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. 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.

At present, in related technologies of NR systems, CSI is obtained based on measurement of CSI-RS resources by a terminal device and reported to a network device, and specifically, 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 slots 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.

2. MCS (Modulation and Coding Scheme, modulation and coding strategy) table.

Both the uplink and downlink of the NR system support 3 MCS tables of 256QAM (Quadrature Amplitude Modulation ), 64QAM and lowSE64QAM, respectively.

At the beginning of NR system design, only two MCS tables of 256QAM and 64QAM are supported, the target BLER (Block Error Rate) is 1e-1, and the purpose is to support eMBB (Enhanced Mobile Broadband ) service, and later, in order to better support URLLC service, a lowSE64QAM MCS table is designed, and the target BLER is 1e-5. When the subcarrier spacing is smaller (for example, the subcarrier spacing is 15kHz (kilohertz), the symbol/slot time corresponding to the subcarrier spacing is longer), and the delay and reliability requirements of the URLLC service are higher, in this case, because the delay of the URLLC service is urgent, the high reliability of the URLLC cannot be satisfied by repeating transmission/retransmission multiple times, but the reliability of 1e-5 is satisfied by a single transmission, and therefore, the target BLER of the MCS table of lowSE64QAM is 1e-5.

In an actual network implementation, when the subcarrier spacing of the serving cell is larger (the symbol/slot corresponding to the subcarrier spacing is shorter), or the delay of the URLLC service allows retransmission/retransmission, the network device typically includes: firstly, scheduling primary transmission by using MCS with a target BLER of 1 e-1; if the initial transmission fails, the retransmission is scheduled with an MCS, e.g., with a target BLER of 1e-5, to ensure that the packet is received correctly within two transmissions. The terminal device may determine an MCS table used for receiving/transmitting the downlink/uplink data packet according to configuration information and/or indication information of the network device.

3. Physical layer priority.

In the NR system, in order to better support the URLLC service, a high priority and a low priority are introduced in the physical layer for the uplink channel. Wherein, priority index 0 (priority index is 0) indicates a low priority, and priority index 1 (priority index is 1) indicates a high priority. The terminal device may determine the priority index of the uplink channel (uplink channel includes PUSCH and PUCCH) according to the configuration information and/or the indication information of the network device.

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/n-5 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 affected by the scheduling of the adjacent cells, and due to the long measurement time, the interference possibly suffered by the terminal equipment when reporting 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 by the terminal device is long, and for the service with urgent delay, if the initial transmission is wrong and the delay requirement cannot tolerate CSI reporting, the network device can only use a very conservative MCS 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 at the same time improve the transmission efficiency of the system, a new type of channel state information is proposed, such as channel state information based on demodulation and/or measurement of PDSCH, or called "reporting of delta MCS (reporting of MCS difference)". Where delta MCS is the difference between the target MCS and the reference MCS, the target MCS is the maximum MCS such that the prediction BLER (estimated BLER) of the TB (Transport Block) received using the MCS is less than or equal to the target BLER. Because the channel state information is obtained based on the demodulation and/or measurement of the PDSCH, no extra measurement resources and no extra measurement time are needed, the calculation time delay and the power consumption for obtaining the channel state information by the terminal equipment can be reduced based on the demodulation and/or the measurement of the PDSCH, and meanwhile, the CSI-RS resources can be saved, so that the system has more resources to transmit downlink data, and the network capacity is improved.

However, how the terminal device determines the target BLER to further determine the target MCS and to obtain the channel quality of the communication link in a manner based on the demodulation and/or measurement of the PDSCH to obtain the channel state information has not been mentioned and discussed at present. Based on this, the embodiment of the application provides an information reporting method, which can be used for solving the technical problems.

In the embodiment of the present application, the following two principles are considered for the determination of the target BLER.

(1) The target BLER needs to be such that the quantization overhead of the delta-MCS is as small as possible. One way to make the quantization overhead of delta-MCS as small as possible is to get the target BLER of delta-MCS and the BLER of the network device scheduling data packet as close as possible. For example, as shown in fig. 1, if the BLER of the network device scheduling data packet is the same as the target BLER of the delta-MCS obtained by the terminal device, the delta-MCS range is smaller, and the corresponding quantization overhead is smaller (or, in other words, the quantization error of the delta-MCS is smaller in the case of the same overhead); if the BLER of the network device scheduling packet is different from the target BLER of the delta-MCS obtained by the terminal device, the delta-MCS range is larger, and the corresponding quantization overhead is larger (or, in other words, the delta-MCS quantization error is larger in the case of the same overhead).

(2) The target BLER should be as closely matched as possible to the BLER used by the next scheduling of the network device to minimize the complexity of the implementation algorithm by which the network device gets the MCS used by the next scheduling based on the reported delta-MCS. It is assumed that if the delta-MCS reported by the terminal device is based on a target BLER of 1e-5 and the BLER used by the network device for the next scheduling is 1e-1, then the network device needs to make a target BLER conversion at the time of MCS selection, which not only results in additional algorithm complexity, but also results in a compromise in the accuracy of the target BLER conversion due to the non-linearity of the MCS-SINR (Signal to Interference plus Noise Ratio ) curves of different BLERs.

In the following, the technical solutions of the present application will be described in connection with several embodiments.

Referring to fig. 2, 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 terminal device 10 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), mobile Station (MS), and the like, having wireless communication capabilities. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a terminal device.

The network device 20 is a means deployed in the access network to provide wireless communication functionality for the terminal device 10. 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. 3, a flowchart of an information reporting method according to an embodiment of the present application is shown, and the method may be applied to the communication system shown in fig. 2. The method may comprise at least part of the following steps.

Step 310, the terminal device determines first feedback information based on the information related to the first PDSCH; the first feedback information is derived based on a target BLER, which is related to information related to the first PDSCH.

The first PDSCH may be a PDSCH configured by the network device through higher layer signaling, optionally, the higher layer signaling includes at least one of: SIB (System Information Block, system message block), RRC, MAC; alternatively, the first PDSCH may be a PDSCH scheduled by the network device through DCI.

The content of the information related to the first PDSCH is not limited in this embodiment, and optionally, the information related to the first PDSCH includes at least one of the following: the method includes the steps of a serving cell where a first PDSCH is located, HARQ-ACK (Hybrid Automatic Repeat Request) information corresponding to the first PDSCH, a priority index of an uplink channel carrying the HARQ-ACK information corresponding to the first PDSCH, the first PDSCH being an initial transmission or retransmission, NDI (New Data Indication ) corresponding to the first PDSCH being flipped or not flipped, and a first indication field in DCI for scheduling or activating the first PDSCH, the first indication field being used for indicating a target BLER on which the first feedback information is based, that is, the target BLER for determining the first feedback information is indicated by the first indication field.

For the determination that the first PDSCH is the primary transmission or the retransmission, the first PDSCH may be determined to be the primary transmission or the retransmission based on different manners of determining the first PDSCH. In one example, the first PDSCH is a PDSCH configured by the network device through higher layer signaling, and may default to initial transmission. Optionally, the higher layer signaling includes at least one of: SIB, RRC, MAC. In another example, the first PDSCH is a PDSCH scheduled by the network device through DCI, and the first PDSCH may be determined to be a primary transmission or a retransmission based on whether the NDI included in the DCI is flipped. Optionally, in the case that an NDI corresponding to the first PDSCH (i.e., an NDI included in DCI for scheduling the first PDSCH) is flipped with respect to the first NDI, the first PDSCH is primary transmission; under the condition that the NDI corresponding to the first PDSCH is not overturned relative to the first NDI, the first PDSCH retransmits; the first NDI is an NDI corresponding to a previous transmission of a TB carrying the first PDSCH. Or, it can be said that, in the case where the NDI corresponding to the first PDSCH is flipped with respect to the NDI corresponding to the previous transmission of the same TB, the first PDSCH is the primary transmission; and in the case that the NDI corresponding to the first PDSCH is not flipped relative to the NDI corresponding to the previous transmission of the same TB, retransmitting the first PDSCH. Wherein, the "previous transmission" in the "previous transmission of the same TB" is carried in the same TB as the "transmission of the first PDSCH".

For other description of the information related to the first PDSCH, please refer to the following embodiments, which are not repeated here.

The terminal device may determine first feedback information for estimating channel quality and/or channel characteristics of the communication link based on the first PDSCH related information. In this embodiment of the present application, the terminal device may determine the target BLER first based on the information related to the first PDSCH, and then determine the first feedback information further based on the target BLER.

The content of the first feedback information is not limited, and in one example, the first feedback information includes channel state information obtained based on demodulation and/or measurement of the first PDSCH; alternatively, the first feedback information includes a first difference value, which is a difference value between the target MCS and the reference MCS. The target MCS is an MCS obtained based on the target BLER, the terminal equipment can firstly determine the target BLER based on the information related to the first PDSCH, and then further determine the target MCS based on the target BLER, wherein the target MCS is a maximum MCS which enables the predicted BLER of the TB received by using the MCS to be smaller than or equal to the target BLER; the reference MCS corresponds to the first PDSCH or is configured by the network device or predefined by the communication protocol. Optionally, the MCS corresponding to the first PDSCH is an MCS included in DCI for scheduling the first PDSCH.

It should be understood that the name "first feedback information" may vary, for example, the "first feedback information" may also be referred to as "channel state information", or as "new channel state information", or as "reporting of delta MCS (reporting of MCS difference), or as" case-2reporting ". For convenience of description, information for estimating channel quality and/or channel characteristics of a communication link, which is obtained based on PDSCH-related information, will be collectively referred to as "first feedback information".

For other description of determining the first feedback information by the terminal device based on the information related to the first PDSCH, please refer to the following embodiments, which are not repeated here.

In step 320, the terminal device sends the first feedback information to the network device.

After obtaining the first feedback information, the terminal device may send the first feedback information to the network device, so as to indicate the channel quality and/or the channel characteristic of the communication link to the network device, thereby providing a reference for downlink transmission and the like for the network device. Optionally, the terminal device sends the first feedback information to the network device through the PUCCH resource.

The reporting manner of the first feedback information is not limited in the embodiment of the present application. In an example, when the terminal device sends the first feedback information to the network device, the terminal device reports the first feedback information as separate uplink information to the network device, where the terminal device may report the first feedback information and other uplink information (such as HARQ-ACK codebook) at the same time, or may not report the first feedback information and other uplink information (such as HARQ-ACK codebook) at the same time. In another example, the terminal device combines the first feedback information with other uplink information (e.g., HARQ-ACK codebook) and reports the combined first feedback information to the network device.

In summary, according to the technical scheme provided by the embodiment of the application, the feedback information is determined based on the information related to the PDSCH through the terminal device, and the feedback information is reported to the network device, so that the channel quality and/or the channel characteristic of the communication link are indicated to the network device, and additional measurement resources and measurement time for the communication link are not needed, so that the calculation time delay and the power consumption of the terminal device for obtaining the information related to the channel state are reduced, meanwhile, the CSI-RS resources are saved, so that the communication system has more resources for transmitting downlink data, and the network capacity is improved. In addition, in the embodiment of the present application, the feedback information is information that is determined based on the target BLER and is used to reflect the channel state, and the terminal device may determine the target BLER based on the information related to the PDSCH, thereby providing a manner of determining the target BLER. In addition, because the determination of the target BLER is based on the information related to the PDSCH, the matching between the target BLER and the PDSCH can be realized, so that the accuracy of the target BLER is ensured, the accuracy of feedback information is improved, and the effect of providing accurate indication of the channel state for the network equipment is achieved.

Next, a procedure of determining the first feedback information by the terminal device based on the first PDSCH will be described.

In one example, the first PDSCH related information includes: a serving cell in which the first PDSCH is located; the step 310 includes: the terminal equipment determines first feedback information based on n reference BLER corresponding to a serving cell where a first PDSCH is located, wherein n is equal to 1 or n is an integer greater than 1.

Since the subcarrier spacing of the active BWP (Bandwidth Part) of different serving cells is different, the number of transmission times that can be tolerated for transmission on different serving cells is different even for the same service. For example, for URLLC traffic, only a single transmission can be allowed on a serving cell with a subcarrier spacing of 15kHz, i.e. the network device needs to schedule with a BLER of 1e-5 per scheduling packet; on a serving cell with a subcarrier spacing of 60kHz, two transmissions may be allowed, i.e. the network device may schedule the initial transmission with a BLER of 1e-1 to improve the transmission efficiency, and schedule the retransmission with a BLER of 1e-5 if the initial transmission is wrong to ensure the reliability. Based on this, in the embodiment of the present application, different reference BLERs are set for different serving cells, and by setting the reference BLER for each serving cell (per-serving cell), the target BLER determined by the terminal device may be matched with the BLER used by the network device for scheduling the data packet as much as possible, so as to reduce quantization overhead.

Taking the serving cell where the first PDSCH is located as an example, the serving cell where the first PDSCH is located sets n reference BLERs corresponding to the serving cell. Alternatively, the n reference BLERs may be configured by the network device, e.g. the network device sends the n reference BLERs to the terminal device; may also be predefined by the communication protocol. In one example, the reference BLER is a BLER, or the reference BLER is a value, e.g., the reference BLER is 1e-5, or the reference BLER is 1e-1. In another example, the reference BLER is a set comprising at least one BLER, e.g., the reference BLER is {1e-1}, or the reference BLER is {1e-1,1e-5}.

Optionally, in the case that the subcarrier spacing of the serving cell where the first PDSCH is located for activating BWP is smaller than the first threshold, n reference BLERs are all values; in case that the subcarrier spacing of the serving cell activated BWP where the first PDSCH is located is greater than the first threshold, at least one of the n reference BLERs is a set including at least one BLER. In the embodiment of the present application, the first threshold is not limited, for example, the first threshold is set to 30kHz, and if the subcarrier interval of the serving cell where the first PDSCH is located for activating BWP is set to 15kHz, the n reference BLERs may include 1e-1 and 1e-5; assuming that the subcarrier spacing of the serving cell active BWP where the first PDSCH is located is 60kHz, the n reference BLER may include {1e-1} and {1e-1,1e-5}.

The terminal device may determine n reference BLERs corresponding to the serving cell in which the first PDSCH is located based on the serving cell in which the first PDSCH is located, and further determine the first feedback information based on the n reference BLERs. In this embodiment of the present application, the terminal device may determine the target BLER first based on the n reference BLERs, and then determine the first feedback information further based on the target BLER.

It should be understood that in the embodiment of the present application, n may be equal to 1, where the serving cell where the first PDSCH is located corresponds to only one reference BLER, and if the reference BLER is a value or is a set including only one BLER, the terminal device may directly use the reference BLER as the target BLER; if the reference BLER is a set comprising a plurality of BLERs, the terminal device may further select one BLER from the plurality of BLERs as the target BLER based on other information, or the terminal device may randomly select one BLER from the plurality of BLERs as the target BLER. In this embodiment of the present application, n may also be greater than 1, where a serving cell where the first PDSCH is located corresponds to multiple reference BLERs, and the terminal device may further select the target BLER from the multiple BLERs based on other information. For the procedure of selecting the target BLER by the terminal device based on other information, please refer to the following embodiments, which are not repeated here.

In another example, the first PDSCH related information includes: a priority index of an uplink channel carrying HARQ-ACK information corresponding to the first PDSCH; the step 310 includes: under the condition that the priority index of the uplink channel is a first priority index, the terminal equipment determines first feedback information based on a first reference BLER in n reference BLER; and under the condition that the priority index of the uplink channel is the second priority index, the terminal equipment determines the first feedback information based on the second reference BLER in the n reference BLER.

A reasonable network device implementation is: for eMBB traffic, the network device uses a BLER of 1e-1 for scheduling; whereas for URLLC traffic the network device uses a BLER of 1e-5 for scheduling. Thus, associating the target BLER with physical layer priorities may enable the target BLER to be matched as much as possible to the BLER used by the network device to schedule the data packets to reduce quantization overhead. Based on this, in the embodiment of the present application, different reference BLERs are set for different physical layer priorities.

The terminal device may determine a corresponding reference BLER based on the priority index of the uplink channel, and further determine the first feedback information based on the reference BLER. In one example, the priority index of the uplink channel is configured by the network device through a higher layer signaling, where the higher layer signaling is used to configure the first PDSCH, or, in other words, when the network device configures the first PDSCH for the terminal device through the higher layer signaling, the priority index of the uplink channel carrying HARQ-ACK information corresponding to the first PDSCH is configured through the higher layer signaling at the same time. Optionally, the higher layer signaling includes at least one of: SIB, RRC, MAC. In another example, the priority index of the uplink channel is indicated by the DCI for the network device to schedule or activate the first PDSCH.

In this embodiment of the present application, the priority index of the uplink channel includes a first priority index and a second priority index, and when the priority index of the uplink channel is the first priority index, the terminal device determines a first reference BLER corresponding to the first priority index from n reference BLERs, and further determines first feedback information based on the first reference BLER; and under the condition that the priority index of the uplink channel is the second priority index, the terminal equipment determines a second reference BLER corresponding to the second priority index from the n reference BLER, and further determines the first feedback information based on the second reference BLER.

It should be understood that in the embodiment of the present application, n may be equal to 1, where the first reference BLER is the same as the second reference BLER, that is, no matter what priority index the priority index of the uplink channel is, the terminal device determines the first feedback information based on the same reference BLER. In this embodiment of the present application, n may also be greater than 1, where the first reference BLER and the second reference BLER are implemented as different reference BLERs in the n reference BLERs, that is, the priority index of the uplink channel is different, and the terminal device determines the first feedback information based on the different reference BLERs.

Furthermore, in the embodiment of the present application, the first reference BLER/second reference BLER may be a value or a set including only one BLER, so that the terminal device may directly take the first reference BLER/second reference BLER as the target BLER and determine the first feedback information further based on the target BLER. In this embodiment of the present application, the first BLER/second BLER may also be a set including a plurality of BLERs, so that the terminal device may further select one BLER from the plurality of BLERs as the target BLER based on other information, or the terminal device may randomly select one BLER from the plurality of BLERs as the target BLER. For the procedure of selecting the target BLER by the terminal device based on other information, please refer to the following embodiments, which are not repeated here.

Taking the first reference BLER and the second reference BLER as values, and assuming that the physical layer priority corresponding to the first priority index is higher than the physical layer priority corresponding to the second priority index, the first reference BLER determined by the terminal device based on the first priority index is smaller than the second reference BLER; assuming that the physical layer priority corresponding to the first priority index is lower than the physical layer priority corresponding to the second priority index, the first reference BLER determined by the terminal device based on the first priority index is greater than the second reference BLER. For example, assuming that the first priority index is the priority index 1 and the second priority index is the priority index 0, the first reference BLER is 1e-5 and the second reference BLER is 1e-1; assuming that the first priority index is the priority index 0 and the second priority index is the priority index 1, the first reference BLER is 1e-1 and the second reference BLER is 1e-5.

Taking the first reference BLER as a value or set and the second reference BLER as a value or set as an example, assuming that the physical layer priority corresponding to the first priority index is higher than the physical layer priority corresponding to the second priority index, the first reference BLER determined by the terminal device based on the first priority index is smaller than or equal to the second reference BLER; assuming that the physical layer priority corresponding to the first priority index is lower than the physical layer priority corresponding to the second priority index, the first reference BLER determined by the terminal device based on the first priority index is greater than or equal to the second reference BLER. For example, assuming that the first priority index is the priority index 1 and the second priority index is the priority index 0, the first reference BLER is {1e-1,1e-5}, and the second reference BLER is {1e-1} or 1e-1; assuming that the first priority index is the priority index 0 and the second priority index is the priority index 1, the first reference BLER is {1e-1} or 1e-1, and the second reference BLER is {1e-1,1e-5}.

In yet another example, the first PDSCH related information includes: a first indication field in DCI for scheduling or activating a first PDSCH; the step 310 includes: under the condition that the value of the first indication domain is the ith value, the terminal equipment determines first feedback information based on the ith reference BLER in the n reference BLER; i is a positive integer less than or equal to n.

The first PDSCH may be a PDSCH scheduled by the network device through DCI, in which, in this example, a first indication field in the DCI may be used to indicate a target BLER on which the first feedback information is determined. The first indication field may be an existing information field in the multiplexed DCI or may be a newly defined information field in the DCI, which is not limited in the embodiment of the present application. The number of bits in the first indication field may be 1 bit, or may be multiple bits, such as 2 bits, 3 bits, 4 bits, or the like, which is not limited in this embodiment. Illustratively, the first indication field is 1 bit, and the value of the first indication field may be 0 or 1; the first indication field is 2 bits, and the value of the first indication field may be 00, 01, 10, 11.

By different values of the first indication field, different BLERs may be indicated. Assuming that n reference BLERs are set, the number of values of the first indication field is greater than or equal to n. For example, 2 reference BLERs are set, the first indication field is 1 bit, and the number of values of the first indication field is 2, and then the 2 values may be respectively associated with the 2 reference BLERs. For another example, 3 reference BLERs are set, the first indication field is 2 bits, the number of values of the first indication field is 4, where 3 values are respectively associated with 3 reference BLERs, and another value may be set to indicate a default reference BLER, or multiplexed to indicate other information, etc.

In the case where the value of the first indication field is the ith value (or, in other words, the ith value in all the cases of the value of the first indication field), the terminal device determines the first feedback information based on the ith reference BLER corresponding to the ith value among the n reference BLERs. For example, if the value of the first indication field includes a first value and a second value, the terminal device may determine the first feedback information based on a first reference BLER of the n reference BLERs if the value of the first indication field is the first value; in case the value of the first indication field is the second value, the terminal device may determine the first feedback information based on the second reference BLER of the n reference BLERs.

Taking the i-th reference BLER determined by the terminal device as a value or a set including only one BLER as an example, the terminal device may use the i-th reference BLER corresponding to the i-th reference BLER in the n reference BLERs as a target BLER based on the i-th value of the first indication domain, and further determine the first feedback information based on the target BLER.

Taking the i-th reference BLER determined by the terminal device as a set including a plurality of BLERs as an example, the terminal device determines the i-th reference BLER corresponding to the i-th reference BLER in the n-th reference BLERs based on the i-th value of the first indication domain, and since the i-th reference BLER is a set including a plurality of BLERs, the terminal device may further select one BLER from the plurality of BLERs as a target BLER based on other information, or the terminal device may randomly select one BLER from the plurality of BLERs as a target BLER. For the procedure of selecting the target BLER by the terminal device based on other information, please refer to the following embodiments, which are not repeated here.

In yet another example, the first PDSCH related information includes: HARQ-ACK information corresponding to a first PDSCH; the step 310 includes: the terminal equipment determines first feedback information based on a first reference BLER in n reference BLER under the condition that HARQ-ACK information corresponding to a first PDSCH is ACK; and the terminal equipment determines the first feedback information based on the second reference BLER in the n reference BLER under the condition that the HARQ-ACK information corresponding to the first PDSCH is NACK (Negative Acknowledgement ).

For the received PDSCH, the terminal device needs to report HARQ-ACK information of the PDSCH to the network device. Since HARQ-ACK information of PDSCH may be ACK or NACK, different contents of HARQ-ACK information may be associated with different reference BLERs.

In the embodiment of the present application, in the case that HARQ-ACK information corresponding to the first PDSCH is ACK, the terminal device determines first feedback information based on a first reference BLER corresponding to ACK from among n reference BLERs; and under the condition that the HARQ-ACK information corresponding to the first PDSCH is NACK, the terminal equipment determines first feedback information based on a second reference BLER corresponding to the NACK in the n reference BLER.

It should be appreciated that in the embodiment of the present application, the first reference BLER/second reference BLER may be a value or a set including only one BLER, so that the terminal device may directly take the first reference BLER/second reference BLER as the target BLER and determine the first feedback information further based on the target BLER. In this embodiment of the present application, the first BLER/second BLER may also be a set including a plurality of BLERs, so that the terminal device may further select one BLER from the plurality of BLERs as the target BLER based on other information, or the terminal device may randomly select one BLER from the plurality of BLERs as the target BLER. For the procedure of selecting the target BLER by the terminal device based on other information, please refer to the following embodiments, which are not repeated here.

Taking a serving cell with a subcarrier spacing of 60kHz as an example, even if there is a requirement of low delay of the URLLC service, two transmissions (primary transmission+retransmission) can be tolerated, and then a reasonable network device is implemented as follows: for primary transmission, the BLER of 1e-1 is used for improving spectral efficiency, and if primary transmission fails, the BLER of 1e-5 is used for scheduling retransmission to ensure the reliability of the data packet. Under the condition that the HARQ-ACK information is ACK, the fact that the data packet terminal equipment is received correctly at this time is indicated, and the network equipment schedules the initial transmission of the next data packet next time, so that BLER corresponding to the ACK can be 1e-1; and under the condition that the HARQ-ACK information is NACK, the network equipment schedules retransmission of the data packet next time if the data packet is incorrectly received by the data packet terminal equipment, and the BLER corresponding to the NACK can be 1e-5. By determining the target BLER based on the HARQ-ACK, the target BLER may be more matched with the BLER used by the network device for the next scheduling, so as to minimize complexity of an implementation algorithm of the MCS used by the network device for the next scheduling according to the reported first feedback information.

Based on this, the first reference BLER, on which the HARQ-ACK information is ACK, is greater than or equal to the second reference BLER, on which the HARQ-ACK information is NACK. For example, the HARQ-ACK information is ACK, and the terminal device takes 1e-1 (first reference BLER) as the target BLER; the HARQ-ACK information is NACK, and the terminal device takes 1e-5 (second reference BLER) as the target BLER. For another example, the HARQ-ACK information is ACK and the terminal device takes 1e-1 or {1e-1} (first reference BLER) as the target BLER; the HARQ-ACK information is NACK and the terminal device further determines the target BLER based on {1e-1,1e-5 }.

In yet another example, the first PDSCH related information includes: the first PDSCH is primary transmission or retransmission, and/or NDI corresponding to the first PDSCH is overturned or not overturned; the step 310 includes: the terminal equipment determines first feedback information based on a first reference BLER in n reference BLER under the condition that a first PDSCH is primary transmission and/or NDI corresponding to the first PDSCH is overturned; and the terminal equipment determines the first feedback information based on the second reference BLER in the n reference BLER under the condition that the first PDSCH is retransmitted and/or the NDI corresponding to the first PDSCH is not overturned.

The data carried in the first PDSCH may be primary transmission data or retransmission data, so that two different situations of primary transmission or retransmission of the first PDSCH may be associated with different reference BLERs. For the determination of the first PDSCH being the initial transmission or the retransmission, please refer to the above embodiment, and the description thereof is omitted here. It should be understood that in the case where the first PDSCH is a DCI scheduled PDSCH, the first PDSCH is a primary transmission or retransmission, and may also be referred to as NDI inversion or non-inversion corresponding to the first PDSCH, which should have the same meaning.

In the embodiment of the present application, when the first PDSCH is primary transmission and/or when the NDI corresponding to the first PDSCH is flipped, the terminal device determines the first feedback information based on a first reference BLER among the n reference BLERs; and under the condition that the first PDSCH is retransmitted and/or the NDI corresponding to the first PDSCH is not overturned, the terminal equipment determines the first feedback information based on the second reference BLER in the n reference BLER.

For PDSCH, there may be multiple transmissions (primary transmission+retransmission), one implementation of the network device is: and (3) using the BLER scheduling of 1e-1 to initially transmit to improve the spectral efficiency, and if the initial transmission fails, using the BLER of 1e-5 to schedule retransmission to ensure the reliability of the data packet. By determining the target BLER based on the PDSCH being a primary or retransmission (or based on the NDI flip or not flip corresponding to the PDSCH), the target BLER may be matched as much as possible to the BLER used by the network device to schedule the PDSCH, reducing quantization overhead.

Based on the first reference BLER, which is based on the terminal equipment when the first PDSCH is the initial transmission and/or the NDI corresponding to the first PDSCH is overturned, is greater than or equal to the second BLER, which is based on the terminal equipment when the first PDSCH is the retransmission and/or the NDI corresponding to the first PDSCH is not overturned. For example, the first PDSCH is primary transmission, and/or NDI corresponding to the first PDSCH is flipped, and the terminal device takes 1e-1 (first reference BLER) as the target BLER; the first PDSCH is retransmitted and/or NDI corresponding to the first PDSCH is not flipped, and the terminal device uses 1e-5 (second reference BLER) as the target BLER. For another example, the first PDSCH is primary, and/or NDI corresponding to the first PDSCH is flipped, and the terminal device takes 1e-1 or {1e-1} (first reference BLER) as the target BLER; the first PDSCH is retransmitted and/or NDI corresponding to the first PDSCH is not flipped, and the terminal device further determines the target BLER based on {1e-1,1e-5 }.

In the above example, when the terminal device determines the target BLER based on n reference BLERs again, the terminal device needs to further select the target BLER from the plurality of BLERs, since the reference BLER may be a set including the plurality of BLERs. Based on this, the embodiment of the present application uses the terminal device as an example based on the HARQ-ACK information, and the first PDSCH is information such as initial transmission or retransmission, and describes how to select the target BLER from multiple BLERs.

