The information transmission method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of an information transmission method provided in an embodiment of the present application, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 21: the terminal acquires UCI to be transmitted.

In this embodiment, the UCI to be transmitted may include, but is not limited to, CSI, HARQ-ACK feedback information, and the like. The HARQ-ACK feedback information may include, but is not limited to, Coding Block Group (CBG) -based HARQ-ACK feedback information, Transport Block (TB) -based HARQ-ACK feedback information, and the like.

Step 22: and the terminal compresses the UCI to be transmitted to obtain UCI compression information.

Optionally, when compressing the UCI to be transmitted, the terminal may compress part or all of the information in the UCI to be transmitted, and may selectively discard part of the information in the UCI to be transmitted, which is not limited in this embodiment.

Step 23: and the terminal transmits the UCI compressed information.

According to the information transmission method, after the terminal acquires the UCI to be transmitted, the terminal can compress the UCI to be transmitted to obtain UCI compressed information and transmit the UCI compressed information. Therefore, by compressing the UCI to be transmitted, the bit information in the transmission process of the UCI can be reduced, and the transmission capability of the UCI is improved.

In the embodiment of the present application, the terminal may compress the UCI to be transmitted in different manners, which is described in detail below.

1) When compressing the UCI to be transmitted, the terminal may discard part or all of the CSI in the UCI to be transmitted.

For example, the terminal may discard unnecessary CSI in the UCI to be transmitted.

2) When compressing the UCI to be transmitted, the terminal may use HARQ-ACK bundling to bundle HARQ-ACK feedback information in the UCI to be transmitted.

For example, for HARQ-ACK bundling, the terminal may perform logical and operation on HARQ-ACK feedback information corresponding to the same data stream in the UCI to be transmitted, so as to obtain 1-bit or 2-bit ACK/NACK information.

3) When compressing the UCI to be transmitted, the terminal can compress HARQ-ACK feedback information based on the CBG in the UCI to be transmitted.

In an embodiment, if the feedback of the CBG is configured, the terminal may discard all HARQ-ACK feedback information based on the CBG in the UCI to be transmitted. Further, the terminal may instead use the HARQ information based on the TB feedback, so that the terminal does not perform HARQ-ACK feedback for CBG, but only performs HARQ-ACK feedback for TB.

In another embodiment, if the feedback of the CBG is configured, the terminal may compress HARQ-ACK feedback information based on the CBG in part of the UCI to be transmitted. For example, the CBG-based HARQ-ACK feedback information is 8 bits, and may be compressed every two bits to obtain 4 bits of transmission information.

In the embodiment of the application, the terminal can adopt different modes to judge whether a transmission mode of compressing the UCI is adopted. Optionally, the terminal may compress the UCI to be transmitted under the condition that at least one of the following conditions is satisfied:

1) the code rate (code) of UCI to be transmitted is higher than a first code rate threshold value;

optionally, the first code rate threshold may be a predetermined value, or may be a value configured in a Physical Uplink Control Channel (PUCCH) Resource (PUCCH-Resource) by a network side device, that is, a higher layer. For example, the network side device may configure a fixed first code rate threshold in each PUCCH resource, and the first code rate thresholds configured in different PUCCH resources may be the same or different; or, the network side device may configure one fixed first code rate threshold value for all PUCCH resources.

In an embodiment, after obtaining the UCI to be transmitted and selecting the PUCCH resource, the terminal may determine whether the code rate of the UCI to be transmitted is higher than a first code rate threshold configured in the PUCCH resource, and determine to use a transmission method of compressing the UCI and compress the UCI to be transmitted under the condition that the code rate of the UCI to be transmitted is higher than the first code rate threshold, so that UCI compression information is lower than the first code rate threshold.

2) The bit number of the UCI to be transmitted is larger than a first bit threshold value;

optionally, the first bit threshold may be a predetermined value, or may be a value configured in the PUCCH resource by the network side device, that is, a higher layer. For example, the network side device may configure a fixed first bit threshold in each PUCCH resource, and the first bit thresholds configured in different PUCCH resources may be the same or different; or, the network side device may configure one fixed first bit threshold value for all PUCCH resources.

In an embodiment, after obtaining the UCI to be transmitted and selecting the PUCCH resource, the terminal may determine whether the bit number of the UCI to be transmitted is greater than a first bit threshold configured in the PUCCH resource, and determine to compress the UCI to be transmitted in a transmission manner of compressing the UCI under the condition that the code rate of the UCI to be transmitted is greater than the first bit threshold, so that UCI compression information is smaller than the first bit threshold.

