[0170] FIG. 2 is a flowchart of a time point determination method provided by an embodiment of the present disclosure. It should be understood that the time point determination method provided by the embodiments of the present disclosure can be applied to the terminal device in the scenarios as described above.

[0171] As shown in FIG. 2, the time point determination method provided by the embodiments of the present disclosure includes the following steps:

[0172] S201, acquire first information.

[0173] It should be noted that the manner of acquiring the first information is not limited in the embodiments of the present disclosure. For example, the first information can be configured or indicated to the terminal device by the network device, or the first information can also be determined by the terminal device.

[0174] Please refer to FIG. 3, which is a schematic diagram of CSI reporting according to an embodiment of the present disclosure. As shown in FIG. 3, M1-M4 are time instants at which CSI measurement resources are located. The terminal device is configured to predict N1-N4 based on the CSI measurement resources, and report CSI at N' time instant, so as to report the prediction results corresponding to one or more time instants associated with the CSI reporting to the network device. For example, the one or more time instants associated with the reported prediction results are N1, N2 and N3, which are the time instants associated with the CSI reporting, wherein N1 is the first reporting time instant associated with the CSI reporting.

[0175] In an implementation, the first information includes a first time. The first time is the first reporting time instant associated with the CSI reporting. The first time is obtained according to a reference time and a time offset, and the reference time is obtained based on a CSI reporting time slot.

[0176] In another implementation, the first information includes the first time and time configuration information.

[0177] The time configuration information is configured or indicated to the terminal device by the network device. In some embodiments, the time configuration information includes at least one of the following, but is not limited to:

[0178] a first number p of time instants associated with the CSI reporting and a time interval d between two consecutive time instants;

[0179] a prediction duration t associated with the CSI reporting and a time interval d between two consecutive time instants.

[0180] The first number p of time instants associated with the CSI reporting, i.e., the number of time instants configured by the network device for the terminal device to report CSI, for example, when the first number p is 3, it means that the terminal device needs to report the prediction results of 3 prediction time instants;

[0181] The time interval d between two consecutive time instants, i.e., the time interval between two adjacent time instants configured by the network device for the terminal device to report CSI, for example, in the above FIG. 3, the time interval d can be the time interval between N1 and N2, or the time interval between N2 and N3, or the time interval between N3 and N4;

[0182] The prediction duration t associated with the CSI reporting is a duration of a prediction time configured by the network device for the terminal device to perform CSI reporting, for example, in FIG. 3, the prediction duration t configured by the network device is a duration between the starting time slot N1 and the ending time slot N3.

[0183] In some embodiments, the first time is a sum of the reference time and the time offset. For example, referring to FIG. 3, the CSI measurement resource is in the time slot of the reference time n and the time offset f, and the first time m (or the first reporting time N1) can be determined according to the sum of the reference time n and the time offset f.

[0184] Next, the determination method of the reference time and the time offset is described in combination with embodiments.

[0185] In some embodiments, the reference time can be determined by the following method 1 or method 2:

[0186] Method 1 for determining the reference time:

[0187] In the method 1 for determining the reference time, the reference time is a transmission time slot or a transmission frame of a CSI resource in the CSI resource set that is closest to the CSI reporting time slot and not later than the CSI reporting time slot.

[0188] In this embodiment, it is assumed that the terminal device has a BM-Case2 model capability, if the network device configures the terminal device to report the prediction results of multiple time points, for example, the network device indicates the first number p of time points associated with the CSI reporting of the terminal device, or indicates the prediction duration t associated with the CSI reporting of the terminal device, the terminal device considers that the model-based inference result is needed to report the prediction result of the model.

[0189] In the above method 1 for determining the reference time, for the case that the CSI reporting is associated with a CSI resource set, the terminal device can determine all CSI measurement resources required for one inference through the CSI resource set, at this time, the determination method of the reference time includes but is not limited to the following method 1 and method 2:

[0190] Method 1, the terminal device can determine the transmission time slot of the CSI measurement resource closest to the CSI reporting time slot and not later than the CSI reporting time slot as the first time according to the predefinition.

[0191] Method 2, the terminal device determines the transmission time slot of the CSI measurement resource closest to the CSI reporting time slot and not later than the CSI reporting time slot as the first time according to the indication or configuration of the network device.

[0192] Please continue to refer to FIG. 3, assuming that the network device configures the CSI reporting to be associated with a CSI resource set, and the terminal device determines the CSI measurement resource at M1-M4 according to the CSI resource set, and the network device configures the CSI reporting at time N', according to FIG. 3, the CSI measurement resource closest to the CSI reporting time and not later than the CSI reporting is the CSI measurement resource at time M4. At this time, the terminal device can determine the reference time n associated with the CSI reporting to be the time slot m4 of the CSI measurement resource at time M4 according to the predefinition or the configuration or indication of the network device, that is, the time slot slot n of the reference time n is slot m4.

[0193] In the above-mentioned method one of determining the reference time, when the number of CSI resource sets is multiple or the CSI resource set includes multiple sub-sets, the terminal device can determine the CSI measurement resource at one time required by one inference through each CSI resource set configuration or CSI resource sub-set configuration. For example, the terminal device determines the CSI measurement resource at time M1 through the CSI resource set 1 or the CSI resource sub-set 1, determines the CSI measurement resource at time M2 through the CSI resource set 2 or the CSI resource sub-set 2, and so on, to determine the corresponding CSI measurement resource at each time. At this time, the reference time includes but is not limited to the following way 1 and way 2:

[0194] Way 1, the reference time is: the transmission time slot or transmission frame of the CSI resource closest to the CSI reporting time slot and not later than the CSI reporting time slot in the multiple CSI resource sets and / or multiple sub-sets.

[0195] The terminal device reports the CSI measurement resource determined by all CSI resource sets or CSI resource subsets associated with the CSI reporting as the reference CSI measurement resource. In some embodiments, the terminal device can determine the transmission time slot of the reference CSI measurement resource closest to the CSI reporting time slot and no later than the CSI reporting time slot according to a predefinition. Alternatively, the terminal device can determine the transmission time slot of the reference CSI measurement resource closest to the CSI reporting time slot and no later than the CSI reporting time slot according to an indication or configuration of the network device. Please continue to refer to FIG. 3. As shown in FIG. 3, it is assumed that the network device configures the CSI reporting to be associated with 4 CSI resource sets / subsets, each of which corresponds to a measurement CSI resource at one time point required for one inference, and the terminal device determines the CSI resource indicated by the 4 resource sets / subsets as the reference CSI measurement resource. If the network device configures the CSI reporting to be at time point N', the CSI measurement resource closest to the CSI reporting time and no later than the CSI reporting is at time point M4. At this time, the terminal device determines the reference time n associated with the CSI reporting to be the time slot m4 of the CSI measurement resource at time point M4, i.e., the reference time slot n = slot m4.

[0196] Option 2: The reference time is the transmission time slot or transmission frame of the CSI measurement resource in the reference CSI measurement resource in the plurality of CSI resource sets and / or the plurality of subsets closest to the CSI reporting time slot and no later than the CSI reporting time slot.

[0197] The reference CSI measurement resource is predefined or configured or indicated by the network device.

[0198] When the reference CSI measurement resource is predefined, the predefined reference CSI measurement resource includes but is not limited to the following case 1 and case 2:

[0199] Case 1: The last time point corresponding to the CSI measurement resource set or subset required for one inference;

[0200] Case 2: The CSI measurement resource set or subset with the maximum index or the minimum index.

[0201] In some embodiments, example 1, when the reference CSI measurement resource is predefined, the terminal device can be predefined to report the CSI associated with one CSI resource set or subset as the reference CSI measurement resource. In some embodiments, the last time point corresponding to the CSI measurement resource set / subset required for one inference can be predefined as the candidate CSI measurement resource of the first reference time. Alternatively, the CSI resource set / subset with the minimum or maximum index can be predefined as the candidate CSI measurement resource of the first reference time.

[0202] Correspondingly, the terminal device takes, in the reference CSI measurement resource, a CSI resource transmission time slot closest to the CSI reporting and no later than the CSI reporting as the reference time n. Please continue to refer to FIG. 3. As shown in FIG. 3, the last time required for one inference associated with the CSI reporting is N4, which corresponds to the CSI resource set 4 or the sub-resource set 4. If the terminal device takes the CSI resource set 4 or the sub-resource set 4 as the reference CSI measurement resource, the CSI resource transmission time closest to the CSI reporting and no later than the CSI reporting is M4, which corresponds to the time slot m4. Therefore, the time slot slot n where the reference time n is located is slot m4.

[0203] In example 2, when the network device configures or indicates the reference CSI measurement resource, the network device can configure or indicate the terminal device to take one CSI resource set or sub-set associated with the CSI reporting as the reference CSI measurement resource.

[0204] Correspondingly, the terminal device takes, in the reference CSI resource set, a CSI resource transmission time closest to the CSI reporting and no later than the CSI reporting as the reference time n. For example, the network device configures or indicates the terminal device to take the CSI resource set 2 or the sub-set 2 associated with the CSI reporting as the reference CSI measurement resource. The CSI resource transmission time closest to the CSI reporting and no later than the CSI reporting is M2, which corresponds to the time slot m2. Therefore, the time slot slot n where the reference time n is located is slot m2.

[0205] In some embodiments, in the above method one, the reference time is the starting boundary or the ending boundary of the frame where the CSI reporting time slot is located.

[0206] In some embodiments, when the reference time is determined by using the above method one, the value range of the time offset is predefined or determined according to the capability of the terminal device, and the value of the time offset is a value greater than or equal to 0. In some embodiments, when the reference time is determined by using the above method one, the time offset includes but is not limited to at least one of the following a-e:

[0207] a. The time offset is an offset in time slots, i.e., slot-level.

[0208] In some embodiments, the network device can configure or indicate the terminal device to use the offset in time slots. The value range of the offset in time slots is {0, 1, 2,.., F1}. In some embodiments, the value range of the offset in time slots is obtained according to the subcarrier spacing. For example, F1ref corresponding to 15Khz is taken as the reference value, and the subcarrier spacing is 15x2 n Therefore, F1 is 2.n (Fref+1)-1, wherein (Fref+1) is the maximum offset, and exemplary, when the subcarrier spacing is 15Khz, the maximum offset is 40ms, the value of F1 is 39; when the subcarrier spacing is 30Khz (i.e. n is 1), the value of F1 is 79; when the subcarrier spacing is 60Khz (i.e. n is 2), the value of F1 is 159, and so on, so as to obtain the value of F1 corresponding to different subcarrier spacing.

[0209] b. The time offset is an extended offset, and the extended offset is an integer multiple of the offset in time slots.

[0210] The extended offset is obtained according to the reference subcarrier spacing, the subcarrier spacing corresponding to the carrier measured by the terminal device, and the offset in time slots.

[0211] Exemplarily, the offset in time slots is extended to an X-slot level offset. In some embodiments, a reference subcarrier spacing SCS ref is used to determine the subcarrier spacing SCS target of the target carrier, and the above-mentioned extension multiple X is determined. Wherein, X can be the ratio of the subcarrier spacing SCS target of the target carrier to the reference subcarrier spacing SCS ref , that is, For example, taking the reference subcarrier spacing as 120KHz and the subcarrier spacing of the target carrier as 480KHz as an example, the above-mentioned extension multiple X is 4, that is, the extended offset is 4slot level.

[0212] c. The time offset is an offset in a first parameter;

[0213] In some embodiments, the first parameter includes a minimum measurement time or a minimum prediction time. That is, the time offset is an offset in the minimum measurement time (or D-level); or, the time offset is an offset in the minimum time interval (or M-level).

[0214] Wherein, the minimum measurement time is the minimum time interval between the transmission of two adjacent CSI resources, or the minimum time interval between the two adjacent CSI measurement resource sets or sub-sets associated with the CSI reporting. Exemplarily, if the network device configures or instructs the terminal device to use the M-level offset, and taking the minimum time interval of two adjacent CSI resources in a CSI measurement set associated with the CSI reporting as 40ms as an example, M represents the time unit of 40ms. In addition, if the value range of M is {0, 1, 2,.., F1}, if the value of M is 2, the time offset is 80ms.

[0215] wherein the minimum prediction time is a time interval between two consecutive time instants in a CSI reporting. For example, if the network device configures or indicates the terminal device with a D-level offset, wherein the D-level refers to a time interval d between two consecutive prediction time instants associated with a CSI reporting. For example, if the time interval d between two consecutive prediction time instants associated with a CSI reporting is 40 ms, then D represents a time unit of 40 ms. In addition, if the value range of D is {0, 1, 2,.., F1}, if the value of D is 3, then the time offset is 120 ms.

[0216] In some embodiments, the first parameter is obtained by at least one of the following ways:

[0217] the first parameter is configured by a higher layer;

[0218] the first parameter is obtained according to the capability of the time-domain prediction model of the terminal device;

[0219] the first parameter is determined by a model feature parameter configured or indicated by the network device.

[0220] d, the time offset is a parameter associated with the capability or the activated model of the time-domain prediction model reported by the terminal device.

