Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a beam processing method and apparatus. Background Art

[0002] In beam management based on predictions of an Artificial Intelligence (AI) / Machine Learning (ML) model, 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 does not perform actual measurements for a period of time. Since the existing Transmission Configuration Indicator (TCI) indication mainly uses the measured beams to indicate the downlink signal / channel beam mode, it is not possible to reuse the existing TCI beam indication method to indicate the beams output by the AI / ML model that have not been measured. As a result, the terminal cannot accurately obtain the Quasi Co-Location (QCL) relationship for receiving the Physical Downlink Shared Channel (PDSCH) / Physical Downlink Control Channel (PDCCH) / CSI Reference Signal (CSI-RS).

[0110] Figure 1The block diagram of a wireless communication system to which the embodiments of the present application can be applied is shown. The wireless communication system includes a terminal device 11 and a network-side device (or network device) 12. Among them, the terminal device 11 can also be referred to as a terminal or a user terminal (User Equipment, UE). It should be noted that in the embodiments of the present application, the specific type of the terminal 11 is not limited. The network-side device 12 can be a base station or a core network. It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0111] To enable those skilled in the art to better understand the embodiments of the present application, the following explanations are made first.

[0112] (1) Aperiodic CSI-RS measurement reporting;

[0113] 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). 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 manner of CSI-RS measurement and CSI-RS measurement result reporting according to the configuration of CSI-RS measurement reporting and the indication of the uplink control signaling.

[0114] In the uplink control signaling, the size of the CSI request field is configured by the high-layer parameter reportTriggerSize, and the maximum bit size is 6 bits. This means that the base station can dynamically indicate the trigger state among up to 64 trigger states through the CSI request field of the uplink control signaling, and the association relationship between each trigger state and the CSI-RS ID is configured by the high-layer parameter.

[0115] (2) TCI indication;

[0116] In the NR system, the terminal can configure up to 128 TCI states, which are used to provide the dedicated demodulation reference signals (DM-RS) of PDSCH / PDCCH or the QCL RS of CSI-RS, or provide the QCL RS of 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 list of active TCI states (active TCI state list) through the 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 the associated CSI-RS resource id according to the high-layer configuration.

[0117] (3) AI / ML beam management;

[0118] The beam management of the AI / ML model 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 measurement results of the terminal. In AI / ML beam management, the terminal only needs to perform measurements on some beams, report the results to the base station, and the AI / ML model (the trained model) then infers the optimal beam among all beams using the measurement results of some beams. In this way, the network can reduce the transmission of RS signals, and the terminal can reduce the measurement of RS signals.

[0119] The input beam set of the AI / ML model is defined as set B, and the output of the AI / ML model is the Top-1 or Top-K optimal beams in the predicted set A beam set. Among them, 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 output of the model, there may be cases where the Top-1 / Top-K beams belong to set A but not to set B, and these beams may not have been actually measured for a long time. In order for the terminal to accurately obtain the QCL relationship for PDSCH / PDCCH / CSI-RS reception, before using the Top-1 / Top-K beams, the network can trigger an aperiodic CSI-RS measurement report so that the terminal can find the optimal receiving beam. However, the inference result of AI / ML is not known in advance and may be any beam in set A, but in the prior art, the measurement triggered by the CSI-RS request is pre-configured through RRC parameters, which makes it difficult to trigger the measurement of any beam in set A using the existing CSI-RS request.

[0120] Taking the case where the AI / ML model is deployed on the base station side as an example, assume that there are 256 beams in set A corresponding to CSI-RS ID = 0 to 255 respectively. The base station infers the Top-K (for example, K = 1, 2, 3..) optimal beams in set A through the AI / ML model and these Top-K beams have never been measured by the terminal. Since the base station does not know the CSI-RS ID corresponding to the Top-K beams before model inference, in order to ensure that the aperiodic measurement / report of any beam in set A can be triggered by DCI 0_1 / 0_2, the base station needs to associate a trigger status with each beam in set A.

