technical field

The present invention relates to the field of communication technologies, and in particular, to an information determination method, an information indication method, a terminal and a network side device.

Background technique

In Ultra-reliable and Low Latency Communications (URLLC), when the time domain of transmission resources overlaps, the uplink transmission with higher priority is always guaranteed first, and the lower priority is discarded. upstream transmission.

In order to ensure the performance of lower priority uplink transmission, especially the transmission performance of Hybrid Automatic Repeat reQuest-ACK (HARQ-ACK), which is the most important uplink control information (Uplink Control Information, UCI), It is necessary to consider the multiplexing of uplink transmission across priorities. For example, it is necessary to consider multiplexing HARQ-ACKs corresponding to different priorities on the Physical Uplink Shared Channel (PUSCH).

When considering multiplexing HARQ-ACK on PUSCH across priorities, the following scenarios can be considered:

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

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

Case 2: PUSCH of priority j does not need to multiplex HARQ-ACK of 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 applicable to the same priority HARQ-ACK multiplexing transmission. When HARQ-ACK with different priorities needs to be multiplexed and transmitted on the PUSCH, because there is no reference UL-DAI, the transmission reliability cannot be guaranteed, and the rate matching may affect the transmission of the PUSCH where it is located. In addition, the reliability of HARQ-ACK transmission will also have a great impact on downlink data transmission performance.

The base station in the NR system is taken as an example, but the specific type of the base station is not limited.

In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is first 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 time, it determines each PDSCH based on the predefined rules and the scheduling of PDSCH transmission on single/multiple carriers that need to report HARQ-ACK at this feedback time. The corresponding relationship between transmission and certain bits in the HARQ-ACK bit sequence of the organization, this operation is called constructing the HARQ-ACK Codebook. When the semi-persistent scheduling (SPS) PDSCH release is indicated by downlink control information (Downlink Control Information, DCI), the UE is also required to use the HARQ-ACK bit to confirm its reception to ensure that both sides are active for the SPS PDSCH. The understanding of the state remains consistent.

Optionally, two HARQ-ACK Codebook schemes can be used in the wireless communication system: a semi-static codebook (Type-1) and a dynamic codebook (Type-2), the former provides feedback for all possible DCI indications and PDSCH transmissions , which is mainly used to ensure transmission reliability, and the feedback overhead is large. The latter only provides feedback for the actual DCI indication and PDSCH transmission, and the feedback overhead is small, and the transmission reliability will be affected to a certain extent when the DCI missed detection is common.

The dynamic codebook reserves HARQ-ACK feedback bits for each actually used DAI value by counting the DAI of the actually scheduled PDSCH transmission/SPS PDSCH release indication. If the PDSCH allocation indication or SPS PDSCH release indication corresponding to the DAI is not received, the corresponding feedback bit is set to NACK, otherwise the corresponding HARQ-ACK feedback bit is set according to the decoding result of the PDSCH transmission corresponding to each PDSCH allocation indication, For the detected SPS PDSCH release indication, set the corresponding feedback bit to ACK.

DAI uses a limited number of bits (currently a single DAI generally occupies 2 bits) to indicate. In order to expand its indication range, a modulo operation is introduced, that is, it starts counting sequentially from 1, and then modulo obtains the DAI corresponding to a certain count value. value.

When the UE is only configured with a single serving cell, the aforementioned DAI is only for a single carrier, and is counted one by one according to the time sequence indicated by the DCI, which can be called counter DAI (referred to as C-DAI). When the UE is configured with multiple serving cells, in order to further increase reliability, Total DAI (referred to as T-DAI) is newly introduced to indicate the number of all DCI indications received up to the current time domain detection position, including the current time All DCI indications received by the domain detection location on each serving cell, so the value of T-DAI will be updated only when the time domain detection location changes. The combination of T-DAI and C-DAI can effectively avoid the loss of DCI indication on one or some serving cells at a certain time domain detection location (as long as the DCI indications on all serving cells are not lost). The transmission understands inconsistencies.

