Description

Beam processing method and device

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on November 29, 2023, with application number 202311616144.5 and application name “Beam Processing Method and Device,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a beam processing method and device. Background Art

[0003] In beam management based on artificial intelligence (AI) / machine learning (ML) model prediction, the output Top-1 / Top-K beams of the AI / ML model may be one or more beams in the predicted beam set, and the terminal has not performed actual measurement for a period of time. Because the transmission configuration indicator (TCI) indication in the related art mainly uses the measured beam to indicate the downlink signal / channel beam mode, the TCI beam indication method in the related art cannot be reused to indicate the beam output by the AI / ML model and not measured, and thus the terminal cannot accurately obtain the quasi co-location (QCL) relationship of the physical downlink shared channel (PDSCH) / physical downlink control channel (PDCCH) / channel state information reference signal (CSI Reference Signal, CSI-RS) reception.

[0108] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0112] Figure 1 shows a block diagram of a wireless communication system to which the embodiments of the present disclosure can be applied. The wireless communication system includes a terminal device 11 and a network-side device (or network device) 12. The terminal device 11 may also be referred to as a terminal or a user equipment (UE). It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present disclosure. The network-side device 12 may be a base station or a core network. It should be noted that in the embodiments of the present disclosure, only a base station in the NR system is used as an example, but the specific type of the base station is not limited.

[0113] In order to enable those skilled in the art to better understand the embodiments of the present disclosure, the following description is first given.

[0114] (1) Aperiodic CSI-RS measurement reporting;

[0115] In the NR system, CSI-RS measurement reporting includes periodic, semi-periodic, and aperiodic reporting forms. Among them, aperiodic CSI-RS measurement reporting is triggered by the CSI request field in the uplink control signaling (for example, DCI format 0_1 / _2), and each CSI request codepoint corresponds to a trigger state. Each trigger state is associated with one or more reporting configurations, and the reporting configuration includes information such as CSI-RS configuration and reporting resources. The terminal obtains the specific method of CSI-RS measurement and CSI-RS measurement result reporting based on the CSI-RS measurement reporting configuration and the instruction of the uplink control signaling.

[0116] The CSI request field size in uplink control signaling is configured via the higher-layer parameter reportTriggerSize, with a maximum bit size of 6 bits. This means that the base station can dynamically indicate the trigger state in up to 64 trigger states through the CSI request field in uplink control signaling. The association between each trigger state and the CSI-RS identification (ID) is configured by higher-layer parameters.

[0117] (2)TCI indication;

[0118] In the NR system, the terminal can configure up to 128 TCI state configurations to provide the dedicated demodulation reference signals (DM-RS) or QCL RS of CSI-RS for PDSCH / PDCCH, or QCL RS for the uplink spatial relationship (UL TX spatial filter) of PUSCH / PUCCH. For the QCL indication of the DM-RS of PDSCH, the terminal obtains the activated active TCI state list through MAC CE, and then obtains the TCI state id through the codepoint in the TCI state field in the downlink control signaling (e.g., DCI format 1_1 / 1_2), and obtains its associated CSI-RS resource id according to the high-level configuration.

[0119] (3) AI / ML beam management;

[0120] AI / ML model beam management refers to the method of inferring the optimal beam through the AI / ML model. In traditional beam management, the terminal needs to perform measurements on all beams and then report the measurement results to the base station. The base station then finds the optimal downlink beam direction based on the terminal's measurement results. In AI / ML beam management, the terminal only needs to perform measurements on some beams and report the results to the base station. The AI / ML model (a trained model) then uses the measurement results of some beams to infer the optimal beam among all beams. In this way, the network can reduce the transmission of RS signals, and the terminal can reduce the measurement of RS signals.

[0121] The input beam set of the AI / ML model is defined as set B, and the output of the AI / ML model is the predicted top-1 or top-K optimal beam in set A. One of the relationships between set A and set B is that set B is a subset of the beams in set A. For the model output, the top-1 / top-K beams may belong to set A but not set B, and these beams may not have been actually measured for a long time. To enable the terminal to accurately obtain the QCL relationship for PDSCH / PDCCH / CSI-RS reception, the network can trigger an aperiodic CSI-RS measurement report before using the top-1 / top-K beams so that the terminal can find the optimal receiving beam. However, the AI / ML inference result is not known in advance and may be any beam in set A. However, the measurement triggered by the CSI-RS request in the related art is pre-configured through RRC parameters, which makes it difficult to trigger the measurement of any beam in set A using the CSI-RS request in the related art.

