Background technique

In Ultra-reliable and Low Latency Communications (Ultra-reliable and Low Latency Communications, URLLC), when time-domain overlap occurs in transmission resources, the uplink transmission with higher priority is always given priority, and the lower-priority one is discarded. Uplink transmission.

In order to ensure the performance of the lower priority uplink transmission, especially the transmission performance of the most important Hybrid Automatic RepeatreQuest-ACK (HARQ-ACK) in the uplink control information (Uplink Control Information, UCI), it is necessary to consider For uplink transmission multiplexing across priorities, for example, it is necessary to consider multiplexing HARQ-ACKs corresponding to different priorities on a 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 with priority j needs to multiplex HARQ-ACK with priority j;

Case 2: PUSCH with priority j does not need to multiplex HARQ-ACK with priority j;

For the above scenarios, the uplink-downlink assignment index (Uplink-Downlink AssignmentIndex, UL-DAI) indicated in the uplink-downlink control information (Uplink-Downlink ControlInformation, UL-DCI) for scheduling PUSCH transmission is applicable to HARQ- ACK multiplexing transmission, when HARQ-ACKs with different priorities need to be multiplexed and transmitted on PUSCH, because there is no reference UL-DAI, transmission reliability cannot be guaranteed, and rate matching may affect the reliability of the PUSCH transmission where it is located , in addition, the reliability of HARQ-ACK transmission will also have a great impact on downlink data transmission performance.

Fig. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application is applicable.

Wherein, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (LaptopComputer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), handheld computer, netbook, ultra-mobile personal computer (ultra-mobile personal computer, UMPC), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted device ( VUE), Pedestrian Terminal (PUE) and other terminal-side devices, wearable devices include: bracelets, earphones, glasses, etc. It should be noted that, the embodiment of the present application does not limit the specific type of the terminal 11 .

It should be noted that in the embodiment of the application, only NR The base station in the 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 descriptions are given first.

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 the predefined rules and the scheduling of PDSCH transmission on a single/multiple carriers that need to report HARQ-ACK at this feedback time, determine each PDSCH The corresponding relationship between transmission and a certain/certain bit in the organized HARQ-ACK bit sequence is called constructing the HARQ-ACK Codebook. When the semi-persistent scheduling (Semi-persistent Scheduling, SPS) PDSCH is released through the 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 state remains the same.

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

The dynamic codebook reserves the HARQ-ACK feedback bit for each actually used DAI value by counting the DAI for 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, set the corresponding feedback bit to NACK; otherwise, set the corresponding HARQ-ACK feedback bit according to the decoding result of the PDSCH transmission corresponding to each PDSCH allocation indication, For the detected SPS PDSCH release indication, set its corresponding feedback bit as 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 takes the modulus to obtain 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 counted one by one according to the time sequence indicated by the DCI, which can be called counter DAI (C-DAI for short). When the UE is configured with multiple serving cells, in order to further increase reliability, a new Total DAI (T-DAI for short) is newly introduced, which is used to indicate the number of all DCI indications received up to the current time domain detection position, including the current time domain The domain detection location receives all DCI indications 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 indications on one or some serving cells in a certain time domain detection position (as long as the DCI indications on not all serving cells are lost) and the UE and gNB for DCI indication The transport understands the case of inconsistencies.

The HARQ-ACK Codebook is generally transmitted on the PUCCH, and the time domain and frequency domain information of the PUCCH are indicated in the DCI (with one exception: the HARQ-ACK feedback PUCCH frequency domain information of the SPS PDSCH can be configured by higher layers). 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 on the PUSCH for transmission. For the HARQ-ACK dynamic codebook, because the DCI missing detection 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 multiplexing transmission on the PUSCH. Time-frequency resources, thereby affecting time-frequency demapping and decoding of other data transmissions (eg, UL-SCH) on the PUSCH. In order to avoid the influence caused by the inconsistent understanding of the number of HARQ-ACK bits on 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 scheduling PUSCH, which can be called UL DAI. UL DAI is mainly used for the UE to determine the number of HARQ-ACK bits in the HARQ-ACK Codebook, and can be used to determine the missing 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 the transport block (Transport Block, TB) granularity (that is, does not involve two sub-codebooks), 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 HARQ-ACK feedback at the TB granularity and HARQ-ACK feedback at the code block group (Code Block Group, CBG) granularity (that is, composed of two When sub-codebooks are cascaded in sequence), DCI format 0_1 indicates two UL DAIs 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 second Two UL DAIs (indicated by the DCI field "2nd downlink assignment index") apply to the second sub-codebook.

