## Abstract

A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine a physical uplink control channel (PUCCH) resource and a PUCCH format. The instructions are also executable to transmit uplink control information (UCI) on the PUCCH resource using the PUCCH format. If the PUCCH format is a 2-symbol short PUCCH, 1-symbol PUCCH structure is used in each symbol, and if the UCI is up to 2 bits, the UCI is repeated in two symbols using repetition of a 1-symbol PUCCH. If the PUCCH format is a 2-symbol short PUCCH, and if the UCI is more than 2 bits, the UCI is jointly encoded, and the encoded UCI bits are distributed across two symbols.

## Claims

in a case where the PUCCH format is a 2-symbol PUCCH and is up to 2 bits, the UCI is repeated in two symbols using repetition of a 1-symbol PUCCH, and
in a case where the PUCCH format is a 2-symbol PUCCH and is more than 2 bits, the UCI is jointly encoded, the encoded UCI bits are distributed across two symbols, and if the UCI includes HARQ-ACK and scheduling request (SR), SR bits are appended to HARQ-ACK bits and the HARQ-ACK bits and the SR bits are jointly encoded.

### Claim 2

A base station, comprising:
a processor; and
a memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:
