Description

HARQ-ACK information transmission method and device

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for transmitting HARQ-ACK information.

Background

Hybrid Automatic Retransmission Request (HARQ) is a mechanism for improving the performance of a wireless communication system. In downlink data transmission, the application process of HARQ is: the base station firstly sends a data block to a certain user, the user checks after receiving the data block, and if the check is correct, the user sends confirmation information (ACK) to the base station; after receiving the ACK, the base station considers that the transmitted data block has been correctly received by the corresponding user, and then may transmit a new data block to the user. If the check is incorrect, the user will send a non-acknowledgement (NACK) message to the base station, and the base station will retransmit the sent data block to the user until the user feeds back an ACK after receiving correctly, or until the maximum number of retransmissions is exceeded.

When transmitting the ACK/NACK information (HARQ-ACK) based on HARQ, the ACK/NACK information may be transmitted based on Transport Blocks (TBs), and one TB corresponds to one bit of ACK/NACK feedback information for indicating whether the corresponding TB is received correctly; a certain transport Block may include a plurality of Code Block Groups (CBGs), and therefore, the transport Block may also be based on CBGs, where each CBG corresponds to one bit of ACK/NACK feedback information for indicating whether the corresponding CBG is correctly received. However, when the amount of HARQ-ACK information to be transmitted is large, it is inefficient to transmit directly for the TB or CBG.

Therefore, how to improve the transmission efficiency of the HARQ-ACK feedback information is a technical problem to be solved urgently at present.

Disclosure of Invention

The embodiment of the application provides a method and a device for transmitting HARQ-ACK information, which are used for improving the transmission efficiency of HARQ-ACK feedback information.

In a first aspect, a method for transmitting HARQ-ACK information is provided, where the method includes:

receiving a first instruction sent by network equipment, wherein the first instruction comprises an instruction used for instructing the terminal equipment to compress HARQ-ACK information;

compressing first HARQ-ACK information to obtain first information, wherein the first HARQ-ACK information is the HARQ-ACK information which needs to be compressed and is determined through the first instruction, and the first HARQ-ACK information comprises acknowledgement ACK information and/or non-acknowledgement NACK information of at least two bits;

and sending the first information to the network equipment.

In the embodiment of the application, when the terminal device sends HARQ-ACK feedback information for indicating whether data is successfully received to the network device, the network device may send a first instruction to the terminal device to indicate the terminal device to compress the HARQ-ACK information, so that the terminal device may determine, based on the instruction sent by the network device, HARQ-ACK information that needs to be compressed, then compress the HARQ-ACK information to obtain corresponding first information, and then send the compressed feedback information when sending the HARQ-ACK information to the network device.

In one possible design, the first instruction further includes an instruction for indicating a first number of bits, and the compressing the first HARQ-ACK information to obtain the first information includes:

performing equal-bit division on the first HARQ-ACK information according to the first bit quantity to obtain at least one divided HARQ-ACK packet;

determining second information corresponding to each HARQ-ACK packet in the at least one HARQ-ACK packet, wherein the second information corresponding to each HARQ-ACK packet is obtained after the each HARQ-ACK packet is compressed;

and obtaining the first information according to the second information corresponding to each HARQ-ACK grouping.

In this embodiment, the first instruction sent by the network device may further include an instruction for indicating the first bit number, and when performing compression processing on the corresponding HARQ-ACK information, the terminal device may perform equal-bit division on the HARQ-ACK information, that is, equally divide the HARQ-ACK information into several HARQ-ACK packets according to the first bit number, and then determine information obtained by compressing each HARQ-ACK packet, that is, second information, that is, perform compression processing on each HARQ-ACK packet, to obtain the second information of each HARQ-ACK packet, and then obtain the first information according to the second information of each HARQ-ACK packet, that is, obtain information obtained by compressing the original HARQ-ACK information. By compressing each HARQ-ACK packet respectively, the compression efficiency can be improved to a certain extent, the compression effectiveness is ensured, the final compression feedback information is obtained from the compressed information of each part, and the reliability of the final feedback information can also be ensured.

