[0038] For the purposes of the present application, the term "coupled" is used to describe both an indirect connection and a direct connection. The term "coupled" is used herein to express an indirect or direct connection between two elements in a manner that is not necessarily mutually exclusive. In the following description, numerous specific details are set forth to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the overall present application can be practiced without the specific details. In other instances, well-known methods have not been shown or described in detail in order not to obscure the present application. Like reference numerals in the drawings and the following description represent similar elements.

[0039] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0040] It is to be understood that the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. It is to be understood that the term "and / or" as used herein encompasses all possible combinations of particular items listed. It is to be understood that, although the terms first, second, third, etc. can be used herein to describe various information, the information is not to be limited by these terms. These terms are only used to distinguish one piece of information from another. For example, a first information can be termed a second information, and, similarly, a second information can be termed a first information without departing from the scope of the present application. The word "if" as used herein means "according to a determination" or "in response to a determination" or "in response to a positive determination" depending on the context. In the present description, when expressing the meaning of Boolean Value, it is expressed as "0" represents "first meaning", "1" represents "second meaning", without loss of generality, the skilled in the art can understand that the representative meaning can be reversed, i.e., "1" represents "first meaning", "0" represents "second meaning".

[0041] Hybrid Automatic Repeat reQuest (HARQ) is a technique that combines Automatic Repeat reQuest (ARQ) and Forward Error Correction (FEC) to improve the reliability of data transmission. In a wireless communication system, HARQ technology allows the receiving party to request the transmitting party to retransmit data when errors are detected upon receiving data packets, while the transmitting party also uses forward error correction coding to improve the anti-interference ability of data.

[0042] A new radio (NR) system supports scheduling and HARQ feedback based on a transport block (TB) level, that is, a cyclic redundancy check (CRC) information is added to each TB, and the CRC information is generated based on the entire TB, so it can be considered as a CRC for the TB or a TB-level CRC (TB-level CRC). The receiving end determines whether the TB is correctly decoded based on the checking result of the TB-level CRC, and feeds back an acknowledgement (ACK) if it is correct, or a negative acknowledgement (NACK) if it is not correct. The feedback information only needs to be represented by 1 bit. The sending end will decide whether to retransmit the TB according to the received ACK or NACK. A large TB will be divided into multiple code blocks (CBs), and any failed CB decoding will cause the entire TB to be retransmitted.

[0043] In order to improve the retransmission efficiency of large data packets, the NR also supports a more refined HARQ-ACK / NACK state feedback mechanism, that is, scheduling and feedback based on a code block group (CBG). The CBG-based feedback method is to approximately uniformly divide the CBs contained in a TB into N CBGs, wherein each CBG includes at least one CB, such as a plurality of consecutive CBs in a CBG, and each CBG corresponds to 1 bit of HARQ-ACK information. If any CB in the CBG fails to decode, the feedback information corresponding to the CBG is NACK. If all CBGs in the TB are successfully decoded, but the TB-level CRC check fails or does not pass, the feedback information corresponding to all CBGs of the TB is NACK. The purpose of introducing the CBG-based HARQ-ACK method is to improve the data retransmission efficiency, that is, if some CBGs in a large TB fail to decode, only the failed CBGs need to be scheduled for retransmission, instead of retransmitting the entire TB.

[0044] From the perspective of retransmission efficiency, the smaller the granularity of CBG is, the better, that is, the most ideal state is that each CB corresponds to a dedicated 1-bit feedback information. However, when the feedback granularity becomes smaller, the feedback overhead will increase accordingly. The reliability requirement of feedback information is much higher than that of data, so the capacity of uplink control signaling is usually not large. Considering the downlink retransmission efficiency and the uplink control signaling overhead, in the single code word transmission of the NR system, a TB can be divided into at most 8 CBGs; in the double code word transmission, a TB can be divided into at most 4 CBGs. That is, a downlink channel corresponds to at most 8-bit HARQ feedback information. The downlink channel includes a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), and the like.

[0045] Although the NR system supports retransmission for ACK / NACK information, the main purpose is to solve the ACK / NACK information not correctly received in the previous transmission, so the content of the retransmitted ACK / NACK information is exactly the same as that of the ACK / NACK information in the previous transmission.

[0046] The present application provides an information feedback method, which can adjust the retransmission content of feedback information, realize more refined information feedback, and improve the retransmission efficiency in the system.

