Title: IDENTIFYING A RESOURCE FOR TRANSMITTING A FIRST UPLINK CHANNEL
Abstract:
Apparatuses, methods, and systems are disclosed for communicating a short-duration uplink channel. One apparatus 400 includes a transceiver 425 that receives 1005 a downlink scheduling assignment message from a base unit 110, the scheduling message assigning resources for reception of a TB. The apparatus 400 includes a processor 405 that identifies 1010 a set of uplink resources in a slot and determines 1015 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 425 transmits 1020 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.
