Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method, device and storage medium. Background Art

[0002] Currently, artificial intelligence (AI / ML)-based beam management requires the terminal / user equipment (UE) to report X layer 1 reference signal received powers (L1-RSRP) and corresponding X reference signal indexes to the network device, or to report the optimal K (Top-K) beams / beam pairs obtained through model reasoning.

[0003] In order to reduce the feedback overhead of the UE, there is a solution that the UE can report only the L1-RSRP of some beams / beam pairs, or reduce the number of the best beams / beam pairs reported. That is, X and K are configured by the base station and can be configured to smaller values.

[0101] In the New Radio (NR) system, in order to combat the path loss in high-frequency scenarios, the transmitter and receiver obtain matching beam pairs through beam management (BM) to improve beamforming gain. In the relevant downlink beam management process, the base station needs to cyclically send the transmit beam (Tx beam) in different directions, and the UE uses the receive beam (Rx beam) to receive the Tx beam, and measures the Channel State Information-Reference Signal (CSI-RS) / Synchronization Signal Block (SSB) signals sent on all Tx beams, selects the X beams (X=1,2,4) with the best reception performance (such as L1-RSRP), and reports the reference signal index information corresponding to these X beams to the base station. The base station selects the appropriate Tx beam for subsequent communication based on the information reported by the UE, and indicates the selected beam information to the UE.

[0102] In order to obtain the optimal beam pair, the base station needs to send CSI-RS / SSB on all Tx beams, which consumes a lot of reference signal resources. At the same time, the UE needs to use all Rx beams to measure the CSI-RS / SSB sent on all Tx beams respectively, which has a large measurement overhead. In order to solve these problems, it is proposed to use artificial intelligence (AI / ML) technology. Based on the measurement of some beams / beam pairs or historical beam / beam pair measurement results, the optimal beam / beam pair can be predicted, thereby saving reference signal (RS) transmission resources, UE measurement overhead and UE measurement delay.

[0103] Model training / model reasoning / model monitoring / model update can be done on the base station side or on the UE side. If the model reasoning is on the base station side, the UE needs to report the measured beam / beam pair quality (such as L1-RSRP) to the base station as the model input. If the model training / update is on the base station side, in addition to reporting the measured beam / beam pair quality, the UE also needs to report the label information used for model training. The label information can be the Top-K beam / beam pair indexes or the predicted L1-RSRP of the beam / beam pair set. When the number of reported beams / beam pairs and corresponding L1-RSRPs is large, the reporting overhead is large. If the model reasoning is on the UE side, the UE needs to report the predicted Top-K beam / beam pair indexes based on the reasoning results.

[0104] AI / ML-based beam management is one of the research use cases of the air interface AI / ML topic. Currently, the following two sub-use cases are used as sub-use cases of AI / ML beam management:

[0105] BM-case1: Spatial beam prediction, that is, predicting the Top-K beams / beam pairs in SetA based on SetB measured at a certain moment;

[0106] BM-case2: Time domain beam prediction, that is, predicting the Top-K beams / beam pairs of SetA at the next N' moments based on SetB measured at the historical N moments.

[0107] Among them, SetB and SetA can be a set consisting of a downlink transmit beam (DL Tx beam) or a set consisting of a transmit-receive beam pair (Tx-Rx beam pair). In the downlink transmit beam prediction, the UE fixes or selects a best Rxbeam, measures the Reference Signal Receiving Power (RSRP) of part of the DL Tx beam (SetB) sent by the base station, and the base station or UE predicts the Txbeam corresponding to the Top-K RSRP in SetA based on the measurement result of SetB, which is the Top-K downlink transmit beam prediction. In the transmit-receive beam pair prediction, a Tx beam of the base station and an Rxbeam of the UE form a beam pair (beam pair), and the UE measures the RSRP of the beam pair in SetB. The base station or UE predicts the beam pair corresponding to the Top-K RSRP in SetA based on the measurement result of SetB, which is the Top-K transmit-receive beam pair prediction. The output of the AI / ML model can be the ID of the predicted Top-K beam pairs of SetA, or the RSRP of the predicted beam pairs of SetA. The latter can select the Top-K beam pairs based on the size of the predicted RSRP. SetB can be a subset of SetA or not (e.g., SetB is a wide beam and SetA is a narrow beam).

