Technical Field

Background

CSI (Channel State Information ) refers to information used to estimate the channel characteristics of a communication link. The network device can determine the modulation scheme, the channel coding rate and the like of the downlink data based on the CSI reported by the terminal device, so as to improve the transmission reliability and the transmission efficiency of the downlink data.

In Rel-15 (Release 15, 15 th edition) and Rel-16 (Release 16, 16 th edition) of an NR (New Radio, new air interface) system, CSI is obtained and reported to a network device based on measurement of CSI-RS (CSI Reference Signals, CSI reference signal) resources by the terminal device. In Rel-15 and Rel-16, reporting of CSI is divided into: periodically reporting the CSI, semi-continuously reporting the CSI and aperiodically reporting the CSI. In some implementations, in order to satisfy both the low latency and high reliability characteristics of the URLLC (Ultra-Reliable and Low Latency Communication, low latency and high reliability communication) service, the terminal device is required to report more accurate channel state information reflecting the channel quality, so as to assist the network device in better performing initial transmission and/or retransmission scheduling.

In order to meet the requirements of low latency and high reliability of the URLLC service and simultaneously improve the transmission efficiency of the system, new channel state information, otherwise referred to as "case-2new reporting", is proposed in NR Rel-17 (Release 17, 17 th edition). Further discussion and study is needed for how the terminal device determines the channel quality of PDSCH (Physical Downlink Shared Channel ) in a manner that indicates the channel quality to the network device through the new channel state information.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

First, some nouns and related technologies and the like referred to in the embodiments of the present application are briefly described.

1. TB-based PDSCH transmission and CBG-based PDSCH transmission

For PDSCH transmission based on TB (Transport Block), the terminal device receives the PDSCH transmitted by the network device, and feeds back HARQ (Hybrid Automatic Repeat reQuest ) -ACK (Acknowledgement) for this PDSCH. Wherein, in case of correctly demodulating one TB, the terminal device generates an ACK bit; in case the TB is not demodulated correctly, the terminal device generates NACK (Negative Acknowledgement ) bits.

In some implementations, the NR system also supports CBG-based PDSCH transmission. For PDSCH transmission based on CBG (Code Block Group), the terminal device determines the number of CBGs contained in one TB as follows: m=min (N, C), where N is the number of maximum CBGs per TB configured by the network device, and C is the number of CBs (Code blocks) contained by the TB. In some implementations, the principle of dividing one TB into M CBGs is to allocate as evenly as possible.

For CBG-based PDSCH transmissions, in the case of correctly receiving all CBs within a CBG, the terminal device generates ACK bits for that CBG; in case there is at least one CB in the CBG with a demodulation error, the terminal device generates NACK bits for the CBG.

2. Channel State Information (CSI)

CSI refers to information used to estimate the channel characteristics of a communication link. The network device can determine the modulation scheme, the channel coding rate and the like of the downlink data based on the CSI reported by the terminal device, so as to improve the transmission reliability and the transmission efficiency of the downlink data.

In Rel-15 and Rel-16 of the NR system, the CSI is acquired and reported to the network device based on measurement of the CSI-RS resource by the terminal device. In Rel-15 and Rel-16, reporting of CSI is divided into: periodically reporting the CSI, semi-continuously reporting the CSI and aperiodically reporting the CSI.

And periodically reporting CSI: the network device configures a period and an offset for reporting CSI for the terminal device through RRC (Radio Resource Control ) signaling, and after the terminal device receives the RRC signaling, the terminal device periodically reports CSI on a PUCCH (Physical Uplink Control Channel ) configured by the network device.

Semi-persistent reporting CSI: under the condition that the terminal equipment reports the CSI semi-continuously through the PUCCH, the network equipment activates/deactivates the reporting of the CSI through a Media Access Control (MAC) CE signaling, and after the reporting of the CSI is activated by the MAC CE signaling, the terminal equipment periodically reports the CSI on the PUCCH; under the condition that the terminal equipment reports the CSI semi-continuously through a PUSCH (Physical Uplink Shared Channel ), the network equipment activates/deactivates the reporting of the CSI through DCI (Downlink Control Information ), and after the reporting of the CSI is activated by the DCI, the terminal equipment periodically reports the CSI on the PUSCH.

