Description

An information transmission method, apparatus and storage medium

[0001] This disclosure claims priority to Chinese Patent Application No. 202510119660.X, filed on January 24, 2025, entitled "An Information Transmission Method, Apparatus and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to an information transmission method, apparatus and storage medium. Background Technology

[0003] In New Radio (NR) systems, to combat path loss in high-frequency scenarios, the transmitter and receiver obtain matched beam pairs through beam management to improve beamforming gain. In existing downlink beam management procedures, the base station transmits reference signals in different downlink beam directions. The terminal uses its receiving beam to receive these reference signals, measures them, selects multiple reference signals whose reception performance meets preset conditions, and reports the indices of these reference signals and their corresponding reference signal received power (RSRP) to the base station. The base station selects a suitable beam for subsequent communication based on the information reported by the terminal and instructs the terminal on the selected beam.

[0004] In related technologies, to obtain the optimal beam pair, the base station needs to transmit reference signal resources on all downlink beams, resulting in significant consumption of these resources. Simultaneously, the terminal needs to measure the reference signals transmitted on all downlink beams using all receiving beams, incurring substantial measurement overhead. Therefore, artificial intelligence (AI) and machine learning (ML) are applied to beam management. In AI / ML-based beam management, the optimal beam can be predicted using measurements of a subset of beams or historical beam measurement results, thereby saving reference signal resources and measurement overhead.

[0005] To obtain the optimal beam, it is necessary to measure multiple predicted beams. However, due to the large number of possible combinations of optimal beams, existing methods are insufficient to measure all possible predicted optimal beams. Summary of the Invention

[0086] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0087] In the embodiments of this disclosure, the term "at least one" refers to one or more items, and "more than one" refers to two or more items. Other quantifiers are similar. For example, at least one of a, b, and c can be expressed as: a, b, c, ab, ac, bc, or abc, where a, b, and c can be a single item or multiple items.

[0088] The terms "first," "second," etc., used in the embodiments of this disclosure are for illustrative purposes and to distinguish the objects being described. They do not indicate any order or limit on the number of objects in the embodiments of this disclosure, and cannot constitute any limitation on the embodiments of this disclosure. For example, the use of terms such as "first reference signal resource," "second reference signal resource," and "third reference signal resource" is only to distinguish different reference signal resources, and does not indicate differences in the size, priority, or importance of these three reference signal resources.

[0089] To better understand the methods provided in the embodiments of this disclosure, the architecture of the communication system of the embodiments of this disclosure will be described first.

[0090] Figure 1 is a schematic diagram of an architecture of a communication system provided in an embodiment of this disclosure. As shown in Figure 1, it includes a network device 101 and a terminal 102.

[0091] It should be noted that the architecture of the communication system and the number of devices in the architecture described above are merely examples. For instance, the architecture may also include core network devices, and the number of network devices and terminals may be other values. This disclosure does not limit the architecture of the communication system or the number of devices in the architecture.

[0092] The technical solutions provided in this disclosure can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G NR systems and their evolved communication systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminals and network equipment. The systems may also include a core network component, such as an evolved packet core (EPC) or a 5G core network (5GC).

[0093] The network device involved in this disclosure can be a base station, which may include multiple cells providing services to terminals. Depending on the application, the base station may also be called an access point, or a device in the access network that communicates with wireless terminals through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in this disclosure can be an evolved Node B (eNB or e-NodeB) in an LTE system, a 5G base station (gNB) in a 5G network architecture (next generation system), or a home evolved node B (HeNB), relay node, femto, pico, network testing equipment, etc., and is not limited in this disclosure. In some network architectures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, which may also be geographically separated.

[0094] The terminal disclosed in this embodiment may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal may differ in different systems; for example, in a 5G or 6G system, the terminal may be called user equipment (UE). The wireless terminal may be a universal serial bus (USB) storage device, other personal computer memory devices, or a dongle. It may also communicate with one or more core networks (CNs) via a radio access network (RAN). The wireless terminal may be a mobile terminal, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) telephones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), Personal Computers, Tablet PCs, and Machine-Type Communication (MTC) terminals. Wireless terminals can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this disclosure.

[0095] In related technologies, to obtain the optimal beam pair, the base station needs to transmit reference signal resources on all downlink beams, which consumes a significant amount of reference signal resources. Simultaneously, the terminal needs to use all receive beams to measure the reference signals transmitted on each downlink beam, resulting in substantial measurement overhead. Therefore, AI / ML and similar technologies are applied to beam management.

[0096] AI / ML-based beam management use cases include spatial beam prediction and temporal beam prediction. Spatial beam prediction refers to predicting the top K beams in beam set A based on the measurement results of beam set B at a certain moment. Temporal beam prediction refers to predicting the top K beams in beam set A at multiple future moments or time periods based on beam set B measured at several historical moments. Beam set A and beam set B can both be sets composed of downlink transmission beams.

