If at all, it is a container for multiple lists. The next commit introduces a NR_UE_list_t structure that organizes UEs in lists such that it is easier to go through the UEs. --- openair1/SIMULATION/NR_PHY/dlsim.c | 8 +- openair2/LAYER2/NR_MAC_gNB/config.c | 14 +-- openair2/LAYER2/NR_MAC_gNB/gNB_scheduler.c | 86 +++++++++---------- openair2/LAYER2/NR_MAC_gNB/gNB_scheduler_RA.c | 22 ++--- .../LAYER2/NR_MAC_gNB/gNB_scheduler_dlsch.c | 33 ++++--- .../LAYER2/NR_MAC_gNB/gNB_scheduler_phytest.c | 66 +++++++------- .../NR_MAC_gNB/gNB_scheduler_primitives.c | 75 ++++++++-------- .../LAYER2/NR_MAC_gNB/gNB_scheduler_ulsch.c | 16 ++-- openair2/LAYER2/NR_MAC_gNB/mac_proto.h | 2 +- openair2/LAYER2/NR_MAC_gNB/main.c | 36 ++++---- openair2/LAYER2/NR_MAC_gNB/nr_mac_gNB.h | 4 +- openair2/NR_PHY_INTERFACE/NR_IF_Module.c | 4 +- 12 files changed, 181 insertions(+), 185 deletions(-) diff --git a/openair1/SIMULATION/NR_PHY/dlsim.c b/openair1/SIMULATION/NR_PHY/dlsim.c index 38400cab51..a2da10797e 100644 --- a/openair1/SIMULATION/NR_PHY/dlsim.c +++ b/openair1/SIMULATION/NR_PHY/dlsim.c @@ -698,7 +698,7 @@ int main(int argc, char **argv) nr_ue_phy_config_request(&UE_mac->phy_config);