[0122] For example, if an AI / ML model is deployed on the base station side, assume that set A contains 256 beams corresponding to CSI-RS IDs 0 to 255. The base station uses the AI / ML model to infer the top-K (for example, K = 1, 2, 3, etc.) optimal beams in set A, and these top-K beams have never been measured by the terminal. Because the base station does not know the CSI-RS IDs corresponding to the top-K beams before model inference, to ensure that DCI 0_1 / 0_2 can trigger aperiodic measurement / reporting of any beam in set A, the base station needs to associate a trigger state with each beam in set A.

[0123] The configuration described above has the following three problems:

[0124] (1) The number of trigger states is insufficient. In the relevant protocol, a maximum of 128 trigger states can be configured based on RRC for channel measurement and channel interference. However, the candidate number of beams in set A includes 64, 128, or 256 beams. If there are 256 beams in set A, even if all trigger states are used for channel measurement of AI / ML models, it is difficult to assign a unique trigger state to each beam. If there are 128 beams in set A, each beam corresponds to a unique trigger state, but this means that the trigger state originally used for the channel interference reference signal is occupied.

[0125] (2) The CSI-RS request field size is not large enough. The CSI-RS request field in DCI 0_1 / 0_2 in the relevant protocols is 0 to 6 bits, as configured by higher layers. This corresponds to a maximum of 64 trigger states activated by the MAC CE. If the number of beams in set A exceeds 64, for example, 128 or 256, it may not be possible to directly trigger measurement of any beam in set A using DCI 0_1 / 0_2.

[0126] (3) When K in Top-K is greater than 1, the base station needs to send multiple aperiodic CSI-RS trigger signals. For example, when K = 3, the base station needs to send at most three aperiodic CSI-RS trigger signals. Because the network cannot predict which beams make up the Top-K beam, it is also impossible to configure the association between the trigger state and the Top-K beam in advance.

[0127] The beam processing method provided by the embodiments of the present disclosure is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0128] As shown in FIG2 , an embodiment of the present disclosure provides a beam processing method, which is performed by a terminal. The method includes:

[0129] Step 201: Obtain a first trigger signaling, where the first trigger signaling is used to trigger the terminal to measure K beams output by a first AI / ML model on a first measurement resource set, where the first measurement resource set includes resources for measuring the K beams output by the first AI / ML model, where K is a positive integer.

[0130] Optionally, the first trigger signaling carries a first trigger state, and the first trigger state is associated with the first measurement resource set.

[0131] The first measurement resource set includes at least one resource subset, each resource subset includes at least one measurement resource, and each resource subset corresponds to a beam output by the first AI / ML model;

[0132] The measurement resources in each resource subset use the same downlink spatial filter, and the measurement resources in different resource subsets use different downlink spatial filters, and the measurement resources in each resource subset are used for receive beam scanning.

[0133] The above-mentioned resource subset can correspond to any beam output by the first AI / ML model (or the reference signal corresponding to the beam, such as CSI-RS), and the correspondence (or association) between the above-mentioned resource subset and the beam output by the first AI / ML model is dynamically changeable.

[0134] For example, the first measurement resource first corresponds to beam one, that is, the reference signal carried on this measurement resource adopts the same downlink spatial filter as the direction of beam one. When the next beam measurement is triggered, the association between the first measurement resource and the beam direction is updated to the reference signal carried on the first measurement resource adopts the same downlink spatial filter as the direction of beam two.

[0135] Optionally, the correspondence between the above-mentioned AI / ML model output beam or the first measurement resource set or the first trigger signaling and the beam information can be indicated through high-layer signaling or physical layer signaling. The high-layer signaling includes MAC CE signaling, which can be carried by PDSCH, and the physical layer signaling includes downlink control signaling.