[0050] In some embodiments, the network device 110 and the terminal device 120 both support the 3rd Generation Partnership Project (3GPP) protocol, but are not limited to the 3GPP protocol.

[0051] In some embodiments, the frequency bands that the wireless communication system 100 can support include but are not limited to a centimeter wave frequency band (such as a frequency band in the range of 450 MHz-6 GHz, also called a Sub-6 GHz frequency band), a millimeter wave (mmWave) frequency band (such as a frequency band in the range of 30-300 GHz, such as 45 GHz, 60 GHz, etc.), and a low frequency band.

[0054] FIG. 2 shows a flowchart of an information feedback method provided by an example embodiment of the present application, the method being performed by a first wireless device, and the method comprising at least part of the following steps:

[0055] Step 220: sending first information in the first resource, the first information comprising the reception failure information of the first data.

[0056] The receiving failure information of the first data is used to feed back the receiving failure or the non-receiving success of the first data. The receiving failure information can also be referred to as decoding failure information or demodulation failure information.

[0057] In some embodiments, the first resource comprises one or more of the following: a time domain resource, a frequency domain resource, and a spatial domain resource.

[0058] Step 240: sending second information in a second resource, the second information comprising feedback information of a plurality of data parts in the first data; wherein the second resource is after the first resource.

[0059] The first data comprises a plurality of data parts, and the feedback information of the plurality of data parts is used to feed back whether the plurality of data parts are received successfully or unsuccessfully. Therefore, the second information can comprise receiving failure information of at least one data part, or can comprise receiving success information of at least one data part. The receiving success information can also be referred to as decoding success information, or demodulation success information, or correct receiving information.

[0060] The second resource is after the first resource, which means that the second resource is after the first resource in the time domain, i.e., the time domain position of the second resource is not earlier than that of the first resource. Therefore, the first wireless device sends the first information before sending the second information.

[0061] In some embodiments, the second resource comprises one or more of the following: a time domain resource, a frequency domain resource, and a spatial domain resource.

[0062] In the embodiments of the present application, the first wireless device can be the network device 110 or the terminal device 120 shown in FIG. 1.

[0063] In summary, the method provided by the embodiments of the present application supports the first wireless device to send feedback information of a plurality of data parts in the first data after feeding back the receiving failure information of the first data, so as to provide more refined receiving success feedback or receiving failure feedback. The method can enable the receiver of the first information and the second information to more accurately know the receiving situation of the first data, which helps to more accurately retransmit the data parts, thereby improving the accuracy and efficiency of retransmission.

[0064] In some embodiments, on the basis of the embodiment shown in FIG. 2, step 220 can be further implemented as step 320, and step 240 can be further implemented as step 340, as shown in FIG. 3. Optionally, the information feedback method further comprises step 360.

[0065] FIG. 3 shows a flowchart of an information feedback method provided by an example embodiment of the present application, which is performed by a first wireless device, and the method comprises at least part of the following steps:

[0066] Step 320: transmitting first information in the first resource, the first information comprising the reception failure information of the first data.

[0067] In some embodiments, the first data comprises: a group of TBs, or a TB, or a group of HARQ processes, or a HARQ process, or a group of data carried by physical channels, or data carried by a physical channel, or a group of data units. Exemplarily, the physical channels comprise a Physical Downlink Shared Channel (PDSCH) and / or a Physical Uplink Shared Channel (PUSCH).

[0068] In some embodiments, the data unit comprises: a CB, or a group of CBs (i.e., a CBG), or data supporting independent encoding, or data supporting independent decoding, or data supporting independent generation of feedback information. That is, if the first data comprises a group of data units, a single data unit can be a CB or a CBG, or a single data unit corresponds to a single encoding result, or a single data unit corresponds to a single decoding result, or a single data unit corresponds to a single feedback information.

[0069] In some embodiments, the first data is downlink data or uplink data.

[0070] In some embodiments, the reception failure information of the first data comprises negative acknowledgement information corresponding to the first data, such as NACK.

[0071] Other contents refer to step 220, which will not be repeated here.

[0072] Step 340: transmitting second information in the second resource, the second information comprising feedback information of a plurality of data portions in the first data; wherein the second resource is after the first resource.

