Description

HARQ-ACK information transmission method and device

Technical Field

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

Background

Hybrid automatic repeat request (Hybrid Automatic Retransmission Request, HARQ) is one mechanism to improve the performance of wireless communication systems. During downlink data transmission, the application process of the HARQ is as follows: the base station firstly transmits a data block to a certain user, the user checks after receiving the data block, and if the data block is checked correctly, the base station transmits determination 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 can transmit a new data block to the user. If the verification is incorrect, the user will send non-acknowledgement (NACK) to the base station, and the base station will retransmit the data block sent to the user until the user receives the ACK correctly, or until the maximum number of retransmissions is exceeded.

When transmitting ACK/NACK information (HARQ-ACK) based on HARQ, it may be based on Transport Block (TB), and then 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), so that transmission may be performed based on CBGs, where each CBG corresponds to one bit of ACK/NACK feedback information to indicate whether the corresponding CBG is received correctly. However, when the amount of HARQ-ACK information to be transmitted is large, the efficiency of transmission directly for the TB or CBG is low.

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

Disclosure of Invention

The embodiment of the application provides a transmission method and a transmission device of 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, the method comprising:

receiving a first instruction sent by network equipment, wherein the first instruction comprises an instruction 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 HARQ-ACK information which is determined to be compressed through the first instruction, and the first HARQ-ACK information comprises at least two bits of acknowledgement ACK information and/or non-acknowledgement NACK information;

and sending the first information to the network equipment.

In the embodiment of the present application, when the terminal device is to send the HARQ-ACK feedback information for indicating whether to successfully receive data 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, so that the terminal device may determine, based on the instruction sent by the network device, the HARQ-ACK information that needs to be compressed, and then perform compression processing on the HARQ-ACK information to obtain corresponding first information, and then when the HARQ-ACK information is sent to the network device, the feedback information after compression processing may be sent, so that when the feedback information that is sent is relatively more, the code rate may be effectively reduced, and the transmission efficiency of the feedback information may be improved, and further the reliability of HARQ-ACK information transmission may be improved.

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;

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

In this embodiment, the first instruction sent by the network device may further include an instruction for indicating the first bit number, where the terminal device may first perform equal bit division on the corresponding HARQ-ACK information when performing compression processing on the HARQ-ACK information, that is, divide the HARQ-ACK information into several HARQ-ACK packets according to the first bit number, and then determine compressed information, that is, second information, of each HARQ-ACK packet, that is, perform compression processing on each HARQ-ACK packet, to obtain second information of each HARQ-ACK packet, and then obtain first information according to the second information of each HARQ-ACK packet, that is, obtain compressed information of the original HARQ-ACK information. By compressing each HARQ-ACK packet, 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 be ensured.

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

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

In one possible design, the equally bit-dividing the first HARQ-ACK information by the first number of bits to obtain the divided at least one 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 an integer 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 present invention, before dividing the HARQ-ACK information, it needs to determine whether the HARQ-ACK information is an integer multiple of the preset number of bits, if not, some bits may be added to the HARQ-ACK information first, so that the number of bits included in the HARQ-ACK information is an integer multiple of the preset number of bits, so that the number of bits included in each divided HARQ-ACK packet is ensured to be the same, and thus the compressed HARQ-ACK information can be effectively and accurately obtained according to the second information of each HARQ-ACK packet.

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

and if the second bit number and the third bit number have a difference value, filling the second bit number to the third bit number, and determining the HARQ-ACK information filled to the third bit number as the first information.

In this embodiment, a fixed compression coding rate may be pre-agreed between the terminal device and the network device, so when the terminal needs to perform compression processing on the HARQ-ACK information, it may be determined how many bits of data, that is, the third number of bits, should be included in the compressed HARQ-ACK information when compression processing is performed according to the preset compression coding rate, then the terminal device performs actual compression processing on the HARQ-ACK information to obtain second information for each HARQ-ACK packet, and all the second information is summarized, so that the second number of bits included in the HARQ-ACK information actually subjected to compression processing may be obtained, then it is determined whether a difference exists between the second number of bits and the third number of bits, if the difference exists, the second number of bits is filled into the third number of bits, and then the filled HARQ-ACK information is determined to be the HARQ-ACK information obtained after final compression.