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

In the URLLC scenario, for the enhancement of UCI, a two-level priority (2-level priority) for HARQ-ACK is introduced. When DCI format 0_1/0_2 schedules PUSCH, the priority indicator (priority indicator) field in DCI can indicate the priority index (priority index) corresponding to the scheduled PUSCH transmission, and the value is 0 or 1. When 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 corresponding priority index (0 or 1) of the PUCCH transmission carrying this feedback. When a PUSCH/PUCCH transmission does not indicate its corresponding priority index, the default value priority index 0 is used. Only when the corresponding priorities are the same, the overlapping (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 that bears the 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 embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in Figure 2, the 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, the first DCI includes a first downlink allocation index DAI, and the first PUSCH corresponds to a first priority.

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

Step 202: According to the first DAI, determine the DAI of the first hybrid automatic repeat request confirmation HARQ-ACK application, the first HARQ-ACK includes the second priority HARQ-ACK, and the second priority is the same as the first DAI The above first priority is different.

Wherein, the first HARQ-ACK is the 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 includes 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 contained 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.

In the case that the HARQ-ACK of the second priority needs to be multiplexed on the PUSCH of the first priority, the corresponding HARQ-ACK bit is generated according to the DAI applied to the HARQ-ACK of the second priority determined by the first DAI sequence. The HARQ-ACK bit sequence corresponding to the first HARQ-ACK may be the HARQ-ACK bit sequence corresponding to the HARQ-ACK of the second priority only, or the HARQ bit sequence 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, the first DCI for scheduling the first PUSCH is received, the first DCI includes the first DAI, and the first PUSCH corresponds to the first priority; according to the first DAI, it is determined that the The DAI applied to the first HARQ-ACK multiplexed on the first PUSCH, the first HARQ-ACK includes 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 can be generated according to the determined DAI, thereby improving the reliability of HARQ-ACK multiplexing transmission.

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

The first DAI is used as the DAI applied to the HARQ-ACK of the second priority.

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

Optionally, when the value of the above-mentioned first DAI is 4, and the UE does not detect any downlink DCI or SPS PDSCH that needs to multiplex the corresponding HARQ-ACK 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 DAIs and a second group of DAIs;

According to the first DAI, determining the first hybrid automatic repeat request to confirm the DAI of the HARQ-ACK application includes:

The second group of DAIs is used as the DAIs applied to 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, it 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 embodiment of the present application only involves HARQ-ACK feedback at the TB (Transport Block, transport block) granularity (that is, the HARQ-ACK that needs to be multiplexed only includes feedback for TB-level downlink allocation) HARQ-ACK), corresponding to a single UL DAI; HARQ-ACK feedback involving TB granularity and CBG (Code Block Group, code block group) granular HARQ-ACK feedback (that is, the HARQ-ACK that needs to be multiplexed contains both The HARQ-ACK for TB-level downlink allocation feedback and the HARQ-ACK for CBG-level downlink allocation feedback. The CBG-level downlink allocation here can be understood as when the upper layer configures the CBG-based retransmission for the target downlink carrier scheduled by DCI. For the PDSCH transmission indicated by the non-backoff downlink DCI, at this time, each possible corresponding CBG based on the PDSCH transmission feeds back the corresponding HARQ-ACK; the HARQ-ACK that needs to be multiplexed corresponds to two HARQ-ACK sub-codebooks, Among them, the first sub-codebook corresponds to the HARQ-ACK feedback of TB granularity, and the second sub-codebook corresponds to the HARQ-ACK feedback of CBG granularity), corresponding to two UL DAIs, and 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 lower priority High 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 first group of DAIs corresponds to the priority corresponding to the PUSCH scheduling, and the second group of DAIs corresponds to another priority different from the PUSCH scheduling.

Optionally, whether the first DAI includes the second group of DAIs may be determined based on protocol regulations or high-level configurations.