[0073] In some embodiments, the data portion comprises: a CB, or a group of CBs (i.e., a CBG), or data supporting independent encoding, or data supporting independent decoding, or data supporting independent generation of feedback information. That is, the first data comprises a plurality of data portions, wherein a single data portion can be a CB or a CBG, or a single data portion corresponds to a single encoding result, or a single data portion corresponds to a single decoding result, or a single data portion corresponds to a single feedback information.

[0074] In some embodiments, in the case that the first data comprises a group of data units and the first data comprises a plurality of data portions, a data portion comprises less data than the group of data units.

[0075] In some embodiments, the feedback information of a data portion comprises one or more of the following: positive acknowledgement information corresponding to the data portion, e.g., ACK; negative acknowledgement information corresponding to the data portion, e.g., NACK; information obtained by the first wireless device in decoding the data portion; and information obtained by the first wireless device in receiving the data portion. The information obtained by the first wireless device in decoding or receiving the data portion can include, for example, the number of decoding iterations, which can reflect the coding reliability and affect the decoding performance and complexity. Generally, increasing the number of decoding iterations can improve the decoding performance and coding reliability, but also increase the decoding complexity.

[0076] For example, the feedback information of a data portion comprises: positive acknowledgement information corresponding to the data portion; or negative acknowledgement information corresponding to the data portion; or information obtained by the first wireless device in decoding the data portion; or information obtained by the first wireless device in receiving the data portion.

[0077] For example, the feedback information of a data portion comprises: positive acknowledgement information corresponding to the data portion; and information obtained by the first wireless device in decoding the data portion.

[0078] For example, the feedback information of a data portion comprises: positive acknowledgement information corresponding to the data portion; and information obtained by the first wireless device in receiving the data portion.

[0079] For example, the feedback information of a data portion comprises: negative acknowledgement information corresponding to the data portion; and information obtained by the first wireless device in decoding the data portion.

[0080] For example, the feedback information of a data portion comprises: negative acknowledgement information corresponding to the data portion; and information obtained by the first wireless device in receiving the data portion.

[0081] In some embodiments, the feedback information of a plurality of data portions comprises one or more of the following: positive acknowledgement information corresponding to at least one data portion; negative acknowledgement information corresponding to at least one data portion; information obtained by the first wireless device in decoding at least one data portion; and information obtained by the first wireless device in receiving at least one data portion. The at least one data portion can be one or more data portions.

[0082] In some embodiments, the first information comprises TB-level negative acknowledgement information (e.g., TB-level NACK) of the first data, and the second information comprises CBG-level acknowledgement information (e.g., CBG-level ACK / NACK) or CB-level acknowledgement information (e.g., CB-level ACK / NACK) of the first data. Thus, the feedback granularity of the second information is smaller than that of the first information, and the second information is more refined than the first information.

[0083] In some embodiments, the first information comprises CBG-level negative acknowledgement information (e.g., CBG-level NACK) of the first data, and the second information comprises CB-level ACK / NACK of the first data. Thus, the feedback granularity of the second information is smaller than that of the first information, and the second information is more refined than the first information.

[0084] In some embodiments, the first information comprises CBG-level NACK of the first data, and the second information comprises CBG-level ACK / NACK of the first data, but the CB grouping granularity used by the second information is smaller than that used by the first information, i.e., the second information corresponds to a single CBG that includes a smaller number of CBs than the single CBG corresponding to the first information. Thus, the first information and the second information both can feedback the CBG-level reception status of the first data, but the feedback granularity of the second information is smaller than that of the first information, thereby achieving more refined information feedback.

[0085] In some embodiments, the first information comprises reception failure information of X first data, and the second information comprises X sets of feedback information, and the X sets of feedback information are arranged in the order of the first data in the first information.

[0086] Exemplarily, taking the first information comprising TB-level NACK of the first data as an example, the first information is {NACK TB1 , ACK TB2 , ACK TB3 , NACK TB4}, indicating that the reception status of TB1 and TB4 is NACK, and the reception status of TB2 and TB3 is ACK, then the corresponding CB or CBG-level ACK / NACK information is concatenated together in the second information in the order of TB1 and then TB4.

[0087] In some embodiments, the second information corresponds to a plurality of first information; wherein the transmission resources of the plurality of first information are different, and / or the plurality of first information carries reception failure information corresponding to different data.