Aperiodic reporting of CSI: the network equipment triggers the reporting of the CSI through the DCI, and the terminal equipment only reports the CSI once on the PUSCH indicated by the DCI after receiving the DCI.

In some implementations, the channel/interference measurement resources used to report CSI at slot n (slot n) cannot be later than the CSI reference resource slot n-n _CSI-ref . For periodic and semi-persistent reporting of CSI, when only one CSI-RS is configured for channel measurement resources, n _CSI-ref Needs to be greater thanFor aperiodic reporting of CSI, n _CSI-ref It needs to be greater than the CSI computation time, which is much greater than the PDSCH decoding time.

In order to satisfy the two characteristics of low latency and high reliability of the URLLC service (for example, ensure that the transmission times of the URLLC service within the allowable range of latency can reach the reliability requirement), the terminal device is required to report more accurate channel state information reflecting the channel quality, so as to assist the network device in performing primary transmission and/or retransmission scheduling better. In one example, reporting more accurate channel state information may be achieved in the following manner.

(1) The periodic configuration of reporting CSI periodically/semi-continuously is very short;

(2) Aperiodic reporting of CSI is triggered using DCI.

Aiming at the mode (1), the network equipment is required to transmit the CSI-RS resources in a high density manner so as to obtain the rapidly updated channel state information, so that the expenditure of reference signals (CSI-RS resources) of the system is increased, and the expenditure of measurement and calculation of the terminal equipment is increased. Meanwhile, due to the influence of the CSI measurement time, the CSI reported by the terminal equipment needs to be obtained based on the CSI-RS measurement before the CSI reference resource, for the periodical/semi-persistent CSI reported in the Uplink time slot n, the CSI reference resource is the CSI-RS transmitted in the time slot n-4 at the earliest (supposing that the UL (Uplink) and the DL (Downlink) have the same subcarrier interval and only one CSI-RS resource is configured for channel measurement), and the interference condition of the terminal equipment is greatly influenced by the scheduling of the adjacent cells, and due to the long measurement time, the interference possibly suffered by the terminal equipment when the terminal equipment reports the CSI is changed, so that the CSI is inaccurate.

Aiming at the mode (2), the network equipment needs to send DCI to trigger the sending of the CSI-RS and the reporting of the CSI, on one hand, the DCI used for triggering the reporting of the CSI can only be the DCI (UL DCI) for scheduling the PUSCH, and the terminal equipment can have asymmetric uplink and downlink service and has no uplink service requirement, and under the condition, the UL DCI is wasted for triggering the reporting of the CSI; on the other hand, for aperiodic CSI reporting, the processing time from receiving UL DCI to transmitting CSI is long, and for delay-critical traffic, if the initial transmission is wrong and the delay requirement cannot tolerate CSI reporting, the network device can only use a very conservative MCS (Modulation and Coding Scheme, modulation and coding strategy) to schedule, resulting in a decrease in the transmission efficiency of the system.

In order to meet the requirements of low latency and high reliability of the URLLC service and simultaneously improve the transmission efficiency of the system, channel state information based on demodulation and/or measurement of PDSCH is proposed in Rel-17. The channel state information is acquired based on the demodulation and/or measurement of the PDSCH, so that the CSI-RS resource can be saved, the calculation power consumption and the processing time delay of the terminal equipment can be reduced, and the requirement of URLLC service can be well met.

However, how the terminal device determines the channel quality of PDSCH and indicates to the network device in a manner based on demodulation and/or measurement of PDSCH to obtain channel state information has not been mentioned and discussed in Rel-17. Based on this, the embodiment of the application provides a method for determining and transmitting indication information, which can be used for solving the technical problems. In the following, the technical solutions of the present application will be described in connection with several embodiments.

It should be noted that, in the embodiment of the present application, the "reporting CSI to the network device by the terminal device" may also be referred to as "reporting CSI to the network device by the terminal device" or may also be referred to as "feeding back CSI to the network device by the terminal device". It should be understood that these expressions have the same meaning and are interchangeable with one another.

