Abstract
A method for determining time interval, a time interval indication method, and an HARQ-ACK sending method. The method for determining time interval includes: receiving, by a terminal, a plurality of SPS configurations, different SPS configurations having different periods; and determining, by a terminal, a time interval between receiving time of a PDSCH of each of the SPS configurations and sending time of an HARQ-ACK for the PDSCH according to a corresponding period in each of the SPS configurations, the corresponding period is positively correlated with the time interval.
Claims19
A method for determining time interval, comprising:
- receiving, by a terminal, a plurality of semi-persistent scheduling (SPS) configurations, different SPS configurations having different periods;
- and
- determining, by the terminal, a time interval between receiving time of a physical downlink shared channel (PDSCH) of each of the SPS configurations and sending time of a hybrid automatic repeat request-acknowledgement (HARQ-ACK) for the PDSCH according to a corresponding period in each of the SPS configurations,
- wherein the corresponding period is positively correlated with the time interval.
A time interval indication method, comprising:
- sending, by a base station, a plurality of semi-persistent scheduling (SPS) configurations and indication information to a terminal, different SPS configurations having different periods, the indication information being configured to indicate the terminal to determine a time interval between receiving time of a physical downlink shared channel (PDSCH) and sending time of a hybrid automatic repeat request-acknowledgement (HARQ-ACK) for the PDSCH according to the period of each of the SPS configurations, and the period being positively correlated with the time interval.
A hybrid automatic repeat request-acknowledgement (HARQ-ACK) sending method, wherein the method is applicable to a terminal configured with multiple semi-persistent scheduling (SPS) configurations, and comprises:
- determining that physical uplink control channel (PUCCH) resources of HARQ-ACKs for different PDSCHs configured based on multiple SPS configurations overlap one another in a time domain, the PUCCH resources being configured to send the HARQ-ACKs;
- determining a target HARQ-ACK for a PDSCH based on a selected SPS configuration in the multiple SPS configurations;
- and
- sending the target HARQ-ACK on a target PUCCH resource corresponding to the target HARQ-ACK.