[0088] In some embodiments, the second information is obtained based on a resource order of the plurality of first information, and the resource order of the plurality of first information includes any one of the following: the plurality of first resources carrying the plurality of first information are arranged in a time domain order; the plurality of first resources carrying the plurality of first information are arranged in a time domain first and then frequency domain order; the plurality of first resources carrying the plurality of first information are arranged in a time domain first and then frequency domain and then resource number order.

[0089] For example, the plurality of first resources carrying the plurality of first information are arranged in one or more of the following orders: ascending time domain order, descending time domain order, ascending frequency domain order, descending frequency domain order, ascending resource number order, descending resource number order. That is, the order of the plurality of first resources carrying the plurality of first information includes ascending or descending order of one or more dimensions such as time domain, frequency domain, and resource number, and the order of different dimensions can be adjusted according to actual conditions. For example, in the case of two dimensions, it can be time domain first (ascending or descending) and then frequency domain (ascending or descending), time domain first (ascending or descending) and then resource number (ascending or descending), frequency domain first (ascending or descending) and then resource number (ascending or descending), frequency domain first (ascending or descending) and then time domain (ascending or descending), resource number first (ascending or descending) and then time domain (ascending or descending), resource number first (ascending or descending) and then frequency domain (ascending or descending), and the like. The case of three dimensions is similar, and all possible cases are not listed here.

[0090] For example, the time domain order includes the order of the start position of the time domain or the order of the end position of the time domain. The frequency domain order includes the order of the cell or the order of the carrier. The resource number order includes the order of the channel number in the cell, such as PUCCH Index, or the order of the frequency domain resource number in the cell, such as Resource Block (RB) Index.

[0091] In some embodiments, the second information is transmitted by the first wireless device based on the first signaling, or is autonomously transmitted by the first wireless device. For example, step 340 can be further implemented as step 340a or step 340b.

[0092] Step 340a: According to the indication or trigger of the first signaling, the first wireless device transmits the second information in the second resource, and the second information includes feedback information of the plurality of data parts in the first data; wherein the second resource is after the first resource.

[0093] In some embodiments, the first signaling comprises Downlink Control Information (DCI), or Uplink Control Information (UCI), or Media Access Control (MAC) Control Element (CE) signaling, or Radio Resource Control (RRC) signaling.

[0094] In some embodiments, the first signaling is transmitted by the second wireless device to the first wireless device after receiving the first information.

[0095] In some embodiments, the first signaling comprises a first information field, the first information field being used to indicate retransmission of the first information or transmission of the second information.

[0096] Exemplarily, in a case where the first information field is of a first value, the second information comprises ACK / NACK information of one or more data parts in the first data. This design is especially suitable for a case where the second wireless device has correctly received the first information within the first resource, and the second wireless device wants or needs to know the ACK / NACK information for the data parts more accurately.

[0097] Exemplarily, in a case where the first information field is of a second value, the second information comprises the first information, that is, the second information is a retransmission of the complete first information. This design is especially suitable for a case where the second wireless device has not correctly received the first information within the first resource, and the second wireless device wants or needs the first wireless device to retransmit the complete first information.

[0098] In some embodiments, the first signaling comprises a second information field, the second information field being used to indicate one or more of the following information: a bit number of the second information; the second information is generated based on CB; the second information is generated based on CBG; a CBG number corresponding to the second information; an upper limit of the CBG number corresponding to the second information; a CB number within one CBG corresponding to the second information; an upper limit of the CB number within one CBG included in the first data; the second information is obtained based on a first set of mapping relationships, the first set of mapping relationships being one set of the at least one set of mapping relationships.

[0099] In some embodiments, the at least one set of mapping relationships is preconfigured, or agreed by a communication protocol, or configured by a network device, or reported by a terminal device.

[0100] In some embodiments, the first set of mapping relationships can be represented as a table, or a codebook, or a set of information sequences.

[0101] In some embodiments, the first set of mapping relationships is about mapping relationship of A-bit response information and reception information of B data portions included in the first data; where A is an integer greater than or equal to 1, and B is an integer greater than or equal to 1. Optionally, B is less than or equal to 2 raised to the power of A (i.e., B≤2 A ) or log2(B) is less than or equal to A, or less than or equal to A, denotes rounding up; or less than or equal to A, denotes rounding down.

