Description

[Technical field]

[0001] This application relates to the field of communications, and in particular to an uplink acknowledgement information transmission method and apparatus. [Background technology]

[0002] Hybrid Automatic Repeat Request (HARQ) is a technique for implementing reliable data transmission by using an acknowledgement mechanism between a network device and a terminal device. HARQ-Acknowledgement (ACK) information indicates whether the terminal device has received data successfully or not. HARQ-ACK information includes ACK and Negative Acknowledgement (NACK). ACK indicates that the terminal device has received the correct data, and NACK indicates that the data received by the terminal device is abnormal.

[0003] Currently, when receiving multiple Physical Downlink Shared Channels (PDSCHs), a terminal device may generate multiple semi-static codebooks (i.e., Type-1 HARQ-ACK codebooks, hereinafter referred to as HARQ-ACK codebooks for short) for the multiple PDSCHs. Each HARQ-ACK codebook includes some HARQ-ACK information of the multiple PDSCHs. Then, the terminal device can report the multiple HARQ-ACK codebooks to a network device by using one or more Physical Uplink Shared Channels (PUSCHs) or Physical Uplink Control Channels (PUCCHs) resources. The network device determines whether to retransmit the PDSCH based on the HARQ-ACK codebooks.

[0004] However, in the above technical solution, a large amount of resources is used when a terminal device reports multiple HARQ-ACK codebooks, resulting in low resource utilization. Summary of the Invention

[0005] This application provides an uplink acknowledgement information transmission method and apparatus to solve the problem of large amount of resources being consumed when multiple HARQ-ACK codebooks are reported, thereby improving resource utilization.

[0006] In order to achieve the aforementioned objectives, the following technical solutions are used in this application:

[0007] According to a first aspect, an uplink acknowledgement information transmitting method is provided, and applied to a terminal device. The uplink acknowledgement information transmitting method includes:

[0008] The terminal device may obtain a plurality of first hybrid HARQ-ACK codebooks, where each of the plurality of first HARQ-ACK codebooks includes HARQ-ACK information of at least one downlink data channel, each of the first HARQ-ACK codebooks corresponds to one first radio network temporary identifier RNTI, and the first RNTIs corresponding to the first HARQ-ACK codebooks are different. Then, the terminal device may transmit a physical uplink channel to the network device, where the physical uplink channel carries a second HARQ-ACK codebook, where the second HARQ-ACK codebook includes at least one of the plurality of first HARQ-ACK codebooks concatenated in a preset order, and the preset order is determined based on the plurality of first RNTIs corresponding to the plurality of first HARQ-ACK codebooks.

[0009] Based on the above technical solution, after the terminal device acquires multiple first HARQ-ACK codebooks, the terminal device may transmit a physical uplink channel carrying a second HARQ-ACK codebook. Wherein, the second HARQ-ACK codebook includes at least one first HARQ-ACK codebook concatenated in a pre-configured order. In other words, the physical uplink channel transmitted by the terminal device carries multiple first HARQ-ACK codebooks. In this way, the terminal device can report multiple HARQ-ACK codebooks by using one resource, so that the resources consumed when multiple HARQ-ACK codebooks are reported are reduced, thereby improving resource utilization.

[0010] In addition, the preset order is determined based on a plurality of first RNTIs corresponding to a plurality of first HARQ-ACK codebooks, and each first HARQ-ACK codebook corresponds to one first RNTI, and the first RNTIs corresponding to the first HARQ-ACK codebooks are different. In this way, after the terminal device transmits a physical uplink channel carrying a second HARQ-ACK codebook, the network device can distinguish the plurality of first HARQ-ACK codebooks based on different first RNTIs, and then determine whether to retransmit the downlink data channel. Therefore, in this solution, the network device can avoid retransmitting a downlink data channel normally received by the terminal device, or the network device does not retransmit a downlink data channel abnormally received by the terminal device, thereby improving communication quality and resource utilization.

[0011] In relation to the first aspect, in a possible design, the plurality of first HARQ-ACK codebooks may include a third HARQ-ACK codebook and a fourth HARQ-ACK codebook, where the third HARQ-ACK codebook includes HARQ-ACK information of the at least one first downlink data channel, and the fourth HARQ-ACK codebook includes HARQ-ACK information of the at least one second downlink data channel, and there is an intersection between the time domain resources occupied by the at least one first downlink data channel and the time domain resources occupied by the at least one second downlink data channel.

[0012] In relation to the first aspect, in another possible design, the method further includes: acquiring, by the terminal device, indication information, where the indication information instructs the terminal device to concatenate at least one of the multiple first HARQ-ACK codebooks in a preset order; and then, based on the indication information, concatenating at least one of the multiple first HARQ-ACK codebooks in a preset order to acquire a second HARQ-ACK codebook.

