Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining that a first physical uplink control channel (PUCCH) resource and a second PUCCH resource at least partially overlap, where the first PUCCH resource has a payload of a first size carrying a first uplink control information (UCI) in a first format, and the second PUCCH resource has a payload of a second size carrying a second UCI in a second format. Furthermore, the first UCI and the second UCI are multiplexed to form a combined payload to be carried by the first PUCCH resource in the first format or by the second PUCCH resource in the second format. Other embodiments may be described and claimed.
