[0096] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0097] In NR, in particular, when the communication frequency band is in frequency range 2 (7 GHz or more), since high-frequency channel attenuation is fast, in order to secure coverage, transmission and reception based on a beam are required to be used.

[0098] In a beam management process, a network device configures a reference signal resource set for beam measurement, a terminal measures reference signal resources in the reference signal resource set, and then reports X reference signal resource identifiers (IDs) and corresponding Layer 1 reference signal receiving powers (L1-RSRPs) and / or Layer 1 signal to interference plus noise ratios (L1-SINRs) with which the X reference signal resources are stronger, where X is a positive integer. The reference signal resource set configured by the network device includes X reference signals, each of which corresponds to a different transmission beam of the network device. For each reference signal, the terminal needs to use all reception beams to measure the reference signal and obtain beam measurement qualities corresponding to all reception beams, respectively, and determine a best beam measurement quality. Therefore, the terminal needs to measure M*N beam pairs, where M is the number of transmission beams of the network device, and N is the number of reception beams of the terminal, and M and N are both positive integers. In addition, if periodic beam measurement reporting is configured, the terminal needs to measure reference signals in each period and report beam quality information.

[0099] An Artificial Intelligence (AI)-based prediction method can reduce the number of beam pairs measured by the terminal. In a time-domain-based beam prediction method, for example, the terminal measures beam quality information in the previous N historical periods, and inputs the beam quality information in the N historical periods into an AI model, and then outputs beam quality information in the next M periods. The relationship between M and N can include two cases as shown in FIGS. 1B and 1C.

[0100] As shown in FIG. 1B, the size of the historical period and the future period is the same. In this case, M+N is taken as a whole time unit, and in this whole time unit, the previous N beam qualities need to be measured, and the next M beam qualities can be predicted by AI. If the AI model inference is deployed at the UE end, there are two methods for beam reporting, especially for reporting beam quality information in the next M periods. One is to report each period separately, and the other is to report the beam quality information in the M periods simultaneously. Because the related art only reports the beam quality information in one period, how to report the beam quality information in the M periods simultaneously is a problem to be solved.

[0101] As shown in FIG. 1C, M short periods are contained in one long period, that is, if the terminal moves at high speed, beam switching can be faster, so the beam change every shorter time is predicted. In this case, the beam quality information of the N+1th long period is still reported, but the beam information of the M short periods (or M-1, because the time of the Mth short period and the time of the N+1th long period overlap, and can be obtained based on the measurement result of the long period, without prediction) in the N+1th long period can be predicted by the AI model. Then, if the beam quality information of the M or M-1 short periods needs to be reported at the same time, how to report is a problem to be solved.

[0102] The embodiment of the present disclosure provides a communication method, a terminal determines first beam information corresponding to M time instances, and sends a beam report to a network device, the beam report includes the first beam information corresponding to the M time instances, and the first beam information includes L1-RSRP of a first beam and time instance identification corresponding to the first beam or the L1-RSRP, so that the network device can determine the L1-RSRP of the first beam and the corresponding time instance based on the beam report, thereby improving the communication efficiency.

[0103] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a communication method, and the above method includes:

[0104] In step S2101, the network device sends first configuration information to the terminal.

[0105] In some embodiments, the terminal receives the first configuration information sent by the network device.

[0106] The first configuration information is used to determine a first reference signal resource set and a second reference signal resource set, the first reference signal resource set includes reference signal resources for measurement, and the measurement value of the reference signal resource in the first reference signal resource set is used as the input of the model, the second reference signal resource set includes reference signal resources corresponding to the beam information output by the model, and the first beam information corresponding to M time instances is determined based on the beam information output by the model. Wherein M is a positive integer greater than 1.

[0107] In some embodiments, the terminal determines the first reference signal resource set and the second reference signal resource set based on the first configuration information sent by the network device. The terminal measures the reference signal resources in the first reference signal resource set to obtain the measurement value of the reference signal resources in the first reference signal resource set; the terminal inputs the measurement value of the reference signal resources in the first reference signal resource set into the AI model for prediction to obtain the beam information of the reference signal resources in the second reference signal resource set.

[0108] For example, taking the beam prediction scenario shown in FIG. 1B as an example, the best beam of each of the M short periods is predicted based on the beam information of the previous N short periods, in which case the first set of reference signal resources can include the reference signal resources corresponding to the N short periods, and the second set of reference signal resources can include the reference signal resources corresponding to the M short periods in the (N+1) long period.