Referring to fig. 1, a schematic diagram of a communication system according to an embodiment of the present application is shown. The communication system may include: a terminal device 10 and a network device 20.

The number of terminal devices 10 is typically plural, and one or more terminal devices 10 may be distributed within a cell managed by each network device 20.

The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of network device-capable devices may vary in systems employing different radio access technologies, for example in 5G (5 th-Generation, fifth Generation mobile communication technology) NR systems, called gndeb or gNB. As communication technology evolves, the name "network device" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal device 10 with the wireless communication function are collectively referred to as a network device.

Optionally, the network device 20 and the terminal device 10 communicate with each other via some air interface technology, such as Uu interface.

The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand the meaning thereof.

It should be understood that the technical solution of the embodiments of the present application may be applied to various communication systems, for example: a long term evolution (Long Term Evolution, LTE) system, a LTE frequency division duplex (Frequency Division Duplex, FDD) system, a LTE time division duplex (Time Division Duplex, TDD) system, a long term evolution advanced (Advanced Long Term Evolution, LTE-a) system, a NR system, an evolution system of a NR system, a LTE-based access to Unlicensed spectrum, LTE-U, an NR-U, wireless local area network (Wireless Local Area Networks, WLAN), wireless fidelity (Wireless Fidelity, wiFi), a next generation communication system, or other communication system over an Unlicensed frequency band, and the like.

Referring to fig. 2, a flowchart of a method for determining indication information according to an embodiment of the present application is shown, and the method may be applied to the communication system shown in fig. 1. The method may comprise at least part of the following steps.

In step 210, the terminal device determines, based on the PDSCH, indication information corresponding to the first data, where the indication information corresponding to the first data is used to indicate a decoding margin situation of the terminal device for the first data.

In the embodiment of the present application, the network device performs downlink data transmission through the PDSCH, where the downlink data transmission includes PDSCH transmission based on the first data, that is, the first data is carried in the PDSCH. In one example, the first data is a Transport Block (TB), and the PDSCH transmission based on the first data is a PDSCH transmission based on the transport block; alternatively, the first data is a Coded Block Group (CBG), and the PDSCH transmission based on the first data is a PDSCH transmission based on the coded block group. In some implementations, to reduce complexity of data encoding and/or data decoding, an input bit length of the encoder and/or decoder is limited, based on which the terminal device performs code block segmentation on the first data to obtain at least one second data when the number of bits included in the first data exceeds a threshold value. Optionally, in the case that the first data is a transport block, the second data is a Coding Block (CB) or a group of coding blocks; in the case where the first data is a coded block group, the second data is a coded block. In the following, several possible examples of the first data and the second data are exemplarily presented.

Illustratively, the first data includes at least one second data; the second data is a coding block; the first data is a transport block comprising at least one encoded block; alternatively, the first data is a set of code blocks including at least one code block.

Illustratively, the first data includes at least one second data; the second data is a coding block group; the first data is a transport block comprising at least one set of encoded blocks.

Illustratively, the first data includes at least one second data; the second data is a coding block; the first data is a transport block comprising at least one set of encoded blocks; wherein the at least one coding block is distributed in at least one coding block group.

In the embodiment of the application, PDSCH transmission based on the first data may reflect the channel quality of the PDSCH through the decoding margin condition for the first data. Based on this, in order to determine the channel quality of the PDSCH, the terminal device may determine, when receiving the downlink data transmission from the network device, or after receiving the downlink data transmission from the network device, indication information corresponding to first data, where the indication information corresponding to the first data is used to indicate a decoding margin situation of the terminal device for the first data. The number of bits occupied by the indication information is not limited, alternatively, the indication information occupies S bits, and S is a positive integer, for example, S is 1, or S is 2, or S is 3, or S is 4.

The decoding margin case may be divided into a high decoding margin (high decoding margin) and a low decoding margin (low decoding margin). In general, a high decoding margin reflects a better channel quality and a low decoding margin reflects a worse channel quality. Of course, the embodiments of the present application do not exclude the possibility that the high decoding margin reflects the channel quality relatively poor and the low decoding margin reflects the channel quality relatively good. Furthermore, the decoding result can be divided into correct decoding (the terminal device generates ACK bits) and incorrect decoding (the terminal device generates NACK bits) in general.