The HARQ-ACK Codebook is generally transmitted on the PUCCH, and the time domain and frequency domain information of the PUCCH is indicated in the DCI (with one exception: the HARQ-ACK of the SPS PDSCH feedback the frequency domain information of the PUCCH can be configured by the higher layer). When the PUCCH transmission overlaps with a certain PUSCH transmission in the time domain, part or all of the UCI carried on the PUCCH will be multiplexed for transmission on the PUSCH. For the HARQ-ACK dynamic codebook, the missed detection of DCI will affect the construction of the HARQ-ACK Codebook, including the number of HARQ-ACK bits contained in the Codebook, and the number of HARQ-ACK bits will affect the number of HARQ-ACK bits occupied during multiplexing and transmission on the PUSCH. time-frequency resources, thereby affecting the time-frequency demapping and decoding of other data transmissions (eg, UL-SCH) on the PUSCH. In order to avoid the impact caused by the inconsistent understanding of the above HARQ-ACK bits between the UE and the network side, the DAI corresponding to the HARQ-ACK Codebook for multiplexing transmission can be indicated in the DCI format 0_1 of the scheduling PUSCH, which can be called UL DAI. UL DAI is mainly used by the UE to determine the number of HARQ-ACK bits of the HARQ-ACK Codebook, and can be used to determine the missed detection of the DCI corresponding to the HARQ-ACK bits at the end of the HARQ-ACK Codebook. When the HARQ-ACK Codebook only involves HARQ-ACK feedback at Transport Block (TB) granularity (that is, no two sub-codebooks are involved), only a single UL DAI is indicated in DCI format 0_1 (by the DCI field "1st downlink assignment" "index" indication), corresponding to a single HARQ-ACK Codebook, when the HARQ-ACK Codebook involves both TB-granular HARQ-ACK feedback and Code Block Group (CBG)-granularity HARQ-ACK feedback (that is, by two When sub-codebooks are sequentially cascaded), two UL DAIs are indicated in DCI format 0_1 at the same time, of which the first UL DAI (indicated by the DCI field "1st downlink assignment index") is applied to the first sub-codebook, and the first UL DAI is applied to the first sub-codebook. Two UL DAIs (indicated by the DCI field "2nd downlink assignment index") are applied to the second sub-codebook.

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

In the URLLC scenario, for the enhancement of UCI, a 2-level priority for HARQ-ACK is introduced. When DCI format 0_1/0_2 schedules PUSCH, the priority index (priority index) corresponding to the scheduled PUSCH transmission can be indicated by the 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 priority indicator field in the DCI can indicate its corresponding HARQ-ACK feedback and the priority index (0 or 1) corresponding to the PUCCH transmission carrying this feedback. When a PUSCH/PUCCH transmission does not indicate its corresponding priority index, the default value of priority index 0 is used. Only when the corresponding priorities are the same, the overlapping PUSCH/PUCCH related processing is performed. Otherwise, if the PUSCH/PUSCH transmissions of different priorities overlap (overlap), the transmission corresponding to priority index 0 is discarded, and only priority index 1 is transmitted. corresponding transmission. The UCI is assumed to be the same as the priority of the PUCCH/PUSCH carrying this UCI. The priority index 0 here can be understood as a lower priority, and the priority index 1 can be understood as a higher priority. When time domain overlap occurs, the uplink transmission corresponding to priority index 1 has a higher priority than the uplink transmission corresponding to priority index 0.

The information determination method provided by the embodiments of the present application will be 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 a method for determining information, which is executed by a terminal, and the method includes:

Step 201: Receive first downlink control information DCI for scheduling a first physical uplink shared channel PUSCH, where the first DCI includes a first downlink allocation index DAI, and the first PUSCH corresponds to a first priority.

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

Step 202: According to the first DAI, determine the DAI applied by the first HARQ-ACK acknowledgement HARQ-ACK, the first HARQ-ACK includes the HARQ-ACK of the second priority, and the second priority is the same as the HARQ-ACK of the second priority. The first priority is different.

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

Step 203: Generate a HARQ-ACK bit sequence corresponding to the first HARQ-ACK according to the determined DAI.

When the HARQ-ACK of the second priority needs to be multiplexed on the PUSCH of the first priority, the corresponding HARQ-ACK bits are generated according to the DAI of the HARQ-ACK application of the second priority determined by the above-mentioned first DAI sequence. The HARQ-ACK bit sequence corresponding to the first HARQ-ACK may be the HARQ-ACK bit sequence corresponding only to the HARQ-ACK of the second priority, or may be the HARQ-ACK corresponding to the HARQ-ACK of the first priority at the same time. -The ACK bit sequence, and the HARQ-ACK bit sequence corresponding to the HARQ-ACK of the second priority, are not limited here.

