Information sending method, information receiving method and related devices Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information sending method, an information receiving method, and related devices. Background Art

[0002] In order to support emerging business scenarios such as extended reality (XR), integrated communication and perception, and artificial intelligence for network (AI-for-Net) in future communications, a large amount of non-traditional communication information may be generated in the future. This type of information may have a length similar to traditional communication information transmitted on the physical uplink shared channel (PUSCH) and physical downlink shared channel (PDSCH), but may only be transmitted within layer 1 (L1) and will not be reported to higher layers along with traditional communication information.

[0003] Therefore, how to design the transmission method of this type of non-traditional communication information urgently needs to be explored by researchers.

[0004] Summary of the Invention

[0005] The present application provides an information sending method, an information receiving method, and related devices, for use by a first communication device to send first-level information and second-level information, thereby enabling transmission of the second-level information. The second-level information is generated according to a coding method and / or segmentation method determined by a first rule. This enables selection of a suitable coding method and / or segmentation method for the second-level information, which is beneficial for improving the coding performance of the second-level information. The transmission method of the second-level information can be adapted to different business scenarios of non-traditional communication information, thereby enabling flexible transmission of the second-level information.

[0006] In a first aspect, the present application provides an information sending method, which can be performed by a first communication device, which can be a terminal device or a network device, or a component in the terminal device or network device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the functions of the terminal device, or a logic module or software that can implement all or part of the functions of the network device. The method includes:

[0007] The first communication device determines first-level information and second-level information corresponding to the same service type, wherein the first-level information is transmitted on a control channel and / or a shared channel, the second-level information is transmitted on a shared channel, the second-level information is generated according to a coding method and / or a segmentation method determined by a first rule, and the first-level information is used to decode the second-level information; the first communication device outputs the first-level information and the second-level information.

[0008] As can be seen from the above technical solution, the first communication device outputs first-level information and second-level information corresponding to the same service type, and the second-level information is generated according to the encoding method and / or segmentation method determined by the first rule. The transmission of the second-level information is realized. Furthermore, the first communication device determines the encoding method and / or segmentation method of the second-level information according to the first rule. Thereby, the first communication device segments the second-level information according to the segmentation method, and then encodes the segmented second-level information according to the encoding method. Thereby, the first communication device selects the appropriate encoding method and segmentation method based on the situation of the second-level information. This is conducive to improving the encoding performance of the second-level information. It makes up for the problem that the current communication protocol does not support the segmentation of the second-level information. The transmission method of the second-level information can be adapted to different service scenarios of non-traditional communication information, realizing flexible transmission of the second-level information.

[0009] Based on the first aspect, in a possible implementation, the first rule includes: segmenting the second-level information based on the first length, encoding the segmented second-level information by polar code encoding, and the first length is 2 n , n is a positive integer. In this implementation, the first communication device segments the second-level information based on the first length by default and encodes the second-level information using Polar code by default. This enables segmentation and encoding of the second-level information, improving encoding performance. This eliminates the need to indicate the encoding and segmentation methods through command signaling, thereby reducing signaling overhead.

[0010] Based on the first aspect, in one possible implementation, the first length is less than 1024. In this implementation, the first length is less than the maximum encoding length supported by the Polar code encoding scheme. This facilitates the first communication device to encode the segmented second-level information using the Polar code encoding scheme.

[0011] Based on the first aspect, in a possible implementation, the first length is 32, 64, 128, 256, or 512.

[0012] Based on the first aspect, in one possible implementation, the first rule includes: segmenting the second-level information based on a second length, and encoding the segmented second-level information using a low-density parity-check code (LDPC) encoding method. In this implementation, the first communication device segments the second-level information based on the second length by default, and encodes the second-level information using an LDPC code encoding method by default. This achieves segmentation and encoding of the second-level information, improving encoding performance. There is no need to indicate the encoding method and segmentation method through command signaling, thereby reducing signaling overhead.

[0013] Based on the first aspect, in one possible implementation, the second length is determined based on the payload size of the second-level information and the channel coding rate. Thus, an appropriate segment length is selected based on the actual situation of the second-level information, which is conducive to improving coding performance.

[0014] Based on the first aspect, in one possible implementation, the payload size corresponding to the second-level information is less than or equal to 292, or the payload size corresponding to the second-level information is less than or equal to 3824 and the channel coding code rate of the second-level information is less than or equal to 0.25, then the second-level information is segmented with a second length of 3840, and the segmented second-level information is LDPC encoded based on a base graph (BG) 2; or,

[0015] If the payload size of the second-level information is greater than 292, or if the payload size of the second-level information is greater than 3824 and the channel coding rate of the second-level information is greater than 0.25, the second-level information is segmented with a second length of 8448, and LDPC encoding is performed on the segmented second-level information based on BG1, where BG1 is different from BG2. In this implementation, an appropriate segment length and encoding scheme are selected based on the payload size and / or channel coding rate of the second-level information. If the payload size of the second-level information is less than or equal to 292, or if the payload size of the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, the first communication device performs LDPC encoding on the segmented second-level information using BG2. The second length is 3840, which is the maximum length supported by the coding matrix used in the LDPC encoding scheme under BG2. Otherwise, the first communication device performs LDPC encoding on the segmented second-level information based on BG1. The second length is 8448, which is the maximum length supported by the coding matrix used in the LDPC coding method under BG1. This helps improve coding performance.

[0016] Based on the first aspect, in one possible implementation, the first rule includes determining the encoding and / or segmentation method of the second-level information based on the payload size of the second-level information and the channel coding rate of the second-level information. In this implementation, the encoding and / or segmentation method of the second-level information is determined in combination with the payload size of the second-level information and the channel coding rate of the second-level information. This is beneficial for improving the encoding performance of the second-level information. It eliminates the need to indicate the encoding and segmentation method through command signaling, thereby reducing signaling overhead.

[0017] Based on the first aspect, in a possible implementation, the first rule includes: if the payload size corresponding to the second-level information is less than or equal to 384, and the channel coding rate of the second-level information is less than or equal to 0.5, or if the payload size corresponding to the second-level information is less than or equal to 140, the first communication device encodes the second-level information in a non-segmented manner according to the Polar code encoding method; or, if the payload size corresponding to the second-level information is greater than 384, and the channel coding rate of the second-level information is greater than 0.5, or if the payload size corresponding to the second-level information is greater than 140, the second-level information is segmented with a segment length of 3840, and the segmented second-level information is encoded according to the LDPC encoding method. In this implementation, for the case where the payload size of the second-level information is small and / or the channel coding rate is small, the first communication device encodes the second-level information in a non-segmented manner according to the Polar code encoding method. Polar code encoding has better performance and is conducive to improving encoding performance. Otherwise, if the payload size of the second-level information is large and / or the channel coding rate is high, the first communication device encodes the segmented second-level information using the LDPC coding scheme. This is beneficial for improving coding performance. The first communication device segments the second-level information using a segment length of 3840, where 3840 can be the maximum length supported by the coding matrix used by the LDPC coding scheme employed by the first communication device. This enables LDPC encoding of the second-level information.

[0018] Based on the first aspect, in one possible implementation, the first rule includes determining a coding scheme and / or segmentation scheme for the second-level information based on the length of the second-level information after rate matching, the number of available physical resources, and / or the modulation order. This enables selection of an appropriate coding scheme and / or segmentation scheme for the second-level information, improving coding performance. This eliminates the need to indicate the coding scheme and segmentation scheme via command signaling, thereby reducing signaling overhead.

[0019] Based on the first aspect, in a possible implementation method, the first rule includes: if the length of the second-level information after rate matching is less than or equal to the maximum length, the number of segments of the second-level information is determined according to the maximum coding length supported by the Polar code encoding method and the number of available physical resources, the second-level information is segmented according to the number of segments of the second-level information, and the segmented second-level information is encoded according to the Polar code encoding method; or, if the length of the second-level information after rate matching is greater than the maximum length, the number of segments of the second-level information is determined according to the maximum coding length supported by the LDPC encoding method and the number of available physical resources, the second-level information is segmented according to the number of segments of the second-level information, and the segmented second-level information is encoded according to the LDPC encoding method, and the maximum length is determined according to the number of available resources and the modulation order. It can be seen from this that in the case where the length of the second-level information after rate matching is less than or equal to the maximum length, the first communication device can give priority to selecting the Polar coding method to encode the second-level information, thereby improving the coding performance. The first communications device determines the number of segments of the second-level information based on the maximum code length supported by the Polar code encoding scheme and the number of available physical resources, and then segments the second-level information based on the number of segments. This allows the first communications device to perform Polar code encoding on the segmented second-level information. Otherwise, the first communications device preferentially selects the LDPC encoding scheme to encode the second-level information to improve encoding performance. The first communications device determines the number of segments of the second-level information based on the maximum code length supported by the LDPC encoding scheme and the number of available physical resources, and then segments the second-level information based on the number of segments. This allows the first communications device to perform LDPC encoding on the segmented second-level information.

[0020] Based on the first aspect, in one possible implementation, the maximum encoding length supported by the Polar encoding method is 1024.

[0021] Based on the first aspect, in a possible implementation, the maximum code length supported by the LDPC coding method is 3840.

[0022] Based on the first aspect, in a possible implementation, the number of available physical resources is E total The maximum code length supported by the Polar coding method or the maximum code length supported by the LDPC coding method is expressed as N m ; If E rest Less than Then the number of segments C = C1, otherwise the number of segments C = C1 + 1; where E rest =E total -C1×N m , The number of segments of the second level information is determined in combination with the number of available physical resources. rest Less than Then the number of segments can be C1, otherwise the number of segments can be C1 + 1. This is beneficial to improving coding performance and transmission performance.

[0023] Based on the first aspect, in one possible implementation, the first-level information includes first indication information, where the first indication information is used to indicate a coding method used for the second-level information. Indicating the coding method used for the second-level information in the first-level information eliminates the need for additional signaling instructions and reduces signaling overhead.

[0024] Based on the first aspect, in a possible implementation manner, the first indication information is the first field in the first-level information.

[0025] Based on the first aspect, in one possible implementation, when the value of the first field is 0, it indicates that the second-level information is encoded using a Polar code; or when the value of the first field is 1, it indicates that the second-level information is encoded using an LDPC code. This provides an indication of the encoding method for the second-level information, facilitating the first communication device to use an appropriate encoding method to encode the second-level information, thereby improving encoding performance.

[0026] Based on the first aspect, in one possible implementation, the first rule includes: corresponding to the first indication information indicating that the second-level information is encoded using a Polar code encoding method, the second-level information is encoded using a non-segmented method; or corresponding to the first indication information indicating that the second-level information is encoded using an LDPC encoding method, the second-level information is segmented based on a third length. In the implementation, the protocol can specify a segmentation method for the second-level information in combination with the encoding method indicated by the first indication information. This facilitates the first communication device to segment the second-level information using an appropriate segmentation method, and facilitates the subsequent encoding of the segmented second-level information.

[0027] Based on the first aspect, in a possible implementation, the first rule includes: if the modulation order corresponding to the second-level information is less than or equal to the first threshold, the second-level information is encoded in a non-segmented manner according to the Polar code encoding method; or, if the modulation order corresponding to the second-level information is greater than the first threshold, the second-level information is segmented based on a third length, and the segmented second-level information is encoded according to the LDPC encoding method. For the case where the modulation order is small, the payload length of the second-level information is usually small. The first communication device uses the Polar code encoding method to encode the second-level information, which is beneficial to improving the coding performance. For the case where the modulation order is large, the payload length of the second-level information is usually large. The first communication device uses the LDPC encoding method to encode the second-level information, which has better coding performance.

[0028] Based on the first aspect, in one possible implementation, the third length is 3840 or 8448. In this implementation, an example of the third length is the maximum length supported by the coding matrix used when the first communication device uses the LDPC coding method, thereby achieving compatibility with the current LDPC coding method.

[0029] Based on the first aspect, in a possible implementation, the first rule includes: corresponding to the second-level information being the first type of information, encoding the second-level information in a non-segmented manner according to the Polar code encoding method; or corresponding to the second-level information being the second type of information or the third type of information, segmenting the second-level information based on a fourth length, and encoding the segmented second-level information according to the LDPC encoding method. For the first type of information, the length of the second-level information is usually small, and the first communication device uses the Polar code encoding method to encode the second-level information, which is beneficial to improving the encoding performance. For the second type of information or the third type of information, the payload length of the second-level information is usually large, and the first communication device uses the LDPC encoding method to encode the second-level information, which has better encoding performance.

[0030] Based on the first aspect, in one possible implementation, the first type of information is tera-bit multiple-input multiple-output channel state information (T-MIMO CSI), the second type of information is sensing information, and the third type of information is AI-transmitting information. This illustrates several possible application scenarios of the present application. These types of information can be understood as non-traditional communication information, which is information transmitted within Layer 1.

[0031] Based on the first aspect, in one possible implementation, the fourth length is determined based on the payload size and channel coding rate of the second-level information. Thus, the segment length is determined in combination with parameters of the second-level information, facilitating the first communication device to encode the segmented second-level information.

[0032] Based on the first aspect, in one possible implementation, if the payload size corresponding to the second-level information is less than or equal to 292, or if the payload size corresponding to the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, the second-level information is segmented with a fourth length of 3840, and LDPC encoding is performed on the segmented second-level information based on BG2. Alternatively, if the payload size corresponding to the second-level information is greater than 292, or if the payload size corresponding to the second-level information is greater than 3824 and the channel coding rate of the second-level information is greater than 0.25, the second-level information is segmented with a fourth length of 8448, and LDPC encoding is performed on the segmented second-level information based on BG1. If the payload size of the second-level information is less than or equal to 292, or if the payload size of the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, the first communication device uses BG2 to perform LDPC encoding on the segmented second-level information. The fourth length is 3840, which is the maximum length supported by the coding matrix used in the LDPC coding scheme under BG2. Otherwise, the first communication device performs LDPC coding on the segmented second-level information based on BG1. The fourth length is 8448, which is the maximum length supported by the coding matrix used in the LDPC coding scheme under BG1. This helps improve coding performance.

[0033] Based on the first aspect, in one possible implementation, the first rule includes: determining a fifth length based on the payload size of the second-level information and the channel coding rate; segmenting the second-level information based on the fifth length, and encoding the segmented second-level information using an LDPC coding scheme. In this implementation, the first communication device combines the parameter segment length of the second-level information with the segment length, and encodes the segmented second-level information based on the segment length. This facilitates improved coding performance.

[0034] Based on the first aspect, in one possible implementation, if the payload size corresponding to the second-level information is less than or equal to 292, or if the payload size corresponding to the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, the fifth length is 3840; or if the payload size corresponding to the second-level information is greater than 292, or if the payload size corresponding to the second-level information is greater than 3824 and the channel coding rate of the second-level information is greater than 0.25, the fifth length is 8448. In this implementation, if the payload size of the second-level information is less than or equal to 292, or if the payload size of the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, the first communications device performs LDPC encoding on the segmented second-level information using BG2. The fifth length is 3840, which is the maximum length supported by the coding matrix used in the LDPC encoding scheme under BG2. Otherwise, the first communications device performs LDPC encoding on the segmented second-level information based on BG1. The fifth length is 8448, which is the maximum length supported by the coding matrix used in the LDPC coding method under BG1. This helps improve coding performance.

[0035] Based on the first aspect, in one possible implementation, the first-level information includes information about resources used to decode the second-level information, and the length of the first-level information is less than or equal to the sixth length. Thus, it can be seen that the first-level information may only include information about resources used to decode the second-level information. This makes the first-level information more concise, further reduces the payload length of the first-level information, and reduces the blind detection complexity and blind detection overhead of the second communication device.

[0036] Based on the first aspect, in a possible implementation, the sixth length is 70.

[0037] Based on the first aspect, in a possible implementation method, the first-level information includes at least one of the following: a carrier indication field, a partial bandwidth indication field, a time domain resource allocation field, a frequency domain resource allocation field, a virtual resource block (VRB) to physical resource block (PRB) mapping field, a PRB size indication field, a reserved resource field, a zero-power channel state information reference signal (CSI-RS) trigger indication field, a channel access type and cyclic extension field, a sleep indication field, an invalid symbol mode indication field, a scheduling offset indication field, or a channel access type and cyclic extension field.

[0038] Based on the first aspect, in a possible implementation, the first-level information does not include at least one of the following: a shared channel indicator, a new data indicator, a redundancy version (RV), a priority indicator, a hybrid automatic repeat request (HARQ) process number, a downlink assignment index (DAI), a physical downlink shared channel (PDSCH) to HARQ feedback timing, a code block group transmission indicator (CGBTI), a code block group refresh information (CBG flush information), a PDSCH group index, a requested number of PDSCH groups, a one-time HARQ request, a new feedback indication, an antenna port, a transmission configuration indicator (TCI), a sounding reference signal request, a demodulation reference signal (DMRS) sequence initialization, or power control. This makes the first-level information more concise and the payload length of the first-level information shorter.

[0039] Based on the first aspect, in a possible implementation, the second-level information includes at least one of the following: T-MIMO CSI, perception-related information, artificial intelligence-related information, shared channel indication, new data indication, redundancy version, priority indication, HARQ process number, downlink allocation index, PDSCH to HARQ feedback timing, coding block transmission indication, coding block group refresh information, PDSCH group index, requested number of PDSCH groups, one-time HARQ request, new feedback indication, antenna port, transmission configuration indication TCI, sounding reference signal request, DMRS sequence initialization, or power control. That is, the fields originally carried by the first-level information are placed on the second-level information, thereby making the first-level information more streamlined and reducing blind detection overhead.

[0040] Based on the first aspect, in a possible implementation manner, the second-level information includes second-level control information.