[0121] Configuring in the above manner has the following three problems:

[0122] (1) The number of trigger status settings is insufficient. In the existing protocol, based on RRC, at most 128 trigger statuses can be configured for channel measurement and channel interference. However, the number of candidate beams in set A includes options of 64, 128, or 256 beams. If there are 256 beams in set A, even if all trigger statuses are used for channel measurement of the AI / ML model, it is difficult to assign a unique trigger status to each beam. If there are 128 beams in set A, each beam corresponds to a unique trigger status, but this also means that the trigger status originally used for the channel interference reference signal is occupied.

[0123] (2) The CSI-RS request field size is not large enough. In the existing protocol, the CSI-RS request field in DCI 0_1 / 0_2 is configured as 0 to 6 bits according to the high-layer configuration, corresponding to a maximum of 64 trigger states activated by the MAC CE. If the number of beams in set A is more than 64, such as 128 or 256, it may not be possible to directly trigger the measurement of any beam in set A through DCI 0_1 / 0_2.

[0124] (3) When K > 1 in Top-K, the base station needs to send multiple non-periodic CSI-RS trigger signaling. For example, when K = 3, the base station needs to send at most three non-periodic CSI-RS trigger signaling. Since the network cannot predict in advance which beams the Top K beams consist of, it is impossible to pre-configure the association relationship between the trigger state and the Top-K beams.

[0125] The beam processing method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0126] As Figure 2 shown, the embodiments of the present application provide a beam processing method, which is executed by a terminal. The method includes:

[0127] Step 201: Obtain a first trigger signaling, where the first trigger signaling is used to trigger the terminal to measure K beams output by the first AI / ML model on a first measurement resource set. The first measurement resource set includes resources for measuring K beams output by the first AI / ML model, and K is a positive integer.

[0128] Optionally, the first trigger signaling carries a first trigger state, and the first trigger state is associated with the first measurement resource set.

[0129] 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 one beam output by the first AI / ML model;

[0130] Among them, the measurement resources within each resource subset use the same downlink spatial filter, and the measurement resources within different resource subsets use different downlink spatial filters, and the measurement resources within each resource subset are used for receiving beam scanning.

[0131] The above resource subset can correspond to any one beam (or the reference signal corresponding to the beam, such as CSI-RS) output by the first AI / ML model, and the corresponding relationship (or association relationship) between the resource subset and the beam output by the first AI / ML model is dynamically variable.

[0132] For example, the first measurement resource first has a corresponding relationship with beam one, that is, the reference signal carried on this measurement resource uses the same downlink spatial filter as the direction of beam one. When triggering the next beam measurement, the association relationship between the first measurement resource and the beam direction is updated so that the reference signal carried on the first measurement resource uses the same downlink spatial filter as the direction of beam two.

[0133] Optionally, the correspondence between the beam or the first measurement resource set or the first trigger signaling and the beam information output by the above AI / ML model can be indicated by high-layer signaling or physical-layer signaling. The high-layer signaling includes MAC CE signaling, and the MAC CE signaling can be carried by PDSCH. The physical-layer signaling includes downlink control signaling.

[0134] 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, where the downlink transmission beam includes at least one beam among the K beams.

[0135] Optionally, the above reference signal includes CSI-RS, and the measurement in the embodiments of this application refers to performing an aperiodic CSI-RS measurement on the first measurement resource set.

[0136] For example, the above optimal receiving beam is the receiving beam with the highest RSRP.

[0137] In the embodiments of this application, multiple AL / ML models can be deployed on the base station or the 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.

[0138] If the base station triggers an aperiodic CSI-RS measurement for trigger state 1 through DCI, the terminal performs an aperiodic CSI-RS measurement on the measurement resource set 1 associated with trigger state 1, that is, measures the output beam of AI / ML model 1. If the base station triggers an aperiodic CSI-RS measurement for trigger state 2 through DCI, the terminal performs an aperiodic CSI-RS measurement on the measurement resource set 2 associated with trigger state 2, that is, measures the output beam of AI / ML model 2.