In the information determination method of the embodiment of the present application, a first DCI for scheduling a first PUSCH is received, the first DCI includes a first DAI, and the first PUSCH corresponds to a first priority; according to the first DAI, it is determined that the DAI applied by the first HARQ-ACK multiplexed on the first PUSCH, the first HARQ-ACK including the HARQ-ACK of the second priority, so that the HARQ-ACK of the second priority is on the PUSCH of the first priority During multiplexing transmission, the HARQ-ACK bit sequence corresponding to the first HARQ-ACK may be generated according to the determined DAI, thereby improving the reliability of HARQ-ACK multiplexing transmission.

As a first optional implementation manner, according to the first DAI, determining the DAI of the first HARQ-ACK application for HARQ-ACK acknowledgment includes:

The first DAI is used as the DAI for the HARQ-ACK application of the second priority.

In this implementation, optionally, the UE does not expect to simultaneously multiplex HARQ-ACKs corresponding to two priorities on the same PUSCH, that is, only multiplex HARQ-ACKs with a priority different from that of the PUSCH on the PUSCH - ACK, eg HARQ-ACK of the second priority is multiplexed on PUSCH only. The specific implementation can be guaranteed by the base station scheduling.

Optionally, when the value of the above-mentioned first DAI is 4, and the UE does not detect any downlink DCI or SPS PDSCH corresponding to HARQ-ACK that needs to be multiplexed on this PUSCH, the UE does not multiplex HARQ-ACK on this 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 optional implementation manner, the first DAI includes a first group of DAI and a second group of DAI;

The determining, according to the first DAI, the DAI of the first HARQ-ACK application for HARQ-ACK acknowledgment includes:

The second set of DAI is used as the DAI for the HARQ-ACK application of the second priority.

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

It should be noted that a group of DAIs in the embodiments of the present application only involves HARQ-ACK feedback of TB (Transport Block, transport block) granularity (that is, the HARQ-ACK that needs to be multiplexed only includes feedback for TB-level downlink allocations). HARQ-ACK), corresponding to a single UL DAI; HARQ-ACK feedback involving both TB granularity and CBG (Code Block Group, code block group) granularity HARQ-ACK feedback (that is, the HARQ-ACK that needs to be multiplexed contains both HARQ-ACK for TB-level downlink allocation feedback, and HARQ-ACK for CBG-level downlink allocation feedback, the CBG-level downlink allocation here can be understood as when the upper layer configures the target downlink carrier for DCI scheduling to enable CBG-based retransmission, PDSCH transmission indicated by non-fallback downlink DCI, at this time, based on PDSCH transmission, each possible corresponding CBG feeds back the corresponding HARQ-ACK; the HARQ-ACK that needs to be multiplexed corresponds to two HARQ-ACK sub-codebooks sub-codebook, When the first sub-codebook corresponds to HARQ-ACK feedback of TB granularity, and the second sub-codebook corresponds to HARQ-ACK feedback of CBG granularity), it corresponds to two UL DAIs, of which the first UL DAI corresponds to the first sub -codebook, the second UL DAI corresponds to the second sub-codebook.

Optionally, the above-mentioned first group of DAI corresponds to priority index 0, or a lower priority, that is, the above-mentioned first group of DAI is used as the DAI of the HARQ-ACK application corresponding to priority index 0; the above-mentioned second group of DAI corresponds to priority index 1, or Higher priority, that is, the above-mentioned second group of DAI is used as the DAI of the HARQ-ACK application corresponding to priority index 1.

Optionally, the above-mentioned first group of DAI corresponds to a priority corresponding to PUSCH scheduling, and the second group of DAI corresponds to another priority that is different from PUSCH scheduling.

Optionally, whether the above-mentioned first DAI includes the second group of DAI may be determined based on a protocol specification or a high-level configuration.

