Techniques are described for wireless communication at a user equipment (UE). One method includes receiving a downlink grant for a downlink transmission; transmitting channel quality feedback at a first time triggered by receipt of the downlink grant, the first time occurring during a first transmission time interval (TTI); and transmitting acknowledgement/negative-acknowledgement (ACK/NACK) feedback for the downlink transmission at a second time triggered by receipt of the downlink grant, the second time occurring during a second TTI, and the second TTI occurring later in time than the first TTI.