[0108] The method of reporting L1-RSRP in the relevant channel state information (CSI) reporting scheme is as follows: the base station configures the UE with a measurement reference signal and the number of reported reference signals X (X=1 / 2 / 4), and the UE reports the L1-RSRP of the X reference signals in a differential manner (the maximum L1-RSRP uses 7 bits (bits), and the remaining L1-RSRPs use 4 bits) and the reference signal index corresponding to each L1-RSRP.

[0109] The above-mentioned method of reporting the L1-RSRP of the reference signal is to report X L1-RSRPs and the corresponding X reference signal indexes. Since X is configured by the base station, the overhead of each report is determined. For beam management based on AI / ML models, on the one hand, if the model is trained on the network side, the network equipment needs to obtain the L1-RSRP of all beams / beam pairs in SetB, or the L1-RSRP of all beams / beam pairs in SetA and SetB. In order to reduce the feedback overhead of the UE, there is a scheme that proposes that the UE only reports the L1-RSRP of some beams / beam pairs, and the number of reports is configured by the network side. When the channel environment is different, the quality of the beam pairs between the UE and the base station will also change. For example, most of the beam pairs measured at time 1 are of good quality, and most of the beam pairs measured at time 2 are of poor quality. If the base station is used to configure the reporting number, in some cases, the UE may only report some beams with better quality due to a small reporting number configured by the base station. In other cases, the base station may configure a large reporting number, and in addition to beams with better quality, some beams with poorer quality are also reported, resulting in poor performance of AI / ML model training.

[0110] On the other hand, if the model inference is on the UE side, the UE needs to report the information of the Top-K beams / beam pairs obtained by inference to the base station. In order to improve the accuracy of obtaining the optimal beam, after the base station receives the information of the Top-K beams reported by the UE, it can scan these K beams / beam pairs. After measuring these K beams / beam pairs, the UE reports the optimal beam / beam pair to the base station. If a classification model is used on the UE side, the AI / ML model output on the UE side is the confidence (i.e., probability) that each beam / beam pair is the optimal beam / beam pair in SetA. In different channel environments, the L1-RSRP value of SetB is different, and the probability obtained by each inference is also different. If the K optimal beams / beam pairs reported by the UE after model inference are fixed, it may happen that the probability of some beams / beam pairs is higher in some cases, and there is no need to report the indexes of other beams / beam pairs with lower probabilities, that is, K is set too large. In other cases, the probabilities of many beams / beam pairs may be close, and K may be set too small. Whether K is set too large or too small, the accuracy of the optimal beam / beam pair obtained based on the AI / ML model will be reduced, making the performance of the AI / ML model worse.

[0111] Based on the above technical problems, the embodiments of the present application set reporting conditions. For example, the UE can report the beam quality with better conditions (such as L1-RSRP is greater than or equal to a certain threshold). Under this reporting rule, the number of L1-RSRPs or indexes that meet the reporting conditions (such as greater than or equal to the threshold) is variable. By reasonably splitting the L1-RSRP reporting content, it is avoided that the base station does not know the quality of the beam reported by the UE or the number of bits required for reporting in advance and cannot demodulate, thereby taking into account the training performance and reporting overhead of the AI / ML model.

[0112] In addition, for model reasoning on the UE side, the number of predicted optimal beams / beam pairs to be reported is determined based on the UE reasoning situation. For example, the indexes of the beams whose sum of confidences obtained by model reasoning is greater than or equal to the threshold are arranged in descending order of confidence. At this time, the number of beams / beam pairs that meet the reporting conditions obtained by each reasoning is variable, and the L1-RSRP reporting content is then reasonably split to avoid the base station not knowing the quality of the beam reported by the UE or the number of bits required for reporting in advance and being unable to demodulate, thereby taking into account the accuracy and reporting overhead of the optimal beam / beam pair obtained based on the AI / ML model.

[0113] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0114] Figure 1 is one of the flow charts of the information transmission method provided in the embodiment of the present application, such as Figure 1 As shown, the embodiment of the present application provides an information transmission method, the execution subject of which may be a terminal, such as a mobile phone, etc. The method includes:

[0115] Step 101: Determine reporting information that meets reporting conditions; the reporting information is used for training an artificial intelligence model or for determining the optimal beam / beam pair for transmitting a signal.

[0116] Specifically, in an embodiment of the present application, the UE first determines the reporting information that meets the reporting conditions.