[0109] For another example, taking the beam prediction scenario shown in FIG. 1C as an example, the best beam of each of the M short periods in the (N+1) long period is predicted based on the beam information of the previous N long periods, in which case the first set of reference signal resources can include the reference signal resources corresponding to the N long periods, and the second set of reference signal resources can include the reference signal resources corresponding to the M short periods in the (N+1) long period.

[0110] In the embodiments of the present disclosure, one time instance can be one period, which can be a short period, a long period, or other time units, and the present disclosure does not limit this.

[0111] In an example, the first configuration information directly includes identification information of the reference signal resources in the first set of reference signal resources and identification information of the reference signal resources in the second set of reference signal resources. In this way, the terminal can determine the first set of reference signal resources and the second set of reference signal resources based on the identification information.

[0112] In another example, the first configuration information can only include the first set of reference signal resources and a first ID, and the terminal determines the second set of reference signal resources based on the first ID. Because the previous configuration information includes the information of the second set of reference signal resources and the first ID, the terminal can determine the second set of reference signal resources based on the previous historical configuration information.

[0113] In the example embodiments, the first configuration information includes the value of M.

[0114] In some embodiments, the network device can configure the value of M in the first configuration information, and the network device can directly indicate the value of M to the terminal, and the terminal determines the beam information corresponding to the M time instances according to the value of M indicated by the network device.

[0115] In step S2102, the terminal determines the first beam information corresponding to the M time instances.

[0116] In some embodiments, the terminal can predict the beam information corresponding to the M time instances through an AI model, and for the convenience of description, the beam information corresponding to the M time instances is referred to as the first beam information.

[0117] In step S2103, the terminal sends a beam report to the network device.

[0118] In some embodiments, the network device receives a beam report sent by the terminal.

[0119] The beam report includes first beam information corresponding to M time instances, the first beam information including L1-RSRP of a first beam, and a time instance identifier corresponding to the first beam or the L1-RSRP. For ease of description, the time instance identifier corresponding to the first beam is referred to as a first time instance identifier, and the time instance identifier corresponding to any other beam except the first beam is referred to as a second time instance identifier.

[0120] In some embodiments, the first beam information can include an identifier of a beam corresponding to each of the M time instances, and L1-RSRP of the beam corresponding to each of the M time instances.

[0121] In some embodiments, each time instance can correspond to one or more beams, and the number of beams corresponding to each time instance included in the beam report can be the same or different.

[0122] In an exemplary embodiment, the number of beams corresponding to each of the M time instances included in the beam report is the same. For example, each time instance corresponds to 2 beams.

[0123] In an exemplary embodiment, the number of beams corresponding to each of the M time instances included in the beam report is different. For example, time instance A corresponds to 1 beam, and time instance B corresponds to 2 beams.

[0124] In an exemplary embodiment, when the number of beams corresponding to each of the M time instances included in the beam report is different, the beam report further includes a second time instance identifier corresponding to at least one other beam except the first beam.

[0125] The first beam can be a beam with the largest L1-RSRP among all beams corresponding to the M time instances. The L1-RSRP of the first beam included in the first beam information can be an absolute value of the L1-RSRP.

[0126] The following is described by taking M as 2 and each time instance corresponding to 2 beams as an example, but the value of M and the number of beams corresponding to each time instance are not limited by the present disclosure.

[0127] For example, the beam report contains beam information of the following multiple beams, each beam corresponding to a time instance, an identity of the beam, and information of an RSRP value as follows: time instance A corresponds to: beam 1, L1-RSRP#1 is -89 dBm; beam 2, L1-RSRP#2 is -86 dBm. Time instance B corresponds to: beam 3, L1-RSRP#3 is -87 dBm; beam 4, L1-RSRP#4 is -88 dBm.

[0128] Wherein, the L1-RSRP of beam 2 in time instance A is the largest, thus the first beam is beam 2, the L1-RSRP of the first beam is -86 dBm, and the first time instance identity corresponding to the first beam is A (or 1, i.e. the first time instance).

[0129] In the case of M being 2, the first time instance identity corresponding to the first beam needs 1 bit to indicate whether the time instance corresponding to the first beam is the first time instance or the second time instance.

[0130] It can be understood that in the case of M being 3-4, 2 bits are needed to indicate which time instance the time instance corresponding to the first beam is.

