Description

1 / 45 METHOD FOR DETERMINING THE LOCATION OF A RESOURCE IMPLEMENTED BY A TERMINAL DEVICE, TERMINAL DEVICE IN A COMMUNICATION SYSTEM, AND COMPUTER STORAGE MEDIA BACKGROUND FIELD OF TECHNIQUE

[001] The present invention relates to the field of information processing technologies, and in particular to a method for determining the location of a resource, a terminal device, a network device, and a computer storage medium. RELATED TECHNIQUE

[002] Different numerologies are introduced to NR. For different numerologies, the subcarrier spacings in a frequency domain are different, and the time lengths of all slots in a time domain are also different. When different numerologies are used for an uplink and a downlink, the slot count of the uplink and the downlink is different. For channel state information (CSI) reporting, the reference needs to be made based on a CSI reference feature, and a location of the CSI reference feature depends on a reporting moment and nCQI_ref (i.e., a slot offset of the CSI reference feature relative to the reporting moment).

[003] Currently, the standards only provide nCQI_ref values ​​under different numerologies, and it is not given whether the numerology is determined based on an ascending linkage report numerology or a descending linkage measurement numerology. Furthermore, when different Petition 870200132292, dated 10 / 20 / 2020, page 7 / 134 2 / 45 numerologies are used for an ascending link and a descending link; a plurality of descending link subframes can be obtained according to a reporting moment and nCQI_ref. How to determine which descending link subframe is the CSI reference feature is also a problem to be solved. SUMMARY

[0023] To make the features and technical content of the embodiments of the present invention more comprehensive, implementations of the embodiments of the present invention are described below in detail with reference to the accompanying drawings. The accompanying drawings are for reference only and are not intended to limit the embodiments of the present invention. EMBODIMENT 1

[0024] This embodiment of the present invention provides a method for determining a resource location, wherein the method is applied to a terminal device and, as shown in Figure 1, includes:

[0025] Step 101: Determine a slot offset based on the downlink measurement resource configuration and the uplink reporting resource configuration that are included in the CSI reporting configuration information, where the slot offset represents a slot offset CSI reference resource relative to a reporting moment.

[0026] Step 102: Determine a location for Petition 870200132292, dated 10 / 20 / 2020, page 11 / 134 6 / 45 CSI reference feature in a time domain based at least on slot offset.

[0027] Before step 101 is performed, the method additionally includes:

[0028] receive initial information sent by one side of the network; and obtain at least one CSI report configuration information based on the initial information.

[0029] Specifically, CSI report configuration information additionally includes: the CSI report that is at least one of the following: periodic report, quasi-periodic report, and aperiodic report.

[0030] The downlink measurement resource configuration included in the CSI report configuration information includes: a configuration for a measurement resource that corresponds to a CSI report.

[0031] The uplink reporting resource configuration included in the CSI reporting configuration information includes: PUCCH resource configuration during reporting and / or PUSCH resource configuration during reporting.

[0032] It should be noted that the PUCCH resource setting may be a subcarrier spacing when the report is performed using a PUCCH; and the PUSCH resource setting may be a subcarrier spacing when the report is performed using a PUSCH. Certainly, the PUCCH or PUSCH resource setting may additionally include other parameters, however, the parameters are not exhaustively listed in this mode.

[0033] In step 101 above, the determination of Petition 870200132292, dated 10 / 20 / 2020, page 12 / 134 7 / 45 A slot shift based on the downlink measurement feature configuration and the uplink reporting feature configuration, which are included in the CSI reporting configuration information, may include the following various specific processing methods.

[0034] Mode 1: When the CSI report is a periodic or quasi-periodic report, the slot offset of the CSI reference feature relative to the reporting time is determined based on the feature configuration during the PUCCH or PUSCH report.

[0035] Specifically, during periodic reporting or quasi-periodic reporting, an nCQI_ref value (the slot offset of the CSI reference feature relative to the reporting time) is obtained by querying the table using a subcarrier spacing in the feature configuration during PUCCH or PUSCH reporting.

[0036] A table, which corresponds to the table lookup operation, can be a first table that corresponds to a predefined subcarrier spacing and a predefined slot offset.

[0037] It should be noted that, for the method of determining, based on a resource configuration during PUCCH or PUSCH reporting, the slot offset of the CSI reference resource relative to the reporting time, in addition to the table query described above, other processing methods may also exist. For example, the slot offset can be determined using a predefined match. For example, it is predefined that a subcarrier spacing of 1 that corresponds to PUCCH or PUSCH corresponds to a slot offset of 1, and a spacing Petition 870200132292, dated 10 / 20 / 2020, page 13 / 134 8 / 45 of subcarrier 2 corresponds to a slot offset of 2. Alternatively, the calculation can be performed based on a predefined calculation formula. For example, a calculation formula is specified according to a correspondence between a subcarrier spacing and a slot offset, and the slot offset can be obtained by performing the calculation on different subcarrier spacings and corresponding parameters, where the specified calculation formula can be tailored to a real-world case.

[0038] Mode 2: When the CSI report is a periodic or quasi-periodic report, the slot offset of the CSI reference resource relative to the reporting time is determined based on the resource configuration of a downlink measurement resource that matches the CSI report configuration information.

[0039] Specifically, during the periodic report or quasi-periodic report, an nCQI_ref value is obtained by querying the table using a subcarrier spacing of the downlink measurement resource that corresponds to the CSI report.

