Repair nFAPI in 5G Add 5G nFAPI in OAI/Make it it work. Many commits in this branch are basically bug fixes of things that don't work properly, such as - check for correct conditions (e.g. instance numbers in the RAN context) - remove artificial limitation (e.g. only one PUCCH per TDD period in the PNF) - improve performance (reduce big mallocs, make some static buffers such as a global ring buffer for nFAPI messages in the PNF) - fix bugs in nFAPI (e.g., increase maximum message size to ~64kB instead of 1500 bytes, because the latter is way too small for many TX_data.requests in 5G, and it will delay message arrival unduly) - fix bugs in message enc/dec (e.g., handle FDD in config.request) - adjust the L1 such that the condition "we run monolithic" is not necessery (e.g., some message numbers in nFAPI struct where reset in MAC, instead of L1, and this breaks when running the PNF) There are instructions that explain how to set it up. Two CI tests have been added, one with COTS UE and MIMO in DL+UL in TDD numerology 1 (30kHz), and a second test with FDD mu=0 (15kHZ) in RFsimulator. These were some old to-dos that have been addressed. - test with COTS UE - 4x4 pipeline works good in DL, UL now also work - test in RFsim - make PNF status message - make FDD in u0 work
This directory contains the NFAPI code.
It comes in two parts:
1 - open-nFAPI
This is a clone of the github repository
(https://github.com/cisco/open-nFAPI,
commit b3bc579b1697eab829d5d8a2de59c93a61b88fa4).
The patch open-nfapi.oai.patch has then been applied.
2 - oai_integration
This is code written by David Price from Cisco to integrate
open-nFAPI into OpenAirInterface.