[0131] In the exemplary embodiment, the first beam information further includes an identity of the first beam, which includes at least one of a reference signal resource identity (RS ID), a beam identity (beam ID), and a TCI state identity (TCI state ID).

[0132] In the embodiment of the present disclosure, the first beam information reported by the terminal to the network device includes the L1-RSRP of the first beam, the first time instance identity corresponding to the first beam or the L1-RSRP, and the identity of the first beam, so that the network device can determine the first beam and the quality information of the first beam.

[0133] Optionally, the first beam information reported by the terminal to the network device includes the L1-RSRP of the first beam, and the first time instance identifier corresponding to the first beam or the L1-RSRP, and the identifier of the first beam. Since the second reference signal resource set can be the same in different time instances, and the beam identifier reported by the terminal for each time instance is the RS ID corresponding to one or more reference signal resource sets determined from the second reference signal resource set, the beam identifier reported for each time instance can be the same, so the first time instance identifier corresponding to the strongest L1-RSRP or the first time instance identifier corresponding to the beam identifier of the strongest L1-RSRP must be indicated. If the beam identifier reported by the terminal for each time instance is different, and the network device also knows the correspondence between the beam identifier and the time instance, the terminal can not report the first time instance identifier corresponding to the strongest L1-RSRP.

[0134] In an example embodiment, the first beam information further includes a first bitmap, and the first bitmap includes one of the following:

[0135] M bits, wherein each bit indicates whether the beam information corresponding to each of the M time instances is included in the beam report;

[0136] M-1 bits, wherein each bit indicates whether the beam information corresponding to each of the M-1 time instances except the first time instance is included in the beam report.

[0137] In an example, the first bitmap includes M bits, and the M bits correspond to the M time instances one by one, and each bit is used to indicate whether the beam information corresponding to the time instance corresponding to the bit is included in the beam report. For example, a bit value of '1' indicates that the beam information of the time instance corresponding to the bit is included in the beam report, otherwise it indicates that the beam information of the time instance corresponding to the bit is the same as that of the previous time instance. For example, M=4, and the first bitmap is 1101, indicating that the beam information corresponding to the first time instance, the third time instance and the fourth time instance is included in the beam report.

[0138] In another example, the first bitmap includes M-1 bits, and the M-1 bits correspond to M-1 time instances except the first time instance one by one, and each bit is used to indicate whether the beam information corresponding to the time instance corresponding to the bit is included in the beam report, because it can be considered that the first time instance must be reported, so 1 bit can be omitted. For example, M=4, and the first bitmap is 101, indicating that the beam information corresponding to the first time instance, the third time instance and the fourth time instance is included in the beam report.

[0139] In the embodiments of the present disclosure, the first bitmap can be located at the front of the beam report, or the first bitmap can be located before the first time instance identifier corresponding to the first beam or the L1-RSRP, or the first bitmap can also be located at other positions.

[0140] In the example embodiments, the first time instance identifier indicates the sequence number of the time instance corresponding to the L1-RSRP in the time instances included in the beam report.

[0141] In the embodiments of the present disclosure, in the beam report, in the case that the first bitmap is located before the first time instance identifier corresponding to the L1-RSRP, the first time instance identifier can indicate the sequence number of the time instance corresponding to the L1-RSRP in the time instances included in the beam report.

[0142] That is, if the first bitmap is at the front of the beam report, or before the first time instance identifier corresponding to the first beam or the L1-RSRP, the first time instance identifier can also only indicate the first one of the time instances containing beam information in the beam report.

[0143] For example, M=4, that is, a total of 4 time instances, the first bitmap is 0101 (or 010), that is, the first bitmap indicates that only the beam information of the first time instance and the third time instance is contained in the beam report, then the first time instance identifier corresponding to the strongest L1-RSRP can only indicate whether it is the first time instance or the third time instance (that is, only 1 bit is needed), and does not need to indicate which one of the 4 time instances (2 bits are not needed).

[0144] In the example embodiments, the first beam information further includes: second beam information of a second beam, the second beam being other than the first beam in the first time instance, the first time instance being the time instance corresponding to the first beam; and second beam information of each beam in a second time instance, the second time instance being other than the first time instance; wherein the second beam information includes an identifier of the beam and a differential L1-RSRP.

[0145] That is, the M time instances include the first time instance and the second time instance, the beams corresponding to the first time instance include the first beam and the second beam, wherein the first beam is the strongest beam among all the beams corresponding to the M time instances, and the second beam is other than the strongest beam in the first time instance.