[0013] In other words, the manner in which the terminal device concatenates multiple first HARQ-ACK codebooks is determined based on the indication information. In this way, the terminal device can concatenate multiple first HARQ-ACK codebooks based on the indication information.

[0014] In relation to the first aspect, in another possible design, the method further includes: the indication information includes a first value or a second value; when the indication information includes the first value, the terminal device concatenates a plurality of first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook.

[0015] In other words, when the indication information includes a first value, the terminal device may concatenate each of the multiple first HARQ-ACK codebooks. In this way, the second HARQ-ACK codebook can include complete HARQ-ACK codebook information. In this way, the network device can also determine HARQ-ACK information corresponding to each downlink data channel based on the second HARQ-ACK codebook, and then determine whether to retransmit the downlink data channel. Therefore, in this embodiment of the application, the network device can avoid retransmitting a downlink data channel that is normally received by the terminal device, or the network device can avoid not retransmitting a downlink data channel that is abnormally received by the terminal device, so that resource waste is reduced and communication quality is improved.

[0016] In relation to the first aspect, in another possible design, the method further includes: if the indication information includes a second value, the terminal device removes HARQ-ACK information of the at least one first downlink data channel from the third HARQ-ACK codebook, and concatenates the processed third HARQ-ACK codebook and the first HARQ-ACK codebook other than the third HARQ-ACK codebook in the multiple first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook. Alternatively, if the indication information includes a second value, the terminal device removes HARQ-ACK information of the at least one second downlink data channel from the fourth HARQ-ACK codebook, and concatenates the processed fourth HARQ-ACK codebook and the first HARQ-ACK codebook other than the fourth HARQ-ACK codebook in the multiple first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook.

[0017] Specifically, the terminal device can remove PDSCH reception opportunities (i.e., corresponding HARQ-ACK information) whose time domain resources have intersections from higher-ranked (or lower-ranked) codebooks. In this way, the amount of bits reported to the network device can be reduced, thereby reducing the air interface resource overhead.

[0018] In relation to the first aspect, in another possible design, the method in which "the terminal device may acquire the indication information" includes: the terminal device receives higher layer signaling, where the higher layer signaling includes the indication information; alternatively, the terminal device receives downlink control information DCI, where the DCI includes the indication information; alternatively, the terminal device acquires capability information of the terminal device, where the capability information indicates whether the terminal device supports frequency division multiplexing, and the capability information includes the indication information.

[0061] In order to facilitate understanding of the technical solutions in this application, some technical terms are explained below.

[0062] 1. Hybrid Automatic Repeat Request (HARQ)

[0063] HARQ is a hybrid use of Forward Error Correction (FEC) coding technique and Automatic Repeat Request (ARQ) in a cellular communication system to ensure reliable data transmission. Specifically, a transmitting end sends a data packet to a receiving end. After receiving the data packet, the receiving end processes the data packet to obtain a processing result. The receiving end feeds back HARQ-ACK information to the transmitting end based on the processing result. After receiving the HARQ-ACK information, the transmitting end demodulates the HARQ-ACK information and decides whether to resend the data packet to the receiving end or send a new data packet to the receiving end.

[0064] 2. Quasi-static codebook

[0065] The semi-static codebook includes the HARQ-ACK feedback information of at least one PDSCH. The following steps are required to generate the semi-static codebook:

[0066] Step 1: Determine an uplink slot number, where the target uplink slot corresponding to the uplink slot number is the slot in which the HARQ-ACK feedback information is sent.

[0067] Step 2: Determine a feedback window. The feedback window may be represented by a K1 table. A downlink transmission set corresponding to a slot for transmitting HARQ-ACK is determined based on a preconfigured K1 table and a PDSCH candidate time domain resource set. The K1 table indicates a slot interval between a slot in which a downlink transmission in which HARQ-ACK feedback needs to be performed is located and a slot in which the HARQ-ACK is transmitted. Different K1 tables may be selected according to whether the search space of the terminal device has the ability to detect the downlink control information (DCI) to be determined.

[0068] For example, the K1 table is {3,4,5}. As shown in FIG. 1, the slot number of the target uplink slot is 9. When K1 is 3, the slot number is 6. When K1 is 4, the slot number is 5. When K1 is 5, the slot number is 4. Specifically, the terminal device may transmit HARQ-ACK feedback information of PDSCHs received in three slots with slot numbers 4, 5, and 6 in the target uplink slot.

[0069] Step 3: Determine the slot type of the slot corresponding to the K1 table, where the slot type includes a downlink slot and an uplink slot.

[0070] Step 4: Determine the number of non-uplink slots in the corresponding slots in the K1 table.

