[0037] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present disclosure.

[0038] It should be understood that in the embodiments of the present disclosure, devices with communication functions in a network / system may be referred to as communication devices. Taking the communication system 100 shown in Figure 1 as an example, the communication devices may include a network device 110 and a terminal 120 with communication functions. Network device 110 and terminal 120 may be the specific devices described above and will not be described in detail here.

[0039] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0040] To facilitate understanding of the technical solutions of the embodiments of the present disclosure, the technical solutions related to the embodiments of the present disclosure are described below.

[0041] Existing research results show that artificial intelligence (AI) can already obtain corresponding gains in multiple fields such as CSI feedback, beam management, and positioning under the existing 5G design framework, showing considerable application prospects. A typical use case for beam management is time domain beam prediction / tracking under high-speed movement. As shown in Figure 2, Figure 2 is a beam prediction schematic diagram provided by an embodiment of the present disclosure. For traditional solutions, for example, the beam tracking frequency is set to once every 40ms, and each time the partial beam quality is measured and reported according to CSI-ReportConfig. For AI-based time domain beam prediction on the terminal side, for example, the time interval between adjacent sampling points of beam tracking is 40ms, based on the measured partial beam quality of 4 consecutive sampling points, the quality of the best beam in the partial beam at the next 4 moments is predicted and reported, or the quality of the best beam in all beams at the next 4 moments is predicted and reported, and then the UE sends the beam report according to a specific sending method.

[0042] The AI-based time-domain beam prediction method first trains on a large dataset, such as one containing millions of samples, each containing the Reference Signal Received Power (RSRP) of all beam pairs at multiple time instants. During training, the RSRP values ​​of a small number of beam pairs at several time instants are used as input to an AI model (typically a neural network), and the RSRP values ​​of all beam pairs at several time instants are used as labels for the AI ​​model's output. The AI ​​model's parameters are continuously updated using a gradient descent algorithm until the error between the AI ​​model output and the label (measured by the Normalized Mean Square Error (NMSE)) is less than a threshold. This indicates that the model has converged and has good prediction capabilities. In actual use, the RSRP values ​​measured at several time instants are used as input to the AI ​​model, which outputs predicted RSRP values ​​for all beam pairs at several future time instants. Based on the predicted RSRP values ​​of the K optimal beam pairs at each future time instant and the beam pair load, the base station determines the beam pair to use for terminal data transmission and issues beam instructions.

[0043] When the terminal speed changes, to ensure the AI ​​model's prediction accuracy, it is necessary to measure the time window length and measurement interval of the CSI-RS reference signal, and to change the reporting period. For example, at a speed of 30 km / h, four historical RSRP measurement results at 80 ms intervals can be used to predict the RSRP for the next four moments. At a speed of 90 km / h, eight historical RSRP measurement results at 80 ms intervals can be used to predict the RSRP for the next four moments to obtain a more accurate result. At 90 km / h, four historical RSRP measurement results at 40 ms intervals can be used to predict the RSRP for the next four moments to obtain a more accurate result.

[0044] The existing CSI reporting framework can only be configured with one periodic CSI-RS resource set. The same CSI reporting configuration cannot adapt to the CSI resource measurement and reporting requirements of the terminal at different speeds. If multiple CSI reporting configurations are used to correspond to different terminal speeds, it will result in high signaling overhead.

[0131] Table 6

[0132] Among them, uetimeprediction represents terminal-side reasoning, the starting time of the prediction is the reference time point (such as the reporting time) plus the time offset slotoffset (corresponding to the first information), and the prediction time interval is intervalofPrediction (corresponding to the second information). Starting from the starting time of the prediction, the terminal predicts and reports the beam quality at the moment indicated by the bitmap ReportBeam (corresponding to the fourth information) in the future nrofBeamPrediction (corresponding to the fifth information) prediction moments. AIreportConfigType indicates the reporting period and reporting resources adapted to different speeds, periodic is used to indicate periodic reporting, and reportSlotConfig (corresponding to the sixth information) is used to indicate the reporting period and reporting period offset at different speeds. pucch-CSI-ResourceList (corresponding to the seventh information) is used to indicate the PUCCH resources used for CSI reporting at different speeds.

The starting position of the prediction window is the reference time point (for example, the reporting time) plus the time offset slotoffset. The prediction window length is Prewinlength. The prediction time interval Preinterval within the prediction window is equal to the measurement time interval. The network device predicts the beam quality at the moment indicated by the bitmap ReportBeam within the window. AIreportConfigType indicates the reporting period and reporting resources adapted to different speeds. When the terminal speed changes, the current speed is reported so that the base station can confirm the resources used for CSI reporting.