[0146] The second beam information of each second beam in the first time instance can include an identity of the second beam and a differential L1-RSRP of the second beam, and the second beam information of each beam in the second time instance can include an identity of each beam in the second time instance and a differential L1-RSRP of each beam in the second time instance.

[0147] The identity of the beam included in the second beam information can be at least one of an RS ID, a beam ID, and a TCI state ID, and the differential L1-RSRP of the beam refers to a difference between the L1-RSRP of the beam and the L1-RSRP of the first beam, i.e., how much smaller the L1-RSRP of the beam is than the L1-RSRP of the first beam.

[0148] In an example embodiment, the first beam information includes at least one of the following: a first bitmap; an identity of a first time instance; an identity of the first beam; an identity of a second beam; an identity of each beam corresponding to a second time instance; an L1-RSRP; a differential L1-RSRP of the second beam; and a differential L1-RSRP of each beam corresponding to the second time instance.

[0149] The order of the at least one included in the first beam information in the beam report includes at least one of the following:

[0150] The first bitmap is at the front;

[0151] The identity of the first time instance corresponding to the first beam is at the front;

[0152] The identity of the first time instance corresponding to the first beam is after the first bitmap;

[0153] The identity of the first beam is after the identity of the first time instance corresponding to the first beam;

[0154] The identity of the first beam is before the identities of all other beams;

[0155] The identity of the second beam is before the identities of each beam corresponding to the second time instance;

[0156] The identity of the second beam is before the identities of each beam corresponding to a first type of second time instance, wherein the first type of second time instance is after the first time instance;

[0157] The identity of the second beam is after the identities of each beam corresponding to a second type of second time instance, wherein the second type of second time instance is before the first time instance;

[0158] The L1-RSRP is after the identities of all beams;

[0159] The L1-RSRP is before all differential L1-RSRPs;

[0160] The differential L1-RSRP is arranged in the order of the identification of the beam corresponding to the differential L1-RSRP.

[0161] The order of the contents included in the first beam information in the beam report is exemplified below, but the present disclosure is not limited thereto.

[0162] In an example, the identification of the first beam is in the front, the identification of the second beam (i.e., the beam other than the first beam in the first time instance) is after the identification of the first beam, the identification of the respective beams corresponding to the second time instance (i.e., the time instance other than the first time instance) is after the identification of the second beam, the identification of the respective beams corresponding to the second time instance is arranged in the order of the time instance (i.e., the identification of the respective beams corresponding to the first time instance in the second time instance is in the front, then the identification of the respective beams corresponding to the second time instance in the second time instance, and so on), the L1-RSRP of the first beam is after the identification of all the beams, the differential L1-RSRP of the second beam is after the L1-RSRP of the first beam and arranged in the order of the identification of the second beam, and the differential L1-RSRP of the respective beams corresponding to the second time instance is after the differential L1-RSRP of the second beam and arranged in the order of the identification of the respective beams corresponding to the second time instance. Optionally, the first bitmap and the first time instance identification corresponding to the first beam are in the front, and whether the first bitmap is in the front or the first time instance identification corresponding to the second beam is in the front is not limited herein.

[0163] For example, the beam report contains the beam information of the following multiple beams, the information of the time instance corresponding to each beam, the identification of the beam and the RSRP value is as follows:

[0164] The time instance A corresponds to: beam 1, L1-RSRP #1 is -89 dBm; beam 2, L1-RSRP #2 is -86 dBm.

[0165] The time instance B corresponds to: beam 3, L1-RSRP #3 is -87 dBm; beam 4, L1-RSRP #4 is -88 dBm.

[0166] The time instance C corresponds to: beam 2, L1-RSRP #5 is -88 dBm; beam 5, L1-RSRP #6 is -90 dBm.

[0167] In this case, the content included in the first beam information, in addition to the first bitmap and the identification of the time instance A (the first time instance corresponding to the first beam), can be the identification of the beam 2, the identification of the beam 1, the identification of the beam 3, the identification of the beam 4, the identification of the beam 2, the identification of the beam 5, L1-RSRP #2, differential L1-RSRP #1, differential L1-RSRP #3, differential L1-RSRP #4, differential L1-RSRP #5, and differential L1-RSRP #6 in the order of the beam report. The first bitmap and the identification of the time instance A can be in the front or the identification of the time instance A can be in the front.

