[0056] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application are further described in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0058] The terms "first / second / third" used in this application are merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0060] In related technologies, multi-TRP transmission can improve communication coverage, throughput for cell edge users, and transmission reliability. Multi-TRP scenarios can be implemented through joint transmission (JT) for cooperative TRP transmission, or through diversity transmission.

[0061] When the terminal is in multi-TRP transmission mode, the Channel State Information-Reference Signal (CSI-RS) is transmitted between multiple TRPs. In order to obtain an accurate channel, the terminal needs to measure the corresponding channel between multiple TRPs through different pilots. The pilot overhead is large, which leads to a reduction in spectral efficiency.

[0062] Embodiments of this application provide a channel pilot configuration method, applied to network devices, with reference to... Figure 1 As shown, the method includes the following steps:

[0063] Step S101: Receive the first message sent by the terminal.

[0064] The first message includes the number of N transceiver nodes of the access network device, the channel quality information of each of the N transceiver nodes, and the channel requirement information of the terminal; N is a positive integer.

[0065] Understandably, network equipment can be understood as a base station. Channel quality information may include, but is not limited to, the signal-to-noise ratio (SNR). Channel requirement information includes, but is not limited to, the terminal's channel accuracy requirements. Accuracy requirements can be set according to actual conditions, and this application does not impose specific limitations on them. For example, accuracy requirements can be set to high accuracy and other accuracies, where high accuracy can be represented as 1 and other accuracies as 0.

[0066] In practical applications, after a terminal accesses the network and enters the Radio Resource Control Connected (RRC-CONNECTED) state, the base station coordinates the transmission of the Channel State Information Reference Signal (CSI-RS). The terminal measures the channel corresponding to the access TRP and sends the first message to the base station.

[0067] Step S102: Send the second message to the terminal.

[0068] The second message includes the first configuration information of the first mode; in the first mode, the channel between the terminal and N transceiver nodes is measured through the same pilot.

[0069] Understandably, the first mode can be understood as a superimposed pilot mode.

[0070] In practical applications, before a terminal accesses the network, the base station can pre-collect downlink single TRP channel estimation data and downlink multiple TRP pilot superposition transmission channel estimation data for different TRPs, for reference. Figure 2 As shown, data from t1 to t7 within one period is collected. The data from t6 and t7 are used as training data for the prediction model's output, including pilot time-frequency positions and corresponding ports. The channel estimation time min{t1,t2,t3,t4,t5} on a single TRP needs to be less than the prediction time max{t6,t7} for offline training of the channel prediction model (denoted as P). i(i = 1, ..., N3), the channel prediction model can be deployed on the centralized unit (CU) and / or distributed unit (DU) on the base station side.

[0071] The channel prediction model can decompose the superimposed TRP channels into channels of different TRPs at times t6 and t7, as referenced. Figure 2 The predicted channel model shown can be synchronized from the base station to the terminal along with the predicted channel model and its corresponding model number. The actual number of TRPs accessing the base station may vary. The base station can collect different data based on the number of TRPs to train multiple different channel prediction models and synchronize them to the terminal.

[0072] The base station can configure relevant parameters based on the terminal's channel accuracy requirements. For example, these parameters may include a signal-to-noise ratio (SNR) threshold. Higher channel accuracy requirements mean fewer users can receive pilot overlay transmissions, and more single TRPs can be transmitted on the pilot within a single pilot configuration period. The base station configures whether to overlay pilots for different TRPs and the TRP numbers to be overlaid, based on the number of accessed TRPs and the channel quality measured by the terminal. If the TRP set uses pilot overlay transmission, first configuration information is sent via RRC signaling. This first configuration information may include the pilot transmission period, the number of single TRPs transmitted on the pilot within one period, the corresponding pilot positions for different TRPs, the number of overlaid TRPs transmitted on the pilot and their corresponding pilot positions, and the channel prediction model number. The terminal can then perform channel prediction based on the channel prediction model corresponding to the number.

[0073] The terminal collects channel data corresponding to the pilot (including channels of a single TRP and channels of multiple TRPs superimposed), completes channel estimation based on the pilot, and inputs the channel estimation data, corresponding time and channel time to be predicted into the channel prediction model corresponding to the model number to predict the channel at the required time.

[0074] The terminal measures the channel between different TRPs and the terminal using the same pilot signal, and performs channel prediction between different TRPs and the UE using an AI model. While maintaining the channel estimation accuracy, this can effectively reduce the number of pilot signals and improve spectrum efficiency.