In one example, the first PDSCH related information includes: HARQ-ACK information corresponding to a first PDSCH; the step 310 includes: the terminal equipment determines first feedback information based on a first BLER in a third reference BLER under the condition that HARQ-ACK information corresponding to a first PDSCH is ACK; and the terminal equipment determines the first feedback information based on the second BLER in the third reference BLER under the condition that the HARQ-ACK information corresponding to the first PDSCH is NACK.

The third reference BLER is a set including a plurality of BLERs, and may be the first reference BLER or the second reference BLER. For ease of description, in this example, a set including a plurality of BLERs is referred to as a third reference BLER. Different ones of the third reference BLERs are associated with different content of HARQ-ACK information.

Under the condition that the HARQ-ACK information corresponding to the first PDSCH is ACK, the terminal equipment determines first feedback information based on a first BLER in a third reference BLER; and under the condition that the HARQ-ACK information corresponding to the first PDSCH is NACK, the terminal equipment determines first feedback information based on the second BLER in the third reference BLER. In other words, the terminal device selects one BLER from the third reference BLER as a target BLER based on the content of HARQ-ACK information corresponding to the first PDSCH, and further determines the first feedback information based on the target BLER.

As can be seen from the above examples, when the HARQ-ACK information is ACK, the network device may use a larger BLER to improve the spectral efficiency; when the HARQ-ACK information is NACK, the network device may use a smaller BLER to ensure the reliability of the data packet. Based on this, the first BLER corresponding to the ACK is greater than the second BLER corresponding to the NACK. For example, when the HARQ-ACK information is ACK, the terminal device takes 1e-1 (first BLER) as the target BLER; and when the HARQ-ACK information is NACK, the terminal equipment takes 1e-5 (second BLER) as a target BLER.

In another example, the first PDSCH related information includes: the first PDSCH is primary transmission or retransmission, and/or NDI corresponding to the first PDSCH is overturned or not overturned; the step 310 includes: the terminal equipment determines first feedback information based on a first BLER in a third reference BLER under the condition that a first PDSCH is primary transmission and/or an NDI corresponding to the first PDSCH is overturned; and the terminal equipment determines the first feedback information based on the second BLER in the third reference BLER under the condition that the first PDSCH is retransmitted and/or the NDI corresponding to the first PDSCH is not overturned.

Under the condition that the first PDSCH is primary transmission and/or NDI (non-acknowledgement indicator) corresponding to the first PDSCH is overturned, the terminal equipment determines first feedback information based on a first BLER in a third reference BLER; and under the condition that the first PDSCH is retransmitted and/or the NDI corresponding to the first PDSCH is not overturned, the terminal equipment determines the first feedback information based on the second BLER in the third reference BLER. In other words, the terminal device selects one BLER from the third reference BLER as the target BLER based on the first PDSCH being a primary transmission or retransmission and/or the NDI corresponding to the first PDSCH being flipped or not flipped, and further determines the first feedback information based on the target BLER.

As can be seen from the above examples, the network device uses a larger BLER schedule to initially transmit to improve the spectral efficiency, and if the initial transmission fails, the network device uses a smaller BLER schedule to retransmit to ensure the reliability of the data packet. Based on the above, the first PDSCH is a first BLER corresponding to the initial transmission and/or NDI inversion corresponding to the first PDSCH, which is greater than a second BLER corresponding to the retransmission of the first PDSCH and/or NDI non-inversion corresponding to the first PDSCH. For example, when the first PDSCH is initial transmission and/or NDI corresponding to the first PDSCH is flipped, the terminal device takes 1e-1 (first BLER) as the target BLER; and when the first PDSCH is retransmitted and/or the NDI corresponding to the first PDSCH is not overturned, the terminal equipment takes 1e-5 (second BLER) as a target BLER.

In summary, according to the technical solution provided in the embodiment of the present application, the target BLER on which the feedback information of the channel state is based is determined by multiple information related to the PDSCH, such as the serving cell in which the PDSCH is located, HARQ-ACK information corresponding to the PDSCH, a priority index of an uplink channel carrying the HARQ-ACK information corresponding to the PDSCH, a first indication field in DCI for scheduling the PDSCH, the PDSCH being primary transmission or retransmission, NDI inversion or non-inversion corresponding to the PDSCH, factors affecting transmission efficiency, transmission reliability, and the like are fully considered, which is conducive to reducing quantization overhead, and is conducive to minimizing complexity of implementation algorithm of MCS used by network equipment for determining the scheduled data packet.

It should be noted that, in the embodiment of the present application, the terminal device may determine the target BLER based on the first feedback information by combining the above-mentioned multiple information related to the first PDSCH. In the following, a scheme for determining a target BLER in combination with various information related to the first PDSCH is described as an example.

In one example, the network device configures the terminal device with two serving cells, serving cell 1 and serving cell 2, respectively. Wherein, the subcarrier interval of the BWP activated by the serving cell 1 is 15kHz, and the subcarrier interval of the BWP activated by the serving cell 2 is 60kHz.

Assume that the serving cell 1 is provided with two reference BLERs, namely 1e-1 and 1e-5, wherein the priority index of the uplink channel corresponding to 1e-1 is priority index 0, and the priority index of the uplink channel corresponding to 1e-5 is priority index 1.

Assume that the serving cell 2 is provided with two reference BLERs, namely {1e-1} and {1e-1,1e-5}, the priority index of the uplink channel corresponding to {1e-1} is priority index 0, and the priority index of the uplink channel corresponding to {1e-1,1e-5} is priority index 1.

Taking a serving cell where the first PDSCH is located as an example of a serving cell 1, the terminal device determines that the target BLER is 1e-1 when the priority index of an uplink channel carrying HARQ-ACK information corresponding to the first PDSCH is priority index 0; and when the priority index of the uplink channel carrying the HARQ-ACK information corresponding to the first PDSCH is priority index 1, the terminal equipment determines that the target BLER is 1e-5.

