Description

Information determining method, information indicating method, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information determining method, an information indicating method, a terminal, and a network side device.

Background

In high reliability and low latency communications (Ultra-reliable and Low Latency Communications, URLLC), higher priority uplink transmissions are always guaranteed preferentially, while lower priority uplink transmissions are discarded when there is time domain overlap of transmission resources.

In order to guarantee the performance of lower priority uplink transmission, especially the transmission performance of hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat reQuest-ACK, HARQ-ACK) with highest importance in uplink control information (Uplink Control Information, UCI), consideration needs to be given to cross-priority uplink transmission multiplexing, for example, consideration needs to be given to multiplexing HARQ-ACKs corresponding to different priorities on a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

When considering multiplexing HARQ-ACKs on PUSCH across priorities, the following scenario may be considered:

the HARQ-ACK of priority i needs to be multiplexed on PUSCH of priority j (i/j takes on the value 0 or 1, i is not equal to j), and the following two cases can be further distinguished:

case 1: the PUSCH of priority j requires multiplexing HARQ-ACKs of priority j;

case 2: the PUSCH of priority j does not need to multiplex HARQ-ACKs of priority j;

for the above scenario, uplink-downlink allocation index (Uplink-Downlink Assignment Index, UL-DAI) indicated in Uplink-downlink control information (Uplink-Downlink Control Information, UL-DCI) of PUSCH transmission is scheduled, and is applicable to HARQ-ACK multiplexing transmission with the same priority, when HARQ-ACKs with different priorities need to be multiplexed on PUSCH for transmission, because there is no reference UL-DAI, transmission reliability cannot be guaranteed, and the reliability of PUSCH transmission where PUSCH transmission is located may be affected by rate matching, and in addition, the reliability of HARQ-ACK transmission may also have a larger influence on downlink data transmission performance.

In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is provided.

1. HARQ-ACK dynamic Codebook (Codebook).

When the UE organizes the HARQ-ACK bit sequence that needs to be reported at a certain feedback moment, based on a predefined rule and the scheduling situation of PDSCH transmissions on the single/multiple carriers that need to be reported at the feedback moment, the correspondence between each PDSCH transmission and a certain bit/bits in the organized HARQ-ACK bit sequence is determined, and this operation is called constructing the HARQ-ACK Codebook. When the release of the Semi-persistent scheduling (Semi-persistent Scheduling, SPS) PDSCH is indicated by downlink control information (Downlink Control Information, DCI), the UE is also required to acknowledge its reception using the HARQ-ACK bit to ensure that the understanding of whether the SPS PDSCH is in an active state remains consistent on both sides.

Alternatively, two HARQ-ACK Codebook schemes may be employed in a wireless communication system: the semi-static codebook (Type-1) and the dynamic codebook (Type-2), the former is used for feeding back all possible DCI indications and PDSCH transmissions, and is mainly used for guaranteeing the transmission reliability, the feedback cost is large, the latter is used for feeding back only the actual DCI indications and PDSCH transmissions, the feedback cost is small, and the transmission reliability can be affected to a certain extent when DCI missing detection conditions are common.

The dynamic codebook reserves HARQ-ACK feedback bits for each actually used DAI value by means of DAI counting the actually scheduled PDSCH transmission/SPS PDSCH release indication, if the UE speculates that some PDSCH allocation indications corresponding to DAIs or SPS PDSCH release indications are not received through other detected DAIs, the corresponding feedback bits are set as NACK, otherwise, the corresponding HARQ-ACK feedback bits are set according to the decoding result of the PDSCH transmission corresponding to each PDSCH allocation indication, and the corresponding feedback bits are set as ACK for the detected SPS PDSCH release indication.

DAIs are indicated by adopting a limited bit number (currently, a single DAI generally occupies 2 bits), and in order to expand the indication range, a modulo operation is introduced, namely, firstly counting sequentially from 1, and then modulo to obtain a DAI value corresponding to a certain count value.