[0075] The second message may also include second configuration information for the second mode, which can be understood as a non-superimposed pilot mode. The second configuration information can be configured according to existing protocols, including but not limited to pilot position information. In other words, this application can also implement the scheme in related technologies where network devices send configuration information for a non-superimposed pilot mode to the terminal, enabling the channel between the terminal and the transceiver node to be measured using different pilots.

[0076] As can be seen from the above, in this embodiment of the application, after receiving the first message sent by the terminal through the network device, the first configuration information including the first mode is sent to the terminal, so that the channel between the terminal and N transceiver nodes is measured through the same pilot, thereby solving the problem that the related technology protocol only supports different pilots to measure the channel between different TRPs and the terminal, resulting in large pilot overhead and failure to improve spectrum efficiency.

[0077] In some embodiments of this application, the first configuration information includes one or more of the following:

[0078] The node number of each of the N transceiver nodes;

[0079] Pattern information for the first mode;

[0080] The cycle of the first mode;

[0081] Model number;

[0082] The sending order of each of the N transceiver nodes.

[0083] In practical applications, we will use N=2 as an example, assuming that the base station can support a maximum of one terminal accessing two TRPs simultaneously, and can support a maximum of two TRPs transmitting simultaneously. The two TRPs can be represented as TRP1 and TRP2. Bit=1 indicates single TRP pilot transmission, and bit=0 indicates simultaneous transmission of pilots from both TRPs. The simultaneous transmission modes support the two modes shown in Table 1:

[0084] model first group other group Combination form 1 111100 1100 111100

[1100] N1 2 11110 11110 11110

[11110] N2

[0085] Table 1

[0086] Wherein, []N represents repetition N times. When two TRPs send data to the same UE at the same time, in order to predict the channel of the two TRPs, since predicting the channel of one TRP requires two pre-pilot data, in this embodiment of the application, at least four single TRP pilot data are set in the first group.

[0087] For example, each mode contains a first group and multiple other groups. In existing protocols, periodic or semi-persistent transmission is configured in the Channel State Reference Information Resource Configuration (CSI-Resource Config). The periodicity and offset of the Non-Zero-Power Channel State Information Reference Signal (NZP-CSI-RS-Resource) can be configured with time slot periods. As shown in Table 1, the time slot period between modes (10) and (00) can be twice as large as the time slot period between (11). The larger time slot period of the pilot configuration can reduce the number of time-frequency resources configured for the pilot and improve spectrum efficiency.

[0088] Assume the downlink pilot occupies N slots in one time slot slot A symbol. Configuration mode i contains N. i There are N periods, therefore a group contains N. i ×N slot The location for inserting pilot signals. For example, in mode 1, N1×N is used for configuration. slot It must be an integer multiple of 6 + 4 × N1. The transmission format without superimposed pilot signals can be set to Mode 3. The mode information for the first mode includes information from Mode 1 and Mode 2, and may also include information from Mode 3.

[0089] Taking first group 111100 in mode 1 as an example, 1111 uses two TRPs to send in turn. During configuration, the TRP numbers can be bitmapped, for example, sequence numbers 0 and 1. The one with sequence number 0 is sent first, and this configuration is sent to the terminal.

[0090] The base station can set the signal-to-noise ratio (SNR) threshold according to the accuracy requirements of the terminal. The first set of SNR thresholds is δ. 11 and δ 12 δ 11 >δ 12 The second group's signal-to-noise ratio threshold is δ. 21 and δ 22 δ 21 >δ 22 .

[0091] When the terminal requires high precision, the signal-to-noise ratio (SNR) of TRP1 is denoted as SNR1, and the SNR of TRP2 is denoted as SNR2. When min(SNR1, SNR2) > δ 11 When using mode 1, if max(SNR1,SNR2)<δ 12The non-overlapping mode is adopted, denoted as Mode 3; Mode 2 is adopted in all other cases; when the UE's channel accuracy requirement is other accuracy, when min(SNR1,SNR2)>δ 21 When using mode 1, if max(SNR1,SNR2)<δ 22 The non-overlapping mode is used, i.e., mode 3; the rest use mode 2. Mode 1 is used, numbered 01; mode 2 is used, numbered 10; mode 3 is used, numbered 11.

[0092] Training data meeting the signal-to-noise ratio (SNR) requirements is collected based on the three modes supported by the base station, and a channel prediction model is trained. According to the two modes designed in Table 1, multiple channel data are collected under different SNR conditions. This requires collecting channel data from a single TRP and also collecting superimposed channel data from multiple TRPs. Training the channel prediction model in mode 2 for the first group and other groups requires collecting... Figure 2 The data shown is as intended; however, training the other group in mode 1 requires using the predicted data of the first group in mode 1 and the corresponding channel data on a single TRP as input data to train the channel prediction model. The channel overlay mode used during model inference must be consistent with the channel overlay mode used when collecting data and completing model training.

[0093] In some embodiments of this application, before sending the second message to the terminal, the following steps are included:

[0094] If N is greater than the first threshold, the mode information of the first mode is determined based on the channel quality information and the channel demand information.

[0095] In practical applications, the first threshold can be set according to the actual situation. This embodiment uses a first threshold of 1 as an example. When N is 1, there is no need to consider the case of superimposed pilot signals, and mode 3 can be selected. When N is greater than 1, the base station can determine the model number of the channel prediction model based on the number of TRPs, and determine the configuration information of the superimposed pilot signal mode based on the channel quality information and channel demand information provided by the terminal.

[0096] Embodiments of this application provide a channel pilot configuration method, applied to a terminal, with reference to... Figure 4 As shown, the method includes the following steps:

[0097] Step S401: Send the first message to the network device.

[0098] The first message includes the number of N transceiver nodes of the access network device, the channel quality information of each of the N transceiver nodes, and the channel requirement information of the terminal; N is a positive integer.

[0099] In practical applications, after a terminal accesses the network and enters the RRC-CONNECTED state, the base station coordinates the transmission of CSI-RS. The terminal measures the channel corresponding to the access TRP and sends the first message to the base station.

[0100] Step S402: Receive the second message sent by the network device.

[0101] The second message includes the first configuration information of the first mode; in the first mode, the channel between the terminal and N transceiver nodes is measured through the same pilot.

[0102] In practical applications, base stations can configure relevant parameters based on the channel accuracy requirements of the terminal. For example, these parameters may include a signal-to-noise ratio (SNR) threshold. Higher channel accuracy requirements mean fewer users can receive pilot overlay transmissions, and more single TRPs can be transmitted on the pilot within a single pilot configuration period. The network side configures whether to overlay pilots for different TRPs and the TRP numbers to be overlaid, based on the number of accessed TRPs and the channel quality measured by the terminal. If the TRP set uses pilot overlay transmission, first configuration information is sent via RRC signaling. This first configuration information may include the pilot transmission period, the number of single TRPs transmitted on the pilot within one period, the corresponding pilot positions for different TRPs, the number of overlaid TRPs transmitted on the pilot and their corresponding pilot positions, and the channel prediction model number. The terminal can then perform channel prediction based on the channel prediction model corresponding to the number.

[0103] The terminal collects channel data corresponding to the pilot (including channels of a single TRP and channels of multiple TRPs superimposed), completes channel estimation based on the pilot, and inputs the channel estimation data, corresponding time and channel time to be predicted into the channel prediction model corresponding to the model number to predict the channel at the required time.

[0104] The terminal measures the channel between different TRPs and the terminal using the same pilot signal, and performs channel prediction between different TRPs and the UE using an AI model. While maintaining the channel estimation accuracy, this can effectively reduce the number of pilot signals and improve spectrum efficiency.

[0105] As can be seen from the above, in this embodiment of the application, after receiving the first message sent by the terminal through the network device, the first configuration information including the first mode is sent to the terminal, so that the channel between the terminal and N transceiver nodes is measured through the same pilot, thereby solving the problem that the related technology protocol only supports different pilots to measure the channel between different TRPs and the terminal, resulting in large pilot overhead and failure to improve spectrum efficiency.

[0106] In some embodiments of this application, the first configuration information includes one or more of the following:

[0107] The node number of each of the N transceiver nodes;

[0108] Pattern information for the first mode;

[0109] The cycle of the first mode;

[0110] Model number;

[0111] The sending order of each of the N transceiver nodes.

[0112] In practical applications, the content of the first configuration information can be referenced from the aforementioned steps, and will not be repeated here.

[0113] In some embodiments of this application, before sending the first message to the network device, the following steps are included:

[0114] Obtain the channel prediction model; the channel prediction model is used to predict the channel of the transceiver node in the first mode.