[0221] In some embodiments, the network device configures or indicates the terminal device to perform a time-domain prediction model associated with a CSI reporting, and accordingly, the terminal device has reported the CSI measurement resource time instant and the corresponding CSI prediction time instant in the capability reporting process, i.e., when the input of the time-domain prediction model is M1-M4, the corresponding prediction output value is N1-N4. Therefore, in this embodiment, the terminal device can determine the value of the time offset according to the parameter associated with the capability or the activated model of the time-domain prediction model, i.e., implicitly obtain the value of the time offset without the configuration or indication of the network device.

[0222] e, the time offset is the sum of a first offset and a second offset, the first offset is at least one of a frame-based offset, a first parameter-based offset, and the second offset is a slot-based offset or an extended offset.

[0223] The first offset can also be referred to as a first granularity, and the second offset can also be referred to as a second granularity. In some examples, taking the frame boundary of frame n or the slot n as the reference time, and taking the offset in the unit of frame as the first offset (i.e., the first offset is frame-level) and the offset in the unit of slot as the second offset (i.e., the second offset is slot-level) as examples, in a subcarrier interval of 15 kHz, the network device configures the value corresponding to the frame-level as 2, and the value corresponding to the slot-level as 8. Then, the terminal device can determine the time offset f as 2frame+8slot=28 ms. In addition, the value range of the frame-level is {0, 1, 2,.., F1}, and the value range of the slot-level is {0, 1, 2,.., F2}, where the maximum time of the value of F2 is frame, and the value of F2 is related to the subcarrier interval. For example, when the subcarrier interval is 15 kHz, the value of the frame-level is 9, when the subcarrier interval is 30 kHz, the value of the frame-level is 19, and so on.

[0224] In some examples, taking the offset in the unit of minimum measurement time as the first offset (i.e., the first offset is M-level) and the offset in the unit of slot as the second offset (i.e., the second offset is slot-level) as examples. Taking the reference time n as the starting point, in a subcarrier interval of 15 kHz, the network device configures the value corresponding to the M-level as 1, and the value corresponding to the slot-level as 8, and the value of M is 40. Then, the terminal device can determine the time offset f as 2M+8slot=88 ms. In addition, the value range of the M-level is {0, 1, 2,.., F1}, and the value range of the slot-level is {0, 1, 2,.., F2}, and the maximum time of the value of F2 is M, and the value of F2 is related to the subcarrier interval. For example, the value of F2 corresponding to 15 kHz is 79, and the value of F2 corresponding to 30 kHz is 159, where the determination manner of F2 is similar to the determination manner of F1 in the above embodiment, which is not described herein.

[0225] In some examples, the first offset is an offset in units of minimum prediction time (i.e., the first offset is D-level), and the second offset is an offset in units of time slot (i.e., the second offset is slot-level). Taking the reference time n as the starting point, in the subcarrier interval 15 kHz, the value of D-level configured by the network device is 1, the value of slot-level is 8, and the value of D is 40. Then, the terminal device can determine the time offset f as 2M+8slot=88ms. In addition, the value range of D-level is {0, 1, 2,.., F1}, and the value range of slot-level is {0, 1, 2,.., F2}. The maximum time value of F2 is D, and the value of F2 is related to the subcarrier interval. For example, the value of F2 corresponding to 15 kHz is 79, and the value of F2 corresponding to 30 kHz is 159. The determination manner of F2 is similar to the determination manner of F1 in the above-mentioned embodiments, which is not described herein.

[0226] It should be noted that when the second offset is an extended offset, the determination manner of the time offset is similar to the calculation manner of the second offset being slot-level in the above-mentioned example one, example two, and example three, which is not described herein.

[0227] Method two for determining the reference time:

[0228] In the method two for determining the reference time, the reference time includes but is not limited to the following cases 1 and 2:

[0229] Case 1: The reference time is a CSI reporting time slot or a frame in which the CSI reporting time slot is located.

[0230] Case 2: A time slot or a frame in which a CSI reference resource associated with the CSI reporting time slot is located.

[0231] In some embodiments, the reference time is a CSI reporting time slot slot n or a frame frame n in which the CSI reporting time slot is located.

[0232] Or, a time slot slot n in which a CSI reference resource associated with the CSI reporting time slot is located, or a frame frame n in which the time slot is located. For the frame n, the starting frame boundary of the frame n can be taken as the starting point of the reference time according to predefinition or configuration or indication of the terminal device by the network device, or the ending frame boundary of the frame n can be taken as the starting point of the reference time. Please refer to FIG. 4, which is a schematic diagram two of the principle of CSI reporting provided by an embodiment of the present disclosure. As shown in FIG. 4, in the method two for determining the reference time, the reference time n is a CSI reporting time slot N' or a frame in which the CSI reporting time slot N' is located.

[0233] In some embodiments, when the reference time is determined by the above-mentioned method two, the time offset is a predefined value or determined according to the capability of the terminal device, and the value of the time offset is a value less than 0, greater than 0, or equal to 0.

[0234] In some embodiments, when the reference time is determined by the above-mentioned method two, if the time associated with the CSI reporting is not earlier than the time slot in which the CSI reporting is located, please refer to FIG. 4, as shown in FIG. 4, the time associated with the CSI reporting is N1, N2, and N3, which are not earlier than the time slot in which the CSI reporting is located. At this time, the time offset f can be determined in a similar manner as in the above-mentioned method one, and the first time m (or the first reporting time N1) is determined according to the sum of the time offset f and the reference time n, which will not be described here.

[0235] In some embodiments, when the reference time is determined by the above-mentioned method two, if the time associated with the CSI reporting is earlier than the time slot in which the CSI reporting is located (please refer to FIG. 5, which is a schematic diagram three of the principle of CSI reporting provided by an embodiment of the present disclosure), as shown in FIG. 5, the reference time n is the time slot N' of the CSI reporting or the frame in which the time slot N' of the CSI reporting is located, and the time associated with the CSI reporting is N1, N2, and N3, wherein N1 is earlier than the time slot N' in which the CSI reporting is located. At this time, the time offset f can be determined according to at least one of the following a-c, and the first time m (or the first reporting time N1) is determined according to the sum of the time offset f and the reference time n:

[0236] a. The time offset is an offset in time slots;

[0237] Wherein, the value range of the offset in time slots is obtained according to the subcarrier spacing.

[0238] In some embodiments, the network device configures or instructs the terminal device that the time offset is an offset in time slots (i.e. slot-level), and the value range is {-F1',..., -1, 0, 1, 2,..., F1}. For example, when the network device configures or instructs the time offset to be a value less than or equal to 0, for example, -10slot, the terminal device can take the reference time slot n as the starting point, and determine the time slot 10 slots earlier than the reference time as the first time. That is, the first time slot m = slot n-10slot. Alternatively, if the terminal device takes the starting frame boundary of the reference time frame n as the starting point, and determines the time of 10 slots as the first time, that is, slot m = frame(n-1)-10slot.

[0239] It should be noted that the value of F1 and F1' is related to the subcarrier spacing. In some embodiments, when the subcarrier spacing is 15Khz and the maximum offset is 40ms, the value of F1 is 39; when the subcarrier spacing is 30Khz (i.e., n is 1), the value of F1 is 79; when the subcarrier spacing is 60Khz (i.e., n is 2), the value of F1 corresponds to 159, and so on, that is, the value of F1 corresponding to different subcarrier spacing can be obtained.

[0240] b. The time offset is an extended offset, and the extended offset is an integer multiple of the offset in time slots;

[0241] The extended offset is obtained according to the reference subcarrier spacing, the subcarrier spacing corresponding to the carrier measured by the terminal device, and the offset in time slots.

[0242] It should be noted that the extended offset can be determined in a similar manner as in method 1 described above, which will not be described here.

[0243] c. The time offset is the sum of the first offset and the second offset, the first offset is at least one of the offset in frames, the offset in the first parameter, and the second offset is the offset in time slots or the extended offset.

[0244] The first offset can also be referred to as the first level granularity, and the second offset can also be referred to as the second level granularity.

[0245] In some examples, the first offset is the offset in frames (i.e., the first offset is frame-level), the second offset is the offset in time slots (i.e., the second offset is slot-level), the value range of frame-level is {-F1',..., -1, 0, 1, 2,..., F1}, the value range of slot-level is {-F2',..., -1, 0, 1, 2,..., F2}, and the reference time is the frame edge of frame n or slot n. In the subcarrier spacing of 15Khz, the network device configures the value corresponding to frame-level as -2, and the value corresponding to slot-level as -8. Then the terminal device can determine the time offset f as (-2frame) + (-8slot) = -28ms.

[0246] In some examples, taking the first offset as an offset in the unit of minimum measurement time (i.e., the first offset is M-level), the second offset as an offset in the unit of slot (i.e., the second offset is slot-level), and the reference time as the frame edge of frame n or slot n as examples, in a subcarrier spacing of 15Khz, when the value of M is 40, the value of M-level configured by the network device is -2, and the value of slot-level is -8, the terminal device can determine the time offset f as -2M+(-8slot) = 88ms.