[0041] Based on the first aspect, in one possible implementation, the second-stage control information is second-stage uplink control information (2nd-stage UCI), or second-stage downlink control information (2nd-stage DCI), or second-stage sidelink control information (2nd-stage SCI). For different communication scenarios, some possible forms of the second-stage control information are provided.

This illustrates several possible application scenarios of the present application. These types of information can be understood as non-traditional communication information and are transmitted within Layer 1.

[0045] Based on the first aspect, in one possible implementation, the first communication device is a terminal device, and the second communication device is a network device; or, the first communication device is a network device, and the second communication device is a terminal device; or, the first communication device is a first terminal device, and the second communication device is a second terminal device.

[0046] The second aspect of the present application provides an information receiving method, which can be performed by a second communication device, which can be a terminal device or a network device, or a component in the terminal device or network device (for example, a processor, a chip, or a chip system, etc.), or a logic module or software that can implement all or part of the terminal device functions, or a logic module or software that can implement all or part of the network device functions.

[0048] As can be seen from the above technical solution, the second communication device receives the first-level information and the second-level information, and the second communication device determines the decoding method and / or segmentation method of the second-level information based on the second rule. The second communication device decodes the second-level information based on the decoding method and / or segmentation method, as well as the first-level information. This enables the transmission of the first-level information and the second-level information between the first communication device and the second communication device. The second communication device determines the decoding method and / or segmentation method of the second-level information based on the second rule. This enables the second communication device to decode the second-level information using the corresponding decoding method and / or segmentation method. This is conducive to improving the decoding performance of the second-level information. It compensates for the problem that the current communication protocol does not support segmentation of the second-level information. As a result, the transmission method of the second-level information can be adapted to different business scenarios of non-traditional communication information, realizing flexible transmission of the second-level information.

[0049] Based on the second aspect, in a possible implementation, the second rule includes: segmenting the second-level information at a first length, decoding the segmented second-level information by a Polar code decoding method, and the first length is 2 n , n is a positive integer.

[0050] Based on the second aspect, in one possible implementation, the first length is less than 1024. In this implementation, the first length is less than the maximum decoding length supported by the Polar code decoding method. This facilitates the second communication device to decode the segmented second-level information using the Polar code decoding method.

[0051] Based on the second aspect, in a possible implementation, the first length is 32, 64, 128, 256, or 512.

[0052] Based on the second aspect, in one possible implementation, the second rule includes segmenting the second-level information based on a second length and decoding the segmented second-level information using LDPC decoding. In this implementation, the second communication device segments the second-level information based on the second length by default and decodes the second-level information using LDPC decoding by default. This enables segmentation and decoding of the second-level information, improving decoding performance. This eliminates the need to indicate the decoding and segmentation methods through command signaling, thereby reducing signaling overhead.

[0053] Based on the second aspect, in one possible implementation, the second length is determined based on the payload size of the second-level information and the channel coding rate. Thus, an appropriate segment length is selected based on the actual situation of the second-level information, which is conducive to improving decoding performance.

Alternatively, if the payload size corresponding to the second-level information is greater than 292, or if the payload size corresponding to the second-level information is greater than 3824 and the channel coding rate of the second-level information is greater than 0.25, the second-level information is segmented with a second length of 8448, and LDPC decoding is performed on the segmented second-level information based on BG1.

Otherwise, the second communication device performs LDPC decoding on the segmented second-level information based on BG1. The second length is 8448, which is the maximum length supported by the decoding matrix used in the LDPC decoding method under BG1. This helps improve decoding performance.

[0055] Based on the second aspect, in one possible implementation, the second rule includes determining a decoding method and / or a segmentation method for the second-level information based on a payload size of the second-level information and a channel coding rate of the second-level information. In this implementation, the decoding method and / or segmentation method for the second-level information are determined in combination with the payload size of the second-level information and the channel coding rate of the second-level information. This is beneficial for improving the decoding performance of the second-level information.

For example, when n = 2, the polar code encoding matrix with code length N = 4 can be obtained. Figure 3 shows a typical Polar code encoding diagram. The bits to be encoded are sorted into frozen bits and data bits based on their reliability. Generally, bits with higher reliability are set as information bits, while bits with lower reliability are set as frozen bits. The value of the fixed bits is usually set to 0 and is known to both the sender and receiver in actual transmission. As shown in Figure 1, u7, u6, u5, and u3 are the four bits with the highest reliability, so u7, u6, u5, and u3 are all set as information bits. U4, u2, u1, and u0 are the four bits with the lowest reliability, so u4, u2, u1, and u0 are all set as fixed bits.

[0238] 2. Polar code decoding method.

[0239] In recent years, with the inclusion of Polar codes in the 5G standard, research on Polar code decoding has become a hot topic in communications. Currently, mainstream Polar code decoding methods can be divided into two categories based on their decoding timing: sequential Polar code decoding and non-sequential Polar code decoding. Sequential Polar code decoding involves decoding the code bit by bit based on the inherent sequential nature of the Polar code design. Non-sequential Polar code decoding, on the other hand, involves decoding the code using other Polar code structures (such as the Tanner graph and Trelis graph) to output decoding results in parallel.

[0240] Currently, the main sequential decoding algorithms for polar codes include successive cancellation (SC), successive cancellation list (SCL), successive cancellation stack (SCS), and CRC-aided successive cancellation list (CA-SCL). Non-sequential decoding algorithms include belief propagation (BP). In terms of decoding performance, SC decoding suffers the worst, but decoding latency is improved. BP decoding is slightly better than SC. SCL offers significant improvements over the former. Combined with CA-SCL decoding after a cyclic redundancy check (CRC), polar codes can outperform LDPC and turbo codes. Therefore, SCL and CA-SCL are currently the primary methods used in practical systems.

[0241] The advantage of Polar code sequential decoding is its compatibility with the design of Polar codes, making theoretical analysis easy. However, due to its bit-by-bit output, decoding latency is significant, making it unsuitable for communication systems with high real-time requirements. Polar code non-sequential decoding offers the opposite advantage, as it can output multiple bits simultaneously, resulting in lower decoding latency. However, since it doesn't fully match the design of Polar codes, it incurs a certain loss in decoding performance. However, through appropriate design, this loss can be minimized.

[0242] The following introduces LDPC encoding and decoding.

[0243] LDPC code is a channel coding scheme that is very close to the Shannon line, with the characteristics of good performance and low complexity. It has been identified by 3GPP as the 5G data channel coding scheme.

[0244] LDPC coding is done by generating a matrix. The mainstream LDPC code has a quasi-cyclic (QC) structure. By setting the translation amount of each block, it avoids bad structures such as short loops and improves the code distance. Currently, the decoding algorithms for LDPC codes mainly include the minimum sum (MS) decoding algorithm and the BP decoding algorithm. In terms of decoding performance, the BP decoding algorithm is better, but it has a large amount of information storage. c→v The calculation method is complex and not conducive to hardware implementation. Therefore, the offset minimum sum (Offset-MS) and normalized minimum sum (Normalized-MS) decoding algorithms are currently used in actual communication systems. The LDPC code actually used is a cyclic shift matrix that expands the 1 in the basic matrix BG. The BG model of QC-LDPC code is BG = (X, Y, F), where X corresponds to the variable, Y corresponds to the check equation, and F is its edge relationship. After the expansion factor is Z c After the QC expansion of the Tanner graph, we get the bipartite graph G = (V, C, E), where V is the variable node, C is the check node, and E is its edge relationship. The number of columns in the corresponding check matrix N = |V| = Z c |X|, the number of check matrix rows M = |C| = Z c |Y|, the number of non-zero elements in the check matrix is ​​|E|=Z|F|.

[0245] 5G data channels support information bits ranging from 1 to 8448. The standard describes two parity check matrices: BG1 and BG2. The same base graph requires different lifting sizes to accommodate rate matching for different code lengths. This requires storing a list of lifting sizes and shifting values, and implementing rate matching based on these values.

[0246] The 5G LDPC code's shifting value storage includes a lifting size list and a shifting value list that corresponds one-to-one to each row in the lifting size list. The lifting size list can be represented as Table 1:

[0247] Table 1

[0248] The jth row of the Lifting Size list Among them, a j ∈{2,3,5,7,9,11,13,15}, max(k j)∈{7,7,6,5,5,5,4,4}. The row labels of the lifting sizes correspond one-to-one with the column labels of the shifting values. That is, the lifting sizes in each row of the lifting size list correspond to a set of shifting values. During rate matching, the lifting sizes are determined first, and then the corresponding shifting values ​​are selected to construct the check matrix.

[0249] As shown in Table 2, each lifting size group of 5G LDPC codes shares the same set of shifting values. Each BG edge corresponds to a shifting value. When needed, this value is read from the table and applied after modulo calculation.

[0250] Table 2

[0251] In order to support AI-based communications such as extended reality (XR), integrated communication and perception, and artificial intelligence for network (AI-for-Net), a large amount of non-traditional communication information may be generated in the future. Non-traditional communication information is only transmitted within Layer 1 and will not be reported to higher layers along with communication information. Non-traditional communication information may include second-level control information. The second-level control information is similar to the first-level control information transmitted on the physical uplink control channel (PUCCH) and the physical downlink control channel (PDCCH), but the length of the second-level control information is longer than that of the first-level control information. How the second-level control information should be transmitted is a question worth considering. For example, how should the second-level control information of different lengths be segmented and encoded?

