11. A WTRU, the WTRU comprising:
a processor and a transceiver which are configured to:
receive information indicating a configuration of one or more sidelink (SL) resource pools;
determine a set of resource pools for SL control information (SCI) decoding among the one or more SL resource pools;
determine a SCI decoding priority order of a plurality of sub-channels in the determined set of resource pools based on (1) one or more semi-persistent transmission and/or re-transmission reservations and (2) one or more priorities associated with the one or more semi-persistent transmission and/or re-transmission reservations;
perform one or more decoding attempts for a first-stage SCI in the plurality of sub-channels according to the determined SCI decoding priority order;
on condition that a number of the decoding attempts for the first-stage SCI in the plurality of sub-channels is less than or equal to a threshold number of decoding attempts, determine whether a second-stage SCI associated with the first-stage SCI is to be decoded based on information indicated by the first-stage SCI; and
on condition that the second-stage SCI is to be decoded, decode the second-stage SCI.
