Description

Technical Field

[0001] This application belongs to the field of communication technology, and in particular relates to a transmission processing method, apparatus and related equipment. Background Technology

[0002] In communication systems, uplink and downlink transmissions are typically scheduled using time-frequency resources. For example, the Physical Uplink Shared Channel (PUSCH) can be scheduled dynamically or semi-statically. Currently, time-domain scheduling is based on time slots, meaning that a PUSCH is usually scheduled for transmission on a single time slot. When channel conditions are constant, and the size of the transport block (TB) transmitted on a single time slot increases, coverage may be limited due to the Orthogonal Frequency Division Multiplexing (OFDM) symbol limit of the scheduled time slot. Summary of the Invention

[0003] This application provides a transmission processing method, apparatus, and related equipment that can solve the problem that the limitation of the number of OFDM symbols in the scheduled time slots may lead to limited coverage.

Furthermore, the transmission throughput can be increased when using the same bit rate. Therefore, this embodiment can improve transmission performance. Attached Figure Description

The base station is not limited to specific technical terms. It should be noted that in this embodiment of the application, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0039] It should be understood that the transmission processing method of this application can be applied to both uplink and downlink transmission. For ease of understanding, the following will describe some aspects of the embodiments of this application in the case of PUSCH:

[0040] I. The starting position and length of symbols for time-domain resource allocation.

[0041] For repetition type A transmission, the corresponding mapping type can be mapping type A or mapping type B;

[0042] If the mapping type is A, then S = 0, L = 4~14, S+L = 4~14; where S represents the index value of the starting symbol and L represents the allocation length.

[0043] If the mapping type is B, then S = 0~13, L = 1~14, and S+L = 1~14.

[0044] For repetition type B transmission, the corresponding mapping type can only be mapping type B, S = 0~13, L = 1~14, S+L = 1~27.

[0045] II. Time and Frequency Resource Allocation.

[0046] The time-domain resource configuration includes the following parts:

[0047] (1) Slot offset K2;

[0048] (2) Start and length indicator value (SLIV), or start symbol index S and allocation length L; wherein, the SLIV is used for repetition type A, and the S and L are used for repetition type B.

[0049] (3) mapping type;

[0050] (4) Number of repetitions, if repetition transmission is configured.

[0051] 3. For repetition type A transmissions, S and L are determined based on the SLIV value obtained according to the first calculation method. The first calculation method is expressed as follows:

[0052] If (L-1)≤7, then SLIV=14*(L-1)+S;

[0053] Otherwise, SLIV = 14*(14-L+1)+(14-1-S);

[0054] Where 0 < L ≤ 14-S.

[0055] Based on the above formula, the values ​​of SLIV and the correspondence between S and L can be obtained as shown in Table 1 below.

[0056] Table 1:

[0057]

[0058]

[0059] IV. Uplink Control Information (UCI).

[0060] UCI includes the following types: Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK), Channel State Information (CSI) reporting, and Scheduling Request (SR).

[0061] The aforementioned UCIs can be transmitted on the periodic Physical Uplink Control Channel (PUCCH) resources, while CSIs can be transmitted on the PUSCH via Downlink Control Information (DCI) triggering. If the PUCCH and / or PUSCH resources used to transmit different UCIs overlap in time, the UE needs to multiplex the UCIs transmitted on multiple channels onto the same PUCCH or PUSCH resource.

[0062] If the PUCCH for UCI transmission and the PUSCH for UE data transmission overlap in the time domain, the UE will multiplex the UCI onto the PUSCH for transmission. This PUSCH can be a scheduled PUSCH or a configured grant PUSCH.

[0063] Optionally, if a UCI on one PUCCH is multiplexed onto another PUCCH resource, the information bits transmitted on the two PUCCHs are concatenated and then encoded and transmitted together.

[0064] If the UCI on the PUCCH is multiplexed onto the PUSCH for transmission, the data portions of the UCI and PUSCH are encoded separately and transmitted in a mapped manner. When the UCI is multiplexed onto the PUSCH, the network device configures a beta offset value for the PUSCH to determine the number of modulation symbols occupied by the UCI in the PUCCH. The larger the beta offset value, the more resources the UCI occupies on the multiplexed PUSCH. However, the final number of modulation symbols occupied by the UCI cannot exceed a certain threshold. This threshold is obtained by scaling the number of all available resource elements (REs) after removing overhead from the PUSCH resources by a certain ratio. The scaling factor is alpha, which is configured by higher-layer parameters.