3) The bit number of UCI to be transmitted is larger than a second bit threshold value, and the PUCCH format indicated by the physical uplink control channel Resource Indication (PRI) acquired by the terminal is PUCCH format0 or PUCCH format 1;

optionally, the second bit threshold is 2, that is, if the bit number of the UCI to be transmitted is greater than 2bits and the PUCCH format indicated by the PRI is PUCCH format0 or PUCCH format1, the terminal compresses the UCI to be transmitted.

4) The bit number of HARQ-ACK feedback indicated by a Downlink Assignment Index (DAI) in an Uplink grant (UL grant) is less than the bit number of HARQ-ACK feedback information to be transmitted in the UCI to be multiplexed on a Physical Uplink Shared Channel (PUSCH);

in this case 4), the terminal may compress the HARQ-ACK feedback information to be multiplexed on the PUSCH in the UCI to be transmitted, so that the bit number of the compressed information is less than or equal to the bit number of the HARQ-ACK feedback indicated by the DAI in the UL grant.

5) The PUCCH resource indicated by the PRI acquired by the terminal is configured to be used for transmission of UCI compression information;

6) a first indication field in Downlink Control Information (DCI) acquired by a terminal indicates a transmission mode using compressed UCI.

Optionally, the DCI may include, but is not limited to, any one of the following:

downlink or uplink scheduling of the DCI of the data;

a DCI with no data scheduled but with Aperiodic Channel State Information (A-CSI) reports scheduled;

group common (DCI); optionally, a Cyclic Redundancy Check (CRC) in the group common DCI may be scrambled by a Transmit Power Control-PUCCH-Radio Network Temporary Identity (TPC-PUCCH-RNTI).

Optionally, the first indication field may be further configured to indicate a manner of compressing the UCI to be transmitted, that is, indicate which compression manner is used to compress the UCI to be transmitted.

Optionally, the first indication field may include, but is not limited to, at least one of the following: PRI, DAI, new indication field. For example, the new indication field is x (x ≧ 1) bit, and is used to indicate whether to compress the UCI to be transmitted and/or the way to compress the UCI to be transmitted.

In the embodiment of the application, in order to accurately realize the compression process, when the HARQ-ACK bundling mode is adopted to bundle the HARQ-ACK feedback information in the UCI to be transmitted, the terminal may first determine a target bundling size, and bundle the HARQ-ACK feedback information in the UCI to be transmitted according to the target bundling size.

Optionally, the process of determining the target binding size may include any one of the following:

a) and the terminal determines the bundling size configured in the PUCCH resource by the network side equipment as the target bundling size.

In a), the network side device may configure a fixed bundling size (or referred to as a bundling size) in each PUCCH resource, and the bundling sizes configured in different PUCCH resources may be the same or different. Or, the network side device may configure one fixed bundling size for all PUCCH resources, so that the terminal determines the target bundling size.

In an implementation manner, after acquiring the UCI to be transmitted and selecting the PUCCH resource, the terminal may determine a target bundling size according to the bundling size configured in the PUCCH resource, and bundle HARQ-ACK feedback information in the UCI to be transmitted according to the target bundling size.

b) And the terminal determines the target binding size according to the bit number of the UCI to be transmitted.

Optionally, in b), the terminal may calculate the target binding size C by using the following formula:

C＝ceil(M/N)

wherein, M represents the bit number of UCI to be transmitted, N represents the third bit threshold value, and ceil represents rounding up. The third bit threshold value may be predetermined or configured at a higher layer.

c) And the terminal selects and obtains the target binding size from the bit number value set, wherein the bit number value set is configured in the PUCCH resources by the network side equipment.

Optionally, in c), the network side device may configure one bit number value set in each PUCCH resource, and the bit number value sets configured in different PUCCH resources may be the same or different. Alternatively, the network side device may configure one bit number value set for all PUCCH resources.

In an embodiment, after obtaining the UCI to be transmitted and selecting the PUCCH resource, the terminal may select a value from a bit number value set configured in the PUCCH resource as a target bundling size, and bundle HARQ-ACK feedback information in the UCI to be transmitted according to the target bundling size, so that a code rate of bundled UCI compression information is lower than a configured maximum code rate (maxCodeRate) threshold value.