When the UE configures only a single serving cell, the foregoing DAI counts one by one for only a single carrier according to the time sequence indicated by the DCI, which may be referred to as a counter DAI (simply referred to as a C-DAI). When the UE configures a plurality of serving cells, in order to further increase reliability, a Total DAI (abbreviated as T-DAI) is newly introduced for indicating the number of all DCI indications received up to the current time domain detection position, including all DCI indications received on each serving cell by the current time domain detection position, so that the value of the T-DAI is updated only when the time domain detection position changes. The T-DAI and the C-DAI are combined, so that the situation that the UE and the gNB are inconsistent in understanding of the transmission of the DCI indication when the DCI indication is lost on one or some of the service cells (as long as the DCI indications on all the service cells are not lost) at one time domain detection position can be effectively avoided.

HARQ-ACK Codebook is typically transmitted on PUCCH, and time and frequency domain information of PUCCH is indicated in DCI (with one exception: HARQ-ACK feedback of SPS PDSCH frequency domain information of PUCCH may be configured by higher layers). When a PUCCH transmission overlaps with a certain PUSCH transmission in the time domain, some or all UCI carried on the PUCCH will be multiplexed to the PUSCH transmission. For HARQ-ACK dynamic codebooks, because DCI omission affects the construction of HARQ-ACK codebooks, including the number of HARQ-ACK bits contained in the Codebook, which affects the time-frequency resources it occupies when multiplexing transmissions on PUSCH, and thus affects the time-frequency demapping and decoding of other data transmissions (e.g., UL-SCH) on PUSCH. In order to avoid the influence caused by the inconsistent understanding of the HARQ-ACK bit number at the UE and the network side, the DAI corresponding to the HARQ-ACK Codebook for multiplexing transmission may be indicated in the DCI format 0_1 for scheduling PUSCH, which may be referred to as UL DAI. The UL DAI is mainly used for determining the number of HARQ-ACK bits of the HARQ-ACK Codebook by the UE, and may be used for determining the missing detection condition of DCI corresponding to the HARQ-ACK bits at the tail of the HARQ-ACK Codebook. When HARQ-ACK Codebook involves only HARQ-ACK feedback of Transport Block (TB) granularity (i.e., two sub-codebooks are not involved), only a single UL DAI (indicated by DCI domain "1st downlink assignment index") is indicated in DCI format 0_1, corresponding to a single HARQ-ACK Codebook, and when HARQ-ACK Codebook involves both HARQ-ACK feedback of TB granularity and HARQ-ACK feedback of Code Block Group (CBG) granularity (i.e., two sub-codebooks are concatenated in sequence), two UL DAIs are indicated simultaneously in DCI format 0_1, with the first UL DAI (indicated by DCI domain "1st downlink assignment index") being applied to the first sub-Codebook and the second UL DAI (indicated by DCI domain "2nd downlink assignment index") being applied to the second sub-Codebook.

2. The uplink UE of the URLLC operates with priority (multiplexing) or multiplexing.

In the URLLC scenario, for the enhancements of UCI, two levels of priority (2-level priority) for HARQ-ACK are introduced. When the DCI format 0_1/0_2 schedules the PUSCH, a priority index (priority index) corresponding to the scheduled PUSCH transmission may be indicated by a priority indication (priority indicator) field in the DCI, and the value is 0 or 1. When the DCI format 1_1/1_2 schedules the PDSCH, the corresponding HARQ-ACK feedback and the priority index (0 or 1) corresponding to the PUCCH transmission carrying the feedback may be indicated by the priority indicator field in the DCI. When a certain PUSCH/PUCCH transmission does not indicate its corresponding priority index, default priority index 0 is adopted. And performing overlapped (overlapping) PUSCH/PUCCH related processing only when the corresponding priorities are the same, otherwise discarding the transmission corresponding to the priority index 0 and transmitting only the transmission corresponding to the priority index1 if the PUSCH/PUSCH transmissions of different priorities are overlapped (overlapping). The UCI is the same as the priority assumption of PUCCH/PUSCH carrying this UCI. The priority index 0 may be understood as a lower priority, and the priority index1 may be understood as a higher priority. When time-domain overlap occurs, the priority of the uplink transmission corresponding to the priority index1 is higher than that of the uplink transmission corresponding to the priority index 0.

