Triggering relay transmission using a physical downlink shared channel

A method of wireless communication performed by a relay device, the method comprising:

• receiving a first Physical Downlink Shared Channel (PDSCH) communication;
• determining, from the first PDSCH communication, a first combined transport block including a first header and a plurality of components, the plurality of components including a first control component associated with a first user equipment (UE) and the first header including routing information associated with the first control component;
• generating a first transport block that includes the first control component;
• determine, based on the routing information associated with the first control component, at least one node that is part of a route to the first UE;
• and
• transmitting the first transport block to the at least one node.

A wireless communication base station, comprising:

• at least one memory;
• at least one transceiver;
• and
• at least one processor coupled to the at least one memory and the at least one transceiver, the at least one processor configured to:
• generate a combined transport block including a plurality of components and routing information indicating at least one route associated with a first user equipment (UE);
• determine a first header, a first control component, and a first data component associated with the first UE, the first header including routing information associated with the first control component and indicating at least one node that is part of a route to the first UE, wherein the control component and the data component are included in the plurality of components in the combined transport block, and wherein the first header is included in a plurality of headers in the combined transport block;
• and
• transmit, via the at least one transceiver, the combined transport block in a Physical Downlink Shared Channel (PDSCH) communication for receipt by the first UE.
