Abstract
Apparatus and methods of Hybrid Automatic Repeat Request (HARQ) Acknowledgement (ACK) feedback for multiple Physical Downlink Control Channel (PDCCH) based multiple Transmit Receive Points (TRP) transmission are disclosed. The apparatus includes: a receiver that receives a plurality of configurations of control resource sets (CORESETs), wherein each CORESET comprises a plurality of resource blocks (RBs) in frequency domain and a plurality of symbols in time domain, and time-frequency resources identified by the CORESET are used to transmit a Downlink Control Information (DCI); a processor that determines a Hybrid Automatic Repeat Request (HARQ) Acknowledgement (ACK) feedback selected from a group consisting of: a separate HARQ-ACK feedback and a joint HARQ-ACK feedback; anda transmitter that transmits the determined HARQ-ACK feedback; wherein the separate HARQ-ACK feedback is transmitted through a plurality of uplink resources; and the joint HARQ-ACK feedback is transmitted through one uplink resource.
