Before, we only considered ta_Common_r17 and the SAT position from SIB19 to compute the initial timing advance value. This is good enough if the satellite does not move too fast (e.g. GEO satellite). Now we also consider ta_CommonDrift_r17 and the SAT velocity together with the epoch time from SIB19. This improves the accuracy of the initial TA computation, esp. for LEO satellite scenarios.
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.