Taking a serving cell where the first PDSCH is located as an example of a serving cell 2, the terminal device determines that the target BLER is 1e-1 when the priority index of the uplink channel carrying HARQ-ACK information corresponding to the first PDSCH is priority index 0; and when the priority index of the uplink channel carrying the HARQ-ACK information corresponding to the first PDSCH is priority index 1, the terminal equipment further determines the target BLER based on {1e-1,1e-5 }. At this time, the terminal device may determine the target BLER in any one of the following ways.

(1) The terminal device determines a target BLER based on HARQ-ACK information corresponding to the first PDSCH. The terminal equipment takes 1e-1 in {1e-1,1e-5} as a target BLER under the condition that HARQ-ACK information corresponding to the first PDSCH is ACK; and the terminal equipment takes 1e-5 in {1e-1,1e-5} as a target BLER under the condition that the HARQ-ACK information corresponding to the first PDSCH is NACK.

(2) The terminal device determines the target BLER based on whether the first PDSCH is an initial transmission or a retransmission and/or whether the NDI corresponding to the first PDSCH is flipped or not flipped. Under the condition that the first PDSCH is primary transmission and/or the NDI corresponding to the first PDSCH is overturned, the terminal equipment takes 1e-1 in {1e-1,1e-5} as a target BLER; and the terminal equipment takes 1e-5 in {1e-1,1e-5} as a target BLER under the condition that the first PDSCH is retransmitted and/or NDI corresponding to the first PDSCH is not overturned.

The manner in which the terminal device determines the first feedback information will be described below.

In one example, the method further comprises: the terminal equipment determines first feedback information based on the second difference value and the target reference difference value set.

The second difference is based on the target BLER and the second difference is a difference between the target MCS and the reference MCS. Wherein, the target MCS is an MCS obtained based on the target BLER, and the determining process of the target BLER is referred to the above embodiment, and is not repeated herein; the reference MCS corresponds to the first PDSCH or is configured by the network device or predefined by the communication protocol. Optionally, the MCS corresponding to the first PDSCH is an MCS included in DCI for scheduling the first PDSCH.

In the embodiment of the present application, the terminal device may determine the first feedback information based on the second difference and the target reference difference set. The set of target reference differences includes at least one reference difference including a second difference. Optionally, the reference difference in the target reference difference set may be a numerical value or a range of differences. For example, the target reference difference set is {. Ltoreq.2, -1,0,. Gtoreq.1 }.

Optionally, the reference difference value in the target reference difference value set is predefined by the communication protocol or configured by the network device with corresponding feedback information based on its corresponding position in the target reference difference value set, so that the terminal device may determine the corresponding position of the second difference value in the target reference difference value set, so as to further determine the first feedback information corresponding to the second difference value. Optionally, the network device configures feedback information corresponding to different positions in the target reference difference set for the terminal device through a high-layer signaling, where the high-layer signaling includes at least one of the following: SIB, RRC, MAC. Of course, the feedback information corresponding to the reference difference in the target reference difference set may also be determined in other manners, for example, defined by a communication protocol or configured with corresponding feedback information by the network device based on the size of the reference difference, and it should be understood that these determination manners are all within the protection scope of the present application.

Illustratively, for a target set of reference differences {. Ltoreq.2, -1,0,. Gtoreq.1 }, where a reference difference of +.ltoreq.2 corresponds to a first feedback information of 00, a reference difference of-1 corresponds to a first feedback information of 01, a reference difference of 0 corresponds to a first feedback information of 10, and a reference difference of ∈1 corresponds to a first feedback information of 11.

It should be understood that the second difference and the first difference in the embodiments of the present application are the same in the meaning of expression, and are used to represent the difference between the target MCS and the reference MCS; however, the second difference and the first difference may be different in expression form, for example, the target MCS is 4, the reference MCS is 3, the second difference may be 4-3=1, further, based on the reference difference corresponding to the second difference in the target reference difference set, the first difference is determined to be 11, and the first feedback information including the first difference is determined to be 11.

In another example, the method further comprises: the terminal equipment determines first feedback information based on the first value and the target reference difference value set; the first value is obtained by the terminal device based on the second difference value and the target offset value.

In this example, after determining the second difference, the terminal device determines a first value based on the second difference and the target offset value, and further determines the first feedback information based on the first value and the target reference difference set. Optionally, the terminal device adds the target offset value, subtracts the target offset value, multiplies the target offset value, and the like on the basis of the second difference value, to obtain the first value. For the target reference difference set, other contents of the first feedback information are determined based on the first value and the target reference difference set, please refer to the above embodiment, and the description is omitted herein.

In the above embodiments, the terminal device may determine the target reference difference value set from the at least one reference difference value set, and determine the target offset value from the at least one offset value, with reference to the target reference difference value set and the target offset value. Optionally, at least one set of reference difference values is configured by the network device; alternatively, at least one set of reference difference values is predefined by the communication protocol. Optionally, the at least one offset value is configured by the network device; alternatively, at least one offset value is predefined by the communication protocol. The method for determining the target reference difference value set and the target offset value by the terminal equipment is not limited in the embodiment of the present application, and several determination methods are exemplarily shown below.

In one example, the terminal device determines the first feedback information based on a second indication field in the DCI. The DCI is used to schedule or activate the first PDSCH, and the second indication field in the DCI is used to determine the target reference difference set and/or the target offset value based on which the first feedback information is based, or the second indication field in the DCI is used to indicate the target reference difference set and/or the target offset value, as it were. Alternatively, the second indication field may be a newly defined indication field in DCI, or may be an indication field already defined in multiplexing DCI, which is not limited in the embodiment of the present application. Alternatively, the number of bits in the second indication field may be 1 bit, or may be multiple bits, such as 2 bits, 3 bits, or the like, which is not limited in the embodiment of the present application.