[0071] The maximum set of PDSCHs that can be scheduled in a slot is determined by traversing each slot corresponding to the K1 table. The symbol positions (i.e., time domain positions) at which PDSCHs can be scheduled depend on the time domain allocation list pdsch-TimeDomainAllocationList set by Radio Resource Control (RRC), and the time domain allocation list includes k0, mapping type, and starting symbol and position. K0 indicates the slot interval between the downlink scheduling DCI and the PDSCHs scheduled by the DCI. The mapping type indicates the mapping type of the PDSCH. The starting symbol and position indicate the Start and Length Indicator Value (SLIV).

[0072] For example, the time domain allocation list may be expressed as follows:

number

[0073] For the PDSCH in each slot, the terminal device determines the symbol position conflict based on the PDSCH starting symbol and the number of symbols obtained through calculation, and excludes the PDSCH that conflicts with the uplink symbol. For example, as shown in FIG. 2, one slot includes four possible scheduled PDSCHs. D represents the downlink symbol, F represents the flexible symbol, and U represents the uplink symbol. Among the four PDSCHs included in the slot, the first three PDSCHs PDSCH0, PDSCH1, and PDSCH2 are included in the symbols D and F, and only PDSCH3 has an intersection with the uplink symbol. In this case, PDSCH3 is excluded from the PDSCH set that can be scheduled. Finally, the terminal device records all PDSCH sets that can be scheduled simultaneously in the feedback window.

[0074] When receiving multiple PDSCHs, the terminal device generates and obtains one HARQ-ACK information for each PDSCH. Then, the terminal device can report multiple HARQ-ACK information to the network device by using multiple PUSCH resources, and the network device determines whether to retransmit the PDSCH based on the HARQ-ACK information corresponding to each PDSCH. In this way, when the terminal device reports multiple HARQ-ACK information, many resources are used. As a result, the resource utilization rate is low. Currently, the resource utilization rate can usually be improved by using the following two conventional techniques:

[0075] In the prior art 1, when a terminal device reports to a network device its capability for receiving multiple unicast PDSCHs in one slot, the terminal device may receive multiple unicast PDSCHs in the slot. Then, the terminal device can group the received multiple unicast PDSCHs based on each unicast PDSCH receiving opportunity. Each group of PDSCHs includes at least one unicast PDSCH, and there is an intersection between the time domain resources of the multiple unicast PDSCHs in each group of PDSCHs. Then, the terminal device can generate one piece of HARQ-ACK information for each group of PDSCHs, and concatenate the multiple HARQ-ACK information to form one piece of HARQ-ACK information. Finally, the terminal device can transmit the concatenated HARQ-ACK information to the network device by using one PUSCH resource.

[0076] However, in the above technical solution, the multiple unicast PDSCHs in each group can only feedback one HARQ-ACK information. When the HARQ-ACK information of the multiple unicast PDSCHs in a group is different, specifically, in the multiple unicast PDSCHs in a group, when the HARQ-ACK information corresponding to some unicast PDSCHs is ACK and the HARQ-ACK information corresponding to some unicast PDSCHs is NACK, the terminal device can only feedback ACK or NACK. In this way, the network device can retransmit the PDSCH that is normally received by the terminal device, or the network device does not retransmit the PDSCH that is abnormally received by the terminal device. As a result, the resources of the network device are wasted, or the terminal device loses data.

[0077] In the prior art 2, the 3rd Generation Partnership Project (3 rdIn the Multiple Transmission Reception Point (MTRP) technology of the Third Generation Partnership Project (3GPP), PDSCHs that are separately scheduled by multiple pieces of DCI are supported in jointly forming a quasi-static codebook, and one PUCCH or PUSCH resource is used to report the quasi-static codebook to a network device.

[0078] For example, when receiving multiple PDSCHs, the terminal device may generate two quasi-static codebooks. In addition, each quasi-static codebook corresponds to one control resource pool (Control-Resource Set, CORESET) index. The terminal device sorts the two quasi-static codebooks based on the corresponding CORESET index, and generates one codebook. After the terminal device reports the generated codebooks to the network device, the network device can distinguish between the two quasi-static codebooks based on the CORESET index, and then decide whether to retransmit the PDSCH.

[0079] However, if the time domain resources of the two PDSCHs are repeated and the DCIs for scheduling the two PDSCHs are placed in the same CORESET (i.e., have the same CORESET index), the CORESET indexes of the HARQ-ACK information of the two PDSCHs are the same. The network device cannot distinguish between the HARQ-ACK information corresponding to each PDSCH based on the CORESET index. As a result, the network device cannot determine whether the terminal device has received each PDSCH normally. In this way, the network device can retransmit the PDSCHs that are normally received by the terminal device, or the network device does not retransmit the PDSCHs that are abnormally received by the terminal device. As a result, the resources of the network device are wasted or the terminal device loses data.

[0080] In conclusion, it can be seen that in the above-mentioned prior art, when the time domain resources of multiple PDSCHs are repeated, the network device cannot determine whether the terminal device receives each PDSCH successfully.

