From 589ced9c7ab586ffbf12194fe7f26ec82d97d780 Mon Sep 17 00:00:00 2001 From: matzakos Date: Fri, 10 May 2019 18:27:25 +0200 Subject: [PATCH 01/58] 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 30/58] nr-ip-over-LTE: Modification to support both use cases:
 DLSCH phy-test scheduling (random data generation in every opportunity) AND
 DLSCH scheduling only when there is IP traffic arriving through the LTE stack
 (noS1 mode)

Subject: [PATCH 36/58] 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.
