The network architecture and service scenarios described in the embodiments of the present application are for the purpose of illustrating the technical solutions of the embodiments of the present application more clearly, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. The evolution of new business scenarios and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

First, some terms and related technologies involved in the embodiments of the present application are briefly introduced.

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

For PDSCH transmission based on TB (Transport Block, transport block), the terminal device receives the PDSCH sent by the network device, and feeds back HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat request)-ACK (Acknowledgement, positive confirmation) for this PDSCH. Wherein, when a TB is correctly demodulated, the terminal device generates ACK bits; when the TB is not correctly demodulated, the terminal device generates NACK (Negative Acknowledgement, negative acknowledgment) bits.

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

For CBG-based PDSCH transmission, if all CBs in the CBG are correctly received, the terminal device generates ACK bits for the CBG; if there is at least one CB with demodulation error in the CBG, the terminal device generates the ACK bit for the CBG. is the NACK bit.

2. Channel State Information (CSI)

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

In Rel-15 and Rel-16 of the NR system, CSI is acquired and reported to the network device based on the measurement of the CSI-RS resources by the terminal device. In Rel-15 and Rel-16, CSI reporting is divided into: periodic reporting of CSI, semi-persistent reporting of CSI, and aperiodic reporting of CSI according to time domain features.

Periodic reporting of CSI: The network device configures the period and offset of reporting CSI for the terminal device through RRC (Radio Resource Control, Radio Resource Control) signaling. After the terminal device receives the RRC signaling, the PUCCH (Physical Uplink Control Channel, the physical uplink control channel) periodically reports CSI.

Semi-persistent reporting of CSI: When the terminal device reports CSI semi-persistently through PUCCH, the network device activates/deactivates CSI through MAC (Medium Access Control, medium access control) CE (Control Element, control unit) signaling After the MAC CE signaling activates the reporting of CSI, the terminal device periodically reports the CSI on the PUCCH; when the terminal device reports the CSI semi-continuously through the PUSCH (Physical Uplink Shared Channel) , the network device activates/deactivates the reporting of CSI through DCI (Downlink Control Information, downlink control information), and after the DCI activates the reporting of CSI, the terminal device periodically reports CSI on the PUSCH.

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

In some implementations, the channel/interference measurement resource used to report CSI at slot n (slot n) cannot be later than the CSI reference resource slot nn _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 than

For aperiodic reporting of CSI, n _CSI-ref needs to be greater than the CSI calculation time, where the CSI calculation time is much greater than the PDSCH decoding time.

In order to meet the two characteristics of low latency and high reliability of the URLLC service at the same time (for example, to ensure that the number of transmissions of the URLLC service within the allowable delay range can meet the reliability requirements), it is necessary for the terminal equipment to report a more accurate reflection of the channel quality. Channel state information to assist the network device to better perform initial transmission and/or retransmission scheduling. In an example, more accurate channel state information can be reported in the following manner.

(1) The period of periodic/semi-persistent reporting of CSI is configured to be very short;

(2) Use DCI to trigger aperiodic reporting of CSI.

For method (1), network equipment needs to send CSI-RS resources at a high density in order to obtain rapidly updated channel state information, which increases the system reference signal (CSI-RS resource) overhead on the one hand, and increases the The measurement and calculation overhead of the terminal equipment is reduced. At the same time, 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 periodic/semi-persistent CSI reported in the uplink time slot n, the CSI reference resource is the earliest. CSI-RS transmitted for slot n-4 (assume: UL (Uplink, uplink) and DL (Downlink, downlink) have the same subcarrier spacing, and only one CSI-RS resource is configured for channel measurement ), and the interference received by the terminal equipment is greatly affected by neighboring cell scheduling. Due to the long measurement time, the interference that the terminal equipment may receive when reporting CSI has changed, resulting in inaccurate CSI.

For mode (2), the network device needs to send DCI to trigger the transmission of CSI-RS and the reporting of CSI. On the one hand, the DCI used to trigger CSI reporting can only be the DCI (UL DCI) that schedules the PUSCH, and the terminal device may go up and down In this case, in order to trigger CSI reporting, UL DCI will be wasted; on the other hand, for aperiodic reporting of CSI, the terminal equipment starts from receiving UL DCI to sending CSI. The processing time is also very long. For services with urgent delay, if the initial transmission is wrong and the delay requirement cannot tolerate CSI reporting, the network equipment can only use a very conservative MCS (Modulation and Coding Scheme, modulation and coding strategy) for scheduling , 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 at the same time improve the transmission efficiency of the system, PDSCH-based demodulation and/or measured channel state information is proposed in Rel-17. Obtaining channel state information based on PDSCH demodulation and/or measurement can not only save CSI-RS resources, but also reduce computing power consumption and processing delay of terminal equipment, which can better meet the requirements of URLLC services.