In a possible design, the second information corresponding to each HARQ-ACK packet is determined according to a first corresponding relationship, where the first corresponding relationship is a preset corresponding relationship between the HARQ-ACK packet and the second information, and the number of bits included in the second information corresponding to the HARQ-ACK packet with the higher occurrence probability in the HARQ-ACK packet included in the first corresponding relationship is smaller.

In the embodiment of the application, when the second information of each HARQ-ACK packet is determined, the second information may be determined directly according to a first corresponding relationship, where the first corresponding relationship includes a preset corresponding relationship between the HARQ-ACK packet and the second information, and the second information may be directly and simply determined through the first corresponding relationship. The higher the probability of occurrence of the HARQ-ACK packet in the first correspondence, the smaller the number of bits in the second information corresponding to the packet, so that the number of bits obtained after the compression processing is performed on the packet with the highest probability of occurrence in the HARQ-ACK information is smaller, thereby ensuring the effectiveness of compression.

In one possible design, the equal-bit dividing the first HARQ-ACK information according to the first number of bits to obtain at least one divided HARQ-ACK packet includes:

determining whether the number of bits included in the first HARQ-ACK information is an integer multiple of the first number of bits;

if not, obtaining third information according to the first HARQ-ACK information, wherein the bit number of the third information is integral multiple of the first bit number;

and performing equal-bit division on the third information according to the first bit quantity to obtain at least one divided HARQ-ACK packet.

In the embodiment of the application, before the HARQ-ACK information is divided, whether the HARQ-ACK information is integer multiples of the preset bit number or not needs to be determined, if not, some bits can be added to the HARQ-ACK information firstly, and the bit number included in the HARQ-ACK information is integer multiples of the preset bit number, so that the bit number included in each divided HARQ-ACK packet can be ensured to be the same, and the compressed HARQ-ACK information can be accurately acquired according to the second information of each HARQ-ACK packet.

In one possible design, obtaining the first information according to the second information corresponding to each HARQ-ACK packet includes:

if a difference exists between the second bit quantity and the third bit quantity, filling the second bit quantity to the third bit quantity, and determining the HARQ-ACK information filled to the third bit quantity as the first information.

In the embodiment of the present application, a fixed compression coding rate may be pre-agreed between the terminal device and the network device, so that, when the terminal needs to compress the HARQ-ACK information, it can be determined how many bits of data should be included in the compressed HARQ-ACK information when the terminal performs compression processing according to the preset compression coding rate, i.e. the third number of bits, then the terminal device performs the actual compression processing on the HARQ-ACK information to obtain the second information for each HARQ-ACK packet, summarizes each second information, i.e. the second number of bits comprised by the HARQ-ACK information actually subjected to the compression process can be obtained, then determining whether there is a difference between the second number of bits and the third number of bits, and if so, padding the second number of bits to the third number of bits, and then determining the filled HARQ-ACK information as the HARQ-ACK information obtained after final compression.

That is, the compression coding rate may be agreed between the terminal device and the network device, so as to set the number of bits after compression in advance, and if the number is found to be less than the target number of compressed bits after the compression processing is performed by the terminal device, bit padding may be performed, so that the number of bits included in the feedback information sent to the network device is the agreed number of bits in advance, thereby improving the effectiveness of feedback information transmission.

In one possible design, after obtaining the first information, the method further includes:

and sending fourth information to the network equipment so that the network equipment decompresses the first information according to the fourth information.

In this embodiment of the present application, the terminal device may further send compressed information during compression to the network device, that is, inform the network device of information such as a compression mode of compression performed by the terminal device itself, so that the network device may decompress the received feedback information according to the information to obtain actual feedback information, and then may learn an actual situation of receiving data by the terminal device, thereby determining whether to resend the data to the terminal device, or transmit new data of the information to the terminal device, and improving timeliness of data transmission.

In one possible design, the fourth information may include a first difference, a number of bits of the first HARQ-ACK information after compression processing, or a compression coding rate of the first HARQ-ACK information after compression processing; wherein the first difference is a difference between a number of bits included before the first HARQ-ACK information is compressed and a number of bits included after the first HARQ-ACK information is compressed.

