1. A communication device of a relay node for wireless communication, comprising:
a first interface configured to obtain, from a first wireless node and via a first wireless link, a first communication carrying a payload;
a processing system configured to generate, using digital processing, a second communication, wherein the second communication is different than the first communication, and wherein the second communication carries the payload of the first communication;
the first interface or a second interface configured to output, to a second wireless node and via a second wireless link, the second communication;
the processing system configured to monitor for an indication of whether the second wireless node received the second communication;
the first interface or the second interface configured to output, to the first wireless node, a third communication that includes:
a first feedback indication of whether the second wireless node received the second communication, and
a second feedback indication that the relay node received the first communication;
wherein the first interface or the second interface, to output the third communication, is configured to:
forward the indication of whether the second wireless node received the second communication;
wherein the first communication includes a shared channel that carries control information for forwarding the indication; and
wherein the control information indicates a resource for the third communication or a configuration for the third communication.
