The base station is not limited to any specific technical terminology. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for introduction, and the specific type of base station is not limited.

[0052] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (or L-NEF), and Binding Support Function.

If the name of the core network equipment mentioned in this application embodiment changes in subsequent protocol versions (e.g., 6G), it will still be within the scope of protection of this application.

[0053] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0054] In some embodiments, taking a New Radio (NR) system as an example, rate matching refers to the fact that the number of bits after encoding may not be consistent with the number of bits that the (wireless) resources can carry. If there are more resources, which bits should be selected for transmission; if there are fewer resources, which bits should be removed.

[0055] For example: the length of the bit sequence after rate matching of the (r-th)th code block is E r The calculation method is as follows:

[0056]

[0057] Where, N L Q represents the transport layer number to which the transport block is mapped. m G represents the modulation order, G represents the total number of coded bits available for transmission corresponding to the transport block, and C′ represents the number of code blocks to be transmitted. If code block group (CBG) based transmission is not used, C′ is the number of code blocks after the transport block (TB) code block is divided.

[0058] In some embodiments, the specific process of bit selection can be represented as follows:

[0059] The sequence after rate matching is e k k = 0, 1, 2, ..., E-1, k0 is the starting position of different redundant versions:

[0060]

[0061] In some embodiments, data retransmission can be performed as follows:

[0062] Based on Low Density Parity Check (LDPC) codes, some communication systems have proposed an adaptive reliable transmission Hybrid Automatic Repeat Request (HARQ) scheme. Specifically, the transmitter first transmits a self-decoding version. If the receiver cannot decode it, the transmitter transmits another version, which may or may not be self-decoding. After soft information merging, decoding attempts continue. If the transmitted data contains a large number of system bits, it generally possesses self-decoding characteristics, meaning it can still be correctly decoded even when treated as the initial transmission. The rate matching module in the coding link selects an appropriate retransmission order and redundant versions based on the retransmission requests fed back from the HARQ control module, and then interleaves the retransmitted information bits. In this HARQ implementation based on Quasi-Cyslic Low-Density Parity-Check Codes (QC-LDPC), a ring buffer is used to select transmitted bits. The encoder encodes according to the lowest bit rate supported by the base graph (BG) (BG1 supports a minimum bit rate of 1 / 3, and BG2 supports a minimum bit rate of 1 / 5). The encoded information bits and all parity bits are then placed in the ring buffer. For each HARQ transmission, retransmitted data bits are read sequentially from the buffer according to the redundancy version number (RV), for example, RV0vRV2→RV3→RV1. The redundancy version essentially defines the starting position of each HARQ sub-packet in the buffer, for example... Figure 2 As shown.

[0063] The initial transmission version must be self-decoding capable. The starting points of each redundant version can be equally spaced or unequally spaced (non-uniform). The starting point k0 of each redundant version in the NR system is determined according to Table 1 below. Wherein, N... cb Z is the length of the circular buffer. c This is the LDPC enhancement factor.

[0064] Table 1:

[0065]

[0066] The following description, in conjunction with the accompanying drawings, details an embodiment of the encoded information receiving method, apparatus, and device provided in this application, through some specific examples and application scenarios.

[0067] Please see Figure 3 , Figure 3 This is a flowchart of an encoded information receiving method provided in an embodiment of this application, such as... Figure 3As shown, it includes the following steps:

[0068] Step 301: The first device receives first indication information, which is used to indicate relevant parameters of block coding. The block coding includes encoding N information bit groups of the information bit set using N code rates, where N is a positive integer greater than 1.

[0069] The first device mentioned above can be a terminal or a network-side device. For example, if the first device is a terminal, the information bit set is uplink data or data transmitted between terminals; if the first device is a network-side device, the information bit set is downlink data.

[0070] In some implementations, the aforementioned set of information bits may be a transport block (TB).

[0071] In some implementations, the aforementioned set of information bits is the information code block obtained after dividing the TB into code blocks. That is, code block division is performed first, and then the divided code blocks are grouped, which is equivalent to dividing each code block into N sub-code blocks.

[0072] The aforementioned first instruction information may be instruction information received by the first device from the second device, and the instruction information may be sent through one or more messages.

[0073] The number of information bit groups (i.e., the value of N) can be predetermined or determined based on transmission parameters, such as 2, 3 or 4.

[0074] In this embodiment of the application, the aforementioned information bit group may also be referred to as an information bit sequence or group.

[0075] The aforementioned N code rates can be pre-configured or indicated by the network-side device, or N code rates determined based on the code rates corresponding to the aforementioned set of information bits. The code rate corresponding to the set of information bits is a code rate, which can also be called the overall code rate.

[0076] The above N code rates correspond one-to-one with the N information bit groups, that is, each information bit group corresponds to a code rate.

[0077] The above-mentioned encoding of N information bit groups of information bit set with N code rates can be performed simultaneously by encoding the N information bit groups with N code rates respectively; that is, the N information bit groups are encoded at the same time. Alternatively, the above-mentioned encoding of the N information bit groups with N code rates can be performed in a specific order by encoding the N information bit groups with N code rates respectively, such as encoding the information bit groups with higher code rates first and encoding the information bit groups with lower code rates later.

[0078] In this embodiment of the application, the encoding method is not limited. For example, the above encoding can be Low Density Parity Check Code (LDPC) encoding, or the above encoding can be Polar encoding, etc.

[0079] The aforementioned parameters related to block coding can be parameters used during the execution of block coding. These parameters can be all or some of the parameters used during the block coding process. In the case of some parameters, the remaining parameters can be pre-configured, agreed upon by the protocol, or determined by the first device itself.

[0080] In this embodiment, since the first indication information is used to indicate the relevant parameters of the block coding, it supports encoding the N information bit groups using N code rates respectively. Compared with uniformly encoding the information bit set using a single code rate, this embodiment can improve the flexibility of information bit encoding and is beneficial to improving the transmission performance of the device.

[0081] As an optional implementation, the method further includes:

[0082] The first device sends data based on the relevant parameters of the block coding; or,

[0083] The first device decodes the received data based on the relevant parameters of the block coding;

[0084] For example: the set of bits to be transmitted is block-coded based on the relevant parameters of the block coding, and the data is transmitted based on the encoded output sequence after block coding.

[0085] As an optional implementation, the block coding includes:

[0086] The first device uses block coding when sending data; or

[0087] The packet encoding used in the data received by the first device.

[0088] The block coding used by the first device when sending data can be understood as the above-mentioned set of information bits being the set of information bits to be sent by the first device. The first device encodes the above-mentioned set of information bits using block coding and then sends the corresponding data.

[0089] The block encoding used in the data received by the first device can be understood as the encoding of the data received by the first device. For example, the second device performs block encoding on the above information bit set and sends the corresponding data to the first device.

[0090] As an optional implementation, the relevant parameters of the block coding include at least one of the following:

[0091] The validity information of the block encoding;

[0092] The number of information bit groups;

[0093] Information on the N bit rates;

[0094] The code rate information of the information bit set;

[0095] Modulation and coding scheme (MCS) information;

[0096] Information bit count;

[0097] Transmit resource information;

[0098] Redundant version indication information;

[0099] The encoding method information of the block coding.

[0100] The validity information of the above block coding is used to indicate whether block coding is used.

[0101] The number of the aforementioned information bit groups is the value of N mentioned above.

[0102] The information for the aforementioned N bitrates can be all or a portion of the aforementioned N bitrates, or the information for the aforementioned N bitrates can be information used to calculate the aforementioned N bitrates.

[0103] The bit rate information of the aforementioned information bit set can be the bit rate of the aforementioned information bit set (also known as the overall bit rate, or the bit rate of data transmission), or information used to calculate the bit rate of the aforementioned information bit set.

[0104] In some implementations, there are different code rates among the N code rates, and the average of the N code rates is equal to the code rate of the information bit set.

[0105] For example: the code rate R of each information bit group n (n=0,1,2,…,N-1) are different, and the code rate R of each packet is determined. n For n = 0, 1, 2, ..., N-1, the bit rate of each group satisfies (or ), where R is the code rate of the information bit set, that is, the overall code rate of data transmission.

[0106] In some implementations, the above N bitrates may be the same bitrate, and this application does not limit this.

[0107] In some implementations, the MCS information may include at least one of the following:

[0108] Information about the MCS table and the MCS index information of the MCS table;

[0109] The MCS table includes at least one of the following:

[0110] MCS table associated with the block code, MCS table associated with the non-block code, and MCS table associated with both the block code and the non-block code.

[0111] The information in the aforementioned MCS table can be the table name or table number, etc.

[0112] The MCS table associated with the aforementioned block coding can be understood as including relevant information about the block coding, such as relevant parameters of the block coding.

[0113] The above-mentioned non-block coding does not use block coding; it can be specifically called whole coding.

[0114] The MCS table associated with non-group coding mentioned above can be understood as containing information related to the overall coding, such as parameters related to the overall coding.

[0115] The MCS table associated with the aforementioned block coding and non-block coding can be understood as including both block coding information and overall coding information.

[0116] In some implementations, the information in the MCS table can indicate whether block coding is used. For example, when the MCS table information indicates that an MCS table associated with a block coding scheme is used, the terminal determines that the current coding scheme is a block coding scheme.

[0117] In some implementations, the MCS index information is used to indicate at least one of the following:

[0118] Modulation order;

[0119] Spectral efficiency;

[0120] The code rate among the N code rates, or the code rate of non-block coding (i.e., the code rate of the above information bit set);

[0121] The validity information of the block encoding;

[0122] The number of information bit groups.

[0123] Since the MCS index information mentioned above indicates at least one of the above, this can reduce configuration overhead.

[0124] This can be when the modulation order Qm >= X or the MCS level I. MCS When X >= Y, group coding is enabled by default, where X and Y are positive integers.

[0125] The MCS tables mentioned above can be Table 1, Table 2, or Table 3 as shown below. Tables 1, 2, and 3 indicate when block coding is enabled when Qm>=4, or for example, when Qm>=6 or Qm>=8.

[0126] Table 1:

[0127]

[0128] In Table 1 above, the target code rate Rx represents the code rate of the aforementioned set of information bits, R0 and R1 represent the code rates corresponding to the two groups of information bits, and ΔR (i) R represents the bitrate difference parameter between different information bit groups when MCS Index = i. (i) +ΔR (i) and R (i) -ΔR (i) These represent the bitrates for packet 0 and packet 1 when MCS Index = i, respectively. The MCS table above provides R... (i) • The value of 1024, and the overall bitrate or block bitrate value in the MCS table is obtained by rounding up, rounding down, rounding to the nearest integer, or retaining 1 decimal place.

[0129] Table 2:

[0130]

[0131] in, R represents the code rate corresponding to information bit group n when MCS Index = i, where R (i) R represents the target bitrate when MCS Index = i, that is, the bitrate corresponding to the above set of information bits. (i) +ΔR (i) and R (i) -ΔR (i) These represent the bit rates corresponding to information bit group 0 and information bit group 1 when MCSIndex = i, respectively. The overall bit rate R in the MCS table... (i) · 1024 or block code rate (R (i) +ΔR (i) )·1024 or (R (i) -ΔR (i) The value of 1024 is obtained by rounding up, rounding down, rounding to the nearest integer, or retaining one decimal place.

[0132] Specifically, based on the performance evaluation results of different bitrates, the bitrate must meet at least one of the following:

[0133] When N = 2, ΔR (i) The value can be any one of {0.01, 0.02, 0.03, 0.04, ..., 0.19, 0.20}.

[0134] In the MCS table (R) (i) +ΔR (i) )·1024 or (R (i) -ΔR (i) The value of 1024 is obtained by rounding up, rounding down, rounding to the nearest integer, or retaining one decimal place.

[0135] Or ΔR (i) The value of 1024 can be any one of the values ​​in {10, 10.5, 11, 11.5, ..., 199.5, 200}.

[0136] Table 3:

[0137]

[0138] Among them, in Table 3 above, R represents the code rate corresponding to information bit group n when MCS Index = i, where R (i) This represents the target bitrate when MCS Index = i. If the number of information bit groups is fixed at 2, the bitrate of the information bit groups in the table only includes... and Not included or or Overall bitrate R in the MCS table (i) · 1024 or block code rate The value is obtained by rounding up, rounding down, rounding to the nearest integer, or retaining one decimal place.

[0139] In Tables 1, 2, and 3 above, the MCS index information can directly indicate the modulation order, spectral efficiency, and the code rate among the N code rates. It can also indirectly indicate the code rate of non-block coding, the validity information of the block coding, and the number of information bit groups. For example, indicating two block code rates means that the block coding is valid, the number of information bit groups is 2, and the code rate of non-block coding can be calculated from the block code rates.

[0140] In some implementations, the number of information bits is used to indicate at least one of the following:

[0141] The number of information bits in the N information bit groups (which can be called the group size TB);

[0142] The number of information bits in the information bit set (which can be referred to as the overall TBsize).

[0143] By increasing the number of information bits in the aforementioned N information bit groups or the number of information bits in the information bit set, the complexity of the first device performing block encoding or the complexity of the first device performing decoding can be reduced.

[0144] In some implementations, the transmission resource information is used to indicate: resource allocation information for transmitting the information bit set, the resource allocation information including at least one of the following:

[0145] Number of resource units, number of transport layers.

[0146] The number of resource units mentioned above may include at least one of the following:

[0147] The number of allocated OFDM symbols, the number of subcarriers within a single Physical Resource Block (PRB) used to carry the current TB of data, the number of allocated PRBs, and the number of resource elements (REs) within a single PRB used to carry the Demodulation Reference Signal (DMRS).

[0148] The aforementioned transmission resource information enables the first device to transmit signals based on the resources indicated by the transmission resource information, thereby improving the reliability of transmission.

[0149] In some implementations, the aforementioned transmission resource information can also be used to implicitly indicate other parameters of block coding. For example, there may be a mapping relationship between the number of resource units or transmission layers and the N code rates, the value of N, or whether block coding is used, thereby determining the N code rates, the value of N, or whether block coding is used based on the mapping relationship.

[0150] The encoding scheme information of the above block coding is used to indicate the specific block coding. For example, the encoding scheme information is used to indicate at least one of the following:

[0151] The N information bit groups are encoded using the same encoder, or the N information bit groups are encoded using different encoders;

[0152] The N information bit groups can be encoded using the same encoding type, or the N information bit groups can be encoded using different encoding types.

[0153] The above-mentioned encoding types include LDPC encoding, Polar encoding, RM (Reed-Muller) encoding, and convolutional codes.

[0154] In this embodiment, when the same encoder is used to encode the N information bit groups, the same encoder can be reused for multiple information bit groups, thereby saving resource overhead.

[0155] In this embodiment, the complexity of encoding multiple information bit groups can be reduced by using the same encoding type to encode the N information bit groups.

[0156] In some implementations, when the same encoder is used to encode the N information bit groups, the first parameter for encoding the N information bit groups is the same, and the first parameter includes at least one of the following: base graph (BG), boost factor, generator matrix, parity check matrix, input code block length, encoder output code block length, and master code rate.

[0157] Alternatively, when different encoders are used to encode the N information bit groups, the second parameter for encoding the N information bit groups is different. The second parameter includes at least one of the following: BG, boost factor, generator matrix, parity check matrix, input code block length, encoder output code block length, and master code rate.

[0158] Since the first parameter is the same, this reduces the complexity of encoding multiple information bit groups.

[0159] The second parameter is different; it allows each information bit group to use its own corresponding parameters during the encoding process, thereby improving encoding performance.

[0160] In addition, the first parameter and the second parameter mentioned above can be the same parameter, that is, the first parameter and the second parameter include the same parameter. In some embodiments, the first parameter and the second parameter may be partially different or completely different. For example, the first parameter includes BG, boost factor, generator matrix and parity check matrix, and the second parameter includes BG, boost factor, encoder input code block length, encoder output code block length and master code rate.

[0161] The aforementioned redundant version indication information is used to indicate information related to redundant versions. For example, the aforementioned redundant version indication information includes at least one of the following:

[0162] New data transmission indication;

[0163] Redundant version index;

[0164] Index of the retransmitted information bit group;

[0165] The weighting information of the retransmitted information bit group.

[0166] The aforementioned new data transmission indicator is used to indicate whether the currently transmitted data is newly transmitted data or retransmitted data.

[0167] The index of the retransmitted information bit group mentioned above is used to indicate which information bit groups' corresponding encoded output bit sequences are used to generate the redundant version signal during retransmission. This parameter can also be omitted, in which case the redundant version signal is generated based on the encoded output bit sequences corresponding to all information bit groups by default.

[0168] By using the index of the retransmitted information bit group mentioned above, retransmission can be performed flexibly, which helps to save transmission resources, such as when it is not necessary to retransmit the entire information bit group.

[0169] The weight information of the retransmission information bit group mentioned above can indicate the proportion of data corresponding to different packets in the redundant version data during retransmission. It can be reflected as the number of retransmissions of a certain packet in the current redundant version (i.e., the number of times the corresponding version bit sequence is repeatedly selected during rate matching), or the length of the rate matching output sequence.

[0170] The weighting information of the retransmission information bit groups mentioned above allows for flexible data retransmission, which helps save transmission resources, such as allowing only a portion of the bit groups to be retransmitted.

[0171] In some implementations, when the first information bit group among the N information bit groups is determined based on the redundancy version indication information, the retransmission bits of the first code block of the first information bit group include one of the following:

[0172] Based on the starting position of the redundant version, select sequentially from the circular buffer corresponding to the first code block a length of N·E. r The bit sequence;

[0173] Based on the starting position of the redundant version, repeatedly select a length of E from the circular buffer corresponding to the first code block. r The N·E obtained from the bit sequence r Bit sequence;

[0174] Based on the starting position of the redundant version, select sequentially from the circular buffer corresponding to the first code block a length of E. r The bit sequence;

[0175] Among them, E r The length of the first block code.