[0097] In AI / ML-based beam management, the AI / ML model can be deployed on either the network side or the terminal side. Regardless of whether the AI / ML model is deployed on the network side or the terminal side, to improve the accuracy of downlink transmission beam prediction or to enable the terminal to obtain the received beam information of the predicted beams, the base station can trigger the terminal to measure the predicted K optimal beams or a subset of the predicted K optimal beams, and report the measurement results. For the network-side model, the base station infers the K optimal beams in beam set A and can trigger the measurement of the predicted K optimal beams based on the inference results. For the terminal-side model, the terminal reports the inference results, i.e., reports the information of the predicted K optimal beams, to the base station. The base station can trigger the measurement of the K optimal beams or a subset of the predicted K optimal beams based on the received inference results. After the terminal reports the measurement results to the base station, the base station selects appropriate beams from the predicted K optimal beams for beam indication for downlink transmission.

[0098] Taking the deployment of an AI / ML model on the terminal side as an example, the AI / ML inference reporting and beam indication process is shown in Figure 2, including the following steps: 1. The base station sends a reference signal to the terminal through beam set B; 2. The terminal measures the reference signal corresponding to beam set B and obtains a first measurement result; 3. Based on the first measurement result, inference is performed through the AI / ML model to obtain an inference result, which includes information on the K optimal beams in the predicted beam set A; 4. The terminal reports the inference result to the base station; 5. The base station sends a reference signal to the terminal through the predicted K optimal beams, or sends a reference signal to the terminal through a portion of the predicted K optimal beams; 6. The terminal measures the corresponding reference signal and obtains a second measurement result; 7. The terminal feeds back the second measurement result to the base station; 8. The base station selects a suitable beam for subsequent communication based on the second measurement result and indicates the information of the selected beam to the terminal.

[0099] Steps 5 to 7 can use the existing aperiodic channel state information (CSI) reporting process, that is, the base station triggers an aperiodic CSI report based on the inference results fed back by the terminal, and the triggered aperiodic CSI report is associated with the reference signals corresponding to the K optimal beams or the reference signals corresponding to some of the K optimal beams.

[0100] In related technologies, aperiodic CSI reports are triggered via downlink control information (DCI). The base station can configure up to 128 trigger states (CSI-AperiodicTriggerState) for the terminal. Each trigger state is associated with one or more aperiodic CSI reports. The triggered aperiodic CSI report can be determined based on the trigger state indicated by the CSI request field in the DCI. The reference signal resources associated with the CSI report and the quasi-co-location information of the reference signals are configured via radio resource control (RRC) signaling. The maximum number of bits in the CSI request field is 6, meaning that the trigger state can be dynamically indicated across up to 64 trigger states via DCI signaling.

[0101] Assuming beam set A has 32 beams and K = 4, there are tens of thousands of possible optimal combinations of the K beams. Clearly, configuring the reference signal resources and corresponding trigger states for all possible optimal combinations of the K beams via RRC signaling, and then triggering the corresponding reference signal resources via DCI based on the inference results, cannot satisfy the measurement of all possible predicted optimal K beams.

[0102] To address the aforementioned technical problems, embodiments of this disclosure provide an information transmission method, apparatus, and storage medium. A terminal can determine the reference signal resource corresponding to any optimal beam combination from the configured reference signal resources based on first information sent by a network device. This enables the measurement of all possible predicted optimal beams, improving the performance of AI / ML-based beam management. The method and apparatus are based on the same application concept. Since the principles by which the method and apparatus solve the problems are similar, their implementations can be mutually referenced, and repeated details will not be elaborated further.

[0103] It should be noted that, in this embodiment of the disclosure, measuring the beam is equivalent to measuring the reference signal transmitted on the beam, and measuring the reference signal resource is equivalent to measuring the reference signal transmitted on the reference signal resource. There is a correspondence between the beam and the reference signal resource. In some embodiments, the measurement resource mentioned in this embodiment of the disclosure may also be referred to as the measurement reference signal resource or the reference signal resource.

[0104] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0105] Figure 3 is a flowchart of an information transmission method provided in an embodiment of this disclosure. As shown in Figure 3, the method includes:

[0106] S301. The network device sends first information to the terminal. The first information is used to indicate at least one of the following: M groups of first reference signal resources, M groups of quasi-co-location information, L numbers of reference signal resources, and N CSI reports.

[0107] In other words, the terminal receives the first information sent by the network device.

[0108] M, L, and N are positive integers.

[0109] The first reference signal resource in group M is the reference signal resource to be measured.