Optionally, for a dynamic codebook or an enhanced dynamic codebook, when the value of DAI corresponding to a certain priority is 4, and it is not detected that the HARQ-ACK corresponding to this priority needs to be transmitted (for example, it is not detected that the HARQ-ACK corresponding to this priority needs to be transmitted When the DL DCI of the HARQ-ACK is fed back in the slot/sub-slot where the PUSCH transmission is located, and/or the SPS PDSCH of the HARQ-ACK needs to be fed back in the slot/sub-slot where the PUSCH transmission is located), this UL is not included The HARQ-ACK corresponding to this priority is multiplexed on the PUSCH transmission scheduled by DCI.

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

As a third optional implementation manner, according to the first DAI, determining the DAI of the first HARQ-ACK application for HARQ-ACK acknowledgment includes:

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

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

Wherein, the first target priority is one of the following:

the first priority;

the higher 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, the scheme corresponding to the third optional implementation manner, and the scheme for determining the DAI of the first HARQ-ACK application corresponding to the above step 202 are two parallel schemes, that is, the third optional implementation manner corresponds to programs can be implemented independently.

It can be understood that when the first priority and the second priority correspond to priority index 0 and 1 respectively, or respectively correspond to priority index 1 and 0, the first priority and the second priority The higher priority in the corresponding priority index 1, the lower priority of the first priority and the second priority corresponding 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. The above-mentioned first DAI is used as the DAI of the HARQ-ACK application corresponding to the first priority, and the DAI of the HARQ-ACK application of the second priority can be determined based on the detection of the downlink DCI corresponding to the HARQ-ACK of the second priority.

For another example, if the above-mentioned 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 can be based on the HARQ-ACK of the other priority The detection situation of the corresponding downlink DCI is determined.

As a fourth optional implementation manner, according to the first DAI, determining the DAI of the first HARQ-ACK application to confirm the HARQ-ACK includes:

Determine the second DAI according to the detection situation of the downlink DCI corresponding to the HARQ-ACK of the first priority;

Determine the third DAI according to the detection situation of the downlink DCI corresponding to the HARQ-ACK of the second priority;

In the case where the sum of the second DAI and the third DAI is equal to the value of the first DAI, the second DAI is used as the DAI for the HARQ-ACK application of the first priority, and the The third DAI is used as the DAI for the HARQ-ACK application of the second priority.

In this implementation manner, under the ideal situation that there is no downlink DCI missed detection, the terminal expects or considers that the value of the first DAI is based on the sum of the second DAI and the third DAI (which may be the sum of the sum. The value after the 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 of the second DAI and the third DAI (considering the modulo operation) is equal to the value of the first DAI, the terminal can determine the downlink DCI corresponding to the first priority and the downlink DCI corresponding to the second priority There is no missed detection in the downlink DCI of the terminal. Correspondingly, the terminal can use the second DAI as the DAI of the HARQ-ACK application of the first priority, and use the third DAI as the HARQ of the second priority. -ACK DAI applied. When the sum of the second DAI and the third DAI (considering the modulo operation) is not equal to the value of the first DAI, the terminal may determine the downlink DCI corresponding to the first priority, and/or the second The downlink DCI corresponding to the priority has missed detection. At this time, the terminal can determine the other priority based on the DAI a determined by the downlink DCI detection corresponding to one priority a (for example, a higher priority) and the first DAI. DAI b for the HARQ-ACK application of b. DAI a is applied to HARQ-ACK of priority a.

Here, the DAI of the HARQ-ACK application of the two priorities can be determined based on the detection of the downlink DCI corresponding to each priority, and it is ensured that the sum of the DAI of the HARQ-ACK application of the two priorities satisfies the above-mentioned first DAI value. For example, based on the corresponding operations described above, the terminal ensures that the sum of the DAIs of the HARQ-ACK applications of the two priorities satisfies the value of the above-mentioned first DAI.

As a fifth optional implementation manner, according to the first DAI, determining the DAI of the first HARQ-ACK application for HARQ-ACK acknowledgment includes:

According to the detection situation of the downlink DCI corresponding to the first target priority, determine the DAI of the HARQ-ACK application of the first target priority;

According to the DAI of the HARQ-ACK application of the first target priority and the first DAI, determine the DAI of the HARQ-ACK application of the first other priority;

Wherein, the first target priority is one of the following:

the first priority;

The network side can determine the number of HARQ-ACK bits of the first other priority based on the decoded DAI information of the first other priority and the detection 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 other information carried on the first PUSCH (except for the first target priority).