[0040] In other words, in this way, the downlink measurement resource configuration may additionally include: subcarrier spacing.

[0041] Similarly, a processing method for the table query in this mode can also be overridden. The specific override processing is the same as in Mode 1, and the details are not described. Petition 870200132292, dated 10 / 20 / 2020, page 14 / 134 9 / 45 in this document again.

[0042] Mode 3: When the CSI report is a periodic or quasi-periodic report, the slot offset of the CSI reference resource relative to the reporting time is determined based on the resource configuration during the PUCCH or PUSCH report and the resource configuration during the downlink measurement that corresponds to the CSI report configuration information.

[0043] Specifically, when the CSI report is a periodic or quasi-periodic report, the slot offset of the CSI reference resource relative to the reporting time is obtained based on a smaller or larger subcarrier spacing in the resource configuration during PUCCH or PUSCH reporting and in the resource configuration during downlink measurement that corresponds to the CSI reporting configuration information.

[0044] For example, an nCQI_ref value can be obtained through table querying using the smaller or larger subcarrier spacing of the downlink measurement feature that corresponds to the CSI report during PUCCH or PUSCH reporting. Similarly, a processing method for the table query in this way can also be substituted. The specific substitution processing is the same as Mode 1, and the details are not described herein again.

[0045] Mode 4: When the CSI report is an aperiodic report, the slot offset of the CSI reference feature relative to the reporting time is obtained according to a CSI calculation time. Petition 870200132292, dated 10 / 20 / 2020, page 15 / 134 10 / 45

[0046] For example, if the report is performed using a PUSCH (or a PUCCH), when aperiodic CSIs are reported using the PUSCH, an nCQI_ref value is obtained using Z' (i.e., a calculation time of the CSIs for the aperiodic CSI report).

[0047] Z' can be represented by a number of symbols required by a terminal of a last symbol of a CSI-RS or CSI-IM whose time domain start position is later and which is used to measure the CSI for the PUSCH report.

[0048] Mode 5: When the network side is notified, using a terminal reporting capability, of a slot offset value that can be supported by the terminal device, the slot offset of the CSI reference resource relative to the time of reporting is determined based on one of the following processing methods:

[0049] when the CSI report is a periodic report or a quasi-periodic report, obtain, using a subcarrier spacing during the PUCCH or PUSCH report, the slot offset of the CSI reference feature relative to the reporting time;

[0050] when the CSI report is a periodic report or a quasi-periodic report, obtain, using a subcarrier spacing of a downlink measurement resource that corresponds to the CSI report configuration information, the slot offset of the CSI reference resource relative to the reporting time; and

[0051] when the CSI report is a periodic report or a quasi-periodic report, obtain, based on Petition 870200132292, dated 10 / 20 / 2020, page 16 / 134 11 / 45 a smaller resource configuration subcarrier spacing during PUCCH or PUSCH reporting and in the resource configuration during downlink measurement that correspond to the CSI reporting configuration information, the CSI reference resource slot offset relative to the reporting time.

[0052] Specifically, a base station can be notified, using a terminal reporting capability, of an nCQI_ref value that can be supported by a user. A terminal obtains the nCQI_ref value through table querying according to any of the previous Mode 1, Mode 2, and Mode 3.

[0053] Similarly, a processing method for the table query in this method can also be overridden. The specific override processing is the same as in Mode 1, and the details are not described again in this document.

[0054] Based on the descriptions of the previous solutions, for determining a CSI reference resource location in a time domain based at least on the slot offset in step 102, i.e., determining, by a terminal, the location of the CSI reference resource in the time domain according to slot n (first uplink slot) and nCQI_ref at PUCCH reporting time or at PUSCH reporting time, a plurality of processing situations can also be included as follows.

[0055] Situation 1: The slot offset is subtracted from the first uplink slot at PUCCH reporting time or at PUSCH reporting time to obtain a second uplink slot, and use Petition 870200132292, dated 10 / 20 / 2020, page 17 / 134 12 / 45 is a first downlink slot that corresponds to the second uplink slot as the location of the CSI reference resource in the time domain.

[0056] Specifically, when slot offset is obtained by performing processing in the previous Mode 1, a slot in which nCQI_ref before slot n (first uplink slot) is located, i.e., n-nCQI_ref, is first obtained, and then a downlink slot that corresponds to the uplink slot is obtained.

[0057] Additionally, a first descending link slot is selected as the location of the CSI reference resource in the time domain when there are at least two first descending link slots that correspond to the first ascending link slot. In other words, a more anterior slot is selected as the time domain location of the CSI reference resource when there is a plurality of first descending link slots that correspond to the ascending link slot.

[0058] Alternatively, a first valid descending link slot is selected as the location of the CSI reference resource in the time domain when there are at least two first descending link slots that correspond to the first ascending link slot. In other words, a first valid descending link slot is selected as the time domain location of the CSI reference resource when there is a plurality of such first descending link slots that correspond to the ascending link slot.

[0059] Additionally, a first, most recent downlink slot is selected as the location of Petition 870200132292, dated 10 / 20 / 2020, page 18 / 134 13 / 45 CSI reference resource in the time domain when there are at least two downlink slots that correspond to the first uplink slot.

[0060] In other words, a more recent slot is selected as the time domain location of the CSI reference resource when there exists a plurality of such first downlink slots that correspond to the first uplink slot.