[0176] In the above implementation, based on the starting position of the redundant version, sequentially select from the circular buffer corresponding to the first code block a length of N·E. rThe bit sequence, or repeatedly selected from the circular buffer corresponding to the first code block according to the starting position of the redundant version, is of length E. r The N·E obtained from the bit sequence r Bit sequence, due to the selection of N·E r Bit sequences can be used to transmit more repeating bit sequences, thereby improving the reliability of transmission.

[0177] The first code block is code block r. The initial transmission bit selection and retransmission bit selection are illustrated as follows: Figure 4 As shown, during the initial transmission, two information bit groups are selected as code blocks r. When selecting for retransmission, the length of information bit group 1 is N·E. r The bit sequence.

[0178] The above method selects, based on the starting position of the redundant version, sequentially from the circular buffer corresponding to the first code block, a length of E. r The bit sequence allows for the selection of only E. r Bit sequence, i.e., only E is transmitted r This reduces the amount of data transmitted by one bit.

[0179] It should be noted that, in the embodiments of this application, some of the parameters related to the above-mentioned group coding can be explicitly indicated, some parameters can be implicitly indicated, such as being indirectly indicated by other parameters, or some parameters can be pre-configured or agreed upon in advance.

[0180] As an optional implementation, the number of information bits in the N information bit groups is indicated by at least one of the following:

[0181] The validity information of the block encoding;

[0182] The number of information bit groups;

[0183] Information on the N bit rates;

[0184] MCS information;

[0185] Transmit resource information.

[0186] The number of information bits in the aforementioned N information bit groups can be understood as an implicit indication of the number of information bits in the aforementioned N information bit groups, as indicated by at least one of the above indicators. For example, when the validity information of the block coding indicates that the block coding is valid, the number of information bits in the N information bit groups is a predefined number of information bits; another example is that the number of information bit groups is mapped to the number of information bits in the N information bit groups, and the number of information bits in the N information bit groups can be determined based on this mapping relationship; another example is that the MCS table indicated by the MCS information includes relevant information about the number of information bits in the N information bit groups, and the number of information bits in the N information bit groups can be calculated based on this relevant information; another example is that the number of transmission layers indicated by the aforementioned transmission resource information is mapped to the number of information bits in the N information bit groups, and the number of information bits in the N information bit groups can be determined based on this mapping relationship.

[0187] Through the above implementation method, the number of information bits in the above N information bit groups can be implicitly defined, thereby saving configuration overhead.

[0188] As an optional implementation, the number of information bits in the information bit set is indicated by at least one of the following:

[0189] The validity information of the block encoding;

[0190] The number of information bit groups;

[0191] Information on the N bit rates;

[0192] MCS information;

[0193] Transmit resource information.

[0194] The number of information bits in the aforementioned information bit set can be understood as an implicit indication of the number of information bits in the aforementioned information bit set, for example: when the validity information of the block coding indicates that the block coding is invalid, the number of information bits in the information bit set is a predefined number of information bits; another example: the number of information bit groups is mapped to the number of information bits in the information bit set, and the number of information bits in the information bit set can be determined based on this mapping relationship; another example: the MCS table indicated by the MCS information includes relevant information about the number of information bits in the information bit set, and the number of information bits in the information bit set can be calculated based on this relevant information; another example: the number of transmission layers indicated by the aforementioned transmission resource information is mapped to the number of information bits in the information bit set, and the number of information bits in the information bit set can be determined based on this mapping relationship.

[0195] Through the above implementation method, the number of information bits in the above information bit set can be implicitly defined, thereby saving configuration overhead.

[0196] As an optional implementation, the encoding method information of the block coding is indicated by at least one of the following:

[0197] The information of the N code rates and the information bit count.

[0198] The information on the N bit rates and the number of information bits can be implicitly information indicating the encoding method of the block coding. For example, when the difference in bit rate or the difference in TBsize between different information bit groups relative to a specific information bit group (e.g., the information bit group with the highest bit rate) does not exceed a preset threshold, the different information bit groups use the same encoder for encoding; when the difference in bit rate or the difference in TBsize between different information bit groups relative to a specific information bit group (e.g., the information bit group with the highest bit rate) is not lower than (or exceeds) a preset threshold, the different information bit groups use different encoders for encoding or different encoding types for encoding.

[0199] In this embodiment, configuration overhead can be saved by using information on N code rates and the number of information bits to indicate the encoding method information of the block encoding.

[0200] As an optional implementation, in the case of retransmission of multiple information bit groups among the N information bit groups, the redundant version signal transmitted during the retransmission process is preferentially generated based on the encoded output bit set corresponding to the information bit group with the lower bit rate.

[0201] In the aforementioned retransmission process, the redundant version signal is generated primarily based on the encoded output bit set corresponding to the low-bit-rate information bit group. This can be understood as first generating the redundant version signal based on the bit sequence corresponding to the low-bit-rate information bit group, and then generating the redundant version signal based on the bit sequence corresponding to the high-bit-rate information bit group. For example, if the bit rate corresponding to information bit group 0 is higher than that corresponding to information bit group 1, and the RV transmission order is {0,2,1,3}, the initial RV0 signal is generated and sent based on the encoded output bit sets corresponding to information bit groups 0 and 1. During the first retransmission, RV2 is generated and sent based on the encoded output bit set corresponding to information bit group 1. During the second retransmission, RV2 is generated and sent based on the encoded output bit set corresponding to group 0. During the third retransmission, RV1 is generated and sent based on the encoded output bit set corresponding to group 1. During the fourth retransmission, RV1 is generated and sent based on the encoded output bit set corresponding to group 0. During the fifth retransmission, RV3 is generated and sent based on the encoded output bit set corresponding to group 1. During the sixth retransmission, RV3 is generated and sent based on the encoded output bit set corresponding to group 0, and so on.

[0202] Since the data transmission performance of low-bit-rate information bit groups is relatively poor compared to that of high-bit-rate information bit groups, the redundant version signal is generated first based on the bit sequence corresponding to the low-bit-rate information bit group. This is to prioritize the retransmission of the bit sequence of the information bit group with high error rate, thereby improving the overall data transmission performance.

[0203] As an optional implementation, the N bit rates are determined based on at least one of the following:

[0204] Protocol stipulations, MCS table, MCS level, preset rules, signaling indications, and the code rate of the information bit set.

[0205] The MCS table mentioned above can include the above N bitrates, which avoids introducing additional information and saves configuration overhead. The above MCS table can be found in Tables 1, 2 and 3 above.

[0206] In some implementations, based on performance evaluation results, the bitrate satisfies at least one of the following:

[0207] When N=2, or The value can be any one of {0.01, 0.02, 0.03, 0.04, ..., 0.19, 0.20}.

[0208] Among them, information bit group 0 is the high code rate group, and information bit group 1 is the low code rate group;

[0209] MCS table The value is based on The result is obtained by rounding up, rounding down, rounding to the nearest integer, or retaining one decimal place.

[0210] Or or The value can be any one of {10, 10.5, 11, 11.5, ..., 199.5, 200}.

[0211] Alternatively, the code rate of different information bit groups is determined based on the sub-channel capacity corresponding to different bits in QAM modulation, for example:

[0212] The total channel capacity corresponding to the modulation symbols is: I = R·Q m Where I represents the modulation order Q m When the code rate is R, the total channel capacity (or spectral efficiency, which can be determined from the MCS table based on the MCS level) corresponding to the modulation symbols, where R represents the overall code rate of the information bit set, and Q... m Q is the modulation order. m =M, where M is the number of bits in the modulation symbol.

[0213] Given the total channel capacity of the modulation symbols, the first device can determine the channel capacity of the sub-channel corresponding to the M bits based on the total channel capacity of the modulation symbols. For example, it can determine the channel capacity of the sub-channel corresponding to the M bits based on the mapping relationship between the total channel capacity and the sub-channel capacity.

[0214] The determination of the channel capacity of the sub-channel corresponding to the M bits based on the total channel capacity of the modulation symbols can include:

[0215] Based on the total channel capacity of the modulation symbols and the preset channel capacity mapping relationship, the channel capacity of the sub-channels corresponding to the M bits is determined;

[0216] The channel capacity mapping relationship is the mapping relationship between the total channel capacity of the modulation symbol and the channel capacity of the sub-channel corresponding to each bit of the modulation symbol.

[0217] The aforementioned channel capacity mapping relationship can be a mapping relationship between the total channel capacity of the modulation symbol and the channel capacity of the sub-channel corresponding to each bit of the modulation symbol. For example, the aforementioned channel capacity mapping relationship can be a channel capacity table, which can be shown in Tables 4 and 5. Given a total channel capacity, the channel capacity of each sub-channel can be obtained. For example, for 16-QAM, when the calculated total channel capacity is 3 bits per second, the channel capacity of sub-channel 1 and sub-channel 3 is 0.841 bits per symbol, and the channel capacity of sub-channel 2 and sub-channel 4 is 0.679 bits per symbol. Understandably, since the data in the channel capacity table is discontinuous, once the total channel capacity is calculated, the channel capacity of each sub-channel can be queried based on the total channel capacity in the channel capacity table that is closest to the calculated total channel capacity. Alternatively, the smallest total channel capacity in the channel capacity table that is not less than the calculated total channel capacity value can be selected. For example, if the calculated total channel capacity is 3 bits / symbol, and the total channel capacity in the channel capacity table that is closest to this value is 3.041374 bits / symbol, then the channel capacity of each sub-channel can be queried based on 3.041374.