[0168] In another example, the number of beams included in each time instance is different, and in addition to the identification of the first beam, 1 bit is required before the identification of each other beam to indicate whether the time instance corresponding to the identification of the beam is the same as or different from the time instance of the previous beam, or the number of bits required is the same as the number of bits required for the identification of the time instance corresponding to the first beam, that is, directly indicating the identification of the time instance corresponding to each other beam.

[0169] In this case, the content included in the first beam information, in addition to the first bitmap, the identification of the time instance, the identification of the beam, and L1-RSRP in the order of the beam report can be the identification of the first time instance corresponding to the first beam, the identification of the first beam, the identification of the first time instance corresponding to the second beam and the identification of the second beam, the identification of the second time instance corresponding to each beam of the second time instance, the identification of each beam corresponding to the second time instance (the identification of each beam corresponding to the second time instance is arranged in the order of the time instance (that is, the identification of each beam corresponding to the first time instance in the second time instance is arranged first, followed by the identification of each beam corresponding to the second time instance in the second time instance, and so on)), the L1-RSRP of the first beam, the differential L1-RSRP of the second beam (arranged in the order of the identification of the second beam), the differential L1-RSRP of each beam corresponding to the second time instance (arranged in the order of the identification of each beam corresponding to the second time instance). The first bitmap can be before the identification of the first time instance corresponding to the first beam or after the identification of the first time instance corresponding to the first beam, which is not limited here.

[0170] For example, the beam report contains beam information of the following multiple beams, the time instance corresponding to each beam, the identification of the beam, and the information of the RSRP value as follows:

[0171] The time instance A corresponds to: the beam 1, the L1-RSRP #1 is -89 dBm; the beam 2, the L1-RSRP #2 is -86 dBm; and the beam 3, the L1-RSRP #3 is -87 dBm.

[0172] Time instance B corresponds: beam 4, L1-RSRP#4 is -88dBm.

[0173] Time instance C corresponds: beam 2, L1-RSRP#5 is -88dBm; beam 5, L1-RSRP#6 is -90dBm.

[0174] In this case, in addition to the first bitmap, the contents included in the first beam information can be: the identification of time instance A, the identification of beam 2, the identification of time instance A (or a bit value indicating the same time instance as the previous beam), the identification of beam 1, the identification of time instance A (or a bit value indicating the same time instance as the previous beam), the identification of beam 3, the identification of time instance B (or a bit value indicating a different time instance from the previous beam), the identification of beam 4, the identification of time instance C (or a bit value indicating a different time instance from the previous beam), the identification of beam 2, the identification of time instance C (or a bit value indicating the same time instance as the previous beam), the identification of beam 5, L1-RSRP#2, differential L1-RSRP#1, differential L1-RSRP#3, differential L1-RSRP#4, differential L1-RSRP#5, and differential L1-RSRP#6 in the beam report. The first bitmap can be before or after the identification of the first time instance corresponding to the first beam, which is not limited here.

[0175] In another example, the identification of the time instance corresponding to the first beam is at the front of the beam report, the position of the first bitmap is not limited, or the first bitmap can not be included in the beam report, and the order of the remaining contents is the same as the above example.

[0176] In another example, the front and rear positions of the first time instance corresponding to the first bitmap and the first beam are not limited, and the order of the identification of the beam is mainly clarified. The identification of the first beam is at the front of the identification of the corresponding beam at all time instances; then, the M time instances can be divided into time instances before the first time instance and time instances after the first time instance, wherein the time instances before the first time instance are referred to as second time instances of a first type, and the time instances after the first time instance are referred to as second time instances of a second type; the respective beam identifications corresponding to the second time instances of the first type are after the identification of the first beam, the respective beam identifications corresponding to the second time instances of the first type are after the identification of the second beam (i.e., the beam other than the first beam in the first time instance), and the respective beam identifications corresponding to the second time instances of the second type are after the identification of the second beam. Next, the L1-RSRP corresponding to each beam is in the same order as the identification of the beam. That is, the L1-RSRP of the first beam is after the identification of all beams, the differential L1-RSRP of the respective beams corresponding to the second time instances of the first type is after the L1-RSRP of the first beam and is arranged in the order of the identification of the respective beams corresponding to the second time instances of the first type, the differential L1-RSRP of the second beam is after the differential L1-RSRP of the respective beams corresponding to the second time instances of the first type and is arranged in the order of the identification of the second beam, and the differential L1-RSRP of the respective beams corresponding to the second time instances of the second type is after the differential L1-RSRP of the second beam and is arranged in the order of the identification of the respective beams corresponding to the second time instances of the second type.