[0061] Alternatively, a more recent valid first downlink slot is selected as the location of the CSI reference resource in the time domain when there are at least two first downlink slots that match the first uplink slot.

[0062] In other words, a more recent valid downlink slot is selected as the timedomain location of the CSI reference resource when there exists a plurality of such first downlink slots that correspond to the first uplink slot.

[0063] Alternatively, the location of the CSI reference resource in the time domain is determined based on the first uplink slot and slot offset when there are at least two first downlink slots that correspond to the first uplink slot.

[0064] In other words, when there is a plurality of such first descending link slots that correspond to the first ascending link slot, a calculation formula, the first ascending link slot and the Petition 870200132292, dated 10 / 20 / 2020, page 19 / 134 14 / 45 slot offsets can be preset to calculate and obtain the location of the CSI reference feature in the time domain.

[0065] Alternatively, when there are at least two first downlink slots that correspond to the first uplink slot, a corresponding downlink slot is selected as a location for a CSI reference resource of at least two BWP bandwidth parts in the time domain based on at least one of the following ways:

[0066] select a first earliest descending link slot as the location of the CSI reference resource in the time domain;

[0067] select a first valid earliest descending link slot as the location of the CSI reference resource in the time domain;

[0068] select a first most recent downlink slot as the location of the CSI reference resource in the time domain; and

[0069] select the most recent valid first downlink slot as the location of the CSI reference resource in the time domain.

[0070] In other words, when there is a plurality of downlink slots that correspond to the uplink slot, a corresponding downlink slot is selected as the time-domain location of the CSI reference resource respectively according to the four ways described above. It should be noted that at least one of the four ways described above can be used. Petition 870200132292, dated 10 / 20 / 2020, page 20 / 134 15 / 45

[0071] Situation 2: A second downlink slot that corresponds to a first uplink slot at PUCCH reporting time or at PUSCH reporting time is determined; and the slot offset is subtracted from the second downlink slot, wherein a third downlink slot obtained is the location of the CSI reference resource in the time domain.

[0072] In other words, when slot offset is obtained in the previous Mode 2, a downlink slot n' (second downlink slot) that corresponds to slot n (first uplink slot) is first obtained, and a slot, in which nCQI_ref before the downlink slot n' (second downlink slot) is located, i.e., n'-nCQI_ref, is selected as the time domain location of the CSI reference feature.

[0073] Additionally, a second priority downlink slot is selected for calculation of the third downlink slot when there are at least two second downlink slots that correspond to the first uplink slot.

[0074] In other words, a priority downlink slot n' is selected for CSI reference resource calculation when there is a plurality of downlink slots n' (second downlink slots) that corresponds to uplink slot n (first uplink slot).

[0075] Alternatively, a last second priority downlink slot is selected for calculation. Petition 870200132292, dated 10 / 20 / 2020, page 21 / 134 16 / 45 of the third downlink slot when there are at least two second downlink slots that correspond to the first uplink slot.

[0076] In other words, a final downlink slot n' is selected for calculation of the third downlink slot to determine the CSI reference resource when there is a plurality of downlink slots n' (second downlink slots) that corresponds to the uplink slot n (first uplink slot).

[0077] Alternatively, the location of the CSI reference resource in the time domain is determined based on the first uplink slot and slot offset when there are at least two second downlink slots that correspond to the first uplink slot. In other words, a predefined calculation formula can be used to perform calculation when there is a plurality of second downlink slots that correspond to the first uplink slot.

[0078] Situation 3: A subcarrier spacing that corresponds to the slot offset is determined to be a downlink subcarrier spacing or an uplink subcarrier spacing, and, if the subcarrier spacing is a downlink subcarrier spacing, the location of the CSI reference feature in the time domain is calculated based on one of the following methods:

[0079] determine the location of the CSI reference resource in the time domain based on the first uplink slot and slot offset; Petition 870200132292, dated 10 / 20 / 2020, page 22 / 134 17 / 45

[0080] select a first earliest descending link slot as the location of the CSI reference resource in the time domain;

[0081] select a first valid earliest descending link slot as the location of the CSI reference resource in the time domain;

[0082] select a first most recent downlink slot as the location of the CSI reference resource in the time domain; and

[0083] select the most recent valid first downlink slot as the location of the CSI reference resource in the time domain.

[0084] In other words, when the slot offset is obtained through calculation based on the previous Mode 3, a subcarrier spacing, which corresponds to nCQI_ref, is first determined to be a downlink subcarrier spacing or an uplink subcarrier spacing, and, if the subcarrier spacing is a downlink subcarrier spacing, the time-domain location of the CSI reference feature is calculated according to at least one of several methods described above.

[0085] Furthermore, the subcarrier spacing that corresponds to the slot offset is determined to be either a descending link subcarrier spacing or an ascending link subcarrier spacing, and, if the subcarrier spacing is an ascending link subcarrier spacing, the earliest descending link slot is selected as the location of the CSI reference feature in the time domain. In other words, if Petition 870200132292, dated 10 / 20 / 2020, page 23 / 134 18 / 45 the subcarrier spacing that corresponds to the slot offset for an uplink subcarrier spacing, the time-domain location of the CSI reference resource is calculated according to the method where the first earliest downlink slot is selected as the location of the CSI reference resource in the time domain.

[0086] Finally, after step 102 is completed, the CSIs are calculated according to a given time domain location of the CSI reference resource, and the report is performed using a PUCCH or PUSCH resource.

