Information counting method and apparatus, base station, and computer storage medium

An apparatus, comprising:

• at least one processor configured to:
• determine a plurality of physical downlink control channels (PDCCHs) which are transmitted within one monitoring occasion (MO) of a serving cell and used for scheduling a plurality of physical downlink shared channels (PDSCHs), wherein hybrid automatic repeat request acknowledgements (HARQ-ACKs) of the plurality of PDSCHs are in one HARQ-ACK codebook;
• determine, according to an order of indices of serving cells to which the plurality of PDSCHs belong, values assigned to counter downlink assignment indicator (DAI counter) fields in the plurality of PDCCHs corresponding to the plurality of PDSCHs;
• for PDCCHs that schedule PDSCHs in a same serving cell, determine, according to an order of time domain positions of the PDSCHs scheduled by the PDCCHs, the values assigned to DAI counter fields in the PDCCHs that schedule PDSCHs in the same serving cell;
• and
• for PDCCHs that schedule PDSCHs in the same serving cell and with a same time domain position, determine, according to an order of indices of control resource sets (CORESETs) to which the PDCCHs belong, the values assigned to DAI counter fields in the PDCCHs that schedule the PDSCHs in the same serving cell and with the same time domain position.

A method, comprising:

• transmitting, by a terminal, hybrid automatic repeat request acknowledgements (HARQ-ACKs) of a plurality of physical downlink shared channels (PDSCHs) in one HARQ-ACK codebook,
• wherein a plurality of physical downlink control channels (PDCCHs) are transmitted within one monitoring occasion (MO) of a serving cell and used for scheduling the plurality of PDSCHs,
• wherein values assigned to counter downlink assignment indicator (DAI counter) fields in the plurality of PDCCHs corresponding to the plurality of PDSCHs, are determined according to an order of indexes of serving cells to which the plurality of PDSCHs belong,
• wherein for PDCCHs that schedule PDSCHs in a same serving cell, values assigned to DAI counter fields in the PDCCHs that schedule PDSCHs in the same serving cell are determined according to an order of time domain positions of the PDSCHs scheduled by the PDCCHs, and
• wherein for PDCCHs that schedule PDSCHs in the same serving cell and with a same time domain position, values assigned to the DAI counter fields in the PDCCHs that schedule PDSCHs in the same serving cell and with the same time domain position are determined according to an order of indices of control resource sets (CORESETs) to which the PDCCHs belong.

A terminal, comprising:

• at least one processor configured to:
• transmit, via a transmitter, hybrid automatic repeat request acknowledgements (HARQ-ACKs) of a plurality of physical downlink shared channels (PDSCHs) in one HARQ-ACK codebook,
• wherein a plurality of physical downlink control channels (PDCCHs) are transmitted within one monitoring occasion (MO) of a serving cell and used for scheduling the plurality of PDSCHs,
• wherein values assigned to counter downlink assignment indicator (DAI counter) fields in the plurality of PDCCHs corresponding to the plurality of PDSCHs, are determined according to an order of indexes of serving cells to which the plurality of PDSCHs belong,
• wherein for PDCCHs that schedule PDSCHs in a same serving cell, values assigned to DAI counter fields in the PDCCHs that schedule PDSCHs in the same serving cell are determined according to an order of time domain positions of the PDSCHs scheduled by the PDCCHs, for PDCCHs that schedule PDSCHs in a same serving cell, and
• wherein for PDCCHs that schedule PDSCHs in the same serving cell and with a same time domain position, values assigned to the DAI counter fields in the PDCCHs that schedule PDSCHs in the same serving cell and with the same time domain position are determined according to an order of indices of control resource sets (CORESETs) to which the PDCCHs belong.