[0252] In the present application, in the transmission scenario of non-traditional communication information, the service or service type may be a service service, a communication service service, or a service user service. The service type may also be referred to as a service scenario, a communication service type, or a user scenario. For example, in the transmission scenario of non-traditional communication information, the service type may specifically be an XR service, an augmented reality (AR) service, a virtual reality (VR) service, a perception service, an integrated communication and perception service, an artificial intelligence service service, and / or a T-MIMO service. Non-traditional communication information includes service information of the service, and the length of the service information is generally less than the length of the control information transmitted on the PUCCH and / or PDCCH, and has a length similar to that of the communication information transmitted on the PUSCH and / or PDSCH, but the service information may be transmitted only within L1 and will not be reported to the upper layer together with the communication information. The service information may have lower reliability requirements, and the service information may not carry specific user data.

[0253] This application provides an information sending method, an information receiving method, and related devices for implementing the transmission of second-level information. For details, please refer to the relevant description of the embodiments below.

The first-level information is transmitted on a physical downlink control channel (PDCCH) and / or a physical downlink shared channel (PDSCH). The second-level information is transmitted on a physical downlink shared channel.

[0258] In another possible implementation, the first communication device is a terminal device, and the second communication device is a network device. The first-level information is transmitted on a physical uplink control channel (PUCCH) and / or a physical uplink shared channel (PUSCH).

The second-level information is transmitted on the physical sidelink shared channel.

[0260] It should be noted that, in the several scenarios shown above, the second-level information is transmitted on a shared channel. Optionally, the second-level information may also be transmitted on a newly defined shared channel. For example, a corresponding shared channel is defined in combination with the type of service information carried by the second-level information, and the second-level information is transmitted on the newly defined shared channel. For example, the second-level information carries perception-related information, and the newly defined shared channel may be called a physical sensing downlink shared channel (PSDSCH) or a physical sensing uplink shared channel (PSUSCH), and the second-level information may be carried on PSDSCH or PSUSCH. For another example, the second-level information carries AI intelligent training data, and the newly defined shared channel may be called a physical artificial intelligence downlink shared channel (PADSCH) or a physical artificial intelligence uplink shared channel (PAUSCH).

For another example, the first communication device is a first terminal device, and the second communication device is a second terminal device. The second-stage control information is the second-stage sidelink control information (2 nd -stage SCI).

[0263] Optionally, the name of the second-level information may also be a newly defined name. For example, the second-level information carries perception-related information, and the second-level information may be called the second-level uplink perception information (2 nd -stage uplink sensing information, 2 nd -stageUSI) or second-stage downlink perception information (2 nd -stagedownlink sensing information, 2 nd -stage DSI). For another example, the second-level information is carried in AI intelligent training data, and the second-level information can be called the second-level uplink artificial intelligence information (2 nd -stage uplink artificial intelligence information, 2 nd -stageUAI) or second-stage downlink artificial intelligence information (2 nd -stage downlink artificial intelligence information, 2 nd -stage DAI).

[0264] The first-level information is used to decode the second-level information. Optionally, the first-level information includes information used to decode the resources occupied by the second-level information. That is, the second communication device can parse the first-level information to determine the time-frequency resource location occupied by the second-level information. The second communication device can receive the second-level information at the time-frequency resource location. The following illustrates some possible fields for information used to decode the resources occupied by the second-level information.

[0265] Optionally, the first-level information includes at least one of the following: a carrier indication field, a partial bandwidth indication field, a time domain resource allocation field, a frequency domain resource allocation field, a VRB to PRB mapping field, a PRB size indication field, a reserved resource field, a zero-power CSI-RS trigger indication field, a channel access type and cyclic extension field, a sleep indication field, an invalid symbol mode indication field, a scheduling offset indication field, or a channel access type and cyclic extension field.

[0266] The carrier indication field is used to indicate the component carrier for which the DCI is intended when cross-carrier scheduling occurs. The carrier indication field occupies a maximum of 3 bits. The fractional bandwidth indication field is used to indicate resource allocation in the time domain. The fractional bandwidth indication field occupies a maximum of 6 bits.

[0267] The Time Domain Resource Allocation field indicates resource allocation in the time domain. It occupies a maximum of 6 bits. The Frequency Domain Resource Allocation field indicates the resource blocks allocated on a component carrier. The number of bits occupied by the Frequency Domain Resource Allocation field is determined by the fractional bandwidth size and the resource allocation type.

[0268] The VRB to PRB mapping field is used to indicate interleaved or non-interleaved VRB to PRB mapping, and the VRB to PRB mapping field occupies a maximum of 1 bit.

[0269] The PRB size indication field is used to indicate the PDSCH bundling size. The PRB size indication field occupies a maximum of 1 bit.

[0270] The reserved resource field indicates the use of reserved resources in data transmission. The reserved resource field occupies a maximum of 2 bits.

[0275] The Scheduling Offset Indication field is used to control inter-slot scheduling for energy conservation. The Scheduling Offset Indication field occupies a maximum of 1 bit. The Channel Access Type and Cyclic Extension fields occupy a maximum of 2 bits.

[0276] Optionally, the first-level information does not include at least one of the following: shared channel indication, new data indication, redundant version, priority indication, HARQ process number, downlink allocation index, PDSCH to HARQ feedback timing, coding block transmission indication, coding block group refresh information, PDSCH group index, requested number of PDSCH groups, one-time HARQ request, new feedback indication, antenna port, transmission configuration indication TCI, sounding reference signal request, DMRS sequence initialization, or power control.

[0277] The shared channel indicator indicates whether the current shared channel carries second-level information. The new data indicator indicates whether the shared channel is transmitting initial or retransmitted data. The redundancy version indicates the redundancy version corresponding to the retransmitted data. The priority indicator directs the priority of HARQ confirmation. The HARQ process number indicates which HARQ process the terminal device should use for soft combining for this transmission. The downlink allocation index indicates the HARQ codebook information when control information needs to be transmitted on the data channel.

[0278] PDSCH to HARQ Feedback Timing indicates when HARQ feedback is sent relative to PDSCH transmission. Coded Block Transmit Indication indicates the code block group for retransmission. Coded Block Group Refresh Information indicates soft buffer refresh. The PDSCH Group Index indicates the PDSCH group in unlicensed spectrum and controls the HARQ codebook. Requested Number of PDSCH Groups indicates whether HARQ feedback in unlicensed spectrum should include only the current PDSCH group or other PDSCH groups.

[0279] The one-time HARQ request is used to request the activation of a HARQ feedback for the HARQ processes of all carriers and PDSCH groups in the unlicensed spectrum. The new feedback indication is used to indicate whether the receiving end has received HARQ feedback in the unlicensed spectrum. The antenna port refers to the antenna port used for data transmission and the antenna port used by other terminal devices. The transmission configuration indication is used to indicate the quasi co-located (QCL) relationship of the downlink transmission. The SRS request is used to indicate the SRS transmission request. The DMRS sequence initialization is used to select two pre-configured DMRS sequence initial values. The power control is used to notify the terminal device to adjust the transmission power of the control information.

[0280] This makes the first-level information more concise, and the first-level information is encoded in a non-segmented manner. The payload size of the first-level information is further reduced, thereby reducing the blind detection complexity of the second communication device.

[0281] Optionally, the length of the first-level information is less than or equal to the sixth length. For example, the sixth length is 70.

[0282] Optionally, the second-level information includes at least one of the following: T-MIMO CSI, perception-related information, artificial intelligence-related information, shared channel indication, new data indication, redundancy version, priority indication, HARQ process number, downlink allocation index, PDSCH to HARQ feedback timing, coding block transmission indication, coding block group refresh information, PDSCH group index, requested number of PDSCH groups, one-time HARQ request, new feedback indication, antenna port, transmission configuration indication TCI, sounding reference signal request, DMRS sequence initialization, or power control. T-MIMMO CSI includes T1 bit-level MIMO channel state information. Perception-related information is used to provide perception-related data. Artificial intelligence-related information includes artificial intelligence training information and / or artificial intelligence reasoning information. For the functions of other fields, please refer to the relevant introduction mentioned above. It can be seen that the fields originally in the first-level information are moved to the second-level information, making the first-level information more streamlined.

[0283] The first-level information and the second-level information correspond to the same service type, meaning they target the same service. Specifically, the first communications device sends the first-level information and the second-level information for the same service. This allows the second communications device to parse the first-level information and determine the time-frequency resources containing the second-level information. For information about service types, please refer to the previous section. The second communications device can then parse the second-level information to obtain data related to the service. For example, in certain specific communication scenarios, the names of the first-level information and the second-level information may indicate that the first-level information and the second-level information target the same service. For example, in a sidelink (SL) scenario, the first-level information is the first-level SCI, and the second-level information is the second-level SCI. For another example, the first-level information includes a second field that indicates the service. For example, if the second-level information carries sensory information, the first-level information includes a second field that indicates the sensory service. Therefore, both the first-level information and the second-level information are sent for the sensory service.