[0223]

[0224] In some implementations, it is assumed that the size of the modulation constellation point set X is |X| = 2. M Using Gray mapping, let f(·) denote the mapping rule, then the modulation symbol is represented as: Each modulation symbol contains M bits, which are called constellation point labels. Let b j (x) represents the j-th bit of the label in the modulation symbol, where 1 ≤ j ≤ M. This modulation symbol channel can be considered as consisting of M parallel equivalent subchannels, b j (x) represents the input of each equivalent subchannel. Let Let represent the set of constellation points whose index is q at the j-th position, i.e.:

[0225]

[0226] Where q∈{0,1}, the capacity of the j-th subchannel can be calculated by the following formula:

[0227]

[0228] Where Y represents the set of channel output symbols, P Y|X (·) represents the channel transition probability. Represents the total channel probability, used for normalization. This represents the transition probability at position j.

[0229] Specifically, in the Monte Carlo simulation process, the channel capacity of each sub-channel can be calculated using the above formula, and then the simulation curves of the capacity of each sub-channel can be plotted. The total channel capacity is the sum of the channel capacities of all the sub-channels. Having obtained the simulation curves of the total channel capacity and the capacities of each sub-channel, the channel capacity table can be generated based on these curves.

[0230] It can be seen that when the modulation order is Q m At that time, the sub-channel capacity relationship is as follows:

[0231] Sub-channel The data corresponds to the I-channel data modulated by QAM, sub-channel The data corresponds to the Q-channel data of QAM modulation.

[0232] After determining the sub-channel capacity, the block code rate is determined based on the correlation between different information bit groups and the sub-channel, including:

[0233] When N is an integer associated with the modulation order, i.e. Each information bit group is associated with two sub-channels, and the two sub-channels have the same capacity. High-rate information bit groups are associated with high-capacity sub-channels, and low-rate information bit groups are associated with low-capacity sub-channels. This can include:

[0234] For 16QAM, the number of information bit groups N = 2: the sub-channels associated with information bit group 0 are sub-channels 1 and 3, and the sub-channels associated with group 1 are sub-channels 2 and 4;

[0235] For 64QAM, the number of information bit groups N = 3: the sub-channels associated with information bit group 0 are sub-channels 1 and 4, the sub-channels associated with information bit group 1 are sub-channels 2 and 5, and the sub-channels associated with information bit group 2 are sub-channels 3 and 6.

[0236] For 256QAM, the number of packets is N=4: the sub-channels associated with information bit group 0 are sub-channels 1 and 5, the sub-channels associated with information bit group 1 are sub-channels 2 and 6, the sub-channels associated with information bit group 2 are sub-channels 3 and 7, and the sub-channels associated with information bit group 3 are sub-channels 4 and 8.

[0237] For 1024QAM, when the number of packets is N=5: the sub-channels associated with information bit group 0 are sub-channels 1 and 6, the sub-channels associated with information bit group 1 are sub-channels 2 and 7, the sub-channels associated with information bit group 2 are sub-channels 3 and 8, the sub-channels associated with information bit group 3 are sub-channels 4 and 9, and the sub-channels associated with information bit group 4 are sub-channels 5 and 10.

[0238] Each information bit group is associated with two sub-channels, and the two sub-channels have the same capacity. The code rate of group n is calculated as follows: J n Let I represent the set of subchannel indices associated with information bit group n, where I represents the total channel capacity, N is the number of information bit groups, and R is the overall data transmission rate.

[0239] When N is a fixed integer, i.e., N=2, each information bit group is associated with a sub-channel. One, high-rate information bit group and higher capacity Subchannel correlation, low-rate information bit groups and lower capacity Subchannel associations can include:

[0240] For 16QAM, the sub-channels associated with information bit group 0 are sub-channels 1 and 3, and the sub-channels associated with information bit group 1 are sub-channels 2 and 4.

[0241] For 64QAM, the sub-channels associated with information bit group 0 are sub-channels 1, 4, and 2, and the sub-channels associated with information bit group 1 are sub-channels 5, 3, and 6.

[0242] For 256QAM, the sub-channels associated with information bit group 0 are sub-channels 1, 5, 2, and 6, and the sub-channels associated with information bit group 1 are sub-channels 3, 7, 4, and 8.

[0243] For 1024QAM, the sub-channels associated with information bit group 0 are sub-channels 1, 6, 2, 7, and 3, and the sub-channels associated with information bit group 1 are sub-channels 8, 4, 9, 5, and 10.

[0244] Each information bit group is associated with a sub-channel. The code rate of information bit group n is calculated as follows:

[0245] Jn Let I represent the set of subchannel indices associated with information bit group n, where I represents the total channel capacity, N is the number of information bit groups, and R is the overall data transmission rate.

[0246] In some implementations, the MCS level can be mapped to the N bitrates, thereby determining the corresponding bitrate based on the mapping.

[0247] In some implementations, when the MCS level is in an MCS table, the MCS table includes indication information of the MCS level, such as the MCS index, and also includes the N bitrates.

[0248] By determining the above N bitrates through the MCS level, configuration overhead can be reduced.

[0249] The aforementioned preset rules can be pre-configured rules for determining the aforementioned N code rates. For example, given the code rate difference correlation parameter ΔR between information bit groups, when the number of groups is 2, the code rates corresponding to the 2 information bit groups are R-ΔR and R+ΔR, respectively; when the number of groups is 3, the code rates of the 3 information bit groups are R-ΔR, R, and R+ΔR, respectively; when the number of groups is 4, the code rates of the 4 information bit groups are R-2ΔR, R-ΔR, R+ΔR, and R+2ΔR, respectively; when the number of groups is 5, the code rates of the 5 information bit groups are R-2ΔR, R-ΔR, R, R+ΔR, and R+2ΔR, respectively, where R is the code rate of the information bit set, and ΔR is associated with at least one of the following: the MCS table used, the MCS level, and the Channel Quality Indicator (CQI).

[0250] The aforementioned signaling indications can be explicit or implicit, specifically indicated by relevant parameters in higher-level signaling or by relevant parameters in layer-1 signaling.

[0251] By using signaling indication, N code rates can be dynamically and flexibly indicated, making the encoding more flexible.

[0252] The N code rates of the aforementioned information bit set can be determined by adding a preset value to a portion of the N code rates based on the code rates of the information bit set, and subtracting a preset value from another portion of the N code rates based on the code rates of the information bit set, to obtain the aforementioned N code rates.

[0253] Determining the N code rates using the code rates of the aforementioned information bit set can save configuration overhead.

[0260] ACK / NACK information in the information bit group;

[0261] Information about the suggested retransmission bit group;

[0262] The recommended weighting of retransmission bit groups.

[0263] The ACK / NACK information above is used to indicate ACK or NACK, which can indicate whether the decoding was correct or incorrect.

[0264] The ACK / NACK information of the aforementioned information bit group can be the ACK / NACK information of at least one information bit group. Specifically, the ACK / NACK information of one information bit group can be the overall decoding correctness or error information corresponding to different information bit groups, and the ACK / NACK information of multiple information bit groups can be the decoding correctness or error information of multiple code blocks corresponding to different information bit groups. For example, the ACK / NACK information of the aforementioned information bit group can be used to indicate at least one of the following:

[0265] The overall decoding of the N information bit groups is either correct or incorrect;

[0266] The information of the correctly decoded information bit group among the N information bit groups;

[0267] Information about the information bit group with decoding errors in the N information bit groups.

[0268] The information about the suggested retransmission bit groups can be indicated by a bitmap, suggesting which bit groups correspond to the encoded data to be retransmitted.

[0269] The retransmission packet weighting information suggested above can be found in the retransmission information bit group weighting information described in the above embodiments, and will not be repeated here.

[0270] The feedback information mentioned above enables data retransmission at multiple granularities, which helps save transmission resources.

[0271] The following example illustrates block coding. Figure 5 As shown, it includes the following steps:

[0272] Step 501: The first device groups the information bit set into N information bit groups, where N is an integer greater than 1;

[0390] It should be noted that this embodiment is as a comparison with... Figure 3 The implementation method of the second device corresponding to the illustrated embodiment can be found in the following examples. Figure 3 To avoid repetition, the relevant descriptions of the embodiments shown will not be repeated in this embodiment.

[0391] The following uses a first device as the terminal and a second device as the network-side device as an example to illustrate the method provided in the embodiments of this application through multiple examples:

[0392] Example 1:

[0393] This embodiment provides a method for indicating encoding-related parameters when data transmission uses a packet-based encoding scheme, including:

[0394] The network-side device (i.e., the second device mentioned above) sends first indication information to the terminal (i.e., the first device mentioned above) to indicate parameters related to packet coding. The first indication information includes at least one of the following:

[0395] Block coding validity information, i.e., indication information on whether block coding is used;

[0396] Information on the number of information bit groups;

[0397] Code rate information for information bit groups;

[0398] Overall bitrate information;

[0399] MCS information;

[0400] TBsize information, i.e., the number of information bits;

[0401] Transmit resource information;

[0402] Redundant version indication information;

[0403] Group coding method information.

