Introduced control on TA transmission and TA update application. - ta_timer at gNB side to control the transmission of TA to the UE. This is now happening every 20 slots. - when the timer resets gNB is now transmitting the TA whether it is zero or not. - introduced struct NR_UL_TIME_ALIGNMENT_t to handle configuration of time alignment related parameters. - UE PHY RX: is now triggered through a flag when to store the TA command, the frame and slot when the application should occur. - UE PHY TX: when the tx frame and slot match the time alignment configuration, it process the TA command and applies the TA update --- executables/nr-ue.c | 26 ++++++++- openair1/PHY/defs_nr_UE.h | 21 ++++++- openair1/SCHED_NR_UE/defs.h | 4 +- openair1/SCHED_NR_UE/phy_procedures_nr_ue.c | 28 ++++++++-- openair2/LAYER2/NR_MAC_UE/mac_proto.h | 5 +- openair2/LAYER2/NR_MAC_UE/nr_ue_procedures.c | 26 +++++---- .../LAYER2/NR_MAC_gNB/gNB_scheduler_dlsch.c | 55 +++++++++++-------- openair2/LAYER2/NR_MAC_gNB/mac_proto.h | 1 + 8 files changed, 118 insertions(+), 48 deletions(-) diff --git a/executables/nr-ue.c b/executables/nr-ue.c index fcbd659bbe..a781c5fdcd 100644 --- a/executables/nr-ue.c +++ b/executables/nr-ue.c @@ -461,6 +461,15 @@ void UE_processing(void *arg) { UE_nr_rxtx_proc_t *proc = &rxtxD->proc; PHY_VARS_NR_UE *UE = rxtxD->UE; processSlotRX(UE, proc); + uint8_t gNB_id = 0; + + // params for UL time alignment procedure + NR_UL_TIME_ALIGNMENT_t *ul_time_alignment = &UE->ul_time_alignment[gNB_id]; + uint8_t numerology = UE->frame_parms.numerology_index; + uint16_t bwp_ul_NB_RB = UE->frame_parms.N_RB_UL; + int slot_tx = proc->nr_tti_tx; + int frame_tx = proc->frame_tx; + //printf(">>> mac ended\n"); // Prepare the future Tx data /* @@ -473,6 +482,21 @@ void UE_processing(void *arg) { #endif */ + /* UL time alignment + // If the current tx frame and slot match the TA configuration in ul_time_alignment + // then timing advance is processed and set to be applied in the next UL transmission */ + if (UE->mac_enabled == 1) { + + if (frame_tx == ul_time_alignment->ta_frame && slot_tx == ul_time_alignment->ta_slot){ + LOG_D(PHY,"Applying timing advance -- frame %d -- slot %d\n", frame_tx, slot_tx); + + //if (nfapi_mode!=3){ + nr_process_timing_advance(UE->Mod_id, UE->CC_id, ul_time_alignment->ta_command, numerology, bwp_ul_NB_RB); + ul_time_alignment->ta_frame = -1; + ul_time_alignment->ta_slot = -1; + //} + } + } if (proc->nr_tti_tx == NR_UPLINK_SLOT || UE->frame_parms.frame_type == FDD){ @@ -480,7 +504,7 @@ void UE_processing(void *arg) { if (UE->mode != loop_through_memory) - phy_procedures_nrUE_TX(UE,proc,0,thread_id); + phy_procedures_nrUE_TX(UE,proc,gNB_id,thread_id); } diff --git a/openair1/PHY/defs_nr_UE.h b/openair1/PHY/defs_nr_UE.h index 19f4365a29..663e005d65 100644 --- a/openair1/PHY/defs_nr_UE.h +++ b/openair1/PHY/defs_nr_UE.h @@ -871,6 +871,16 @@ typedef struct UE_NR_SCAN_INFO_s { int32_t freq_offset_Hz[3][10]; } UE_NR_SCAN_INFO_t; +typedef struct { + /// flag used by MAC to inform PHY about a TA to be applied + unsigned char apply_ta; + /// frame and slot when to apply the TA as stated in TS 38.213 setion 4.2 + int16_t ta_frame; + char ta_slot; + /// TA command and TAGID received from the gNB + uint8_t ta_command; + uint8_t tag_id; +} NR_UL_TIME_ALIGNMENT_t; #include "NR_IF_Module.h" @@ -1066,9 +1076,14 @@ typedef struct { int rx_offset; /// Timing offset int rx_offset_diff; /// Timing adjustment for ofdm symbol0 on HW USRP int time_sync_cell; - int timing_advance; ///timing advance signalled from eNB - int hw_timing_advance; - int N_TA_offset; ///timing offset used in TDD + + /// Timing Advance updates variables + /// Timing advance update computed from the TA command signalled from gNB + int timing_advance; + int hw_timing_advance; + int N_TA_offset; ///timing offset used in TDD + NR_UL_TIME_ALIGNMENT_t ul_time_alignment[NUMBER_OF_CONNECTED_gNB_MAX]; + /// Flag to tell if UE is secondary user (cognitive mode) unsigned char is_secondary_ue; /// Flag to tell if secondary eNB has channel estimates to create NULL-beams from. diff --git a/openair1/SCHED_NR_UE/defs.h b/openair1/SCHED_NR_UE/defs.h index 66398c393e..4b4800398e 100644 --- a/openair1/SCHED_NR_UE/defs.h +++ b/openair1/SCHED_NR_UE/defs.h @@ -292,10 +292,10 @@ int8_t nr_find_ue(uint16_t rnti, PHY_VARS_eNB *phy_vars_eNB); /*!