Optionally, when the HARQ-ACK bundling manner is adopted to bundle HARQ-ACK feedback information in the UCI to be transmitted, the HARQ-ACK feedback information corresponds to a service, and/or the HARQ-ACK feedback information corresponds to a HARQ-ACK priority. For example, the terminal can only bundle the HARQ-ACK feedback information corresponding to one service and/or one HARQ-ACK priority in a HARQ-ACK bundling manner. Wherein, the HARQ-ACK priority may be a type priority or a feedback priority, etc.

In this embodiment of the application, in order to ensure the UCI transmission, the compressing the UCI to be transmitted may include: and the terminal determines the target compression ratio special number and compresses the UCI to be transmitted according to the target compression ratio special number to obtain UCI compression information.

Optionally, the determining the target compression ratio number may include any one of:

1) and the terminal determines a target compression bit number according to the compression ratio number configured by the network side equipment.

In this 1), the network side device may configure one compressed minimum compression bit number in each PUCCH resource, and the minimum compression bit numbers configured in different PUCCH resources may be the same or different, so that after the terminal selects a PUCCH resource, the terminal determines a target compression ratio bit number according to the minimum compression ratio bit number configured in the selected PUCCH resource, for example, determines the minimum compression ratio bit number as the target compression bit number.

2) And the terminal determines a target compression bit number according to the transmission capacity supported by the terminal.

In this 2), the terminal may determine the target number of compression bits directly according to the transmission capability supported by the terminal itself. Or, after the terminal acquires the number of compression bits configured by the network-side device, if the number of compression bits configured by the network-side device exceeds the transmission capability supported by the terminal, for example, the number of compression bits configured by the network-side device is 11, and the terminal only supports transmission of 10-bit information, the target number of compression bits may be determined according to the transmission capability supported by the terminal.

Optionally, if the bit number of the UCI to be transmitted is M and the target compression bit number is X, the compressing the UCI to be transmitted according to the target compression ratio bit number to obtain UCI compression information may include any one of the following:

the method comprises the steps that a terminal I reserves first X-1 bit information in UCI to be transmitted and compresses last M-X + 1bit information in the UCI to be transmitted into 1bit information;

for example, when UCI compression is performed by using HARQ-ACK bundling, a minimum compressed bit number X, that is, a target compression ratio bit number X, may be introduced, and information of the first X-1 bits is retained, and information of M-X +1 bits is compressed to information of 1bit after bundling.

Filling X-Y bit information behind the initial compression information of the Y bit by the terminal II; the initial compression information is obtained by performing initial compression on UCI to be transmitted, and Y is smaller than X. That is, without changing the compression mechanism, if the UCI compressed information obtained by the initial compression is Y bits and Y is smaller than X, the terminal may pad (padding) the X-Y bits of information after the Y bits of initial compressed information to obtain X bits of compressed information.

Optionally, the information of the X-Y bits may take a value of 0 or 1.

It should be noted that, in the embodiment of the present application, for obtaining UCI compression information through compression and selecting a resource for transmitting the UCI compression information from a PUCCH resource set, UCI compression may be performed first and then resource selection is performed, or resource selection may be performed first and then UCI compression is performed, which is not limited herein. For example, when UCI compression is performed by using HARQ-ACK bundling, HARQ-ACK bundling may be performed first, and then PUCCH resource selection may be performed.

In the embodiment of the present application, PUCCH resources for transmitting UCI compression information are indicated by a network side device. Optionally, the terminal may receive Radio Resource Control (RRC) signaling from the network side device, where the RRC signaling is used to indicate 1 or more PUCCH resources configured for transmitting UCI compression information in 1 or more PUCCH Resource sets (Resource sets).

Optionally, the terminal may receive a PRI from the network side device, and select a first PUCCH resource for transmitting UCI compression information from a configured PUCCH resource set according to the PRI. After that, the terminal may transmit UCI compression information according to the first PUCCH resource. It should be noted that, for the selection of the first PUCCH resource, the UCI compressed information may be obtained before compression, or the UCI compressed information may be obtained before compression.