[0136] Step 202: Measure the reference signal on the first measurement resource set to obtain an optimal receiving beam corresponding to the downlink transmission beam of the reference signal, wherein the downlink transmission beam includes at least one beam among the K beams.

[0137] Optionally, the above-mentioned reference signal includes a CSI-RS, and the measurement in the embodiment of the present disclosure refers to performing aperiodic CSI-RS measurement on the first measurement resource set.

[0138] For example, the optimal receiving beam is the receiving beam with the highest RSRP.

[0139] In an embodiment of the present disclosure, multiple AL / ML models may be deployed on the base station or terminal side, each AL / ML model has a corresponding AI / ML model output result (output beam), each AL / ML model is associated with a trigger state, and each trigger state is associated with a measurement resource set. For example, AI / ML model 1 is associated with trigger state 1, and trigger state 1 is associated with measurement resource set 1; AI / ML model 2 is associated with trigger state 2, and trigger state 2 is associated with measurement resource set 2.

[0140] If the base station triggers the measurement of the aperiodic CSI-RS in trigger state 1 through DCI, the terminal performs the aperiodic CSI-RS measurement on the measurement resource set 1 associated with trigger state 1, that is, performs the measurement on the output beam of AI / ML model 1. If the base station triggers the measurement of the aperiodic CSI-RS in trigger state 2 through DCI, the terminal performs the aperiodic CSI-RS measurement on the measurement resource set 2 associated with trigger state 2, that is, performs the measurement on the output beam of AI / ML mode 2.

[0163] In this implementation, the association between the MAC CE or DCI and the measurement resource set or trigger signaling is indicated in an implicit manner.

[0164] Optionally, the method of the embodiment of the present disclosure further includes:

[0165] Determine that the beam corresponding to the identification information indicated by the first MAC CE or the first DCI is in an activated state.

[0166] In the disclosed embodiment, the beam corresponding to the identification information indicated by the first MAC CE or the first DCI is directly indicated as being in an activated state and mapped to one or more codepoints. The mapping relationship includes direct mapping to a default codepoint, for example, K beam direction IDs / CSI-RS IDs corresponding to the first / last K codepoints, and the original activated codepoints are updated based on the removal of K codepoints; or the codepoints are directly updated in order based on the original activation state.

[0167] Optionally, the first DCI satisfies at least one of the following:

[0171] The second target domain is reused to indicate the association relationship between the DCI and the measurement resource set or trigger signaling, and the second target domain includes at least one of the transmission configuration indication TCI indication domain, the MCS indication domain, the antenna port (Antenna port) indication domain and the demodulation reference signal DMRS domain.

[0172] In the embodiment of the present disclosure, the association relationship between the DCI and the first measurement resource set or the first trigger signaling may be implicitly indicated by the above-mentioned specific DCI format (default DCI format).

[0173] In an embodiment of the present disclosure, a first trigger signaling is obtained, and the first trigger signaling is used to trigger the terminal to measure the K beams output by the first AI / ML model on a first measurement resource set, and the first measurement resource set includes resources for measuring the K beams output by the first AI / ML model; a reference signal is measured on the first measurement resource set to obtain an optimal receiving beam corresponding to the downlink transmit beam of the reference signal, wherein the downlink transmit beam includes at least one of the K beams. Through the above scheme, the terminal can measure any beam output by the AI / ML model, so that the network can reuse the TCI beam indication method in the related technology to indicate the downlink signal / channel beam method of the beam output by the AI / ML model and measured, thereby enabling the terminal to accurately obtain the QCL relationship of PDSCH / PDCCH / CSI-RS reception based on the beam output by the AI / ML model.

[0174] As shown in FIG3 , an embodiment of the present disclosure further provides a beam processing method, which is performed by a network-side device. The method includes:

[0175] Step 301: Send a first trigger signaling, where the first trigger signaling is used to trigger the terminal to measure K beams output by a first AI / ML model on a first measurement resource set, where the first measurement resource set includes resources for measuring the K beams output by the first AI / ML model, where K is a positive integer.

[0176] Optionally, the first trigger signaling carries a first trigger state, and the first trigger state is associated with the first measurement resource set.

