1. In an integrated access and backhaul (IAB) network comprising an IAB node, a method comprising:
performing, by an adaptation layer of the IAB node, an end-to-end header compression on one or more headers of a packet for transmission over an end-to-end backhaul link in the IAB network between the IAB node and a destination IAB access node, wherein performing header compression on the one or more headers comprises:
determining a load status of the IAB network with respect to a number of contexts required by UE bearers served by the IAB network; and
determining, based on the load status, a context identifier of an ROHC channel,
wherein a number of bits of the context identifier is one of 8 bits, 16 bits, or 24 bits; and
transmitting the packet with the one or more compressed headers over the end-to-end backhaul link to the destination IAB access node.
