Ultra-Reliability Design for Physical Uplink Control Channel (PUCCH) in 5th Generation (5G) New Radio (NR)

A base station comprising:

• transmitting circuitry configured to transmit a Radio Resource Control (RRC) message including first information used for configuring a number of repetitions in a time domain for a physical uplink control channel (PUCCH) format 0;
• receiving circuitry configured to receive uplink control information (UCI) using the PUCCH format 0;
• wherein the number of bits supported for the UCI using the PUCCH format 0 is selected from the group consisting of 1 bit and 2 bits;
• wherein a low-Peak to Average Power Ratio (low-PAPR) sequence is used for the PUCCH format 0;
• and,
• wherein the receiving circuitry, in a case when a first number of repetitions has been previously configured, repeatedly receives the UCI using the PUCCH format 0 in continuous symbols based on the first number of repetitions.

A mobile station communication method comprising:

• receiving a Radio Resource Control (RRC) message including first information used for configuring a number of repetitions in a time domain for a physical uplink control channel (PUCCH) format 0;
• transmitting uplink control information (UCI) using the PUCCH format 0;
• wherein the number of bits supported for the UCI using the PUCCH format 0 is selected from the group consisting of 1 bit and 2 bits;
• wherein a low-Peak to Average Power Ratio (low-PAPR) sequence is used for the PUCCH format 0;
• and,
• wherein transmitting the UCI includes, in a case when a first number of repetitions has been previously configured, repeatedly transmitting the UCI using the PUCCH format 0 in continuous symbols based on the first number of repetitions.