Optionally, the selecting, according to the PRI, a first PUCCH resource for transmitting UCI compression information from the configured PUCCH resource set may include: firstly, the terminal judges whether the current PUCCH resource set of the terminal comprises PUCCH resources suitable for transmitting UCI compressed information or not according to the bit number of the UCI compressed information; then, when the current PUCCH resource set comprises PUCCH resources suitable for transmitting UCI compression information, the terminal selects a first PUCCH resource from the current PUCCH resource set; or, when the current PUCCH resource set does not comprise PUCCH resources suitable for transmitting UCI compression information, the terminal selects a new PUCCH resource set, and when the new PUCCH resource set comprises PUCCH resources suitable for transmitting UCI compression information, the terminal selects a first PUCCH resource from the new PUCCH resource set. The PUCCH resource suitable for transmitting UCI compressed information may be a PUCCH resource that can be used for transmitting UCI compressed information, or may be a PUCCH resource that can be used for transmitting UCI compressed information and has transmission performance that meets a preset condition, where the preset condition may be set based on an actual situation.

Optionally, when the current PUCCH resource set does not include a PUCCH resource suitable for transmitting UCI compression information, the terminal may further compress the UCI compression information into information of a preset bit, and transmit the information of the preset bit using a default PUCCH resource. For example, the information of the preset bit may be 1bit information such as 0 or 1.

That is, if there is no suitable PUCCH resource or PUCCH format in the current PUCCH resource set due to the number of bits of UCI compressed information, the terminal may replace the PUCCH resource set and select a resource that can transmit UCI compressed information from the new PUCCH resource set by using the PRI; or, the terminal may directly compress the UCI compression information to 1bit and transmit using a default resource.

The present application is described in detail below with reference to the following figures and specific examples.

Example 1

In this embodiment 1, in the PUCCH-Resource indicated by the PRI, a lower maxCodeRate threshold is configured by the higher layer as the threshold. When the code rate of the UCI to be transmitted is higher than the configured threshold, the terminal can choose to discard part of the CSI part information, so that the code rate is lower than the configured maxCodeRate threshold, and the compressed UCI transmission is realized.

As shown in fig. 3, the number of bits of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 3, due to the limitation of a preconfigured maxCodeRate threshold, that is, q1 is higher than the maxCodeRate threshold, the UE may discard part of CSI part information to obtain UCI compression information, as shown in fig. 3, the number of bits of the UCI compression information is n2, the code rate is q2, and q2 is lower than the maxCodeRate threshold, and transmit the UCI compression information on the PUCCH resource indicated by the PRI.

Example 2

In this embodiment 2, in the PUCCH-Resource indicated by the PRI, a lower maxCodeRate threshold is configured by the higher layer as the threshold. When the code of the UCI to be transmitted is higher than the configured threshold and a HARQ-ACK Bundling factor (Bundling factor) is configured in the PUCCH-Resource, such as the Bundling size, the terminal may select to transmit HARQ-ACK Bundling according to the Bundling size.

As shown in fig. 4, the bit number of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 4, due to the limitation of a preconfigured maxCodeRate threshold, that is, q1 is higher than the maxCodeRate threshold, the UE may perform HACK-ACK bundling according to the bundling size to obtain UCI compression information, as shown in fig. 4, the bit number of the UCI compression information is n2, the code rate is q2, and q2 is lower than the maxCodeRate threshold, and the UCI compression information is transmitted on the PUCCH resource indicated by the PRI, thereby implementing transmission of HARQ-ACK bundling.

Example 3

In this embodiment 3, in the PUCCH-Resource indicated by the PRI, a lower maxCodeRate threshold is configured by the higher layer as the threshold. When the code of the UCI to be transmitted is higher than the configured threshold and the transmission process selects the HARQ-ACK bundling form, the terminal may select a suitable value to perform HARQ-ACK bundling according to a value in a bit value set (Factor value set) configured in the PUCCH resource by a high layer, and the selected value needs to ensure that the code rate of information after bundling is less than the maxCodeRate threshold.

As shown in fig. 5, the number of bits of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 5, due to the limitation of a preconfigured maxCodeRate threshold, that is, q1 is higher than the maxCodeRate threshold, the UE may select an appropriate bundling size according to a Factor value set, and perform HACK-ACK bundling according to the selected bundling size to obtain UCI compression information, as shown in fig. 5, the number of bits of the UCI compression information is n2, the code rate is q2, and q2 is lower than the maxCodeRate threshold, and the UCI compression information is transmitted on the PUCCH resource indicated by the PRI, thereby implementing transmission of HARQ-ACK bundling.