[0110] The M-group quasi-co-location information refers to the quasi-co-location information corresponding to the M-group reference signal resources to be measured.

[0111] In one possible implementation, each quasi-co-location information in the M groups includes at least one of the following: a transmission configuration indication (TCI) status index, a reference signal resource index, and a quasi-co-location type.

[0112] The reference signal resource index indicates a reference signal resource, or indicates a reference signal that is quasi-co-located with the corresponding reference signal resource.

[0113] The number of each of the L reference signal resources is the number of reference signal resources in a set to be measured. L is less than or equal to M.

[0114] N CSI reports correspond to the same trigger state, and the N CSI reports are a subset of the CSI reports associated with the trigger state.

[0115] For example, trigger state 1 is associated with CSI report 1, CSI report 2, and CSI report 3, and the first information can be used to indicate CSI report 1 and CSI report 2.

[0116] Network devices can determine primary information based on the inference results of AI / ML.

[0117] The relationship between First Information and CSI Reports is explained in detail below.

[0118] 1. The first information is the indication information related to M CSI reports, and the first CSI report is the report in the M CSI reports.

[0119] When the first information indicates at least one of the following: M groups of first reference signal resources, M groups of quasi-co-location information, and L numbers of reference signal resources, the first information is indication information related to M CSI reports.

[0120] The first reference signal resource in group M consists of the reference signal resources of M CSI reports. The quasi-co-location information in group M consists of the quasi-co-location information of the measurement resources corresponding to the M CSI reports. The number of reference signal resources L is the number of reference signal resources corresponding to the L CSI reports in the M CSI reports.

[0121] 2. The first information is the instruction information related to the M reports of the first CSI report.

[0122] When the first information indicates at least one of the following: M groups of first reference signal resources, M groups of quasi-co-location information, and L numbers of reference signal resources, the first information is indication information related to the M reports of the first CSI report.

[0123] The first reference signal resources in group M are the reference signal resources required for measurement in the M reports of the first CSI report. The quasi-co-location information in group M is the quasi-co-location information of the measurement resources corresponding to the M reports of the first CSI report. The number of reference signal resources in group L is the number of reference signal resources required for measurement in the L reports of the first CSI report.

[0124] 3. The first information is indication information related to the M measurements reported in the first CSI report.

[0125] When the first information indicates at least one of the following: M groups of first reference signal resources, M groups of quasi-co-location information, and L numbers of reference signal resources, the first information is indication information related to the M measurements reported by the first CSI.

[0126] The M groups of first reference signal resources are the reference signal resources corresponding to the M measurements reported in the first CSI report. The M groups of quasi-co-location information are the quasi-co-location information of the measurement resources corresponding to the M measurements reported in the first CSI report. The L numbers of reference signal resources are the number of reference signal resources corresponding to the L measurements reported in the first CSI report.

[0127] S302. The terminal sends a first CSI report to the network device based on the first information.

[0128] In other words, the network device receives the first CSI report sent by the terminal.

[0129] In one possible implementation, the first CSI report may be determined based on M groups of second reference signal resources, which are determined based on at least one of M groups of first reference signal resources, M groups of quasi-co-location information, and L numbers of reference signal resources. Any group of reference signal resources in the M groups of second reference signal resources is a part of a third set of reference signal resources, which is the set of reference signal resources associated with the first CSI report.

[0130] The third set of reference signal resources is configured by the network device for the terminal.

[0131] The first information can directly indicate the M group of second reference signal resources, or it can indirectly indicate the M group of second reference signal resources. Below, we will explain in detail how the terminal determines the M group of second reference signal resources based on different first information scenarios, using the following five examples.

[0132] Case 1: The first information is used to indicate the first reference signal resource of group M.

[0133] In this case, the first set of M reference signal resources is the same as the second set of M reference signal resources, that is, any set of reference signal resources in the first set of M reference signal resources is a part of the third set of reference signal resources.

[0134] The relationship between the first reference signal resource of group M and the CSI report is explained in detail below.

[0135] (1.1) The first reference signal resource of group M is the measurement resource of M CSI reports, and the first CSI report is the report in group M CSI reports.

[0136] For example, each inference iteration yields the optimal beam at M time points (or M time intervals). The measurement report for the optimal beam at each time point (or time interval) is configured as one aperiodic CSI report, and the measurement report for the optimal beam at the M time points (or M time intervals) is configured as M aperiodic CSI reports. The network device can indicate the measurement resources for the M CSI reports based on the inference results.

