Changelog

14/06/20

• we are not clear on how the parameters are extracted from the config file
• in ssc struct
• for some values it is okay and for others it is zero (in config_request)
• This causes Assertion Failures leading to termination on PNF side.

15/06/20

• The values to config request are assigned in: config_common() in config.c
• need to add lines for cfg->nfapi_config
• the config request unpacked on pnf side still has some zero values, which causes assertional failure in from_nrarfcn()

16/06/20

• Config request is recived and unpacked correctly
• Regarding config response
  • we are confused about its' struct definition
  • it says list of TLVs in its entirety
  • and we need to dyanmically insert the invalid TLVs after checking in a categorical fashion
  • Need to think of a data structure to enable this feature.

  list of uint8_t tlvs
  list of uint16_t tlvs
  list of uint32_t tlvs
  }list of tlvs
  

• Need the N_RB value to be non-zero and obtained from the config file. (carrier config grid size) int N_RB = gNB_config->carrier_config.dl_grid_size[gNB_config->ssb_config.scs_common.value].value;
• how is this gNB_config assigned its values?

19/06/20

• ret = openair0_device_load(&ru->rfdevice,&ru->openair0_cfg); sloc: 1428 in nr-ru.c

• the ru->rfdevice has all members zero or null.

• This issue was solved by adding sdr_addrs to config file of PNF.

• if (cfg->tdd_table.max_tdd_periodicity_list[nr_tti].max_num_of_symbol_per_slot_list[symbol_count].slot_config.value==1

  • throws segmentation error
  • max_tdd_periodicity_list is not assigned memory
