Methods and systems for routing data through iab nodes in 5g communication networks

A method for routing data by a base station communicating with a relaying node using a backhaul link in a wireless communication system, the method comprising:

• configuring routing information included in a header of a packet in an adaption layer, the adaption layer managing data routing through the backhaul link;
• and
• transmitting, based on the routing information, the packet including the data for a user equipment to a relaying node through a communication interface, the relaying node supporting a wireless access link to the user equipment and the backhaul link to other relaying node.

A method for routing data by a relaying node communicating with a base station or other relaying node using a backhaul link in a wireless communication system, the method comprising:

• obtaining, from the base station, routing information included in a header of a packet in an adaption layer, the adaption layer managing data routing through the backhaul link;
• and
• transmitting, based on the routing information, the packet including the data for a user equipment to the other relaying node or a user equipment through a communication interface, the relaying node supporting a wireless access link to the user equipment and the backhaul link to the other relaying node.

A relaying node for communicating with a base station or other relaying node using a backhaul link in a wireless communication system, the relaying node comprising:

• a processor configured to:
• obtain, from the base station, routing information included in a header of a packet in an adaption layer, the adaption layer managing data routing through the backhaul link;
• transmit, based on the routing information, the packet including the data for a user equipment to the other relaying node or the user equipment through a communication interface, the relaying node supporting a wireless access link to the user equipment and the backhaul link to the other relaying node.
