11. A first device 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, cause the first device to perform operations comprising:
reserving a plurality of first sidelink transmission resources;
transmitting to a second device, sidelink data on at least one first sidelink transmission resource among the plurality of first sidelink transmission resources;
selecting a plurality of second sidelink transmission resources for a transmission of the sidelink data to the second device, based on (i) the second device failing to decode the sidelink data on the plurality of first sidelink transmission resources and (ii) the sidelink data not being transmitted to the second device on at least one second sidelink transmission resource among the plurality of first sidelink transmission resources, due to prioritization between the sidelink data and other data; and
transmitting the sidelink data to the second device, based on the plurality of second sidelink transmission resources.
