Delay bounds for scheduling priority and packet discard in an integrated access and backhaul network

A method of wireless communication at a first Integrated Access and Backhaul (IAB) node, comprising:

• receiving a first delay parameter and a second delay parameter associated with a packet, the first delay parameter being associated with a discard determination for the packet and the second delay parameter being associated with scheduling the packet for transmission;
• performing a discard decision based on the first delay parameter associated with the packet;
• and
• scheduling the packet for the transmission to a second IAB node or a user equipment (UE) using the second delay parameter associated with the packet.

An apparatus of wireless communication at a central unit (CU) of an integrated access and backhaul (IAB) network, comprising:

• a memory;
• and
• at least one processor coupled to the memory, the memory and the at least one processor configured to:
• indicate, to an IAB node, a first delay parameter for determining whether to discard a packet and a second delay parameter for scheduling the packet;
• and
• send the packet for transmission to a user equipment (UE) via one or more IAB nodes including the IAB node.
