Classification: CPC H | IPC H

Claim 0:
1. An apparatus for wireless communication at a first Integrated Access and Backhaul (IAB) node as an intermediate node in a multiple hop path between a donor central unit (CU) and a serving IAB node providing an access radio link channel (RLC) to a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to cause the apparatus to:
receive, from the donor CU, a first packet delay budget (PDB) parameter corresponding to an end-to-end PDB for a packet to the UE, and a second PDB parameter corresponding to a one hop PDB for the packet to the UE, the first PDB parameter for the packet being based on the end-to-end PDB between a user plane function and the UE, and the second PDB parameter indicating a backhaul radio link control (RLC) PDB for a single hop of the packet, the first PDB parameter being associated with a discard determination for the packet and the second PDB parameter being associated with scheduling the packet for transmission;
perform, at the first IAB node, a discard decision about whether to discard the packet based on the first PDB parameter corresponding to the end-to-end PDB associated with the packet; and
schedule, at the first IAB node, the packet for the transmission to a second IAB node using the second PDB parameter corresponding to the one hop PDB associated with the packet.