Example 4

In this embodiment 4, in the PUCCH-Resource indicated by the PRI, a lower maxCodeRate threshold is configured by the higher layer as the threshold. When the code of UCI to be transmitted is higher than the configured threshold and the transmission process configures the HARQ-ACK feedback form based on the CBG through the parameter PDSCH-CodeBlockGroupTransition, the terminal only feeds back the HARQ-ACK information based on the TB, the feedback based on the CBG is not performed any more, and the code rate of the HARQ-ACK information based on the TB feedback is ensured to be smaller than the maxCodeRate threshold.

As shown in fig. 6, the number of bits of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 6, due to the limitation of the preconfigured maxCodeRate threshold, that is, q1 is higher than the maxCodeRate threshold, the UE will discard the CBG-based HARQ-ACK feedback information and synthesize TB-based HARQ-ACK feedback information, so that the number of bits of UCI compression information is n2, the code rate is q2, and q2 is lower than the maxCodeRate threshold.

Example 5

In this embodiment 5, in the PUCCH-Resource indicated by the PRI, a single-bit maxbitnum threshold is configured by the higher layer as the threshold. When the bit number of the UCI to be transmitted is greater than the configured threshold, the terminal may choose to discard the CSI portion information, so that the bit number transmitted by the terminal is less than the configured maxbitnum threshold, thereby implementing compressed UCI transmission.

As shown in fig. 7, the bit number of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates to transmit in the PUCCH resource shown in fig. 7, due to the limitation of the preconfigured maxbitnum threshold, that is, n1 is greater than the maxbitnum threshold, the UE may discard the CSI part information to obtain UCI compression information, as shown in fig. 7, the bit number of the UCI compression information is n2, the code rate is q2, and n2 is less than the maxbitnum threshold, and transmit the UCI compression information on the PUCCH resource indicated by the PRI.

Example 6

In this embodiment 6, in the PUCCH-Resource indicated by the PRI, a single-bit maxbitnum threshold is configured by the higher layer as the threshold. When the bit number of the UCI to be transmitted is higher than the configured threshold and a HARQ-ACK Bundling factor (Bundling factor) is configured in the PUCCH-Resource, such as a Bundling size, the terminal may select to perform HARQ-ACK Bundling transmission according to the Bundling size.

As shown in fig. 8, the bit number of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 8, due to the limitation of a preconfigured maxCodeRate threshold, that is, n1 is greater than the maxbitsmum threshold, the UE may perform HACK-ACK bundling according to the bundling size to obtain UCI compression information, as shown in fig. 8, the bit number of the UCI compression information is n2, the code rate is q2, and n2 is less than the maxbitsmum threshold, and the UCI compression information is transmitted on the PUCCH resource indicated by the PRI.

Example 7

In this embodiment 7, in the PUCCH-Resource indicated by the PRI, a single-bit maxbitnum threshold is configured by the higher layer as the threshold. When the bit number of the UCI to be transmitted is higher than the configured threshold and the transmission process selects the HARQ-ACK bundling form, the terminal may determine the bundling size by using ceil (N1/N), where N1 is an initial bit to be transmitted by the terminal, and N is a value of the maxbitnum threshold.

As shown in fig. 9, the bit number of UCI to be initially transmitted by the UE is N1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 9, due to the limitation of a preconfigured maxbitnum threshold, that is, N1 is greater than the maxbitnum threshold, the UE may determine a bundling size by using ceil (N1/N), and perform HACK-ACK bundling according to the bundling size to obtain UCI compression information, as shown in fig. 9, the bit number of the UCI compression information is N2, the code rate is q2, and N2 is less than the maxbitnum threshold, and the UCI compression information is transmitted on the PUCCH resource indicated by the PRI, thereby implementing transmission of HARQ-ACK bundling.

Example 8

In this embodiment 8, in the PUCCH-Resource indicated by the PRI, a single-bit maxbitnum threshold is configured by the higher layer as the threshold. When the bit number of the UCI to be transmitted is higher than the configured threshold and the transmission mode is the HARQ-ACK bundling, the terminal may select an appropriate value according to a value in a bit number set (Factor value set) configured in the PUCCH resource by the high layer to perform HARQ-ACK bundling, and the selected value needs to ensure that the bit number of information after bundling is less than the maxbitnum threshold.