[0139] In an embodiment of the present application, a first trigger signaling is obtained. The first trigger signaling is used to trigger a 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; a reference signal is measured on the first measurement resource set to obtain an optimal receiving beam corresponding to the downlink transmission beam of the reference signal, where the downlink transmission beam includes at least one beam among the K beams. Through the above solution, the terminal can measure any beam output by the AI / ML model, so that the network can reuse the existing TCI beam indication method to indicate the downlink signal / channel beam mode for the beams output by the AI / ML model and that have been measured, and further enable the terminal to accurately obtain the QCL relationship of PDSCH / PDCCH / CSI-RS reception based on the beams output by the AI / ML model.

[0148] In the embodiments of the present application, the identification information of the above-mentioned downlink transmission beam or the identification information of the reference signal corresponding to the downlink transmission beam can be indicated by MAC CE or DCI, so that the base station can subsequently indicate, in the manner of TCI / QCL indication, that the terminal will use the beam inferred by AI / ML to transmit downlink signals / channels. In the embodiments of the present application, the MAC CE or DCI for indicating the identification information of the above-mentioned downlink transmission beam or the identification information of the reference signal corresponding to the downlink transmission beam is the MAC CE or DCI carrying specific information, that is, the identification information of the above-mentioned downlink transmission beam or the identification information of the reference signal corresponding to the downlink transmission beam is indicated by the MAC CE or DCI in a specific format.

[0149] As an optional implementation manner, determining the first MAC CE or the first DCI includes:

[0150] Obtain the first indication information in the MAC CE or DCI, where the first indication information is used to indicate the association relationship between the MAC CE or DCI and the measurement resource set or the trigger signaling;

[0151] When the first indication information indicates that the MAC CE or DCI is the MAC CE or DCI associated with the first measurement resource set or the first trigger signaling, determine that the MAC CE or DCI is the first MAC CE or the first DCI.

[0152] The above-mentioned measurement resource set is the resource for measuring the K beams output by the AI / ML model, and the above-mentioned trigger signaling is the signaling for triggering the terminal to perform aperiodic measurement of the K beams output by the associated AI / ML model on the measurement resource set.

[0153] This implementation manner explicitly indicates the association relationship between the MAC CE or DCI and the measurement resource set or the trigger signaling through the first indication information.

[0154] Optionally, the first indication information is used to indicate the association relationship between the time slot where the MAC CE or DCI is located and the time slot where the measurement resource set or the trigger signaling is located;

[0155] Alternatively, the first indication information is used to indicate the association relationship between the MAC CE or DCI and the identification of the measurement resource set or the identification of the trigger signaling or the AI / ML model identification.

[0156] In the embodiments of the present application, the identity of the measurement resource set associated with the MAC CE or DCI, or the identity of the triggering signaling, or the AI / ML model identity can be directly indicated by the above first indication information, or the measurement resource set or triggering 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).

[0160] The above M time slots include uplink time slots and downlink time slots, or include downlink time slots. These M time slots can be continuous or discontinuous. For example, the above M time slots are M consecutive downlink time slots.

[0161] In this implementation, the association relationship between the MAC CE or DCI and the measurement resource set or the triggering signaling is indicated in an implicit manner.

[0162] Optionally, the method of the embodiments of the present application further includes:

[0163] Determining that the beam corresponding to the identity information indicated by the first MAC CE or the first DCI is in an active state.

[0164] In the embodiments of the present application, the beam corresponding to the identity information indicated by the first MAC CE or the first DCI is directly indicated as being in an active state and is mapped to one or more codepoints. The mapping relationship includes directly mapping to a default codepoint. For example, K beam direction IDs / CSI-RS IDs correspond to the first / last K codepoints, and the codepoints in the original active state are updated after removing the K codepoints; or directly updating the codepoints in sequence based on the original active state.

[0165] Optionally, the first DCI satisfies at least one of the following:

[0166] Scrambled by the configured scheduling radio network temporary identity CS-RNTI;

[0167] The Frequency Domain Resource Assignment (FDRA) field is all 0s or all 1s.

[0168] The first target field is set to a default value, and the first target field includes at least one of a Redundant Version (RV) field, a Modulation and Coding Scheme (MCS) indication field, and a New Data Indicator (NDI) indication field.