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

It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (Long Term Evolution, LTE) system, LTE Frequency Division Duplex (Frequency Division Duplex, FDD) system, LTE Time Division Duplex ( Time Division Duplex, TDD) system, Advanced Long Term Evolution (LTE-A) system, NR system, evolution system of NR system, LTE (LTE-based access to Unlicensed spectrum, LTE- U) systems, NR-U (New Radio-Unlicensed, NR on unlicensed bands) systems, Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communications system, etc.

Please refer to FIG. 2 , which shows a flowchart of a method for determining indication information provided by an embodiment of the present application, and the method can be applied to the communication system shown in FIG. 1 above. The method may include at least some of the following steps.

Step 210, the terminal device determines the indication information corresponding to the first data based on the PDSCH, where the indication information corresponding to the first data is used to indicate the 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, and 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, if the first data is a transport block (TB), then the PDSCH transmission based on the first data is PDSCH transmission based on the transport block; or, if the first data is a coding block group (CBG), then the first data-based PDSCH transmission is PDSCH transmission is PDSCH transmission based on coded block groups. In some implementations, in order to reduce the complexity of data encoding and/or data decoding, the input bit length of the encoder and/or decoder is limited, based on this, the number of bits included in the first data exceeds a threshold When the value is set, the terminal device will perform code block division on the first data to obtain at least one second data. Optionally, when the first data is a transport block, the second data is a coding block (CB) or a coding block group; when the first data is a coding block group, the second data is a coding block. Below, several possible examples of the first data and the second data are exemplarily introduced.

Exemplarily, the first data includes at least one second data; the second data is an encoding block; the first data is a transport block including at least one encoding block; or the first data is an encoding block group including at least one encoding block.

Exemplarily, the first data includes at least one second data; the second data is an encoding block group; the first data is a transport block including at least one encoding block group.

Exemplarily, the first data includes at least one second data; the second data is an encoding block; the first data is a transport block including at least one encoding block group; wherein the at least one encoding block is distributed in the at least one encoding block group.

In this embodiment of the present application, the PDSCH transmission based on the first data may reflect the channel quality of the PDSCH through the decoding margin for the first data. Based on this, in order to determine the channel quality of the PDSCH, the terminal device may determine the indication information corresponding to the first data when receiving the downlink data transmission from the network device, or after receiving the downlink data transmission from the network device. The indication information corresponding to the first data is used to indicate the decoding margin situation of the terminal device for the first data. This embodiment of the present application does not limit the number of bits occupied by the indication information. Optionally, 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 situation can be divided into high decoding margin and low decoding margin. Generally, a high decoding margin reflects better channel quality, and a low decoding margin reflects poor channel quality. Of course, the embodiments of the present application do not exclude the possibility that a high decoding margin reflects poor channel quality, and a low decoding margin reflects better channel quality. In addition, the decoding results can generally be divided into correct decoding (the terminal device generates ACK bits) and incorrect decoding (the terminal device generates NACK bits).

Based on this, in an example, the decoding margin condition for the first data includes any one of the following: correct decoding and high decoding margin, correct decoding and low decoding margin, incorrect decoding and high decoding margin, and incorrect decoding Correct and low decoding margin, thus, 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 condition for the first data includes any one of the following: correct decoding and high decoding margin, correct decoding and low decoding margin, and incorrect decoding, so that the indication information corresponding to the first data Including any one of the following: ACK-high decoding headroom, ACK-low decoding headroom, NACK; in yet another example, the decoding headroom condition for the first data includes any one of the following: decoding is correct, decoding is incorrect, and High decoding margin, incorrect decoding, and low decoding margin, therefore, the indication information corresponding to the first data includes any one of the following: ACK, NACK-high decoding margin, and NACK-low decoding margin.

Of course, the decoding margin for the first data may only include any one of the following: high decoding margin, low decoding margin, and thus, the indication information corresponding to the first data includes any of the following: high decoding margin, low decoding margin Decoding margin. After understanding the technical solutions provided by the embodiments of the present application, those skilled in the art may also think of other implementation manners. For example, the decoding margin for the first data includes any of the following: correct decoding and high decoding margin, The decoding fails and the decoding margin is high, so the indication information corresponding to the first data includes any one of the following: ACK-high decoding margin, NACK-high decoding margin. It should be understood that these should all fall within the protection scope of the present application.

For other descriptions of the terminal device determining the indication information corresponding to the first data, please refer to the following embodiments, and details 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 specify the channel quality of the PDSCH and the like. Based on this, as shown in FIG. 3 , in an example, the above method further includes step 220 , the terminal device sends indication information corresponding to the first data to the network device.

To sum up, in the technical solutions provided by the embodiments of the present application, the terminal device determines the indication information corresponding to the first data for the PDSCH transmission carrying the first data, so as to indicate the decoding margin situation of the terminal device for the first data, Since the decoding margin situation can reflect the channel quality, the embodiment of the present application provides a way to determine the channel quality of the PDSCH. In addition, in this embodiment of the present application, after determining the indication information corresponding to the first data, the terminal device reports the indication information corresponding to the first data to the network device, so that the network device can know the decoding margin of the terminal device for the first data , so as to grasp the channel quality of the PDSCH to further determine the transmission strategy of the downlink data, etc., which helps to improve the transmission reliability and transmission efficiency of the downlink data.