[0247] In some examples, taking the first offset as an offset in the unit of minimum prediction time (i.e., the first offset is D-level), the second offset as an offset in the unit of slot (i.e., the second offset is slot-level), and the reference time as the frame edge of frame n or slot n as examples, in a subcarrier spacing of 15Khz, when the value of D is 40, the value of D-level configured by the network device is -2, and the value of slot-level is -8, the terminal device can determine the time offset f as -2D+(-8slot) = 88ms.

[0248] It should be noted that when the second offset is an extended offset, the manner of determining the time offset is similar to the calculation manner when the second offset is slot-level in the above examples, which will not be described here

[0249] S202, determining one or more time instants associated with the CSI reporting according to the first information.

[0250] In some embodiments, when the first information only includes the first time, the above step S202 is: determining the first reporting time instant associated with the CSI reporting according to the first information, wherein the first time is the first reporting time instant of the CSI reporting.

[0251] In some embodiments, when the first information includes the first time and the time configuration information, and the time instant associated with the CSI reporting is not earlier than the time slot in which the CSI reporting is located (for example, in the above FIG. 3 and FIG. 4, the time instants associated with the CSI reporting are N1, N2 and N3, all of which are not earlier than the time slot in which the CSI reporting is located), at this time, the above step S202 includes but is not limited to the following case 1 and case 2:

[0252] Case 1, determining one or more time instants associated with the CSI reporting according to the first time m, the first number p of time instants associated with the CSI reporting, and the time interval d between two consecutive time instants.

[0253] Case 2: determining one or more time instants associated with the CSI reporting according to the first time m, the prediction duration t associated with the CSI reporting and the time interval d between two consecutive time instants.

[0254] In some embodiments, in the above case 1, after determining the first time m, the terminal device determines the time positions of the remaining time instants, taking the first time m as the starting time instant. For example, in FIG. 3, if the terminal device determines that the first time m is time instant N1, and the value of the first quantity p is 3 and the time interval d between two consecutive time instants is 40 ms, then the terminal device determines that the time instants associated with the CSI reporting are N1, N2 and N3, where N2 is a time instant that is 40 ms away from N1, and N3 is a time instant that is 40 ms away from N2.

[0255] In some embodiments, in the above case 2, after determining the first time m, the terminal device determines the time positions of the remaining time instants, taking the first time m as the starting time instant. For example, in FIG. 3, if the terminal device determines that the first time m is time instant N1, and the prediction duration t is 120 ms and the time interval d between two consecutive time instants is 40 ms, then the terminal device determines that the time instants associated with the CSI reporting are N1, N2 and N3, where N2 is a time instant that is 40 ms away from N1, and N3 is a time instant that is 40 ms away from N2, and the duration between the starting time slot of N1 and the ending time slot of N3 is 120 ms.

[0256] In some embodiments, when the first information includes the first time m and the time configuration information, and the time instants associated with the CSI reporting are earlier than the time slot in which the CSI reporting is performed (for example, in FIG. 5, the time instants associated with the CSI reporting are N1, N2 and N3, where N1 is earlier than the time slot in which the CSI reporting is performed), then the above step S202 includes but is not limited to the following case 1 and case 2:

[0257] Case 1: the network device configures or instructs the terminal device to perform CSI reporting associated with the first quantity p of time instants and the time interval d between two consecutive time instants.

[0258] Case 2: the network device configures or instructs the terminal device to perform CSI reporting associated with the prediction duration t and the time interval d between two consecutive time instants. After determining the first time, the terminal device determines the first reporting time instant N1 taking the first time m as the first reporting time instant N1, and determines the remaining time instants.

[0259] In some embodiments, in case 1 above, the terminal device determines a first time m as a first reporting time N1 after determining the first time, and determines the remaining time. Taking FIG. 5 as an example, the CSI reporting time is N', the first time m is determined as time N1 starting from N', and N'>N1. When the first number p is 3 and the time interval d between two consecutive times is 40 ms, the terminal device can determine that the CSI reporting associated times are N1, N2 and N3.

[0260] In case 2 above, taking FIG. 5 as an example, the CSI reporting time is N', the first time m is determined as time N1 starting from N', and N'>N1. Taking the prediction duration t as 120 ms and the time interval d as 40 ms as an example, the terminal device determines that the CSI reporting associated times are N1, N2 and N3.

[0261] Through the scheme provided by the embodiments of the present disclosure, the terminal device can accurately determine one or more times associated with CSI reporting, thereby performing CSI reporting.