[0177] For example, the beam report contains beam information of the following multiple beams, the time instance corresponding to each beam, the identification of the beam, and the information of the RSRP value as follows:

[0178] The time instance A corresponds to: beam 1, L1-RSRP#1 is -89 dBm; beam 2, L1-RSRP#2 is -86 dBm.

[0179] The time instance B corresponds to: beam 3, L1-RSRP#3 is -87 dBm; beam 4, L1-RSRP#4 is -85 dBm.

[0180] The time instance C corresponds to: beam 2, L1-RSRP#5 is -88 dBm; beam 5, L1-RSRP#6 is -90 dBm.

[0181] In this case, the content included in the first beam information, in addition to the first bitmap and the identification of the time instance B (the first time instance corresponding to the first beam), can be the identification of the beam and the order of L1-RSRP in the beam report: the identification of beam 4, the identification of beam 1, the identification of beam 2, the identification of beam 3, the identification of beam 2, the identification of beam 5, L1-RSRP #4, differential L1-RSRP #1, differential L1-RSRP #2, differential L1-RSRP #3, differential L1-RSRP #5, differential L1-RSRP #6. Wherein the first bitmap can be before the identification of the first time instance corresponding to the first beam, or after the identification of the first time instance corresponding to the first beam, which is not limited here.

[0182] In another example, the number of beams included in each time instance is different, then 1 bit is required before the identification of the beam of the other beam except the first beam, to indicate whether the time instance corresponding to the identification of the beam is the same as or different from the time instance of the previous beam, or the number of bits required is the same as the number of bits required for the identification of the time instance corresponding to the first beam, that is, directly indicating the identification of the time instance corresponding to each other beam.

[0183] In this case, the content included in the first beam information, in addition to the first bitmap, the identification of the time instance, the identification of the beam and L1-RSRP, can be in the order of the beam report: the identification of the first beam corresponding to the first time instance, the identification of the first beam, the second time instance identification of each beam corresponding to the second time instance of the first type and the identification of each beam, the identification of each beam corresponding to the second time instance of the second type, the differential L1-RSRP of each beam corresponding to the second time instance of the first type, the differential L1-RSRP of each beam corresponding to the second time instance of the second type. Wherein the first bitmap can be before the identification of the first time instance corresponding to the first beam, or after the identification of the first time instance corresponding to the first beam, which is not limited here.

[0184] For example, the beam report contains beam information of the following multiple beams, the time instance corresponding to each beam, the identification of the beam and the information of the RSRP value are as follows:

[0185] The time instance A corresponds to: beam 1, L1-RSRP #1 is -89dBm; beam 2, L1-RSRP #2 is -86dBm; beam 3, L1-RSRP #3 is -87dBm.

[0186] The time instance B corresponds to: beam 4, L1-RSRP #4 is -85dBm.

[0187] The time instance C corresponds to: beam 2, L1-RSRP #5 is -88dBm; beam 5, L1-RSRP #6 is -90dBm.

[0188] In this case, in addition to the first bitmap, the order of the identification of the time instance, the identification of the beam and the L1-RSRP in the beam report in the first beam information can be: the identification of the time instance B, the identification of the beam 4, the identification of the time instance A (or a bit value indicating that the time instance is different from that of the previous beam), the identification of the beam 1, the identification of the time instance A (or a bit value indicating that the time instance is the same as that of the previous beam), the identification of the beam 2, the identification of the time instance A (or a bit value indicating that the time instance is the same as that of the previous beam), the identification of the beam 3, the identification of the time instance C (or a bit value indicating that the time instance is different from that of the previous beam), the identification of the beam 2, the identification of the time instance C (or a bit value indicating that the time instance is the same as that of the previous beam), the identification of the beam 5, L1-RSRP #4, differential L1-RSRP #1, differential L1-RSRP #2, differential L1-RSRP #3, differential L1-RSRP #5, and differential L1-RSRP #6.

[0189] The order of the content included in the first beam information in the beam report is exemplified below with M being 4 and the first beam being the strongest beam in the second time instance, but the present disclosure is not limited thereto.

