Title:
HARQ-ACK FEEDBACK TIMING FOR SPS PDSCH
Document Type and Number:
WIPO Patent Application WO/2019/028857
Kind Code:
A1
Abstract:
Apparatuses, methods, and systems are disclosed for determining hybrid automatic repeat request acknowledgement ("HARQ-ACK") feedback timing for semi-persistent scheduling ("SPS") physical downlink shared channel ("PDSCH"). One apparatus (300) includes a receiver (335) that receives (805) a radio resource control ("RRC") signal from a base unit and a processor (305) that determines (810) a feedback timing for a SPS PDSCH transmission. The processor (305) uses the RRC signal to determine the feedback timing. The apparatus also includes a transmitter (330) that transmits (815) HARQ-ACK feedback to the base unit in a first slot defined by the feedback timing information. Here, the HARQ-ACK feedback indicating whether the SPS PDSCH transmission was successfully received.