[0404] In some implementations, the MCS information includes at least one of the following:

[0405] MCS table information and MCS index information associated with the MCS table;

[0406] The MCS table includes at least one of the following:

[0407] MCS table associated with the block coding scheme;

[0408] The MCS table associated with the overall coding scheme (i.e., the scheme without group coding);

[0409] MCS tables associated with block coding and overall coding schemes.

[0410] Each MCS index is associated with at least one of the following:

[0411] Modulation order;

[0412] Code rate, including overall coding code rate or block coding code rate, where the overall coding code rate is equal to the sum of the block coding code rates;

[0413] Spectral efficiency.

[0414] In some implementations, network-side devices can use MCS information to indicate whether to use at least one of the following: packet coding, number of packets, and packet code rate. On the one hand, the terminal can determine whether to use packet coding based on MCS table information. For example, when the MCS table information indicates the use of an MCS table associated with a packet coding scheme, the terminal determines that the current coding scheme is a packet coding scheme. On the other hand, the terminal can determine the number of packets or packet code rate based on MCS index information. For example, the number of packets or packet code rate can be determined by looking up the corresponding MCS table based on the MCS index information.

[0415] In some implementations, the TBsize information mentioned above includes at least one of the following:

[0416] The total TBsize is the number of information bits in the aforementioned set of information bits.

[0417] Group TBsize is the number of information bits in the above N information bit groups.

[0418] Wherein, the overall TBsize is equal to the sum of the TBsizes of each group.

[0419] In some implementations, the transmission resource information is used to determine the resource allocation for the transmission of the current TB (i.e., the aforementioned set of information bits), including at least one of the following:

[0420] The number of resource units includes at least one of the following: the number of allocated OFDM symbols, the number of subcarriers within a single PRB used to carry the current TB data, the number of allocated PRBs, and the number of REs within a single PRB used to carry DMRS.

[0421] Number of transport layers.

[0422] In some implementations, the network-side device can indicate the aforementioned TBsize information through at least one of the following: transmission resource information, MCS information, packet coding validity information, number of information bit groups, and code rate information of the information bit groups. That is, the terminal can calculate the packet TBsize or the overall TBsize based on at least one of the following: transmission resource information, MCS information, number of information bit groups, and code rate information of the information bit groups. The number of information bit groups and the code rate information of the information bit groups can be determined based on the MCS information.

[0423] In some implementations, the above-mentioned block coding scheme information includes at least one of the following: different information bit groups are encoded using the same encoder, different information bit groups are encoded using different encoders, and different information bit groups use different coding types (e.g., LDPC coding, Polar coding, RM coding, convolutional codes, etc.).

[0424] The use of the same encoder to encode different groups of information bits includes at least one of the following:

[0425] When LDPC encoding the information bit sets corresponding to different information bit groups, the same LDPC encoding BG and boosting factor Z are used;

[0426] The same parity check matrix H is used when LDPC encoding the information bit sets corresponding to different information bit groups;

[0427] Different information bit groups correspond to the same encoded input code block length;

[0428] The encoder output code block length is the same for different information bit groups;

[0429] The mother code rate is the same for different information bit groups.

[0430] The use of the same encoder to encode different groups of information bits includes at least one of the following:

[0431] When LDPC encoding the information bit sets corresponding to different information bit groups, different LDPC encoding BG or different boosting factors Z are used;

[0432] Different parity-check matrices H are used when LDPC encoding the information bit sets corresponding to different information bit groups;

[0433] Different information bit groups correspond to different encoded input code block lengths;

[0434] The encoder output code block lengths are different for different information bit groups;

[0435] Different information bit groups correspond to different mother code rates.

[0436] In some implementations, the network-side device can indicate the encoding method information by indicating the bit rate information or TBsize information of the information bit group. That is, the terminal determines the encoding method to be used based on the bit rate of the information bit group or the TBsize of the group. This can be because when the difference in bit rate of different information bit groups relative to a specific group (e.g., the group with the highest bit rate) or the difference in TBsize of the information bit groups does not exceed a preset threshold, the different information bit groups use the same encoder for encoding; or when the difference in bit rate of different information bit groups relative to a specific information bit group (e.g., the information bit group with the highest bit rate) or the difference in TBsize of the information bit groups is not lower than (or exceeds) a preset threshold, the different information bit groups use different encoders for encoding or different encoding types for encoding.

[0437] The code rate of the information bit group can also be determined by the terminal based on the MCS information, that is, the network-side device can indicate the encoding method information by indicating the MCS information.

[0438] The information bit group TBsize can also be determined by the terminal based on at least one of the following: transmission resource information, MCS information, packet coding validity information, number of information bit groups, and code rate information of information bit groups. That is, the network-side device can indicate the coding method information by indicating at least one of the above information.

[0439] In some implementations, the redundant version indication information includes at least one of the following:

[0440] New data transmission indicator, which indicates whether the data currently being transmitted is newly transmitted data or retransmitted data;

[0441] Redundant version index;

[0442] The retransmission packet index information indicates which packets' coded output bit sequences are used to generate the redundant version signal during retransmission. This parameter can also be omitted, in which case the redundant version signal is generated based on the coded output bit sequences of all packets.

[0443] The retransmission packet weight information indicates the proportion of data corresponding to different packets in the redundant version of data during retransmission. It can be reflected as the number of retransmissions of a certain packet in the current redundant version (i.e., the number of times the corresponding bit sequence is repeatedly selected during rate matching), or the length of the rate matching output sequence.

[0444] In some implementations, the first indication information indicates the encoding scheme and encoding parameters used by the network-side device when sending downlink data to the terminal, and the terminal receives and decodes the downlink data according to the first indication information; or, the first indication information indicates the encoding scheme and encoding parameters used by the terminal when sending uplink data to the network-side device, and the terminal encodes and sends the uplink data according to the first indication information.

[0445] In some implementations, the items in the first indication information described above may be sent via the same signaling or via different signaling. For example, the MCS table information may be sent via higher-layer signaling (such as Radio Resource Control (RRC) signaling), and the MCS index information and packet coding validity information may be sent via layer-1 signaling (such as Downlink Control Information (DCI) signaling).

[0446] In some implementations, before the network-side device sends the first indication information to the terminal, it further includes receiving first feedback information sent by the terminal device, wherein the first feedback information includes at least one of the following:

[0447] ACK / NACK information associated with TB;

[0448] ACK / NACK information associated with at least one CB;

[0449] The ACK / NACK information associated with at least one packet can be the overall decoding correct or incorrect information corresponding to different packets, or the decoding correct or incorrect information of multiple code blocks corresponding to different packets.

[0450] The packet index information that suggests retransmission, for example: using a bitmap to indicate which packets' corresponding encoded data should be retransmitted;

[0451] Recommended retransmission packet weighting information.

[0452] Example 2:

[0453] This embodiment mainly describes whether block coding is used, the number of information bit groups, the code rate of the information bit groups, and the encoding method through MCS information indication.

[0454] This embodiment provides a detailed explanation of how the terminal determines whether to use block coding, the number of information bit groups, or the code rate of the information bit groups based on the MCS information indicated by the network-side device.

[0455] The number of information bit groups can be fixed at 2 for all modulation orders, i.e., divided into high-rate group information bit sets and low-rate group information bit sets. In this case, for different modulation orders, two circular buffers are used to store the encoded output bit sets corresponding to the high-rate group and the low-rate group respectively, and it is not necessary to indicate the number of information bit groups. Alternatively, the number of information bit groups can vary for different modulation orders. For example, for 16QAM, the number of information bit groups is 2; for 64QAM, the number of information bit groups is 2 or 3; for 256QAM, the number of groups is 2 or 4; and for 1024QAM, the number of information bit groups is 2 or 5. In this case, the number of information bit groups may differ for different modulation orders, and it is necessary to indicate the number of groups, or the terminal determines the number of groups based on the MCS information.

[0456] Among them, the code rate R of each information bit group n n = 0, 1, 2, ..., N-1 satisfies (or R represents the overall data transmission rate. The code rate information for each information bit group in the first indication information can be the encoding code rate of each information bit group, or the code rate difference correlation parameter ΔR between information bit groups. For 2 information bit groups, the code rates for 2 groups are R-ΔR, R+ΔR; for 3 information bit groups, the code rates for 3 groups are R-ΔR, R, R+ΔR; for 4 information bit groups, the code rates for 4 groups are R-2ΔR, R-ΔR, R+ΔR, R+2ΔR; and for 5 information bit groups, the code rates for 5 groups are R-2ΔR, R-ΔR, R, R+ΔR, R+2ΔR. After determining the overall encoding rate, the terminal can determine the code rate of different information bit groups based on the number of information bit groups and the code rate difference correlation parameter.