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

As shown in fig. 2, an embodiment of the present application provides an information determining method, which is performed by a terminal, and includes:

step 201: and receiving first Downlink Control Information (DCI) for scheduling a first Physical Uplink Shared Channel (PUSCH), wherein the first DCI comprises a first Downlink Allocation Index (DAI), and the first PUSCH corresponds to a first priority.

The first DCI may be uplink DCI (UL-DCI).

Step 202: according to a first DAI, determining a DAI of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) application, wherein the first HARQ-ACK comprises HARQ-ACK with a second priority, and the second priority is different from the first priority.

Wherein the first HARQ-ACK is a HARQ-ACK that needs to multiplex transmission on the first PUSCH.

Here, the DAI of the first HARQ-ACK application includes the DAI of the first priority HARQ-ACK application and the DAI of the second priority HARQ-ACK application, or includes only the DAI of the second priority HARQ-ACK application. The DAI applied to the HARQ-ACK may be understood as a DAI used in a process or operation of generating the HARQ-ACK bit sequence corresponding to the HARQ-ACK, and may be used to determine the number of HARQ-ACK bits included in the corresponding HARQ-ACK bit sequence.

Step 203: and generating an HARQ-ACK bit sequence corresponding to the first HARQ-ACK according to the determined DAI.

And under the condition that the HARQ-ACK of the second priority needs to be multiplexed on the PUSCH of the first priority, generating a corresponding HARQ-ACK bit sequence according to the DAI of the HARQ-ACK application of the second priority determined by the first DAI. The HARQ-ACK bit sequence corresponding to the first HARQ-ACK may be a HARQ-ACK bit sequence corresponding to only the HARQ-ACK of the second priority, or may be a HARQ-ACK bit sequence corresponding to the HARQ-ACK of the first priority at the same time, or a HARQ-ACK bit sequence corresponding to the HARQ-ACK of the second priority, which is not limited herein.

According to the information determining method, first DCI for scheduling a first PUSCH is received, the first DCI comprises a first DAI, and the first PUSCH corresponds to a first priority; according to the first DAI, determining the DAI applied by the first HARQ-ACK which needs to be multiplexed on the first PUSCH, wherein the first HARQ-ACK comprises the HARQ-ACK with the second priority, so that when the HARQ-ACK with the second priority is multiplexed on the PUSCH with the first priority for transmission, a HARQ-ACK bit sequence corresponding to the first HARQ-ACK can be generated according to the determined DAI, and further, the reliability of the HARQ-ACK multiplexing transmission is improved.

As a first alternative implementation manner, the determining, according to the first DAI, the DAI of the first hybrid automatic repeat request acknowledgement HARQ-ACK application includes:

and taking the first DAI as the DAI of the HARQ-ACK application of the second priority.

In this implementation, optionally, the UE does not want to multiplex HARQ-ACKs corresponding to two priorities on the same PUSCH at the same time, i.e. only HARQ-ACKs of one priority different from the priority of PUSCH are multiplexed on PUSCH, such as only HARQ-ACKs of the second priority are multiplexed on PUSCH. The specific implementation can be ensured by the base station scheduling.

Optionally, when the value of the first DAI is 4 and the UE does not detect any downlink DCI or SPS PDSCH requiring multiplexing of the corresponding HARQ-ACK on the PUSCH, the UE does not multiplex the HARQ-ACK on the PUSCH.

Optionally, when the UE detects that the HARQ-ACK corresponding to a certain priority needs to be multiplexed on the PUSCH, the UE applies the first DAI to the HARQ-ACK corresponding to the detected priority.