[0087] It can be learned that, in the solution described above, a slot offset value of a CSI reference resource relative to a reporting moment can be obtained using a downlink measurement resource configuration and an uplink reporting resource configuration that are included in the CSI reporting configuration information, and, additionally, a location of the CSI reference resource in a time domain is determined based on the slot offset. In this way, the accuracy of the calculation for CSI is guaranteed and the processing efficiency of the system is improved. MODE 2

[0088] This embodiment of the present invention provides a method for determining a resource location, wherein the method is applied to a network device and includes: sending at least one initial piece of information to a terminal device, wherein the initial information carries at least CSI report configuration information, and the report configuration information Petition 870200132292, dated 10 / 20 / 2020, page 24 / 134 CSI 19 / 45 configurations include at least one downlink measurement feature setting and one uplink reporting feature setting.

[0089] Specifically, CSI report configuration information additionally includes: CSI reporting that is at least one of the following: periodic reporting, quasi-periodic reporting, and aperiodic reporting.

[0090] The downlink measurement resource configuration included in the CSI report configuration information includes: a configuration for a measurement resource that corresponds to a CSI report.

[0091] The uplink reporting resource configuration included in the CSI reporting configuration information includes: PUCCH resource configuration during reporting and / or PUSCH resource configuration during reporting.

[0092] It should be noted that the PUCCH resource setting may be a subcarrier spacing when the report is performed using a PUCCH; and the PUSCH resource setting may be a subcarrier spacing when the report is performed using a PUSCH. Certainly, the PUCCH or PUSCH resource setting may additionally include other parameters, however, the parameters are not exhaustively listed in this mode.

[0093] Correspondingly, on one end device side, a slot offset can be determined based on the downlink measurement feature configuration and the uplink reporting feature configuration that are included in the CSI reporting configuration information, and additionally, a Petition 870200132292, dated 10 / 20 / 2020, page 25 / 134 20 / 45 The location of a CSI reference resource in a time domain is determined based on at least the slot offset. That is, a terminal determines the location of the CSI reference resource in the time domain according to slot n (first uplink slot) and nCQI_ref at PUCCH reporting time or PUSCH reporting time, calculates the CSI according to a given time domain location of the CSI reference resource, and performs the report using a PUCCH or PUSCH resource.

[0094] It can be learned that, in the solution described above, the terminal device can be enabled to obtain a slot offset value of a CSI reference resource relative to a reporting moment using a downlink measurement resource configuration and an uplink reporting resource configuration that are included in the CSI reporting configuration information, and additionally determine a location of the CSI reference resource in a time domain based on the slot offset. In this way, the accuracy of the calculation for CSI is guaranteed and the processing efficiency of the system is improved. MODE 3

[0095] Based on the previous modalities, this modality additionally provides descriptions of a specific processing situation with reference to Table 1. When different numerologies exist, and the CSI report includes / does not include CRI, a slot is used as a unit of an nCQI_ref value (slot offset).

[0096] When an uplink subcarrier spacing is 15 kHz, and a spacing of Petition 870200132292, dated 10 / 20 / 2020, p. 26 / 134 If the downlink subcarrier spacing is 60 kHz, the nCQI_ref (slot offset) value can be determined based on Mode 1 in Mode 1. That is, the nCQI_ref (slot offset) value is determined to be 4 or 5 based on the uplink subcarrier spacing of 15 kHz. TABLE 1 nCQI ref (Slots) 15 KHz 3 0 KHZ 60 KHZ 120 KHz No CRI 4 8 16 32 CRI 5 10 20 40 MODE 4

[0097] Based on the previous modes, this mode additionally provides descriptions of a specific processing situation with reference to Table 2. When the CSI report includes / does not include CRI, ms is used as a unit of an nCQI_ref value (slot offset).

[0098] When CSI report does not include CRI, an uplink subcarrier spacing is 15 kHz, and a downlink subcarrier spacing is 60 kHz, in this case, the nCQI_ref (slot offset) value can be determined based on Mode 1 in Modality 1. A slot offset that does not include CRI is first obtained to be 4 ms, then according to 1 ms, which includes 4 slots, nCQI_ref is obtained to be 4 slots, where 1 ms, which includes 4 slots, is obtained based on the uplink subcarrier spacing. TABLE 2 nCQI_ref (ms) No CRI 4 CRI 5 MODE 5 Petition 870200132292, dated 10 / 20 / 2020, p. 27 / 134 22 / 45

[0099] Based on the previous modes, this mode additionally provides descriptions of a specific processing situation with reference to Table 3. When the CSI report includes / does not include CRI, ms is used as a unit of an nCQI_ref value (slot offset).

[00100] When the CSI report does not include CRI, an uplink subcarrier spacing is 30 kHz, and a downlink subcarrier spacing is 60 kHz, in this case, the nCQI_ref (slot offset) value can be determined based on Mode 1 in Modality 1. A slot offset that does not include CRI is first obtained to be 4 ms, then, based on 1 ms, which includes 4 slots, nCQI_ref is obtained to be 16 slots, where 1 ms, which includes 4 slots, is obtained based on the downlink subcarrier spacing. TABLE 3 nCQI_ref (ms) No CRI 4 CRI 5 MODE 6

[00101] The description is made with reference to Table 4. An uplink subcarrier spacing is 15 kHz, a downlink subcarrier spacing is 60 kHz, and it is assumed that a CSI slot for uplink reporting is a slot 5.