[0262] In the present embodiment, the network device can inform the terminal device of the time that needs to be reported by configuration or indication. The terminal device does not need to report the prediction time that is not required by the network device, so that the network device and the terminal device can align the reporting content.

[0263] FIG. 6 is a signaling interaction diagram of a time determination method provided by an embodiment of the present disclosure. As shown in FIG. 5, the time determination method includes the following steps:

[0264] S601, the network device configures or indicates first information for the terminal device.

[0265] S602, the terminal device determines one or more times associated with CSI reporting according to the first information.

[0266] The implementation of steps S601 and S602 is similar to that of steps S201-S202 in the embodiment shown in FIG. 2, and the related content in the above embodiments can be referred to, which will not be repeated here.

[0267] S603, the terminal device determines a reporting time from the one or more times.

[0268] When the terminal device performs CSI reporting, it needs to report the prediction result corresponding to the reporting time in the reported report.

[0269] In some embodiments, the network device can indicate the reporting time that needs to be reported by the terminal device, wherein the reporting time includes but is not limited to the following case 1 and case 2:

[0270] Case 1: the reporting time is one or more times described above.

[0271] That is, the terminal device can determine, according to the configuration or indication of the network device, all one or more time instants associated with the CSI determined in step S502 as the time instants that need to be reported. For the determination method of the first or multiple time instants, please refer to the related content in the embodiment of FIG. 2, which will not be repeated here.

[0272] Case 2, the reporting time instant is a time instant in the one or more time instants described above, which is not earlier than the CSI reporting time slot.

[0273] That is, if the first time associated with the CSI reporting is the time slot in which the latest CSI resource transmission in the CSI resource set associated with the CSI reporting is not later than the CSI reporting, that is, the reference time determined by the above method 1 determines the first time, the terminal device determines the reporting time instant according to the configuration or indication of the network device.

[0274] Among them, for one or more time instants associated with the CSI reporting, if a certain time instant is not earlier than the CSI reporting time slot, the terminal device will report the prediction result corresponding to this time instant; if a certain time instant is earlier than the CSI reporting time slot, the terminal device will omit the prediction result corresponding to the prediction time instant, that is, the prediction result of the time instant will not be reported.

[0275] For example, please refer to FIG. 7, which is a schematic diagram of the principle of CSI reporting provided by an embodiment of the present disclosure. As shown in FIG. 7, if the terminal device determines that the one or more time instants associated with the CSI reporting are N1, N2 and N3, the time slot in which the CSI reporting is located is N' (wherein N2

[0276] In some embodiments, the terminal device can determine the reporting time instant that needs to be reported from one or more time instants. The terminal device determines the reporting time instant in the following ways, including but not limited to way 1, way 2 and way 3:

[0277] Way 1, the terminal device can determine the reporting time instant from one or more time instants according to a preset requirement.

[0278] In some embodiments, in way 1, the reporting time instant includes but is not limited to the following case 1 and case 2:

[0279] Case 1, a time instant in the one or more time instants that meets the preset requirement;

[0280] In case 1, the reporting time meeting the preset requirement includes, but is not limited to, the following ①-③:

[0281] ① According to the accuracy of the time domain prediction model of the terminal device, the reporting time meeting the preset requirement is determined from the one or more time instants associated with the CSI. The accuracy of the time domain prediction model is determined according to the probability or reliability of the prediction result, that is, the reporting time meeting the preset requirement can be determined from the one or more time instants according to the probability or reliability of the prediction result of each time instant.

[0282] For example, with a probability threshold of 80%, for example, the probability of the prediction result of each time instant in the one or more time instants is {90%, 91%, 90%, 84%, 69%, 69%, 69%, 60%}, the terminal device determines the reporting time as the time instant with a probability greater than the 80% threshold, that is, the reporting time is the first, second, third, and fourth time instants, and the terminal device reports the prediction results corresponding to these reporting time instants.

[0283] ② According to the motion trajectory of the terminal device, the reporting time meeting the preset requirement is determined from the one or more time instants associated with the CSI.

[0284] For example, it is assumed that the terminal device is in low-speed motion in the first three time instants and is in high-speed motion in the last five time instants, and the terminal device can determine that the prediction results of the first four time instants are reliable under this motion trajectory, and the terminal device determines the reporting time as the first four time instants and reports the prediction results corresponding to the first four time instants.

[0285] ③ According to the energy saving state of the terminal device, the reporting time meeting the preset requirement is determined from the one or more time instants associated with the CSI.