[0177] The first measurement resource set includes at least one resource subset, each resource subset includes at least one measurement resource, and each resource subset corresponds to a beam output by the first AI / ML model;

[0178] The measurement resources in each resource subset use the same downlink spatial filter, and the measurement resources in different resource subsets use different downlink spatial filters, and the measurement resources in each resource subset are used for receive beam scanning.

[0179] The above-mentioned resource subset can correspond to any beam output by the first AI / ML model (or the reference signal corresponding to the beam, such as CSI-RS), and the correspondence (or association) between the above-mentioned resource subset and the beam output by the first AI / ML model is dynamically changeable.

[0180] For example, the first measurement resource first corresponds to beam one, that is, the reference signal carried on this measurement resource adopts the same downlink spatial filter as the direction of beam one. When the next beam measurement is triggered, the association between the first measurement resource and the beam direction is updated to the reference signal carried on the first measurement resource adopts the same downlink spatial filter as the direction of beam two.

[0181] Optionally, the correspondence between the above-mentioned resource subset and the beam output by the first AI / ML model (or the reference signal corresponding to the beam) can be indicated through high-layer signaling or physical layer signaling. The high-layer signaling includes MAC CE signaling, which can be carried by PDSCH. The physical layer signaling includes downlink control signaling.

[0182] In an embodiment of the present disclosure, a first trigger signaling is sent, and the first trigger signaling is used to trigger the terminal to measure the K beams output by the first AI / ML model on a first measurement resource set. The first measurement resource set includes resources for measuring the K beams output by the first AI / ML model, so that the terminal can measure any beam output by the AI / ML model, so that the network can reuse the TCI beam indication method in the related technology to indicate the downlink signal / channel beam method of the beam output by the AI / ML model and measured, thereby enabling the terminal to accurately obtain the QCL relationship of PDSCH / PDCCH / CSI-RS reception based on the beam output by the AI / ML model.

[0185] Exemplarily, the identification information indicated by the first beam indication information is the beam direction ID or CSI-RS ID corresponding to the highest layer 1 reference signal received power (Layer 1 reference signal received power, L1-RSRP).

[0186] As an implementation manner, sending the first beam indication information includes:

[0187] The first beam indication information is sent through a first media access control element MAC CE or first downlink control information DCI.

[0188] As an implementation manner, the first MAC CE or the first DCI includes first indication information, and the first indication information is used to indicate that the first MAC CE or the first DCI is a MAC CE or DCI associated with the first measurement resource set or the first trigger signaling.

[0189] Optionally, the first indication information is used to indicate that a time slot in which the first MAC CE or the first DCI is located is associated with a time slot in which the first measurement resource set or the first trigger signaling is located;

[0190] Alternatively, the first indication information is used to indicate that the first MAC CE or the first DCI is associated with an identifier of a measurement resource set or an identifier of a triggering signaling.

[0191] In an embodiment of the present disclosure, the identifier of the measurement resource set associated with the MAC CE or DCI or the identifier of the trigger signaling can be directly indicated by the above-mentioned first indication information, or the measurement resource set or trigger signaling associated with the MAC CE or DCI can be indicated by indicating the time slot relationship (such as indicating the time slot offset between the two).

[0192] Optionally, the first MAC CE or the first DCI satisfies at least one of the following:

[0193] Sending in a first time window, where the first time window is a time window of a preset length after the time domain position corresponding to the first trigger signaling;

[0194] It is sent in the first time slot, where the first time slot includes M time slots after the time slot where the first trigger signaling is located, where M is a positive integer.

[0195] In this implementation, the association between the MAC CE or DCI and the measurement resource set or trigger signaling is indicated in an implicit manner.

[0196] Optionally, the first DCI satisfies at least one of the following:

[0197] Scrambled by the configured scheduling radio network temporary identifier CS-RNTI;

[0198] The frequency domain resource allocation field FDRA field is all 0 or all 1;

[0199] The first target field is set to a default value, wherein the first target field includes at least one of a redundancy version RV field, a modulation and coding scheme MCS indication field, and a new data identifier NDI indication field;

[0200] The second target domain is reused to indicate the association relationship between the DCI and the measurement resource set or trigger signaling, and the second target domain includes at least one of the transmission configuration indication TCI indication domain, the MCS indication domain, the antenna port indication domain and the demodulation reference signal DMRS domain.

