Abstract

One or more aspects of physical uplink control channel (PUCCH) repetition is disclosed. In a particular implementation, a method of wireless communication includes receiving, by a user equipment (UE), downlink control information (DCI) including a physical uplink control channel resource indicator (PRI) field codepoint. The method also includes determining, based on the PRI field codepoint, whether to transmit a PUCCH repetition within a slot position using a single PUCCH resource or transmit multiple PUCCH repetitions within the slot position using multiple PUCCH resources. The method further includes transmitting multiple PUCCH repetitions within the slot position using the multiple PUCCH resources responsive to determining to transmit the multiple PUCCH repetitions within the slot position using the multiple PUCCH resources.