[0065] The transmission processing method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0066] Please see Figure 2 , Figure 2 This is a flowchart of a transmission processing method provided in an embodiment of this application. The method is executed by the sending end, such as... Figure 2 As shown, it includes the following steps:

[0067] Step 201: Determine the target time-frequency resources for scheduling based on the time-domain resource allocation instruction;

[0068] In this embodiment, the aforementioned time-frequency resource allocation indication refers to a scheduling indication sent by the network device to the terminal, used to schedule uplink or downlink transmission. Optionally, the aforementioned sending end can be understood as a terminal or a network device. When the sending end is a terminal, before the step of determining the target time-frequency resource to be scheduled based on the time-domain resource allocation indication, the method may further include: receiving the time-domain resource allocation indication sent by the network device. When the sending end is a network device, the method may further include: sending the time-domain resource allocation indication.

[0069] Optionally, when the sender is a terminal, the aforementioned target time-frequency resources are used for uplink transmission, and the aforementioned time-domain resource allocation indication can be understood as a scheduling indication for scheduling uplink transmission; when the sender is a network device, the aforementioned target resources are used for downlink transmission, and the aforementioned time-frequency resource allocation indication can be understood as a scheduling indication for scheduling downlink transmission.

[0070] Step 202: Map the transport block to the target time-frequency resource;

[0071] The target time-frequency resource occupies N time slots in the time domain, where N is an integer greater than 1.

[0072] In this embodiment, the data to be transmitted can be mapped onto a transport block. After preprocessing the transport block, the modulation symbols before mapping are obtained. These modulation symbols are then mapped onto a target time-frequency resource for transmission. The receiving end can receive the corresponding signal based on the target time-frequency resource and then demodulate it to obtain the data transmitted by the transmitting end.

[0073] The fact that the target time-frequency resources occupy N time slots in the time domain can be understood as follows: the above time-domain resource allocation indication is used to schedule an uplink or downlink transmission, occupying at least two time slots. In other words, the target time-frequency resources are used to schedule the target transmission to be transmitted in multiple time slots or across time slots, and the target transmission can be either uplink or downlink.

[0074] In this embodiment, a target time-frequency resource for scheduling is determined according to a time-domain resource allocation instruction; a transport block is mapped to the target time-frequency resource; wherein the target time-frequency resource occupies N time slots in the time domain, where N is an integer greater than 1. By mapping the transport block to at least two time slots for transmission, the transmission bit rate can be reduced and the transmission reliability improved compared to single-time-slot transmission, thus increasing the transmission coverage, while maintaining the same transport block size. Furthermore, the transmission throughput can be increased when using the same bit rate. Therefore, this embodiment can improve transmission performance.

[0075] Optionally, the time-domain resource allocation indicator is used to indicate the index value S of the starting symbol of the target time-frequency resource and the allocation length L of the target time-frequency resource.

[0076] In this application embodiment, the methods for determining S and L may include various methods, which will be described in detail below through different determination methods.

[0077] For example, in some embodiments, S and L are determined by a first start and length indicator SLIV1; wherein SLIV1 = SLIV2 + (N-1)*M, M is an integer greater than or equal to 105, and 14*(N-1) < L ≤ 14*NS, and the second start and length indicator SLIV2 satisfies at least one of the following:

[0078] In the case that (L-1)≤14*(N-1)+7, SLIV2=14*[L-1-14*(N-1)]+S;

[0079] In the case that (L-1) > 14*(N-1)+7, SLIV2 = 14*[14*N-(L-1)]+(14-1-S).

[0080] Optionally, the value of M can be 105 or 128. Ultimately, each SLIV1 value corresponds to a uniquely determined S and L. It should be understood that the calculation of SLIV1 can also be applied to the case where N=1.