As a second alternative implementation, the first DAI comprises a first set of DAIs and a second set of DAIs;

the determining the DAI of the first hybrid automatic repeat request acknowledgement (HARQ-ACK) application according to the first DAI comprises the following steps:

and taking the second group of DAIs as DAIs applied by the HARQ-ACK of the second priority.

Optionally, after receiving the first downlink control information DCI for scheduling the first physical uplink shared channel PUSCH, the method further includes: and taking the first group of DAIs as DAIs applied by the HARQ-ACK of the first priority.

It should be noted that, in the embodiment of the present application, when only the HARQ-ACK feedback of the TB (Transport Block) granularity is involved (i.e., the HARQ-ACK to be multiplexed only includes the HARQ-ACK for the TB-level downlink allocation feedback), a group of DAIs corresponds to a single UL DAI; when both HARQ-ACK feedback with TB granularity and HARQ-ACK feedback with CBG (Code Block Group) granularity are involved (i.e. the HARQ-ACK to be multiplexed includes both HARQ-ACK for TB-level downlink allocation feedback and HARQ-ACK for CBG-level downlink allocation feedback, where CBG-level downlink allocation may be understood as corresponding to two UL is when a target downlink carrier scheduled by a higher layer for DCI is configured to turn on CBG-based retransmission, PDSCH transmission indicated by non-fallback downlink DCI, at this time, each possible corresponding CBG based on PDSCH transmission is fed back to the corresponding HARQ-ACK, the HARQ-ACK to be multiplexed corresponds to two HARQ-ACK sub-codebooks, where the first sub-codebook corresponds to the HARQ-ACK feedback with TB granularity and the second sub-codebook corresponds to the HARQ-ACK feedback with CBG granularity, where the first UL is corresponding to the first sub-codebook and the second sub-codebook corresponds to the second dacodebook.

Optionally, the first set of DAIs corresponds to priority index 0, or is of a lower priority, that is, the first set of DAIs is used as the DAI of the HARQ-ACK application corresponding to priority index 0; the second set of DAIs corresponds to priority index 1, or higher priority, i.e., the second set of DAIs is used as the DAI for the HARQ-ACK application corresponding to priority index 1.

Optionally, the first set of DAIs corresponds to a priority corresponding to PUSCH scheduling, and the second set of DAIs corresponds to another priority different from PUSCH scheduling.

Alternatively, whether the second set of DAIs is included in the first DAI may be determined based on protocol specifications or higher-level configurations.

Optionally, for the dynamic codebook or the enhanced dynamic codebook, when the DAI corresponding to a certain priority is given a value of 4, and the HARQ-ACK corresponding to the priority is not detected (for example, DL DCI requiring feedback of the HARQ-ACK in the slot/sub-slot where the PUSCH transmission is located is not detected, and/or SPS PDSCH requiring feedback of the HARQ-ACK in the slot/sub-slot where the PUSCH transmission is located) to be transmitted, the HARQ-ACK corresponding to the priority is not multiplexed on the PUSCH transmission scheduled by the UL DCI.

Alternatively, for a semi-static codebook, when the DAI value corresponding to a certain priority is 0, the HARQ-ACK corresponding to the priority is not multiplexed on the PUSCH transmission scheduled by the UL DCI (unless the specific codebook is specified by the protocol).

As a third alternative implementation manner, the determining, according to the first DAI, the DAI of the first hybrid automatic repeat request acknowledgement HARQ-ACK application includes:

taking the first DAI as the DAI of the HARQ-ACK application of the first target priority;

determining DAI applied by the HARQ-ACK of the first other priority according to the detection condition of the downlink DCI corresponding to the HARQ-ACK of the first other priority;

wherein the first target priority is one of:

the first priority;

the higher of the first priority and the second priority;

the lower of the first priority and the second priority;

the first other priority refers to a priority other than the first target priority among the first priority and the second priority.