Based on this, in one example, the decoding margin case for the first data includes any one of: the method includes the steps of decoding correctly and high decoding margin, decoding correctly and low decoding margin, decoding incorrectly and high decoding margin, and decoding incorrectly and low decoding margin, so that the indication information corresponding to the first data includes any one of the following: ACK-high decoding margin, ACK-low decoding margin, NACK-high decoding margin, NACK-low decoding margin; in another example, the decoding margin case for the first data includes any one of: the decoding is correct and the decoding margin is high, the decoding is correct and the decoding margin is low, the decoding is incorrect, and therefore, the indication information corresponding to the first data comprises any one of the following: ACK-high decoding margin, ACK-low decoding margin, NACK; in yet another example, the decoding margin case for the first data includes any one of: the decoding is correct, the decoding is incorrect and the decoding margin is high, the decoding is incorrect and the decoding margin is low, so that the indication information corresponding to the first data comprises any one of the following: ACK, NACK-high decoding margin, NACK-low decoding margin.

Of course, the decoding margin case for the first data may include only any one of the following: the high decoding margin and the low decoding margin, so that the indication information corresponding to the first data includes any one of the following: high decoding margin, low decoding margin. Other implementations are also conceivable by those skilled in the art after understanding the technical solutions provided by the embodiments of the present application, for example, the decoding margin case for the first data includes any one of the following: the decoding is correct and the decoding margin is high, the decoding is failed and the decoding margin is high, and therefore, the indication information corresponding to the first data comprises any one of the following: ACK-high decoding margin, NACK-high decoding margin. It should be understood that these are all intended to be within the scope of the present application.

For other description of determining the indication information corresponding to the first data by the terminal device, please refer to the following embodiments, which are not repeated here. After determining the indication information corresponding to the first data, the terminal device may report the indication information corresponding to the first data to the network device, so that the network device can determine the channel quality of the PDSCH, and the like. Based on this, as shown in fig. 3, in an example, the method further includes step 220, where the terminal device sends indication information corresponding to the first data to the network device.

In summary, according to the technical solution provided in the embodiments of the present application, the indication information corresponding to the first data is determined for indicating the decoding margin situation of the terminal device for the first data by the terminal device for PDSCH transmission carrying the first data, and since the decoding margin situation may reflect the channel quality, the embodiments of the present application provide a way for determining the channel quality of the PDSCH. In addition, in the embodiment of the application, after the indication information corresponding to the first data is determined, the terminal device reports the indication information corresponding to the first data to the network device, so that the network device knows the decoding allowance condition of the terminal device for the first data, and accordingly, the channel quality of the PDSCH is mastered to further determine the transmission strategy and the like of the downlink data, and the transmission reliability and the transmission efficiency of the downlink data are improved.

In the following, several embodiments for determining the indication information corresponding to the first data are described. It should be understood that in the following several embodiments, the possible cases of the first data and the second data include at least the following:

(1) The first data includes at least one second data; the second data is a coding block; the first data is a transport block comprising at least one encoded block; alternatively, the first data is a set of code blocks including at least one code block.

(2) The first data includes at least one second data; the second data is a coding block group; the first data is a transport block comprising at least one set of encoded blocks.

(3) The first data includes at least one second data; the second data is a coding block; the first data is a transport block comprising at least one set of encoded blocks; wherein the at least one coding block is distributed in at least one coding block group.

In one possible implementation, the step 210 includes: if any second data included in the first data is incorrectly decoded, the terminal equipment determines that the indication information corresponding to the first data is NACK; if all the second data included in the first data are decoded correctly, the terminal equipment determines the indication information corresponding to the first data based on the indication information corresponding to the second data.

The first data comprises at least one second data and the terminal device may decode the at least one second data comprised by the first data. Optionally, the terminal device decodes the at least one second data in any order; alternatively, the terminal device decodes the at least one second data in a first order, which may be defined by the communication protocol, or may be configured (or indicated) by the network device; or the terminal device decodes the at least one second data in parallel.