[0081] Therefore, an embodiment of this application provides an uplink acknowledgement information transmitting method. Before the uplink acknowledgement information transmitting method in the embodiment of this application is described, the network architecture and service scenario in the embodiment of this application are first described.

[0087] It should be noted that the uplink acknowledgement information transmission method provided in the embodiment of this application is applicable between the terminal device and the network device shown in Figure 3. For specific implementation, please refer to the following method embodiment. The details will not be described again here.

[0088] It should be noted that the solutions in the embodiments of this application may further be applied to another communication system, and the corresponding names may alternatively be replaced with names of corresponding functions in another communication system.

[0089] It should be understood that Fig. 3 is merely a simplified schematic diagram according to an example for ease of understanding. The communication system may further include other network devices and / or other terminal devices not shown in Fig. 3.

[0090] With reference to the accompanying drawings, the following describes in detail the uplink acknowledgement information transmitting method provided in the embodiments of this application.

[0091] For example, Figure 4 is a schematic flow chart of an uplink acknowledgement information transmission method according to one embodiment of this application. The uplink acknowledgement information transmission method is applicable to the communication between the terminal device and the network device shown in Figure 3. As shown in Figure 4, the uplink acknowledgement information transmission method includes the following steps:

[0092] S401: A terminal device acquires a plurality of first HARQ-ACK codebooks.

[0093] Each of the multiple first HARQ-ACK codebooks includes HARQ-ACK information of at least one downlink data channel. In other words, one first HARQ-ACK codebook includes at least one HARQ-ACK information. For example, the multiple first HARQ-ACK codebooks include HARQ-ACK codebook A and HARQ-ACK codebook B. HARQ-ACK codebook A includes HARQ-ACK information 0 of downlink data channel 0, HARQ-ACK information 1 of downlink data channel 1, and HARQ-ACK information 2 of downlink data channel 2. HARQ-ACK codebook B includes HARQ-ACK information 3 of downlink data channel 3, and HARQ-ACK information 4 of downlink data channel 4.

[0094] It should be noted that the downlink data channel may be a PDSCH, a Physical Broadcast Channel (PBCH), etc. This is not limited in this embodiment of the present application. In this embodiment of the present application, an example in which the downlink data channel is a PDSCH is used to describe the method in this embodiment of the present application.

[0095] In this embodiment of the application, the Cyclic Redundancy Check (CRC) of the downlink data channel is scrambled by using a first Radio Network Temporary Identifier (RNTI).

[0096] It should be noted that the RNTIs of the downlink data channels in one HARQ-ACK codebook are the same. The RNTIs of the downlink data channels in different HARQ-ACK codebooks are different. That is, each first HARQ-ACK codebook corresponds to one first wireless network temporary identifier RNTI. In addition, the first RNTIs corresponding to the first HARQ-ACK codebooks are different. For example, HARQ-ACK codebook A includes HARQ-ACK information 0 of PDSCH0, HARQ-ACK information 1 of PDSCH1, and HARQ-ACK information 2 of PDSCH2. When the RNTI values ​​of PDSCH0, PDSCH1, and PDSCH2 are 003D, the value of the RNTI corresponding to HARQ-ACK codebook A is 003D. HARQ-ACK codebook B includes HARQ-ACK information 3 of PDSCH3, and HARQ-ACK information 4 of PDSCH4. When the RNTI values ​​of PDSCH3 and PDSCH4 are F111, the RNTI corresponding to HARQ-ACK codebook B is F111.

[0097] In a possible implementation, the terminal device can generate multiple first HARQ-ACK codebooks in a target uplink slot, and the target uplink slot is a slot in which the multiple first HARQ-ACK codebooks are transmitted.

[0098] The multiple first HARQ-ACK codebooks may be configured based on the same K1 table or may be configured based on different K1 tables, which is not limited in this embodiment of the application. The K1 table indicates a slot interval between a slot in which a downlink transmission for which HARQ-ACK feedback needs to be performed is located and a target uplink slot.

[0099] S402: The terminal device transmits a physical uplink channel to the network device.

[0100] The physical uplink channel may be a PUCCH or a PUSCH. The physical uplink channel carries a second HARQ-ACK codebook. The second HARQ-ACK codebook includes at least one of the multiple first HARQ-ACK codebooks concatenated in a preconfigured order. In other words, the second HARQ-ACK codebook may include multiple first HARQ-ACK codebooks, or may include some of the multiple first HARQ-ACK codebooks.

[0101] In this embodiment of the application, the preset order is determined based on a plurality of first RNTIs corresponding to a plurality of first HARQ-ACK codebooks, where the first RNTIs include a Cell Radio Network Temporary Identifier (C-RNTI) and / or a Group Radio Network Temporary Identifier (G-RNTI).