In this embodiment, when the terminal device sends the compressed information for performing compression processing to the network device, the difference between the number of bits of the HARQ-ACK information before and after the compression processing may be sent to the network device, the number of bits included in the HARQ-ACK information after being compressed may be sent to the network device, or the compression coding rate for performing compression processing may be sent to the network device, and after receiving the information, the network device may perform decoding processing on the compressed feedback information according to the information to obtain the original feedback information. That is, the terminal device may send different compressed information to the network device, so that the flexibility of data transmission may be improved, and it may be ensured that the terminal device and the network device understand the compressed HARQ-ACK information consistently, thereby ensuring the reliability of information transmission.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. In the present application, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

Furthermore, the term "comprises" and any variations thereof, which are intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The "plurality" in the present application may mean at least two, for example, two, three or more, and the embodiments of the present application are not limited.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.

As described above, when transmitting the HARQ-ACK feedback information, the transmission may be performed based on the transport block TB, or may be performed based on the CBG. However, when the amount of HARQ-ACK information to be transmitted is large, it is inefficient to transmit directly for the TB or CBG.

In the related art, in order to reduce the size of the HARQ-ACK codebook, a New Radio (NR) supports an acknowledgment/non-acknowledgment (a/N) packing manner, for example, combining a/N feedback information of different transport blocks TB of a Physical Downlink Shared Channel (PDSCH) to obtain only one final a/N. However, when data of one of the transport blocks or transmission of the code block group CBG in one of the transport blocks is in error, it is considered that the PDSCH is not successfully received, and therefore, data of all TBs of the PDSCH needs to be retransmitted, resulting in low transmission efficiency.

In view of this, the present application provides a method for transmitting HARQ-ACK information, where when a terminal device needs to send HARQ-ACK feedback information to a network device, the network device may send a first instruction to the terminal device first, so that the terminal device compresses the HARQ-ACK information, and after determining the HARQ-ACK information that needs to be compressed according to the first instruction, the terminal device may compress the HARQ-ACK information, so that when the feedback information is actually sent, the compressed HARQ-ACK information may be sent as the first information.

In order to facilitate understanding of the technical solutions provided in the embodiments of the present application, some brief descriptions are provided below for application scenarios used in the technical solutions provided in the embodiments of the present application, and it should be noted that the application scenarios described below are only used for illustrating the embodiments of the present invention and are not limited. In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

Please refer to fig. 1, where fig. 1 is an application scenario to which the technical solution of the embodiment of the present application can be applied. In the application scenario shown in fig. 1, the terminal device 10 and the network device 11 are included, where the terminal device 10 may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, or the like. The network device 11 may be an access network device, a core network device, and the like, and the access network device may be a commonly used Base station, for example, an evolved Node Base station (eNB), and may also be a network side device in a 5G system (for example, a next generation Base station (gNB), a Transmission and Reception Point (TRP), a cell, and the like.

When the terminal device 10 receives a first instruction sent by the network device 11, the terminal device 10 may determine, according to the instruction, to perform compression processing on the HARQ-ACK information to be sent, then further determine, according to the first instruction, first HARQ-ACK information that needs to be compressed, and after compressing the first HARQ-ACK information, may obtain the first information, and then when the terminal device 10 sends the HARQ-ACK information to the network device 11, the first information after compression processing is sent, so as to effectively reduce the number of information bits to be transmitted, thereby improving the transmission efficiency of the feedback information. It should be noted that the HARQ-ACK information in the embodiment of the present application includes HARQ-ACK and HARQ-NACK.

To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figure when the method is executed in an actual processing procedure or a device.

Please refer to fig. 2, fig. 2 is a diagram illustrating a transmission method of HARQ-ACK information according to an embodiment of the present disclosure. The flow of the transmission method of HARQ-ACK information in fig. 2 is described as follows:

step 201: the network equipment sends a first instruction to the terminal equipment, wherein the first instruction comprises an instruction used for instructing the terminal equipment to compress the HARQ-ACK information.

In a specific implementation process, when the network device sends the PDSCH to the terminal device, the HARQ-ACK information sent by the terminal device to the network device may be understood as data used to indicate whether the terminal device successfully receives the PDSCH. It should be noted that the HARQ-ACK information may also be used to indicate whether other corresponding data is successfully received, for example, data of a Physical Downlink Control Channel (PDCCH), which is not limited in this embodiment of the application, and in the following embodiment, data of the HARQ-ACK information used to indicate whether a terminal device successfully receives a PDSCH is taken as an example for description.