[0201] In the embodiment of the present disclosure, the association relationship between the DCI and the first measurement resource set or the first trigger signaling may be implicitly indicated by the above-mentioned specific DCI format (default DCI format).

[0202] Optionally, the method of the embodiment of the present disclosure further includes:

[0203] Configure the first measurement resource set associated with the first trigger signaling.

[0204] The beam processing method disclosed herein is described below with reference to embodiments.

[0205] Example 1:

[0206] In this embodiment, the AI / ML model deployed on the base station, terminal, or server predicts the optimal beam Top-K beams (K≥1) in set A based on the measurement of the beams in set B.

[0207] The base station configures a resource set in the CSI aperiodic trigger list (CSI-AperiodicTriggerStateList). This resource set is associated with the output beam of the AI / ML model and is used to configure aperiodic measurements of the AI / ML output beam. A new AI / ML model output beam measurement resource set is added to the CSI aperiodic trigger list. One implementation of the CSI aperiodic trigger list IE is as follows:

[0208] One or more sub-resource sets are configured in the measurement resource set. Each resource subset corresponds to one of the beams output by the AI / ML model / function, and the resources within each resource subset use the same downlink spatial filter. In other words, the AI / ML model output beam measurement resource set is a three-layer configuration. The first layer is to configure the resource set for output beam measurement based on the AI / ML model. The second layer is to configure different resource subsets in the resource set for carrying different output beams. The third layer is to configure different resources within the resource subset for receiving beam scanning. The configuration method of the resource set for AI / ML model output beam measurement is as follows:

[0209] After the base station triggers measurement of the measurement resources of the AI / ML model output beam, the base station will send a reference signal on each sub-resource set using one of the beams output by the AI / ML model / function. The terminal will measure the reference signal received power (RSRP) on the resources within each sub-resource set in the form of receive beam scanning and store the receive beam with the highest RSRP corresponding to each resource subset, or store the receive beam with the highest RSRP in the resource set.

[0210] Optionally, whether the beams in each subset use the same downlink filter can be configured based on a 1-bit switch. For example, one state indicates that the beams in the subset use the same downlink filter, while the other state indicates that the beams in the subset do not need to use the same downlink filter. In other words, whether the beams in each subset use the same downlink filter can be configured at the subset level. An optional configuration method is as follows:

[0211] Optionally, the number of resource subcollections in a resource collection can be configured as follows:

[0212] 1) If a measurement resource set is associated one-to-one with an AI / ML model or AI / ML function, the number of sub-resource sets is the same as the number of output beams of the AI / ML model / function.

[0213] 2) If a resource collection has a one-to-many relationship with an AI / ML model / function, the number of sub-resource collections is equal to the maximum number of output beams of the AI / ML model / function.

[0214] Optionally, the number of resources in a resource subset is the same as the number of receiving beams of the terminal.

[0215] Example 2:

[0216] In this embodiment, when the base station triggers the non-periodic measurement reporting of the measurement resource set corresponding to the AI / ML model / function, the base station will use the latest AI / ML model / function inferred beam to send the reference signal on the measurement resource, and the terminal will perform L1-RSRP measurement on each measurement resource, that is, perform measurement on the beam inferred by the AI / ML model / function, and cache the optimal receiving beam corresponding to each resource subset in the resource set. The base station will subsequently notify the terminal of the triggered / measured beam number. After this, the base station can instruct the terminal to use the beam inferred by AI / ML to send the downlink signal / channel through TCI / QCL indication. Since the terminal has cached the optimal receiving beam corresponding to the beam inferred by AI / ML, the optimal receiving beam can be used to receive the downlink signal / channel based on the implementation.

[0217] For example, a base station triggers aperiodic measurements of the resource set with ID = 1 corresponding to the AI / ML model / function at both times T1 and T2. T1 is the earlier time, and T2 is the later time. Furthermore, the most recent optimal beam based on AI / ML model reasoning before T1 is beam ID = 16, and the most recent optimal beam based on AI / ML model reasoning before T2 is beam ID = 64.