[0137] The base station can configure a third reference signal resource set for each aperiodic CSI report, where the first reference signal resource group corresponding to the aperiodic CSI report is a subset of the third reference signal resource set; alternatively, the base station can configure a third reference signal resource set for M aperiodic CSI reports, where the M first reference signal resources are subsets of the third reference signal resource set. The base station can also configure corresponding quasi-co-location information for each third reference signal resource. The terminal can measure the M first reference signal resources respectively, obtain M aperiodic CSI reports, and report them.

[0138] (1.2) The first reference signal resource of group M is the reference signal resource required for the measurement of the M reports of the first CSI report.

[0139] For example, each inference yields the optimal beam at M time points (or M time periods). The measurement results of the optimal beam at each of the M time points (or M time periods) are reported at the M reporting times in the first CSI report. The network device can indicate the reference signal resources corresponding to the M reporting times based on the inference results.

[0140] The base station can configure a third set of reference signal resources for the first CSI report, and each set of first reference signal resources is a subset of this third set of reference signal resources; the base station can also configure corresponding quasi-co-location information for each third reference signal resource. The terminal can report a first CSI report once for each set of first reference signal resources measured.

[0141] (1.3) The first reference signal resources of the M groups are the reference signal resources corresponding to the M measurements reported by the first CSI. The time interval of each group of first reference signal resources can be configured by the network device.

[0142] For example, each inference yields the optimal beam at M time points (or M time periods). The measurement results of the optimal beam at the M time points (or M time periods) are reported at the first reporting time of the first CSI report. The time domain interval of the reference signal resources corresponding to the optimal beam at the M time points (or M time periods) can be configured by the network device.

[0143] The base station can configure a third reference signal resource set for the first CSI report, and each first reference signal resource group is a subset of this third reference signal resource set; the base station can also configure corresponding quasi-co-location information for each third reference signal resource. The terminal can measure M groups of first reference signal resources respectively, and report the M measurement results at one reporting time in the first CSI report.

[0144] The following details how the first information indicates the first reference signal resource of group M.

[0145] In one possible implementation, the third reference signal resource set includes multiple reference signal resources, and the first information includes indication information of M groups of first reference signal resources. For any one of the M groups of first reference signal resources, the indication information of the first reference signal resource group includes a bit corresponding to each reference signal resource, and the value of the bit is a first value or a second value. The first reference signal resource group includes: a reference signal resource in the third reference signal resource set whose corresponding bit has the first value.

[0146] For ease of understanding, the following is an example of the first information indicating the first reference signal resource of group M.

[0147] Example 1

[0148] CSI Report 1 and CSI Report 2 are aperiodic CSI reports. The first information is Media Access Control (MAC) Control Element (CE) signaling or DCI signaling, indicating the first reference signal resources in CSI Report 1 and CSI Report 2. Both CSI Report 1 and CSI Report 2 are associated with 8 reference signal resources. Assuming the first information is MAC-CE signaling, as shown in Figure 4, P1 to P8 are used to indicate which of the 8 reference signal resources in CSI Report 1 is the first reference signal resource, and P9 to P... 16 Used to indicate which of the eight reference signal resources in CSI Report 2 is the first reference signal resource. Among P1 to P8, if P... i =1, which means that the i-th reference signal resource among the 8 reference signal resources associated with CSI report 1 is the first reference signal resource; P9~P 16 In the middle, if P i =1, which means that the (i-8)th reference signal resource among the 8 reference signal resources associated with CSI report 2 is the first reference signal resource.

[0149] Example 2

[0150] CSI Report 1 is a semi-persistent report, associated with 8 reference signal resources. The first information is MAC-CE signaling, as shown in Figure 5. The first information includes 16 bits (P1~P2). 16 This is used to indicate the first reference signal resource corresponding to the two CSI report submissions. As shown in Figure 6, the base station sends first information related to CSI report 1 at time n1, triggers CSI report 1 at time n2, and the terminal determines the first reference signal resource corresponding to CSI report 1 submitted at time n3 based on P1 to P8 in the first information at time n1, and determines the first reference signal resource based on P9 to P8 in the first information at time n3. 16 Determine the first reference signal resource corresponding to CSI report 1 reported at time n4. Among P1 to P8, if P... i =1, which means that the i-th reference signal resource among the 8 reference signal resources associated with CSI report 1 is the first reference signal resource; P9~P 16 In the middle, if P i =1, which means that the (i-8)th reference signal resource among the 8 reference signal resources associated with CSI report 1 is the first reference signal resource.