[0102] It should be noted that the HARQ-ACK codebook corresponding to the C-RNTI is a unicast codebook, and the HARQ-ACK codebook corresponding to the G-RNTI is a multicast codebook or a broadcast codebook. In this embodiment of the present application, an example in which the HARQ-ACK codebook corresponding to the G-RNTI is a multicast codebook is used to describe the method in this embodiment of the present application.

[0103] In some embodiments, the plurality of first HARQ-ACK codebooks may include one unicast codebook and one multicast codebook. The preset order may be such that the first HARQ-ACK codebook corresponding to the C-RNTI is before the first HARQ-ACK codebook corresponding to the G-RNTI, i.e., the unicast codebook is before the multicast codebook. Alternatively, the preset order may be such that the first HARQ-ACK codebook corresponding to the C-RNTI is after the first HARQ-ACK codebook corresponding to the G-RNTI, i.e., the unicast codebook is after the multicast codebook.

[0104] In some other embodiments, the multiple first HARQ-ACK codebooks may include multiple multicast codebooks. The preset order may be that the first HARQ-ACK codebooks corresponding to the multiple G-RNTIs are arranged in descending order of the G-RNTIs corresponding to the first HARQ-ACK codebooks. In other words, the multiple multicast codebooks are arranged in descending order of the G-RNTIs corresponding to the multicast codebooks. Alternatively, the first HARQ-ACK codebooks corresponding to the multiple G-RNTIs are arranged in ascending order of the G-RNTIs corresponding to the first HARQ-ACK codebooks. In other words, the multiple multicast codebooks are arranged in ascending order of the G-RNTIs corresponding to the multicast codebooks.

[0105] In some other embodiments, the multiple first HARQ-ACK codebooks may include one unicast codebook and multiple multicast codebooks, in which case the preset order may be that the first HARQ-ACK codebook corresponding to the C-RNTI is before the first HARQ-ACK codebook corresponding to the G-RNTI (or the first HARQ-ACK codebook corresponding to the C-RNTI is after the first HARQ-ACK codebook corresponding to the G-RNTI), and the first HARQ-ACK codebooks corresponding to the multiple G-RNTIs are arranged in descending order of the G-RNTIs corresponding to the first HARQ-ACK codebooks. Alternatively, the preset order may be that the first HARQ-ACK codebook corresponding to the C-RNTI is before the first HARQ-ACK codebook corresponding to the G-RNTI (or the first HARQ-ACK codebook corresponding to the C-RNTI is after the first HARQ-ACK codebook corresponding to the G-RNTI), and the first HARQ-ACK codebooks corresponding to the multiple G-RNTIs are arranged in ascending order of the G-RNTIs corresponding to the first HARQ-ACK codebook. Alternatively, the preset order may be that the first HARQ-ACK codebook corresponding to the C-RNTI and the first HARQ-ACK codebook corresponding to the multiple G-RNTIs are arranged in descending order of the RNTIs corresponding to the first HARQ-ACK codebook. In other words, the unicast codebook and the multicast codebook are arranged in descending order of the RNTIs corresponding to the codebooks. Alternatively, the first HARQ-ACK codebook corresponding to the C-RNTI and the first HARQ-ACK codebooks corresponding to the multiple G-RNTIs are arranged in ascending order of the RNTIs corresponding to the first HARQ-ACK codebook. In other words, the unicast codebook and the multicast codebook are arranged in ascending order of the RNTIs corresponding to the codebooks.

[0106] For example, the multiple first HARQ-ACK codebooks include a unicast codebook a, a multicast codebook a, and a multicast codebook b. The RNTI corresponding to the unicast codebook a is 003D, the value of the RNTI corresponding to the multicast codebook a is 0041, and the value of the RNTI corresponding to the multicast codebook b is 0051. If the pre-configured order is that the first HARQ-ACK codebook corresponding to the C-RNTI is before the first HARQ-ACK codebook corresponding to the G-RNTI, and the first HARQ-ACK codebooks corresponding to the multiple G-RNTIs are arranged in descending order of the G-RNTI corresponding to the first HARQ-ACK codebook, as shown in Figure 5, the unicast codebook a is at the top, the multicast codebook b is between the unicast codebook a and the multicast codebook a, and the multicast codebook a is at the end. Each bit (Binary digit, bit) corresponds to one HARQ-ACK information.

[0107] S403: The network device receives a physical uplink channel from the terminal device.

[0108] Based on the above technical solution, after the terminal device acquires multiple first HARQ-ACK codebooks, the terminal device may transmit a physical uplink channel carrying a second HARQ-ACK codebook. Wherein, the second HARQ-ACK codebook includes at least one first HARQ-ACK codebook concatenated in a pre-configured order. In other words, the physical uplink channel transmitted by the terminal device carries multiple first HARQ-ACK codebooks. In this way, the terminal device can report multiple HARQ-ACK codebooks by using one resource, so that the resources consumed when multiple HARQ-ACK codebooks are reported are reduced, thereby improving resource utilization.

