From 589ced9c7ab586ffbf12194fe7f26ec82d97d780 Mon Sep 17 00:00:00 2001 From: matzakos Date: Fri, 10 May 2019 18:27:25 +0200 Subject: [PATCH 001/156] Downlink IP traffic flow using LTE RAN stack over NR-PHY. Downlink traffic reaching PHY of gNB now using the noS1 mode. Extensions required for the reception through the LTE RAN stack at the UE side. --- openair1/PHY/CODING/3gpplte_sse.c | 32 +- openair1/PHY/NR_TRANSPORT/nr_dci_tools.c | 48 +-- openair1/SCHED_NR/fapi_nr_l1.c | 55 ++- openair1/SCHED_NR/fapi_nr_l1.h | 3 + openair2/LAYER2/NR_MAC_gNB/gNB_scheduler.c | 68 ++-- .../LAYER2/NR_MAC_gNB/gNB_scheduler_phytest.c | 363 ++++++++++++++---- openair2/LAYER2/NR_MAC_gNB/main.c | 21 +- openair2/LAYER2/PDCP_v10.1.0/pdcp.c | 193 +++++++--- openair2/LAYER2/PDCP_v10.1.0/pdcp_fifo.c | 58 ++- openair2/NETWORK_DRIVER/MESH/classifier.c | 3 +- openair2/NETWORK_DRIVER/MESH/common.c | 5 + openair2/NETWORK_DRIVER/MESH/local.h | 4 + openair2/NETWORK_DRIVER/MESH/netlink.c | 2 +- 13 files changed, 625 insertions(+), 230 deletions(-) diff --git a/openair1/PHY/CODING/3gpplte_sse.c b/openair1/PHY/CODING/3gpplte_sse.c index 96dbcc3717..fdcc0e4132 100644 --- a/openair1/PHY/CODING/3gpplte_sse.c +++ b/openair1/PHY/CODING/3gpplte_sse.c @@ -213,7 +213,7 @@ char interleave_compact_byte(short * base_interleaver,unsigned char * input, uns 0b00000010, 0b00000001};

Subject: [PATCH 051/156] nr-ip-over-LTE: Resolved issue with duplicate IP
 packet at the receiver UE IP interface and packet losses are reduced.
 Remaining to identify why occasionally IP packets are received at the PDCP
 stack later than the time slot of their arrival at PHY/MAC. Introduced some
 debug logs, to be removed later.

From 3a8bf560da6de1977410a111cd8cd26782ae5118 Mon Sep 17 00:00:00 2001
From: Ahmed Hussein 
Date: Mon, 27 May 2019 18:31:20 +0200
Subject: [PATCH 078/156] channel estimation, compensation, etc ..

Added the following folder:
- ../openair1/PHY/NR_ESTIMATION/

Added the following file to CMakelists.txt:
- ../openair1/PHY/NR_ESTIMATION/nr_ul_channel_estimation.c

Added the following functions:
- nr_pusch_dmrs_rx
- nr_gold_pusch
- nr_ulsch_channel_level
- nr_ulsch_channel_compensation
- nr_ulsch_scale_channel is commented out (I think only used for downlink)

Changes from Khalid Ahmed Mahmoud Mohamed:
- nr_pusch_channel_estimation is used
- nr_ulsch_scale_channel is used
- nr_ulsch_channel_level is used
- nr_ulsch_channel_compensation is used
- multiple logging options for channel and signal magnitude

Subject: [PATCH 093/156] TBS fix at UE side + minor restructuring in
 "phy_procedures_nrUE_TX"

- TBS calculation was performed 2 times. Once in "phy_procedures_nrUE_TX" and
  another in "nr_ue_ulsch_procedures". The TBS calculation was wrong in "phy_procedures_nrUE_TX"
  and correct in "nr_ue_ulsch_procedures".

- The data generation was performed in "phy_procedures_nrUE_TX" with a wrongly
  calculated TBS because "ulsch_ue->nb_re_dmrs" wasn't set to a value, so the calculated
  TBS would be more than it should be. This doesn't create a problem in the test because
  the comparison between the TX and RX data is made using the correctly calculated TBS
  which is smaller.

- Solution was to perform data generation in "nr_ue_ulsch_procedures", and remove TBS calculation
  in "phy_procedures_nrUE_TX"

Subject: [PATCH 095/156] Set start_rb to 0

- start_rb was set to 30, and nb_rb was set to 50 with NB_RB_DL = 106.
- When the DC subcarrier is included in the RB allocation,
  this causes errors in FFT/IFFT operations arounf the DC subcarrier
- This leads to errors in unscrambling and decoding
