1. A method performed by a User Equipment (UE) adapted to operate in a wireless communication system, the method comprising:
receiving, from a network, a first sidelink grant on a Physical Downlink Control Channel (PDCCH);
in a first duration related to the first sidelink grant:
(i) associating a Hybrid Automatic Repeat reQuest (HARQ) process Identifier (ID) corresponding to the first sidelink grant to a sidelink process;
(ii) storing a Media Access Control (MAC) Protocol Data Unit (PDU) in a HARQ buffer associated with the sidelink process;
(iii) storing the first sidelink grant;
(iv) generating a transmission according to the first sidelink grant; and
(v) performing the transmission of the MAC PDU on a resource indicated by the first sidelink grant;
in a second duration related to the first sidelink grant:
(i) flushing the HARQ buffer of the sidelink process;
(ii) receiving, from the network, a second sidelink grant on a PDCCH for retransmission; and
(iii) based on the HARQ process ID corresponding to the second sidelink grant received on the PDCCH being associated with the sidelink process for which the HARQ buffer is empty, ignoring the second sidelink grant.
