Description

TECHNICAL FIELD

[0001] The present application relates to the field of wireless technology, and particularly refers to an information prediction method and device, a network device and a node device. BACKGROUND

[0002] In a 4G Long Term Evolution (LTE) and 5G New Radio (NR) communication system, an Adaptive Modulation and Coding (AMC) technology is usually used to cope with the time-varying characteristics of a wireless channel to ensure the transmission quality of a wireless link. AMC is a technology that adaptively adjusts the modulation mode and coding rate of wireless link transmission according to the change of a wireless channel: when the channel quality is poor, a lower-order modulation and coding scheme (MCS) is selected, and when the channel quality is good, a higher-order MCS is selected, thereby maximizing the transmission efficiency of the wireless link while ensuring the transmission reliability of the wireless link.

[0003] Currently, an inner loop control and an outer loop control are usually used to select and adjust the MCS. In the inner loop control, a base station selects a suitable MCS value by table lookup based on the signal to interference plus noise ratio (SINR) information obtained by measuring the uplink reference signal; in the outer loop control, the base station adjusts the MCS value based on the cyclic redundancy check (CRC) success / failure of the decoded physical uplink shared channel (PUSCH) to slowly converge the block error rate (BLER) to the BLER target.

[0004] In the existing MCS selection method, the time when the base station measures the UL SINR is different from the time when the uplink PUSCH data service transmission is scheduled, and the channel quality has changed by several milliseconds. In the case of large interference fluctuation, the base station cannot select a suitable MCS according to the channel quality at the time when the uplink PUSCH data service transmission is scheduled, resulting in that the selected MCS cannot meet the high reliability and low latency transmission requirements of the wireless network transmission.

In the embodiment of the present application, optionally, the uplink interference in the time between the last reporting period and the current reporting period requested to be subscribed to is the average interference value in the time.

[0102] And / or, the subscription request is used for requesting to subscribe to the channel matrix of the terminal in the historical time (the last reporting period of the current reporting period, and / or the time between the last reporting period and the current reporting period). Wherein, the channel matrix is a K×M×P matrix, K is the number of operating frequency domain subcarriers of the terminal, P is the number of antennas of the terminal, and M is the number of antennas of the receiving end of the uplink reference signal sent by the terminal. In the embodiment of the present application, optionally, the channel matrix in the time between the last reporting period and the current reporting period requested to be subscribed to includes the sampling data of all channel matrices in the time.

[0103] In the embodiment of the present application, in another implementation, optionally, after obtaining the subscription request sent by the first network device, the first node (such as a base station) sends first information to the first network device through an interface connected with the first network device according to the subscription request, and the first information includes the measurement information requested to be subscribed to by the first network device, that is, the uplink interference and / or the channel matrix requested to be subscribed to.

[0104] Wherein, the first network device receives the first information sent by the first node according to the subscription request, including:

[0105] Receiving the first information sent by the first node to the first network device according to the subscription request by using the reporting mode; wherein, the first information includes the subscription content.

[0106] Specifically, the subscription content includes the uplink interference and / or the channel matrix.

[0107] Wherein, the subscription content in the first information includes the uplink interference value RIP received by each RB / RBG and / or the interference uplift value IOT received by each RB / RBG in a historical time (the last reporting period of the current reporting period, and / or the time between the last reporting period and the current reporting period) in the operating frequency band of the serving cell where the terminal is located. In the embodiment of the present application, optionally, in the subscription content included in the first information, the uplink interference in the time between the last reporting period and the current reporting period requested to be subscribed to is the average interference value in the time.

[0108] For example, the uplink interference in the first information includes RIP. In a historical time, the RIP received by each RB or RBG can be as shown in Table 1.

[0109] Table 1

[0110] RB or RBG number RIP 1 -70 2 -80 3 -85 … … M -76

[0111] In addition, the subscription content in the first information includes a channel matrix of the terminal in a historical time (the last reporting period of the current reporting period, and / or the time between the last reporting period and the current reporting period). The channel matrix is a KxMxP matrix, K is the number of frequency domain subcarriers of the terminal, P is the number of antennas of the terminal, and M is the number of antennas of the receiving end of the uplink reference signal sent by the terminal. In an embodiment of the application, optionally, in the subscription content included in the first information, the channel matrix of the time between the last reporting period and the current reporting period includes the sampling data of all channel matrices in the time.

[0112] In an embodiment of the application, the first network device determines the service transmission prediction information according to the first information sent by the first node to the first network device using the reporting mode.