[0117] The reporting condition may be pre-agreed by the protocol or configured by the network device. The network device in the embodiment of the present application may be an access network device, such as a base station, or a core network device, such as an access and mobility management function (AMF) network element.

[0118] In different application scenarios, the content of the reported information may be different.

[0119] For example, in the case of model training on the network side, the reported information includes the quality and index of the reference signal that meets the reporting conditions, and the reported information is used for the training of the artificial intelligence model.

[0120] For example, in the case of model reasoning on the UE side, the reporting information includes the index of the beam / beam pair that meets the reporting conditions obtained through model reasoning, and the reporting information is used to determine the beam / beam pair that is optimal for transmitting the signal.

[0121] Step 102: Split the reported information into a first part of information and a second part of information and send the second part of information to a network device.

[0122] Specifically, in an embodiment of the present application, after the terminal determines that the reporting information meets the reporting conditions, the reporting information is split into a first part of information (part1) and a second part of information (part2), and the split part1 and part2 are sent to the network device.

[0123] For example, part 1 may occupy a fixed number of bits, and the content of part 1 determines the number of bits occupied by part 2. The network device may determine the number of bits of part 2 based on the content of part 1. When both part 1 and part 2 are reported through the Physical Uplink Control Channel (PUCCH) resources, the UE determines the number of bits to report part 2 based on the referenced part 2 reporting content to ensure that the network device and the UE are consistent in determining the PUCCH resources for transmitting the reporting information, wherein the referenced part 2 reporting content is configured by the network side or specified by the protocol.

[0124] For example, part 1 may occupy a fixed number of bits, and the number of bits occupied by part 2 may be reported to the network device through other information to ensure that the network device and the UE consistently determine the PUCCH resources for transmitting the reporting information.

[0125] For example, part 1 and part 2 may use the same transmission code rate.

[0126] For example, part 1 and part 2 may use different transmission code rates, part 1 may use a fixed transmission code rate, and the network device determines the transmission code rate of part 2 according to the content of part 1.

[0127] The information transmission method provided in the embodiment of the present application, when reporting information related to the artificial intelligence model, splits the reported information that meets the reporting conditions into a first part of information and a second part of information and sends the information to a network device, thereby reducing the feedback overhead of the UE and ensuring the performance of the artificial intelligence model.

[0128] In some embodiments, the first portion of information occupies a fixed number of bits; the content of the first portion of information determines the number of bits occupied by the second portion of information.

[0129] Specifically, in the embodiment of the present application, part 1 occupies a fixed number of bits, and the content of part 1 determines the number of bits occupied by part 2.

[0130] The network device determines the number of bits of part 2 according to the content of part 1. When both part 1 and part 2 are reported through PUCCH resources, the network device determines the number of bits of part 2 according to the referenced reported content of part 2 to ensure that the network device and the UE determine the same PUCCH resources for transmitting the reported information.

[0131] In the information transmission method provided in the embodiment of the present application, part 1 occupies a fixed number of bits, and the content of part 1 determines the number of bits occupied by part 2, thereby further reducing the feedback overhead while ensuring the performance of the artificial intelligence model.

[0132] In some embodiments, when the reported information is used for training an artificial intelligence model, the reported information includes the quality and index of a reference signal that meets the reporting conditions.

[0133] Specifically, in an embodiment of the present application, the reported information is used for training an artificial intelligence model, and the reported information includes the quality and index of a reference signal that meets the reporting conditions.

[0134] After the network device obtains the quality and index of the reference signal that meets the reporting conditions, it determines the training samples for model training based on the quality and index of the reference signal that meets the reporting conditions, and uses the training samples to train the artificial intelligence model.

[0135] For example, the UE may only report the L1-RSRP and index that meet the conditions. In the model training phase, the reporting condition of L1-RSRP is greater than or equal to a threshold Threshold 1, and Threshold 1 may be configured by the network side or specified by the protocol.

[0136] If the input of the model is the RSRP of the beam / beam pair of SetB, and the output of the model is the predicted ID of the Top-K beam / beam pair of SetA, then during training, the RSRP of the beam / beam pair of SetB whose RSRP is lower than the threshold Threshold1 is set to 0, and the RSRP of SetB is used as the model input for training.

[0137] If the input of the model is the RSRP of the beam / beam pair of SetB, and the output of the model is the predicted RSRP of the beam / beam pair of SetA, then during training, the RSRP of SetB after the RSRP of the beam / beam pair whose RSRP is lower than the threshold Threshold1 is set to 0 is used as the model input, and the RSRP of SetA after the RSRP of the beam / beam pair whose RSRP is lower than the threshold Threshold1 is set to 0 is used as the training label for model training.

[0138] In the model inference phase, if the network side performs model inference, the UE reports the reference signal index and corresponding L1-RSRP corresponding to SetB where the L1-RSRP is greater than or equal to the threshold. The base station performs inference based on the L1-RSRP reported by the UE and sets the L1-RSRP of the beam / beam pair in SetB that the UE does not report to 0 as the model input. If the UE side performs model inference, the UE reports the index value that meets the conditions after model inference, and the index value is used to represent the beam / beam pair in the SetA set.

[0139] The information transmission method provided in the embodiment of the present application, when the reported information is used for training an artificial intelligence model, the reported information includes the quality and index of the reference signal that meets the reporting conditions, thereby ensuring the performance of the artificial intelligence model training.

[0140] In some embodiments, the reference signal satisfying the reporting condition includes a reference signal whose corresponding L1-RSRP is greater than or equal to a first threshold.

[0141] Specifically, in the embodiment of the present application, the reference signal that meets the reporting condition includes a reference signal whose corresponding L1-RSRP is greater than or equal to a first threshold. For example, the reporting condition of L1-RSRP is greater than or equal to a threshold Threshold1, and Threshold1 can be configured by the network side or specified by the protocol.

[0142] The information transmission method provided in the embodiment of the present application, the reference signal that meets the reporting conditions includes a reference signal whose corresponding L1-RSRP is greater than or equal to the first threshold, which reduces the feedback overhead of the UE and ensures the performance of the artificial intelligence model training.

[0143] In some embodiments, the first part of information includes the number of reference signals that meet the reporting conditions; the second part of information includes the quality and index of the reference signals that meet the reporting conditions.

[0144] Specifically, there are multiple ways to split the reporting information into part 1 and part 2. In an embodiment of the present application, part 1 includes the number of reference signals that meet the reporting conditions, and part 2 includes the quality and index of the reference signals that meet the reporting conditions.

[0145] The quality of the reference signal may be an L1-RSRP value of the reference signal and / or a difference value of the L1-RSRP of the reference signal.

[0146] For example, part 1 includes the number of reference signals N that meet the reporting conditions (or reported by part 2), and part 2 includes N L1-RSRPs and corresponding indexes. When reporting N RSRPs, differential reporting can be used to report the benchmark measurement value (for example, the maximum L1-RSRP measurement value) and the difference between the remaining N-1 RSRPs that meet the reporting conditions and the maximum L1-RSRP. Among them, the maximum L1-RSRP is quantized into L bits, and the differential L1-RSRP is quantized into X bits.

[0147] The number of bits occupied by UE reporting part1 is Wherein M is the number of reference signals measured by the user configured by the base station (for example, the number of reference signals corresponding to the beam / beam pair in SetB). When the UE determines the resource size for reporting part2, it is determined based on the reporting content of the reference part2. The reporting content of the reference part2 is to report S L1-RSRPs and the corresponding indexes, where the value of S is specified by the base station configuration or protocol.

[0148] The information transmission method provided in the embodiment of the present application, part 1 includes the number of reference signals that meet the reporting conditions, and part 2 includes the quality and index of the reference signals that meet the reporting conditions, which ensures that the network side knows the number of bits required for the information reported by the UE, thereby ensuring that the network side can successfully demodulate the information reported by the UE.

[0149] In some embodiments, the first part of information includes a bitmap of index mapping of reference signals that meet reporting conditions; and the second part of information includes the quality of reference signals corresponding to the index sequence of the reference signals mapped in the bitmap.

[0150] Specifically, there are multiple ways to split the reporting information into part 1 and part 2. In an embodiment of the present application, part 1 includes a bitmap of index mapping of reference signals that meet the reporting conditions, and part 2 includes the quality of the reference signals corresponding to the index order of the reference signals mapped in the bitmap.

[0151] For example, part 1 includes a bitmap, which is used to indicate which reference signals among the measured reference signals meet the reporting condition. The length of the bitmap is the number of measured reference signals. For example, if the i-th bit in the bitmap is 1, it indicates that the i-th reference signal among the measured reference signals meets the reporting condition, and if it is 0, it indicates that the reporting condition is not met.

[0152] In the case where the quality of the reference signal is the L1-RSRP value of the reference signal, part2 includes N L1-RSRPs that meet the reporting conditions corresponding to the index order of the reference signal mapped in the bitmap, each reported L1-RSRP is quantized into L bits, and the RSRP is sorted in the order of the reference signal index corresponding to the bit 1 in the bitmap. For example, the UE determines that the L1-RSRP of the 1st, 5th, and 7th reference signals in the measured reference signal is greater than or equal to the threshold based on the reference signal measurement result, and the UE determines that the reporting content of part1 is 10001010. If the L1-RSRP greater than or equal to the threshold is quantized into 7 bits, the UE quantizes the RSRP of the 1st, 5th, and 7th reference signals into 7 bits and maps them in sequence.

[0153] When the quality of the reference signal is the differential value of the L1-RSRP of the reference signal, part2 includes the index of N L1-RSRPs and the maximum L1-RSRP that meet the reporting conditions corresponding to the index order of the reference signal mapped in the bitmap, where the maximum L1-RSRP is quantized into L bits, and the difference between the remaining N-1 L1-RSRPs and the maximum L1-RSRP is quantized into X bits.

[0154] The number of bits occupied by the UE reporting part1 is M, where M is the number of reference signals measured by the user configured by the base station. When the UE determines the resource size for reporting part2, it is determined based on the referenced reporting content of part2. The referenced reporting content of part2 is to report S RSRPs, where the value of S is specified by the base station configuration or protocol.

[0155] The information transmission method provided in the embodiment of the present application, part 1 includes a bitmap of index mapping of reference signals that meet the reporting conditions, and part 2 includes the quality of the reference signal corresponding to the index order of the reference signal mapped in the bitmap, thereby ensuring that the network side knows the number of bits required for the information reported by the UE, thereby ensuring that the network side can successfully demodulate the information reported by the UE.

[0156] In some embodiments, the first part of information includes the quality and index of a part of the reference signals that meet the reporting conditions, and also includes the number of reference signals reported by the second part of information; the second part of information includes the quality and index of another part of the reference signals that meet the reporting conditions.

[0157] Specifically, there are multiple ways to split the reporting information into part 1 and part 2. In an embodiment of the present application, part 1 includes the quality and index of a part of the reference signals that meet the reporting conditions, and also includes the number of reference signals reported by part 2. Part 2 includes the quality and index of another part of the reference signals that meet the reporting conditions.

[0158] For example, part 1 includes L1-RSRP of N1 reference signals, corresponding N1 reference signal indexes, and N2, where N2 = N-N1. Part 2 reports N2 RSRPs and corresponding indexes, where N1 is configured by the network side.

[0159] When the quality of the reference signal is the L1-RSRP value of the reference signal, the UE reports the L1-RSRP and index of the fixed N1 reference signals in part 1, and reports the L1-RSRP and index of the remaining reference signals that meet the reporting conditions in part 2. If the number of reference signals that meet the reporting conditions N is less than N1, the UE reports the L1-RSRP and index of N reference signals in part 1, and the remaining N1-N L1-RSRPs are reported as special values ​​(such as all 0 or all 1).

[0160] When the quality of the reference signal is the differential value of the L1-RSRP of the reference signal, the L1-RSRP of the N1 reference signals reported by the UE is 1 maximum L1-RSRP and N1-1 differential L1-RSRP, and the L1-RSRP of the N2 reference signals is N2 differential L1-RSRP. The maximum L1-RSRP is quantized into L bits, and the differential L1-RSRP is the difference between the measured L1-RSRP and the maximum L1-RSRP, which is quantized into X bits.

[0161] The number of bits occupied by the UE reporting part 1 is the sum of the number of bits for reporting the L1-RSRP of N1 reference signals and the corresponding index. When the UE determines the resource size of the reported part2, it is determined according to the reported content of the referenced part2, where the reported content of the referenced part2 is to report W differential RSRPs and corresponding indexes, where the value of W is specified by the base station configuration or protocol.