In this embodiment, in the process of decoding, if any second data included in the first data is incorrectly decoded, the terminal determines that the indication information corresponding to the first data is NACK. It should be understood that any second data described in the embodiments of the present application includes any one second data, or includes any plurality of second data, which will not be described in detail in the following embodiments. At this time, if the first data has second data that are not decoded yet, the terminal device may not need to decode the second data that are not decoded, which helps to reduce the processing overhead of the terminal device. If all the second data included in the first data are decoded correctly, that is, if the terminal equipment decodes all the second data in the first data without the situation that the second data are decoded incorrectly, the terminal equipment determines the indication information corresponding to the first data based on the indication information corresponding to the second data. Optionally, the terminal device determines the indication information corresponding to the first data based on the indication information corresponding to all the second data; or the terminal equipment determines the indication information corresponding to the first data based on the indication information corresponding to part of the second data.

The terminal device may determine the indication information corresponding to the second data based on the reference information corresponding to the second data obtained in the process of decoding the second data, that is, in an example, the method further includes: the terminal equipment determines indication information corresponding to the second data based on the reference information corresponding to the second data. Optionally, the reference information includes at least one of: the number of decoding iterations, the decoding soft information, the inversion bits before and after LDPC (Low Density Parity Check ) decoding. The mode of determining the indication information by the terminal equipment based on the reference information is not limited, alternatively, a corresponding relation exists between the reference information and the indication information, and the terminal equipment can determine the indication information corresponding to the reference information based on the corresponding relation; alternatively, the indication information may be calculated from the reference information by a certain mathematical formula or the like.

Since all the second data in the first data are correctly decoded, the indication information corresponding to the second data may include an ACK-high decoding margin or an ACK-low decoding margin. Since the channel quality corresponding to the high decoding margin is better and the channel quality corresponding to the low decoding margin is worse under normal conditions, in order to obtain more accurate channel quality indication, the indication information corresponding to the first data is determined to be the high decoding margin only when all or most of the indication information corresponding to the second data included in the first data is the high decoding margin. However, the embodiment of the present application does not exclude the case where the indication information corresponding to the first data is determined to be the high decoding margin as long as the indication information corresponding to the second data is the high decoding margin. In the following, description will be made regarding several possible cases of determining the indication information corresponding to the first data based on the indication information corresponding to the second data.

In example (1), the determining, by the terminal device, the indication information corresponding to the first data based on the indication information corresponding to the second data includes: if all the indication information corresponding to the second data included in the first data is the ACK-high decoding allowance, the terminal equipment determines that the indication information corresponding to the first data is the ACK-high decoding allowance, otherwise, the terminal equipment determines that the indication information corresponding to the first data is the ACK-low decoding allowance. That is, if the indication information corresponding to any second data included in the first data is ACK-low decoding margin, the terminal device determines that the indication information corresponding to the first data is ACK-low decoding margin, otherwise the terminal device determines that the indication information corresponding to the first data is ACK-high decoding margin.

In example (2), the determining, by the terminal device, the indication information corresponding to the first data based on the indication information corresponding to the second data includes: if the corresponding indication information is that the duty ratio of the second data of the ACK-high decoding allowance in the first data is larger than a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-high decoding allowance; if the corresponding indication information is that the duty ratio of the second data of the ACK-high decoding allowance in the first data is smaller than or equal to a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-low decoding allowance; or if the corresponding indication information is that the duty ratio of the second data of the ACK-high decoding allowance in the first data is larger than or equal to a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-high decoding allowance; if the corresponding indication information is that the duty ratio of the second data of the ACK-high decoding allowance in the first data is smaller than a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-low decoding allowance. Alternatively, the first threshold may be defined by the communication protocol or may be configured by the network device. Alternatively, the first threshold is greater than or equal to 50%, e.g., the first threshold is 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, etc.

Illustratively, the number of bits occupied by the indication information is 2. As described in table one below, the correspondence between the value of the indication information and the content of the indication information provided by one embodiment of the present application is shown.

