QOS INFORMATION EXCHANGE TO SETUP A BACKHAUL ROUTING PATH IN IAB

Abstract:

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus of a first network node are provided. The first network node may send quality of service (QoS) information and a request to a second network node to configure, based on the QoS information, a backhaul routing path for traffic between the first network node and a third network node via the second network node, the third network node having a signaling connection with the first network node. The first network node may communicate, with the second network node in response to the request, QoS mapping information. The first network node may configure an Internet protocol (IP) header of an IP packet based on the communicated QoS mapping information. The first network node may send the IP packet with the configured header to the second network node for routing through the backhaul routing path.