[00102] nCQI_ref (slot offset) is obtained based on the uplink subcarrier spacing, and its value is defined as 4. In this case, according to Situation 1 in the previous embodiment, 4 is subtracted from 5 to obtain 1, and 1 is used as a second link slot. Petition 870200132292, dated 10 / 20 / 2020, p. 28 / 134 23 / 45 ascending corresponding, is an ascending link slot 1.

[00103] In Table 4, the first downlink slots that correspond to uplink slot 1 are slots 1, 2, 3, and 4. In this case, according to the principle that a first downlink slot is selected as a location of a CSI reference resource in a time domain when there are at least two first downlink slots that correspond to the first uplink slot, slot 1 is selected as a slot in which a downlink CSI reference resource is located. TABLE 4 Slot Downlink 60 KHz 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Uplink 15 KHz 1 2 3 4 5

[00104] It should be noted that, in this embodiment, although processing is performed using an earlier first descending link slot as the location of the CSI reference feature in the time domain as a principle, in actual processing, a processing principle in which an earlier valid first descending link slot, a more recent first descending link slot, or a more recent valid first descending link slot is selected as the location of the CSI reference feature in the time domain may alternatively be used. Petition 870200132292, dated 10 / 20 / 2020, page 29 / 134 24 / 45

[00105] For example, with reference to the previous table, a first most recent descending link slot is selected, then slot 4 can be selected. Furthermore, assuming that slot 1 is invalid, slot 2 is valid, slot 3 is valid and slot 4 is invalid, if a first most recent descending link slot is selected, a slot that is finally selected can be slot 2; and if a first most recent valid descending link slot is selected, a slot that is finally selected can be slot 3. MODE 7

[00106] The description is made with reference to Table 5. It is assumed that an uplink subcarrier spacing is 15 kHz, a downlink subcarrier spacing is 60 kHz, and a CSI slot for uplink reporting is slot 5.

[00107] The nCQI_ref (slot offset) is obtained based on the uplink subcarrier spacing. In this case, a slot, in which a CSI reference resource is located, can also be obtained according to the following calculation method where μ can be a μ value that corresponds to a subcarrier spacing of a metering resource or another resource related to a downlink metering, and μ2 can be a μ value that corresponds to a subcarrier spacing of a PUCCH or reported PUSCH resource. It should be additionally noted that the calculation formula can be rounded up or rounded down. Petition 870200132292, dated 10 / 20 / 2020, p. 30 / 134 25 / 45

[00108] In this case, the slot in which a CSI reference resource is located can be calculated to be 4. TABLE 5 60 KHz downlink slot 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 15 kHz uplink slot 1 2 3 4 5 Mode 8

[00109] With reference to Table 6, a downlink subcarrier spacing of 15 is assumed. KHz, an uplink subcarrier spacing is KHz, and a CSI slot for uplink reporting is slot 18.

[00110] The nCQI_ref (slot offset) is obtained based on the subcarrier spacing of a downlink measurement resource, and its value is defined as 4. In this case, a slot, in which a CSI reference resource is located, can also be obtained according to the following calculation method where μ is a μ Petition 870200132292, dated 10 / 20 / 2020, p. 31 / 134 26 / 45 is a value that corresponds to a subcarrier spacing of a measurement resource or another resource related to a downlink measurement, and μ2 is a μ value that corresponds to a subcarrier spacing of a PUCCH or reported PUSCH resource. It should be noted that the previous formula can be rounded up or rounded down.

[00111] In this case, the slot in which a CSI reference feature is located can be calculated to be 0 (1 when rounded up). TABLE 6 Slot 60 KHz uplink link 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 15 KHz downlink link 1 2 3 4 5 MODE 9

[00112] With reference to Table 7, an uplink subcarrier spacing is 15 KHz, a downlink subcarrier spacing is 60 KHz, and it is assumed that a CSI slot for uplink reporting is slot 5. Petition 870200132292, dated 10 / 20 / 2020, p. 32 / 134 27 / 45

[00113] The nCQI ref (slot offset) is obtained based on the subcarrier spacing of a downlink measurement resource, and a value of the same is defined as 16. In this case, a slot, in which a CSI reference resource is located, can be obtained according to the following calculation method, where μ1 is a value that corresponds to a subcarrier spacing of a measurement resource or another resource related to a downlink measurement, and μ2 is a value that corresponds to a subcarrier spacing of a PUCCH or reported PUSCH resource. Similarly, the previous formula can be rounded up or rounded down.

[00114] In this case, the slot in which a CSI reference feature is located can be calculated to be 4 (also 4 when rounded up). TABLE 7 60 KHz Downstream Link Slot 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Petition 870200132292, dated 10 / 20 / 2020, page 33 / 134 28 / 45 Enl ace asc end ent of 15 KHz 1 2 3 4 5 MODE 10

[00115] In this embodiment of the present invention, a terminal device is provided, as shown in Figure 2, which includes:

[00116] a first processing unit 21 configured to determine a slot offset based on the downlink measurement resource configuration and the uplink reporting resource configuration that are included in the CSI reporting configuration information, wherein the slot offset represents a slot offset of a CSI reference resource relative to a reporting moment; and to determine a location of the CSI reference resource in a time domain based at least on the slot offset.

[00117] The terminal device additionally includes:

[00118] a first communications unit 22 configured to receive initial information sent by one side of the network.

