13. The UE of claim 9 , wherein the UCI is transmitted on the particular sub-slot PUCCH resource.
14. The UE of claim 9 , wherein the quantity of PUCCH repetitions is determined further based on one or more configuration messages that include a radio resource control (RRC) message.
15. The UE of claim 9 , wherein the particular sub-slot PUCCH resource is used for transmitting the UCI further based on a radio resource control (RRC) configuration.
16. The UE of claim 9 , wherein, when transmitting the UCI in the plurality of sub-slot PUCCH resources, the one or more processors are configured to:
transmit the UCI in the particular sub-slot PUCCH resource.
17. A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
receive a downlink control information (DCI) message,
the DCI message identifying a particular sub-slot physical uplink control channel (PUCCH) resource of a plurality of sub-slot PUCCH resources at which to start transmission;
determine, based at least in part on the DCI message, a quantity of PUCCH repetitions to transmit; and
transmit uplink control information (UCI) in the quantity of PUCCH repetitions, wherein each PUCCH repetition in the quantity of PUCCH repetitions is transmitted in a same PUCCH resource in each of a set of consecutive sub-slots, and wherein each PUCCH repetition in the quantity of PUCCH repetitions does not cross a slot boundary.
