Resource scheduling for a relay-based sidelink network

An apparatus for wireless communications at a first relay node, comprising:

• a processor;
• and
• a memory coupled with the processor and storing instructions operable, when executed by the processor, to cause the apparatus to:
• receive, from a donor network node, a relay network message indicating configuration information associated with a sidelink relay network, the sidelink relay network including a set of relay nodes and a set of destination nodes, the set of relay nodes including the first relay node;
• transmit, to one or both of the donor network node or one or more other relay nodes in the set of relay nodes, a queue report message indicating one or more channel characteristics and queue information;
• receive, from the donor network node, a resource allocation message indicating a group of resources, based at least in part on the queue report message, for communicating with the set of destination nodes;
• and
• transmit, to one or more destination nodes in the set of destination nodes via one or more respective sidelink channels, data via one or more resources of the group of resources.

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

• transmitting, to a group of relay nodes, a relay network message indicating configuration information associated with a sidelink relay network, the sidelink relay network including a set of relay nodes of the group of relay nodes and a set of destination nodes;
• receiving, from each relay node in the set of relay nodes, a respective queue report message indicating one or more channel characteristics and queue information;
• and
• transmitting, based on receiving the queue report messages from the set of relay nodes, a resource allocation message to the set of relay nodes that indicates a group of resources allocated among the set of relay nodes for communicating with the set of destination nodes via respective sidelink channels.