[0151] Example 3

[0152] The base station is configured to report CSI report 1 aperiodically, associated with 8 reference signal resources, and the reported content is the measurement results of 2 sets of resources. The first information is MAC-CE signaling, as shown in Figure 5. The first information includes 16 bits (P1~P... 16 This is used to indicate the first reference signal resources corresponding to two measurements in the CSI report. The time-domain interval between the first set of reference signal resources and the CSI report trigger signaling, as well as the time-domain interval between the first set of reference signal resources and the second set of reference signal resources, are configured by the base station. As shown in Figure 7, the first set of first reference signal resources is determined based on P1 to P8 in the first information at time n1, and based on P9 to P... 16 Determine the first reference signal resources of the second group, and determine the content of the CSI report to be reported at time n3 based on the measurement results of the two groups of first reference signal resources.

[0153] Case 2: The first information is used to indicate the quasi-co-address information of group M.

[0154] In this case, the network device configures some information of the third reference signal resource for the terminal, such as time domain information and / or frequency domain information; the terminal can determine the M group of second reference signal resources based on the M group of quasi-co-address information.

[0155] In one possible implementation, the reference signal resources in each second reference signal resource group are determined from the third reference signal resource set based on any one of the following conditions: the configuration order of the reference signal resources, the ascending order of resource indices, the descending order of resource indices, and the time-domain information of the reference signal resources. The time-domain information of the reference signal resources may refer to the time-domain location of the reference signal resources.

[0156] The following section details the relationship between the M-group quasi-co-location information and the CSI report.

[0157] (2.1) The M groups of quasi-co-location information are the quasi-co-location information of the measurement resources corresponding to the M CSI reports, and the first CSI report is the report in the M CSI reports.

[0158] The base station can configure a third reference signal resource set for each CSI report (the configuration information includes time domain information and frequency domain information). The terminal can determine the first X reference signal resources or the last X reference signal resources in the third reference signal resource set as the second reference signal resource corresponding to the CSI report based on the number X of quasi-co-location information in the quasi-co-location information group corresponding to the CSI report and the configuration order of the reference signal resources.

[0159] The base station can configure a third reference signal resource set for each CSI report. The terminal can determine the X reference signal resources with the smallest resource index or the X reference signal resources with the largest resource index in the third reference signal resource set as the second reference signal resources corresponding to the CSI report, based on the number X of quasi-co-location information in the quasi-co-location information group corresponding to the CSI report and the resource index in ascending order, or based on the number X of quasi-co-location information in the quasi-co-location information group corresponding to the CSI report and the resource index in descending order.

[0160] The base station can configure a third reference signal resource set for each CSI report. The terminal can determine the reference signal resources in the third reference signal resource set that are in the first X times in the time domain or the last X times in the time domain as the second reference signal resource corresponding to the CSI report, based on the number X of quasi-co-location information in the quasi-co-location information group corresponding to the CSI report and the time domain information of the reference signal resources.

[0161] (2.2) The M-group quasi-co-location information is the quasi-co-location information of the measurement resources corresponding to the M reports of the first CSI report.

[0162] The base station can configure a third reference signal resource set for the first CSI report, and the terminal can determine M groups of second reference signal resources in the third reference signal resource set in accordance with the method in 2.1.

[0163] (2.3) The M-group quasi-co-location information is the quasi-co-location information of the measurement resources corresponding to the M measurements reported in the first CSI report.

[0164] The base station can configure a third reference signal resource set for the first CSI report, and the terminal can determine M groups of second reference signal resources in the third reference signal resource set in accordance with the method in 2.1.

[0165] Case 3: The first information is used to indicate the number of L reference signal resources.

[0166] In this case, the terminal can determine M groups of second reference signal resources based on the number of L reference signal resources. M = L.

[0167] In one possible implementation, for any one of the M groups of second reference signal resources, the second reference signal resource group includes: the first Q reference signal resources or the last Q reference signal resources in the third reference signal resource set, where Q is the number of reference signal resources in the second reference signal resource group.

[0168] The first Q reference signal resources or the last Q reference signal resources are determined based on any one of the following: the configuration order of the reference signal resources in the third reference signal resource set, the order of the resource index from smallest to largest, the order of the resource index from largest to smallest, or the time domain information of the reference signal resources.

[0169] For example, the first Q reference signal resources can refer to the reference signal resources in the third reference signal set that are configured in the first Q order, or the Q reference signal resources with the smallest resource index, or the Q reference signal resources with the largest resource index, or the reference signal resources located in the first Q time domains. The last Q reference signal resources can refer to the reference signal resources in the third reference signal set that are configured in the last Q order, or the Q reference signal resources with the largest resource index, or the Q reference signal resources with the smallest resource index, or the reference signal resources located in the last Q time domains.

[0170] The following details the relationship between the number of M reference signal resources and the CSI report.

[0171] (3.1) The number of M reference signal resources is the number of reference signal resources corresponding to the M CSI reports, and the first CSI report is the report in the M CSI reports.