[0113] According to the uplink interference, the first network device determines the uplink interference prediction value of the terminal scheduled by the first node at the first time; and / or, according to the channel matrix, the first network device determines the channel matrix prediction value of the terminal scheduled by the first node at the first time.

[0114] Specifically, the first network device performs data processing, model training, and model reasoning according to the uplink interference and / or the channel matrix in a preset historical time range reported by the first node, to generate the uplink interference prediction value and the channel prediction value.

[0115] When the first network device determines the uplink interference prediction value of the terminal scheduled by the first node at the first time according to the uplink interference, the uplink interference prediction can be realized based on an AI method.

[0116] Specifically, the first network device converts the uplink interference in the preset historical time range into a supervised learning data set, predicts the uplink interference at a future time, and obtains the uplink interference prediction value.

[0118] Table 2

[0119]

[0120] According to the T historical periods, the received RIPs of each transmission resource block in the working frequency band of the serving cell of the terminal can be used to determine the RIPs at the kth time (the first time) after the second time t, that is, the received RIPs of each transmission resource block in the working frequency band of the serving cell of the terminal, which can be shown in Table 3 as follows.

[0121] Table 3

[0122] RB or RBG number t+k 1 [RIP1(t+k)] 2 [RIP2(t+k)] … … M RIP M (t+k)

[0123] Specifically, the received RIPs of each transmission resource block in the working frequency band of the serving cell of the terminal in the T historical periods can be used as input (such as the data shown in Table 2), and an AI algorithm can be used to obtain the predicted uplink interference values of each transmission resource block when the terminal is scheduled at the first time by using the training and inference processes of the AI model, for example, the RIPs shown in Table 3.

[0124] Optionally, the AI algorithm includes, but is not limited to, only algorithms using distributed gradient enhancement library xgboost, long short-term memory (LSTM), time convolution network, etc.

[0125] In another implementation of the information prediction method described in the embodiments of the present application, the channel matrix prediction value of the first node when scheduling the terminal at the first time is determined according to the channel matrix, and the method comprises the following steps.

[0126] The channel matrices of the received uplink reference signals at the plurality of historical times are converted to obtain channel feature data of the received uplink reference signals at the plurality of historical times.

[0127] The channel feature prediction value of the first node when scheduling the terminal at the first time is obtained according to the channel feature data of the received uplink reference signals at the plurality of historical times.

[0128] The channel feature prediction value is inversely transformed to obtain the channel matrix prediction value of the first node when scheduling the terminal at the first time.

[0129] With the embodiment, the first node (base station) continuously monitors and records the received signal characteristics of the uplink reference signal sent by the scheduled terminal on the access carrier at each base station antenna, obtains historical channel data corresponding to the uplink reference signal sent by the terminal at a plurality of historical times before the second time, determines the channel matrix of the uplink reference signal received at the plurality of historical times, and sends the channel matrix of the plurality of historical times to the first network device, so that the first network device determines the channel matrix prediction value of the terminal scheduled by the first node at the first time according to the channel matrix of the plurality of historical times.

[0130] Specifically, the corresponding relationship between the received signal characteristics of the uplink reference signal sent by the base station scheduling terminal on the access carrier at each base station antenna and the channel matrix of the corresponding uplink reference signal can be represented by the following formula one:

[0131] Formula one:

[0132] Wherein, Y(k, r) is the channel data of the uplink reference signal received by the base station at the kth subcarrier on the rth antenna of the scheduled terminal; X(k, p) is the channel data of the uplink reference signal sent by the terminal at the kth subcarrier in the frequency domain and the pth antenna; the signal characteristics of the uplink reference signal sent by the terminal are configured to the terminal by the base station through high layer signaling and uplink outer loop power control; H(k, r, p) is the channel matrix of the uplink reference signal sent at the kth subcarrier from the pth antenna of the terminal to the rth antenna of the base station; I is the uplink interference received by the base station; and N is white noise.

[0133] Therefore, according to formula one, the corresponding relationship between the channel matrix of the uplink reference signal received by the base station and the channel data of the uplink reference signal sent by the scheduled user received by the base station and the channel data of the uplink reference signal sent by the terminal can determine the channel matrix of the uplink reference signal receiving time t (the second time), which is represented as: H t (k, r, p). Based on this principle, the channel matrix of the received uplink reference signal in a plurality of historical times or historical times can be obtained.

