Abstract
Techniques and apparatus for providing Hybrid Automatic Repeat Request (HARQ) feedback for multiple Physical Downlink Shared Channel (PDSCH) transmissions are described. One example technique involves receiving downlink control information (DCI) that schedules multiple downlink data transmissions across multiple slots. The multiple downlink data transmissions are monitored across the multiple slots. At least one HARQ feedback scheme for acknowledging the multiple downlink data transmissions is determined. HARQ feedback for the multiple downlink data transmissions is provided according to the at least one HARQ feedback scheme.
