Patent ID: 11924927

Abstract:
A method and apparatus for performing sidelink communications in a wireless transmit receive unit (WTRU) using Long Term Evolution (LTE) and New Radio (NR) technologies is described herein. A WTRU receives downlink control information (DCI) on a physical downlink control channel (PDCCH) from a gNodeB (gNB), wherein the DCI is associated with a cyclic redundancy check (CRC). The a determination is made as to whether the DCI is for an LTE or NR technology sidelink transmission. On a condition that the DCI is for NR technology, the WTRU determines which transmit modulation and coding scheme (MCS) table to apply based on the masking of at least some of the bits in the CRC. Then the WTRU transmits sidelink data on resources indicated by the DCI using the determined MCS table. The WTRU may also receive HARQ feedback on resources indicated by the DCI for HARQ feedback.