As shown in fig. 10, the bit number of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates that the UE transmits in the PUCCH resource shown in fig. 10, due to the limitation of a preconfigured maxbitnum threshold, that is, n1 is greater than the maxbitnum threshold, the UE may select an appropriate bundling size according to the Factor value set, and perform HACK-ACK bundling according to the selected bundling size to obtain UCI compression information, as shown in fig. 10, the bit number of the UCI compression information is n2, the code rate is q2, and n2 is less than the maxbitnum threshold, and the UCI compression information is transmitted on the PUCCH resource indicated by the PRI, thereby implementing HARQ-ACK bundling transmission.

Example 9

In this embodiment 9, in the PUCCH-Resource indicated by the PRI, a single-bit maxbitnum threshold is configured by the higher layer as the threshold. When the bit number of UCI to be transmitted is higher than the configured threshold and a HARQ-ACK feedback form based on the CBG is configured through a parameter PDSCH-CodeBlockGroupTranssmision in the transmission process, the terminal only feeds back the HARQ-ACK information based on the TB, the feedback based on the CBG is not performed, and the bit number of the HARQ-ACK information based on the TB feedback is ensured to be smaller than the MaxBitsnum threshold.

As shown in fig. 11, the bit number of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 11, due to the limitation of the preconfigured maxbitnum threshold, that is, n1 is greater than the maxbitnum threshold, the UE discards the HARQ-ACK feedback information based on CBG and synthesizes the HARQ-ACK feedback information based on TB, so that the bit number of the compressed information is n2, the code rate is q2, and n2 is less than the maxbitnum threshold.

Example 10

In this embodiment 10, when the PUCCH-Format indicated by the PRI only includes Format0 or Format1, and the bit number of the UCI to be transmitted is higher than 2bits, at this time, if all CSI information is obtained after removing 2bits of HARQ-ACK or SR, the terminal may select to discard CSI part information, so that the bit number of transmission of the CSI part meets the requirement, and implement compressed UCI transmission.

As shown in fig. 12, the bit number of UCI to be initially transmitted by the UE is n1, and the code rate is q1, when the PRI indicates transmission in the PUCCH resource shown in fig. 12, due to the limitation of PUCCH-Format, the UE will discard all CSI part information, so that the bit number of compressed information is n2, the code rate is q2, and n2 is smaller than the maxbitnum threshold.

Example 11

In this embodiment 11, when the PUCCH-Format indicated by the PRI only includes Format0 or Format1, and the bit number of the UCI to be transmitted is higher than 2bits, at this time, if the size of the HARQ-ACK Bundling is configured in the PUCCH Resource, and the size can ensure that the bit to be transmitted is lower than 2bits, the terminal may perform HARQ-ACK Bundling transmission according to the size of the Bundling, so that the bit number of the transmission meets the requirement, and compressed UCI transmission is implemented.

As shown in fig. 13, the bit number of UCI to be initially transmitted by the UE is n1, the code rate is q1, when the PRI indicates that only the format0 or the format1 is used for transmission, and when the UE transmits in the PUCCH resource shown in fig. 13, the UE may perform HACK-ACK bundling according to the bundling size to obtain UCI compression information, as shown in fig. 13, the bit number of the UCI compression information is n2, the code rate is q2, and n2 is smaller than the preconfigured maxbitsunum threshold, and transmit the UCI compression information on the PUCCH resource indicated by the PRI, thereby implementing HARQ-ACK bundling transmission.

Example 12

In this embodiment 12, when the PUCCH-Format indicated by the PRI only includes Format0 or Format1, and the bit number of UCI to be transmitted is higher than 2bits, at this time, if a Factor value set size set is configured in the PUCCH Resource, a bundling size that can ensure that the bit number to be transmitted is lower than 2bits is provided, and the transmission mode is the HARQ-ACK bundling form, the terminal may select an appropriate value according to the value in the Factor value set to perform HARQ-ACK bundling, and the selected value needs to ensure that the code rate of information after bundling is lower than a maxCodeRate threshold.

As shown in fig. 14, the bit number of UCI to be initially transmitted by the UE is n1, the code rate is q1, when the PRI indicates that only format0 or format1 is used for transmission, and the UE transmits in the PUCCH resource shown in fig. 14, the UE may select an appropriate bundling size according to the Factor value set, and perform HACK-ACK bundling according to the selected bundling size to obtain UCI compression information, as shown in fig. 14, the bit number of the UCI compression information is n2, the code rate is q2, and q2 is lower than a preconfigured maxCodeRate threshold, and the UCI compression information is transmitted on the PUCCH resource indicated by the PRI, thereby implementing HARQ-ACK bundling transmission.

