[srsran-users] Implementing V2X sidelink over srsRAN

[Andrea Lacava]

Dear srsRAN community,


I am currently working on a project involving the use of V2X and LTE sidelink.
I have found the introduction guide on the official documentation (https://docs.srsran.com/en/latest/app_notes/source/cv2x/source/index.html) and read the code in lib/examples/pssch_ue.c and I have some questions about it:

  *   In 3GPP TR 21.914 V14.0.0 Section 7, the V2X for LTE is introduced, presenting two different communication interfaces for it: LTE-PC5 and LTE-Uu. What interface is used in the example proposed?

  *   In the example proposed it seems that only the physical channel is being taken into account. Is there a way to use the pssch code with the enb code and the ue code?

  *   I have seen the pssch(.h / .c) implementation, but I can not find any API reference or guide in the code nor in the official documentation. Is there another way to understand how these functions work?


My final goal consists in creating an LTE eNB and a UE capable of sending and receiving data using the sidelink using both the communication interfaces reported above. Do you have any suggestions on where to start?


Thanks for your attention,

Best Regards