[0172] The base station can configure a third reference signal resource set for each CSI report. The terminal can determine the first Q reference signal resources or the last Q reference signal resources in the third reference signal resource set as the second reference signal resource corresponding to the CSI report, based on the number Q of reference signal resources corresponding to the CSI report and the configuration order of the reference signal resources.

[0173] The base station can configure a third reference signal resource set for each CSI report. The terminal can determine the Q reference signal resources with the smallest resource index or the Q reference signal resources with the largest resource index in the third reference signal resource set as the second reference signal resources corresponding to the CSI report, based on the number Q of reference signal resources corresponding to the CSI report and the resource index in ascending order, or based on the number Q of reference signal resources corresponding to the CSI report and the resource index in descending order.

[0174] The base station can configure a third reference signal resource set for each CSI report. The terminal can determine the first Q reference signal resources or the last Q reference signal resources in the third reference signal resource set as the second reference signal resource corresponding to the CSI report based on the number Q of reference signal resources corresponding to the CSI report and the time domain information of the reference signal resources.

[0175] (3.2) The number of M reference signal resources is the number of reference signal resources corresponding to the M reports in the first CSI report.

[0176] The base station can configure a third reference signal resource set for the first CSI report, and the terminal can determine M groups of second reference signal resources in the third reference signal resource set in accordance with the method in 3.1.

[0177] (3.3) The number of M reference signal resources is the number of reference signal resources corresponding to the M measurements reported in the first CSI.

[0178] The base station can configure a third reference signal resource set for the first CSI report, and the terminal can determine M groups of second reference signal resources in the third reference signal resource set by referring to the method in 3.1.

[0179] For example, CSI Report 1 and CSI Report 2 are aperiodic reports. Both CSI Report 1 and CSI Report 2 are associated with 8 reference signal resources. The configuration information of the 8 reference signal resources includes frequency domain and time domain information. The first information is MAC-CE signaling, as shown in Figure 8. X1 to X3 are used to indicate the number Q1 of the second reference signal resources among the 8 reference signal resources in CSI Report 1, and X4 to X6 are used to indicate the number Q2 of the second reference signal resources among the 8 reference signal resources in CSI Report 2. The second reference signal resources of CSI Report 1 are the reference signal resources with a time domain position in the first Q1 of the reference signal resources associated with CSI Report 1; the second reference signal resources of CSI Report 2 are the reference signal resources with a time domain position in the first Q2 of the reference signal resources associated with CSI Report 2.

[0180] Case 4: The first information is used to indicate the first reference signal resource of group M and the quasi-co-address information corresponding to the first reference signal resource of group M.

[0181] In this case, the network device configures the terminal with some information of the third reference signal resource, such as time domain information and / or frequency domain information; the first reference signal resource of group M is the same as the second reference signal resource of group M.

[0182] The relationship between the first reference signal resource of group M and the CSI report can be found in the corresponding description in case 1, and will not be repeated here.

[0183] For example, CSI Report 1 and CSI Report 2 are aperiodic reports. Both CSI Report 1 and CSI Report 2 are associated with 8 reference signal resources. The configuration information of the 8 reference signal resources includes frequency domain and time domain information. The first information is MAC-CE signaling, as shown in Figure 9. P1 to P8 are used to indicate which of the 8 reference signal resources associated with CSI Report 1 are second reference signal resources, and P9 to P...16 Used to indicate which of the eight reference signal resources associated with CSI Report 2 are the second reference signal resources. Among P1 to P8, if P... i =1, which means that the i-th reference signal resource among the 8 reference signal resources associated with CSI report 1 is the second reference signal resource; P9~P 16 In the middle, if P i =1 indicates that the (i-8)th reference signal resource among the 8 reference signal resources associated with CSI report 2 is the second reference signal resource. TCI state 1, TCI state 2, ..., TCI state S are P1 to P1 respectively. 16 The quasi-co-address information for the resource indicated by the value 1.

[0184] Case 5: The first information is used to indicate the M groups of quasi-co-location information and the number of L reference signal resources.

[0185] In this scenario, the network device configures partial information about the third reference signal resource for the terminal, such as time-domain information and / or frequency-domain information; the terminal can determine the M groups of second reference signal resources based on the M groups of quasi-co-address information and the L number of reference signal resources. L is less than or equal to M.

[0186] When L equals M, the second reference signal resources of group M can be determined in the manner described in case 3.