[0284] Optionally, the first-level information is carried in at least one of the following: a scheduling request (SR), a hybrid automatic repeat request acknowledgement (HARQ-ACK), or channel state information (CSI). The second-level information is carried in an intra-radio access network (intra-RAN) message, and / or the T-MIMO CSI is equal to the control information with a larger payload size.

[0285] The second level information is generated according to the encoding method and / or segmentation method determined by the first rule.

[0286] Some possible implementations of the first rule are described below.

[0287] 1. The first rule includes: segmenting the second level information based on the first length, and encoding the segmented second level information using the Polar coding method. The first length is 2 n , n is a positive integer.

[0288] Optionally, the first length is less than 1024, that is, less than the maximum encoding length 1024 supported by the Polar encoding method. For example, the first length is 32, 64, 128, 256, or 512. That is, the first length is 2 n , n is equal to 5, 6, 7, 8, or 9.

[0289] In this implementation, the first communication device segments the second-level information using the first length by default, so that the length of each segmented second-level information is the first length. Of course, the length of the final segment of the second-level information obtained after segmentation can be less than or equal to the first length. For example, if the length of the second-level information is 2250 and the first length is 512, then the number of segments obtained by the first communication device from segmenting the second-level information is 5. Four of the segments have a length of 512, and one segment has a length of 202. The first communication device then encodes the segmented second-level information using Polar code by default.

[0290] 2. The first rule includes: segmenting the second-level information based on the second length, and encoding the segmented second-level information using an LDPC encoding method.

[0291] Optionally, the second length is determined according to the payload size and channel coding rate of the second-level information. Optionally, the first-level information includes information indicating the channel coding rate of the second-level information.

[0292] For example, if the payload size corresponding to the second-level information is less than or equal to 292, or the payload size corresponding to the second-level information is less than or equal to 3824 and the channel coding code rate of the second-level information is less than or equal to 0.25, the second-level information is segmented with a second length of 3840, and the segmented second-level information is LDPC encoded based on BG2; or, if the payload size corresponding to the second-level information is greater than 292, or the payload size corresponding to the second-level information is greater than 3824 and the channel coding code rate of the second-level information is greater than 0.25, the second-level information is segmented with a second length of 8448, and the segmented second-level information is LDPC encoded based on BG1.

[0293] The first communication device segments the second-level information with a second length of 3840. That is, the length of each segmented second-level information is 3840. Of course, the length of the final segment of the second-level information obtained after segmentation can be less than or equal to 3840. The first communication device segments the second-level information with a second length of 8448. That is, the length of each segmented second-level information is 8448. Of course, the length of the final segment of the second-level information obtained after segmentation can be less than or equal to 8448.

[0294] When the payload size of the second-level information is less than or equal to 292, and when the payload size of the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, the first communication device performs LDPC encoding on the segmented second-level information based on BG2. This helps improve the error correction performance of the second-level information by the second communication device. Otherwise, the first communication device performs LDPC encoding on the segmented second-level information based on BG1. This achieves higher coding performance and improves the error correction performance of the second communication device for the second-level information.

[0295] 3. The first rule includes: determining the encoding method and / or segmentation method of the second-level information according to the payload size of the second-level information and the channel coding rate of the second-level information.

[0296] Optionally, if the payload size corresponding to the second-level information is less than or equal to 384, and the channel coding code rate of the second-level information is less than or equal to 0.5, or the payload size corresponding to the second-level information is less than or equal to 140, the second-level information is encoded in a non-segmented manner according to the Polar code encoding method; or, if the payload size corresponding to the second-level information is greater than 384, and the channel coding code rate of the second-level information is greater than 0.5, or the payload size corresponding to the second-level information is greater than 140, the second-level information is segmented with a segment length of 3840, and the segmented second-level information is encoded according to the LDPC encoding method.

[0297] The first communication device segments the second-level information with a segment length of 3840, that is, the length of each segmented second-level information is 3840. Of course, the length of the last segment of the second-level information obtained after segmentation can be less than or equal to 3840.

[0298] In the communication protocol, the first rule in the third implementation can be expressed as: if A≤384and R≤0.5or A≤140 Use Polar code and no CB segmentation; else Use LDCP and CB segmentation according to K cb =3840; end if

[0299] Where A is the payload size of the second-level information, and R is the channel coding rate of the second-level information. If A≤384 and R≤0.5, or A≤140, the first communication device encodes the second-level information in a non-segmented manner according to the Polar code encoding method. Otherwise, the first communication device encodes the second-level information in a K cb =3840 is the segment length for segmenting the second-level information, and encoding the segmented second-level information according to the LDPC encoding method.

[0300] As can be seen from this, if the payload size of the second-level information is small and / or the channel coding rate of the second-level information is low, the first communication device can use Polar code encoding to encode the second-level information. If the payload size of the second-level information is large and / or the channel coding rate of the second-level information is high, the first communication device can use LDPC encoding to encode the second-level information. This helps improve coding performance.

[0301] 4. The first rule includes: determining the encoding method and / or segmentation method of the second-level information according to the length of the second-level information after rate matching, the number of available physical resources and / or the modulation order.

[0302] Optionally, if the length of the second-level information after rate matching is less than or equal to the maximum length, the number of segments of the second-level information is determined based on the maximum coding length supported by the Polar code encoding method and the number of available physical resources, the second-level information is segmented based on the number of segments of the second-level information, and the segmented second-level information is encoded based on the Polar code encoding method; or, if the length of the second-level information after rate matching is greater than the maximum length, the number of segments of the second-level information is determined based on the maximum coding length supported by the LDPC encoding method and the number of available physical resources, the second-level information is segmented based on the number of segments of the second-level information, and the segmented second-level information is encoded based on the LDPC encoding method.

[0303] The maximum length is determined based on the number of available physical resources and the modulation order. Optionally, the maximum length is equal to the number of available physical resources multiplied by the modulation order. Optionally, the first-level information carries or indicates the modulation order.

[0304] For example, if the second-level information is the second-level UCI, and the length of the second-level information after rate matching is G UCI2 ≤E max , the maximum code length supported by the Polar code encoding method is 1024, the first communication device determines the number of segments of the second-level information based on the maximum code length supported by the Polar code encoding method and the number of available physical resources, the first communication device segments the second-level information based on the number of segments of the second-level information, and encodes the segmented second-level information according to the Polar code encoding method. If the length of the second-level information after rate matching G UCI2 >E maxThe maximum coding length supported by the LDPC coding method is 3840. The first communication device determines the number of segments of the second-level information based on the maximum coding length supported by the LDPC coding method and the number of available physical resources. The first communication device segments the second-level information according to the number of segments of the second-level information, and encodes the segmented second-level information according to the LDPC coding method.

[0305] Optionally, the number of available physical resources is E total The maximum code length supported by Polar coding or the maximum code length supported by LDPC coding is expressed as N m If E rest If it is less than the first threshold, the number of segments C = C1, otherwise the number of segments C = C1 + 1. rest =E total -C1×N m , Optionally, the first threshold is greater than or equal to For example, the first threshold is equal to E rest Indicates the remaining available physical resources. That is, if E rest Greater than or equal to N m The number of segments can be increased by one, which is beneficial to improving encoding performance.

[0306] In the communication protocol, the first rule in the fourth implementation can be expressed as: if G UCI2 ≤E max Use Polar code and CB segmentation according to N max =1024; else Use LDCP and CB segmentation according to K cb =3840; end if

[0307] Among them, G UCI2 is the second level information after rate matching, E max is the maximum length. N max K is the maximum code length supported by the Polar code encoding method. cb The maximum code length supported by the LDPC coding method.

[0308] 5. The first-level information includes first indication information, where the first indication information is used to indicate an encoding scheme for the second-level information. The first rule includes encoding the second-level information in a non-segmented manner if the first indication information indicates that the second-level information is encoded using a Polar code encoding scheme; or segmenting the second-level information based on a third length if the first indication information indicates that the second-level information is encoded using an LDPC encoding scheme.

[0309] Optionally, the first indication information is the first field in the first-level information. For example, the first field is 1 bit, 2 bits, or 3 bits. Specifically, this application does not limit the length of the first field.

[0310] Optionally, when the value of the first field is 0, it indicates that the second-level information is encoded using a Polar code encoding method; when the value of the first field is 1, it indicates that the second-level information is encoded using an LDPC encoding method. Alternatively, when the value of the first field is 0, it indicates that the second-level information is encoded using an LDPC encoding method; when the value of the first field is 0, it indicates that the second-level information is encoded using a Polar code encoding method.