[0162] The information transmission method provided in the embodiment of the present application, part 1 includes the quality and index of a part of the reference signals that meet the reporting conditions, and also includes the number of reference signals reported by part 2, and part 2 includes the quality and index of another part of the reference signals that meet the reporting conditions, which ensures that the network side knows the number of bits required for the information reported by the UE, thereby ensuring that the network side can successfully demodulate the information reported by the UE.

[0163] In some embodiments, the first part of information includes a bitmap of index mapping of reference signals that meet reporting conditions, and the quality of a part of reference signals corresponding to the index order of the reference signals mapped by the bitmap; the second part of information includes the quality of another part of reference signals corresponding to the index order of the reference signals mapped by the bitmap.

[0164] Specifically, there are multiple ways to split the reporting information into part 1 and part 2. In an embodiment of the present application, part 1 includes a bitmap of index mapping of reference signals that meet the reporting conditions, and the quality of a part of the reference signals corresponding to the index order of the reference signals mapped by the bitmap. Part 2 includes the quality of another part of the reference signals corresponding to the index order of the reference signals mapped by the bitmap.

[0165] For example, part1 includes the L1-RSRP of N1 reference signals, the index corresponding to the maximum RSRP and the bitmap, and part2 includes the L1-RSRP of N2 reference signals. Among them, the N1 L1-RSRP reported in part1 includes the maximum L1-RSRP quantized as L bits and N1-1 L1-RSRPs quantized as X bits that are differential from the maximum L1-RSRP. The N2 L1-RSRPs reported in part2 are the L1-RSRPs quantized as X bits that are differential from the maximum L1-RSRP. The differential L1-RSRPs reported in part1 and part2 are mapped according to the index order in the bitmap.

[0166] The number of bits occupied by the UE reporting part1 is the sum of the number of bits occupied by the L1-RSRP of the N1 reference signals, the index of the maximum RSRP, and the bitmap, where the number of bits for reporting the L1-RSRP of the N1 reference signals is L+X*(N1-1), and the number of bits for reporting the index of the maximum RSRP is The number of bits in the reporting bitmap is M, where M is the number of reference signals measured by the user configured by the base station. When the UE determines the resource size for reporting part 2, it is determined based on the reported content of the referenced part 2, where the reported content of the referenced part 2 is to report W differential RSRPs, where the value of W is specified by the base station configuration or protocol.

[0167] The information transmission method provided in the embodiment of the present application, part 1 includes a bitmap of index mapping of reference signals that meet the reporting conditions, and the quality of a part of the reference signals corresponding to the index order of the reference signals mapped by the bitmap, and part 2 includes the quality of another part of the reference signals corresponding to the index order of the reference signals mapped by the bitmap, which ensures that the network side knows the number of bits required for the information reported by the UE, thereby ensuring that the network side can successfully demodulate the information reported by the UE.

[0168] In some embodiments, the quality of the reference signal is an L1-RSRP value of the reference signal and / or a difference value of the L1-RSRP of the reference signal.

[0169] Specifically, in an embodiment of the present application, the qualities of the reference signals may all be L1-RSRP values ​​of the reference signals, may all be differential values ​​of the L1-RSRP of the reference signals, or may include both the L1-RSRP values ​​of a portion of the reference signals and the differential values ​​of the L1-RSRP of a portion of the reference signals.

[0170] In the case where the qualities of the reference signals are all L1-RSRP values ​​of the reference signals, the amount of calculation of the network device can be reduced.

[0171] In the case where the qualities of the reference signals are all differential values ​​of the L1-RSRP of the reference signals, the feedback overhead of the UE can be further reduced.

[0172] In some embodiments, when the reporting information is used to determine the optimal beam / beam pair for transmitting a signal, the reporting information includes an index of the beam / beam pair that meets the reporting condition obtained through model reasoning.

[0173] Specifically, in an embodiment of the present application, model inference is performed on the UE side. After model inference, the UE reports the index value of the beam / beam pair that meets the conditions. After the base station receives the information of the Top-K beams reported by the UE, it can scan these K beams / beam pairs. After measuring these K beams / beam pairs, the UE reports the optimal beam / beam pair to the base station.

[0174] For example, the UE side uses a classification model, and the AI / ML model output on the UE side is the confidence (i.e., probability) that each beam / beam pair is the optimal beam / beam pair in Set A. In different channel environments, the L1-RSRP value of Set B is different, and the probability obtained by each inference is also different.