[0081] The aforementioned SLIV2 can be understood as a start and length indicator. Based on the correspondence between the range of L values ​​and the calculation method of SLIV2, SLIV2 can be calculated using SLIV2 = 14*[L-1-14*(N-1)]+S and SLIV2 = 14*[14*N-(L-1)]+(14-1-S). SLIV1 is then calculated based on SLIV1 = SLIV2+(N-1)*M. Optionally, in this embodiment, the aforementioned time-domain resource allocation indicator may include the SLIV1 value, or it may include the values ​​of S and L corresponding to the SLIV1 value.

[0082] In some embodiments, the time-domain resource allocation indication includes a first indication information and a second indication information, wherein the first indication information is used to indicate N, and the second indication information is used to indicate S and a first allocation length L1, wherein L satisfies: L = L1 + 14 * (N - 1).

[0083] In this embodiment of the application, the following can be used: The second indication information indicates the number of slots occupied by time-domain resources. In this case, the aforementioned second indication information can be understood as an existing time-domain resource allocation indication, specifically indicating the first allocation length L1 and S. For example, the second indication information may include the values ​​of L1 and S determined according to the SLIV calculation method of the existing protocol, or it may include the SLIV value determined according to the aforementioned SLIV calculation method of the existing protocol. For example, the SLIV calculation method is as follows:

[0084] If (L1-1)≤7, then SLIV=14*(L1-1)+S;

[0085] Otherwise, SLIV = 14*(14-L1+1)+(14-1-S);

[0086] Where 0 < L1 ≤ 14-S.

[0087] In some embodiments, S and L are determined by a third start and length indicator SLIV3; wherein SLIV3 = 14*(L-1)+S.

[0088] In this embodiment of the application, each SLIV3 corresponds to a uniquely determined S and L. Optionally, the aforementioned time-domain resource allocation indication may include a SLIV3 value, or it may include the values ​​of S and L corresponding to the SLIV3 value, without further limitation here.

[0089] It should be understood that, in the embodiments of this application, when N equals 1, the time-domain resource allocation indication can also be determined based on SLIV3.

[0090] In some embodiments, the time-domain resource allocation indication includes a third indication information and a fourth indication information. The third indication information is used to determine the value relationship between S and L. The fourth indication information is used to indicate a fourth start and length indication SLIV4, which is used to determine S and L.

[0091] In this embodiment of the application, the relationship between the values ​​of S and L can be specifically expressed as the following two relationships:

[0092] (14*(N-1)-S)<L≤14*(N-1);

[0093] 14*(N-1)<L≤14*NS.

[0094] The calculation method of SLIV4 varies depending on the value relationship. Optionally, SLIV4 satisfies at least one of the following:

[0095] In the case that (14*(N-1)-S)<L≤14*(N-1) and (S+1)≤14*(N-2)+7, SLIV4=14*(S+1)+L-1-14*(N-2);

[0096] In the case that (14*(N-1)-S)<L≤14*(N-1) and (S+1)>14*(N-2)+7, SLIV4=14*(14-S-1)+(14*(N-1)-L);

[0097] In the case that 14*(N-1)<L≤14*NS and (L-1)≤14*(N-1)+7, SLIV4=14*(L-1-14*(N-1))+S;

[0098] In the case that 14*(N-1)<L≤14*NS and (L-1)>14*(N-1)+7, SLIV4=14*(14*N-L+1)+(14-1-S).

[0099] Furthermore, when N is greater than 1, the third indication information includes at least one bit of indication information, wherein the most significant bit or the least significant bit of the at least one bit is used to indicate the value relationship between S and L; the value relationship between S and L includes at least one of the following:

[0100] (14*(N-1)-S)<L≤14*(N-1);

[0101] 14*(N-1)<L≤14*NS.

[0102] In this embodiment of the application, the aforementioned third indication information can also be used to determine the value of N. That is, the value of N can be determined first, thus determining the first bit; then, based on the determined relationship between the values ​​of S and L, the second bit can be determined; and then the first bit and the second bit are concatenated to obtain the third indication information. The first bit can be located before or after the second bit. No further limitations are imposed here.

[0103] Optionally, the second bit can be represented by a first value (14*(N-1)-S)<L≤14*(N-1) and by a second value 14*(N-1)<L≤14*NS. The first value can be either 0 or 1, and the second value can be the other.

[0104] In one embodiment, when the length L of the target time-frequency resource is greater than 14, the size A of the transport block satisfies: B represents the intermediate transport block size calculated based on 14 symbols in the time domain, β = L / 14.