[0191] In another example, in the beam report, the first bitmap is given first, such as indicating the beam information of the first time instance, the second time instance and the fourth time instance are all contained in the beam report; then the first time instance identifier is given, indicating that the beam with the strongest L1-RSRP (i.e. the first beam) is in the second time instance; then the beam identifier corresponding to the beam in the first time instance is given, then the beam identifier corresponding to the other beams (except the first beam) in the second time instance is given, then the beam identifier corresponding to the beam in the fourth time instance is given, and then the absolute value of the L1-RSRP corresponding to the first beam is given; then the differential L1-RSRP corresponding to each beam identifier in sequence is given.

[0241] The optional implementation of step S5102 can refer to the optional implementation of step S2103 in FIG. 2 and other associated parts in the embodiments involved in FIG. 2, which will not be repeated here.

[0242] In some embodiments, the above method can include the method of the above-mentioned embodiments of the communication system side, the terminal side, the network device side, and the like, which will not be repeated here.

[0243] The embodiments of the present disclosure provide a beam reporting method for reporting beam quality information of multiple time instances, solving the reporting problem of beam quality information based on AI beam prediction.

[0244] In the embodiments of the present disclosure, a terminal determines beam information corresponding to M time instances, and sends a beam report to a network device, wherein the beam report contains the beam information corresponding to the M time instances, and the beam information includes an absolute value of an L1-RSRP and a time instance identifier corresponding to the absolute value, wherein M is a positive integer greater than 1.

[0245] In an example, for example, time instance A corresponds to: beam 1, L1-RSRP#1 is -89dBm; beam 2, L1-RSRP#2 is -86dBm. Time instance B corresponds to: beam 3, L1-RSRP#3 is -87dBm; beam 4, L1-RSRP#4 is -88dBm. Then, the absolute value of L1-RSRP is -86dBm corresponding to beam 2, and the time instance identifier corresponding to the absolute value is the first time instance. Since only two time instances are taken as an example, only 1 bit is needed to indicate whether it is the first time instance or the second time instance. If there are 3-4 time instances, 2 bits are needed to indicate which time instance it is.

[0246] Further, the beam information can also contain at least one of the absolute value corresponding RS ID, beam ID, and TCI state ID.

[0247] In the embodiments of the present disclosure, the beam information further includes a first bitmap, and the first bitmap contains M bits, each bit corresponding to one of the M time instances. The bit value of '1' indicates that the beam information of the time instance corresponding to the bit is contained in the beam report, otherwise it indicates that the beam information of the time instance corresponding to the bit is the same as that of the previous time instance.

[0248] Further, the first bitmap can have only M-1 bits, because the first time instance must be reported, and if the following time instance is the same as the one reported next to it, it does not need to be reported.

[0249] If the first bitmap is at the front of the beam report, i.e., before the time instance identifier corresponding to the absolute value, the time instance identifier can also only indicate the first one of the time instances containing beam information in the beam report.

[0250] For example, there are 4 time instances in total, and the first bitmap indicates that only the beam information of the first and third time instances is contained in the beam report. The time instance identifier corresponding to the absolute value only needs to indicate whether it is the first time instance or the third time instance (i.e., only 1 bit is needed), and does not need to indicate which one of the 4 time instances it is (2 bits are not needed).

[0251] In the embodiments of the present disclosure, after the absolute value of L1-RSRP, the beam information (identifier and differential RSRP) of other beams in the same time instance as the absolute value is reported first, and then the beam information (identifier and differential RSRP) of beams in other time instances is reported in the order of time instances.

[0252] The identifier can be at least one of an RS ID, a beam ID, and a TCI state ID.

[0253] The differential RSRP, i.e., Differential L1-RSRP, is the difference of the L1-RSRP of the beam relative to the absolute value, i.e., how many dB less than the absolute value.

[0254] In the embodiments of the present disclosure, the identifiers of the above-mentioned beams can be reported first, and then the L1-RSRP corresponding to each beam, but the order is the same. That is, the corresponding beam identifier is also given first, the beam identifier corresponding to other beams in the time instance where the absolute value is located is given, and then the identifiers of the beams corresponding to each time instance are given in the order of time instances. The order of the L1-RSRP is also given first, the differential L1-RSRP corresponding to each of the above-mentioned beam identifiers is given, and then the L1-RSRP corresponding to each beam identifier is given.

[0255] In an example, there are 4 time instances in total, and the beam report can be as shown in Table 1, where:

[0256] The first bitmap is given first, which indicates that the beam information of the first time instance, the second time instance, and the fourth time instance is contained in the beam report.

