Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may act as a relay device and receive a message from a source device. The message may include a latency indicator. The UE may identify a delay-tolerance metric associated with the message based on the latency indicator. The UE may identify, for each air interface of a set of air interfaces, a cost metric associated with transmitting the message. The UE may select an air interface from the set of air interfaces based on the delay-tolerance metric and the cost metric. The UE may transmit the message to a destination device on the selected air interface.