[0169] Reuse the indication relationship between the second target field and the DCI and the measurement resource set or the triggering signaling. The second target field includes at least one of a Transmission Configuration Indicator (TCI) indication field, an MCS indication field, an Antenna port indication field, and a Demodulation Reference Signal (DMRS) field.

[0170] In the embodiments of the present application, the indication relationship between the DCI and the first measurement resource set or the first triggering signaling can be implicitly indicated by the above specific DCI format (default DCI format).

[0171] In the embodiments of the present application, obtain a first triggering signaling, where the first triggering signaling is used to trigger a terminal to measure K beams output by a 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; measure a reference signal on the first measurement resource set to obtain an optimal receiving beam corresponding to a downlink transmission beam of the reference signal, where the downlink transmission beam includes at least one of the K beams. Through the above solution, the terminal can measure any beam output by the AI / ML model, so that the network can reuse the existing TCI beam indication method to indicate the downlink signal / channel beam mode of the beam output by the AI / ML model and already measured, and further enable the terminal to accurately obtain the QCL relationship of PDSCH / PDCCH / CSI-RS reception based on the beam output by the AI / ML model.

[0172] As Figure 3 shown, the embodiments of the present application further provide a beam processing method, which is executed by a network-side device, and the method includes:

[0173] Step 301: Send a first triggering signaling, where the first triggering signaling is used to trigger a terminal to measure K beams output by a 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, and K is a positive integer.

[0174] Optionally, the first trigger signaling carries a first trigger state, and the first trigger state is associated with the first measurement resource set.

[0175] The above-mentioned first measurement resource set includes at least one resource subset, each resource subset includes at least one measurement resource, and each of the resource subsets corresponds to a beam output by the first AI / ML model;

[0176] Among them, the measurement resources within each resource subset use the same downlink spatial filter, and the measurement resources within different resource subsets use different downlink spatial filters, and the measurement resources within each resource subset are used for receiving beam scanning.

[0177] The above-mentioned resource subset can correspond to any beam (or the reference signal corresponding to the beam, such as CSI-RS) output by the first AI / ML model, and the corresponding relationship (or association relationship) between the resource subset and the beam output by the first AI / ML model is dynamically variable.

[0178] For example, the first measurement resource first has a corresponding relationship with beam one, that is, the reference signal carried on this measurement resource uses the same downlink spatial filter as the direction of beam one. When triggering the next beam measurement, the association relationship between the first measurement resource and the beam direction is updated to that the reference signal carried on the first measurement resource uses the same downlink spatial filter as the direction of beam two.

[0179] Optionally, the corresponding relationship between the above-mentioned resource subset and the beam (or the reference signal corresponding to the beam) output by the first AI / ML model can be indicated by high-layer signaling or physical-layer signaling. The high-layer signaling includes MAC CE signaling, and the MAC CE signaling can be carried by PDSCH. The physical-layer signaling includes downlink control signaling.

[0180] In the embodiment of the present application, a first trigger signaling is sent. The first trigger signaling is used to trigger the terminal to measure K beams output by the first AI / ML model on the first measurement resource set. The first measurement resource set includes resources for measuring the K beams output by the first AI / ML model. Thus, the terminal can measure any beam output by the AI / ML model, so that the network can reuse the existing TCI beam indication method to indicate the downlink signal / channel beam mode of the beam that has been measured and output by the AI / ML model, and further enable the terminal to accurately obtain the QCL relationship of PDSCH / PDCCH / CSI-RS reception based on the beam output by the AI / ML model.

[0181] Optionally, the method of the embodiment of the present application further includes:

[0182] Send first beam indication information, where the first beam indication information is beam indication information associated with the first trigger signaling or the first measurement resource set; and the first beam indication information is used to indicate the identification information of the downlink transmission beam or the identification information of the reference signal corresponding to the downlink transmission beam.

[0183] Exemplarily, the identification information indicated by the above first beam indication information is the beam direction ID or CSI-RSID corresponding to the highest layer 1 reference signal received power (L1-RSRP).

[0184] As an implementation manner, sending the first beam indication information includes:

[0185] Send the first beam indication information through a first media access control unit MAC CE or a first downlink control information DCI.