[0457] The MCS tables associated with the aforementioned block coding schemes refer to MCS tables that contain code rate information for information bit groups, such as Table 6 below. Among them, SE represents the code rate corresponding to information bit group n when MCS Index = i. (i) This represents the spectral efficiency when MCSIndex = i. If the number of blocks is fixed at 2, the code rate of the information bit blocks in the table only includes... and Not included or or Block code rate in MCS table The value is obtained by rounding up, rounding down, rounding to the nearest integer, or retaining one decimal place.

[0458] Table 6:

[0459]

[0460] The MCS table associated with the overall coding scheme mentioned above refers to the MCS table containing overall bitrate information, as shown in Table 7 below. Wherein, R... (i) SE represents the overall bitrate when MCS Index = i. (i) This represents the spectral efficiency when MCS Index = i. The overall code rate R in the MCS table is... (i) The value 1024 is obtained by rounding up, rounding down, rounding to the nearest integer, or retaining one decimal place.

[0461] Table 7:

[0462]

[0463] The MCS table associated with the above-mentioned block coding scheme and overall coding scheme refers to the MCS table containing block code rate information and overall code rate information, as shown in Table 1, Table 2 or Table 3 above, which will not be elaborated here.

[0464] Network-side devices can indicate the specific MCS table to be used through the MCS description in higher-layer signaling. If the available MCS tables include MCS tables associated with packet coding schemes and MCS tables associated with overall coding schemes, then when the network-side device indicates the use of an MCS table associated with a packet coding scheme, it means that a packet coding scheme is used; when the network-side device indicates the use of an MCS table associated with an overall coding scheme, it means that a packet coding scheme is not used.

[0465] If the available MCS table includes MCS tables associated with both the packet coding scheme and the overall coding scheme, meaning that a unified MCS table is used regardless of whether a packet coding scheme is adopted, then the network-side device indicates whether to adopt the packet coding scheme through the packet coding validity information.

[0466] It should be noted that there may be multiple MCS tables associated with the block coding scheme, the overall coding scheme, or both, to adapt to different data transmission scenarios.

[0467] After determining the MCS table to be used, the network-side equipment instructs the terminal on the MCS index I via Layer 1 control signaling. MCS The terminal is based on I MCS The modulation order Q is determined by looking up the corresponding MCS table. m Overall bitrate R (i) Number of blocks, block bitrate At least one of the following: spectral efficiency.

[0468] In some implementations, the block code rate is determined. Then, assuming Terminal equipment can be based on Whether the preset threshold ξ is exceeded determines the encoding method for group 1, 2, ..., N-1, i.e., if... Group n and group 0 use the same encoder; if Packet n and packet 0 use different encoders or different encoding methods. Alternatively, regardless of the packet bitrate, different packets can use the same encoder and the same encoding method by default. In this case, the network-side device does not need to indicate the encoding method information, and the terminal does not need to determine the encoding method based on the packet bitrate.

[0469] Example 3:

[0470] This implementation mainly describes how TBsize information is indicated by transmitting resource information, the number of information bit groups, and the bit rate information of the information bit groups.

[0471] This embodiment provides a detailed explanation of how the terminal determines the TBsize information based on the transmission resource information, the number of information bit groups, and the code rate information of the information bit groups indicated by the network-side device. The packet coding validity information, the number of information bit groups, or the code rate information of the information bit groups can be indicated through MCS information. As described in Embodiment 2, the terminal determines whether to perform packet coding, the number of information bit groups, and the code rate information of the information bit groups based on the MCS information, and then determines the TBsize information based on the transmission resource information, the number of information bit groups, and the code rate information of the information bit groups.

[0472] Wherein, the overall TBsize is the total number of information bits transmitted, and the group TBsize is the number of information bits corresponding to different information bit groups. When group coding is used, the overall TBsize is equal to the sum of the group TBsizes.

[0473] When the terminal determines not to use block coding based on MCS information or block coding validity information, the terminal determines the overall code rate information and modulation order information based on the MCS information, and determines the overall TBsize information based on the transmission resource information, overall code rate information, and modulation order information. Specifically, it can be, for example:

[0474] according to Calculate the number of REs in a PRB for PDSCH, where Indicates the number of subcarriers within a single RB; This represents the number of scheduling symbols for PDSCH within a slot; This represents the number of REs occupied by DMRS within each PRB in the Physical downlink shared channel (PDSCH) scheduling symbol. Note that the calculation of the number of DMRS REs is also related to whether the data is multiplexed with PDSCH in the DMRS code division multiplexing (CDM) group. The value of xOverhead is determined by the higher-layer parameter xOverhead, which can be configured to 0, 6, 12, or 18. When xOverhead is not configured, the higher-layer parameter N_PRB_oh is configured to 0. Furthermore, when the PDCCH scheduling PDSCH is scrambled by the System Information Radio Network Temporary Identifier (SI-RNTI), Random Access Radio Network Temporary Identifier (RA-RNTI), MsgB Radio Network Temporary Identifier (MsgB-RNTI), or Paging Radio Network Temporary Identity (P-RNTI), It is also configured to 0.

[0475] In some implementations, N can be used as a reference. RE =min(156,N') RE )·n PRB Determine the total number of REs in the PDSCH schedule, where nPRB is the number of scheduling PRBs in the PDSCH.

[0476] In some implementations, N can be used as a reference. info =N RE ·R·Q m • υ Calculate the information bit value Ninfo (this value is an intermediate quantity, and the final number of transmitted information bits depends on TBsize), where R represents the target code rate, Qm represents the modulation order, and v represents the transmission layer.

[0477] right Quantize the value, if Then through Quantification is performed and TBSize is calculated by referring to Table 8, where Where N0, N1, N2, and N3 are positive integers.

[0480] In some implementations, if N info >3824, then according to Quantification is performed, among which And calculate TBSize as follows:

[0481] When the bit rate R ≤ 1 / 4 in When the bit rate R > 1 / 4, if Ni ' nfo＞8424 , in otherwise

[0482] When the terminal determines to use block coding based on MCS information or block coding validity information, the terminal determines the number of blocks, the information bit group code rate, and the modulation order. It then determines the block TBsize and overall TBsize based on transmission resource information, the number of information bit groups, the information bit group code rate, and the modulation order. Specifically, this can be:

[0483] Intermediate results for determining the number of information bits corresponding to each information bit group in It is based on the number of resource units N RE Number of transmission layers v, modulation order Q m The bitrate R of the packets n The number of groups N (the number of encoded output bits corresponding to each group) is calculated, specifically... Here It can be an intermediate calculation result, or it can be determined by the final calculated TBsize of the packet based on the number of information bits in each actual transmitted information bit group.

[0484] The number of code blocks C corresponding to each information bit group is determined. The number of code blocks corresponding to each information bit group is the same, where the number of code blocks C is based on the maximum number of information bits. The number of code blocks after code block segmentation, determined by the number of information bits corresponding to the highest code rate information bit group.

[0485] Determine the TBsize (or subTBS) corresponding to each information bit group. n (The actual number of information bits transmitted corresponding to each information bit group), wherein the TBsize calculation of at least one information bit group needs to consider the TB CRC length, which is related to the specific CRC addition method. That is, if only one CRC is added, the TBsize calculation of one information bit group considers the TBCRC length; if a CRC is added to each information bit group, the TBsize calculation of each information bit group considers the TB CRC length. The TBsize characteristics of different information bit groups include at least one of the following:

[0486] TBsize satisfies that it is divisible by 8·C1, which can be based on Among them, subTBSn This represents the TBsize corresponding to the information bit group n. K0 represents a value associated with the encoder input code block length. Alternatively, the TBsize value can be determined directly by looking up a table, as shown in Table 8 above.

[0487] The sum of the TBsize and CRC length of the information bit group is divisible by 8·C2, which can be based on... Calculate, where N CRC This represents a numerical value associated with the CRC length. K0 represents a value associated with the length of the encoder input code block. Alternatively, the TBsize value can be determined by directly looking up a table. For details, please refer to the table lookup method described above. However, the values ​​in the table can be different or the same, and there are no restrictions on this.

[0488] It is important to note that in the calculation of grouped TBsize It could also be It is based on Calculated, for example or K1, K2, A, and B are positive integers.

[0489] Determine the overall TBsize (i.e., the number of information bits in the information bit set): In this way, the final calculated total TBsize can be divided by 8·C1 or 8·C2 after adding CRC (where 8 indicates that the TBsize satisfies an integer number of bytes, 1 byte = 8 bits).

[0490] Example 4:

[0491] This embodiment mainly describes a method for determining redundant version transmission based on redundant version information or feedback information.

[0492] When data is retransmitted, the new data indication can be used to determine whether the data is retransmitted, and the redundancy version index can be used to determine which redundancy version the transmitted data belongs to. For block coding schemes, the initial data transmission contains the data corresponding to all information bit groups. During retransmission, the data corresponding to all information bit groups can be retransmitted by default, or the data corresponding to some information bit groups can be retransmitted. Therefore, when generating the redundancy version signal for retransmission, only the encoded output bit sequence corresponding to the information bit groups to be retransmitted needs to be generated.

