Methods and apparatus of PDSCH processing procedure time derivation for HARQ-ACK feedback of PDSCH scheduled by enhanced PDCCH E

A network equipment (NE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the NE to:
• transmit a physical downlink control channel (PDCCH) with a plurality of repetitions and a physical downlink shared channel (PDSCH) that is scheduled by the PDCCH with the plurality of repetitions, the plurality of repetitions including a first PDCCH and a second PDCCH;
• derive a PDSCH processing procedure time based on at least one of:
• a larger one of a first number of overlapping symbols between the first PDCCH and the PDSCH and a second number of overlapping symbols between the second PDCCH and the PDSCH;
• or
• an additional processing time for processing of the PDCCH transmitted with the plurality of repetitions;
• and
• receive a valid hybrid automatic repeat request acknowledgement (HARQ-ACK) message no earlier than the PDSCH processing procedure time.

A user equipment (UE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• receive a physical downlink shared channel (PDSCH) that is scheduled by a physical downlink control channel (PDCCH) transmitted with a plurality of repetitions, the plurality of repetitions including a first PDCCH and a second PDCCH;
• derive a PDSCH processing procedure time based on at least one of:
• a larger one of a first number of overlapping symbols between the first PDCCH and the PDSCH and a second number of overlapping symbols between the second PDCCH and the PDSCH;
• or
• an additional processing time for processing the PDCCH transmitted with the plurality of repetitions;
• and
• transmit a valid hybrid automatic repeat request acknowledgement (HARQ-ACK) message no earlier than the PDSCH processing procedure time.

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• receive a physical downlink shared channel (PDSCH) that is scheduled by a physical downlink control channel (PDCCH) transmitted with a plurality of repetitions, the plurality of repetitions including a first PDCCH and a second PDCCH;
• derive a PDSCH processing procedure time based on at least one of:
• a larger one of a first number of overlapping symbols between the first PDCCH and the PDSCH and a second number of overlapping symbols between the second PDCCH and the PDSCH;
• or
• an additional processing time for processing the PDCCH transmitted with the plurality of repetitions;
• and
• transmit a valid hybrid automatic repeat request acknowledgement (HARQ-ACK) message no earlier than the PDSCH processing procedure time.