[0186] 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.

[0187] Optionally, the first indication information is used to indicate that the time slot where the first MAC CE or the first DCI is located is associated with the time slot where the first measurement resource set or the first trigger signaling is located;

[0188] Alternatively, the first indication information is used to indicate that the first MAC CE or the first DCI is associated with the identification of the measurement resource set or the identification of the trigger signaling.

[0189] In the embodiments of the present application, the identification of the measurement resource set or the trigger signaling associated with the MAC CE or DCI can be directly indicated by the above first indication information, or the measurement resource set or the 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).

[0190] Optionally, the first MAC CE or the first DCI satisfies at least one of the following:

[0191] Send in a first time window, where the first time window is a time window located after a preset duration corresponding to the time domain position of the first trigger signaling;

[0192] Send in a first time slot, where the first time slot includes M time slots after the time slot where the first trigger signaling is located, and M is a positive integer.

[0193] 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.

[0194] Optionally, the first DCI satisfies at least one of the following:

[0195] Scrambled by the configuration scheduling radio network temporary identifier CS-RNTI;

[0196] The frequency domain resource allocation field FDRA field is all 0 or all 1;

[0197] 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;

[0198] The reused second target domain indicates 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.

[0199] In an embodiment of the present application, the association relationship between the DCI and the first measurement resource set or the first trigger signaling can be implicitly indicated by the above-mentioned specific DCI format (default DCI format).

[0200] Optionally, the method of the embodiment of the present application further includes:

[0201] Configure the first measurement resource set associated with the first trigger signaling.

[0202] The beam processing method of the present application is described below in conjunction with embodiments.

[0203] Embodiment 1:

[0204] 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.

[0205] 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 measurement 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:

[0206]

[0207]

[0208]

[0209] Configure one or more sub - resource sets in the measurement resource set. Each resource sub - set corresponds to one of the beams output by the AI / ML model / function, and the resources within each resource sub - set use the same downlink spatial filter. That is to say, the measurement resource set for the AI / ML model output beam is a three - layer configuration. The first layer is the configured resource set for beam measurement based on the AI / ML model output. The second layer is different resource sub - sets within the configured resource set for carrying different output beams. The third layer is different resources within the configured resource sub - set for receiving beam scanning. The configuration method of the resource set for AI / ML model output beam measurement is as follows:

[0210]

[0211] After the base station triggers the measurement of the resources for 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 receiving beam scanning, and store the receiving beam with the highest RSRP corresponding to each resource sub - set, or store the receiving beam with the highest RSRP corresponding to the resource set.

[0212] Optionally, whether the beams in each sub - set use the same downlink filter can be configured based on a 1 - bit switch. For example, one state represents that the beams in the sub - set use the same downlink filter, and the other state represents that there is no need to use the same downlink filter within the sub - set. That is, whether to use the same downlink filter is configured at the sub - set granularity. An optional configuration method is as follows:

[0213]

[0214] Optionally, the configuration method of the number of resource sub - sets in a resource set is as follows:

[0215] 1) If the measurement resource set has a one - to - one association with the 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.

[0216] 2) If the resource set has a one - to - many association with the AI / ML model / function, the number of sub - resource sets is the same as the maximum value of the number of output beams of the AI / ML model / function.

[0217] Optionally, the number of resources in a resource subset is the same as the number of receiving beams of the terminal.

[0218] Embodiment 2:

[0219] In this embodiment, after the base station triggers the aperiodic measurement report for the measurement resource set corresponding to the AI / ML model / function, the base station will send the reference signal using the beam inferred by the latest AI / ML model / function on the measurement resource. The terminal performs the measurement of L1-RSRP on each measurement resource, that is, performs the measurement on the beam inferred by the AI / ML model / function, and caches the optimal receiving beam corresponding to each resource subset in the resource set. The base station then notifies the terminal of the beam numbers of the triggered / measured beams later. After that, the base station can indicate to the terminal, in the manner of TCI / QCL indication, to send the downlink signal / channel using the beam inferred by AI / ML. Since the terminal has cached the optimal receiving beam corresponding to the beam inferred by AI / ML, the optimal receiving beam can be used for receiving the downlink signal / channel based on the implementation.