That is, the compression coding rate may be defined between the terminal device and the network device, so that the number of compressed bits is set in advance, and if the number of bits found by the terminal device after the compression processing is less than the target number of compressed bits, bit filling may be performed, so that the number of bits included in the feedback information sent to the network device, that is, the number of bits defined in advance, improves the effectiveness of the 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 can decompress the first information according to the fourth information.

In the embodiment of the application, the terminal device may also send the compressed information during the compression processing to the network device, that is, inform the network device of the compression manner and other information of the compression processing performed by the terminal device, so that the network device may perform decompression processing on the received feedback information according to the information, thereby obtaining actual feedback information, and then may know the actual condition of the terminal device receiving the data, 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 includes a first difference value, a number of bits after the first HARQ-ACK information is compressed, or a compression coding rate for the first HARQ-ACK information; the first difference value is a difference value between the number of bits included before the first HARQ-ACK information is compressed and the number of bits included after the first HARQ-ACK information is compressed.

In this embodiment of the present application, when the terminal device sends compressed information during compression processing to the network device, the terminal device may send the difference between the number of bits of the HARQ-ACK information before compression processing and the number of bits of the HARQ-ACK information after compression processing to the network device, or may send the number of bits included after compression processing to the network device, or may send the compression encoding rate during compression processing to the network device, and after the network device receives these information, the network device may decode the compressed feedback information according to these information, so as 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

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. Embodiments and features of embodiments in this application may be combined with each other arbitrarily without conflict. Also, while a logical order is depicted in the flowchart, in some cases, the steps depicted or described may be performed in a different order than presented herein.

Furthermore, the term "include" and any variations thereof is 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 listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. The term "plurality" in the present application may mean at least two, for example, two, three or more, and embodiments of the present application are not limited.

In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. The character "/" herein generally indicates that the associated object is an "or" relationship unless otherwise specified.

As described above, the HARQ-ACK feedback information may be transmitted on the basis of the transport block TB or on the basis of the CBG. However, when the amount of HARQ-ACK information to be transmitted is large, the efficiency of transmission directly for the TB or CBG is low.

In the related art, to reduce the HARQ-ACK codebook size, new Radio (NR) supports a method of using acknowledgement/non-acknowledgement (a/N) packing, for example, combining a/N feedback information of different transport blocks TB of a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) to obtain only one final a/N. However, when data of a certain transport block or transmission of a code block group CBG in a certain transport block is wrong, it is considered that PDSCH is not successfully received, and therefore, retransmission of data of all TBs of PDSCH is required, resulting in lower transmission efficiency.

In view of this, the application provides a transmission method of HARQ-ACK information, by which, 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 after determining, according to the first instruction, the HARQ-ACK information that needs to be compressed, so that when feedback information is actually sent, the terminal device may send the compressed first information, and when the feedback information is sent more, it may not need to package feedback information of different TBs or CBGs, and also may effectively reduce the number of transmitted information bits, thereby improving the transmission efficiency of HARQ-ACK information.

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

Referring to fig. 1, fig. 1 is an application scenario to which the technical solution of the embodiment of the present application may 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, or the like, and the access network device may be a commonly used base station, for example, an evolved base station (evolved Node Base station, eNB), or a network side device (for example, a next generation base station (next generation Node Base station, gNB) or a device for transmitting and receiving a point (Transmission and Reception Point, TRP) or a cell in a 5G system.

When the terminal device 10 receives the first instruction sent by the network device 11, the terminal device 10 can determine that the transmitted HARQ-ACK information is to be compressed according to the instruction, then further determine the first HARQ-ACK information to be compressed according to the first instruction, after compressing the first HARQ-ACK information, the first information can be obtained, and then when the terminal device 10 sends the HARQ-ACK information to the network device 11, the compressed first information is sent, so that the number of transmitted information bits is effectively reduced, and the transmission efficiency of feedback information is improved. Note that, the HARQ-ACK information in the embodiment of the present application includes two types of HARQ-ACK and HARQ-NACK.

