Multiple UEs traffic with AmariSoft

[IbrahimBabiker87]

Its observed that with multiple UE scenario , not all UEs are taking traffic " Im using iperf3 udp", is there any way to enforce scheduler to schedule more UEs, for instance for 4 UEs scenario only one UE is initaiting the traffic while other UEs will be Idle " not connected":

the config file as per below:

gnb_id: 1                             # Optional UINT (411). Sets the numerical ID associated with the gNB.

gnb_id_bit_length: 32                     # Optional UNIT. Sets the bit length of the gnb_id above. Format: integer between [22 - 32]

ran_node_name: dell2srsgnb01                 # Optional TEXT (srsgnb01). Sets the text ID associated with the gNB. Format: string without spaces.

slicing:                                # Optional TEXT. Configure network slicing options. This can only be set via the configuration file.

Hi @IbrahimBabiker87 , thanks for posting. Can you enable all_level: info and attach logs and MAC and NGAP pcaps?

Thanks

[ismagom]

Actually the AmariUE log will be useful if you have that too.

[IbrahimBabiker87]

Hello,

Thank you for the reply please find attached logs,

Can you try with this configuration?

cell_cfg:
  pucch:
   sr_period_ms: 10
   f1_nof_cell_res_sr: 30
  csi:
    csi_rs_period: 40
  pdsch:
   max_alloc_attempts: 6
   max_pdschs_per_slot: 6
  pusch:
   max_puschs_per_slot: 6

Thanks

HI @ismagom thank you for you support,

with above configuration I can schedule 2 UEs out of 4,

@IbrahimBabiker87 Ignore this #292 (reply in thread) please. It was me jumping the gun

[herlesupreeth]

Hey, gnb.zip file is corrupted I guess cant extract it. Can you please reupload it?

Hi @IbrahimBabiker87 , we checked the code and in the end the warning log message you saw was a wrong message (we'll fix that).

It seems there is nothing to do with duplicates RNTIs, but it's a problem of GNB running out of PUCCH resources to allocate new UEs.
We found this in the logs

2023-11-10T09:03:06.993282 [DU-MNG  ] [I] ue=16 rnti=0x4629 proc="UE Create": Procedure started....
2023-11-10T09:03:06.993286 [DU-MNG  ] [W] Unable to allocate dedicated PUCCH resources for ue=16, cell=0
2023-11-10T09:03:06.993286 [DU-MNG  ] [W] RAN Resource Allocation failed for ue=16

Could you try adding this to your configuration?

cell_cfg:
  pucch:
   sr_period_ms: 10
   f1_nof_ue_res_harq: 8
   f1_nof_cell_res_sr: 30
   nof_cell_harq_pucch_res_sets: 2
   f2_nof_ue_res_harq: 8
   f2_nof_cells_res_csi: 8          # set to 16 if it still doesn't work
  csi:
    csi_rs_period: 40
  pdsch:
   max_alloc_attempts: 6
   max_pdschs_per_slot: 6
  pusch:
   max_puschs_per_slot: 6

If you can't get more than 16 UEs attaching, then push up f2_nof_cells_res_csi to 16.
Let us know if it works.

Thank You its working fine Now:
