A method performed by a sidelink transmitting user equipment (SL TX UE) for sidelink (SL) vehicle to everything (V2X) unicast transmission to a sidelink receiving user equipment (SL RX UE). The method includes: receiving, a Radio Resource Control (RRC) configuration from a base station, the RRC configuration includes at least information for enabling SL Channel State Information (CSI) reporting and first Modulation and Coding Scheme (MCS) information for SL transmission by the SL TX UE; transmitting, a CSI-Reference Signal (CSI-RS) measurement resource configuration to the SL RX UE for deriving an SL CSI report; transmitting, an aperiodic CSI report trigger to the SL RX UE for triggering the SL CSI report in a sidelink control information (SCI); and receiving, the SL CSI report from the SL RX UE in a Physical Sidelink Shared Channel (PSSCH).
