MULTIPLEXING MECHANISMS FOR SL PRS AND PSCCH TRANSMISSION

Abstract: an apparatus and system of providing a sidelink position reference signal (sl prs) and physical sidelink control channel (pscch) transmission are described. the pscch, which carries sidelink control information (sci), and sl prs are time division multiplexed (tdmed) in a particular slot. the pscch is transmitted in a dedicated resource pool for sl prs that includes a dedicated resource region allocated for the pscch transmission. the sl prs is transmitted in a shared resource pool for sl communication and the sl prs. a sl prs resource index is indicated in a second stage sci carried by a physical sidelink shared channel (pssch), which is tdmed with the pscch and the sl prs. a starting symbol and/or length of the sl prs is predefined in the 3 gpp specification or (pre-)configured by higher layer signaling.