[0105] In this embodiment, when L is less than or equal to 14, the transport block size can be calculated using the traditional Transport Block Size (TBS) calculation method. The traditional TBS calculation method can be understood as calculating the transport block size based on the actual OFDM symbols occupied in the time domain. That is, the aforementioned intermediate transport block size is calculated using the traditional TBS calculation method with a maximum of 14 OFDM symbols occupied, and then the calculated B is scaled according to the value of β to obtain the final transport block size.

[0106] Optionally, in one embodiment, the step of mapping the transport block to the target time-frequency resource includes:

[0107] The transport block is divided into N sub-transport blocks according to the number of first symbols allocated in each time slot;

[0108] Each sub-transmission block is preprocessed to obtain the modulation symbols corresponding to N sub-transmission blocks;

[0109] Map the modulation symbols corresponding to the N sub-transmission blocks to the target time-frequency resource;

[0110] The first number of symbols does not include the number of OFDM symbols occupied by the demodulation reference signal (DMRS).

[0111] In this embodiment, the modulation symbol corresponding to the sub-transmission block should be understood as the modulation symbol of the sub-transmission block before mapping, that is, the modulation symbol obtained after layer mapping and precoding processing. For example, preprocessing can be performed on a unit of sub-transmission blocks within each time slot to obtain the modulation symbol before mapping corresponding to each sub-transmission, and finally mapped to the time-frequency resources of each time slot corresponding to the target time-frequency resource for transmission.

[0112] Optionally, the size of each sub-transmission block can be set according to actual needs. For example, in one embodiment, the N sub-transmission blocks are the same size.

[0113] In another embodiment, the size of each subtransmitter block is proportional to the number of the first symbols allocated within the time slot in which the subtransmitter block resides.

[0114] In other words, in this embodiment of the application, the more first symbols allocated in a time slot, the larger the size of the corresponding sub-transmission block. This ensures that the code rate transmitted in each time slot remains consistent, thus guaranteeing the reliability of the transmission.

[0115] Optionally, in another embodiment, the step of mapping the transport block to the target time-frequency resource includes:

[0116] The transmission block is preprocessed to obtain the modulation symbol corresponding to the transmission block;

[0117] The modulation symbols corresponding to the transport block are sequentially mapped onto the target time-frequency resources.

[0118] In this embodiment, the transport block can be treated as a whole and not split. Preprocessing is then performed to obtain the modulation symbols before mapping. Finally, these modulation symbols are sequentially mapped onto the time-frequency resources of each time slot in the target time-frequency resource for transmission.

[0119] It should be understood that the above preprocessing may include operations such as cyclic redundancy check (CRC), channel coding, rate matching, scrambling, modulation, layer mapping, and precoding to obtain the modulation symbols before mapping, and then resource mapping is performed.

[0120] Optionally, after the step of determining the target time-frequency resource for scheduling based on the time-domain resource allocation instruction, the method further includes:

[0121] Map the first DMRS to the target time-frequency resource;

[0122] The method for determining the time-domain location of the first DMRS includes any of the following:

[0123] The time domain location of the DMRS corresponding to each time slot is determined based on the number of OFDM symbols allocated to each time slot;

[0124] The time-domain location of the first DMRS is determined based on the number of OFDM symbols of the target time-frequency resource.

[0125] The OFDM symbol count of the target time-frequency resource can be understood as the total number of OFDM symbols scheduled, or the total number of symbols allocated to the target time-frequency resource in the N time slots. The first DMRS can be understood as the DMRS that needs to be transmitted on the target time-frequency resource in this scheduled transmission.

[0126] In this embodiment of the application, the determination of the time domain location of the first DMRS may include the following two methods.

[0127] Method 1 allows for the determination of the time domain location of the DMRS for each time slot. In other words, DMRS mapping can be performed on a time slot basis.

[0128] Method 2: When the total number of allocated OFDM symbols is greater than 14, the time domain location of the DMRS can be determined according to the total number of allocated OFDM symbols.

[0129] Regarding Method 1 above, assuming the total number of allocated OFDM symbols is 17, these 17 OFDM symbols occupy two time slots. The first time slot occupies 10 OFDM symbols, and the second time slot occupies 7 OFDM symbols. In this case, the time domain position of the DMRS symbols within the first time slot is determined according to the 10 OFDM symbols; the time domain position of the DMRS symbols within the second time slot is determined according to the 7 OFDM symbols.

