- CMakeLists modification: add QtWidgets library, add new source files, MOC (Meta-Object Compiler) on the given source file
- build_oai modification
- Activate new GUI with Qt on the UE side
- 2 x 3 widget with I/Q sample for PDSCH
- Drop-down list implementation
- previously, used magic numbers to designate nFAPI mode
- now, use string values (MONOLITHIC, PNF, VNF, ...)
- Remove printing of the nfapi mode to the console, as it's value is clear from the command-line argument
- Update usages of the --nfapi command-line parameter in scripts and documentation to reflect the change to string values
UHD documentation: "A tune request instructs the implementation how to
tune the RF chain."
This commit makes this configurable, from nr-softmodem, nr-uesoftmodem,
lte-softmodem, and lte-uesoftmodem.
In case of TDD we usually disable TX during RX.
Unfortunately some USRPs create self-interference after disabling TX.
To be able to work-around this issue, we add the flag "--continuous-tx".
The following was changed in this commit:
- A new struct in the mac instance was created
for all emulated L1 fields.
- NR UE RRC state bug was fixed
- Checking the RAR rnti based on the MAC instance
ra.ra_rnti and not hardcoding to 0x10b
- Modified the name of the new emulate_l2 flag
to make sense: emulate_l1
At this point we are successfully able to build.
Additionally, we can run the scenario,
however, it does not pass. It seems that the gNB
is not connecting to the proxy correctly. Just
wanted to push the progress so far. FYI, the items
that had to be changed to correct the linking issues
were the following:
- mac_rrc_data_ind_ue vs. nr_mac_rrc_data_ind_ue
- rrc_data_req vs. nr_rrc_data_req
- mac_rrc_data_req_ue vs. nr_mac_rrc_data_req_ue
- rrc_data_req_ue vs. rrc_data_req_nr_ue
- rrc_data_req vs. nr_rrc_data_req
The listed functions should be declard in the LTE/NR
UE directory depending on the functionality. Several
were mixed. i.e.: LTE functions being called in NR UE.
Also, removing siWindowLength, siWindowLength_int,
SIBType, SIBPeriod, and siPeriod_int from the NR UE RRC.
These variable were not used in the NR UE and are defined
for LTE only.
Lastly, in the NR_IF_Module.c of the NR UE, the global
variable def_dci_pdu_rel15 is not accessible. Need to
revisit this. For not it is commented out.
1. If VNF is slower than PNF, next scheduling will be done after resync.
2. If VNF is unstable in slot progress, next scheduling will be done in next stable status.
3. SFN/SLOT indications are queued in nrUE.
4. get_queue is used instead of unquque for FIFO operation.
