1. A method for use in a wireless transmit receive unit (WTRU) for sidelink communication, the method comprising:
receiving a resource pool identity (ID);
based on a determination to include information related to demodulation reference signal (DM-RS) density for a physical sidelink shared channel (PSSCH) transmission in sidelink control information (SCI), transmitting the SCI including the information related to DM-RS density, wherein the determination is based on the resource pool ID, and wherein the SCI is associated with the PSSCH transmission; and
transmitting the PSSCH transmission with one or more DM-RSs at a first DM-RS density based on the information related to DM-RS density.