[0311] For example, the first level information is 1 st -stage DCI, the second level information is 2 nd -stage DCI. 2 nd -stage DCI physical resources and channel coding type information, segment information are all in 1 st -stage DCI is reflected in 1 st -New instruction 2 in stage DCI nd -stage DCI resource configuration fields (e.g., time-frequency resource allocation information, resource reservation period, DMRS pattern), 2 nd -stage UCI format, modulation and coding scheme (MCS), Beta offset indicator (Beta_offset indicator), number of DMRS ports (number of DMRS ports) and code type indicator (code type indicator). That is, the first field is the code type indicator, which is used to indicate 2 nd -stage DCI uses the encoding method. Beta offset indication is a parameter used to calculate the number of resource elements (REs).

[0312] In this implementation, if the first indication information instructs the first communication device to encode the second-level information using a Polar code encoding scheme, the first communication device encodes the second-level information in a non-segmented manner by default. If the first indication information instructs the first communication device to encode the second-level information using an LDPC encoding scheme, the first communication device segments the second-level information based on the third length.

[0313] Optionally, the third length is 3840 or 8448. This is the maximum length supported by the coding matrix used in the LDPC coding scheme. Of course, if the coding matrix used in the LDPC coding scheme in the future can support a larger length, the third length can also be other values.

[0314] In the communication protocol, the first rule in the fifth implementation can be expressed as: if Code Type indicator == 0 Use Polar code and no CB segmentation; else Use LDCP and CB segmentation according to K cb =3840; end if

[0315] Among them, K cb is the third length, and the third length is 3840.

[0316] Optionally, the first indication information is also used to indicate the segmentation method used for the second-level information. For example, when the value of the first indication information is 1, it instructs the first communication device to encode the second-level information in a non-segmented manner according to the Polar code encoding method. When the value of the first indication information is 0, it instructs the first communication device to segment the second-level information based on the third length, and encode the segmented second-level information according to the LDPC encoding method. For another example, when the value of the first indication information is 0, the first communication device encodes the second-level information in an LDPC encoding method, and the first communication device segments the second-level information based on the third length. When the value of the first indication information is 1, it instructs the first communication device to encode the second-level information in a non-segmented manner according to the Polar code encoding method.

[0317] VI. First Rule: If the modulation order corresponding to the second-level information is less than or equal to the first threshold, the second-level information is encoded in an unsegmented manner using the Polar code encoding scheme. Alternatively, if the modulation order corresponding to the second-level information is greater than the first threshold, the second-level information is segmented based on a third length and then encoded using the LDPC encoding scheme.

[0318] Optionally, the first-level information indicates a modulation order of the second-level information. For example, the first-level information includes a field for indicating the modulation order of the second-level information.

[0319] Optionally, the first threshold is 2. Of course, the first threshold may also be other values, which may be determined in combination with the encoding performance of various encoding modes.

[0320] Optionally, the third length is 3840 or 8448. This is the maximum length supported by the coding matrix used in the LDPC coding scheme. Of course, if the coding matrix used in the LDPC coding scheme in the future can support a larger length, the third length can also be other values.

[0321] Specifically, if the modulation order of the second-level information is less than or equal to 2, the first communication device may encode the second-level information in a non-segmented manner according to the Polar code encoding scheme. Generally, if the modulation order used is small, the length of the second-level information is short. Therefore, when the modulation order of the second-level information is less than or equal to 2, the first communication device uses the Polar code encoding scheme to encode the information, resulting in better coding performance. If the modulation order of the second-level information is greater than 2, the first communication device segments the second-level information based on a third length and then encodes the segmented second-level information according to the LDPC encoding scheme. When the modulation order of the second-level information is greater than 2, the first communication device uses the LDPC encoding scheme to encode the information, resulting in better coding performance. The first communication device segments the second-level information based on the third length, such that the length of each segmented segment of the second-level information is the third length. Of course, the length of the final segment of the second-level information obtained after segmentation can be less than or equal to the third length.

[0322] 7. The first rule includes: if the second-level information is first-type information, the second-level information is encoded in a non-segmented manner according to the Polar code encoding method; or, if the second-level information is second-type information or third-type information, the second-level information is segmented based on a fourth length and then encoded according to the LDPC encoding method.

[0323] Specifically, the first communication device segments the second-level information such that the length of each segment of the second-level information after segmentation is the fourth length. Of course, the length of the final segment of the second-level information obtained after segmentation may be less than or equal to the fourth length. The first communication device then encodes the segmented second-level information according to the LDPC encoding scheme.

[0324] Optionally, the first type of information is T-MIMO CSI, the second type of information is perception-related information, and the third type of information is AI training information. The data length of T-MIMO CSI is usually short, so the first communication device encodes the second-level information according to the Polar code encoding method, which is beneficial to improving coding performance. The data lengths corresponding to the perception-related information and AI training data are respectively longer, so the first communication device encodes the segmented second-level information according to the LDPC encoding method, which is beneficial to improving coding performance.

[0325] Optionally, the fourth length is determined based on the payload size and channel coding rate of the second-level information. For example, if the payload size corresponding to the second-level information is less than or equal to 292, or if the payload size corresponding to the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, then the fourth length is 3840; or if the payload size corresponding to the second-level information is greater than 292, or if the payload size corresponding to the second-level information is greater than 3824 and the channel coding rate of the second-level information is greater than 0.25, then the fourth length is 8448. That is, the maximum length supported by the coding matrix used in the LDPC coding method. Of course, if the coding matrix used in the future LDPC coding method can support a larger length, the fourth length can also be other values.

[0326] For example, if the payload size of the second-level information is less than or equal to 292, or if the payload size of the second-level information is less than or equal to 3824 and the channel coding code rate of the second-level information is less than or equal to 0.25, the first communication device segments the second-level information with a fourth length of 3840, and then performs LDPC encoding on the segmented second-level information based on BG2; otherwise, the first communication device segments the second-level information with a fourth length of 8448, and then performs LDPC encoding on the segmented second-level information based on BG1.

[0327] In one possible implementation, the communication protocol may define different formats of second-level information according to the type of information carried by the second-level information. For example, the format of the second-level information carrying the first type of information is the second-level information format A. The format of the second-level information carrying the second type of information is the second-level information format B. The format of the second-level information carrying the third type of information is the second-level information format C. For example, the second-level information is 2 nd -stage UCI, the format of the second-level information carrying the first type of information is 2 nd -stage UCI Format-A, the format of the second-level information carrying the second type of information is 2 nd -stage UCI Format-B, the second level information carrying the third type of information is 2 nd-stage UCI Format-C. For another example, the second level information is 2 nd -stage DCI, the format of the second-stage information carrying the first type of information is 2 nd -stage DCI Format-A, the format for carrying the second type of information is 2 nd -stage DCI Format-B, the second level information carrying the third type of information is 2 nd -stageDCI Format-C.

[0328] 8. The first rule includes: determining a fifth length according to the payload size of the second-level information and the channel coding rate; segmenting the second-level information based on the fifth length, and then encoding the segmented second-level information according to the LDPC coding method.

[0329] In this implementation, the first-level information is transmitted on a control channel, and the second-level information is transmitted on a shared channel. The first communication device segments the second-level information so that the payload length of each segment of the second-level information is the fifth length. Of course, the length of the final segment of the second-level information obtained after segmentation can be less than or equal to the fifth length. The first communication device then encodes the segmented second-level information using the LDPC encoding scheme.

[0330] Optionally, if the payload size corresponding to the second-level information is less than or equal to 292, or if the payload size corresponding to the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, the fifth length is 3840; alternatively, if the payload size corresponding to the second-level information is greater than 292, or if the payload size corresponding to the second-level information is greater than 3824 and the channel coding rate of the second-level information is greater than 0.25, the fifth length is 8448. This is the maximum length supported by the coding matrix used in the LDPC coding method. Of course, if the coding matrix used in the future LDPC coding method can support a larger length, the fifth length can also be other values.

[0331] Optionally, the second level information includes layer L1 information.

[0332] Optionally, the second level information includes at least one of the following: T-MIMO CSI, perception-related information, or AI training information.

[0333] 402. The first communication device outputs first-level information and second-level information.

[0334] For the first-level information and the second-level information, please refer to the related introduction of the aforementioned step 401.

[0335] Specifically, the first communication device may output the first level information and the second level information to the second communication device.

[0336] It should be noted that the first communication device can send the first-level information and the second-level information at the same time, or can send the first-level information first and then send the second-level information. This application does not limit this.

[0337] 403. The second communication device determines a decoding method and / or a segmentation method for the second-level information according to a second rule.

[0338] The following describes some possible implementations of the second rule. This application is still applicable to other implementations, and this application does not limit them specifically.

[0339] 1. Based on the implementation method 1 of the first rule in step 401 above, optionally, the second rule includes: segmenting the second-level information based on the first length, and decoding the segmented second-level information by Polar code decoding, where the first length is 2 n , n is a positive integer.

It should be noted that the second communication device segments the second-level information with a segment length of 3840, that is, the length of each segmented second-level information is 3840. Of course, the length of the last segment of the second-level information obtained after segmentation can be less than or equal to 3840.