[0175] In the information transmission method provided in the embodiment of the present application, the UE reports the index value of the beam / beam pair that meets the conditions after model reasoning, that is, the number of reported optimal beam / beam pair indexes is not fixed. In some cases, the probability of a few beams / beam pairs is high, and the number of reported beam / beam pair indexes is small. In other cases, the probabilities of more beams / beam pairs may be close, and the number of reported beam / beam pair indexes is large, thereby ensuring that the beam / beam pair received by the network device based on AI / ML model reasoning is more accurate, thereby ensuring the accuracy of the determined optimal beam / beam pair.

[0176] In some embodiments, the method further comprises:

[0177] Perform model inference based on the trained artificial intelligence model to determine the confidence level corresponding to each beam / beam pair output by the artificial intelligence model;

[0178] The index of the beam / beam pair that meets the reporting condition is determined based on the confidence corresponding to each beam / beam pair.

[0179] Specifically, in the embodiment of the present application, the classification model is adopted on the UE side, and the AI / ML model output on the UE side is the confidence (i.e., probability) that each beam / beam pair is the optimal beam / beam pair in Set A. In different channel environments, the L1-RSRP value of Set B is different, and the probability obtained by each inference is also different.

[0180] Before reporting the index of the beam / beam pair that meets the reporting conditions obtained through model reasoning, the UE also needs to perform model reasoning based on the trained AI / ML model to determine the confidence corresponding to each beam / beam pair output by the AI / ML model, and then determine the index of the beam / beam pair that meets the reporting conditions based on the confidence corresponding to each beam / beam pair.

[0181] The information transmission method provided in the embodiment of the present application performs model reasoning on the UE side, thereby improving the efficiency of beam management.

[0182] In some embodiments, the index of the beams / beam pairs that meet the reporting conditions includes the index corresponding to the beams / beam pairs whose total confidence is greater than or equal to the second threshold and whose number is the smallest.

[0183] Specifically, in an embodiment of the present application, the index of the beam / beam pair that meets the reporting conditions includes the index corresponding to the beam / beam pair with the smallest number and the sum of confidences greater than or equal to the second threshold Threshold2, and Threshold2 can be configured by the network side or specified by the protocol.

[0184] For example, when the UE performs model inference, the UE needs to determine the number of reported inference beam indexes K based on the above conditions. K is the minimum number of beams / beam pairs whose sum of confidences is greater than or equal to the threshold Threshold2. For example, assuming that SetA has 8 beams / beam pairs, and the confidence reporting threshold Threshold2 is set to 0.7, and the confidence output by the AI / ML model is [0.15, 0.3, 0.2, 0.15, 0.05, 0.05, 0.05, 0.05], the UE reports the indexes corresponding to the first 4 predicted beams (the sum of confidences is greater than or equal to the threshold). When the confidence output by the AI / ML model is [0.05, 0.5, 0.2, 0.05, 0.05, 0.05, 0.05, 0.05], the UE reports the indexes corresponding to the 2nd and 3rd predicted beams.

[0185] The information transmission method provided in the embodiment of the present application comprises an index of beams / beam pairs that meet the reporting conditions, including an index corresponding to beams / beam pairs whose total confidence is greater than or equal to a second threshold Threshold2 and whose number is the smallest, thereby ensuring that the beams / beam pairs received by the network device based on AI / ML model reasoning are more accurate, thereby ensuring the accuracy of the determined optimal beams / beam pairs.

[0186] In some embodiments, the first part of information includes the index of a part of the beams / beam pairs that meet the reporting conditions; the second part of information includes the index of another part of the beams / beam pairs that meet the reporting conditions.

[0187] Specifically, in an embodiment of the present application, when the UE reports the index of the beam / beam pair that meets the reporting conditions obtained through model reasoning, the reported content is split into part 1 and part 2.

[0188] For example, the splitting method is that part1 is K1 index values ​​and K2 values, where K2=(K-K1), and part2 is K2 index values, where K1 is configured by the base station.

[0189] When the UE determines the size of the reported resources, it is determined based on the number of bits occupied by part1 and the number of bits occupied by the reference part2 content. The reference part2 content is the resources occupied by reporting the indexes of R predicted beams / beam pairs, where R is configured by the base station or specified by the protocol.