[0130] Regarding method 2 above, the position of each group of DMRS symbols can be determined by grouping them into sets of 14 symbols. In other words, when the number of OFDM symbols in the target time-frequency resource is greater than 14, determining the time-domain position of the first DMRS based on the number of OFDM symbols in the target time-frequency resource includes:

[0131] The OFDM symbol count of the target time-frequency resource is divided into at least two symbol groups, with each group consisting of 14 consecutive symbols.

[0132] The time-domain location of the DMRS corresponding to each symbol group is determined according to the number of OFDM symbols in each symbol group.

[0133] Assuming a total of 17 OFDM symbols are allocated, grouping them results in two OFDM symbol groups: the first group consists of the first 14 OFDM symbols, and the second group consists of the last 3 OFDM symbols. In the first group, the time-domain location of the DMRS mapped onto those 14 OFDM symbols is determined by the number of OFDM symbols in the first group. The time-domain location of the DMRS mapped onto those 3 OFDM symbols is determined by the number of OFDM symbols in the second group.

[0134] Optionally, the mapping method of the DMRS satisfies any one of the following:

[0135] The default mapping type is B;

[0136] Mapping type A has a higher priority than mapping type B.

[0137] In this embodiment, for method 1, the DMRS mapping method can be understood as the DMRS mapping method within each time slot, and for method 2, the DMRS mapping method can be understood as the DMRS mapping method within each OFDM symbol group.

[0138] The higher priority of mapping type A over mapping type B can be understood as follows: if the conditions corresponding to mapping type A are met, DMRS mapping is performed according to mapping type A; otherwise, DMRS mapping is performed according to mapping type B. For example, for mode 1, for PUSCH transmission, if the number of OFDM symbols allocated in a certain time slot is greater than or equal to 4, and the starting symbol index is 0 (i.e., S=0), then DMRS mapping is performed according to mapping type A; otherwise, DMRS mapping is performed according to mapping type B. For mode 2, for PUSCH transmission, if the number of OFDM symbols in a certain OFDM packet is greater than or equal to 4, and the starting symbol index is 0 (i.e., S=0), then DMRS mapping is performed according to mapping type A; otherwise, DMRS mapping is performed according to mapping type B.

[0139] Furthermore, when determining the time domain location of the DMRS corresponding to each time slot based on the number of OFDM symbols allocated to each time slot, the DMRS corresponding to each time slot also satisfies the following: when the number of OFDM symbols allocated to the first time slot is 1, and the first time slot and the second time slot meet preset conditions, the DMRS is not mapped in the first time slot or is mapped only in the first time slot.

[0140] Not mapping DMRS in the first time slot can be understood as only mapping data in the first time slot, and frequency hopping is not supported in the first time slot.

[0141] It should be understood that, in the embodiments of this application, the number of DMRS symbols transmitted in the second time slot can be reduced.

[0142] Optionally, in one embodiment, the above-mentioned preset conditions include at least one of the following:

[0143] The first time slot and the second time slot use the same antenna port;

[0144] The power deviation between the antenna ports used in the first time slot and the second time slot is less than or equal to a first preset value;

[0145] The phase between the antenna ports used in the first time slot and the second time slot is continuous;

[0146] The first time slot and the second time slot use the same precoding parameters;

[0147] The first time slot and the second time slot use the same spatial filtering parameters.

[0148] It should be noted that the aforementioned target time-frequency resources can be used for uplink transmission or downlink transmission. In the following embodiments, uplink transmission is used as an example to illustrate resource conflict scenarios. For instance, if the transport block is carried on a first physical uplink shared channel (PUSCH), and the first PUSCH and the physical uplink control channel (PUCCH) overlap in the time domain, the step of mapping the transport block to the target time-frequency resources includes:

[0149] The transmission methods of the first PUSCH and PUCCH are determined based on the target information;

[0150] The target information includes at least one of the following:

[0151] PUCCH multiplexes the number of modulation symbols P that can be transmitted on the first PUSCH;

[0152] The number of OFDM symbols allocated by PUSCH in each of the N time slots;

[0153] The number of modulation symbols available for PUSCH transmission in each of the N time slots.