Example 13

In this embodiment 13, when the PUCCH-Format indicated by the PRI only includes Format0 or Format1, and the bit number of the UCI to be transmitted is higher than 2bits, if the transmission process configures a form of HARQ-ACK feedback based on a CBG and the CBG is a CBG that does not exceed 2 TBs, the UE only feeds back the HARQ-ACK based on the TB, does not perform feedback based on the CBG any more, and ensures that the HARQ-ACK code rate based on the TB feedback is lower than a preconfigured maxCodeRate threshold.

As shown in fig. 15, when the bit number of UCI initially to be transmitted by the UE is n1 and the code rate is q1, when the PRI indicates transmission only with format0 or format1 and transmission is in the PUCCH resource shown in fig. 15, the UE will discard the CBG-based HARQ-ACK feedback information and synthesize TB-based HARQ-ACK feedback information, such that the bit number of the compressed information is n2, the code rate is q2, and q2 is lower than the preconfigured maxCodeRate threshold.

Example 14

In this embodiment 14, as shown in fig. 16, if the UCI bit number n2 indicated by DAI in the UL grant is smaller than the HARQ-ACK bit number n1 that needs to be multiplexed on the PUSCH, that is, n1 > n2, the terminal needs to perform UCI compression transmission, and may discard part of CSI information, so that the transmitted bit number reaches the bit number requirement indicated by DAI, for example, the obtained UCI compression information of n 2bits, so as to be multiplexed on the PUSCH for transmission.

Example 15

In this embodiment 15, as shown in fig. 17, if the number of bits n2 indicated by DAI in the UL grant is smaller than the number of HARQ-ACK bits n1 that need to be multiplexed on PUSCH, the terminal needs to perform UCI compression transmission. At this time, if the size of the HARQ-ACK bundling is configured in the PUCCH Resource indicated by the PRI, the terminal may perform HARQ-ACK bundling transmission according to the size, so that the bit number of the transmission reaches the bit number requirement indicated by the DAI, for example, the obtained UCI compression information of n 2bits is multiplexed and transmitted on the PUSCH, and the compressed UCI transmission is realized.

Example 16

In this embodiment 16, as shown in fig. 18, if the UCI bit number n2 indicated by the DAI in the UL grant is smaller than the HARQ-ACK bit number n1 that needs to be multiplexed on the PUSCH, the terminal needs to perform UCI compression transmission. At this time, if a Factor value set is configured in the PUCCH Resource indicated by the PRI, and the transmission mode is in the form of HARQ-ACK bundling, the terminal may select an appropriate value to perform HARQ-ACK bundling according to the value in the Factor value set, so that the bit number transmitted by the terminal reaches the bit number requirement indicated by the DAI, for example, the obtained UCI compression information of n 2bits is multiplexed and transmitted on the PUSCH, and compressed UCI transmission is implemented.

Example 17

In this embodiment 17, as shown in fig. 19, if the UCI bit number n2 indicated by DAI in the UL grant is smaller than the HARQ-ACK bit number n1 that needs to be multiplexed on the PUSCH, the terminal needs to perform compressed transmission of UCI. At this time, if the transmission process is configured with a CBG-based HARQ-ACK feedback form, the terminal only feeds back the TB-based HARQ-ACK, and does not perform CBG-based feedback, so that the bit number transmitted by the terminal reaches the bit number requirement indicated by the DAI, for example, the obtained UCI compression information of n 2bits is multiplexed and transmitted on the PUSCH, and the compressed UCI transmission is realized.

Example 18

In this embodiment 18, if the UE first performs HARQ-ACK bundling and then performs PUCCH resource set selection, in a new resource set, the PUCCH resource selected by the UE is still the resource indicated by the PRI. As shown in fig. 20, if the total transmission bit number before compression is N1, the first X-1 bits can be reserved by introducing a minimum compressed bit number X, and the last N1-X +1 bits after bundle is 1bit, so that it can be transmitted with the current resource.

Example 19

In this embodiment 19, if the UE performs HARQ-ACK bundling first and then performs PUCCH resource set selection, in the new resource set, the PUCCH resource selected by the UE is still the resource indicated by the PRI. As shown in fig. 21, if the total transmission bit number before compression is N1, the compression scheme may not be changed, the compressed bit number is Y, and Y < X, then X-Y bits are padded after Y bits, and the value of X-Y bits is set to 0 or 1, so that it can be transmitted with the current resource.
