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 device.

Background

In high-reliability and Low-Latency Communications (URLLC), when transmission resources overlap in time domain, a higher priority uplink transmission is always preferentially guaranteed, while a lower priority uplink transmission is dropped.

In order to ensure the performance of lower priority Uplink transmission, especially the transmission performance of Hybrid Automatic Repeat reQuest acknowledgement (HARQ-ACK) with the highest importance in Uplink Control Information (UCI), Uplink transmission multiplexing across priorities needs to be considered, for example, multiplexing HARQ-ACKs corresponding to different priorities on a Physical Uplink Shared Channel (PUSCH) needs to be considered.

When considering cross-priority multiplexing of HARQ-ACKs on PUSCH, the following scenario may be considered:

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

case 1: the PUSCH of the priority j needs to multiplex the HARQ-ACK of the priority j;

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

for the above scenario, the Uplink-Downlink Assignment Index (UL-DAI) indicated in the Uplink-Downlink Control Information (UL-DCI) for scheduling PUSCH transmission is suitable for HARQ-ACK multiplexing transmission with the same priority, and when HARQ-ACKs with different priorities need to be multiplexed and transmitted on the PUSCH, because there is no reference UL-DAI, the transmission reliability cannot be guaranteed, the reliability of the PUSCH transmission where the HARQ-ACK is located may be affected by rate matching, and in addition, the reliability of HARQ-ACK transmission may also have a great impact on the 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 made.

1. HARQ-ACK dynamic Codebook (Codebook).

When the UE organizes the HARQ-ACK bit sequence that needs to be reported at a certain feedback time, based on a predefined rule and the scheduling condition of PDSCH transmission on a single/multiple carriers that need to report HARQ-ACK at the feedback time, determining the corresponding relationship between each PDSCH transmission and a certain/some bits in the organized HARQ-ACK bit sequence, which is called constructing HARQ-ACK Codebook. When the Downlink Control Information (DCI) indicates a Semi-persistent Scheduling (SPS) PDSCH release, the UE is also required to acknowledge its reception using the HARQ-ACK bit to ensure that the understanding of both sides on whether the SPS PDSCH is in an active state is consistent.

Optionally, two HARQ-ACK Codebook schemes may be employed in the wireless communication system: the semi-static codebook (Type-1) and the dynamic codebook (Type-2) are respectively used for feeding back all possible DCI (downlink control information) instructions and PDSCH (physical downlink shared channel) transmission and are mainly used for guaranteeing transmission reliability, the feedback overhead is large, the dynamic codebook (Type-2) only feeds back actual DCI instructions and PDSCH transmission, the feedback overhead is small, and the transmission reliability can be influenced to a certain extent when DCI missing detection conditions are common.

The dynamic codebook reserves HARQ-ACK feedback bits for each DAI value used actually through a mode of carrying out DAI counting on PDSCH transmission/SPS PDSCH release instructions scheduled actually, if UE presumes that PDSCH allocation instructions or SPS PDSCH release instructions corresponding to some DAIs are not received through other detected DAIs, the corresponding feedback bits are set to be NACK, otherwise, the corresponding HARQ-ACK feedback bits are set according to decoding results of PDSCH transmission corresponding to the PDSCH allocation instructions, and the corresponding feedback bits are set to be ACK for the detected SPS PDSCH release instructions.

The DAI is indicated by using a limited number of bits (currently, a single DAI generally occupies 2 bits), and in order to expand the indication range, a modulo operation is introduced, that is, the DAI is sequentially counted from 1 and then modulo is performed to obtain a DAI value corresponding to a certain count value.

When the UE only configures a single serving cell, the DAIs are counted one by one according to the time sequence indicated by the DCI only for a single carrier, which may be referred to as counter DAI (C-DAI for short). When the UE configures multiple serving cells, to further increase reliability, a Total DAI (referred to as T-DAI for short) is newly introduced to indicate the number of all DCI indications received up to the current time domain detection position, including all DCI indications received by the current time domain detection position on each serving cell, 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 used in combination, so that the condition that the transmission comprehension of the DCI by the UE and the gNB is inconsistent when the DCI indication on a certain serving cell or certain serving cells is lost (as long as the DCI indication on all the serving cells is not lost) at a certain time domain detection position can be effectively avoided.