Here, the scheme corresponding to the third alternative implementation manner may be two parallel schemes corresponding to the scheme for determining the DAI of the first HARQ-ACK application in the step 202, that is, the scheme corresponding to the third alternative implementation manner may be implemented independently.

It is understood that when the first priority and the second priority correspond to priority index0 and 1, respectively, or to priority index 1 and 0, respectively, the higher priority of the first priority and the second priority corresponds to priority index 1, and the lower priority of the first priority and the second priority corresponds to priority index 0.

For example, the first DCI is determined by a field indication or by other rules, and its scheduled PUSCH transmission is prioritized by a first priority j. And taking the first DAI as the DAI of the HARQ-ACK application corresponding to the first priority, wherein the DAI of the HARQ-ACK application of the second priority can be determined based on the detection condition of the downlink DCI corresponding to the HARQ-ACK of the second priority.

For another example, if the first DAI is used as the DAI of the HARQ-ACK application corresponding to the higher priority or the lower priority, the DAI of the HARQ-ACK application of another priority may be determined based on the detection situation of the downlink DCI corresponding to the HARQ-ACK of the other priority.

As a fourth alternative implementation manner, the determining, according to the first DAI, the DAI of the first hybrid automatic repeat request acknowledgement HARQ-ACK application includes:

determining a second DAI according to the detection condition of the downlink DCI corresponding to the HARQ-ACK of the first priority;

determining a third DAI according to the detection condition of the downlink DCI corresponding to the HARQ-ACK of the second priority;

and in the case that the sum of the second DAI and the third DAI is equal to the value of the first DAI, taking the second DAI as the DAI of the HARQ-ACK application of the first priority and taking the third DAI as the DAI of the HARQ-ACK application of the second priority.

In this implementation manner, in an ideal case that no downlink DCI missed detection exists, the terminal expects or considers that the value of the first DAI is set based on the sum of the second DAI and the third DAI (may be the value obtained after the sum is modulo, for example, the sum of the second DAI and the third DAI is modulo 4, and the obtained value is set as the value of the first DAI). When the sum (taking into account modulo operation) of the second DAI and the third DAI is equal to the value of the first DAI, the terminal may determine that no missed detection exists in the downlink DCI corresponding to the first priority and the downlink DCI corresponding to the second priority, and accordingly, the terminal may use the second DAI as the DAI of the HARQ-ACK application of the first priority and use the third DAI as the DAI of the HARQ-ACK application of the second priority. When the sum (taking into account modulo operation) of the second DAI and the third DAI is not equal to the value of the first DAI, the terminal may determine that the downlink DCI corresponding to the first priority and/or the downlink DCI corresponding to the second priority is missed, and at this time, the terminal may determine the DAI a determined by detecting the downlink DCI corresponding to one of the priorities a (e.g., the higher priority) and the first DAI, and determine the DAI b applied by the HARQ-ACK of the other priority b. DAI a is applied to HARQ-ACKs of priority a.

Here, the DAIs of the HARQ-ACK applications with two priorities may be determined based on the detection conditions of the downlink DCI corresponding to each priority, respectively, and it is ensured that the sum of the DAIs of the HARQ-ACK applications with two priorities satisfies the value of the first DAI. For example, the terminal guarantees that the sum of the DAIs of the HARQ-ACK applications of the two priorities satisfies the above-mentioned value of the first DAI based on the corresponding operation described above.

As a fifth optional implementation manner, the determining, according to the first DAI, the DAI of the first hybrid automatic repeat request acknowledgement HARQ-ACK application includes:

determining the DAI of HARQ-ACK application of a first target priority according to the detection condition of downlink DCI corresponding to the first target priority;

determining DAIs of HARQ-ACK applications of first other priorities according to the DAIs of the HARQ-ACK applications of the first target priority and the first DAIs;

wherein the first target priority is one of:

the first priority;

the higher of the first priority and the second priority;

the lower of the first priority and the second priority;

the first other priority refers to a priority other than the first target priority among the first priority and the second priority, and a sum of a DAI of the HARQ-ACK application of the first priority and a DAI of the HARQ-ACK application of the second priority is equal to a value of the first DAI.

