1. A method of operating an integrated access and backhaul (IAB) node comprising an IAB mobile terminal (MT) and an IAB distributed unit (DU), comprising:
receiving, at the IAB MT from a parent node, a conditional grant associated with a set of conditional parameters for triggering an uplink transmission from the IAB MT to the parent node on (i) both a first subset and a second subset of a plurality of candidate resources configured by the conditional grant when a first triggering event is detected and (ii) only on the first subset of the plurality of candidate resources without any uplink transmission being transmitted by the IAB node on the second subset of the plurality of candidate resources when a second triggering event is detected, the first and second triggering events based at least in part on a communication status of the IAB DU subsequent to receipt of the conditional grant;
detecting, after the conditional grant is received, the second triggering event for triggering the conditional grant with at least one conditional parameter of the set of conditional parameters; and
performing the uplink transmission only on (ii) the first subset of the plurality of candidate resources without any uplink transmission being transmitted by the IAB node on the second subset of the plurality of candidate resources in accordance with the at least one conditional parameter.