List one indication information

Value of indication information	Content of indication information
00	Reserved (Reserved)
01	NACK
10	ACK-low decoding margin
11	ACK-high decoding margin

Assuming that the first data includes 4 pieces of second data, the indication information corresponding to the 4 pieces of second data is respectively: 10. 11, 11. If, in the manner of the above example (1), the indication information corresponding to the second data is ACK-low decoding margin, since the second data included in the first data includes the indication information corresponding to the second data, the terminal device determines that the indication information corresponding to the first data is ACK-low decoding margin (10). If, as in the above example (2), the first threshold is assumed to be 50%, and the second data corresponding to the indication information being the ACK-high decoding margin has a 75% duty ratio in the first data, the terminal device determines that the indication information corresponding to the first data is the ACK-high decoding margin (11).

It should be noted that the following examples are not excluded in the embodiments of the present application.

In example (3), the determining, by the terminal device, the indication information corresponding to the first data based on the indication information corresponding to the second data includes: if all the indication information corresponding to the second data included in the first data is the ACK-low decoding allowance, the terminal equipment determines that the indication information corresponding to the first data is the ACK-low decoding allowance, otherwise, the terminal equipment determines that the indication information corresponding to the first data is the ACK-high decoding allowance. That is, if the indication information corresponding to any second data included in the first data is ACK-high decoding margin, the terminal device determines that the indication information corresponding to the first data is ACK-high decoding margin, otherwise the terminal device determines that the indication information corresponding to the first data is ACK-low decoding margin.

In example (4), the determining, by the terminal device, the indication information corresponding to the first data based on the indication information corresponding to the second data includes: if the corresponding indication information is that the duty ratio of the second data of the ACK-low decoding allowance in the first data is larger than a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-low decoding allowance; if the corresponding indication information is that the duty ratio of the second data of the ACK-low decoding allowance in the first data is smaller than or equal to a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-high decoding allowance; or if the corresponding indication information is that the duty ratio of the second data of the ACK-low decoding allowance in the first data is larger than or equal to a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-low decoding allowance; if the corresponding indication information is that the duty ratio of the second data of the ACK-low decoding allowance in the first data is smaller than a first threshold value, the terminal equipment determines that the indication information corresponding to the first data is the ACK-high decoding allowance. Alternatively, the first threshold may be defined by the communication protocol or may be configured by the network device. Alternatively, the first threshold is greater than or equal to 50%, e.g., the first threshold is 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, etc.

In another possible embodiment, the step 210 includes: if any second data included in the first data is incorrectly decoded, the terminal equipment determines that the indication information corresponding to the first data is NACK; if all the second data included in the first data are decoded correctly, the terminal equipment determines indication information corresponding to the first data based on the reference information corresponding to the second data.

In this embodiment, in the process of decoding, if any second data included in the first data is incorrectly decoded, the terminal determines that the indication information corresponding to the first data is NACK. At this time, if the first data has second data that are not decoded yet, the terminal device may not need to decode the second data that are not decoded, which helps to reduce the processing overhead of the terminal device. If all the second data included in the first data are decoded correctly, that is, if the terminal equipment decodes all the second data in the first data without the situation that the second data are decoded incorrectly, the terminal equipment determines indication information corresponding to the first data based on reference information corresponding to the second data. Optionally, the terminal device determines the indication information corresponding to the first data based on the reference information corresponding to all the second data; or the terminal equipment determines the indication information corresponding to the first data based on the reference information corresponding to part of the second data.

The terminal device may obtain the reference information corresponding to the second data in the process of decoding the second data, and further determine the indication information corresponding to the first data based on the reference information corresponding to the second data. In one example, the determining, by the terminal device, indication information corresponding to the first data based on the reference information corresponding to the second data includes: the terminal equipment determines the reference information corresponding to the first data based on the reference information corresponding to the second data; and determining indication information corresponding to the first data based on the reference information corresponding to the first data. Optionally, the terminal device determines the reference information corresponding to the first data based on the reference information corresponding to all the second data; or the terminal equipment determines the reference information corresponding to the first data based on the reference information corresponding to part of the second data. Optionally, the reference information includes at least one of: decoding iteration times, decoding soft information and turnover bits before and after LDPC decoding. The mode of determining the indication information by the terminal equipment based on the reference information is not limited, alternatively, a corresponding relation exists between the reference information and the indication information, and the terminal equipment can determine the indication information corresponding to the reference information based on the corresponding relation; alternatively, the indication information may be calculated from the reference information by a certain mathematical formula or the like.