In this implementation manner, in an ideal case that there is no downlink DCI missed detection, the terminal expects or considers that the value of the first DAI is set based on the sum of the DAI of the HARQ-ACK application of the first target priority and the DAI of the HARQ-ACK application of the first other priority (may be the value obtained by modulo the sum, for example, the value obtained by modulo 4 the sum of the DAI of the HARQ-ACK application of the first target priority and the DAI of the HARQ-ACK application of the first other priority, and the obtained value is set to the value of the first DAI).

Since the DL DCI detection reliability of the higher priority is higher, it is preferable that the first target priority is the higher priority of the first priority and the second priority. Namely, firstly determining the DAI of the HARQ-ACK application with higher priority based on the detection condition of the DL DCI with higher priority, and then obtaining the DAI of the HARQ-ACK application with lower priority according to the value of the first DAI and the DAI of the HARQ-ACK application with higher priority.

Optionally, in the third optional implementation manner and the fifth optional implementation manner, the method further includes:

and carrying DAI information of the first other priorities in the first PUSCH. The DAI information can be decoded before the HARQ-ACK corresponding to the first other priority carried on the first PUSCH, and is used for indicating the bit number corresponding to the HARQ-ACK corresponding to the first other priority carried on the first PUSCH to a network side by a terminal, so as to inform the network side of the resource amount used for carrying the HARQ-ACK corresponding to the first other priority on the first PUSCH, assist the network side to decode other information carried on the first PUSCH, and improve PUSCH detection performance. A possible network side is implemented by the network side firstly extracting, after receiving the first PUSCH, a code bit sequence corresponding to the HARQ-ACK of the first target priority and/or the DAI information of the first other priority, and decoding the HARQ-ACK of the first target priority and/or the DAI information of the first other priority. Here, it may be assumed that a protocol specifies or configures, at a higher layer, a starting mapping position of a coded bit sequence corresponding to the HARQ-ACK of the first target priority and/or the DAI information of the first other priority in the first PUSCH transmission, where a network side group starts to map the position, a detection situation of downlink DCI corresponding to the first target priority, a DAI applied to the HARQ-ACK of the first target priority, a bit number of the DAI information, and other configuration parameters, etc., and may determine the HARQ-ACK bit number of the first target priority, and a coded bit sequence length and an ending mapping position corresponding to the HARQ-ACK of the first target priority and/or the DAI information of the first other priority. The network side can determine the number of HARQ-ACK bits of the first other priority based on the DAI information of the first other priority obtained by decoding and combining with the detection situation of the downlink DCI corresponding to the first other priority, so as to further determine the resource mapping situation of the HARQ-ACK of the first other priority on the first PUSCH, so that the network side can accurately know the mapping position and the mapping length of other information (except the HARQ-ACK of the first target priority and/or the DAI information of the first other priority and the information carried on the first PUSCH except the HARQ-ACK of the first other priority) carried on the first PUSCH, thereby ensuring the decoding performance of the other information carried on the first PUSCH.

Alternatively, the DAI information may correspond to a set of DAIs. When the first other priority HARQ-ACK involves only TB granularity HARQ-ACK feedback, this DAI information may correspond to a single UL DAI and may correspond to 2 bits; when both HARQ-ACK feedback of TB granularity and HARQ-ACK feedback of CBG granularity are involved, this DAI information may correspond to two UL DAIs, and may correspond to 4 bits, where a first UL DAI corresponds to a first sub-codebook, may correspond to the first 2 bits, and a second UL DAI corresponds to a second sub-codebook, may correspond to the last 2 bits.