Based on the fourth implementation method of the first rule in the above step 401, optionally, the second rule includes: determining the decoding method and / or segmentation method of the second-level information according to the length of the second-level information received by the second communication device, the number of available physical resources and / or the modulation order.

Alternatively, if the length of the second-level information received by the second communication device is greater than the maximum length, the number of segments of the second-level information is determined based on the maximum decoding length supported by the LDPC decoding method and the number of available physical resources, the second-level information is segmented based on the number of segments of the second-level information, and the segmented second-level information is decoded based on the LDPC decoding method. For details about the maximum length, please refer to the relevant description of step 401 above.

[0347] Optionally, the maximum decoding length supported by the Polar code decoding method is 1024.

[0348] Optionally, the maximum decoding length supported by the LDPC decoding method is 3840.

[0349] Optionally, the total number of available physical resources is E total The maximum decoding length supported by Polar decoding or the maximum decoding length supported by LDPC decoding is expressed as N m ; If E rest If it is less than the first threshold, the number of segments C = C1, otherwise the number of segments C = C1 + 1.rest =E total -C1×N m , Optionally, the first threshold is greater than or equal to For example, the first threshold is equal to E rest Indicates the remaining available physical resources. That is, if E rest Greater than or equal to N m The number of segments can be increased by one if the value is half of the value.

[0350] 5. In a fifth implementation of the first rule in step 401 above, the first-level information includes first indication information, which indicates an encoding scheme used for the second-level information. Optionally, the second rule includes: if the first indication information indicates that the second-level information is encoded using a Polar code encoding scheme, decoding the second-level information in a non-segmented manner according to a Polar decoding scheme; or, if the first indication information indicates that the second-level information is encoded using an LDPC encoding scheme, segmenting the second-level information based on a third length and decoding the segmented second-level information according to an LDPC decoding scheme.

[0353] Regarding the third length, please refer to the above introduction.

[0354] 7. Based on the sixth implementation method of the first rule in step 401 above, optionally, the second rule includes: if the second-level information is the first type of information, decoding the second-level information in an unsegmented manner according to the Polar code decoding method; or, if the second-level information is the second type of information or the third type of information, segmenting the second-level information based on a fourth length, and then decoding the segmented second-level information according to the LDPC decoding method.

[0355] For the first type of information, the second type of information and the third type of information, please refer to the relevant introduction of the aforementioned step 401, which will not be repeated here. For the fourth length, please refer to the relevant introduction of step 401, which will not be repeated here.

[0356] 8. Based on the seventh implementation method of the first rule in the above step 401, optionally, the second rule includes: determining the fifth length according to the payload size and channel coding code rate of the second-level information; segmenting the second-level information based on the fifth length, and decoding the segmented second-level information according to the LDPC decoding method.

[0357] In this implementation, the first-level information is transmitted on a control channel, and the second-level information is transmitted on a shared channel. The second communication device segments the second-level information so that the payload size of each segment of the second-level information is the fifth length. Of course, the length of the final segment of the second-level information obtained after segmentation can be less than or equal to the fifth length. The second communication device then decodes the segmented second-level information using an LDPC decoding scheme.

[0358] Optionally, if the payload size corresponding to the second-level information is less than or equal to 292, or the payload size corresponding to the second-level information is less than or equal to 3824 and the channel coding rate of the second-level information is less than or equal to 0.25, then the fifth length is 3840; or, if the payload size corresponding to the second-level information is greater than 292, or the payload size corresponding to the second-level information is greater than 3824 and the channel coding rate of the second-level information is greater than 0.25, then the fifth length is 8448.

[0359] 404. The second communication device decodes the second-level information according to the decoding mode and / or segmentation mode and the first-level information.

[0360] Specifically, the second communication device determines the resource location of the second-level information based on the first-level information. The second communication device then receives the second-level information from the resource location. The second communication device segments the second-level information according to the segmentation method, and then decodes the segmented second-level information according to the decoding method.

[0361] In an embodiment of the present application, the first communication device determines the first-level information and the second-level information corresponding to the same service type. The first-level information is transmitted on the control channel and / or the shared channel. The second-level information is transmitted on the shared channel. The second-level information is generated according to the coding method and / or segmentation method determined by the first rule. The first-level information is used to decode the second-level information. The first communication device outputs the first-level information and the second-level information. It can be seen that the second-level information is generated according to the coding method and / or segmentation method determined by the first rule, thereby realizing the transmission of the second-level information. It is conducive to improving the coding performance of the second-level information. It makes up for the problem that the current communication protocol does not support segmentation of the second-level information. The transmission method of the second-level information can be adapted to different service scenarios of non-traditional communication information, thereby realizing flexible sending of the second-level information.

[0362] The present application also provides another embodiment, and the technical solution of this embodiment is introduced below in conjunction with steps a to c.

[0363] Step a: The second communication device sends first-level information 1 to the first communication device. The first-level information 1 includes first indication information, which is used to indicate the encoding method used for the second-level information. Correspondingly, the first communication device receives the first-level information 1 from the second communication device.

[0364] Optionally, the first level information 1 is transmitted on the control channel. For example, the first level information 1 is 1 st -stage DCI, 1 st -stage DCI is transmitted on PUCCH.

[0365] Optionally, the first indication information is the first field in the first-level information 1. For example, the first field is 1 bit, 2 bits, or 3 bits, and the present application does not impose any limitation on the length of the first field.

[0366] Optionally, when the value of the first field is 0, it indicates that the second-level information is encoded using a Polar code encoding method; when the value of the first field is 1, it indicates that the second-level information is encoded using an LDPC encoding method. Alternatively, when the value of the first field is 0, it indicates that the second-level information is encoded using an LDPC encoding method; when the value of the first field is 0, it indicates that the second-level information is encoded using a Polar code encoding method.

[0367] For example, the first level information 1 is 1 st -stage DCI, the second level information is 2 nd -stage UCI. 1 st -New instruction 2 in stage DCI nd -stage UCI resource configuration fields (e.g., time-frequency resource allocation, resource reservation period, DMRS pattern, 2 nd -stage UCI format, MCS, Beta_offset indicator, number of DMRS ports and coding type indication. That is, the first field is the coding type indication, which is used to indicate 2 nd -stage UCI uses the encoding method. For example, as shown in Table 1, 1 st -stage DCI adds encoding type indication.

[0368] Table 1

[0369] In this implementation, if the first indication information indicates that the second-level information is encoded using a Polar code encoding method, the first communication device encodes the second-level information in a non-segmented manner by default. If the first indication information indicates that the second-level information is encoded using an LDPC encoding method, the first communication device segments the second-level information based on the third length. Optionally, the third length is 3840 or 8448. That is, the maximum length supported by the coding matrix used in the LDPC encoding method. Of course, if the coding matrix used in the LDPC encoding method in the future can support a larger length, the third length can also be other values.

[0370] In the communication protocol, it can be expressed as follows: if Code Type indicator == 0 Use Polar code and no CB segmentation; else Use LDCP and CB segmentation according to K cb =3840; end if

[0371] Among them, K cb The third length.

[0372] Optionally, the first indication information is also used to indicate the segmentation method used for the second-level information. For example, when the value of the first indication information is 1, it instructs the first communication device to encode the second-level information in a non-segmented manner according to the Polar code encoding method. When the value of the first indication information is 0, it instructs the first communication device to segment the second-level information based on the third length, and encode the segmented second-level information according to the LDPC encoding method. For another example, when the value of the first indication information is 0, the first communication device encodes the second-level information in an LDPC encoding method, and the first communication device segments the second-level information based on the third length. When the value of the first indication information is 1, it instructs the first communication device to encode the second-level information in a non-segmented manner according to the Polar code encoding method.

[0373] Step b: The first communication device sends the second-level information to the second communication device. Correspondingly, the second communication device receives the second-level information from the first communication device.

[0374] The second-level information is generated according to the encoding method and / or segmentation method indicated by the first indication information.

[0375] Optionally, the second level information is transmitted on a shared channel. For example, the second level information is 2 nd -stage UCI, 2 nd -stage UCI is transmitted on PUSCH.

[0376] Step c: The second communication device determines a decoding method and / or a segmentation method of the second-level information according to the encoding method and / or segmentation method indicated by the first indication information.

[0377] In one possible implementation, the first indication information indicates an encoding method for the second-level information. If the first indication information indicates that the second-level information is encoded using a Polar code, the second communication device decodes the second-level information in a non-segmented manner according to a Polar decoding method. If the first indication information indicates that the second-level information is encoded using an LDPC encoding method, the second communication device segments the second-level information based on a third length and decodes the segmented second-level information according to an LDPC decoding method. For details about the third length, please refer to the relevant description of the embodiment shown in FIG. 4 .

[0378] In another possible implementation, the first indication information indicates the encoding method and segmentation method of the second-level information. If the first indication information indicates that the second-level information is non-segmented and encoded using the Polar code encoding method, then the second communication device decodes the second-level information in a non-segmented manner according to the Polar decoding method. If the first indication information indicates that the second-level information is segmented based on the third length and the second-level information is encoded using the LDPC encoding method, then the second communication device segments the second-level information based on the third length, and the second communication device decodes the segmented second-level information according to the LDPC decoding method. For the third length, please refer to the relevant introduction in the embodiment shown in Figure 4 above.