[0218] T1 moment:

[0219] Base station side

[0220] Step 1: The base station sends an aperiodic measurement trigger signaling (i.e., the first trigger signaling) at time T1. This signaling is used to trigger aperiodic measurement of the resource set with ID=1 corresponding to the AI / ML model / function (i.e., the first measurement resource set).

[0221] Step 2: Because the most recent optimal beam inference based on the AI / ML model / function before time T1 is beam ID = 16, the base station transmits a reference signal in the direction of beam ID = 16 on the triggered resource set. This reference signal may be a CSI-RS signal.

[0222] Step 3: The base station subsequently indicates the ID=16 or CSI-RS ID corresponding to the beam direction, that is, sends the identifier corresponding to the triggered beam.

[0223] Terminal side

[0224] Step 1: The terminal receives a non-periodic measurement trigger signaling at time T1.

[0225] Step 2: The terminal measures the reference signal on the triggered resource set based on the configuration by scanning the receive beam. The terminal caches the receive beam corresponding to the highest L1-RSRP as the optimal receive beam for measurement, such as RX1.

[0226] Step 3: The terminal subsequently receives an identifier corresponding to the measured beam mode, such as beam ID=16, or CSI-RS ID.

[0227] After that, the base station can instruct the terminal to use beam / CSI-RS ID=16 to send downlink signals / channels through TCI / QCL indication, and the terminal can use the optimal receiving beam RX1 for reception.

[0228] T2 moment:

[0229] Base station side

[0230] Step 1: The base station sends an aperiodic measurement trigger signaling (i.e., the first trigger signaling mentioned above) at time T2. This signaling is used to trigger the aperiodic measurement of the resource set with ID=1 corresponding to the AI / ML model / function.

[0231] Step 2: Because the most recent optimal beam inference based on the AI / ML model / function before time T2 is beam ID = 64, the base station transmits a reference signal in the direction of beam ID = 64 on the triggered resource set. This reference signal may be a CSI-RS signal.

[0232] Step 3: The base station subsequently indicates the ID=64 or CSI-RS ID corresponding to the beam direction, that is, sends the identification number corresponding to the triggered beam.

[0233] Terminal side

[0234] Step 1: The terminal receives a non-periodic measurement trigger signaling at time T2.

[0235] Step 2: The terminal measures the reference signal on the triggered resource set based on the configuration by scanning the receive beam. The terminal caches the receive beam corresponding to the highest L1-RSRP as the optimal receive beam for measurement, such as RX2.

[0236] Step 3: The terminal subsequently receives an identification number corresponding to the measured beam mode, such as beam ID=64, or CSI-RS ID.

[0237] After that, the base station can instruct the terminal to use beam / CSI-RS ID=64 to send downlink signals / channels through TCI / QCL indication, and the terminal can use the optimal receiving beam RX2 for reception.

[0238] Example 3:

[0239] In this embodiment, after the base station uses the beam inferred by the latest AI / ML model / function to send a reference signal, the base station indicates the beam identification number or CSI-RS ID through MAC CE signaling. The terminal obtains the optimal receiving beam corresponding to the downlink transmit beam based on the measurement of the reference signal, and then obtains the identification number or CSI-RS ID of each downlink transmit beam through MAC CE. Each transmit beam identification number or CSI-RS ID corresponds to a TCI codepoint, and the base station can use the TCI field to indicate the use of the beam inferred by the AI / ML model / function for downlink signal / channel transmission.

[0240] The design methods for MAC CE include the following:

[0241] Solution 1: The MAC CE includes a serving cell ID, a bandwidth part ID (BWP ID), and one or more beam numbers or CSI-RS IDs. Each beam number or CSI-RS ID corresponds one-to-one to each sub-resource set in Example 1, and the correspondence is performed in ascending / descending order of the sub-resource set IDs. For example, the first beam / CSI-RS ID corresponds to the first sub-resource set, the second beam / CSI-RS ID corresponds to the second sub-resource set, and so on. This is shown in Figure 4.

