Current FAPI slot_ahead value for WLS is too low for UL, as we see these
errors:
[NR_MAC] Unexpected ULSCH HARQ PID 14 (have 3) for RNTI 0xa68e
[NR_MAC] UE a68e expected HARQ pid 3 feedback at 586. 7, but is at 587.17 instead (HARQ feedback is in the past)
Similarly to nFAPI, scale it by mu (for mu=1 => slot_ahead=2) to give
additional time, which removes these warnings at the VNF.
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.
