5G SA COST UE Error :Disconnecting rnti=0x4603.

[coolcoollly]

Issue Description

[Describe the issue in detail] I build the gnb and open5gs core with the tutorial (https://docs.srsran.com/en/latest/app_notes/source/5g_sa_COTS/source/index.html). I build the gnb and open5gs core successfully and NG connection successful. My handset(Honor X10) can register the network operator(00101), but the handset can not connect to internet and the gnb window print : RACH: slot=9131, cc=0, preamble=4, offset=0, temp_crnti=0x4601 RACH: slot=9291, cc=0, preamble=3, offset=0, temp_crnti=0x4602 RACH: slot=2731, cc=0, preamble=5, offset=0, temp_crnti=0x4603 Disconnecting rnti=0x4603. RACH: slot=2891, cc=0, preamble=3, offset=0, temp_crnti=0x4604 Disconnecting rnti=0x4604. RACH: slot=8331, cc=0, preamble=6, offset=84, temp_crnti=0x4605 Disconnecting rnti=0x4602.

Setup Details

[Specify details of the test setup. This would help us reproduce the problem reliably] srsRAN 22.04; open5gs; linux 18.04; uhd 3.15; usrp X310;

Expected Behavior

gnb and open5gs core are built successfully and NG connection successful. My handset can connect to internet with my 5G network operator.

Actual Behaviour

gnb and open5gs core are built successfully and NG connection successful. My handset(Honor X10) can register the network operator(00101), but the handset can not connect to internet and the gnb window print : RACH: slot=9131, cc=0, preamble=4, offset=0, temp_crnti=0x4601 RACH: slot=9291, cc=0, preamble=3, offset=0, temp_crnti=0x4602 RACH: slot=2731, cc=0, preamble=5, offset=0, temp_crnti=0x4603 Disconnecting rnti=0x4603. RACH: slot=2891, cc=0, preamble=3, offset=0, temp_crnti=0x4604 Disconnecting rnti=0x4604. RACH: slot=8331, cc=0, preamble=6, offset=84, temp_crnti=0x4605 Disconnecting rnti=0x4602.

Hey! Could you please rerun the experiment with eNB logs set to info level. and provide the logs? Also send the PCAP for the eNB. Thanks

Hey! Could you please rerun the experiment with eNB logs set to info level. and provide the logs? Also send the PCAP for the eNB. Thanks

Hey! I rerun the experiment and get the eNB logs set to info level and enb_mac_nr.pcap. And there is the same problem on enb window. enb.log enb_mac_nr.zip

[andrepuschmann]

Hey, the eNB logs show a few RF underruns and it should be good if they would go away. Not sure how powerful your computer is but make sure you have the CPU governor set to performance and maybe try to reduce the PUSCH MCS. Also, could you please give this branch a try. It includes a few RLC and PDCP fixes. Provide logs/PCAP again. Thanks

Hey, this is my computer CPU: Intel® Core™ i5-6500 CPU @ 3.20GHz × 4 . My CPU governor has been set to performance. And I used the same equipments to run 4G COST UE successfully. I tried to set both nr_pdsch_mcs and nr_pusch_mcs to 27,10,2,1, but the result is same(my phone Honor X10 can register the network operator(00101), but the handset can not connect to internet and the gnb window print disconnected). Then I modify my files in srsran/lib , srsran/srsgnb and srsran/srsue by the branch given above. And I run srsran/build/srsenb/src/srsenb again setting both nr_pdsch_mcs and nr_pusch_mcs to 10, but the problem is same. I give my enb.log and enb_mac_nr.pdcp in this run. enb_mac_nr.zip enb.log This is the branch I found: Finally I am very suspicious that my phone(Honor X10 ) have the problem to connect to the gnb, so I want to buy a phone used in the the tutorial (https://docs.srsran.com/en/latest/app_notes/source/5g_sa_COTS/source/index.html). Do you have more information about Oneplus Nord 5G? Is Oneplus Nord 5G like the picture?

This is the same issue as #886. I know this was flagged earlier, but #886 is more descriptive. Closing it and tracking state there.
