Abstract
Apparatus and methods of dynamic DAI counting and HARQ-ACK codebook generation for enhanced PDCCH transmission are disclosed. The apparatus includes: a processor that generates a common Downlink Assignment Indicator (DAI) value for a set of Physical Downlink Control Channel (PDCCH) transmissions, wherein the set of PDCCH transmissions are used to transmit first Downlink Control Information (DCI) that schedules a common Physical Downlink Shared Channel (PDSCH) transmission, and the common DAI value is generated based on a first reference PDCCH, wherein the first reference PDCCH is one of the PDCCH transmissions; a transmitter that transmits the first Downlink Control Information (DCI) with the set of PDCCH transmissions; and a receiver that receives a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) codebook with feedback information bits ordered based on a second reference PDCCH, wherein the second reference PDCCH is one of the PDCCH transmissions.