[00119] Correspondingly, the first processing unit 21 is configured to obtain at least one CSI report configuration information based on the first information. Petition 870200132292, dated 10 / 20 / 2020, page 34 / 134 29 / 45

[00120] Specifically, CSI report configuration information additionally includes: CSI reporting that is at least one of the following: periodic report, quasi-periodic report, and aperiodic report.

[00121] The downlink measurement resource configuration included in the CSI report configuration information includes: a configuration for a measurement resource that corresponds to a CSI report.

[00122] The uplink reporting resource configuration included in the CSI reporting configuration information includes: PUCCH resource configuration during reporting and / or PUSCH resource configuration during reporting.

[00123] It should be noted that the PUCCH resource setting may be a subcarrier spacing when the report is performed using a PUCCH; and the PUSCH resource setting may be a subcarrier spacing when the report is performed using a PUSCH. Certainly, the PUCCH or PUSCH resource setting may additionally include other parameters, however, the parameters are not exhaustively listed in this mode.

[00124] Determining a slot offset based on the downlink measurement resource configuration and the uplink reporting resource configuration, which are included in the CSI reporting configuration information, may involve the following various specific processing methods.

[00125] Mode 1: The first processing unit 21 is configured for: when the CSI report is a periodic report or a quasi-periodic report, Petition 870200132292, dated 10 / 20 / 2020, page 35 / 134 30 / 45 determine, based on the resource configuration during the PUCCH or PUSCH report, the slot offset of the CSI reference resource relative to the reporting time.

[00126] Specifically, during periodic reporting or quasi-periodic reporting, an nCQI_ref value (the slot offset of the CSI reference feature relative to the reporting time) is obtained by querying the table using a subcarrier spacing in the feature configuration during PUCCH or PUSCH reporting.

[00127] A table, which corresponds to the table lookup operation, can be a first table that corresponds to a predefined subcarrier spacing and a predefined slot offset.

[00128] It should be noted that, for the method of determining, based on a resource configuration during PUCCH or PUSCH reporting, the slot offset of the CSI reference resource relative to the reporting time, in addition to the table query described above, other processing methods may also exist. For example, the slot offset can be determined using a predefined match. For example, it is predefined that a subcarrier spacing of 1 that corresponds to PUCCH or PUSCH corresponds to a slot offset of 1, and a subcarrier spacing of 2 corresponds to a slot offset of 2. Furthermore, the calculation can alternatively be performed based on a predefined calculation formula. For example, a calculation formula is specified according to a match between a subcarrier spacing and a slot offset, and the slot offset can be obtained by performing the calculation on different spacings of Petition 870200132292, dated 10 / 20 / 2020, page 36 / 134 31 / 45 subcarrier and corresponding parameters, where the specified calculation formula can be specified according to a real case.

[00129] Mode 2: The first processing unit 21 is configured to: when the CSI report is a periodic report or a quasi-periodic report, determine, based on the resource configuration of a downlink measurement resource that matches the CSI report configuration information, the slot offset of the CSI reference resource relative to the reporting time.

[00130] Specifically, during the periodic report or quasi-periodic report, an nCQI_ref value is obtained through table query using a subcarrier spacing of the downlink measurement resource that corresponds to the CSI report.

[00131] In other words, in this way, the downlink measurement resource configuration may additionally include: subcarrier spacing.

[00132] Similarly, a processing method for the table query in this method can also be substituted. The specific substitution processing is the same as in Mode 1, and the details are not described again in this document.

[00133] Mode 3: The first processing unit 21 is configured to: when the CSI report is a periodic or quasi-periodic report, determine, based on the resource configuration during the PUCCH or PUSCH report and the resource configuration during the downlink measurement, which corresponds to Petition 870200132292, dated 10 / 20 / 2020, page 37 / 134 32 / 45 CSI report configuration information, the slot offset of the CSI reference resource relative to the reporting time.

[00134] Specifically, when the CSI report is a periodic or quasi-periodic report, the slot offset of the CSI reference resource relative to the reporting time is obtained based on a smaller or larger subcarrier spacing in the resource configuration during PUCCH or PUSCH reporting and in the resource configuration during downlink measurement that corresponds to the CSI reporting configuration information.

[00135] For example, an nCQI_ref value can be obtained through table querying using the smaller or larger subcarrier spacing of the downlink measurement feature that corresponds to the CSI report during PUCCH or PUSCH reporting. Similarly, a processing method for the table query in this way can also be substituted. The specific substitution processing is the same as Mode 1, and the details are not described again in this document.

[00136] Mode 4: The first processing unit 21 is configured to: when the CSI report is an aperiodic report, obtain, according to a CSI calculation time, the slot offset of the CSI reference resource relative to the reporting time.

[00137] For example, if the report is performed using a PUSCH (or a PUCCH), when aperiodic CSIs are reported using the PUSCH, an nCQI_ref value is obtained using Z' (i.e., a calculation time of the CSIs for the aperiodic CSI report). Petition 870200132292, dated 10 / 20 / 2020, page 38 / 134 33 / 45

[00138] Z' can be represented by a number of symbols required by a terminal of a last symbol of a CSI-RS or CSI-IM whose time domain start position is later and which is used to measure the CSI for the PUSCH report.