[0493] Specifically, during block coding, the generation of the redundant version can be achieved by storing the encoded output bit sequences corresponding to multiple information bit groups into at least one circular buffer, then selecting a rate-matching output bit sequence from the at least one circular buffer, and generating a signal corresponding to the redundant version based on the rate-matching output bit sequence. When retransmission occurs, if all information bit groups are retransmitted by default, the first indication information does not include the retransmission information bit group index information or the weight information of the retransmission information bit groups.

[0494] When retransmitting a portion of the information bit group data, the terminal determines which information bit groups the redundant version signal was generated from based on the encoded data during retransmission, according to the index information of the retransmitted information bit group. For example, the index information of the retransmitted information bit group can be bitmap information: if the number of information bit groups corresponding to different modulation orders is uniformly 2, the bitmap indicator information is 2-bit indicator information; if the number of information bit groups corresponding to different modulation orders is different, the bitmap indicator information is or Q. m / 2 bits indicate information, and the terminal determines the retransmitted information bit group based on the bits that are 1 in the bitmap.

[0495] When retransmitting a portion of the information bit group data, the terminal determines the proportion of the encoded data corresponding to each information bit group in the corresponding retransmitted data based on the proportion information of the retransmitted information bit group. The proportion information of the retransmitted information bit group can refer to the ratio of the data length corresponding to different information bit groups to the retransmitted data length, or the data length information corresponding to different information bit groups, or the number of times the data corresponding to different information bit groups is repeated in the corresponding retransmitted data.

[0496] Taking a packet number N=2 and a redundancy version number of 4 as an example, assuming the current transmission redundancy version is RV1, and the receiving device has correctly decoded the transmission data corresponding to packet 0 based on the previous redundancy versions, then when generating the signal corresponding to RV1, it only needs to be generated based on the encoded output bit sequence corresponding to information bit group 1. Taking code block r as an example, the initial transmission bit selection and retransmission bit selection are illustrated above. Figure 4 As shown, during retransmission, bits are selected from the circular buffer 1 according to the starting position of RV1, and then sequentially selected to obtain a length of 2·E. r The bit sequence, r is the coded code block number. In this embodiment, compared with embodiment two or three, the code block set r only contains the rate-matched output code block r corresponding to information bit group 1, and the length of the rate-matched output code block r corresponding to information bit group 1 is 2·E. r .

[0497] In some implementations, during retransmission, bits can be selected from the circular buffer based on the starting position of RV1, and the length of the selected bit sequence is E. r And by repeating the selection twice, a length of 2·E is obtained. r The bit sequence. That is, at this time, the code block set r only contains the rate-matched output code block r corresponding to group 1, and the length of the rate-matched output code block r corresponding to information bit group 1 is 2·E. r .

[0498] In some implementations, during retransmission, bits can be selected from the circular buffer based on the starting position of RV1, and the length of the selected bit sequence is E. r r is the code block number, meaning that at this time, the code block set r contains only the rate-matched output code block r corresponding to information bit group 1, and the length of the rate-matched output code block r corresponding to group 1 is E. r The length of the output code block r corresponding to the rate-matched information bit group 1 is 2·E. r In this case, the amount of data retransmitted can be reduced.

[0499] More generally, the number of information bit groups Furthermore, when data retransmission is only required based on a portion of the information bit groups, where the portion of the information bit groups includes information bit group n′, the coded code block r corresponding to information bit group n′ can be selected with a length greater than or equal to E during rate matching. r A bit sequence. For example: select a bit sequence of length A. n′ ·E r The rate-matched output bit sequence, where A n′ A is a positive integer greater than or equal to 1. n′ The proportion of the bit set corresponding to block n′ in the code block set r can use a default value, such as A. n′ =1, or, when generating a redundant version of the signal based solely on the bit set corresponding to group n′, A n′ =N, or A can be determined based on the instruction information in the signaling. n′ The value of .

[0500] The ratio of the data length corresponding to the above information bit group n′ to the retransmitted data length can be: Where N′·E r Let N' represent the overall bit sequence length corresponding to the code block set r. If the number of block blocks in the code block set remains unchanged during retransmission and initial transmission, then N' = N.

[0501] The data length information corresponding to the above information bit group n′ can be A n′ ·E r Or A n′The data length information corresponding to the information bit group n′ can be represented in units of rate code block length;

[0502] The number of times the data corresponding to the aforementioned information bit group n′ is repeated in the corresponding retransmitted data can be A. n′ This addresses the situation where data from retransmitted packets is repeatedly selected.

[0503] In some implementations, specific information bit groups may be retransmitted preferentially by default. In this case, the first indication information does not include the index information or the weight information of the retransmitted information bit groups. For example, the data transmission performance of low-bit-rate information bit groups is relatively poor compared to the data transmission performance of high-bit-rate groups. Therefore, each time data is retransmitted, a redundant version signal is generated by default based on the encoded output bit set corresponding to the low-bit-rate information bit group. For example, the number of information bit groups is 2, and the RV transmission order is {0,2,1,3}. The initial RV0 signal is generated and sent based on the encoded output bit set corresponding to information bit group 0 and information bit group 1. During the first retransmission, the RV2 signal is generated and sent based on the encoded output bit set corresponding to information bit group 1. During the second retransmission, the RV2 signal is generated and sent based on the encoded output bit set corresponding to information bit group 0. During the third retransmission, the RV1 signal is generated and sent based on the encoded output bit set corresponding to information bit group 1. During the fourth retransmission, the RV1 signal is generated and sent based on the encoded output bit set corresponding to information bit group 0. During the fifth retransmission, the RV3 signal is generated and sent based on the encoded output bit set corresponding to information bit group 1. During the sixth retransmission, the RV3 signal is generated and sent based on the encoded output bit set corresponding to information bit group 0, and so on, until transmission is complete.

[0504] On the other hand, network-side devices can determine the redundant version generation method based on feedback information from the terminal, which may include:

[0505] Network-side devices determine whether to retransmit data based on the ACK / NACK information associated with TB;

[0506] The network-side device determines which CBs to retransmit based on the ACK / NACK information associated with at least one CB;

[0507] The network-side device determines whether to retransmit some packets or which packets to retransmit based on the index information of the ACK / NACK information or the information bit group recommended for retransmission associated with at least one packet.

[0508] Among them, the ACK / NACK information associated with the group can be the overall decoding correct or incorrect information corresponding to the information bit group. In this case, after the TB is grouped in the block coding scheme, the overall CRC needs to be added to the information bit set corresponding to each information bit group. The receiving device checks whether the overall CRC added to the information bit set corresponding to the information bit group passes the verification to determine whether the group decoding result is correct. If it is correct, it will send back ACK information; otherwise, it will send back NACK information.

[0509] The ACK / NACK information associated with the aforementioned information bit group can be the decoding correctness or error information of multiple code blocks corresponding to the group. That is, when an information bit group is divided into multiple code blocks, each code block is encoded with a CB CRC. The receiving device determines whether the decoding result of the information bit group is correct based on whether the CB CRC check of the multiple code blocks corresponding to the information bit group passes. The ACK / NACK information associated with the information bit group can be:

[0510] When all CB CRC checks pass, the ACK / NACK information associated with the information bit group is ACK; when at least one CB CRC check fails, the ACK / NACK information associated with the information bit group is NACK.

[0511] Alternatively, the ACK / NACK information associated with the information bit group is the number of times the CB CRC checksum of all code blocks corresponding to the information bit group passes or fails.

[0512] The network-side device determines whether to retransmit some information bit groups or which groups to retransmit based on the index information of the suggested retransmission information bit groups. The format of the index information of the suggested retransmission information bit groups can refer to the format of the index information of the retransmission information bit groups mentioned above.

[0513] The network-side equipment determines the proportion of different information bit groups in the retransmitted redundant version data based on the suggested proportion information of the retransmitted information bit groups. The definition and usage of the suggested proportion information of the retransmitted information bit groups can be found in the above-mentioned proportion information of the retransmitted information bit groups.

[0514] Example 5:

[0515] This embodiment illustrates the specific processes of block coding, rate matching, and interleaving, as follows: Figure 7 As shown, it includes:

[0516] Step 1: Divide the set of information bits to be transmitted (e.g., TB) into N information bit groups.

[0517] The set of information bits to be transmitted refers to the TB after adding TB CRC, which is divided into N information bit groups;

[0518] Alternatively, the TB without TB CRC can be grouped first, and then CRC can be added to the information bit set of each group.

[0519] The number of groups is fixed, and can be N=2; or, the number of groups is proportional to the modulation order Q. m Correlation, for example, for 16QAM(Q m =4), the number of groups is 2; for 64QAM(Q m =6), the number of groups is 2 or 3; for 256QAM(Q m =8), the number of groups is 2 or 4; for 1024QAM(Q m =10), the number of groups is 2 or 5.

[0520] The number of information bits corresponding to different information bit groups is determined based on at least one of the following: the number of resource units, the number of transmission layers, the modulation order, the number of blocks, and the block code rate.

[0521] The code rate R of each information bit group n (n=0,1,2,…,N-1) are the same or different, and the code rate E of each information bit group is determined. n For n = 0, 1, 2, ..., N-1, the code rate of each information bit group satisfies (or ), where R is the overall data transmission rate, i.e., the rate of the information bit set.

