Abstract
Methods and apparatus for uplink control enhancement in wireless communications are disclosed. In an example, a method includes receiving information related to a set of downlink SPS configurations, receiving downlink SPS transmission(s) based on the received information, determining a payload of UCI for transmission over an uplink channel, the payload comprises a set of HARQ feedback bits based on the received information, determining that at least one triggering condition for segmenting the set of HARQ feedback bits is satisfied, determining at least a portion of the set of HARQ feedback bits based on at least a downlink SPS configuration of the set of downlink SPS configurations, wherein the determined portion of the set of HARQ feedback bits corresponds to a respective subset of the received downlink SPS transmission(s), and transmitting at least the determined portion of the set of HARQ feedback bits using the uplink channel.
