LTE provides sidelink communication via the PC5 interface.
According to the "secondary literature" [1],[2],[3], the PC5 subframe is structured as follows:
- Symbol 0,1,3,4,6,7,9,10,12: PSCCH, PSSCH (Primary Sidelink Control / Shared Channel
- Symbol 2, 5, 8, 11: DMRS (Demodulation Reference Signal)
- Symbol 13: Guard for TX/RX Turnaround
Unfortunately, I cannot find the primary source for this subframe structure in the ETSI Technical Standards (e.g. ETSI TS 136 211 [4]). Could somebody please point me into the right direction?
Many thanks in advance,
EMC
