The present invention discloses a method, system, apparatus and computer program for determining the availability of soft time domain resources for a node in an integrated access and backhaul (IAB) network. In one aspect, a method includes receiving a radio resource control (RRC) message from an IAB donor; determining, based on the RRC message, whether soft time domain resources are available for an IAB node; and in response to determining that the soft time domain resources are available, Transmissions with child nodes are scheduled using available soft time domain resources. |