[0109] In addition, the preset order is determined based on a plurality of first RNTIs corresponding to a plurality of first HARQ-ACK codebooks, and each first HARQ-ACK codebook corresponds to one first RNTI, and the first RNTIs corresponding to the first HARQ-ACK codebooks are different. In this way, after the terminal device transmits a physical uplink channel carrying a second HARQ-ACK codebook, the network device can distinguish the plurality of first HARQ-ACK codebooks based on the different first RNTIs, and then decide whether to retransmit the downlink data channel. Therefore, in this solution, the network device can avoid retransmitting a downlink data channel normally received by the terminal device, or the network device does not retransmit a downlink data channel abnormally received by the terminal device, thereby improving communication quality and resource utilization.

[0110] It should be noted that multiple first HARQ-ACK codebooks may be configured based on the same SLIV or different SLIVs, which is not limited in this embodiment of the application. SLIV represents the starting index of the time domain symbol occupied by the downlink data channel and the length of the occupied time domain symbol, where SLIV is an integer and 0≦SLIV≦127. For example, SLIV being 1 can indicate that the starting index of the time domain symbol occupied by the PDSCH is 2, and the length of the occupied time domain symbol is 5.

[0111] The terminal device can obtain the start index of the time domain symbol occupied by the downlink data channel and the length of the occupied time domain symbol according to the SLIV and the preset scheme. When there is no intersection between the time domain symbols occupied by different downlink data channels, there is no intersection between the time domain resources of different downlink data channels. When different downlink data channels are in the same slot and there is an intersection between the occupied time domain symbols, there is an intersection between the time domain resources of different downlink data channels. For example, as shown in Figure 6, the start index of the time domain symbol occupied by downlink data channel a is 5 and the length of the occupied time domain symbol is 6. The start index of the time domain symbol occupied by downlink data channel b is 3 and the length of the occupied time domain symbol is 5. There is an intersection between the time domain resource of downlink data channel a and the time domain resource of downlink data channel b.

[0112] It should be noted that for multiple downlink data channels whose time domain resources have intersections, the multiple downlink data channels may correspond to one HARQ-ACK information. In this way, the network device can retransmit the PDSCH that is normally received by the terminal device, or the network device does not retransmit the PDSCH that is abnormally received by the terminal device. As a result, the resource of the network device is wasted, or the terminal device loses data.

[0113] In this embodiment of the application, in the plurality of first HARQ-ACK codebooks, there may be an intersection between the time domain resources occupied by the downlink data channels corresponding to different codebooks. For example, the plurality of first HARQ-ACK codebooks include a third HARQ-ACK codebook and a fourth HARQ-ACK codebook. The third HARQ-ACK codebook includes HARQ-ACK information of at least one first downlink data channel, and the fourth HARQ-ACK codebook includes HARQ-ACK information of at least one second downlink data channel. There is an intersection between the time domain resources occupied by the at least one first downlink data channel and the time domain resources occupied by the at least one second downlink data channel. Specifically, the first downlink data channel and the second downlink data channel may correspond to one HARQ-ACK information.

[0114] Therefore, in some embodiments, the terminal device can determine whether there is indication information in the terminal device to perform different concatenation for a plurality of first HARQ-ACK codebooks. The indication information instructs the terminal device to concatenate at least one of the plurality of first HARQ-ACK codebooks in a pre-configured order. Figure 7A is a schematic flowchart of an uplink acknowledgement information transmission method according to an embodiment of this application. As shown in Figure 7A, the uplink acknowledgement information transmission method includes the following steps:

[0115] S701: The terminal device determines whether indication information exists in the terminal device.

[0116] The indication information instructs the terminal device to concatenate at least one of the first HARQ-ACK codebooks in a preset order. The indication information may be 1 bit or 2 bits. The number of bits of the indication information is not limited in this embodiment of the present application.

[0117] It should be noted that, when the indication information exists in the terminal device, frequency division multiplexing can be performed between different downlink data channels. For example, frequency division multiplexing can be performed between a PDSCH carrying broadcast data and a PDSCH carrying multicast data. In another example, frequency division multiplexing can be performed between different PDSCHs carrying multicast data. When the indication information does not exist in the terminal device, frequency division multiplexing cannot be performed between different downlink data channels.

[0118] It will be understood that different concatenation schemes can be implemented in multiple first HARQ-ACK codebooks by the terminal device determining whether or not indication information exists in the terminal device, i.e., whether or not frequency division multiplexing can be performed between different downlink data channels.

[0119] In a possible design, if the indication information exists in the terminal device, the terminal device executes S702. If the indication information does not exist in the terminal device, the terminal device executes S703.

