Methods, systems, and devices for wireless communications are described. The base station may transmit one or more transmissions to a first user equipment (UE) and a second UE, and the one or more transmissions may include a first grant for the first UE and a second grant for the second UE. The first grant may assign a first uplink resource for a source data transmission and a first downlink resource for feedback by the base station associated with the source data transmission. The second grant may assign a second uplink resource for a relay data transmission and a second downlink resource for feedback by the base station associated with the relay data transmission. The first UE and the relay UE may communicate with the other of the first UE and the second UE or the base station, or both, based on the first and second grant.