[0522] Step 2: Divide the information bits corresponding to the N information bit groups into code blocks.

[0523] In this case, the number of code blocks obtained after code block segmentation is the same for different information bit groups, that is, C code blocks are obtained after code block segmentation of the information bits corresponding to each information bit group; specifically, code block segmentation can be performed according to the information bits corresponding to the information bit group with the highest code rate and the number of code blocks C is determined, and the information bits corresponding to other information bit groups are segmented according to the number of code blocks C.

[0524] Step 3: Encode the information bit sets of different information bit groups according to their respective code rates, such as LDPC encoding.

[0525] Optionally, CB CRC is added to the code blocks corresponding to different information bit groups, and they are encoded according to their respective code rates, so that each information bit group corresponds to C encoded output code blocks.

[0526] Optionally, LDPC encoding is performed on N information bit groups to satisfy at least one of the following:

[0527] When LDPC encoding the information bit sets corresponding to different information bit groups, the same LDPC BG and boost factor Z are used.

[0528] The same parity check matrix H is used when LDPC encoding the information bit sets corresponding to different information bit groups;

[0529] Different information bit groups correspond to the same encoded input code block length;

[0530] The encoder output code block length is the same for different information bit groups;

[0531] The mother code rate is the same for different information bit groups.

[0532] Step 4: Rate matching of the encoded output code blocks corresponding to different information bit groups.

[0533] Optionally, the total length of the rate-matched output bit sequence corresponding to different information bit groups (i.e., the sum of the lengths of the C rate-matched output code blocks) is equal;

[0534] Optionally, the total length of the rate-matched output bit sequence corresponding to different information bit groups is determined based on at least one of the following: the number of resource units, the number of transmission layers, the modulation order, and the number of groups.

[0535] Step 5: Concatenate the rate-matched code blocks corresponding to different information bit groups to obtain C code block sets. Each code block set contains N code blocks corresponding to different code rate groups.

[0536] Information bit groups are concatenated with code blocks corresponding to different information bit groups in descending order of code rate. That is, the code blocks output by rate matching corresponding to information bit groups with high code rate are placed first, and the code blocks output by rate matching corresponding to information bit groups with low code rate are placed later, so that the code blocks output by rate matching corresponding to information bit groups with high code rate are sent to the interleaver first.

[0537] Step 6: Perform bit interleaving on each concatenated code block set.

[0538] Interleaving is performed on a per-block basis, using a row-column interleaver, where the interleaver depth (number of rows) equals the modulation order Q. m .

[0539] In some implementations, to ensure that the system bits of each information bit group are fed into the interleaver first, followed by the parity bits, bit selection can be divided into two rounds. In the first round, the system bits to be transmitted are selected from each of the N circular buffers, and in the second round, the parity bits to be transmitted are selected from each of the N circular buffers. Each round of bit selection follows the order of high-rate groups followed by low-rate groups.

[0540] like Figure 8 As shown, taking the number of information bit groups N=2 as an example, when selecting bits, first select the system bits to be transmitted from the circular buffer 0 (which stores the encoded output bits of group 0), then select the system bits to be transmitted from the circular buffer 1 (which stores the encoded output bits of group 1), then select the parity bits to be transmitted from the circular buffer 0 (which stores the encoded output bits of group 0), and then select the parity bits to be transmitted from the circular buffer 1 (which stores the encoded output bits of group 1).

[0541] Step 7: Concatenate the interleaved data, that is, concatenate the code block sets to obtain the modulation input bits.

[0542] Step 8: Perform QAM modulation on the modulated input bit sequence to obtain the target signal and send it.

[0543] Modulated with 256QAM, modulation order Q m Taking 8 as an example, each modulation symbol contains 8 bits. The reliability of these 8 bits can be divided into 4 levels, with every two bits having the same reliability. Based on the modulation order, the information bits to be transmitted are divided into 4 information bit groups. During QAM modulation, the bit set corresponding to each information bit group is mapped to 2 bits of the same reliability. Assuming each information bit group uses the same code rate, the error rate of the code blocks corresponding to each information bit group is statistically analyzed, and the results are as follows... Figure 9a As shown, 901, 902, 903 and 904 represent the performance curves corresponding to the four information bit groups. It can be seen that the bit sets corresponding to different information bit groups are mapped to bits with different reliability during modulation, so their bit error rate performance varies greatly.

[0544] To simplify the encoding and decoding process, the information bits to be transmitted can be divided into two information bit groups. The bit set corresponding to one information bit group is mapped to the four bits with lower reliability during adjustment, while the bit set corresponding to the other code rate group is placed into the four bits with higher reliability during QAM modulation.

[0545] When the fixed number of blocks is 2, assuming that each information bit group uses the same code rate, the error rate of the code block corresponding to each information bit group is statistically analyzed, and the result is as follows: Figure 9b As shown, 905 and 906 represent the performance curves corresponding to the two information bit groups, respectively. It can be seen that the bit sets corresponding to different information bit groups are mapped to bits with different reliability during modulation. Although there is no one-to-one mapping between each group and bits with different reliability as in the case of 4 groups, their bit error rate performance still has a large difference.

[0546] Therefore, in practical processing, different modulation orders are grouped in a unified way, that is, divided into 2 groups and mapped to Q with higher overall reliability respectively. m / 2 bits and Q with low overall reliability m Using 2 bits can improve data transmission performance by allocating an appropriate code rate to the two information bit groups, and also simplifies the encoding and decoding process. The corresponding block coding, rate matching, and interleaving methods are as follows: Figure 10 As shown.

[0547] When LDPC encoding different information bit groups, the encoding rate can be determined based on the encoding rates R0, R1, ..., R of each group. N-1 The number of information bits corresponding to each group, B0, B1, ..., B N-1 Alternatively, the length of the code block after segmentation (including the CRC length) corresponding to each group determines the BG and the boost factor Z of the LDPC encoding for different groups. c n. Alternatively, different groups can use the same LDPC encoding BG and boost factor Z. That is, when LDPC encoding the information bit sets corresponding to different groups, the same parity-check matrix H is used. In this case, the input code block length, the encoder output code block length, and the master code rate are the same for different groups. Specifically, the LDPC encoding BG and boost factor are determined based on the information bit set corresponding to the highest code rate group, including: determining the encoding BG based on the number of information bits (i.e., bit sequence length) or code rate of the highest code rate group; and determining the boost factor Z based on the code block length association parameter K0′ after code block segmentation of the highest code rate group. c This makes the encoder input bit sequence length K = K b ·Z c ≥K′, where K′ is the associated parameter of the code block length after code block segmentation. B′0 represents the sum of the lengths of all code blocks after the set of information bits corresponding to block 0 is divided into code blocks and CB CRC is added, i.e., B′0 = B0 + C·N CB-CRC .

[0548] At this time, the sequence length of each information bit group input to the encoder during LDPC encoding is fixed. Different code rate groups are adapted to the corresponding encoding input bit number requirements by controlling the number of padding bits.

[0549] Taking a scenario with 2 information bit groups, 256QAM modulation, and an overall data transmission code rate of 0.7 as an example, the BLER performance of this embodiment's scheme and a scheme without information bit group processing in a fading channel is compared as follows: Figure 11 and Figure 12As shown, where Figure 11 For different information bit groups, their respective BG and boost factors are determined during encoding. Figure 12 A uniform BG and boost factor are used during encoding for different groups. It can be seen that for different bit rate allocation schemes for different information bit groups (including 0.8 for group 0 and 0.6 for group 1; 0.82 for group 0 and 0.58 for group 1; and 0.84 for group 0 and 0.56 for group 1), specifically corresponding to 1101, 1102, 1103 and 1201, 1202, 1203 in the figure, BLER performance varies, and it achieves performance improvement compared to schemes without group processing (NR baseline coding scheme, specifically corresponding to 1104 and 1204 in the figure).

[0550] The encoding method used in this application embodiment can also be polar code encoding. The different code rates of different groups can be due to the different number of information bits and the number of frozen bits when different groups are encoded in Polar code.

[0551] This application provides a method for indicating encoding-related parameters based on block coding. The method includes a network-side device sending first indication information to a terminal to indicate relevant block coding parameters. The first indication information includes at least one of the following: block coding validity information, the number of information bit groups, information on the N code rates, code rate information of the information bit set, MCS information, information on the number of information bits, transmission resource information, redundancy version indication information, and block coding scheme information. Specifically, the terminal can determine whether to use block coding, the number of information bit groups, the code rate of the information bit groups, and at least one of the encoding scheme based on the MCS information; the terminal can determine the number of information bits based on the transmission resource information, the number of information bit groups, and the code rate information of the information bit groups; and the terminal can determine a redundancy version generation method based on the redundancy version indication information, or the network-side device can determine a redundancy version generation method based on feedback information from the terminal.

[0552] By instructing network-side devices on relevant packet coding parameters, transceiver devices can determine whether to adopt a packet coding scheme and its related parameters, thereby unifying the encoding and decoding process and ensuring data transmission performance. Furthermore, based on terminal feedback, the method for generating redundant version signals is determined, improving data retransmission performance.
