From 63989e8a694485b3e1ccb0d0763d754a57c13103 Mon Sep 17 00:00:00 2001 From: Robert Schmidt Date: Thu, 17 Feb 2022 19:53:33 +0100 Subject: [PATCH] Fix for F1 RFsim fail We compute the preferred DL TDAs when receiving the cellGroup from the RRC. However, in F1 and the RFsim, it seems that the scheduler tries to access the preferred DL TDAs before they have been set after receiving the cellGroup. In this commit, add a simple check to verify the preferred TDA has been set up. --- openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_dlsch.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_dlsch.c b/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_dlsch.c index 0d857a0ba9..cd34a543c7 100644 --- a/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_dlsch.c +++ b/openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_dlsch.c @@ -895,7 +895,10 @@ void nr_fr1_dlsch_preprocessor(module_id_t module_id, frame_t frame, sub_frame_t /* This is temporary and it assumes all UEs have the same BWP and TDA*/ int UE_id = UE_info->list.head; NR_UE_sched_ctrl_t *sched_ctrl = &UE_info->UE_sched_ctrl[UE_id]; - const int tda = RC.nrmac[module_id]->preferred_dl_tda[sched_ctrl->active_bwp ? sched_ctrl->active_bwp->bwp_Id : 0][slot]; + const int bwp_id = sched_ctrl->active_bwp ? sched_ctrl->active_bwp->bwp_Id : 0; + if (!RC.nrmac[module_id]->preferred_dl_tda[bwp_id]) + return; + const int tda = RC.nrmac[module_id]->preferred_dl_tda[bwp_id][slot]; int startSymbolIndex, nrOfSymbols; const struct NR_PDSCH_TimeDomainResourceAllocationList *tdaList = sched_ctrl->active_bwp ? sched_ctrl->active_bwp->bwp_Common->pdsch_ConfigCommon->choice.setup->pdsch_TimeDomainAllocationList :