Based on this, the information determining method of the embodiment of the present application further includes:

under the condition that the HARQ-ACK of the first target priority is actually multiplexed in the first PUSCH, sequentially cascading DAI information bits of the first other priorities carried in the first PUSCH with the HARQ-ACK bit sequence of the first target priority, and coding and mapping the bit sequence obtained by cascading;

or under the condition that the HARQ-ACK of the first target priority does not need to be multiplexed in the first PUSCH, encoding and mapping DAI information of first other priorities carried in the first PUSCH as the HARQ-ACK of the first target priority.

The DAI information bits of the first other priority and the HARQ-ACK bit sequence of the first target priority may be sequentially concatenated, and the concatenated bit sequence may be encoded and mapped. Alternatively, in the case of sequential concatenation, the DAI information bits of the first other priority may be placed before or after the HARQ-ACK bit sequence of the first target priority, or at a designated position specified by the protocol or by a higher layer configuration.

Here, the DAI information bits of the first other priority may be used as an input information bit sequence, and encoded and mapped onto the PUSCH using exactly the same processing parameters and processing procedures as the HARQ-ACK bit sequence of the first target priority.

The information determining method of the embodiment of the application further comprises the following steps:

and when the multiplexing process of the PUSCH transmission scheduled by the first DCI is executed, mapping the HARQ-ACK of the first target priority and/or the coding bit sequence corresponding to the DAI information of the first other priority is executed, and then mapping the coding bit sequence corresponding to the HARQ-ACK of the first other priority is executed.

As a sixth alternative implementation manner, the determining, according to the first DAI, the DAI of the first hybrid automatic repeat request acknowledgement HARQ-ACK application includes:

And respectively taking the first DAI as the DAI of the HARQ-ACK application of the first priority and the DAI of the HARQ-ACK application of the second priority.

Here, the first DAI is used as the DAI of the HARQ-ACK application of two priorities at the same time. Alternatively, the base station may schedule to ensure that the HARQ-ACKs with both priorities meet or match the first DAI, or the base station may not do so, but select an appropriate DAI value when indicating the first DAI, so as to ensure that the HARQ-ACKs with both priorities can be completely multiplexed, and possibly that the HARQ-ACKs with a certain priority have tail redundancy bits.

Optionally, when the multiplexing process of the PUSCH transmission scheduled by the first DCI is performed, mapping of the coded bit sequence of the HARQ-ACK of the first target priority is performed first, and then mapping of the coded bit sequence corresponding to the HARQ-ACK of the first other priority is performed. Here, the first target priority is a higher or lower priority among the first priority and the second priority, and the first other priority is a priority other than the first target priority among the first priority and the second priority.

According to the information determining method, first DCI for scheduling a first PUSCH is received, the first DCI comprises a first DAI, and the first PUSCH corresponds to a first priority; according to the first DAI, determining the DAI applied by the first HARQ-ACK which is required to be multiplexed on the first PUSCH, wherein the first HARQ-ACK comprises the HARQ-ACK with the second priority, so that when the HARQ-ACK with the second priority is multiplexed on the PUSCH with the first priority for transmission, a HARQ-ACK bit sequence corresponding to the first HARQ-ACK can be generated according to the determined DAI, thereby improving the reliability of the HARQ-ACK multiplexing transmission, and further improving the performance of the PUSCH transmission and the PDSCH transmission.

The third PUCCH time unit herein may be understood as a PUCCH time unit usable for HARQ-ACK feedback of the second target priority or as all PUCCH time units usable for HARQ-ACK feedback of the second target priority.

For example, when the second target priority corresponds to only the fourth priority, the third PUCCH time unit may be understood as all PUCCH time units available for HARQ-ACK feedback of the fourth priority; when the second target priority corresponds to both the third priority and the fourth priority, the third PUCCH time unit may be understood as all PUCCH time units available for HARQ-ACK feedback of the third priority and all PUCCH time units available for HARQ-ACK feedback of the fourth priority. The PUCCH time units usable by the HARQ-ACKs of the third priority and the fourth priority may be equal in length or different in length.

Alternatively, the PUCCH time unit may be a PUCCH slot (slot) or a PUCCH sub-slot (sub-slot).