HARQ-ACK Codebook is typically transmitted on PUCCH, whose time and frequency domain information is indicated in DCI (with one exception: the frequency domain information of the HARQ-ACK feedback PUCCH for SPS PDSCH may be configured by higher layers). When the PUCCH transmission and a PUSCH transmission are overlapped in time domain, part or all of UCI carried on the PUCCH is multiplexed to the PUSCH for transmission. For the HARQ-ACK Codebook, the missing detection of DCI may affect the construction of the HARQ-ACK Codebook, including the number of HARQ-ACK bits included in the Codebook, and the number of HARQ-ACK bits may affect the time-frequency resources occupied by multiplexing transmission on the PUSCH, thereby affecting the time-frequency demapping and decoding of other data transmission (e.g., UL-SCH) on the PUSCH. In order to avoid the influence caused by the inconsistency of the number of HARQ-ACK bits between the UE and the network, a DAI corresponding to the HARQ-ACK Codebook for the multiplexed transmission may be indicated in DCI format 0_1 for scheduling PUSCH, which may be referred to as an UL DAI. The UL DAI is mainly used for the UE to determine the HARQ-ACK bit number of the HARQ-ACK Codebook, and may be used to determine the missed detection condition of DCI corresponding to the HARQ-ACK Codebook tail HARQ-ACK bit. When HARQ-ACK Codebook only refers to HARQ-ACK feedback of Transport Block (TB) granularity (i.e. does not refer to two sub-codebooks), only a single UL DAI (indicated by DCI field "1 st downlink assignment index") is indicated in DCI format 0_1, corresponding to a single HARQ-ACK Codebook, when HARQ-ACK Codebook refers to HARQ-ACK feedback of TB granularity and HARQ-ACK feedback of Code Block Group (CBG) granularity (i.e. sequentially concatenated by two sub-codebooks), two UL DAIs are indicated simultaneously in DCI format 0_1, where the first UL DAI (indicated by DCI field "1 st downlink assignment index") is applied to the first sub-Codebook and the second UL DAI (indicated by DCI field "2 nd downlink assignment index") is applied to the second sub-Codebook.

2. And the uplink UE of the URLLC operates according to priority processing (prioritization) or multiplexing (multiplexing).

Under the URLLC scene, for the enhancement of UCI, two-level priority (2-level priority) aiming at HARQ-ACK is 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 indicator (priority indicator) field in the DCI, and is set to 0 or 1. When the DCI format 1_1/1_2 schedules the PDSCH, it may indicate the HARQ-ACK feedback corresponding to the DCI through the priority indicator field and the priority index (0 or 1) corresponding to the PUCCH transmission carrying the feedback. When a certain PUSCH/PUCCH transmission does not indicate the corresponding priority index, a default priority index0 is adopted. And only when the corresponding priorities are the same, performing overlapping (overlapping) PUSCH/PUCCH related processing, otherwise, if the PUSCH/PUSCH transmissions with different priorities are overlapped (overlapping), discarding the transmission corresponding to the priority index0, and only transmitting the transmission corresponding to the priority index 1. The priority of the UCI and the PUCCH/PUSCH carrying the UCI is assumed to be the same. Here, priority index0 may be understood as a lower priority, and priority index1 may be understood as a higher priority. When time domain overlapping occurs, the priority of the uplink transmission corresponding to the priority index1 is higher than the priority of the uplink transmission corresponding to the priority index 0.

The information determining 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.

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

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

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

Step 202: determining DAI of a first hybrid automatic repeat request acknowledgement (HARQ-ACK) application according to a first DAI, 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 which needs to be multiplexed for transmission on the first PUSCH.

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

Step 203: and generating a 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 applied by the HARQ-ACK 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 also be a HARQ-ACK bit sequence corresponding to the HARQ-ACK of the first priority and a HARQ-ACK bit sequence corresponding to the HARQ-ACK of the second priority, which is not limited herein.

The information determining method of the embodiment of the application receives first DCI used for scheduling a first PUSCH, wherein the first DCI comprises a first DAI, and the first PUSCH corresponds to a first priority; and determining the DAI applied by the first HARQ-ACK which needs to be multiplexed on the first PUSCH according to the first DAI, 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 and transmitted on the PUSCH with the first priority, the HARQ-ACK bit sequence corresponding to the first HARQ-ACK can be generated according to the determined DAI, and the reliability of the HARQ-ACK multiplexing transmission is further improved.

As a first optional implementation manner, the determining, according to the first DAI, a DAI of a 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 desire to multiplex HARQ-ACKs corresponding to two priorities on the same PUSCH at the same time, that is, only multiplexes HARQ-ACKs of one priority different from the priority of the PUSCH on the PUSCH, such as only multiplexing HARQ-ACKs of the second priority on the PUSCH. The specific implementation can be guaranteed by base station scheduling.

