Apparatuses, methods, and systems are disclosed for communicating a short-duration uplink channel. One apparatus includes a transceiver that receives a downlink scheduling assignment message from a base unit, the scheduling message assigning resources for reception of a TB. The apparatus includes a processor that identifies a set of uplink resources in a slot and determines a first uplink resource from within the set. Here, selecting the first uplink resource is based on: a RB index of a first assigned FRU of the TB, a lowest CCE index of the scheduling message, a HARQ-ACK feedback delay, and / or a HARQ-ACK resource index / offset indicated in the scheduling message. Additionally, the transceiver transmits a first uplink channel conveying at least HARQ-ACK feedback for the TB on the first uplink resource, wherein the first uplink channel comprises one or two symbols in the slot.
