This merges the following MRs:
- MR !1436 fairRR LTE scheduler fixes: should make the connection more stable, less UL retransmissions
- MR !1386 phy sync improvements: the 5G NR UE should sync better
- MR !1361 FDD support (no traffic): adds FDD support for the scheduler, but heavy traffic has not been tested
- MR !1447 using uid for PUCCH RRC conf: use the RRC UID to decide on PUCCH resources, should in particular avoid the "PUCCH straddles DC carrier" assert
- fix for 5G F1 RFsim test fail
We compute the preferred DL TDAs when receiving the cellGroup from the
RRC. However, in F1 and the RFsim, it seems that the scheduler tries to
access the preferred DL TDAs before they have been set after receiving
the cellGroup. In this commit, add a simple check to verify the
preferred TDA has been set up.
Also, the allocation of the eNB measurement
report keeps getting commented out becasue
the compiler throws an error. I have un-commented
the allocation of memory (becasue it breaks NSA
mode) and added a memset to ensure we are using
the allocated memory. This gets rid of the
warning and ensures NSA mode still works.
T tracer was not functional anymore. because init_tpools() was called
before T_Config_Init().
The problem was that init_tpools() creates some threads and T_Config_Init()
does call fork() and the child process (which is the one running the
softmodem, the parent process is used to monitor it, this is the design
of the T tracer, maybe to change at some point, it's too complicated) has
no thread after the fork(). The threads created by init_tpools() are gone.
Game over.
In conclusion: T_Config_Init() has to be called very early in the life of
the softmodem, at least before init_tpools().
It seems that the RA procedure in the gNB was modified so
the RAR is sent in a single tx_data_req. The emualted mode
was not previously handling this. We now only process the
PDU in the rx_ind that has a matching preamble. If any
other PDUs exist, we ignore them and only build Msg3 based
on this single matching RAR PDU.
Also, two bug fixes applied here in the emulate-l1 mode.
