Method and apparatus for routing path switching in wireless communication system

A wireless device configured to operate in a wireless communication system, the wireless device comprising:

• a transceiver;
• at least one processor;
• and
• at least one memory operatively coupled to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• obtaining, through the transceiver, a configuration for a first routing identity (ID) and a second routing ID, wherein the first routing ID is related to a first routing path towards a destination node, and the second routing ID is related to a second routing path towards the destination node;
• transmitting, through the transceiver to the destination node over the first routing path on a first egress channel related to the first routing ID, a first packet comprising a payload of a packet received on an ingress channel;
• and
• based on detecting a problem of a backhaul link on the first routing path related to the first routing ID, transmitting, to the destination node over the second routing path on a second egress channel related to the second routing ID, a second packet comprising a payload of a packet received on the ingress channel,
• wherein the second packet further comprises information for a routing path switch to the second routing path.

A non-transitory computer-readable medium having recorded thereon a program that, based on being executed by at least one processor, perform operations that comprise:

• obtaining a configuration for a first routing identity (ID) and a second routing ID, wherein the first routing ID is related to a first routing path towards a destination node, and the second routing ID is related to a second routing path towards the destination node;
• transmitting, to the destination node over the first routing path on a first egress channel related to the first routing ID, a first packet comprising a payload of a packet received on an ingress channel;
• and
• based on detecting a problem of a backhaul link on the first routing path related to the first routing ID, transmitting, to the destination node over the second routing path on a second egress channel related to the second routing ID, a second packet comprising a payload of a packet received on the ingress channel,
• wherein the second packet further comprises information for a routing path switch to the second routing path.