[0242] The association relationship between the information carried by the MAC CE and the first measurement resource set:

[0243] Solution 1-1: The information carried by the MAC CE is associated with the measurement resources in the first measurement resource set that is closest in the time domain before receiving the MAC CE or the trigger signaling that is closest in the time domain.

[0244] Solution 1-2: There is a time window T after the aperiodic measurement trigger signaling, and the MAC CE received within the time window T is associated with the aperiodic measurement trigger signaling.

[0245] Solution 1-3: By default, this MAC CE is sent within M downlink time slots after the non-periodic measurement trigger signaling. The value of M can be a default value / dynamic indication / high-layer configuration.

[0246] Solution 2: The MAC CE includes the serving cell ID, BWP ID, one or more beam numbers or CSI-RS IDs, and the time slot relationship with the aperiodic measurement trigger signaling, as shown in Figure 5. Compared to Solution 1, the "time slot relationship K between the aperiodic measurement trigger signaling" is added to explicitly indicate the time slot interval between this MAC CE and the aperiodic measurement trigger signaling. For example, when K = 16 in the MAC CE, assuming the MAC CE is time slot n, the aperiodic measurement trigger signaling associated with the MAC CE is in time slot nK.

[0247] Solution 2-1: The MAC CE / DCI includes a measurement resource set identifier or a trigger signaling identifier or an AI / ML model ID, which explicitly indicates the association between the MAC CE / DCI and the measurement resource set or trigger signaling or AI / ML model.

[0248] Solution 3: In addition to Solution 1 and Solution 2, the MAC CE also carries the TCI codepoint corresponding to each beam number / CSI-RS ID, as shown in Figure 6. When the base station sends a MAC CE carrying one or more beam numbers / CSI-RS IDs and the corresponding TCI codepoint, the beam number / CSI-RS ID indicated by the TCI codepoint is considered to be active. The base station can use this TCI codepoint to indicate the downlink signal or channel.

[0249] Example 4:

[0250] In this embodiment, the base station indicates the beam number / CSI-RS ID in the first measurement resource set through DCI, and the DCI is designed as follows:

[0251] Solution 1: This DCI format 1_1 / 1_2 is scrambled by the CS-RNTI. The FDRA field is set to all '0's or all '1's. The MCS cannot be set to all 1s. RV = 1, and NDI = 1. Multiple fields in the DCI, including the TCI indicator field, MCS indicator field, antenna port indicator field, DMRS field, or other fields, form a bitmap that indicates one or more beam numbers or CSI-RS IDs. The bit length and position of each beam number or CSI-RS in the bitmap are configured by higher layers.

[0252] Solution 2: This DCI format 1_1 / 1_2 is scrambled by the CS-RNTI, the FDRA field is set to all '0' or all '1', the MCS cannot be set to all 1, RV = 0, NDI = 1. The method for indicating the beam number or CSI-RS ID is the same as that in Solution 1.

[0253] Solution 3: This DCI format 1_1 / 1_2 is scrambled by the CS-RNTI, the FDRA field is set to all '0' or all '1', the MCS cannot be set to all 1, RV = 0, NDI = 0. The method for indicating the beam number or CSI-RS ID is the same as that in Solution 1.

[0254] Solution 4: This DCI format 1_1 / 1_2 is scrambled by the CS-RNTI, the FDRA field is set to all '0' or all '1', the MCS is set to all 0, and RV = 0. The NDI field is added to the available bit field. Other methods for indicating the beam number or CSI-RS ID are the same as in Solution 1.

[0255] As an optional solution, a bitemap can be used to explicitly indicate the associated first resource ID or the time slot relationship with the aperiodic measurement trigger signaling. Alternatively, the relationship between the DCI and the first resource set to be measured can be determined by referring to the fixed time window, after M slots, or the most recent aperiodic measurement trigger signaling.

[0256] The solution of the embodiment of the present disclosure enables the network to instruct the terminal to perform measurements on any reference signal through a limited trigger state to obtain the optimal receiving beam, and further indicates to the terminal its corresponding reference signal identifier for QCL / TCI status indication during transmission.