[0102] In some embodiments, the first wireless device generates the second information based on the indication of the second information field. For example, the first wireless device generates the second information based on the number of bits indicated by the second information field. For example, the second information field indicates that the second information is generated based on CB, and the first wireless device generates CB-level ACK / NACK information. For example, the second information field indicates that the second information is generated based on CBG, and the first wireless device generates CBG-level ACK / NACK information. For example, the second information field indicates an upper limit of the number of CBGs corresponding to the second information, and the first wireless device divides the first data into CBGs whose number is less than or equal to the upper limit of the number of CBGs indicated by the second information field, and the division of CBGs can be equal grouping or approximate equal grouping or non-equal grouping. For example, the second information field indicates an upper limit of the number of CBs within a CBG corresponding to the second information, and the first wireless device divides the first data into a single CBG whose number of CBs is less than or equal to the upper limit of the number of CBs indicated by the second information field, and the division of CBs can be equal grouping or approximate equal grouping or non-equal grouping. For example, the second information field indicates that the second information is obtained based on the first set of mapping relationships, and the first wireless device generates the second information according to the first set of mapping relationships. The case where the second information field indicates other information is described above and cannot be listed here.

[0103] In some embodiments, the first signaling includes a third information field, and the third information field is used to indicate the first information or the first data corresponding to the second information. The third information field helps the first wireless device to explicitly perform more refined feedback for which first information or which data.

[0104] Therefore, after sending the first information, the first device informs the second wireless device of feedback information of the plurality of data parts in the first data based on an indication or trigger of the first signaling sent by the second wireless device. In one aspect, this design can ensure that the sending of the second information meets the needs or expectations of the second wireless device, guarantee the communication efficiency in the system, and avoid waste of transmission resources. On the other hand, the first signaling can further carry indication information, so that the content of the second information is more detailed and accurate, and more meets the needs or expectations of the second wireless device, thereby improving the feedback efficiency.

[0105] Step 340b: In the case where the first information includes the reception failure information of the first data, the first wireless device sends the second information.

[0106] In some embodiments, the time domain interval between the first information field and the second information is pre-configured, or agreed by the communication protocol, or configured by the network device, or reported by the terminal device.

[0107] Therefore, after sending the first information including the reception failure information of the first data, the first wireless device can autonomously send the second information to inform the second wireless device of the feedback information of the plurality of data parts in the first data. Such a design can save the signaling interaction between the first wireless device and the second wireless device, simplify the information feedback process, save transmission resources, and improve the feedback efficiency.

[0108] Step 360: Receiving retransmission of one or more data parts in the first data.

[0109] The second wireless device sends retransmission data of the first data to the first wireless device according to the reception failure information carried by the first information and the feedback information carried by the second information, where the retransmission data can include complete first data, i.e., all data in the first data, or only part of the data in the first data.

[0110] In summary, the method provided by the embodiments of the present application supports the first wireless device to send feedback information for multiple data parts in the first data after feeding back the reception failure information for the first data, so as to provide more refined reception success feedback or reception failure feedback. Generally, in the actual data receiving process, the reception status of a large amount of data should be ACK, and only a small amount of data has the reception status of NACK. If only the feedback accuracy is considered, and all the feedback information is configured as CB or CBG level, it will inevitably cause low uplink feedback efficiency and affect the transmission reliability of the uplink control signaling. Therefore, the method feeds back the relatively rough ACK / NACK information first, and then makes refined feedback for the data that has been fed back as NACK. This can not only avoid damaging the uplink feedback efficiency, improve the uplink resource utilization efficiency, and guarantee the transmission reliability of the uplink control signaling, but also enable the second wireless device to more accurately know the reception status of the first data, which helps the second wireless device to retransmit the data parts of the first data, avoid unnecessary data retransmission, and thus improve the accuracy and efficiency of the retransmission.

[0111] FIG. 4 shows a flowchart of a method of information feedback provided by an example embodiment of the present application, which is performed by a second wireless device, and includes at least part of the following steps:

[0112] Step 420: receiving first information in the first resource, the first information including reception failure information of the first data.

[0113] The reception failure information of the first data is used to feed back the reception failure or the non-reception success of the first data. The reception failure information can also be referred to as decoding failure information or demodulation failure information.

