Disclosed are information transmission methods and devices. In an embodiment, an information transmission method includes: determining second information including a frequency domain bandwidth set; determining a hybrid automatic repeat request acknowledge (HARQ-ACK) codebook to be transmitted according to the determined second information; and transmitting the HARQ-ACK codebook.
1. An information transmission method, comprising:
determining second information including a frequency domain bandwidth set and first information;
determining a hybrid automatic repeat request acknowledge (HARQ-ACK) codebook to be transmitted according to the determined second information; and
transmitting the HARQ-ACK codebook,
wherein the frequency domain bandwidth set is determined according to a control channel resource group to which a downlink control channel resource belongs, and a relationship between the control channel resource group and the frequency domain bandwidth set,
wherein the control channel resource group refers to one of N downlink control channel resource groups, and each of the N downlink control channel resource groups corresponds to one of N frequency domain bandwidth sets,
wherein the HARQ-ACK codebook corresponds to one of N types of HARQ-ACK codebooks, and each of the N types of HARQ-ACK codebooks corresponds to one of the N downlink control channel resource groups,
wherein the frequency domain bandwidth set refers to one of N frequency domain bandwidth sets, and each of the N frequency domain bandwidth sets corresponds to one of the N types of HARQ-ACK codebooks,
wherein N is an integer greater than or equal to 2;
wherein first information includes a time interval set between a physical downlink shared channel (PDSCH) and an HARQ-ACK codebook corresponding to the PDSCH; a time domain resource set where the PDSCH is located; a maximum number of code block groups (CBGs) included in one transmission block (TB); whether HARQ-ACK feedback bits corresponding to two TBs of one PDSCH are subjected to a bundle operation; the maximum number of TBs, or CWs included in one PDSCH.
2. The method of claim 1 , wherein the relationship between the control channel resource group and the frequency domain bandwidth set includes a first correspondence between the control channel resource group and the frequency domain bandwidth set.
3. An information transmission device, comprising at least one processor and a computer-readable storage medium; wherein the computer-readable storage medium stores an instruction, and the instruction, when executed by the at least one processor, implements an information transmission method, comprising:
determining second information including a frequency domain bandwidth set and first information;
determining a hybrid automatic repeat request acknowledge (HARQ-ACK) codebook to be transmitted according to the determined second information; and
transmitting the HARQ-ACK codebook,
wherein the frequency domain bandwidth set is determined according to a control channel resource group to which a downlink control channel resource belongs, and a relationship between the control channel resource group and the frequency domain bandwidth set,
wherein the control channel resource group refers to one of N downlink control channel resource groups, and each of the N downlink control channel resource groups corresponds to one of N frequency domain bandwidth sets,
wherein the HARQ-ACK codebook corresponds to one of N types of HARQ-ACK codebooks, and each of the N types of HARQ-ACK codebooks corresponds to one of the N downlink control channel resource groups,
wherein the frequency domain bandwidth set refers to one of N frequency domain bandwidth sets, and each of the N frequency domain bandwidth sets corresponds to one of the N types of HARQ-ACK codebooks,
wherein N is an integer greater than or equal to 2;
wherein first information includes a time interval set between a physical downlink shared channel (PDSCH) and an HARQ-ACK codebook corresponding to the PDSCH; a time domain resource set where the PDSCH is located; a maximum number of code block groups (CBGs) included in one transmission block (TB); whether HARQ-ACK feedback bits corresponding to two TBs of one PDSCH are subjected to a bundle operation; the maximum number of TBs, or CWs included in one PDSCH.
4. The device of claim 3 , wherein the relationship between the control channel resource group and the frequency domain bandwidth set includes a first correspondence between the control channel resource group and the frequency domain bandwidth set.