[0134] In the embodiment of the application, according to the above, the historical channel data includes the first channel data of the uplink reference signal sent by the terminal at the kth subcarrier and the pth antenna, and the second channel data of the uplink reference signal received by the base station at the kth subcarrier on the rth antenna of the terminal;

[0135] The channel matrix represents the channel matrix of the uplink reference signal sent at the kth subcarrier from the pth antenna of the terminal to the rth antenna of the base station at the plurality of historical times; k, p and r are integers greater than 0.

[0136] wherein each channel matrix of the uplink reference signal received at the historical time can be formed into a matrix of KxMxP dimensions, K is the number of subcarriers in the operating frequency domain of the scheduled terminal, M is the number of antennas of the base station, and P is the number of antennas of the terminal.

[0137] In the information prediction method, when the first network device obtains the channel matrix prediction value of the terminal scheduled at the first time, the first network device converts the channel matrices of the uplink reference signal received at the plurality of historical times after the first node (base station) obtains the channel matrices of the uplink reference signal received at the plurality of historical times, to obtain channel feature data of the uplink reference signal received at the plurality of historical times.

[0138] Specifically, the following Formula Two can be used to convert the channel matrix of the uplink reference signal received at the second time t to obtain the channel feature data of the uplink reference signal received at the second time t:

[0139] Formula Two:

[0140] wherein H t (k, r, p) is the channel matrix of the uplink reference signal received at the second time t; The converted channel feature data of the uplink reference signal received at the second time t; G is a structure transformation matrix.

[0141] Optionally, the channel matrix of the uplink reference signal received at the second time t can be converted by using a multi-dimensional DFT, SVD, or other structure transformation method; therefore, the structure transformation matrix G can be a DFT matrix in the multi-dimensional DFT transformation, or a transformation orthogonal basis in the SVD transformation.

[0142] According to the principle, by converting the channel matrix of the uplink reference signal received at each historical time (such as t1, t2,..., tT) in the plurality of historical times, the channel feature data of the uplink reference signal received at each historical time is obtained, that is, the time-domain predictable channel feature is obtained, which can be recorded as:

[0143] Further, according to the channel feature data of the uplink reference signal received at the plurality of historical times, the channel feature prediction value of the terminal scheduled at the first time can be obtained.

[0144] Optionally, an AR autoregressive model can be applied to time series prediction, and according to the channel feature data of the uplink reference signal received at the plurality of historical time periods, the channel feature prediction value of the terminal scheduled at the first time can be obtained.

[0145] Specifically, the following Formula Three can be used to obtain the channel feature prediction value of the terminal scheduled at the first time S

[0146] Formula Three:

[0147] wherein H S-i (k, r, p) is the channel feature data of one of the TTI time before the first time S;

[0148] m is the order of the AR model, indicating that the channel feature at the time S is related to the channel features in the m historical times; is the autoregressive coefficient of the channel feature, u S is a random disturbance term.

[0149] In this embodiment, the coefficients of the AR model can be obtained by training multiple time series to predict the time sample of the next distance of 1 TTI, and the time-domain sliding prediction distance of k TTI time sample is used, so that based on this principle, the channel feature data of the uplink reference signal received at multiple historical times can be used to obtain the channel feature prediction value of the terminal scheduled at the first time S after the multiple historical times.

[0150] Further, after obtaining the channel feature prediction value of the terminal scheduled at the first time S according to the channel feature data of the uplink reference signal received at the multiple historical times, the channel feature prediction value is inverse transformed to obtain the channel matrix prediction value of the terminal scheduled at the first time S.

[0151] Specifically, the following Formula Four can be used to inverse transform the channel feature prediction value to obtain the channel matrix prediction value of the terminal scheduled at the first time S

[0152] Formula Four:

[0153] wherein G H is a structural transformation matrix.

[0154] Based on the traditional adaptive modulation and coding (AMC) algorithm, when the base station needs to initiate uplink data service scheduling control information (DCI) to the terminal, the base station applies the last measured uplink reference signal to calculate the channel quality, which is outdated for the future uplink data service transmission time, and cannot select the appropriate MCS. By using the information prediction method described in the embodiment of the application, the first network device will send the uplink interference prediction value and / or channel matrix prediction value obtained at the first time to schedule the terminal to the first node (base station), and the base station can determine the uplink channel quality at the first time according to the uplink interference prediction value and / or channel matrix prediction value, so as to calculate the MCS value, and ensure that the selected MCS value can meet the channel quality at the uplink PUSCH data service transmission time.