[00139] Mode 5: The first processing unit 21 is configured to: when the network side is notified, using a terminal reporting capability, of a slot offset value that can be supported by the terminal device, determine the slot offset of the CSI reference resource relative to the time of reporting based on one of the following processing methods:

[00140] when the CSI report is a periodic report or a quasi-periodic report, obtain, using a subcarrier spacing during the PUCCH or PUSCH report, the slot offset of the CSI reference feature relative to the reporting time;

[00141] when the CSI report is a periodic report or a quasi-periodic report, obtain, using a subcarrier spacing of a downlink measurement resource that corresponds to the CSI report configuration information, the slot offset of the CSI reference resource relative to the reporting time; and

[00142] when the CSI report is a periodic report or a quasi-periodic report, obtain, based on a smaller resource configuration subcarrier spacing during the PUCCH or PUSCH report and the resource configuration during the downlink measurement that corresponds to the report configuration information of Petition 870200132292, dated 10 / 20 / 2020, page 39 / 134 34 / 45 CSI, the slot offset of the CSI reference resource relative to the reporting time.

[00143] Specifically, a base station can be notified, using a terminal reporting capability, of an nCQI_ref value that can be supported by a user. A terminal obtains the nCQI_ref value through table querying according to any of the previous Mode 1, Mode 2, and Mode 3.

[00144] Similarly, a processing method for the table query in this method can also be substituted. The specific substitution processing is the same as in Mode 1, and the details are not described again in this document.

[00145] Based on the descriptions of the previous solutions, for determining a CSI reference resource location in a time domain based at least on slot offset, i.e., determining, by a terminal, the location of the CSI reference resource in the time domain according to slot n (first uplink slot) and nCQI_ref at PUCCH reporting time or at PUSCH reporting time, a plurality of processing situations as follows can also be included.

[00146] Situation 1: The first processing unit 21 is configured to: subtract the slot offset from the first uplink slot at PUCCH reporting time or at PUSCH reporting time to obtain a second uplink slot, and use a first downlink slot that corresponds to the second uplink slot as the location of the CSI reference resource in the time domain. Petition 870200132292, dated 10 / 20 / 2020, page 40 / 134 35 / 45

[00147] Specifically, when slot offset is obtained by performing processing in the previous Mode 1, a slot in which nCQI_ref before slot n (first uplink slot) is located, i.e., n-nCQI_ref, is first obtained, and then a downlink slot that corresponds to the uplink slot is obtained.

[00148] Additionally, a first descending link slot is selected as the location of the CSI reference resource in the time domain when there are at least two first descending link slots that correspond to the first ascending link slot. In other words, a more anterior slot is selected as the time domain location of the CSI reference resource when there is a plurality of first descending link slots that correspond to the ascending link slot.

[00149] Alternatively, a first valid descending link slot is selected as the location of the CSI reference resource in the time domain when there are at least two first descending link slots that correspond to the first ascending link slot. In other words, a first valid descending link slot is selected as the time domain location of the CSI reference resource when there is a plurality of such first descending link slots that correspond to the ascending link slot.

[00150] Additionally, a more recent first downlink slot is selected as the location of the CSI reference resource in the time domain when there are at least two first downlink slots that correspond to the first uplink slot. Petition 870200132292, dated 10 / 20 / 2020, page 41 / 134 36 / 45

[00151] In other words, a more recent slot is selected as the time domain location of the CSI reference resource when there exists a plurality of such first downlink slots that correspond to the first uplink slot.

[00152] Alternatively, a more recent valid first downlink slot is selected as the location of the CSI reference resource in the time domain when there are at least two first downlink slots that match the first uplink slot.

[00153] In other words, a more recent valid downlink slot is selected as the timedomain location of the CSI reference resource when there exists a plurality of such first downlink slots that correspond to the first uplink slot.

[00154] Alternatively, the location of the CSI reference resource in the time domain is determined based on the first uplink slot and slot offset when there are at least two first downlink slots that correspond to the first uplink slot.

[00155] In other words, when there is a plurality of such first downlink slots that correspond to the first uplink slot, a calculation formula, the first uplink slot and the slot offset can be predefined to calculate and obtain the location of the CSI reference feature in the time domain. Petition 870200132292, dated 10 / 20 / 2020, page 42 / 134 37 / 45

[00156] Alternatively, when there are at least two first downlink slots that correspond to the first uplink slot, a corresponding downlink slot is selected as a location for a CSI reference resource of at least two BWP bandwidth parts in the time domain based on at least one of the following ways:

[00157] select a first earliest descending link slot as the location of the CSI reference resource in the time domain;

[00158] select a first valid earliest descending link slot as the location of the CSI reference resource in the time domain;

[00159] select a first most recent downlink slot as the location of the CSI reference resource in the time domain; and

[00160] select the most recent valid downlink first slot as the location of the CSI reference resource in the time domain.

[00161] In other words, when there is a plurality of downlink slots that correspond to the uplink slot, a corresponding downlink slot is selected as the timedomain location of the CSI reference resource respectively according to the four ways described above. It should be noted that at least one of the four ways described above can be used.

[00162] Situation 2: The first processing unit 21 is configured to: determine a second downlink slot that corresponds to a first slot Petition 870200132292, dated 10 / 20 / 2020, pp. 43 / 134 38 / 45 of the uplink slot at the time of PUCCH reporting or at the time of PUSCH reporting; and subtract the slot offset from the second downlink slot, and use a third downlink slot obtained as the location of the CSI reference resource in the time domain.