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 that needs to be transmitted in When the DL DCI of HARQ-ACK is fed back in the time slot/sub-slot where this PUSCH transmission is located, and/or the SPS PDSCH of HARQ-ACK needs to be fed back in the time slot/sub-slot where this PUSCH transmission is located), it is not in this UL The HARQ-ACK corresponding to this priority is multiplexed on the PUSCH transmission scheduled by the 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 in the protocol this situation).

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

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

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

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

said first priority;

the higher of said first priority and said second priority;

the lower of said first priority and said second priority;

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

Here, the solution corresponding to the third optional implementation, the solution for determining the DAI of the first HARQ-ACK application corresponding to the above step 202 is two parallel solutions, that is, the third optional implementation corresponds to The program 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, in the first priority and the second priority The higher priority of the corresponds to priority index 1, and the lower priority of said first priority and said 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 the PUSCH transmission scheduled by it is the first priority j. The above 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 may be determined based on the detection situation of the downlink DCI corresponding to the HARQ-ACK of the second priority.

For another example, the above-mentioned first DAI is used as the DAI of the HARQ-ACK application corresponding to the higher priority or the lower priority, then the DAI of the HARQ-ACK application of another priority can be based on the HARQ-ACK of the other priority The detection status of the corresponding downlink DCI is determined.

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

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

Determine a 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, the terminal expects or believes that the value of the first DAI is based on the sum of the second DAI and the third DAI under the ideal condition that there is no missed detection of downlink DCI (the 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 of the downlink DCI, and accordingly, the terminal can use the second DAI as the DAI for the first priority HARQ-ACK application, and use the third DAI as the second priority HARQ -ACK applied DAI. 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 can determine the downlink DCI corresponding to the first priority, and/or the second The downlink DCI corresponding to the priority has missing detection. At this time, the terminal can determine another priority based on the DAI a determined by the downlink DCI detection corresponding to one of the priorities 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 DAIs of HARQ-ACK applications with two priorities can be determined based on the detection of downlink DCI corresponding to each priority, and ensure that the sum of the DAIs of HARQ-ACK applications with two priorities satisfies the first DAI above. value. For example, based on the corresponding operations described above, the terminal ensures that the sum of the DAIs of the two priority HARQ-ACK applications satisfies the value of the first DAI above.

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

said first priority;

the higher of said first priority and said second priority;

the lower of said first priority and said 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 the HARQ-ACK application of the first priority The sum of the DAI and the DAI of the HARQ-ACK application of the second priority is equal to the value of the first DAI.

In this implementation, under the ideal situation that there is no missing detection of downlink DCI, the terminal expects or believes that the value of the first DAI is based on the DAI of the HARQ-ACK application of the first target priority and the first other priority The sum of the DAI applied to the HARQ-ACK of the first target priority (may be the value after the sum is moduloed, for example, the DAI applied to the HARQ-ACK of the first target priority and the HARQ of the first other priority - The sum of the DAI applied by the ACK is modulo 4, and the obtained value is set as the value of the first DAI).

This DAI information can be decoded before the HARQ-ACK corresponding to the first other priority carried by the first PUSCH, and is used for the terminal to indicate to the network side the first other priority carried on the first PUSCH The number of bits corresponding to the corresponding HARQ-ACK, thereby notifying the network side of the amount of resources used to carry the HARQ-ACK corresponding to the first other priority on the first PUSCH, and assisting the network side in decoding other PUSCHs carried on the first PUSCH information to improve the performance of PUSCH detection. A possible implementation on the network side is that, after receiving the first PUSCH, the network side first extracts the code corresponding to the HARQ-ACK of the first target priority and/or the DAI information of the first other priority. bit sequence, and decode the HARQ-ACK of the first target priority and/or the DAI information of the first other priority. Here it can be assumed that the protocol stipulates or the higher layer configures the 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, and the network side Based on the starting mapping position, the detection situation of the downlink DCI corresponding to the first target priority, the DAI of the HARQ-ACK application of the first target priority, the number of bits of DAI information, and other configuration parameters, the first target can be determined The number of HARQ-ACK bits of the priority, and the length of the encoded bit sequence and the end 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 decoded DAI information of the first other priority, combined with 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 know exactly other information carried on the first PUSCH (except the first target priority) The mapping position and mapping length of HARQ-ACK and/or the DAI information of the first other priority, and the information carried on the first PUSCH other than the HARQ-ACK of the first other priority) ensure Decoding performance of other information carried on the first PUSCH.
