1. A method performed by a first wireless device in a wireless communication system, the method comprising,
establishing a PC5-Radio Resource Control (RRC) connection with a second wireless device; and
receiving a Sidelink control information (SCI),
wherein a sidelink (SL) Channel State Information (CSI) reporting is triggered by the SCI with a CSI request;
for a first pair of a Source ID and a Destination ID corresponding to the PC5-RRC connection,
based on that SL CSI reporting has been triggered, and
based on that (i) a Media Access Control (MAC) entity of the first wireless device has SL resources allocated for new transmission and (ii) the SL resources can accommodate an SL SCI reporting Medium Access Control (MAC) Control Element (CE) and a subheader of the SL SCI reporting MAC CE:
(1) instructing to generate the SL SCI reporting MAC CE;
(2) cancelling the triggered SL CSI reporting; and
(3) triggering the new transmission for a MAC protocol data unit (PDU),
wherein the generated SL SCI reporting MAC CE is multiplexed in the MAC PDU.