[0220] Taking the example that the base station triggers the aperiodic measurement for the resource set with ID = 1 corresponding to the AI / ML model / function at two times T1 and T2 respectively, T1 is the earlier time and T2 is the later time in terms of time. And the optimal beam inferred based on the AI / ML model most recently before T1 is the beam with ID = 16, and the optimal beam inferred based on the AI / ML model most recently before T2 is the beam with ID = 64.

[0221] Time T1:

[0222] Base station side

[0223] Step 1: The base station sends an aperiodic measurement trigger signaling (i.e., the above-mentioned first trigger signaling) at time T1, and this signaling is used to trigger the aperiodic measurement for the resource set with ID = 1 corresponding to the AI / ML model / function (i.e., the first measurement resource set).

[0224] Step 2: Since the optimal beam inferred based on the AI / ML model / function most recently before T1 is the beam with ID = 16. The base station sends the reference signal in the beam direction with beam ID = 16 on the triggered resource set, and this reference signal can be a CSI-RS signal.

[0225] Step 3: The base station indicates the ID = 16 or CSI-RS ID corresponding to this beam direction later, that is, sends the identifier corresponding to the triggered beam.

[0226] Terminal side

[0227] Step 1: The terminal receives an aperiodic measurement trigger signaling at time T1.

[0228] Step 2: The terminal measures the reference signal in a receive beam scanning manner on the triggered resource set based on the configuration. The terminal caches the receive beam corresponding to the highest L1-RSRP as the optimal receive beam of the measurement beam, such as RX1.

[0229] Step 3: The terminal subsequently receives the identifier corresponding to the measured beam manner, such as beam ID = 16, or CSI-RS ID, etc.

[0230] After that, the base station can indicate to the terminal to use beam / CSI-RS ID = 16 to transmit the downlink signal / channel through the TCI / QCL indication, and the terminal can receive it using the optimal receive beam RX1.

[0231] Time T2:

[0232] Base station side

[0233] Step 1: The base station sends an aperiodic measurement trigger signaling (i.e., the above first trigger signaling) at time T2, and this signaling is used to trigger the aperiodic measurement on the resource set corresponding to the AI / ML model / function with ID = 1.

[0234] Step 2: Since the optimal beam based on the AI / ML model / function inference closest to time T2 is the beam with ID = 64. The base station sends a reference signal in the beam direction with the numbered beam ID = 64 on the triggered resource set, and this reference signal can be a CSI-RS signal.

[0235] Step 3: The base station subsequently indicates the ID = 64 or CSI-RS ID corresponding to this beam direction, that is, sends the identifier number corresponding to the triggered beam.

[0236] Terminal side

[0237] Step 1: The terminal receives an aperiodic measurement trigger signaling at time T2.

[0238] Step 2: The terminal measures the reference signal in a receive beam scanning manner on the triggered resource set based on the configuration. The terminal caches the receive beam corresponding to the highest L1-RSRP as the optimal receive beam of the measurement beam, such as RX2.

[0239] Step 3: The terminal subsequently receives the identifier number corresponding to the measured beam manner, such as beam ID = 64, or CSI-RS ID, etc.

[0240] After that, the base station can indicate to the terminal, in the way of TCI / QCL indication, to use beam / CSI-RS ID = 64 for the transmission of downlink signals / channels, and the terminal can use the optimal receiving beam RX2 for reception.

[0241] Embodiment 3:

[0242] In this embodiment, after the base station transmits the reference signal using the beam inferred by the latest AI / ML model / function, the base station indicates the beam identification number or CSI-RS ID through the MAC CE signaling. The terminal obtains the optimal receiving beam corresponding to the downlink transmission beam based on the measurement of the reference signal, and then obtains the identification number or CSI-RS ID of each downlink transmission beam through the MAC CE. Each transmission beam identification number or CSI-RS ID corresponds to a TCI codepoint, and the base station can indicate, through the TCI field, to use the beam inferred by the AI / ML model / function for the transmission of downlink signals / channels.

