Abstract
A method for feeding back a hybrid automatic repeat request-acknowledgment (HARQ-ACK), performed by a terminal device, includes: receiving first indication information, wherein the first indication information is configured to indicate M non-continuous time units; receiving N physical downlink shared channels (PDSCHs) respectively over the M non-continuous time units; and transmitting HARQ-ACK feedback information corresponding to the N PDSCHs; wherein M and N are positive integers greater than 1, and N is less than or equal to M.

A method for feeding back a hybrid automatic repeat request-acknowledgment (HARQ-ACK), performed by a terminal device, comprising:
- receiving first indication information, wherein the first indication information is configured to indicate M non-continuous time units;
- receiving N physical downlink shared channels (PDSCHs) respectively over the M non-continuous time units;
- and
- transmitting HARQ-ACK feedback information corresponding to the N PDSCHs;
- wherein transmitting the HARQ-ACK feedback information corresponding to the N PDSCHs comprises:
- transmitting the HARQ-ACK feedback information corresponding to the N PDSCHs based on a specified codebook in a same physical uplink control channel (PUCCH) resource, wherein HARQ-ACK feedback information corresponding to different PDSCHs correspond to different bits or a same bit in the specified codebook;
- or
- transmitting the HARQ-ACK feedback information corresponding to the N PDSCHs based on different PUCCH resources, wherein a number of the different PUCCH resources is same as a number of time unit groups into which the M non-continuous time units are divided,
- wherein M and N are positive integers greater than 1, and N is less than or equal to M.
A method for feeding back a hybrid automatic repeat request-acknowledgment (HARQ-ACK), performed by a network device, comprising:
- transmitting first indication information, wherein the first indication information is configured to indicate M non-continuous time units;
- transmitting N physical downlink shared channels (PDSCHs) respectively over the M non-continuous time units;
- and
- receiving HARQ-ACK feedback information corresponding to the N PDSCHs;
- wherein receiving the HARQ-ACK feedback information corresponding to the N PDSCHs comprises:
- receiving the HARQ-ACK feedback information corresponding to the N PDSCHs based on a specified codebook in a same physical uplink control channel (PUCCH) resource, wherein HARQ-ACK feedback information corresponding to different PDSCHs correspond to different bits or a same bit in the specified codebook;
- or
- receiving the HARQ-ACK feedback information corresponding to the N PDSCHs based on different PUCCH resources, wherein a number of the different PUCCH resources is same as a number of time unit groups into which the M non-continuous time units are divided,
- wherein M and N are positive integers greater than 1, and N is less than or equal to M.
A terminal device, comprising:
- a processor;
- and
- a memory storing instructions executable by the processor,
- wherein the processor is configured to:
- receive first indication information, wherein the first indication information is configured to indicate M non-continuous time units;
- receive N physical downlink shared channels (PDSCHs) respectively over the M non-continuous time units;
- and
- transmit hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback information corresponding to the N PDSCHs;
- wherein the processor is further configured to:
- transmit the HARQ-ACK feedback information corresponding to the N PDSCHs based on a specified codebook in a same physical uplink control channel (PUCCH) resource, wherein HARQ-ACK feedback information corresponding to different PDSCHs correspond to different bits or a same bit in the specified codebook;
- or
- transmit the HARQ-ACK feedback information corresponding to the N PDSCHs based on different PUCCH resources, wherein a number of the different PUCCH resources is same as a number of time unit groups into which the M non-continuous time units are divided,
- wherein M and N are positive integers greater than 1, and N is less than or equal to M.
