1. An apparatus comprising:
at least one processor; and
at least one non-transitory memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
receive a first grant for sidelink transmission;
determine that respective inactive states, of one or more target user equipments, at least partially overlap with the first grant for sidelink transmission, wherein the target user equipment is configured to perform sidelink discontinuous reception;
determine dropping of the first grant for sidelink transmission based, at least partially, on determining that the respective inactive states at least partially overlap with the first grant for sidelink transmission;
transmit, to a base station, a message regarding dropping of the first grant for sidelink transmission, wherein the message comprises at least one of:
an indication of a cause for the dropping of the first grant for sidelink transmission, or
an indication of information configured to enable avoidance of dropping of a grant for sidelink transmission; and
receive a second grant for sidelink transmission, wherein the second grant for sidelink transmission overlaps with at least one respective active state of the one or more target user equipment, wherein the second grant for sidelink transmission is at least partially different from the first grant for sidelink transmission.
