Techniques and apparatuses for forwarding in multi-hop wireless networks via multi-layer tunneling and centralized control

A method of wireless communication performed by a network node, comprising:

• receiving first configuration information identifying a first flow identifier pertaining to a device, wherein the first configuration information further identifies a first tunnel identifier associated with a first tunnel, and wherein the first configuration information identifies at least one of a first radio bearer identifier associated with a first radio bearer or a second tunnel identifier associated with a second tunnel;
• providing data, associated with the first flow identifier, in association with the first tunnel identifier and via the first radio bearer or the second tunnel to the device, based at least in part on the first radio bearer identifier or the second tunnel identifier;
• identifying second configuration information pertaining to a second flow identifier;
• and
• providing other data based at least in part on the other data being associated with the second flow identifier.

A method of wireless communication performed by a network node, comprising:

• receiving a request including a relay identifier for a wireless communication relay and a device identifier for a device;
• selecting at least one of a first radio bearer or a first tunnel, associated with a first tunnel identifier, for communication of data with the device via the wireless communication relay;
• providing, to the wireless communication relay, first configuration information for a second radio bearer and a second tunnel associated with a second tunnel identifier,
• wherein the wireless communication relay is configured to communicate the data from at least one of the first radio bearer or the first tunnel to at least one of the second radio bearer or the second tunnel;
• and
• providing second configuration information identifying at least one of the first radio bearer or the first tunnel identifier.

A wireless communication relay, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• receive first configuration information identifying a first mapping between a first radio bearer and a first tunnel identifier;
• obtain a second mapping between a second radio bearer and at least one of the first radio bearer or the first tunnel identifier;
• transmit first data, received on the first radio bearer, on the second radio bearer,
• wherein the first data is transmitted with the first tunnel identifier;
• receive second configuration information identifying a third mapping between a third radio bearer and a second tunnel identifier;
• and
• transmit second data, received on the third radio bearer, on the second radio bearer.