[0190] The information transmission method provided in the embodiment of the present application, part 1 includes the index of a part of the beams / beam pairs in the beams / beam pairs that meet the reporting conditions, and part 2 includes the index of another part of the beams / beam pairs in the beams / beam pairs that meet the reporting conditions, which ensures that the network side knows the number of bits required for the information reported by the UE, thereby ensuring that the network side can successfully demodulate the information reported by the UE.

[0191] It should be noted that: when the index content of L1-RSRP or the inferred beam / beam pair is split in the above embodiment, if the number of bits occupied by the actually reported part2 is smaller than the number of bits occupied by the reference part2, the coding rate of the transmitted part2 is lower than the target code rate when the PUCCH transmits information; if the number of bits occupied by the actually reported part2 is greater than the number of bits occupied by the reference part2, the coding rate of part2 is greater than the target code rate when the PUCCH transmits information.

[0192] The method in the above embodiment is further described below with reference to several specific examples.

[0193] Example 1:

[0194] The base station configures the UE to measure 32 reference signals, corresponding to the 32 beam pairs of SetB. The base station configures the UE reporting threshold to be -100dBm, that is, the UE reports the reference signal quality with L1-RSRP greater than or equal to -100dBm to the base station. Assuming that the UE measures that the number of reference signals with L1-RSRP greater than or equal to -100dBm among the 32 reference signals is 8, the reporting content is shown in Table 1. Part 1 reports the number of reference signals that meet the conditions, and part 2 reports the reference signal indexes and corresponding L1-RSRPs that meet the reporting conditions. The maximum L1-RSRP is quantized to 7 bits, and the differential L1-RSRP is quantized to 4 bits.

[0195] Table 1

[0196]

[0197] Example 2:

[0198] The base station configures the UE to measure 32 reference signals, corresponding to the 32 beam pairs of SetB. The base station configures the UE to report a threshold of -100dBm, that is, the UE reports the quality of reference signals with L1-RSRP greater than or equal to -100dBm to the base station. The base station configures the UE to report 4 reference L1-RSRPs, the index corresponding to the maximum RSRP, and the bitmap in part1. Assuming that the UE measures 8 reference signals with L1-RSRP greater than or equal to -100dBm among the 32 reference signals, the reporting content is shown in Table 2. Part 1 reports the bitmap indicating the reference signals that meet the reporting conditions, the index of the maximum L1-RSRP, and the L1-RSRP of the 4 reference signals (1 maximum L1-RSR and 3 differential L1-RSRPs), and part 2 reports 4 differential L1-RSRPs that meet the reporting conditions, of which the maximum L1-RSRP is quantized to 7 bits and the differential L1-RSRP is quantized to 4 bits.

[0199] Table 2

[0200]

[0201] The differential L1-RSRP reported by the UE in Table 2 is reported in the order indicated by the bitmap in part 1. For example, the bitmap in Table 2 indicates that 8 of the 32 reference signals measured by the UE meet the reporting conditions, and indicates that the reference signal with the maximum L1-RSRP is the 4th reference signal. The other differential reference signals are mapped in sequence according to the order of the reference signal indexes indicated by the bitmap.

[0202] Example three:

[0203] When model inference is performed on the UE side and the confidence of the AI / ML model output is [0.15, 0.3, 0.2, 0.15, 0.05, 0.05, 0.05, 0.05]. The base station configures the inference result reported by the UE to be the index of the beam whose sum of confidence is greater than or equal to 0.7, and configures the UE to report 3 indexes in part1 and 2 indexes in the reference part2. According to the reporting conditions, the indexes of the beams corresponding to the first 4 confidences meet the conditions. The reported content is shown in Table 3. Part1 includes the indexes of the beams corresponding to the first 3 confidences and the value of K2 is 1; part2 includes the index of the beam corresponding to the 4th confidence. Since the number of bits of the actually transmitted part is less than the number of bits of the reference part2, the actual coding rate of part2 is less than the target bit rate.

[0204] Table 3

[0205]

[0206] The embodiments of the present application solve the problem of how the UE reports the L1-RSRP measurement results of some beams to the base station according to the reporting conditions when the base station side performs model training and model reasoning, so that the base station can perform operations such as model training / model reasoning for beam prediction in the spatial domain or time domain based on the AI / ML model, which not only reduces the reporting overhead but also ensures the performance of the AI ​​model; when the UE side performs model reasoning, the UE reports the reasoning results to the base station according to the reporting conditions, balancing the reporting overhead and the accuracy of obtaining the optimal beam.