Optionally, the value of the first DAI is 4, and when the UE does not detect any downlink DCI or SPS PDSCH that needs to multiplex 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 detected HARQ-ACK corresponding to the priority.

As a second alternative implementation, the first DAI includes a first group of DAIs and a second group of DAIs;

the determining the DAI of the first HARQ-ACK application according to the first DAI includes:

and taking the second group of DAIs as DAIs of the HARQ-ACK application 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 of the HARQ-ACK application with the first priority.

It should be noted that, a group of DAIs in this embodiment of the present application corresponds to a single UL DAI when only HARQ-ACK feedback of TB (Transport Block) granularity is involved (that is, HARQ-ACK to be multiplexed only includes HARQ-ACK for TB level downlink allocation feedback); when HARQ-ACK feedback of TB granularity and HARQ-ACK feedback of CBG (Code Block Group) granularity are related at the same time (namely the HARQ-ACK needing multiplexing simultaneously comprises the HARQ-ACK fed back by aiming at TB-level downlink allocation and the HARQ-ACK fed back by aiming at CBG-level downlink allocation, the CBG-level downlink allocation can be understood as that when the high layer configures starting retransmission based on CBG for a target downlink carrier wave scheduled by DCI, PDSCH transmission indicated by non-fallback downlink DCI is carried out, and at the moment, corresponding HARQ-ACK is fed back by each possibly corresponding CBG based on PDSCH transmission, the HARQ-ACK needing multiplexing corresponds to two HARQ-ACK sub-codebooks UL-codebook, wherein the first HARQ-ACK feedback corresponds to TB granularity, and the second HARQ-ACK feedback corresponds to HARQ-ACK feedback of CBG granularity), two DAIs are corresponded, wherein the first UL DAI corresponds to a first sub-codebook and the second UL DAI corresponds to a second sub-codebook.

Optionally, the first group of DAIs corresponds to priority index0, or has a lower priority, that is, the first group of DAIs is used as a DAI for HARQ-ACK application corresponding to priority index 0; the second group of DAIs corresponds to priority index1, or a higher priority, that is, the second group of DAIs is used as the DAI for the HARQ-ACK application corresponding to the priority index 1.

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

Alternatively, whether the first DAI includes the second group of DAIs may be determined based on protocol specification or higher layer configuration.

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

Optionally, for the 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 a specific codebook condition is specified by a protocol).

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

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

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

wherein the first target priority is one of:

the first priority;

a higher priority of the first priority and the second priority;

a lower priority 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, in the scheme corresponding to the third optional implementation, the scheme for determining the DAI applied by the first HARQ-ACK corresponding to step 202 is two parallel schemes, that is, the scheme corresponding to the third optional implementation may be implemented independently.

It is to be understood that when the first priority and the second priority correspond to priority indexes 0 and 1, respectively, or priority indexes 1 and 0, respectively, a higher priority of the first priority and the second priority corresponds to priority index1, and a lower priority of the first priority and the second priority corresponds to priority index 0.

For example, the first DCI is indicated by a field or determined by other rules, and the priority of its scheduled PUSCH transmission is the first priority j. And taking the first DAI as the DAI applied by the HARQ-ACK corresponding to the first priority, wherein the DAI applied by the HARQ-ACK 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 for the HARQ-ACK application corresponding to the higher priority or the lower priority, the DAI for the HARQ-ACK application of another priority may be determined based on the detection condition of the downlink DCI corresponding to the HARQ-ACK of the another priority.

As a fourth optional implementation manner, the determining, according to the first DAI, a DAI of a 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 when the sum of the second DAI and the third DAI is equal to the value of the first DAI, using the second DAI as the DAI applied by the HARQ-ACK of the first priority, and using the third DAI as the DAI applied by the HARQ-ACK of the second priority.

In this implementation, in an ideal case where there is no missing detection of downlink DCI, 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 (which may be a value obtained after modulo the sum, for example, modulo the sum of the second DAI and the third DAI by 4, and sets the obtained value as the value of the first DAI). When the sum of the second DAI and the third DAI (considering modulo operation) is equal to the value of the first DAI, the terminal may determine that there is no missing detection 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 applied by the HARQ-ACK of the first priority and use the third DAI as the DAI applied by the HARQ-ACK of the second priority. When the sum (considering the 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 has a missed detection, and at this time, the terminal may determine, based on the downlink DCI corresponding to one priority a (for example, a higher priority), the DAI a determined by detecting the HARQ-ACK application of another priority b, and the first DAI. DAI a is applied to HARQ-ACK of priority a.

