1. A method of wireless communication at a user equipment (UE), comprising:
receiving a configuration of an uplink control format supporting at least three acknowledgement/negative acknowledgement (ACK/NAK) bits in a time division duplex (TDD) system for an ACK/NAK payload;
determining a quantity of payload bits to allocate to the ACK/NAK payload based on a quantity of payload bits allocated for each component carrier (CC) of a set of CCs, wherein a quantity of payload bits allocated for a given CC of the set of CCs is greater than zero when a scheduled special slot for the given CC supports downlink data transmission, and the quantity of payload bits allocated for the given CC is zero when the scheduled special slot for the given CC does not support downlink data transmission;
determining a size of the ACK/NAK payload based at least in part on the determined quantity of payload bits; and
transmitting ACK/NAK information for the set of CCs in an uplink slot based at least in part on the determined size of the ACK/NAK payload.
