Uplink Control Channel Coverage Enhancement Before Dedicated Configuration

An apparatus, comprising:

• a processor configured to, when executing instructions stored in a memory, perform operations comprising:
• receiving configuration information indicating that physical uplink control channel (PUCCH) repetition is supported, wherein the configuration information configures sub-slot based PUCCH repetition;
• and
• performing a PUCCH transmission with repetition based at least in part on the configuration information.

A method, comprising:

• by a cellular base station:
• transmitting configuration information to a wireless device indicating that physical uplink control channel (PUCCH) repetition is supported, wherein the configuration information configures sub-slot based PUCCH repetition;
• and
• receive a PUCCH transmission with repetition from the wireless device.