In order to further explain the technical solutions provided in the embodiments of the present application, the following details are described with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operational steps as shown in the following embodiments or figures, more or fewer operational steps may be included in the method, either on a routine or non-inventive basis. In steps where there is logically no necessary causal relationship, the execution order of the steps is not limited to the execution order provided by the embodiments of the present application. The methods may be performed sequentially or in parallel as shown in the embodiments or the drawings when the actual processing or the apparatus is performed.

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

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

In a specific implementation process, when the network device sends PDSCH to the terminal device, the HARQ-ACK information sent by the terminal device to the network device may be understood as data for indicating whether the terminal device successfully receives PDSCH. Note that, the HARQ-ACK information may also be data for indicating whether other corresponding data is successfully received, for example, data of a physical downlink control channel (Physical downlink control channel, PDCCH), which is not limited in the embodiments of the present application, and in the following embodiments, the HARQ-ACK information will be described by taking data for indicating whether the terminal device successfully receives the PDSCH as an example.

In one 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 HARQ-ACK information to be sent. That is, since the HARQ-ACK information is compressed and then transmitted to the network device, it is possible to directly compress and transmit all feedback information without packing feedback information of different TBs or CBGs. It should be noted that, in a specific implementation process, feedback information of different TBs or CBGs may be obtained after being packaged, and then compressed, and then transmitted, where the embodiment of the present application is not limited.

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 a different sending manner, for example, may be sent by downlink control information (Downlink Control Information, DCI), or may be sent by media access control, MAC (Media Access Control, MAC) signaling, or may be sent by some other sending manner capable of sending the first instruction, which is not limited herein.

When the first instruction is issued through the MAC, the HARQ-ACK information is configured into a semi-static codebook for transmission, the semi-static codebook is determined based on the semi-static configuration, the problem that the network equipment and the terminal are inconsistent in understanding the size of the codebook due to missing detection of the DCI can be avoided, and reliability is ensured.

In a specific implementation process, the network device may determine, according to an actual situation, whether to send the first instruction to the terminal device, that is, if a certain condition is met, the network device will send the first instruction to the terminal device. 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 is already known 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, if the terminal device needs to send the feedback information, the network device sends the first instruction to the terminal device, so that the terminal device compresses the feedback information and then sends the feedback information. There is no limitation in this regard.

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

In a specific embodiment, 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 first HARQ-ACK information to obtain first information, wherein the first HARQ-ACK information is the HARQ-ACK information which is determined to be compressed through a first instruction, and the first HARQ-ACK information comprises at least two bits of Acknowledgement (ACK) information and/or non-acknowledgement (NACK) information.

In a possible implementation manner, after the terminal device receives the first instruction, it may learn that the HARQ-ACK information is to be compressed, and meanwhile, the first instruction further includes specific indication information, which part of the HARQ-ACK information is to be compressed by the terminal device, for convenience of description, for example, the part of the HARQ-ACK information may be referred to as first HARQ-ACK information, that is, the terminal device may determine the first HARQ-ACK information based on the first instruction. The first HARQ-ACK information includes at least two bits of ACK information and/or NACK information, and in a specific implementation process, the plurality of bits of information included in the first HARQ-ACK information may include only ACK information, may refer to including NACK information, or may include both ACK information and NACK information, which is not limited herein.

In a possible implementation manner, when the first HARQ-ACK information is compressed, all bits included in the first HARQ-ACK information may be compressed at the same time, that is, a rule may be implemented between the terminal device and the network device that the compression coding mode is used to compress and code the feedback information, and then after receiving the first instruction sent by the network device, the terminal compresses the feedback information according to a preset coding mode, so as to obtain compressed feedback information, and for convenience of description, for example, the compressed feedback information may be referred to as first information.

In another possible implementation manner, the first HARQ-ACK information may be divided first, then a plurality of divided HARQ-ACK packets are obtained, and when compression is performed, each HARQ-ACK packet is compressed to obtain a result after each packet is compressed, for example, the result may be referred to as second information corresponding to each packet, and then feedback information (i.e., the 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 equally bit-divided, for example, the HARQ-ACK information may be equally bit-grouped 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 division. It should be noted that the first number of bits may also be sent to the terminal device by other instructions, i.e. after sending the first instruction to the terminal, the network device sends a new instruction to the terminal again, indicating 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, or the like, and of course, any number of bits may be used, which is not limited in the embodiment of the present application, but in order to facilitate compression encoding and decompression encoding, it is generally selected to divide by 4 bits or divide by 8 bits.

