Technology for an eNodeB operable to control communications at a relay user equipment (UE) is disclosed. The eNodeB can select the relay UE to relay proximity services (ProSe) traffic between the eNodeB and a remote UE based on one or more relay quality indicators associated with the relay UE. The eNodeB can communicate, to the relay UE, control signaling to configure one or more orthogonal timelines to cause the relay UE to resolve ProSe communications between the relay UE and the remote UE that conflict with uplink hybrid automatic repeat request (HARQ) acknowledgement (ACK) or negative acknowledgement (NACK) transmissions from the relay UE to the eNodeB.