[0155] In one embodiment, the first node (base station) determines the uplink channel quality at the first time according to the service transmission prediction information, including:

[0156] According to the uplink interference prediction value for scheduling the terminal at the first time, and the signal strength of the received uplink reference signal at the second time, the uplink channel quality at the first time is determined.

[0157] Specifically, the base station converts the RB / RBG-level uplink interference prediction value at the first time into the average uplink interference prediction value or the maximum uplink interference prediction value in each RB / RBG in one frequency domain for the scheduled terminal by taking the average value in the unit of RB / RBG, which is used for the base station to calculate the uplink channel quality.

[0158] Taking the uplink channel quality as an example, the base station receives the uplink reference signal at the time domain position of (n-μ) tti, needs to send the uplink data service scheduling control information DCI to the terminal at the time domain position of (n+Δ) tti, the first time is (n+Δ) tti, the second time is (n-μ) tti, and the base station calculates the uplink channel quality. The base station measures the uplink reference signal Y(n-μ) at the second time, obtains the RB / RBG-level useful signal strength S(n-μ) and the signal-to-noise ratio UL_SINR(n-μ) through channel estimation and baseband processing, and uses the uplink interference prediction value for scheduling the terminal at the first time (n+Δ) tti, and the signal strength of the received uplink reference signal at the second time (n-μ) tti, to determine the uplink channel quality UL_SINR(n+Δ) at the first time (n+Δ) tti by using the following formula five:

[0159] Formula five:

[0160] wherein, is a Gaussian white noise, RIP(n+Δ) is the uplink interference prediction value of the RB / RBG level at the first time (n+Δ) tti, and n, μ, Δ are integers greater than or equal to 1.

[0161] In this embodiment, in the scenario where the terminal is stationary or moves slowly, the reference signal strength S(n-μ) received by the base station changes little, and the first time uplink channel quality can be determined by using the above formula five.

[0162] In another embodiment, in the scenario where the terminal moves quickly or the channel changes quickly, the first node (base station) determines the uplink channel quality at the first time according to the service transmission prediction information, including:

[0164] determining the uplink channel quality at the first time according to the predicted signal strength and the uplink interference prediction value.

[0165] Specifically, the channel matrix prediction value of the terminal scheduled by the base station at the first time (n+Δ) tti can be calculated according to the calculation process of the above formula one to formula four. And further, the predicted signal strength S(n+Δ) of the uplink reference signal sent by the terminal at each subcarrier at the first time (n+Δ) tti can be calculated by the base station using the following formula six n+Δ (k,r);

[0166] Formula six:

[0167] Formula seven:

[0168] wherein, X n+Δ (k,p) is the uplink reference signal sent by the terminal at the (n+Δ) tti at the kth subcarrier and the pth antenna, wherein, according to the configuration of the base station to the terminal and the uplink power control function, X n+Δ (k,p) is the known information of the base station. K is the total number of frequency domain subcarriers of the terminal i scheduled, R is the number of receiving antennas of the base station, P is the total number of antennas of the terminal, and N_sc is the number of subcarriers contained in each RB / RBG.

[0169] Further, according to formula seven, the average useful signal strength S(n+Δ) of each RB / RBG of a certain frequency domain segment of the scheduled terminal at (n+Δ) tti can be calculated, which is used to calculate the uplink channel quality at (n+Δ) tti, such as UL_SINR(n+Δ).

[0170] Specifically, the uplink channel quality UL_SINR(n+Δ) at the (n+Δ)th tti can be calculated by the following Equation Eight:

[0171] Equation Eight:

[0172] It should be noted that the above method of determining the uplink channel quality at the first time according to the service transmission prediction information is only for illustration, and the specific implementation is not limited thereto, and each embodiment is not illustrated separately here.

[0175] Specifically, the uplink channel quality calculated by accumulating the multiple CRC check results is calibrated by the uplink channel quality calculated by the outer loop control, so as to achieve the purpose of timely and accurately reflecting the real channel quality.

[0176] In the case of positive CRC check result, the uplink channel quality at the first time calculated by the above method can be increased by a first preset value; in the case of negative CRC check result, the uplink channel quality at the first time calculated by the above method can be decreased by a second preset value, so that the accurate uplink channel quality at the first time is determined by combining the uplink channel quality at the first time calculated by the above method with the CRC check result.

[0177] In addition, in the embodiment of the application, the first node determines the modulation and coding strategy (MCS) value of the physical downlink control channel (PDCCH) sent to the terminal at the third time according to the uplink channel quality at the first time, comprising:
