Method and apparatus for sidelink terminal to transmit and receive signal related to channel state report in wireless communication system

A first user equipment (UE), comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, cause the first UE to perform operations comprising:
• transmitting, to a second UE, sidelink control information (SCI) including information related to channel state information (CSI) request,
• wherein a CSI report is triggered by the SCI with the information related to the CSI request;
• transmitting, to the second UE, a CSI-reference signal (CSI-RS) within a physical sidelink shared channel (PSSCH) transmission, only when the CSI report is triggered by the SCI;
• and
• receiving, from the second UE, the CSI report related to the CSI-RS,
• wherein the CSI report is received based on a latency bound of the CSI report from the triggering of the CSI report in terms of number of slots.

A second user equipment (UE), comprising:

• wherein a CSI report is triggered by the SCI with the information related to the CSI request;
• receiving, from the first UE, a CSI-reference signal (CSI-RS) within a physical sidelink shared channel (PSSCH) transmission, only when the CSI report is triggered by the SCI;
• and
• transmitting, to the first UE, the CSI report related to the CSI-RS,
• wherein the CSI report is transmitted based on a latency bound of the CSI report from the triggering of the CSI report in terms of number of slots.