In a possible implementation manner, when the terminal device needs to send HARQ-ACK feedback information to the network device, the network device may first send a first instruction to the terminal device to instruct the terminal device to perform compression processing on the HARQ-ACK information to be sent. That is, since HARQ-ACK information is compressed and then transmitted to the network device, all feedback information may be directly compressed and transmitted without performing a packet process on feedback information of different TBs or CBGs. It should be noted that, in a specific implementation process, the feedback information of different TBs or CBGs may be first subjected to a packet processing, then the feedback information with a smaller number of bits is obtained, and then the feedback information is subjected to a compression processing, and is sent, which is not limited in the embodiment of the present application.

In a possible implementation manner, when the network device sends the first instruction to the terminal device, the first instruction may be sent by using different sending manners, for example, the first instruction may be sent by using Downlink Control Information (DCI), or may be sent by using Media Access Control (MAC) signaling, or may be sent by using some other sending manner capable of issuing the first instruction, which is not limited herein.

It should be noted that when the first instruction is issued through DCI, HARQ-ACK information may be configured as a dynamic codebook for transmission, and this way may perform feedback based on the number of actually scheduled PDSCHs, which may reduce the number of redundant bits for feedback, and improve the efficiency of information transmission.

In a specific implementation process, the network device may determine whether the first instruction needs to be sent to the terminal device according to an actual situation, that is, the network device may send the first instruction to the terminal device only when a certain condition is met. For example, the network device may issue the first instruction to the terminal device only when the number of original HARQ-ACK information bits is greater than a certain threshold. For example, when the network device sends PDSCH data to the terminal device, it knows that a large amount of HARQ-ACK feedback information needs to be received, that is, the number of feedback information bits that need to be transmitted is large, and at this time, the network device may send a first instruction to the terminal device to instruct the terminal device to send the feedback information after compressing the feedback information.

It should be noted that, in any case, the network device may send the first instruction to the terminal device, that is, as long as the terminal device needs to send the feedback information, the network device issues the first instruction to the terminal device, so that the terminal device compresses the feedback information and then sends the compressed feedback information. And are not intended to be limiting herein.

Step 202: the terminal equipment receives a first instruction sent by the network equipment.

In a specific implementation manner, when the terminal device receives the first instruction sent by the network device, it indicates that the HARQ-ACK information needs to be compressed, that is, the terminal device knows that the HARQ-ACK information needs to be compressed.

Step 203: the terminal equipment compresses the first HARQ-ACK information to obtain first information, the first HARQ-ACK information is the HARQ-ACK information which needs to be compressed and is determined through a first instruction, and the first HARQ-ACK information comprises acknowledgement ACK information and/or non-acknowledgement NACK information of at least two bits.

In a possible implementation manner, after receiving the first instruction, the terminal device may know that the HARQ-ACK information is to be compressed, and at the same time, the first instruction further includes specific indication information indicating which part of the HARQ-ACK information is to be compressed by the terminal device. In a specific implementation process, the plurality of bit information included in the first HARQ-ACK information may include only ACK information, may also include NACK information, or may include both ACK information and NACK information, which is not limited herein.

In a possible implementation manner, when compressing the first HARQ-ACK information, all bits included in the first HARQ-ACK information may be compressed at the same time, that is, it may be implemented between the terminal device and the network device which compression coding method is used to compress and encode the feedback information, and then after receiving the first instruction sent by the network device, the terminal compresses the feedback information according to the preset coding method to obtain the compressed feedback information.

In another possible implementation, the first HARQ-ACK information may be divided first, then a plurality of divided HARQ-ACK packets are obtained, and during compression, each HARQ-ACK packet is compressed, so as to obtain a result of compressing each packet, for example, the result may be referred to as second information corresponding to each packet, and then feedback information (i.e., first information) that needs to be finally sent is obtained according to the second information corresponding to each packet.

