Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that a scheduling request (SR) is to be transmitted on a first uplink control channel having a first transmission time interval (TTI) duration and identify that acknowledgment/negative acknowledgment (ACK/NACK) information is scheduled for transmission on a second uplink control channel having a second TTI duration greater than the first TTI duration, where the first uplink control channel and the second uplink control channel overlap in time. The UE may determine that the ACK/NACK information is to be transmitted with the SR on the first uplink control channel based on the overlapping first uplink control channel and second uplink control channel, and may determine resources of the first uplink control channel to be used for transmission of SR and ACK/NACK information. The UE may transmit the SR and the ACK/NACK information on the determined resources.