Hereinafter, several implementation manners for determining the indication information corresponding to the first data will be introduced. It should be understood that, in the following embodiments, the possible situations 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 an encoding block; the first data is a transport block including at least one encoding block; or the first data is an encoding block group including at least one encoding block.

(2) The first data includes at least one second data; the second data is an encoding block group; the first data is a transport block including at least one encoding block group.

(3) The first data includes at least one second data; the second data is an encoding block; the first data is a transport block including at least one encoding block group; wherein the at least one encoding block is distributed in the at least one encoding block group.

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

The first data includes at least one second data, and the terminal device can decode the at least one second data included in the first data. Optionally, the terminal device decodes the at least one second data in any order; or, the terminal device decodes the at least one second data in a first order, and the first order may be defined by a communication protocol, or may be defined by a network device configuration (or indication); or, the terminal device performs parallel decoding on the at least one second data.

In this embodiment, during the decoding process of the terminal device, if any second data included in the first data is decoded incorrectly, the terminal device 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 second data, or includes any plurality of second data, which will not be repeated in the following embodiments. At this time, if there is still undecoded second data in the first data, the terminal device may not need to decode the undecoded second data, which will help reduce the processing overhead of the terminal device. If all the second data included in the first data are decoded correctly, that is, the terminal device has decoded all the second data in the first data without decoding the second data incorrectly, then the terminal device based on the second data corresponding to the The indication information is to determine the indication information corresponding to the first 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 device 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 above method further includes: the terminal device based on the second data The reference information corresponding to the data is used to determine the indication information corresponding to the second data. Optionally, the reference information includes at least one of the following: decoding iteration times, decoding soft information, and flipped bits before and after LDPC (Low Density Parity Check, Low Density Parity Check) decoding. This embodiment of the present application does not limit the manner in which the terminal device determines the indication information based on the reference information. Optionally, there is a correspondence between the reference information and the indication information, and based on the correspondence, the terminal device can determine the indication information corresponding to the reference information. ; Or, the indication information can be calculated based on the reference information through a certain mathematical formula or the like.

Since all the second data in the first data are decoded correctly, the indication information corresponding to the second data may include ACK-high decoding margin or ACK-low decoding margin. In general, high decoding margin corresponds to better channel quality, and low decoding margin corresponds to poor channel quality. Therefore, in order to obtain a more accurate channel quality indication, all the second data included in the first data or most of the first data The indication information corresponding to the first data is determined to be a high decoding margin only when the indication information corresponding to the two data is both high decoding margin. However, the embodiment of the present application does not exclude the situation that the indication information corresponding to the first data is determined to be a high decoding margin as long as the indication information corresponding to the second data is high decoding margin. Hereinafter, several possible situations in which the indication information corresponding to the first data is determined based on the indication information corresponding to the second data will be described.

In example (1), the terminal device determines the indication information corresponding to the first data based on the indication information corresponding to the second data, including: if the indication information corresponding to all the 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 the ACK-high decoding margin, otherwise the terminal device determines that the indication information corresponding to the first data is the ACK-low decoding margin. 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 the first data The indication information corresponding to a piece of data is ACK-high decoding margin.

In example (2), the terminal device determines the indication information corresponding to the first data based on the indication information corresponding to the second data, including: if the corresponding indication information is ACK-high decoding margin of the second data in the first data If the proportion of the first data is greater than the first threshold, the terminal device determines that the indication information corresponding to the first data is the ACK-high decoding margin; if the corresponding indication information is the ACK-high decoding margin of the second data in the first data If the proportion is less than or equal to the first threshold, the terminal device determines that the indication information corresponding to the first data is ACK-low decoding margin; or, if the corresponding indication information is ACK-high decoding margin for the second data in the first data If the proportion of ACK is greater than or equal to the first threshold, the terminal device determines that the indication information corresponding to the first data is ACK-high decoding margin; if the corresponding indication information is ACK-high decoding margin, the second data is in the first data If the proportion of the first data is less than the first threshold, the terminal device determines that the indication information corresponding to the first data is ACK-low decoding margin. Optionally, the first threshold may be defined by a communication protocol or configured by a network device. Optionally, the first threshold is greater than or equal to 50%, for example, the first threshold is 95%, 90%, 85%, 80%, 75%, 70%, 65%, 60%, 55%, 50%, and so on.

Exemplarily, the number of bits occupied by the indication information is 2. As described in Table 1 below, it shows the corresponding relationship between the value of the indication information provided by an embodiment of the present application and the content of the indication information.

0000	Reserved(保留)Reserved
0101	NACK NACK

Assuming that the first data includes four pieces of second data, the indication information corresponding to the four pieces of second data are: 10, 11, 11, and 11, respectively. If according to the above example (1), since the second data included in the first data contains the indication information corresponding to the second data as ACK-low decoding margin, the terminal device determines that the indication information corresponding to the first data is ACK- Low decoding margin (10).