[0115] In practical applications, before a terminal accesses the network, the base station can pre-collect downlink channel estimation data for a single TRP and channel estimation data for multiple downlink TRPs transmitted via pilot overlay. This data is used for offline training of the channel prediction model, which can be deployed on the CU and / or DU at the base station. The base station can synchronize the channel prediction model and its corresponding model number to the terminal. The actual number of TRPs accessing the base station may vary, allowing the base station to collect different data based on the number of TRPs, train multiple different channel prediction models, and synchronize them to the terminal.

[0116] In some embodiments of this application, after receiving the first configuration information sent by the network device, the process includes:

[0117] Based on the first configuration information, channel data of each of the N transceiver nodes under different pilot frequencies and superimposed channel data of the N transceiver nodes under the same pilot frequency are collected.

[0118] Channel estimation is performed based on channel data and superimposed channel data to obtain channel estimation data;

[0119] Obtain correlation information from the channel estimation data; the correlation information includes the target channel time.

[0120] The channel estimation information and correlation information are input into the channel prediction model corresponding to the model number to obtain the predicted channel; the predicted channel indicates the channel corresponding to the target channel time for each of the N transceiver nodes.

[0121] In practical applications, we will use N=2 as an example, assuming that the base station can support a maximum of one terminal accessing two TRPs simultaneously, and can support a maximum of two TRPs transmitting simultaneously. The two TRPs can be represented as TRP1 and TRP2.

[0122] When the terminal requires high precision, the signal-to-noise ratio (SNR) of TRP1 is denoted as SNR1, and the SNR of TRP2 is denoted as SNR2. When min(SNR1, SNR2) > δ 11 When using mode 1, if max(SNR1,SNR2)<δ 12 The non-overlapping mode (mode 3) is used; mode 2 is used in all other cases; when the UE's channel accuracy requirement is other accuracy, when min(SNR1,SNR2)>δ 21 When using mode 1, if max(SNR1,SNR2)<δ 22 The non-overlapping mode is used, i.e., mode 3; the rest use mode 2. Mode 1 is used, numbered 01; mode 2 is used, numbered 10; mode 3 is used, numbered 11.

[0123] If mode 1 or 2 is selected, pilot signals for different TRPs are configured and transmitted according to mode 1 or 2, and the corresponding pilot signals are transmitted according to the configuration. The terminal receives the first configuration information of the superimposed pilot signal mode sent by the base station, collects the channel data corresponding to the pilot signals (including the channel of a single TRP and the channel of two superimposed TRPs), completes channel estimation based on the pilot signals, and inputs the channel estimation data, corresponding time and other relevant information, as well as the channel time to be predicted, into the corresponding channel prediction model to predict the channel at the required time. The target channel time can be understood as the channel time to be predicted.

[0124] The base station updates its configuration based on changes in the access TRP and channel accuracy requirements. It can update the pilot transmission configuration information by sending different mode numbers and model numbers. The configuration information includes: whether the pilots of different TRPs are transmitted in superposition, the order of transmitting a single TRP on the pilot within one cycle and the corresponding position of the pilot, and the corresponding position of superposition TRPs transmitted on the pilot within one cycle.

[0125] In a feasible scenario, refer to Figure 5 As shown, the channel pilot configuration method of this application embodiment can be implemented in the following way:

[0126] Step S501: Collect channel data of a single TRP and superimposed channel data of multiple TRPs, train an AI-based channel prediction model offline, synchronize the channel prediction model, model number, and transmission mode configuration to the terminal, and synchronize the model number and transmission mode configuration to the base station.

[0127] Step S502: The terminal has been connected to the network and enters RRC-CONNECTED.

[0128] Step S503: The base station coordinates access TRP to send CSI-RS.

[0129] Step S504: The terminal measures and reports the channel corresponding to the access TRP.

[0130] Step S505: Configure pilot parameters according to terminal requirements, the number of accessed TRPs, and reported channel quality. Configure whether pilots for different TRPs are overlaid, the TRP number for overlaid transmission, and related configurations for pilot overlay transmission. If TRP overlay transmission is used, proceed to step S506; if TRP non-overlay transmission is used, proceed to step S507. Send the pilot configuration and send the corresponding pilots according to the configuration.

[0131] Step S506: Terminal channel estimation, using an AI model to complete the superimposed channel prediction.

[0132] Step S507: The network side updates the pilot transmission configuration according to the changes in access TRP and channel accuracy requirements. For details, please refer to steps S503-S506.