[0114] In some embodiments, the first resource includes one or more of the following: time domain resource, frequency domain resource, and space domain resource.

[0115] Step 440: receiving second information in the second resource, the second information including feedback information for multiple data parts in the first data; wherein the second resource is after the first resource.

[0116] The first data includes multiple data parts, and the feedback information for the multiple data parts is used to feed back whether the multiple data parts are received successfully or failed. Therefore, the second information can include reception failure information for at least one data part, or can include reception success information for at least one data part. The reception success information can also be referred to as decoding success information, demodulation success information, or correct reception information.

[0117] The second resource is after the first resource, which means that the second resource is located after the first resource in the time domain, i.e., the time domain position of the second resource is not earlier than the time domain position of the first resource. Therefore, the second wireless device receives the first information first and then receives the second information.

[0118] In some embodiments, the second resource includes one or more of the following: a time domain resource, a frequency domain resource, and a space domain resource.

[0119] In the embodiments of the present application, the second wireless device can be the network device 110 or the terminal device 120 shown in FIG. 1.

[0120] In summary, the method provided by the embodiments of the present application supports the second wireless device receiving feedback information for multiple data parts in the first data after receiving the reception failure information for the first data, so as to realize more refined reception success feedback or reception failure feedback. The method can enable the second wireless device to more accurately know the reception situation of the first data, which helps the second wireless device to more accurately retransmit the data parts, thereby improving the accuracy and efficiency of retransmission.

[0121] In some embodiments, on the basis of the embodiments shown in FIG. 4, step 420 can be further implemented as step 520, and step 440 can be further implemented as step 540, as shown in FIG. 5. Optionally, the information feedback method further includes step 560.

[0122] FIG. 5 shows a flowchart of an information feedback method provided by an example embodiment of the present application, which is performed by a second wireless device, and includes at least part of the following steps:

[0123] Step 520: receiving first information in the first resource, wherein the first information includes reception failure information of the first data.

[0124] For related content, refer to step 420 and step 320, which are not described here again.

[0125] Step 540: receiving second information in the second resource, wherein the second information includes feedback information for multiple data parts in the first data; and the second resource is after the first resource.

[0126] For related content, refer to step 440 and step 340, which are not described here again.

[0127] In some embodiments, the second information is sent by the first wireless device based on the first signaling, or is sent by the first wireless device autonomously. Therefore, before step 540 is performed, the second wireless device can or can not send the first signaling.

[0128] In some embodiments, the second wireless device determines whether to send the first signaling. Exemplarily, the second wireless device determines whether to send the first signaling according to one or more of the following: whether the second information is pre-configured to be autonomously sent by the first wireless device, whether the first information comprises the reception failure information of the first data, whether a requirement of the second wireless device, whether an expectation of the second wireless device, whether an uplink resource, and whether a downlink resource.

[0129] In some embodiments, the second wireless device determines whether to receive the second information. Exemplarily, the second wireless device determines whether to receive the second information according to one or more of the following: whether the first information comprises the reception failure information of the first data, whether a requirement of the second wireless device, whether an expectation of the second wireless device, whether an uplink resource, and whether a downlink resource. It can be understood that the present application does not exclude the case that the second wireless device does not expect or require to receive the second information, nor does it exclude the case that the first wireless device cannot send the second information due to the limitation of resource configuration.

[0130] Step 560: retransmitting one or more data parts in the first data.

[0131] The second wireless device sends the retransmission data of the first data to the first wireless device according to the reception failure information carried by the first information and the feedback information carried by the second information, wherein the retransmission data can comprise the complete first data, i.e., all the data in the first data, or can comprise only part of the data in the first data.

[0132] In summary, the method provided by the embodiments of the present application supports the second wireless device to receive the feedback information for the multiple data parts in the first data after receiving the reception failure information for the first data, so as to achieve more refined reception success feedback or reception failure feedback. Generally speaking, in the actual data receiving process, the reception status of a large amount of data should be ACK, and only a small amount of data has the reception status of NACK. If only the feedback accuracy is considered, and all the feedback information is configured as CB or CBG level, it will inevitably cause low uplink feedback efficiency and affect the transmission reliability of the uplink control signaling. Therefore, the method can avoid damaging the uplink feedback efficiency, improve the uplink resource utilization efficiency, guarantee the transmission reliability of the uplink control signaling, and also enable the second wireless device to more accurately know the reception status of the first data, which is helpful for the second wireless device to retransmit the data parts of the first data, avoid unnecessary data retransmission, and thus improve the accuracy and efficiency of the retransmission.