In a specific embodiment, the first HARQ-ACK information may be subjected to equal-bit division, for example, the HARQ-ACK information may be subjected to equal-bit grouping according to a first number of bits, where the first number of bits may be carried in a first instruction, that is, the first instruction sent by the network device further includes an instruction for indicating the first number of bits, so that the terminal device divides the first HARQ-ACK information according to the first number of bits, and then compresses each HARQ-ACK packet obtained by the division. It should be noted that the first number of bits may also be sent to the terminal device by another instruction, that is, after sending the first instruction to the terminal, the network device sends a new instruction to the terminal again to indicate the first number of bits. The embodiments of the present application are not limited. The first number of bits may be, for example, 4 bits or 8 bits, and the like, and of course, may also be any number of bits, and this embodiment of the present application is not limited, but for convenience of compression encoding and decompression encoding, generally, division may be performed by 4 bits, or division may be performed by 8 bits.

For example, the HARQ-ACK information includes bit data of "1111010111100111", where "1" indicates an ACK bit and "0" indicates a NACK bit, and the division by 4 bits results in "1111", "0101", "1110", and "0111", and the division by 8 bits results in "11110101" and "11100111". And then, respectively carrying out compression coding on the obtained HARQ-ACK groups, and then summarizing the HARQ-ACK groups to obtain final first information. For example, 4 packets divided by 4 bits are respectively "10", "0100", "0110", and "111" after compression coding, and then the finally obtained first information is "1001000110111".

In a possible embodiment, before performing equal-bit division on the first HARQ-ACK information, it may be determined whether the number of bits included in the first HARQ-ACK information is an integer multiple of a preset number of bits (i.e., the first number of bits), and in the case of yes, the first HARQ-ACK information may be directly subjected to equal-bit division, and if it is determined that the number of bits included in the first HARQ-ACK information is not the integer multiple of the first number of bits, the number of bits included in the first HARQ-ACK information needs to be padded to be added to the integer multiple of the first number of bits, and then the added HARQ-ACK information is obtained, which may be referred to as third information, for example.

It should be noted that, when adding the first HARQ-ACK information, all bits may be added as "1" bits, or all bits may be added as "0" bits, and when adding is needed, specifically, what bit is added may be a good agreement between the terminal device and the network device in advance. Then after the addition to obtain the third information, the third information may be equally bit divided to obtain a plurality of HARQ-ACK packets.

For example, if the first HARQ-ACK information is "1110110", and then is divided according to 4 bits, and the HARQ-ACK information includes 7 bits, then a bit addition process is required, for example, the terminal device and the network device agree that the bit addition process is performed through "1" bit, then after the addition process is performed on the first HARQ-ACK information, the obtained third information is "11101101", and after the third information is divided, two HARQ-ACK packets, which are "1110" and "1101", respectively, are obtained.

In a possible implementation manner, when the second information corresponding to each HARQ-ACK packet is obtained, the determination may be performed according to a correspondence between the HARQ-ACK packet and the second information, and for convenience of description, for example, the correspondence may be referred to as a first correspondence. That is, the network device or the terminal device may determine in advance, based on some preset rules, the correspondence between some HARQ-ACK packets and the second information, and then store the correspondence, and when determining the second information, may determine which HARQ-ACK packet belongs to which HARQ-ACK packet in the first correspondence, and then determine which information the second information corresponding to the HARQ-ACK packet belongs to according to the first correspondence, thereby obtaining the second information of each HARQ-ACK packet.

In a possible implementation manner, the first corresponding relationship may be obtained by performing statistics on a plurality of sample data, may be obtained by performing statistics on a network device, or may be obtained by performing statistics on a terminal device, which is not limited herein. That is, some sample data may be acquired, the sample data may be divided into bit groups of different bit lengths, then the probability of occurrence of the bit group in each division manner is determined, and the first correspondence relationship is determined according to the determined probability. The specific determination method may be a bit group with high occurrence probability, and the number of bit groups obtained after compression encoding is smaller, so that the compression effectiveness can be improved. Then, by performing division statistics on the sample data with different bit lengths, a plurality of corresponding first corresponding relations can be obtained, and when the second information needs to be determined through the first corresponding relations, the first corresponding relation which best meets the actual situation can be determined from the plurality of first corresponding relations.