[0187] For example, CSI Report 1 and CSI Report 2 are aperiodic reports. Both CSI Report 1 and CSI Report 2 are associated with 8 reference signal resources. The configuration information of the 8 reference signal resources includes frequency domain and time domain information. The first information is MAC-CE signaling, as shown in Figure 10. X1 to X3 are used to indicate the number Q1 of the second reference signal resources in the 8 reference signal resources in CSI Report 1, and X4 to X6 are used to indicate the number Q2 of the second reference signal resources in the 8 reference signal resources in CSI Report 2. The second reference signal resources in CSI Report 1 are the reference signal resources corresponding to the first Q1 indices of the reference signal resource resources associated with CSI Report 1, arranged in ascending order; the second reference signal resources in CSI Report 2 are the reference signal resources corresponding to the first Q2 indices of the reference signal resource resources associated with CSI Report 2, arranged in ascending order. TCI state 1, TCI state 2, ..., TCI state S are the quasi-co-address information corresponding to the second reference signal resources in CSI Report 1 and CSI Report 2.

[0188] When L is less than M, L = M-1. For the second reference signal resource group that indicates the number of reference signal resources, the second reference signal resources can be determined in the manner described in Case 3. The resource quantity of the remaining second reference signal resource group (the second reference signal resource group without an indicated number of reference signal resources) can be determined based on the total number of quasi-co-address information in the M groups of quasi-co-address information and the number of L reference signal resources, and then the second reference signal resources can be determined in the manner described in Case 3.

[0189] For example, the first information indicates a resource quantity of 4 for two sets of quasi-co-located information and one set of second reference signal resources. The total number of quasi-co-located information in the two sets is 10. The first information also indicates a resource quantity of 4 for one set of second reference signal resources. Therefore, the resource quantity of the other set of second reference signal resources is 10 - 4 = 6. Based on the resource quantity of each set of second reference signal resources, the second reference signal resources can be determined in the manner described in Case 3.

[0190] When L=1, the number of reference signal resources in each group is the same.

[0191] For example, if the first information indicates two sets of quasi-co-location information and one reference signal resource quantity of 6, it means that the resource quantity of both sets of second reference signal resources is 6, and the second reference signal resource of each set can be determined in the manner described in case 3.

[0192] The terminal can indicate the reference signal resources to be measured from the pre-configured reference signal resources based on the inference results of the AI / ML model, thereby enabling the network device to trigger the measurement of the optimal beam based on the inference results. The network device selects the beam for downlink transmission based on the reported CSI report, which improves the performance of AI / ML-based beam management.

[0193] In another possible implementation, the first CSI report can be a report from N CSI reports.

[0194] N CSI reports correspond to the same trigger state, and the N CSI reports are a subset of the CSI reports associated with the trigger state.

[0195] The first message indicates N CSI reports, which is equivalent to the first message activating N CSI reports.

[0196] The network device indicates N CSI reports via the first information. The terminal only needs to measure the reference signal resources corresponding to the N CSI reports to obtain the N CSI reports. When the network device indicates the trigger status corresponding to the N CSI reports via DCI, the terminal can report N CSI reports.

[0197] For example, the base station is configured with trigger state 1, which is associated with CSI report 1, CSI report 2, ..., CSI report 8. The base station sends first information, as shown in Figure 11. Here, P1 to P8 are used to indicate which of the eight CSI reports associated with trigger state 1 is the first CSI report. If P... i =1 indicates that the i-th CSI report among the 8 CSI reports associated with trigger state 1 is the first CSI report. If the base station indicates trigger state 1 in the CSI request field of the DCI it sends, the UE reports the first CSI report that is activated among the CSI reports associated with trigger state 1.

[0198] The terminal can configure the same trigger state for CSI reports corresponding to all possible optimal beam combinations, and then indicate the CSI report to be activated based on the inference results of the AI / ML model. This enables the network device to trigger the measurement of the optimal beam based on the inference results. The network device selects the beam for downlink transmission based on the reported CSI report, which improves the performance of AI / ML-based beam management.

[0199] It should be noted that the terminal needs to determine the content of the first CSI report based on the first information after the network device triggers the first CSI report.

[0200] Based on the above, the following details the temporal relationship between the first information and the information that triggers the first CSI report.

[0201] In one possible implementation, the first information is the information whose transmission time is closest to the transmission time of the second information, and / or the interval between the transmission time of the first information and the transmission time of the second information is less than a preset duration; wherein, the second information is the information that triggers or activates the first CSI report.

[0202] The preset duration can be configured or predefined by the network device, and this disclosure does not limit the value of the preset duration.

[0203] For example, if there are multiple first messages before the transmission time of the second message, the first message used to determine the second reference signal resources of the M groups is the message whose transmission time is closest to the second message among the multiple first messages, as shown in Figure 12. The base station transmits the first message at time n1, transmits the first message at time n2, and transmits the second message at time n3 to trigger or activate the first CSI report. Then the terminal can determine the second reference signal resources of the M groups based on the first message transmitted at time n2, measure the second reference signal resources of the M groups, generate the first CSI report and report it.