[0154] The P is determined by the second number of symbols when the first PUSCH and PUCCH are multiplexed, and the second number of symbols is the following minimum OFDM number of symbols:

[0155] The preset number of OFDM symbols, or the configurable maximum number of OFDM symbols when a PUSCH is multiplexed with a PUCCH in a time slot;

[0156] The number of OFDM symbols actually allocated to the first PUSCH.

[0157] Optionally, the above transmission method includes at least one of the following:

[0158] If P is greater than the number of modulation symbols available for PUSCH transmission in the third time slot, PUSCH is not transmitted in the third time slot.

[0159] If a fourth time slot exists among the N time slots, the PUCCH is multiplexed with the PUSCH of the fourth time slot;

[0160] If a fourth time slot is not present among the N time slots, at least one of the PUCCH and the first PUSCH shall not be transmitted.

[0161] The third time slot is the time slot where the first PUSCH and the PUCCH overlap, and the fourth time slot is a time slot in which the number of modulation symbols available for PUSCH transmission is greater than P.

[0162] In this embodiment, not sending PUSCH in the third time slot can be understood as simply not sending PUSCH in the third time slot, i.e., puncturing the PUSCH in the third time slot. For example, the first PUSCH is scheduled to be sent in time slots 1 and 2. Assuming that the PUSCH transmitted in time slot 1 overlaps with the aforementioned PUCCH, only the PUSCH in time slot 2 is sent. Alternatively, it can be understood as starting to send the aforementioned first PUSCH in a time slot following the third time slot. For example, the first PUSCH is scheduled to be sent in time slots 1 and 2. Assuming that the PUSCH transmitted in time slot 1 overlaps with the aforementioned PUCCH, the first PUSCH is sent in time slots 2 and 3. Here, time slots 1, 2, and 3 are three consecutive time slots, and time slot 1 is located before time slot 2.

[0163] It should be understood that N time slots may include one or more fourth time slots. In this embodiment, the PUCCH can be multiplexed with the PUSCH of any fourth time slot, and the specific multiplexing transmission location is not further limited here.

[0164] Optionally, if the PUCCH also overlaps with the second PUSCH, the transmission method includes any of the following:

[0165] The PUCCH is preferentially multiplexed into the first PUSCH;

[0166] The PUCCH is preferentially multiplexed into the second PUSCH, and the second PUSCH is scheduled to be transmitted on a time slot.

[0167] In this embodiment of the application, the first PUSCH can be understood as a multi-slot PUSCH, and the second PUSCH can be understood as a single-slot PUSCH.

[0168] To better understand this application, the implementation process of this application will be described in detail below through specific embodiments.

[0169] In the first implementation method, the transmission is scheduled to occur in two time slots, and SLIV1 is used to determine the time domain resource allocation indication.

[0170] Step 1, calculate SLIV2. This SLIV2 satisfies:

[0171] When (L-1)≤21, SLIV2=14*[L-1-14*(N-1)]+S;

[0172] In the case that (L-1)>21, SLIV2=14*[28-(L-1)]+(14-1-S);

[0173] Where 14 < L ≤ 28 - S.

[0174] Step 2, calculate SLIV1, SLIV1 = SLIV2 + M. When M equals 128, the values ​​of SLIV1 and the corresponding relationships between S and L are shown in Table 2. Therefore, when SLIV1 = 153, S = 11 and L = 16 can be uniquely determined.

[0175] Table 2:

[0176]

[0177] When M equals 105, the values ​​of SLIV1 and the corresponding relationships between S and L are shown in Table 3 below. When SLIV = 142, S = 9 and L = 17 can be uniquely determined.

[0178] Table 3:

[0179]

[0180]

[0181] Implementation method two, first use The number of slots occupied by the bits indicating the time-domain resources is represented as follows: for example, '00' represents N = 1, '01' represents N = 2, '10' represents N = 3, and '11' represents N = 4. Then, the existing SLIV method is used to indicate the slot allocation, with the default being L1 > 28. As shown in Table 1 above, assuming that SLIV = 26 indicates S = 12, L1 = 2, but N = 3. In fact, the indicated L = L1 + 14 * 2 = 30. At this time, when N = 3, the corresponding relationship between the values of SLIV, S, and L is shown in Table 4 below.

