Pucch design for unlicensed band operation at mmwaves

An apparatus, comprising:

• one or more processors;
• and
• one or more memories including computer program code,
• the one or more memories and the computer program code configured to, with the one or more processors, cause the apparatus to at least:
• determine information received from a communication network comprising a physical uplink control channel resource set indication and an indication of subcarrier spacing used for a physical uplink control channel;
• based on the information, determine at least one of a size or allocation of at least one physical uplink control channel resource associated with the physical uplink control channel resource set;
• and
• transmit control information associated with the physical uplink control channel to the communication network using at least the determined at least one of size or allocation of the at least one physical uplink control channel resource.