[0120] It should be noted that the order in which the terminal device executes S701 and S401 is not limited in this embodiment of the present application. In other words, the terminal device may execute S701 first, and then execute S401. Alternatively, the terminal device may execute S401 first, and then execute S701. Alternatively, the terminal device may execute S401 and S701 simultaneously.

[0121] S702: The terminal device concatenates a plurality of first HARQ-ACK codebooks in a preset order based on the indication information to obtain a second HARQ-ACK codebook.

[0122] It should be noted that when the indication information exists in the terminal device, frequency division multiplexing can be performed among multiple downlink data channels. In this way, even if there is an intersection between the time domain resources occupied by the downlink data channels corresponding to HARQ-ACK information in different HARQ-ACK codebooks, each downlink data channel whose occupied time domain resources have an intersection can still correspond to one HARQ-ACK information.

[0123] For example, the third HARQ-ACK codebook is a unicast codebook a, and the fourth HARQ-ACK codebook is a multicast codebook b. The unicast codebook a includes five PDSCH receiving occasions, which are receiving occasions #0, #1, #2, #3, and #4, respectively. The multicast codebook b includes five PDSCH receiving occasions, which are receiving occasions #10, #11, #12, #13, and #14, respectively. It is assumed that the slot indexes corresponding to the receiving occasion #2 of the unicast codebook a and the receiving occasion #12 of the multicast codebook b are the same, an intersection exists between the time domain resources corresponding to the SLIV, and there is indication information in the terminal device. Specifically, an intersection exists between the time domain resources occupied by the PDSCH corresponding to the receiving occasion #2 of the unicast codebook a and the time domain resources occupied by the PDSCH corresponding to the receiving occasion #12 of the multicast codebook b. As shown in FIG. 8, the terminal device may concatenate the unicast codebook a and the multicast codebook b in a preset order (eg, an order in which the unicast codebook is before the multicast codebook).

[0124] It will be understood that when the indication information exists in the terminal device, the terminal device may send a complete HARQ-ACK codebook to the network device. In this way, the network device can determine HARQ-ACK information corresponding to each downlink data channel based on the HARQ-ACK codebook, and then decide whether to retransmit the downlink data channel. Therefore, in this embodiment of the present application, the network device can avoid retransmitting the downlink data channel normally received by the terminal device, or the network device not retransmitting the downlink data channel abnormally received by the terminal device, so that resource waste is reduced and communication quality is improved.

[0125] In some embodiments, the terminal device may obtain the indication information before transmitting the physical uplink channel to the network device. As shown in FIG. 7B, before S402, the uplink confirmation information transmitting method includes the following steps:

[0126] S401a: The network device sends instruction information to the terminal device.

[0127] The network device sending the instruction information to the terminal device includes the following manner (a) and manner (b).

[0128] In the manner (a), the network device sends higher layer signaling to the terminal device, where the higher layer signaling includes indication information.

[0129] In the manner (b), the network device sends a DCI to the terminal device, where the DCI includes indication information.

[0130] S401b: The terminal device acquires indication information.

[0131] The terminal device obtains the indication information in the following three ways:

[0132] In manner 1, the terminal device receives higher layer signaling, where the higher layer signaling includes indication information.

[0133] In the second method, the terminal device receives DCI, where the DCI includes indication information. The indication information is obtained by using the DCI, so that the manner of concatenating multiple first HARQ-ACK codebooks can be dynamically indicated. This makes the concatenation method more flexible.

[0134] In manner 3, the terminal device acquires capability information of the terminal device, where the capability information indicates whether the terminal device supports frequency division multiplexing, and the capability information includes indication information.

[0135] In conclusion, the terminal device can obtain the indication information in multiple manners, so that the terminal device obtains the indication information in a more flexible manner.

[0136] In some embodiments, the terminal device may further transmit capability information to the network device. The network device may obtain the capability information from the terminal device.

[0137] S703: The terminal device concatenates at least one of the multiple first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook.

[0138] It should be noted that if there is no indication information in the terminal device, frequency division multiplexing cannot be performed among multiple downlink data channels. In this way, there is an intersection between the time domain resources occupied by the downlink data channels corresponding to the HARQ-ACK information in different HARQ-ACK codebooks, and multiple downlink data channels whose occupied time domain resources have an intersection can correspond to one HARQ-ACK information.

[0139] In a possible implementation, the terminal device removes HARQ-ACK information of at least one first downlink data channel from the third HARQ-ACK codebook, and concatenates the processed third HARQ-ACK codebook and the first HARQ-ACK codebooks other than the third HARQ-ACK codebook in the multiple first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook.

