Abstract: A system and a method are disclosed for transmission of 5G side link positioning reference signals (SL-PRS) while in 5G side link mode 2 (for example, V2X). Using a shared resource pool and no data transmission, a UE determines three parameters (time, frequency, and PRS index) for transmission of a PRS using a comb structure. Using a dedicated resource pool with data transmission, the UE populates a time frequency grid for slot transmission so that PRS does not conflict with demodulation reference signals (DMRS).