[0243] Among them, the design method of the MAC CE includes the following:

[0244] Solution 1: The MAC CE includes the serving cell ID, the bandwidth part ID (BWP ID), and one or more beam numbers or CSI-RS IDs. Among them, each beam number or CSI-RS ID corresponds one-to-one with each sub-resource set in Embodiment 1, and the correspondence is in ascending / descending order of the sub-resource set ID. 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. Specifically as Figure 4 shown.

[0245] The association relationship between the information carried by the MAC CE and the first measurement resource set:

[0246] Solution 1-1: The information carried by the MAC CE is associated with the measurement resources in the first measurement resource set that is the closest in time domain before receiving the MAC CE or the triggering signaling that is the closest in time domain.

[0247] Solution 1-2: There is a time window T after the aperiodic measurement triggering signaling, and the received MAC CE within the time window T is associated with this aperiodic measurement triggering signaling.

[0248] Solution 1-3: By default, this MAC CE is sent within M downlink time slots after the aperiodic measurement triggering signaling, and the value of M can be a default value / dynamically indicated / high-layer configured.

[0249] 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, such as Figure 5 shown. Compared with Solution 1, the "time slot relationship K with the aperiodic measurement trigger signaling" is added to explicitly indicate the time slot interval between this MAC CE and the aperiodic measurement signaling. For example, when K = 16 in the MAC CE, assuming the MAC CE is in time slot n, the time slot where the aperiodic measurement trigger signaling associated with the MAC CE is located is n - K.

[0250] Solution 2-1: The MAC CE / DCI contains a measurement resource set identifier, a trigger signaling identifier, or an AI / ML model ID, explicitly indicating the association relationship between the MAC CE / DCI and the measurement resource set, the trigger signaling, or the AI / ML model.

[0251] Solution 3: Based on Solution 1 and Solution 2, the MAC CE also carries the TCI codepoint corresponding to each beam number / CSI-RS ID, such as Figure 6 shown. When the base station sends a MAC CE carrying one or more beam numbers / CSI-RS IDs and the corresponding TCI codepoints, the beam numbers / CSI-RS IDs with the indicated TCI codepoints are considered to be in the active state. The base station can indicate the downlink signal or channel through this TCI codepoint.

[0252] Embodiment 4:

[0253] 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:

[0254] Solution 1: This DCI format 1_1 / 1_2 is scrambled by 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, NDI = 1. Multiple fields in the TCI indication field, MCS indication field, Antenna port indication field, DMRS field, or other fields in the DCI form a bitmap to indicate one or more beam numbers or CSI-RS IDs. Among them, the bit length and position occupied by each beam number or CSI-RS in the bitmap are configured by the higher layer.

[0255] Solution 2: This DCI format 1_1 / 1_2 is scrambled by CS-RNTI, the FDRA field is set to all '0's or all '1's, MCS cannot be set to all 1's, RV = 0, NDI = 1. The method for indicating the beam number or CSI-RS ID is the same as that in Solution 1.

[0256] Solution 3: This DCI format 1_1 / 1_2 is scrambled by CS-RNTI, the FDRA field is set to all '0's or all '1's, MCS cannot be set to all 1's, RV = 0, NDI = 0. The method for indicating the beam number or CSI-RS ID is the same as that in Solution 1.

[0257] Solution 4: This DCI format 1_1 / 1_2 is scrambled by CS-RNTI, the FDRA field is set to all '0's or all '1's, MCS is set to all 0's, RV = 0. The NDI field is added to the available bit field, and the other methods for indicating the beam number or CSI-RS ID are the same as those in Solution 1.

[0258] As an alternative solution, the associated first resource ID or the time slot relationship with the aperiodic measurement trigger signaling can be explicitly indicated using a bit map. Or refer to the relationship between the DCI and the first resource set for measurement within a fixed time window, after M slots, or after the most recent aperiodic measurement trigger signaling.

[0259] The solution of the embodiments of the present application enables the network to use limited trigger states to instruct the terminal to perform measurements on any reference signal to obtain the optimal receiving beam, and further instruct the terminal of its corresponding reference signal identifier for QCL / TCI state indication during transmission.