[0182]

[0183] Embodiment 3: SLIV3 is used to determine the time-domain resource allocation indication, and SLIV3 = 14 * (L - 1) + S. When the value range of L is 1 to 42 and the value of S is 0 to 13, the corresponding relationship between the values of SLIV3, S, and L is shown in Table 5 below. Among them, the filled part represents the corresponding relationship between SLIV3, S, and L when N = 2. For example, when SLIV3 = 214, S = 4 and L = 16 can be uniquely determined.

[0184] Table 5:

[0185]

[0186]

[0187] Embodiment 4: Scheduling is performed on 2 time slots, and SLIV4 is used to determine the time-domain resource allocation indication.

[0188] The third indication information is used to indicate '10' or '11' to determine N = 2. The least significant bit '0' indicates (14 - S) < L <= 14; the least significant bit '1' indicates 14 < L <= (28 - S).

[0189] In the case of (14 - S) < L <= 14, SLIV4 satisfies:

[0190] If (S + 1) <= 7, then SLIV4 = 14 * (S + 1) + L - 1;

[0191] If (S + 1) > 7, then SLIV4 = 14 * (14 - S - 1) + (14 - L).

[0192] In the case of (14 < L <= (28 - S)), SLIV4 satisfies:

[0193] If (L - 1) <= 21, then SLIV4 = 14 * (L - 1 - 14) + S;

[0194] If (L - 1) > 21, then SLIV4 = 14 * (28 - L + 1) + (14 - 1 - S).

[0195] In this embodiment, the correspondence between the values of SLIV4 and S and L is shown in Table VI below.

[0196] Table VI:

[0197]

[0198] In Table VI, the dotted-filled part indicates that the third indication information indicates '10'. When (14 - S) < L ≤ 14, the mapping relationship between all values of SLIV4 in this range and S and L; the bold part indicates that the third indication information indicates '11'. When 14 < L ≤ (28 - S), the mapping relationship between all values of SLIV4 in this range and S and L. For example, when the third indication information indicates '11' and SLIV4 = 89, S = 5 and L = 21 can be uniquely determined.

[0199] Optionally, assume that the time-domain resource allocation indication determines S = 2 and L = 16, as Figure 3 shown. In one embodiment, first calculate the intermediate TBS according to 14 symbols occupied in the time domain, denoted as TBS_temp, and scale the intermediate TBS to obtain the final factor size of β = 16 / 14.

[0200] Optionally, assume that the time-domain resource allocation indication determines S = 3 and L = 15, as Figure 4 shown. The TB occupies 2 time slots, slot 1 and slot 2. Among them, the available modulation symbols on slot 1 are 8, and the available modulation symbols on slot 2 are 3. At this time, the obtained TB can be divided into TB1 and TB2, TB1 = TB * 8 / 11, TB2 = TB * 3 / 11. After subsequent processing (such as CRC, channel coding, rate matching, scrambling, modulation, layer mapping, precoding, resource mapping, etc.), they are transmitted on part A and part B respectively.

[0201] Optionally, in another embodiment, the TB can be directly subjected to subsequent processing (such as CRC, channel coding, rate matching, scrambling, modulation, layer mapping, precoding, etc.) to obtain the modulation symbols before mapping, and then mapped and transmitted on part A and part B in sequence.

[0202] Embodiment 5, as Figure 5 shown. The PUCCH overlaps with the PUSCH in part A. When P is greater than the number of available modulation symbols in part A of the PUSCH in slot 1, excluding the overhead, such as the DMRS occupying 2 OFDM symbols and no phase tracking reference signal (Phase tracking reference signal, PTRS).

[0203] Optionally, in one embodiment, the corresponding PUSCH transmission portion is not transmitted in region A of time slot 1, while the corresponding PUSCH transmission portion continues to be transmitted in region B of time slot 2.

[0204] Optionally, in one embodiment, the corresponding PUSCH transmission portion is not transmitted in region A of time slot 1, and the corresponding PUSCH transmission portion is not transmitted in region B of time slot 2.

[0205] Optionally, in one embodiment, the PUSCH is not transmitted in region A of time slot 1, but is transmitted starting in region B of time slot 2.