For example, the HARQ-ACK information includes bit data of "1111010111100111", where "1" represents an ACK bit, "0" represents a NACK bit, and the results obtained after dividing by 4 bits are "1111", "0101", "1110" and "0111", and the results obtained after dividing by 8 bits are "11110101" and "11100111", for example. 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, after 4 packets are divided by 4 bits, the compression codes are respectively "10", "0100", "0110" and "111", and the first information finally obtained is "1001000110111".

In one possible implementation manner, before the first HARQ-ACK information is subjected to the equal bit division, it may be determined whether the number of bits included in the first HARQ-ACK information is an integer multiple of the preset number of bits (i.e., the first number of bits), in which case the first HARQ-ACK information may be directly subjected to the equal bit division, and if it is determined that the number of bits included in the first HARQ-ACK information is not an integer multiple of the first number of bits, it is necessary to perform the padding process on the number of bits included in the first HARQ-ACK information to add the same to the integer multiple of the first number of bits, and then obtain the added HARQ-ACK information, which may be referred to as third information, for example.

When the first HARQ-ACK information is added, all the bits may be added to "1" bits, or all the bits may be added to "0" bits, and when the addition is required, the specific addition of the bits may be that the terminal device and the network device have a protocol in advance. Then after the adding to obtain the third information, the third information may be equally bit-divided to obtain a plurality of HARQ-ACK packets.

For example, the first HARQ-ACK information is "1110110", and then is divided according to 4 bits, and at this time, the HARQ-ACK information includes 7 bits, so that it is required to perform processing of adding bits, for example, the terminal device and the network device agree to perform adding processing through "1" bits, and then the third information obtained after adding processing the first HARQ-ACK information is "11101101", and after dividing the third information, two HARQ-ACK packets are obtained, which are "1110" and "1101", respectively.

In one possible implementation manner, when the second information corresponding to each HARQ-ACK packet is acquired, the determination may be made 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, a correspondence between some HARQ-ACK packets and the second information based on some preset rules, and then store the predetermined correspondence, and when determining the second information, determine which HARQ-ACK packet in the first correspondence belongs to a certain HARQ-ACK packet, and then determine, according to the first correspondence, which second information corresponding to the certain HARQ-ACK packet is which information, so as to obtain the second information of each HARQ-ACK packet.

In a possible implementation manner, the first correspondence may be obtained by counting a number of sample data, may be counted by the network device, or may be counted by the terminal device, and 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, and then the probability of occurrence of the bit groups in each division manner may be determined, and the first correspondence may be determined according to the determined probability. The specific determination method can be bit groups with high occurrence probability, and the number of the bit groups obtained after compression encoding is smaller, so that the compression effectiveness can be improved. Then, through carrying out dividing statistics on different bit lengths on the sample data, a plurality of corresponding first corresponding relations can be obtained, and when second information needs to be determined through the first corresponding relations, a first corresponding relation which is most in line with the actual situation can be determined from the plurality of first corresponding relations.

It should be noted that, when the sample training statistics are performed, the sample training may be performed based on a target block error rate (Bler), the value of the target Bler may represent the proportion information of ACK and NACK included in the sample training statistics, and the sample statistics may be performed according to the proportion information, so that it may be ensured that the obtained first correspondence relationship may accurately determine the second information of each HARQ-ACK packet.

In a specific embodiment, when the number of the Bler is less than or equal to 10%, that is, the number of the ACK bits is far more than the number of the NACK bits, lossless data compression processing may be performed on the HARQ-ACK information, and after the compressed data is reconstructed by 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 correspondence may be stored in a form or a document description. For example, as shown in table 1, the first correspondence relation may be set for a case where the number of ACK bits is far greater than the number of NACK bits in table 1. It should be noted that table 1 is only an example, and in table 1, the division is performed by 4 bits, in table 1, the original a/N bits are bit combination information before compression processing, and compression encoding 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 correspondence, for example, after division, the bit data corresponding to a certain HARQ-ACK packet is "1111", and then it may be determined by the correspondence in table 1 that the corresponding bit data after compression encoding should be "10", that is, the second information corresponding to the "1111" packet is "10". Of course, the corresponding relationship may also be other expression forms, which are not illustrated herein, and the expression forms of the corresponding relationship are not limited in the embodiments of the present application.