The embodiment of the application does not limit the manner of determining the reference information corresponding to the first data based on the reference information corresponding to the second data. Several ways of determining are exemplarily described below.

In example (1), the determining, by the terminal device, the reference information corresponding to the first data based on the reference information corresponding to the second data includes: the terminal equipment takes the reference information meeting the first condition in the reference information corresponding to all the second data included in the first data as the reference information corresponding to the first data; the first condition includes a minimum value or a maximum value.

In example (2), the determining, by the terminal device, the reference information corresponding to the first data based on the reference information corresponding to the second data includes: the terminal equipment takes the average value of all the reference information corresponding to the second data included in the first data as the reference information corresponding to the first data; wherein the average value includes any one of: arithmetic mean, geometric mean, square mean (root mean square mean), harmonic mean, weighted mean.

In example (3), the determining, by the terminal device, the reference information corresponding to the first data based on the reference information corresponding to the second data includes: and the terminal equipment takes any reference information in the reference information corresponding to all the second data included in the first data as the reference information corresponding to the first data.

It should be noted that, when the reference information includes a plurality of types of content, the terminal device may determine, based on each type of content in the reference information corresponding to the second data, a corresponding type of content in the reference information corresponding to the first data. For example, the reference information includes a decoding iteration number and decoding soft information, the terminal device determines the decoding iteration number in the reference information corresponding to the first data (e.g., the decoding iteration number in the reference information corresponding to the first data is an average value of the decoding iteration numbers in the reference information corresponding to the second data) based on the decoding iteration number in the reference information corresponding to the second data, and determines the decoding soft information in the reference information corresponding to the first data (e.g., the decoding soft information in the reference information corresponding to the first data is an average value of the decoding soft information in the reference information corresponding to the second data) based on the decoding soft information in the reference information corresponding to the second data.

Illustratively, the reference information includes a number of decoding iterations, and the corresponding indication information is an ACK-low decoding margin when the reference information is greater than or equal to 5, and the corresponding indication information is an ACK-high decoding margin when the reference information is less than 5. Assuming that the first data includes 4 second data, all of the 4 second data are decoded correctly, and reference information corresponding to the 4 second data is respectively: the number of decoding iterations is 10, the number of decoding iterations is 1, and the number of decoding iterations is 1. If the reference information with the maximum value in the reference information corresponding to all the second data is used as the reference information corresponding to the first data, the reference information corresponding to the first data is 10, and the indication information corresponding to the first data is ACK-low decoding allowance because 10 is larger than 5. If the reference information with the minimum value in the reference information corresponding to all the second data is used as the reference information corresponding to the first data, the reference information corresponding to the first data is 1, and the indication information corresponding to the first data is ACK-high decoding allowance because the 1 is smaller than 5. If the average value of the reference information corresponding to all the second data is used as the reference information corresponding to the first data, the reference information corresponding to the first data is 3.25, and the indication information corresponding to the first data is ACK-high decoding margin because 3.25 is smaller than 5.

It should be understood that in the above two embodiments, the indication information includes any one of the following: ACK-high decoding margin, ACK-low decoding margin, NACK.

In summary, according to the technical solution provided in the embodiments of the present application, when the terminal device decodes the second data included in the first data, if the decoding of the second data is incorrect, it is determined that the indication information corresponding to the first data is NACK, and at this time, if the first data still includes the second data that is not decoded, the terminal device may not need to decode the second data that is not decoded, which is helpful to reduce the processing overhead of the terminal device. In addition, in the embodiment of the application, the terminal device can determine the indication information corresponding to the first data based on the reference information corresponding to the second data, and can also determine the indication information corresponding to the first data based on the indication information corresponding to the second data, so that various manners of determining the indication information corresponding to the first data are provided, and the flexibility of determining the indication information is improved.