[0206] Implementation method six, such as Figure 6 As shown, the PUCCH overlaps with the PUSCH in section A. When the number of available modulation symbols in regions A and B of time slots 1 and 2 of the PUSCH transmission, after removing overhead, is greater than P (e.g., DMRS occupies 2 OFDM symbols, no PTRS overhead), the PUCCH can be multiplexed with the PUSCH in time slot 1 for transmission.

[0207] Implementation method seven, such as Figure 7 As shown, the PUCCH overlaps with the PUSCH in section A. When the number of available modulation symbols in region B of time slot 2 of the PUSCH transmission, after removing overhead, is greater than P, such as DMRS occupying 1 OFDM symbol, or no PTRS overhead, the PUCCH can be multiplexed with the PUSCH in time slot 2 for transmission.

[0208] Implementation method eight, such as Figure 8 As shown, the PUCCH overlaps with the PUSCH in section A. If the number of available modulation symbols in region A of time slot 1 and region B of time slot 2 after removing overhead is no greater than P (e.g., DMRS occupies 1 OFDM symbol, no PTRS overhead), then the PUSCH is not transmitted, neither region A nor region B transmits, and the PUCCH is transmitted first; or, the PUCCH is not transmitted, and the PUSCH is transmitted first.

[0209] Implementation method nine, such as Figure 9 As shown, if the PUCCH overlaps with component carriers (CC1) and CC2 in time slot 1, and single-slot PUSCH transmission is scheduled on CC1, while multi-slot PUSCH transmission is scheduled on CC2, then the PUCCH will be preferentially multiplexed onto the PUSCH of CC1 for transmission; or the PUCCH will be preferentially multiplexed onto the PUSCH of CC2 for transmission.

[0210] Implementation method ten, such as Figures 10 to 12As shown, assuming S=0, L=15, the higher-layer parameter dmrs-AdditionalPosition is configured as 'pos2', dmrs-TypeA-Position is configured as 2, and single-symbol DMRS is indicated, frequency hopping is disabled. If DMRS mapping is performed using a method where mapping type A has a higher priority than mapping type B, then time slot 1 corresponds to mapping type A, and time slot B corresponds to mapping type B. The transmission status is as follows. Figures 10 to 12 As shown. In Figure 10 In part B, DMRS is not transmitted. Figure 11 In the middle, part B transmits DMRS, in Figure 12 In slot 1, DMRS can be reduced.

[0211] Optionally, if the above-mentioned preset conditions are met between time slot 1 and time slot 2, when transmitting data in time slot 2, the channel estimation results in time slot 1 can be used; if DMRS is transmitted in time slot 2, joint channel estimation can be performed using the DMRS in time slot 1 and time slot 2.

[0212] Implementation method eleven, such as Figures 13 to 15 As shown, assuming S=13, L=15; the higher-layer parameter dmrs-AdditionalPosition is configured as 'pos2', indicating single-symbol DMRS, and frequency hopping is disabled. If mapping type B is used for DMRS mapping by default, then time slot 1 corresponds to mapping type B, time slot 2 corresponds to mapping type B, and the transmission status is as follows. Figures 13 to 15 As shown. In Figure 13 In part B, DMRS is not transmitted. Figure 14 In the middle, part B transmits DMRS, in Figure 15 In slot 1, DMRS can be reduced.

[0213] Optionally, if the above-mentioned preset conditions are met between time slot 1 and time slot 2, when transmitting data in time slot 1, the channel estimation results in time slot 2 can be used; if DMRS is transmitted in time slot 1, joint channel estimation can be performed using DMRS in time slot 1 and time slot 2.

[0214] Implementation method 12, assuming S=3, L=21. Optionally, in one embodiment, the higher-layer parameters indicate single-symbol DMRS, frequency hopping is disabled, and if mapping type B is used by default for DMRS mapping, the transmission state can be as follows: Figure 16 As shown.

[0215] Implementation method thirteen, assuming S=0, L=22. Optionally, in one embodiment, the higher-layer parameter dmrs-AdditionalPosition is configured as 'pos2', indicating single-symbol DMRS, and frequency hopping is disabled. If DMRS mapping is performed using a method where the priority of mapping type A is greater than the priority of mapping type B, the transmission state can be as follows: Figure 17 As shown.
