The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: Methods, systems, and devices for wireless communication are described. A Type-I codebook, such as a semi-static fixed size codebook, may be designed to be used for reporting feedback for messages scheduled by a single downlink control information (DCI) message in communications where feedback multiplexing may be avoided. Additionally, or alternatively, a network entity and a user equipment (UE) implementing a Type-I codebook may consider overlapping feedback resources for different DCI messages as an error case. By way of another example, a network entity may allow overlap in scheduling, and a UE may bundle feedback into a single bit. A Type-I codebook payload size may be based on a quantity of code-block groups (CBGs) or a quantity of codewords in a transport block (TB), and may be used for fallback DCI messages. Further, puncturing or rate matching operations may be performed when provision of resources overlap with uplink transmissions.