[0286] For example, if the network device configures the terminal device with a second number p2, if the terminal device is in an energy saving state, the terminal device can determine the number of reporting time instants as p1, where p1 is a value determined by the terminal device; if the terminal device is in a non-energy saving state, the terminal device determines the number of reporting time instants as p2 according to the configuration of the network device, where the value of p2 is greater than p1.

[0287] Case 2: The time instant in the one or more time instants is not earlier than the CSI reporting time slot and meets the preset requirement.

[0288] That is, in case 2, the time instant not earlier than the CSI reporting time slot can be determined from the one or more time instants, and the time instant meeting the preset requirement is determined from the time instants not earlier than the CSI reporting time slot as the reporting time.

[0289] The method for determining the time from the one or more times that is not earlier than the CSI reporting time slot and the method for determining the time that meets the preset requirement from the times are described above and will not be repeated here.

[0290] In mode 2, the terminal device can determine the reporting time according to the second quantity.

[0291] In some embodiments, the terminal device can determine the second quantity of times from the one or more times associated with CSI reporting as the reporting time. The second quantity can be configured or indicated by the network device, or the second quantity can be determined by the terminal device.

[0292] In mode 3, the terminal device can determine the reporting time according to the preset requirement and the second quantity.

[0293] In some embodiments, the terminal device can first determine the time that meets the preset requirement from the one or more times associated with CSI reporting, and then determine the second quantity of reporting times from the time that meets the preset requirement.

[0294] The method for determining the time that meets the preset requirement from the one or more times associated with CSI reporting is described above and will not be repeated here.

[0295] In S604, CSI reporting is performed according to the reporting time.

[0296] When the terminal device performs CSI reporting, it sends a report to the network device. The report includes the prediction results corresponding to each reporting time. In some embodiments, the report includes but is not limited to the following cases 1, 2, 3 and 4 when the terminal device performs CSI reporting:

[0297] Case 1: When the reporting time is one or more times associated with CSI reporting, the terminal device reports the prediction results corresponding to the one or more times, and the time offset f of the nearest reporting time relative to the first reporting time t report，1 The time offset f of the nearest reporting time relative to the first reporting time report For example, referring to FIG. 3, the reporting times are N1, N2 and N3. The first reporting time is N1, the nearest reporting time to the first reporting time N1 is N2, and the terminal device needs to report the prediction results corresponding to N1, N2 and N3, and the time offset between N2 and N1 when performing CSI reporting.

[0298] Case 2: If the second quantity is configured by the network device, the results corresponding to the second quantity of reporting times that are continuous after the first reporting time N1 are reported.

[0299] Case 3: if the second quantity is determined by the terminal device, and the reporting time is continuous, then the terminal device reports the value of the second quantity, the result corresponding to the reporting time after the first reporting time, and the result corresponding to the reporting time of the second quantity.

[0300] Case 4: if the second quantity is determined by the terminal device, and the reporting time is discontinuous, then the terminal device reports the result corresponding to the reporting time of the second quantity, and the time offset of each reporting time relative to the first reporting time.

[0301] That is, when the terminal device autonomously selects the reporting time to be reported, the terminal device needs to indicate the actual reporting time to the network device. That is, if the actual reporting time of the terminal device is a continuous predicted time, the terminal device can determine the actual reporting time after the first reporting time according to the second quantity. If the actual reporting time of the terminal device is a discontinuous predicted time, the terminal device needs to report the time offset of other reporting times relative to the first reporting time.

[0302] In some embodiments, when the terminal device performs CSI reporting, if the results of multiple continuous reporting times are the same, the terminal device reports the result corresponding to the earliest reporting time in the multiple continuous reporting times.

[0303] In some embodiments, when the predicted results of two or more adjacent reporting times are the same, the terminal device can report the predicted result corresponding to the earlier reporting time, and indicate the time information of the times with the same predicted result. The time information includes the number and position of the times with the same predicted result.

[0304] For example, if the optimal beam predicted by time 1 and time 2 is beam 3, the optimal beam predicted by time 3 is beam 5, and the optimal beam predicted by time 4 is beam 3, the terminal device can report the predicted results of time 1, time 3 and time 4, and the time information of time 2, without reporting the predicted result of time 2.

[0305] Through the scheme provided by the embodiments of the present disclosure, the terminal device can accurately determine one or more times associated with CSI reporting, thereby performing CSI reporting.

[0306] In addition, in the present embodiment, the network device can inform the terminal device of the time to be reported by configuration or indication, and the terminal device does not need to report the predicted time that is not required by the network device, so that the network device and the terminal device can align the reporting content.