[0140] For example, the third HARQ-ACK codebook is a unicast codebook a, and the fourth HARQ-ACK codebook is a multicast codebook b. The unicast codebook a includes five PDSCH receiving opportunities, which are receiving opportunities #0, #1, #2, #3, and #4, respectively. The unicast codebook b includes five PDSCH receiving opportunities, which are receiving opportunities #10, #11, #12, #13, and #14, respectively. It is assumed that there is no indication information in the terminal device, the slot index corresponding to the receiving opportunity #2 of the unicast codebook a and the receiving opportunity #12 of the multicast codebook b are the same, and an intersection exists between the time domain resources corresponding to the SLIVs. Specifically, there is an intersection between the time domain resource occupied by the PDSCH corresponding to reception opportunity #2 of unicast codebook a and the time domain resource occupied by the PDSCH corresponding to reception opportunity #12 of multicast codebook b. As shown in Figure 9A, the terminal device can remove the HARQ-ACK information of the PDSCH corresponding to reception opportunity #2 of unicast codebook a from unicast codebook a, and then concatenate the processed unicast codebook a and multicast codebook b in a preset order (e.g., the order in which the unicast codebook is before the multicast codebook).

[0141] In conclusion, it can be seen that the terminal device can remove PDSCH reception opportunities (i.e., those corresponding to HARQ-ACK information) whose time domain resources have intersections from the top ranked codebook. In this way, the amount of bits reported to the network device can be reduced, thereby reducing the air interface resource overhead.

[0142] In another possible implementation, the terminal device removes HARQ-ACK information of at least one second downlink data channel from the fourth HARQ-ACK codebook, and concatenates the processed fourth HARQ-ACK codebook and a first HARQ-ACK codebook other than the fourth HARQ-ACK codebook among the multiple first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook.

[0143] For example, the third HARQ-ACK codebook is a unicast codebook a, and the fourth HARQ-ACK codebook is a multicast codebook b. The unicast codebook a includes five PDSCH reception opportunities, which are reception opportunities #0, #1, #2, #3, and #4, respectively. The unicast codebook b includes five PDSCH reception opportunities, which are reception opportunities #10, #11, #12, #13, and #14, respectively. It is assumed that there is no indication information in the terminal device, the slot index corresponding to reception opportunity #2 of the unicast codebook a and reception opportunity #12 of the multicast codebook b are the same, and there is an intersection between the time domain resources corresponding to the SLIV. Specifically, there is an intersection between the time domain resources occupied by the PDSCH corresponding to reception opportunity #2 of the unicast codebook a and the time domain resources occupied by the PDSCH corresponding to reception opportunity #12 of the multicast codebook b. As shown in FIG. 9B, the terminal device can remove the HARQ-ACK information of the PDSCH corresponding to reception opportunity #12 of multicast codebook b from multicast codebook b, and then concatenate the processed multicast codebook b and unicast codebook a in a pre-configured order (e.g., the unicast codebook is before the multicast codebook).

[0144] In conclusion, it can be seen that the terminal device may remove PDSCH reception opportunities (i.e., those corresponding to HARQ-ACK information) whose time domain resources have intersections from the backward ranked codebook. In this way, the amount of bits reported to the network device can be reduced, thereby reducing the air interface resource overhead.

[0145] It should be noted that the reserved HARQ-ACK information is not limited in this embodiment of this application. Specifically, the HARQ-ACK information corresponding to the PDSCH whose time domain resource has an intersection can be ACK or NACK. However, in most cases, when the HARQ-ACK information corresponding to the PDSCH whose time domain resource has an intersection includes NACK, the NACK can be reserved preferentially, and the reception opportunity of the PDSCH whose time domain resource has an intersection in another codebook is eliminated. In this way, it can be ensured that the terminal device can report that the received downlink data channel is in an abnormal state, so that the network device retransmits the downlink data channel that is abnormally received by the terminal device to improve communication quality.

[0146] Based on the above technical solution, the terminal device can determine whether there is indication information in the terminal device. The indication information instructs the terminal device to concatenate at least one of the multiple first HARQ-ACK codebooks in a preset order. In this way, in this embodiment of the application, the terminal device can perform different concatenation methods for the multiple first HARQ-ACK codebooks according to whether there is indication information in the terminal device.

[0147] In some other embodiments, after obtaining the indication information, the terminal device may concatenate at least one of the plurality of first HARQ-ACK codebooks in a preset order based on the indication information to obtain a second HARQ-ACK codebook. The indication information includes a first value or a second value. The first value and the second value may be any two different values, for example, the first value may be 1 and the second value may be 0.

[0148] In a possible implementation, after obtaining the indication information, the terminal device determines whether the value included in the indication information is a first value.

[0149] In a possible design, when the indication information includes a first value, the terminal device may concatenate a plurality of first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook. For example, when the indication information includes a first value, frequency division multiplexing may be performed between different downlink data channels, and the terminal device may concatenate a plurality of first HARQ-ACK codebooks in a preset order to obtain a second HARQ-ACK codebook.