[0257] The time instance identifier is then given, which indicates that the L1-RSRP is strongest in the second time instance.

[0258] The beam identifier corresponding to the beam with the strongest L1-RSRP is then given.

[0259] The beam identifiers corresponding to other beams in the second time instance are then given.

[0260] Then the beam identity corresponding to the beam in the first time instance is given;

[0261] Then the beam identity corresponding to the beam in the fourth time instance is given;

[0262] Then the absolute value of L1-RSRP corresponding to the strongest beam is given;

[0263] Then the differential L1-RSRP corresponding to each of the other beam identities is given in order.

[0264] Table 1

[0265] In another example, after the absolute value of L1-RSRP, the beam information (identity and differential RSRP) of the beams of the other time instances is reported in order of time instance. That is, the difference from the above example is that the beam information (identity and differential RSRP) of the other beams of the same time instance as the absolute value is not reported first.

[0266] In this example, there are a total of 4 time instances, and the beam report can be as shown in Table 2, wherein:

[0267] First, the first bitmap is given, indicating that the beam information of the first time instance, the second time instance and the fourth time instance are all included in the beam report;

[0268] Then the time instance indication identity is given: indicating that the L1-RSRP is strongest in the second time instance;

[0269] Then the beam identity corresponding to the beam with the strongest L1-RSRP is given;

[0270] Then the beam identity corresponding to the beam in the first time instance is given;

[0271] Then the beam identity corresponding to the other beams (except the strongest beam) in the second time instance is given;

[0272] Then the beam identity corresponding to the beam in the fourth time instance is given;

[0273] Then the absolute value of L1-RSRP corresponding to the strongest beam is given;

[0274] Then the differential L1-RSRP corresponding to each of the other beam identities is given in order.

[0275] Table 2

[0276] In the embodiments of the present disclosure, if the number of reported beams corresponding to each time instance is fixed, the terminal and the network device can not indicate the time instance identifier corresponding to other beams. However, if the number of reported beams corresponding to each time instance is not fixed, at least 1 bit is needed to indicate whether the time instance corresponding to the beam is the same as the previous one before the beam starts to report.

[0277] In the embodiments of the present disclosure, the terminal receives the first configuration information, determines the first reference signal resource set and the second reference signal resource set according to the first configuration information, the first reference signal resource set includes reference signal resources for measuring L1-RSRP / L1-SINR, and the second reference signal resource set includes a reference signal resource set corresponding to the beam information output by the model, the input of the model being L1-RSRP / L1-SINR corresponding to the first reference signal resource set. The terminal reports the beam information corresponding to the second reference signal resource set.

[0278] In an example, the first configuration information directly includes reference signal resource identifier information included in the first reference signal resource set and the second reference signal resource set.

[0279] In another example, the first configuration information only includes the first reference signal resource set and a first ID, and the terminal determines the second reference signal resource set based on the first ID. Because the previous configuration information includes the information of the second reference signal resource set and the first ID, the terminal determines the second reference signal resource set based on the previous historical configuration information.

[0280] In the embodiments of the present disclosure, M can also be determined directly based on the first configuration information, or the first ID in the first configuration information and historical configuration information.

[0281] In the embodiments of the present disclosure, the beam refers to beam, and the beam measurement refers to measuring L1-RSRP and / or L1-SINR of a reference signal including a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), and a sounding reference signal (SRS); the beam indication refers to an indication of a TCI state, wherein the TCI state contains at least one quasi Co-location (QCL) type (Type), QCL Type A, B, C, and D, wherein Type D is a reception parameter information, commonly known as a beam. Types A, B, and C include at least one of Doppler shift, Doppler spread, average delay, and delay spread related parameters. For the uplink beam, it refers to spatial relation information or spatial filter parameters.

[0282] In the embodiments of the present disclosure, M is also configured in the first configuration information.

[0283] In the embodiments of the present disclosure, the number of reported beams corresponding to each time instance is also configured by the network, and the number of reported beams corresponding to each time instance is the same.

[0284] The beam reporting method provided by the embodiments of the present disclosure includes the instance indication information of the strongest beam and the order of the beam information corresponding to each time instance in the beam report, so as to ensure that the base station can determine the beam information corresponding to each time instance based on the beam report.

[0285] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.

[0286] The embodiments of the present disclosure also propose an apparatus for implementing any of the above methods, for example, an apparatus including units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is proposed, including units or modules for implementing each step performed by a network device (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.
