDM group 0) for the case of PDSCH with allocation duration of 2 symb
-- 2 (CDM group {0,1}) for all other cases.
- moved RRC structs checks and mac configuration to config_ue.c
- new implementation of DCI configuration according to 3GPP TS 38.331
version 15.9.0 Release 15 and 3GPP TS 38.213 version 15.9.0 Release 15
Selects the UE with the highest CQI. If two UEs have the same CQI,
choses the one with highest number of bytes in RLC queue. Allocates as
many RBGs as possible, and potentially continues with the next UE.
Selects UE with highest coefficient. Allocates until there are no more
RBGs to allocate, or UE has no more data. In the latter case, continues
with the next UE (second-highest coefficient).
- Loop only to next UE instead of jumping multiple
- mark used RBGs in rbg_mask
- Only calculate number of RBs based on CQI when UE is selected, instead
of calculating for all UEs which might be unnecessary.
- When looping the list of UEs for RB allocation, remove UEs that have
no data anymore instead of skipping them.
The preprocessor pre-allocates a CCE. Thus, when arriving at the check
for the number of RBs for retransmission, it is too late to skip the UE.
Therefore, only print a warning.
The default schedulers allocate a correct amount of RBs for
retransmissions, therefore it is ok.