[0133] FIG. 6 shows a flowchart of an information feedback method provided by an exemplary embodiment of the present application, which is executed by a first wireless device and a second wireless device, and comprises at least part of the following steps:

[0134] Step 610: The second wireless device sends one or more first data to the first wireless device.

[0135] The transmission resource of the plurality of first data is the same or different.

[0136] Step 620: The first wireless device sends first information to the second wireless device in the first resource.

[0137] In some embodiments, one first information includes the reception failure information of one or more first data.

[0138] In some embodiments, one first information includes the reception failure information of one first data. If there are multiple first data reception failures, the first wireless device sends multiple first information to the second wireless device in the first resource.

[0139] For other contents, refer to step 420, step 320, which will not be repeated here.

[0140] Step 630: The second wireless device sends first signaling to the first wireless device.

[0141] For related contents, refer to step 340a, which will not be repeated here.

[0142] Step 640: The first wireless device sends second information to the second wireless device in the second resource.

[0143] The second information includes the feedback information of the plurality of data parts in the first data. The second resource is after the first resource.

[0144] In some embodiments, one second information corresponds to multiple first information; wherein the transmission resource of the plurality of first information is different, and / or the plurality of first information carries the reception failure information corresponding to different data.

[0145] In some embodiments, one second information corresponds to one first information. If in step 620, the first wireless device sends multiple first information to the second wireless device in the first resource, the first wireless device sends multiple second information in the second resource. If in step 620, the first wireless device sends one first information to the second wireless device in the first resource, the first wireless device sends one second information in the second resource.

[0146] For other contents, refer to step 440, step 340, which will not be repeated here.

[0147] Step 650: The second wireless device sends retransmission data to the first wireless device.

[0148] The second wireless device retransmits the one or more first data to the first wireless device, or the second wireless device retransmits part of the one or more first data to the first wireless device.

[0149] To sum up, the method provided by the embodiments of the present application supports the first wireless device to send feedback information for multiple data parts in the first data after feeding back the reception failure information for the first data, so as to realize more refined reception success feedback or reception failure feedback. The method can avoid damaging the uplink feedback efficiency, improve the uplink resource utilization efficiency, guarantee the transmission reliability of the uplink control signaling, and make the second wireless device more accurately know the reception status of the first data, which helps the second wireless device to retransmit the data parts of the first data, avoid unnecessary data retransmission, and thus improve the accuracy and efficiency of retransmission. The sending of the first signaling also helps to ensure that the second information meets the needs or expectations of the second wireless device and improves the feedback efficiency.

[0150] FIG. 7 shows a schematic diagram of the information feedback method provided by an example embodiment of the present application. Taking an example of the second wireless device sending multiple first data (TB1 and TB2) to the first wireless device, the first resource includes PUCCH 1, and the second resource includes PUCCH 2.

[0151] The first wireless device receives TB1 and TB2 in the PDSCH and sends TB-level ACK / NACK information (such as TB-level ACK / NACK) corresponding to TB1 and TB2 in the PUCCH 1, that is, 1-bit ACK / NACK information for each TB.

[0152] Suppose that the reception status of TB2 is ACK, the reception status of TB1 is NACK, and TB1 contains multiple CBs or CBGs. In order to improve the transmission efficiency and avoid retransmitting the correctly decoded CBs or CBGs, the second wireless device can further trigger or instruct the first wireless device to send CB-level ACK / NACK information (such as CB-level ACK / NACK or CBG-level ACK / NACK) for TB1 through the first signaling.

[0153] The first wireless device sends CB-level ACK / NACK information corresponding to TB1 in the PUCCH 2 based on the indication or trigger of the first signaling, and FIG. 7 takes an example of the first wireless device sending CB-level ACK / NACK in the PUCCH 2.

[0154] But it does not exclude the case that the first signaling is autonomously sent by the first wireless device. For example, in the case that the reception status of TB1 is NACK, the first wireless device autonomously sends the CB or CBG level ACK / NACK information corresponding to TB1 in PUCCH 2, without the need of the second wireless device to further trigger or instruct by the first signaling.