[0204] As another example, if there are multiple first messages after the transmission time of the second message, the first message used to determine the second reference signal resources of the M groups is the message whose transmission time is closest to that of the second message among the multiple first messages.

[0205] In one possible implementation, the first and second information can be combined into a single message for transmission. For example, the first information may be carried within the trigger signaling of a CSI report (e.g., DCI or MAC-CE).

[0206] For ease of understanding, the following embodiments are provided to illustrate the methods of this disclosure.

[0207] Example 1

[0208] The base station is configured with an aperiodic CSI report 1. CSI report 1 is associated with 16 first reference signal resources (RSRPs). The configuration information includes the time-domain information, frequency-domain information, and quasi-co-location information of the first reference signal resources. The content reported in CSI report 1 is Y RSRPs and their corresponding reference signal resource indices. Before triggering the aperiodic CSI report 1, the base station sends the first information shown in Figure 5, where P1 to P... 16 Used to indicate which of the 16 reference signal resources associated with CSI Report 1 are second reference signal resources, if P i =1, which means that the i-th reference signal resource among the 16 reference signal resources associated with CSI report 1 is the second reference signal resource.

[0209] When the terminal receives DCI signaling, in which the CSI request field triggers an aperiodic CSI report 1, the terminal measures the second reference signal resource indicated in the first information and reports Y RSRPs and their corresponding reference signal resource indices based on the measurement results of the second reference signal resource.

[0210] Example 2

[0211] The base station is configured with an aperiodic CSI report 1, which is associated with 16 first reference signal resources. The configuration information includes the time-domain and frequency-domain information of the first reference signal resources. The content reported by CSI report 1 is Y RSRPs and their corresponding reference signal resource indices. Before triggering the aperiodic CSI report 1, the base station sends the first information shown in Figure 13, indicating a total of S TCI states.

[0212] When the terminal receives DCI signaling, in which the CSI request field triggers aperiodic CSI report 1, the terminal reports Y RSRPs and corresponding reference signal resource indices based on the measurement results of the first S reference signal resources out of the 16 first reference signal resources associated with CSI report 1. The quasi-co-address information of these S reference signal resources is TCI state 1, TCI state 2, ..., TCI state S in the first information.

[0213] Example 3

[0214] The base station configures a semi-persistent CSI report 1, which is associated with 8 reference signal resources. The configuration information of the 8 reference signal resources includes frequency domain information and time domain information. The content reported by CSI report 1 is Y RSRPs and their corresponding reference signal resource indices. The base station activates CSI report 1 via MAC-CE signaling. The base station indicates first information, which is used to indicate the quasi-co-location information of the reference signal resources reported M times after CSI report 1 is activated, where M can be configured by the network side or indicated in the first information. The first information can be included in the signaling that activates CSI. Assuming the base station configures M=2, the first information is shown in Figure 14. Among them, X1~X3 are used to indicate the number of reference signal resources Q1 corresponding to the first report after CSI report 1 is activated, and X4~X6 are used to indicate the number of reference signal resources Q1 corresponding to the second report after CSI report 1 is activated. 2， The indicated TCI state number S = Q1 + Q2.

[0215] The terminal receives the activation signaling and first information from CSI Report 1. Based on the measurement results of the first Q1 reference signal resources out of the 8 reference signal resources associated with CSI Report 1, the terminal reports Y RSRPs and their corresponding reference signal resource indices in the first CSI report. The quasi-co-address information of these Q1 reference signal resources is TCI state 1, TCI state 2, ..., TCI state Q1 in the first information. Based on the measurement results of the first Q2 reference signal resources out of the 8 reference signal resources associated with CSI Report 1, the terminal reports Y RSRPs and their corresponding reference signal resource indices in the second CSI report. The quasi-co-address information of these Q2 reference signal resources is TCI state (Q1+1), TCI state (Q1+2), ..., TCI state S in the first information.

[0216] Example 4

[0217] The base station is configured with trigger state 1, which is associated with CSI report 1, CSI report 2, ..., CSI report 8. Each CSI report is associated with multiple reference signal resources, and the content of each CSI report is Y RSRPs and their corresponding reference signal resource indices. The base station sends the first information, as shown in Figure 11. P1 to P8 are used to indicate which of the eight CSI reports associated with trigger state 1 is the first CSI report. If P... i =1, which means that the i-th CSI report among the 8 CSI reports associated with trigger state 1 is the first CSI report.

[0218] When the terminal receives DCI signaling, in which the CSI request field triggers trigger state 1, the terminal determines the first CSI report in trigger state 1 based on the first information, and reports RSRP and the corresponding reference signal resource index based on the configuration information of these first CSI reports.