It should be noted that, when performing sample training statistics, the sample training may be performed based on a target block error rate (Bler), and a value of the target Bler may represent ratio information of ACK and NACK included therein, and performing sample statistics according to the information may ensure that the obtained first corresponding relationship may accurately determine the second information of each HARQ-ACK packet.

In a specific embodiment, when Bler is less than or equal to 10%, that is, the number of ACK bits is much greater than the number of NACK bits, lossless data compression may be performed on HARQ-ACK information, and after the compressed data is reconstructed by the lossless data compression, the reconstructed data is completely consistent with the original data, so that the network device may obtain complete HARQ-ACK feedback information.

In a specific embodiment, the first corresponding relationship may be stored in a table or a manner describing a document. For example, the first correspondence relationship may be as shown in table 1, where table 1 is a first correspondence relationship set for a case where the number of ACK bits is much larger than the number of NACK bits. It should be noted that table 1 is only an example, in table 1, 4 bits are divided into examples, in table 1, the original a/N bits are bit combination information before compression processing, and the compression coding is bit combination information after compression processing, that is, second information corresponding to each original HARQ-ACK bit packet.

TABLE 1

Each entry in table 1 may be considered as a corresponding relationship, for example, after division, bit data corresponding to a certain HARQ-ACK packet is "1111", and then it can be determined through the corresponding relationship in table 1 that the corresponding bit data after compression coding should be "10", that is, the second information corresponding to the "1111" packet is "10". Of course, the corresponding relationship may also be in other expression forms, which are not illustrated herein, and the expression form of the corresponding relationship is not limited in this embodiment of the application.

Note that, in table 1, the probability of occurrence of a bit combination including a large number of ACK bits is the highest when performing statistics, and therefore the number of bits included in a corresponding combination after compression encoding is the smallest. Therefore, table 1 is applicable to feedback information in which ACK bits are much more than NACK bits, so that the compression effectiveness can be ensured after compression encoding.

In one possible embodiment, table 1 may be applied to Enhanced Mobile Broadband (eMBB) service or Low-Latency high-reliability Communication (URLLC) service, in the eMBB service, the value of the target Bler is generally set to 10%, that is, the ratio of ACK to NACK included in the feedback information is not less than 9:1, and in the URLLC service, the value of the target Bler is generally set to less than 1%, that is, the ratio of ACK to NACK included in the feedback information is not less than 99:1, that is, the number of ACKs is much greater than the number of NACKs. Therefore, in these two scenarios, each HARQ-ACK packet is compressed and encoded by using the corresponding relationship in table 1, and the finally obtained first information contains a smaller number of bits, so that the transmission effectiveness can be improved. Of course, the corresponding relationship in table 1 may also be used in other services in which the number of ACK bits is much greater than that of NACK bits, and is not limited herein.

That is, compression processing is performed according to the first correspondence shown in table 1, and when compression is actually performed, considering that the number of ACK bits is much greater than that of NACK, the HARQ-ACK packet including the larger number of ACK bits is compressed into the smaller number of bits, so that compression efficiency is improved, and transmission efficiency of feedback information is also improved.

Referring to table 2, table 2 shows the compression code rate after compression coding of some original HARQ-ACK bit data when the target Bler is 10% and the ratio of ACK to NACK is equal to 9:1, where the data in table 2 corresponds to the first corresponding relationship shown in table 1, specifically, the second information of each HARQ-ACK packet is determined according to the first corresponding relationship shown in table 1, then the first information is determined according to the second information, and finally the data shown in table 2 is obtained by calculation through the second information and the first information.

TABLE 2

As can be seen from table 2, after compressing the HARQ-ACK information according to the first corresponding relationship in table 1, the number of bits of the feedback information that needs to be transmitted in the transmission process can be effectively reduced, thereby improving the transmission efficiency of the feedback information.

In a possible implementation, the first corresponding relationship may also be determined according to historical data, that is, the network device may set a specific target Bler, determine a bit combination with the highest probability of being transmitted from the historical HARQ-ACK data satisfying the target Bler, and set the bit combination as the least number of bits corresponding to the compressed code, thereby obtaining a compressed code table (i.e., the first corresponding relationship).

