TECHNIQUES FOR DETERMINING GROUP IDENTIFICATION AND A DOWNLINK ASSIGNMENT INDEX FOR ENHANCED DYNAMIC CODEBOOKS

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more downlink control information (DCI) messages scheduling downlink transmissions associated with different groups, where feedback for the downlink transmissions may be transmitted during a same time period. The UE may index the received DCI messages based on a set of serving cell indices and monitoring occasion indices, and the UE may select a DCI message from the indexed DCI messages. The UE may identify, based on an index associated with the DCI messages, a first DCI message that has a format that includes a group index field. The UE may identify, from the group index field of the identified DCI message, a group index value that indicates a first group, and the UE may transmit a feedback message that includes at least a codebook that is based on the group index value.
