Change subject: Track scheduled UL blocks through USF ...................................................................... Patch Set 1: (1 comment) https://gerrit.osmocom.org/c/osmo-pcu/+/23492/1/src/gprs_rlcmac_sched.cpp File src/gprs_rlcmac_sched.cpp: https://gerrit.osmocom.org/c/osmo-pcu/+/23492/1/src/gprs_rlcmac_sched.cpp@463 PS1, Line 463: poll_fn = rts_next_fn(fn, block_nr); I'm not totally understanding why this rts_next_fn is needed here TBH. According to this: 1- RTS.req FN=13 sends DL message with USF=0 2- DATA.ind FN=17 we receive an UL block from MS managing USF=0 So that means that whenever we request USF on FN = x, the PCU expects the response on FN = x + 1. However, I always though that requesting USF on FN = x meant the MS would send the UL block on FN = x too (because there's a UL/DL delay opf a few TS iirc). Someone willing to shed some light on this would be great.
