      Add Sidelink (SL) carrier frequency · 555a54f8
      Robert Schmidt authored
      1. Adding a "SL" frequency for Sidelink mode. The
         importance of this variable is to ensure that
         when we are in mode 1 (UE+UE+gNB), that the slot
         configuration and frequencies do not overlap. This
         SL frequency is important for rotation and allows
         us to utilize the OFDM modulation and demodulation
         functions that already exist in OAI.
      2. Adding sl_mode to the command line for proper UE
         deployment when in SL mode. sl_mode can be set to 0,
         1, or 2. sl_mode 0 indicates no-Sidelink at all,
         mode 1 is gNB, UE, and UE (3GPP defines mode numbers).
         sl_mode 2 indicated UE to UE communications with no
         gNB at all.
      3. New functions for calculating the carrier frequency
         for SL mode.

      bugfix: change memory management of interface between PHY and MAC scheduler · 733c7e5e
      Cedric Roux authored
      This commit fixes a bug caused by global variables in the gNB_MAC_INST
      structure used to transfer MAC scheduler's results to the PHY layer.
      
      When using several threads in the PHY layer, it may happen that the
      MAC scheduler is called a second time by the second PHY thread for the
      next slot before the content of the global variables in the gNB_MAC_INST
      structure used to store the result of the MAC scheduler for the current
      slot have been consumed by the first thread, leading to unpredictable
      results (all of them certainly wrong).
      
      The solution is to introduce a small memory management module for the
      interface between the PHY threads and the MAC scheduler. The MAC
      scheduler now fills the data structures passed to it, and not a
      global variable anymore. The PHY layer manages the structures and
      ensures that no data is overwritten before being fully consumed by
      the various threads of the PHY layer.
      
      Some care has to be taken because several PHY threads will access the
      same structures at the same time for a given slot (in read mode, so
      it's okay). A mechanism of reference counting has thus been introduced.
      
      Only one CC is supported. This restriction should not be too hard
      to remove if/when needed. (The code before this commit does not seem
      to work for more than one CC anyway.)

      int32_t to c16_t conversion · 4dd579e0
      Melissa Elkadi authored
      This commit includes changes to the function
      footprints for vaiours NR UE and gNB functions.
      It does not updated the LTE code. For functions
      shared by both LTE and 5G, we maintained the original
      LTE footprint and argument structure.
      
      Several of the simulators that use these functions
      have been updated as well. The specific usage of these
      functions which index into the int32_t buffers and
      treat the first int16_t and the real and the second
      as the complex should be modified in the near future.

      RC: forward declarations and link physims better · 8a15fb7c
      Robert Schmidt authored
      The simulators have been changed: due to linker errors that would arise
      otherwise, a lot of functions are defined in them to avoid such errors.
      Some functions are also defined in header files; in this commit, we
      define most functoins in nr_dummy_functions.c, which is compiled in, not
      by including the C file, but by adding it to the target in
      CMakeLists.txt
      
      - nr_dlsim+nr_ulsim need NR_IF_Module_init(), so it cannot be in
        nr_dummy_functions, but the others need it
      - Link correcr NR_IF_Module_init() into these simulators, and reduce
        overall link list
      - Correctly link remaining simulators
