GENERATING A FEEDBACK CODEBOOK

Abstract:

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, an indication of a configuration for transmitting subslot-based feedback messages (e.g., via an uplink channel) associated with downlink transmissions (e.g., received via a downlink channel). In some cases, the UE and base station may generate a feedback codebook for the feedback messages according to a subslot-based codebook generation procedure. For example, the UE and base station may generate the feedback codebook based on a quantity of downlink transmission opportunities ending during each subslot of the uplink channel. The UE may then transmit, to the base station via the uplink channel, the feedback messages in accordance with the feedback codebook.