As an example, the first correspondence obtained from the history data is shown in table 3, the compression coding in table 3 may be obtained by huffman coding, and the same understanding can be given to table 3 by referring to the description of table 1, which is not described herein again. It should be noted that, in a specific implementation process, the first corresponding relationship obtained through the historical data may be determined as a default corresponding relationship, that is, when the first corresponding relationship is obtained without performing training statistics according to sample data, the second information of each HARQ-ACK packet may be directly determined according to the default corresponding relationship.

TABLE 3

Original A/N bits	Compression coding
		1111	10
1011	111
		1101	110
0111	0111
		1110	0110
0011	0101
		0101	0100
0110	0010
		1001	00111
1010	00110
		1100	000111
0100	000110
		0010	000101
0001	000100
		1000	000010
0000	000000

Of course, the corresponding relationship may also be in other expression forms, which are not illustrated herein, and the expression form of the corresponding relationship is not limited in the embodiment of the present application.

In a specific implementation process, after the second information corresponding to each HARQ-ACK packet is obtained, the second information may be summarized and sent to the network device as the final first information, or the summarized second information may be sent to the network device after being processed to some extent.

In one possible implementation, for example, the target compression coding rate is predetermined in advance between the terminal device and the network device, and may be referred to as a first compression coding rate, for example, when the terminal device transmits the feedback information to the network device, the number of bits included in the transmitted feedback information should be the number of bits compressed according to the first compression coding rate, and for convenience of distinguishing, the number of bits included after the HARQ-ACK information is compressed by the first compression coding rate may be referred to as a third number of bits, for example. However, after the actual compression processing, there may be a difference between the obtained number of bits and the third number of bits, for example, the actually obtained number of bits may be referred to as the second number of bits, in which case, the second number of bits may be padded to the third number of bits before being transmitted.

In a specific implementation process, after obtaining second information corresponding to each HARQ-ACK packet, a total number of bits (i.e., a second number of bits) included in all the second information may be determined, then it is determined how many bits of information are included in the information obtained after compression if the first HARQ-ACK information is compressed at the first compression coding rate, that is, it is determined that a third number of bits is included, then it is determined whether a difference exists between the second number of bits and the third number of bits, if it is determined that the difference exists, the obtained second number of bits in the HARQ-ACK information is filled to the third number of bits, and then the HARQ-ACK information filled to the third number of bits is determined to be the first information that needs to be finally sent.

It should be noted that the first compression coding rate is generally higher than the lowest coding rate to ensure that the redundant bits can be filled, and therefore, the third number of bits obtained by performing the compression processing on the first compression coding rate is generally greater than or equal to the second number of bits, and therefore, when performing the filling processing on the second number of bits, it can be understood that a certain number of bits is increased to make the second number of bits equal to the third number of bits.

In a specific embodiment, before padding the second number of bits, a difference between the third number of bits and the second number of bits may be determined, and then padding processing may be performed on the third number of bits according to the difference. In a specific implementation, if the difference is 1, then the bit "1" may be complemented after the third number of bits, and if the difference is greater than 1, then the bit "1" may be complemented with a plurality of combined bits "10" until only one bit is differed. It should be noted that, only a specific example is given here, and the filling process may also be performed by other ways, which is not limited here.

As shown in table 4, table 4 shows the number of bits included in some typical HARQ-ACK information after compression when the ratio of ACK to NACK is greater than or equal to 9:1 when the target compression coding rate (i.e., the first compression coding rate) is 75%.

TABLE 4

The process of padding the second number of bits is explained below by a specific example. Assuming that the first HARQ-ACK information includes 32 bits of data, if the target compression ratio of 75% in table 3 is taken as an example, the first information actually transmitted to the network device should include 24 bits of data (i.e., the third number of bits), but the terminal device may include only 23 bits of data (i.e., the second number of bits) after actually performing compression, that is, there is a difference between the second number of bits and the third number of bits, and the difference is 1, and then the information is transmitted to the network device after the 23 bits are filled with bit "1"; or the actual compressed data includes 22 bits, and the difference between the second bit quantity and the third bit quantity is 2, then the bit combination "10" is filled behind the 22 bits, and then the data is sent as the first information; or actually compressed, includes 21 bits of data, and the difference between the second bit number and the third bit number is 3, then the bit combination "10" needs to be filled after the 21 bits, then the bit "1" needs to be filled, and finally the first information is sent.

