This abstract describes techniques for channel estimation in a two-stage sidelink control system using demodulation reference signals (DMRS). In this system, a user equipment (UE) transmits DMRS for the sidelink data channel. The UE then transmits the second stage of the sidelink control using either antenna ports or a precoder used for the sidelink data channel. The receiving device receives the DMRS, estimates the channel, and demodulates the second stage of the sidelink control based on the estimated channel. The receiving device has the flexibility to determine which DMRS to use for the estimation and demodulation process.