[00163] In other words, when slot offset is obtained in the previous Mode 2, a downlink slot n' (second downlink slot) that corresponds to slot n (first uplink slot) is first obtained, and a slot, in which nCQI_ref before the downlink slot n' (second downlink slot) is located, i.e., n'-nCQI_ref, is selected as the time domain location of the CSI reference feature.

[00164] Additionally, a second priority downlink slot is selected for calculation of the third downlink slot when there are at least two second downlink slots that correspond to the first uplink slot.

[00165] In other words, a priority downlink slot n' is selected for CSI reference resource calculation when there is a plurality of downlink slots n' (second downlink slots) that corresponds to uplink slot n (first uplink slot).

[00166] Alternatively, a last second priority downlink slot is selected for calculation of the third downlink slot when there are at least two second downlink slots that correspond to the first uplink slot. Petition 870200132292, dated 10 / 20 / 2020, page 44 / 134 39 / 45

[00167] In other words, a final downlink slot n' is selected for calculation of the third downlink slot to determine the CSI reference resource when there is a plurality of downlink slots n' (second downlink slots) that corresponds to the uplink slot n (first uplink slot).

[00168] Alternatively, the location of the CSI reference resource in the time domain is determined based on the first uplink slot and the slot offset when there are at least two second downlink slots that correspond to the first uplink slot. In other words, a predefined calculation formula can be used to perform the calculation when there is a plurality of second downlink slots that correspond to the first uplink slot.

[00169] Situation 3: The first processing unit 21 is configured to: determine a subcarrier spacing that corresponds to the slot offset to be a downlink subcarrier spacing or an uplink subcarrier spacing, and, if the subcarrier spacing is a downlink subcarrier spacing, calculate the location of the CSI reference feature in the time domain based on one of the following methods:

[00170] determine the location of the CSI reference resource in the time domain based on the first uplink slot and slot offset;

[00171] select a first earliest descending link slot as the resource location Petition 870200132292, dated 10 / 20 / 2020, page 45 / 134 40 / 45 CSI reference in the time domain;

[00172] select a first valid earliest downlink slot as the location of the CSI reference resource in the time domain;

[00173] select a first most recent downlink slot as the location of the CSI reference resource in the time domain; and

[00174] select the most recent valid downlink first slot as the location of the CSI reference resource in the time domain.

[00175] In other words, when the slot offset is obtained through calculation based on the previous Mode 3, a subcarrier spacing, which corresponds to nCQI_ref, is first determined to be a downlink subcarrier spacing or an uplink subcarrier spacing, and, if the subcarrier spacing is a downlink subcarrier spacing, the time-domain location of the CSI reference feature is calculated according to at least one of several methods described above.

[00176] In addition, the first processing unit 21 is configured to: determine a subcarrier spacing that corresponds to the slot offset to be a descending link subcarrier spacing or an ascending link subcarrier spacing, and, if the subcarrier spacing is an ascending link subcarrier spacing, select the earliest descending link slot as the location of the CSI reference feature in the time domain. In other words, if the subcarrier spacing that corresponds to the offset Petition 870200132292, dated 10 / 20 / 2020, page 46 / 134 41 / 45 slot for an uplink subcarrier spacing, the time-domain location of the CSI reference resource is calculated according to the method where the first earliest downlink slot is selected as the location of the CSI reference resource in the time domain.

[00177] Finally, the first processing unit 21 is configured to: calculate CSI according to a given time domain location of the CSI reference resource, and perform the report using a PUCCH or PUSCH resource.

[00178] It can be learned that, in the solution described above, a slot offset value of a CSI reference resource relative to a reporting moment can be obtained using a downlink measurement resource configuration and an uplink reporting resource configuration that are included in the CSI reporting configuration information, and, additionally, a location of the CSI reference resource in a time domain is determined based on the slot offset. In this way, the accuracy of the calculation for CSI is guaranteed and the processing efficiency of the system is improved. MODE 11

[00179] This embodiment of the present invention provides a network device, including: a second communications unit configured to send at least one first piece of information to a terminal device, wherein the first piece of information carries at least CSI report configuration information, and the CSI report configuration information includes at least one feature configuration. Petition 870200132292, dated 10 / 20 / 2020, page 47 / 134 42 / 45 downlink measurement and an uplink reporting feature configuration.

[00180] Specifically, CSI report configuration information additionally includes: CSI reporting that is at least one of the following: periodic report, quasi-periodic report, and aperiodic report.

Certainly, the PUCCH or PUSCH resource setting may additionally include other parameters, however, the parameters are not exhaustively listed in this mode.

[00184] Correspondingly, on one end device side, a slot offset can be determined based on the downlink measurement resource configuration and the uplink reporting resource configuration that are included in the CSI reporting configuration information, and additionally, a location of a CSI reference resource in a domain.

That is, a terminal determines the location of the CSI reference resource in the time domain according to slot n (first uplink slot) and nCQI_ref at PUCCH reporting time or PUSCH reporting time, calculates the CSI according to a given time domain location of the CSI reference resource, and performs the report using a PUCCH or PUSCH resource.

[00185] It can be learned that, in the solution described above, the terminal device can be enabled to obtain a slot offset value of a CSI reference resource relative to a reporting moment using a downlink measurement resource configuration and an uplink reporting resource configuration that are included in the CSI reporting configuration information, and additionally determine a location of the CSI reference resource in a time domain based on the slot offset. In this way, the accuracy of the calculation for CSI is guaranteed and the processing efficiency of the system is improved.
