Plan

Task-A [packing]

• Modify nfapi_p7_message_pack() in nfapi_p7.c
• In the switch case, change the labels as well as the pack functions:
  • pack_dl_config_request becomes pack_dl_tti_request
  • pack_ul_config_request becomes pack_ul_tti_request
  • pack_hi_dci0_request becomes pack_ul_dci_request
  • pack_tx_request becomes pack_tx_data_request

Task-B [unpacking]

• Modify nfapi_p7_message_unpack() in nfapi_p7.c
• Similarly change all the unpack functions within the switch-case block.
• Modify the behaviour of check_unpack_length() for the new TAGS

Task-C

• Write the dl_tti alternative for nfapi_vnf_p7_dl_config_req() in vnf_p7_interface.c and other such functions.
• Also check the function vnf_p7_pack_and_send_p7_msg() in vnf_p7.c for upgrade.
• Write the dl_tti equivalent for oai_nfapi_dl_config_req in nfapi_vnf.c and other such functions.
• Check if nr_schedule_response() needs to be upgraded

Testing

• Test by running VNF on a terminal and PNF in rfsim parallely

• If all works fine, move to UE testing.

• Check if the FAPI core functionality is not broken by running gNB in monolithic mode

• Syncwith the latest stable commit in develop branch

• Testing with a UE

  • Run VNF
  • Run PNF in rfsim
  • Run UE in rfsim

• This can be done on parallel terminals on the same machine or different machine with the appropriate configuration
