Disclosed are methods, systems, apparatus, and computer programs for determining in a new radio (NR) integrated access and backhaul (IAB) system a start symbol of available soft resources of an IAB node. In one aspect, a method includes determining, by a distributed unit (DU) of the IAB node and based on a configuration signal received from a central unit (CU) of an IAB donor, a configuration of available soft resources for a child link of the IAB node. The method further includes determining, based on the configuration of available soft resources, a start symbol of the available soft resources. The method also includes using the available soft resources for one or more child link transmissions starting from the start symbol. |
