Patent ID: 10951363

Abstract:
Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may be configured to transmit hybrid automatic repeat request (HARQ) feedback for a set of codewords received from a base station in a single uplink channel. In some cases, it may be appropriate for the UE to transmit individual HARQ feedback for each codeword of the set of codewords (e.g., such that the UE may be able to transmit HARQ feedback for unscheduled transmissions to provide side information to the base station), and, in other cases, it may be appropriate for the UE to transmit bundled HARQ feedback for the set of codewords. Using the techniques described herein, the base station may configure the UE to provide individual HARQ feedback or bundled HARQ feedback for a set of codewords based on one or more factors.