In combination with the above embodiment, in the case of determining the first feedback information based on the second difference value and the target reference difference value set, the terminal device determines the target reference difference value set from the at least one reference difference value set based on the second indication field in the DCI; in case the first value is derived based on the second difference value and the target offset value and the first feedback information is determined based on the first value and the target reference difference set, the terminal device determines the target offset value from the at least one offset value and/or the target reference difference set from the at least one reference difference set based on the second indication field in the DCI.

For example, when the value of the second indication field is the first value, the terminal device determines the first feedback information based on the first reference difference set in the at least one reference difference set (or the terminal device may determine the first reference difference set in the at least one reference difference set as the target reference difference set and determine the first feedback information based on the target reference difference set); alternatively, the terminal device determines the first feedback information based on the first offset value of the at least one offset value (or, the terminal device may determine the first offset value of the at least one offset value as a target offset value and determine the first feedback information based on the target offset value); alternatively, the terminal device does not determine the first feedback information based on the at least one offset value (or the terminal device determines the first feedback information directly based on the second difference value and the set of target reference difference values).

For example, when the value of the second indication field is the second value, the terminal device determines the first feedback information based on the second reference difference set in the at least one reference difference set (or the terminal device may determine the second reference difference set in the at least one reference difference set as the target reference difference set and determine the first feedback information based on the target reference difference set); alternatively, the terminal device determines the first feedback information based on the second offset value of the at least one offset value (or, the terminal device may determine the second offset value of the at least one offset value as a target offset value and determine the first feedback information based on the target offset value).

For example, when the value of the second indication field is the third value, the terminal device determines the first feedback information based on the third reference difference set in the at least one reference difference set (or the terminal device may determine the third reference difference set in the at least one reference difference set as the target reference difference set and determine the first feedback information based on the target reference difference set); alternatively, the terminal device determines the first feedback information based on a third offset value of the at least one offset value (or, the terminal device may determine the third offset value of the at least one offset value as a target offset value and determine the first feedback information based on the target offset value).

In the case that the at least one reference difference set includes more than three reference difference sets and the at least one offset value includes more than three offset values, the description of how the terminal device determines the first feedback information based on the value of the second indication field may be obtained based on the above example, which is not repeated herein.

For example, the at least one set of reference differences is {. Ltoreq.2, -1,0,. Gtoreq.1 }, {. Ltoreq.1, 2,3,. Gtoreq.4 }, {. Ltoreq.5, -4, -3,. Gtoreq.2 }, respectively, and the at least one offset value is 0, +3, -3, or +3, -3, respectively. Assuming that the second indication field is 2 bits, the values of the second indication field may be 00, 01, 10, 11. When the second indication domain is 00, the terminal equipment determines { -2, -1,0, > 1} as a target reference difference value set, or determines 0 as a target offset value, or does not use at least one offset value to determine the first feedback information; when the second indication field is 01, the terminal equipment determines { less than or equal to 1,2,3, > 4} as a target reference difference value set, or determines +3 as a target offset value; when the second indication field is 10, the terminal equipment determines {. Ltoreq.5, -4, -3,. Gtoreq.2 } as a target reference difference value set, or determines-3 as a target offset value; when the second indication field is 11, the second indication field is default.

In another example, the terminal device determines the first feedback information based on the first rule. The first rule is used to determine a set of target reference difference values and/or a target offset value based on which the first feedback information is based.

In combination with the above embodiment, in the case of determining the first feedback information based on the second difference value and the target reference difference value set, the terminal device determines the target reference difference value set from the at least one reference difference value set based on the first rule; in case the first value is derived based on the second difference and the target offset value and the first feedback information is determined based on the first value and the target reference difference set, the terminal device determines the target offset value from the at least one offset value and/or the target reference difference set from the at least one reference difference set based on the first rule.

The embodiment of the application does not limit the specific content of the first rule, and optionally, the first rule may determine the target reference difference value set and/or the target offset value through information related to the first PDSCH. For description of the information related to the first PDSCH, please refer to the above embodiment, and the description is omitted here.

For the case (1), the BLER used by the network device to schedule the data packet is the same as the target BLER (e.g. 1e-1 or 1 e-5), at this time, the terminal device determines the first feedback information based on the first reference difference set in the at least one reference difference set (or, the terminal device may determine the first reference difference set in the at least one reference difference set as the target reference difference set, and determine the first feedback information based on the target reference difference set); alternatively, the terminal device determines the first feedback information based on the first offset value of the at least one offset value (or, the terminal device may determine the first offset value of the at least one offset value as a target offset value and determine the first feedback information based on the target offset value); alternatively, the terminal device does not determine the first feedback information based on the at least one offset value (or the terminal device determines the first feedback information directly based on the second difference value and the set of target reference difference values).

For the case (2), the BLER used by the network device to schedule the data packet is greater than the target BLER (e.g., the BLER used by the network device to schedule the data packet is 1e-1, and the target BLER is 1 e-5), where the terminal device determines the first feedback information based on the second set of reference differences in the at least one set of reference differences (or the terminal device may determine the second set of reference differences in the at least one set of reference differences as the target set of reference differences and determine the first feedback information based on the target set of reference differences); alternatively, the terminal device determines the first feedback information based on the second offset value of the at least one offset value (or, the terminal device may determine the second offset value of the at least one offset value as a target offset value and determine the first feedback information based on the target offset value).

For the case (3), the BLER used by the network device to schedule the data packet is less than the target BLER (e.g., the BLER used by the network device to schedule the data packet is 1e-5, and the target BLER is 1 e-1), at which time, the terminal device determines the first feedback information based on the third set of reference differences in the at least one set of reference differences (or the terminal device may determine the third set of reference differences in the at least one set of reference differences as the target set of reference differences and determine the first feedback information based on the target set of reference differences); alternatively, the terminal device determines the first feedback information based on a third offset value of the at least one offset value (or, the terminal device may determine the third offset value of the at least one offset value as a target offset value and determine the first feedback information based on the target offset value).