In table 1, since the probability of occurrence of a bit combination including a large number of ACK bits is highest at the time of statistics, the number of bits included in the corresponding combination after compression encoding is the smallest. Therefore, table 1 is applicable to feedback information having many more ACK bits than NACK bits, so that the compression efficiency can be ensured after compression encoding.

In one possible implementation, table 1 may be suitable for enhanced mobile broadband (Enhanced Mobile Broadband, eMBB) traffic, or low latency high reliability communication (Ultra-relaible and Low Latency Communication, URLLC) traffic, in which the target Bler value is typically set to 10%, i.e. the ratio of ACKs to NACKs included in the feedback information is not less than 9:1, and in URLLC traffic the target Bler value is typically set to less than 1%, i.e. the ratio of ACKs to NACKs in the feedback information is not less than 99:1, i.e. the number of ACKs is far greater than the number of NACKs. Therefore, in these two scenarios, the corresponding relationship in table 1 is used to perform compression encoding on each HARQ-ACK packet, and the finally obtained first information will contain a smaller number of bits, so that the transmission effectiveness can be improved. Of course, the correspondence in table 1 may be used in other traffic having a number of ACK bits far greater than the number of NACK bits, and is not limited herein.

That is, by performing compression processing through the first correspondence shown in table 1, when compression is actually performed, the number of ACK bits is far greater than that of NACK, and by compressing the HARQ-ACK packet including the number of ACK bits more into the smaller number of bits, the compression efficiency is improved, and the transmission efficiency of feedback information is also improved.

Referring to table 2, table 2 shows the compression code rate after compression encoding of some original HARQ-ACK bit data when the target Bler is 10% and the ratio of ACK to NACK is 9:1, where the data in table 2 corresponds to the first correspondence shown in table 1, specifically, the second information of each HARQ-ACK packet is determined according to the first correspondence 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 the HARQ-ACK information is compressed according to the first correspondence in table 1, the number of bits of feedback information to be transmitted in the transmission process can be effectively reduced, thereby improving the transmission efficiency of the feedback information.

In a possible implementation manner, the first correspondence may be determined according to historical data, that is, the network device may set a specific target Bler, then determine, from the historical HARQ-ACK data satisfying the target Bler, a bit combination with the highest probability of being transmitted, and set the bit combination to correspond to the minimum number of bits after compression encoding, so as to obtain a compression encoding table (i.e., the first correspondence), and a specific determination process may be understood in the same manner with reference to the foregoing determination method, which is not described herein again.

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

Of course, the corresponding relationship may be other expression forms, which are not limited in the embodiment of the present application.

In a specific implementation process, after obtaining the second information corresponding to each HARQ-ACK packet, the second information may be summarized and sent to the network device as final first information, or the summarized second information may be processed to a certain degree and then sent to the network device.

In one possible implementation, for example, a target compression coding rate is pre-predetermined between the terminal device and the network device, where the target compression coding rate may be referred to as a first compression coding rate, i.e., when the terminal device sends feedback information to the network device, the number of bits included in the sent feedback information should be the number of bits compressed according to the first compression coding rate, and for convenience of distinction, the number of bits included in the HARQ-ACK information compressed by the first compression coding rate may be referred to as a third number of bits, for example. However, there may be a difference between the obtained number of bits and the third number of bits after the actual compression processing is performed, 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 first subjected to the padding processing and then transmitted after being padded to the third number of bits.

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

The first compression coding rate is generally higher than the lowest coding rate to ensure that the padding of redundant bits can be achieved, and therefore, the third number of bits obtained by performing compression processing through the first compression coding rate is generally greater than or equal to the second number of bits, and therefore, when performing padding processing on the second number of bits, it can be understood that a certain number of bits is increased so that the second number of bits is equal to the third number of bits.