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

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

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

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

wherein the first target priority is one of:

the first priority;

a higher priority of the first priority and the second priority;

a lower priority of the first priority and the second priority;

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

In this implementation, under an ideal condition that there is no missing detection of downlink DCI, the terminal expects or considers that the value of the first DAI is set based on a 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 (which may be a value obtained after modulo the sum, for example, 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 sets the obtained value as the value of the first DAI).

Preferably, the first target priority is a higher priority of the first priority and the second priority, because the higher priority DL DCI detection reliability is higher. Namely, the DAI applied by the HARQ-ACK with higher priority is determined based on the detection condition of the DL DCI with higher priority, and then the DAI applied by the HARQ-ACK with lower priority is obtained according to the value of the first DAI and the DAI applied by the HARQ-ACK with higher priority.

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

carrying DAI information of the first other priority in the first PUSCH. This DAI information may be decoded before the HARQ-ACK corresponding to the first other priority carried on the first PUSCH, so that the terminal indicates, to the network side, the number of bits corresponding to the HARQ-ACK corresponding to the first other priority carried on the first PUSCH, thereby notifying the network side of the amount of resources used for carrying the HARQ-ACK corresponding to the first other priority on the first PUSCH, assisting the network side in decoding other information carried on the first PUSCH, and improving PUSCH detection performance. One possible implementation of the network side is that, after receiving the first PUSCH, the network side first extracts the coded bit sequence corresponding to the HARQ-ACK of the first target priority and/or the DAI information of the first other priority, and decodes the HARQ-ACK of the first target priority and/or the DAI information of the first other priority. It may be assumed here that a protocol specifies or a higher layer configures a starting mapping position of the 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 the network determines, based on the starting mapping position, a detection condition of the downlink DCI corresponding to the first target priority, the DAI applied to the HARQ-ACK of the first target priority, the number of bits of the DAI information, other configuration parameters, and the like, the number of bits of the HARQ-ACK of the first target priority, and the length of the coded bit sequence and the ending mapping position corresponding to the HARQ-ACK of the first target priority and/or the DAI information of the first other priority. Based on the decoded DAI information of the first other priority, the network side, in combination with the detection condition of the downlink DCI corresponding to the first other priority, can determine the number of HARQ-ACK bits of the first other priority, thereby further determining the resource mapping condition of the HARQ-ACK of the first other priority on the first PUSCH, so that the network side can exactly 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 HARQ-ACK of the first other priority, and the information carried on the first PUSCH), which is carried on the first PUSCH, so as to ensure the decoding performance of the other information carried on the first PUSCH.

Alternatively, the DAI information may correspond to a group of DAIs. This DAI information may correspond to a single UL DAI and may correspond to 2 bits when the first other priority HARQ-ACK relates only to TB-granular HARQ-ACK feedback; when the HARQ-ACK feedback of TB granularity and the HARQ-ACK feedback of CBG granularity are related at the same time, the DAI information may correspond to two UL DAIs and may correspond to 4 bits, where the first UL DAI corresponds to the first sub-codebook and may correspond to the first 2 bits, and the second UL DAI corresponds to the second sub-codebook and may correspond to the second 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 first other priorities carried in the first PUSCH with a HARQ-ACK bit sequence of the first target priority, and encoding 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, coding and mapping the DAI information of the first other priority 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 bit sequence obtained by the concatenation may be encoded and mapped. Optionally, in the 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 specified position specified by a protocol or 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 by using the same processing parameters and processing procedures as those of the HARQ-ACK bit sequence of the first target priority.

The information determining method of the embodiment of the application further includes:

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

As a sixth optional implementation manner, the determining, according to the first DAI, a DAI of a 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 simultaneously used as a DAI for HARQ-ACK application of two priorities. Optionally, the base station may schedule and ensure that the HARQ-ACKs of two priorities both meet or match the first DAI, or the base station may not do the above-mentioned guarantee, but when indicating the first DAI, select a proper DAI value to ensure that the HARQ-ACKs of two priorities can be completely multiplexed, and there may be a tail redundancy bit in the HARQ-ACK multiplexing of a certain priority.

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

The information determining method of the embodiment of the application receives first DCI used for scheduling a first PUSCH, wherein the first DCI comprises a first DAI, and the first PUSCH corresponds to a first priority; and determining the DAI applied by the first HARQ-ACK which needs to be multiplexed on the first PUSCH according to the first DAI, 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 and transmitted on the PUSCH with the first priority, the HARQ-ACK bit sequence corresponding to the first HARQ-ACK can be generated according to the determined DAI, the reliability of the HARQ-ACK multiplexing transmission is further improved, and the performances of PUSCH transmission and PDSCH transmission are further improved.