[0379] Optionally, this embodiment further includes step c1. Step c1 can be performed before step c.

[0380] Step c1: The first communication device sends the first-level information 2 to the second communication device. Correspondingly, the second communication device receives the first-level information 2 from the first communication device.

[0381] The first-level information 2 is used to decode the second-level information. Optionally, the first-level information 2 includes information about resources used to decode the second-level information. Specifically, the second communication device can parse the first-level information 2 to determine the time-frequency resource location occupied by the second-level information. The second communication device can receive the second-level information at the time-frequency resource location. For possible fields of the information used to decode the resources occupied by the second-level information, please refer to the relevant description in the embodiment shown in FIG. 4 , and will not be repeated here.

[0382] Optionally, the first-level information 2 does not include at least one of the following: shared channel indication, new data indication, redundant version, priority indication, HARQ process number, downlink allocation index, PDSCH to HARQ feedback timing, coding block transmission indication, coding block group refresh information, PDSCH group index, requested number of PDSCH groups, one-time HARQ request, new feedback indication, antenna port, transmission configuration indication TCI, sounding reference signal request, DMRS sequence initialization, or power control. The functions of these fields not included in the first-level information 2 can refer to the relevant introduction of the embodiment shown in Figure 4 above. This makes the first-level information 2 more streamlined, and the first-level information 2 is encoded in a non-segmented manner. The payload size of the first-level information 2 is further reduced, reducing the blind detection complexity of the second communication device.

[0383] Optionally, the length of the first-level information is less than or equal to the sixth length. For example, the sixth length is 70.

[0384] Optionally, the second level information includes T-MIMO CSI, perception-related information, artificial intelligence-related information, shared channel indication, new data indication, redundancy version, priority indication, HARQ process number, downlink allocation index, PDSCH to HARQ feedback timing, coding block transmission indication, coding block group refresh information, PDSCH group index, requested number of PDSCH groups, one-time HARQ request, new feedback indication, antenna port, transmission configuration indication TCI, sounding reference signal request, DMRS sequence initialization, or power control. It can be seen that the fields originally in the first level information 2 are moved to the second level information, thereby making the first level information 2 more streamlined.

[0385] The first-level information 2 and the second-level information correspond to the same service type, that is, the first-level information 2 and the second-level information are for the same service. That is, for the same service, the first communication device sends the first-level information 2 and the second-level information. Thus, the second communication device can parse the first-level information 2 to determine the time-frequency resource where the second-level information is located. Then, the second communication device can parse the second-level information to obtain the relevant data of the service. For example, the first-level information 2 is 1 st -stage UCI, the second level information is 2 nd -stage UCI.

[0386] After receiving the first-level information 2, the second communication device parses the first-level information 2 to obtain the resource location where the second-level information is located. The second communication device receives the second-level information through the resource location.

[0387] Optionally, the first-level information 2 is carried on at least one of the following: SR, HARQ-ACK, or CSI. The second-level information is carried on the intra RAN, sensing-related information, AI training information, and / or T-MIMO CSI, which is equal to control information with a larger payload size.

[0388] FIG5 is a schematic diagram of an embodiment of a method for sending first-level information according to an embodiment of the present application. Referring to FIG5 , the method includes:

[0389] 501. A first communication device determines first-level information.

[0390] The first-level information includes information about the resources used to decode the second-level information. In other words, the first-level information is used to decode the second-level information. This means that the second communication device can parse the first-level information to determine the resource location occupied by the second-level information. The second communication device can receive the second-level information at the resource location indicated by the first-level information. For information about the resources used to decode the second-level information, please refer to the description of the embodiment shown in FIG. 4 . The length of the first-level information is less than or equal to the first length. Optionally, the first length is 70.

[0391] Optionally, the first-level information does not include shared channel indication, new data indication, redundancy version, priority indication, HARQ process number, downlink allocation index, PDSCH to HARQ feedback timing, coding block transmission indication, coding block group refresh information, PDSCH group index, requested number of PDSCH groups, one-time HARQ request, new feedback indication, antenna port, transmission configuration indication TCI, sounding reference signal request, DMRS sequence initialization, or power control. The functions of these fields not included in the first-level information can refer to the relevant introduction of the embodiment shown in Figure 4 above. This makes the first-level information more streamlined, and the first-level information is encoded in a non-segmented manner. The payload size of the first-level information is further reduced, reducing the blind detection complexity of the second communication device.

[0392] Optionally, the first level information includes first level control information. For example, the first communication device is a terminal device, and the second communication device is a network device. The first level control information is first level uplink control information (1 st -stageUCI). For another example, the first communication device is a network device, and the second communication device is a terminal device. The first-stage control information is the first-stage downlink control information (1 st -stageDCI). For another example, the first communication device is a first terminal device, and the second communication device is a second terminal device. The first-stage control information is the first-stage sidelink control information (1 st -stageSCI).

[0397] In a possible implementation, the first communication device is a network device, and the second communication device is a terminal device. The first-level information is transmitted on a PDCCH and / or a PDSCH.

[0401] 503. The first communication device outputs the second level information.

[0402] Optionally, the first communication device sends the second-level information to the second communication device, and correspondingly, the second communication device receives the second-level information from the first communication device.

[0403] Specifically, the first-level information includes information about resources used to decode the second-level information. The second communication device determines the resource location of the second-level information based on the information about resources used to decode the second-level information. The second communication device then receives the second-level information at the resource location and decodes the second-level information.

[0404] Optionally, the second level information includes layer L1 information.

[0405] Optionally, the second level information includes at least one of the following: T-MIMO CSI, perception-related information, or AI training information.

[0406] Optionally, the second level information is transmitted on a shared channel.

[0407] In a possible implementation, the first communication device is a network device, and the second communication device is a terminal device. The second-level information is transmitted on a PDSCH.

[0408] In another possible implementation, the first communication device is a terminal device, and the second communication device is a network device. The second-level information is transmitted on a PUSCH.

[0409] In another possible implementation, the first communication device is a first terminal device, and the second communication device is a second terminal device. The second-level information is transmitted on the PSSCH.

[0410] It should be noted that in the several scenarios shown above, the second-level information is transmitted on a shared channel. Optionally, the second-level information can also be transmitted on a newly defined shared channel. For example, the corresponding shared channel is defined in combination with the type of service information carried by the second-level information, and the second-level information is transmitted on the newly defined shared channel. For example, the second-level information carries perception-related information, the newly defined shared channel can be called PSDSCH or PSUSCH, and the second-level information can be carried on PSDSCH or PSUSCH. For another example, the second-level information carries AI intelligent training data, and the newly defined shared channel can be called PADSCH or PAUSCH.

[0411] Optionally, the second level information includes second level control information. For example, the first communication device is a terminal device, and the second communication device is a network device. The second level control information is the second level uplink control information (2 nd -stageUCI). For another example, the first communication device is a network device, and the second communication device is a terminal device. The second-stage control information is the second-stage downlink control information (2 nd -stageDCI). For another example, the first communication device is a first terminal device, and the second communication device is a second terminal device. The second-stage control information is the second-stage sidelink control information (2 nd -stage SCI).

[0412] Optionally, the name of the second-level information can also be a newly defined name. For example, the second-level information carries perception-related information, and the second-level information can be called 2 nd -stage USI or 2 nd -stage DSI. For another example, the second-level information is carried in AI intelligent training data, and the second-level information can be called 2 nd -stageUAI or 2 nd -stage DAI.

For the functions of these fields included in the second-level information, please refer to the relevant introduction in the embodiment shown in Figure 4 above. It can be seen that the fields originally in the first-level information are moved to the second-level information, thereby making the first-level information more streamlined.

[0414] The first-level information and the second-level information correspond to the same service type, that is, the first-level information and the second-level information are for the same service. That is, for the same service, the first communication device sends the first-level information and the second-level information. This enables the second communication device to parse the first-level information and thereby determine the time-frequency resources where the second-level information is located. Then, the second communication device can parse the second-level information to obtain relevant data of the service. For example, for some specific communication scenarios, the name of the first-level information and the name of the second-level information can indicate that the first-level information and the second-level information are for the same service. For example, in the SL scenario, the first-level information is the first-level SCI, and the second-level information is the second-level SCI. For another example, the first-level information includes a second field, and the second field is used to indicate the service. For example, the second-level information carries perception-related information, and the first-level information includes a second field, and the second field indicates the perception service. It can be seen that both the first-level information and the second-level information are sent for the perception service.

[0415] In an embodiment of the present application, a first communication device determines first-level information, where the first-level information includes information about resources used to decode the second-level information, and the length of the first-level information is less than or equal to the first length; the first communication device transmits the first-level information. This makes the first-level information more concise, and the first-level information is encoded in a non-segmented manner. This further reduces the payload size of the first-level information, thereby reducing the blind detection complexity of the second communication device.