In a specific embodiment, before the second number of bits is padded, a difference between the third number of bits and the second number of bits may be determined, and then the third number of bits is padded according to the difference. In a specific implementation, if the difference is 1, then the third number of bits may be followed by a bit "1", and if the difference is greater than 1, then the padding may be performed with a plurality of combined bits "10" until only one bit is different, then the bit "1" is again appended. It should be noted that only a specific example is given here, and the filling process may be performed by other means, which is not limited herein.

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

TABLE 4 Table 4

The process of padding the second number of bits is described below by way of a specific example. Assuming that the first HARQ-ACK information includes 32 bits of data, if the target compression rate 75% in table 3 is taken as an example, the first information to be 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 compressing, 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 23 bits are then filled with bits "1" before being transmitted to the network device; or the actual compression is carried out to comprise 22 bits of data, and the difference between the second bit quantity and the third bit quantity is 2, then the 22 bits are filled with bit combination '10', and then the data is transmitted as first information; or the actual compression is followed by 21 bits of data, where the difference between the second and third numbers of bits is 3, then the 21 bits need to be followed by the padding of bit combination "10", followed by the refilling of bit "1", and finally transmitted as the first information.

In one possible implementation manner, after obtaining the first information, the terminal device may send the compressed information when performing compression processing to the network device, 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 is the same as the network device in understanding the compressed HARQ-ACK information, 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, which 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 bits after the compression according to the first difference, and then decompresses the compressed HARQ-ACK information (i.e. the first information).

Or the fourth information sent by the terminal equipment can be the bit number included after the first HARQ-ACK information is compressed, and the method can be also understood as that the terminal equipment informs the network equipment of the compressed information in an explicit mode, so that the network equipment 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, which may also be understood as that the terminal device informs the network device of the compression information in an implicit manner, so that the network device determines the number of bits after compression 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 process, so that after receiving the first information, the network device performs the decompression process on the compressed HARQ-ACK information according to the fourth information included therein. Alternatively, the fourth information may be sent separately, that is, after the first information is obtained, the terminal device may send the fourth information to the network device separately, to inform the specific compression processing manner, and the manner of sending the fourth information is not limited in the embodiments of the present application.

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

In a specific embodiment, after obtaining the first information, the terminal device may send the first information to the network device, that is, send the compressed HARQ-ACK information to the network device, so as to reduce the amount of information transmission and improve the transmission efficiency of the HARQ-ACK information.

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

In a specific embodiment, after the network device receives the first information sent by the terminal device, the first information may be decompressed, and specifically, the decompression may be performed according to the foregoing fourth information. After the network device decompresses the first information, the network device can obtain complete HARQ-ACK feedback information, and then determine whether the terminal device successfully receives corresponding data according to the decompressed HARQ-ACK information, and when the terminal device does not successfully receive the corresponding data, the network device can retransmit the corresponding data to the terminal device.

The following describes the process of compression encoding the HARQ-ACK feedback information by the terminal device and the corresponding decompression encoding by the network device further by fig. 3. Referring to fig. 3, at the terminal device side, the terminal device compresses HARQ-ACK information, then performs a Code block level cyclic redundancy check (Code Block Cyclic Redundancy Check, CB-CRC) on the compressed HARQ-ACK codebook, then encodes through a corresponding Polar Code (Polar Code), then performs rate matching, then performs an interleaving process, and finally performs transmission.

Correspondingly, when the network equipment receives the compressed HARQ-ACK information, the network equipment firstly carries out de-interleaving treatment, then carries out de-rate matching treatment, then carries out Polar code decoding, and finally carries out de-CRC treatment, thus obtaining the original HARQ-ACK feedback information. The specific procedures are understood in the same manner by referring to the related art, and will not be described in detail herein.

In this embodiment of the present invention, 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, according to the first instruction, the terminal device may compress the HARQ-ACK information that needs to be compressed, so that when feedback information is actually sent, the sent first information may be the first information after being compressed, and when the sent feedback information is relatively more, the feedback information of different TBs or CBGs may not be packaged, and also the number of transmitted information bits may be effectively reduced, thereby improving the transmission efficiency of the HARQ-ACK information.