In still another possible embodiment, the step 210 includes: the terminal equipment determines indication information corresponding to first data based on the indication information corresponding to second data, wherein the first data comprises at least one second data.

Optionally, the terminal device determines the indication information corresponding to the first data based on the indication information corresponding to all the second data; or the terminal equipment determines the indication information corresponding to the first data based on the indication information corresponding to part of the second data. The terminal device may determine the indication information corresponding to the second data based on the reference information corresponding to the second data obtained in the process of decoding the second data, that is, in an example, the method further includes: the terminal equipment determines indication information corresponding to the second data based on the reference information corresponding to the second data. Optionally, the reference information includes at least one of: the number of decoding iterations, the decoding soft information, the inversion bits before and after LDPC (Low Density Parity Check ) decoding. The mode of determining the indication information by the terminal equipment based on the reference information is not limited, alternatively, a corresponding relation exists between the reference information and the indication information, and the terminal equipment can determine the indication information corresponding to the reference information based on the corresponding relation; alternatively, the indication information may be calculated from the reference information by a certain mathematical formula or the like.

Since the second data may or may not be decoded correctly, the indication information corresponding to the second data may include any one of the following: ACK-high decoding margin, ACK-low decoding margin, NACK-high decoding margin, NACK-low decoding margin. Since the channel quality corresponding to the high decoding margin is better and the channel quality corresponding to the low decoding margin is worse under normal conditions, in order to obtain more accurate channel quality indication, the indication information corresponding to the first data is determined to be the high decoding margin only when all or most of the indication information corresponding to the second data included in the first data is the high decoding margin. However, the embodiment of the present application does not exclude the case where the indication information corresponding to the first data is determined to be the high decoding margin as long as the indication information corresponding to the second data is the high decoding margin.

In summary, according to the technical scheme provided by the embodiment of the application, under the condition that the second data included in the first data is incorrectly decoded, the determined indication information corresponding to the first data not only includes NACK, but also includes the decoding allowance, so that the content of the indication information is richer, and the reflected channel quality is more accurate. In addition, in the embodiment of the application, the terminal device can determine the indication information corresponding to the first data based on the reference information corresponding to the second data, and can also determine the indication information corresponding to the first data based on the indication information corresponding to the second data, so that various manners of determining the indication information corresponding to the first data are provided, and the flexibility of determining the indication information is improved.

The points to be described are: in the case that the second data is the coding block group, the determination mode of the reference information corresponding to the second data may refer to the determination mode of the reference information corresponding to the first data when the second data is the coding block, that is, the reference information corresponding to the coding block group may be determined based on the reference information corresponding to the coding block. When the second data is a coding block group, the determination mode of the indication information corresponding to the second data may refer to the determination mode of the indication information corresponding to the first data when the second data is a coding block, that is, the indication information corresponding to the coding block group may be determined based on the reference information corresponding to the coding block in the coding block group or may be determined based on the indication information corresponding to the coding block in the coding block group.

Since different coding block groups may occupy different time domain resources and/or different frequency domain resources, reporting an indication information to each coding block group may be equivalent to feedback of subband indication information to a certain extent, which improves the fine granularity of feedback, but may increase uplink overhead. Alternatively, in case the downlink data transmission comprises PDSCH transmission based on coded block groups, the terminal device may generate one indication information for all coded block groups, i.e. the second data is a coded block group and the first data is a transport block comprising at least one coded block group. Reporting an indication information through all the coding block groups can be equivalent to broadband indication information feedback to a certain extent, thereby saving uplink overhead, but sacrificing part of fine granularity of feedback.

The following points are also to be described: the above embodiment describes the transmission method of the indication information provided in the embodiment of the present application from the aspect of interaction between the terminal device and the network device. The steps executed by the related terminal equipment can be independently implemented as a transmission method of indication information of the terminal equipment side; the steps described above with respect to the execution of the network device may be implemented separately as a method for transmitting the indication information on the network device side.
