Information transmission method and apparatus

An information transmission method, comprising:

• receiving Downlink Control Information (DCI) corresponding to a Physical Downlink Shared Channel (PDSCH), wherein the DCI carries a first parameter, k1 and Physical Resource Indicator (PRI), for indicating selecting a first type of Physical Uplink Control Channel (PUCCH), and the first type of PUCCH is used for receiving a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) corresponding to the PDSCH;
• transmitting the HARQ-ACK corresponding to the PDSCH according to the indication of the first parameter;
• wherein transmitting the HARQ-ACK corresponding to the PDSCH according to the indication of the first parameter, comprises:
• receiving DCIs scheduling one or more PDSCHs, acquiring one uplink unit for transmitting the HARQ-ACK corresponding to the one or more PDSCHs according to the kl carried in the DCIs, and determining which of the HARQ-ACKs of the one or more PDSCHs belong to one HARQ-ACK codebook according to the indication of the first parameter carried in the DCIs and determining a PUCCH resource corresponding to the HARQ-ACK codebook according to the PRI carried in the DCIs;
• wherein the first parameter is used for indicating a HARQ-ACK codebook to which a HARQ-ACK corresponding to a PDSCH belongs;
• wherein the k1 is used for indicating a uplink unit for transmitting a HARQ-ACK corresponding to a PDSCH, comprising:
• in a case where the PDSCH is transmitted in a unit n, the HARQ-ACK corresponding to the PDSCH is transmitted in a unit n+k1;
• wherein the PRI is used for indicating a PUCCH resource corresponding to a HARQ-ACK corresponding to a PDSCH;
• wherein the PUCCH resource corresponding to a HARQ-ACK codebook is determined according to the indication of the PRI in the last DCI corresponding to the HARQ-ACK codebook.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, wherein the computer program, when executed by a processor, implements the following operations:

• transmitting Downlink Control Information (DCI) corresponding to a Physical Downlink Shared Channel (PDSCH) to a second communication node, wherein the DCI carries a first parameter, k1 and Physical Resource Indicator (PRI);
• and
• receiving, according to an indication of the first parameter, a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) corresponding to the PDSCH;
• wherein receiving, according to the indication of the first parameter, the HARQ-ACK corresponding to the PDSCH comprises:
• transmitting DCIs scheduling one or more PDSCHs, indicating one uplink unit for receiving the HARQ-ACK corresponding to the one or more PDSCHs according to the kl carried in the DCIs, and indicating which of the HARQ-ACKs of the one or more PDSCHs belong to one HARQ-ACK codebook according to the indication of the first parameter carried in the DCIs and indicating a PUCCH resource corresponding to the HARQ-ACK codebook according to the PRI carried in the DCIs;
• wherein the first parameter is used for indicating a HARQ-ACK codebook to which a HARQ-ACK corresponding to a PDSCH belongs;
• wherein the k1 is used for indicating a uplink unit for receiving a HARQ-ACK corresponding to a PDSCH, comprising:
• in a case where the PDSCH is transmitted in a unit n, the HARQ-ACK corresponding to the PDSCH is received in a unit n+k1;
• wherein the PRI is used for indicating a PUCCH resource corresponding to a HARQ-ACK corresponding to a PDSCH;
• wherein a PUCCH resource corresponding to a HARQ-ACK codebook is determined according to the indication of the PRI in the last DCI corresponding to the HARQ-ACK codebook.