In a possible implementation manner, after obtaining the first information, the terminal device may send, to the network device, compressed information when performing the compression processing, for example, the compressed information may be referred to as fourth information, where the fourth information is used to indicate how the terminal device compresses the HARQ-ACK information, so as to ensure that the terminal device and the network device understand the same HARQ-ACK information after compression, that is, the network device may perform correct decompression processing on the received first information according to the fourth information, so as to obtain complete HARQ-ACK feedback information before compression.

In a possible implementation manner, the fourth information sent by the terminal device may be a difference between the number of bits before the first HARQ-ACK information is compressed and the number of bits after the first HARQ-ACK information is compressed, for example, the difference may be referred to as a first difference, and this method may also be understood as that the terminal device feeds back the compressed information to the network device through a separate message, and after receiving the first difference, the network device may determine the number of compressed bits according to the first difference, and then decompress the compressed HARQ-ACK information (i.e., the first information).

Or the fourth information sent by the terminal device may be the bit number included after the first HARQ-ACK information is compressed, and this method may also be understood as that the terminal device informs the network device of the compressed information in an explicit manner, so that the network device decompresses the first information according to the bit number; or the fourth information sent by the terminal device may also be an actual compression coding rate when the first HARQ-ACK information is compressed, and this method may also be understood as that the terminal device informs the network device of the compressed information in an implicit manner, so that the network device determines the number of compressed bits according to the compression coding rate, and then decompresses the first information.

It should be noted that the fourth information may be included in the first information, that is, the first information sent by the terminal device to the network device includes both the compressed HARQ-ACK information and the compressed information during the compression processing, so that after receiving the first information, the network device decompresses the compressed HARQ-ACK information according to the fourth information included therein. Or, the fourth information may also be sent separately, that is, after the first information is obtained, the terminal device may send the fourth information to the network device separately, and notify the network device of the specific compression processing manner, and as for the manner of sending the fourth information, the embodiment of the present application is not limited.

Step 204: the terminal device sends the first information to the network device.

In a specific implementation manner, after obtaining the first information, the terminal device may send the first information to the network device, that is, send compressed HARQ-ACK information to the network device, so that the transmission amount of information may be reduced, and the transmission efficiency of HARQ-ACK information may be improved.

Step 205: the network equipment receives first information sent by the terminal equipment.

In a specific embodiment, after receiving the first information sent by the terminal device, the network device may perform decompression processing on the first information, and specifically, may perform decompression processing according to the foregoing fourth information. When the network device decompresses the first information, it can obtain complete HARQ-ACK feedback information, and then determines whether the terminal device successfully receives the corresponding data according to the decompressed HARQ-ACK information, and when the terminal device does not successfully receive the corresponding data, it can resend the corresponding data to the terminal device.

The process of the terminal device performing compression coding on the HARQ-ACK feedback information and the network device performing corresponding decompression coding is further described with reference to fig. 3. Referring to fig. 3, at the terminal device side, the terminal device first compresses HARQ-ACK information, then performs Code Block Cyclic Redundancy Check (CB-CRC) on the compressed HARQ-ACK codebook, then performs coding by using a corresponding Polar Code, then performs rate matching, then performs interleaving processing, and finally performs transmission.

Correspondingly, when receiving the compressed HARQ-ACK information, the network equipment performs deinterleaving processing, then performs de-rate matching processing, then performs Polar code decoding, and finally performs CRC (cyclic redundancy check) processing, so as to obtain the original HARQ-ACK feedback information. The specific processes can be understood by referring to the related art, and are not described in detail herein.

In the embodiment of the application, when the terminal device needs to send HARQ-ACK feedback information to the network device, the network device may send a first instruction to the terminal device first, so that the terminal device compresses the HARQ-ACK information, and after determining the HARQ-ACK information that needs to be compressed according to the first instruction, the terminal device may compress the HARQ-ACK information, so that when the feedback information is actually sent, the compressed first information is sent.