Meainterval indicates that the measurement window lengths are 40ms, 40ms, 40ms, and 40ms when the terminal speeds are 30km / h, 60km / h, 90km / h, and 120km / h, respectively. Meawinslidelength indicates that the measurement window sliding lengths are 160ms, 160ms, 80ms, and 80ms when the terminal speeds are 30km / h, 60km / h, 90km / h, and 120km / h, respectively.

[0140] Table 8 below provides the reporting configuration information:

[0141] Table 8

[0142] Uetimeprediction instructs the terminal side to make predictions, slotoffset indicates that the time offset is 0, Prewinlength indicates that when the terminal speed is 30km / h, 60km / h, 90km / h and 120km / h, the prediction window length is 160ms, 160ms, 80ms and 80ms respectively; ReportBeam indicates that when the terminal speed is 30km / h, 60km / h, 90km / h and 120km / h, the time to be predicted is 1111, 1111, 11, 11 respectively; reportSlotConfig indicates that when the terminal speed is 30km / h, the CSI reporting period and reporting period offset are 160ms and 140ms respectively, and when the terminal speed is 60km / h, the CSI reporting period and reporting period offset are 160ms and 140ms respectively. The period offsets are 160ms and 140ms respectively. The terminal speed is 90km / h, the CSI reporting period and reporting period offset are 80ms and 60ms respectively. The terminal speed is 120km / h, and the CSI reporting period and reporting period offset are 80ms and 60ms respectively. The pucch-CSI-ResourceList indicates that the resource used when the terminal speed is 30km / h is PUCCH-CSI-Resource10, the resource used when the terminal speed is 60km / h is PUCCH-CSI-Resource10, the resource used when the terminal speed is 90km / h is PUCCH-CSI-Resource20, and the resource used when the terminal speed is 120km / h is PUCCH-CSI-Resource20.

[0143] When the terminal speed is 30 km / h, the configuration is as shown in Figure 5. The measurement window length is 160 ms, and the measurement interval is 40 ms. Therefore, all four moments within the measurement window (four periodic resource sets) need to be measured. The prediction window length is 160 ms, and the prediction interval is 40 ms. The prediction window includes four moments that need to be predicted. The CSI reporting period is 160 ms, and the reported resource is the PUCCH resource with ID = 10.

[0144] The terminal uses the RSRP results of the four configured measurements as the input of the AI ​​model, outputs the RSRP of all beam pairs for the next four moments, and reports the sequence number and RSRP of the top K (for example, K = 5) optimal beam pairs in each of the next four moments to the base station via PUCCH 10. The base station determines the beam pair used by the terminal for data transmission based on the RSRP value and the load of the beam pair, and performs beam indication. For example, if the RSRP of beam pairs 1, 1, 2, and 3 is the highest at the 1st, 2nd, 3rd, and 4th moments in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1, 1, 2, and 3 to transmit data at the 1st, 2nd, 3rd, and 4th moments in the future, respectively.

[0145] When the terminal's speed reaches 90 km / h, it reports the speed to the base station so that the base station knows the reporting resources used by the terminal. As shown in Figure 6, at a speed of 90 km / h, the measurement window length is 240 ms, and the measurement interval is 40 ms. Therefore, the measurement window contains six moments (six periods of resource sets) that need to be measured. The prediction window length is 80 ms, and the prediction interval is 40 ms. The prediction window contains two moments that need to be predicted. The CSI reporting period is 80 ms, and the reporting resource is the PUCCH resource with ID = 20.

[0146] The terminal uses the RSRP results of the configured six measured moments as the input of the AI ​​model, outputs the RSRP of all beam pairs in the next two moments, and reports the sequence number and RSRP of the top K optimal beam pairs in each of the next two moments to the base station through PUCCH 20. For example, if the RSRP of beam pairs 1 and 3 is the highest at the first and second moments in the future, and the beam pair load is not overloaded, the base station instructs the terminal to use beam pairs 1 and 3 to transmit data at the first and second moments in the future, respectively.

[0147] Example 2

[0148] Referring to Figures 7 and 8, Figure 7 is a fourth schematic diagram of beam prediction provided in an embodiment of the present disclosure, and Figure 8 is a fifth schematic diagram of beam prediction provided in an embodiment of the present disclosure. The base station has a total of 32 transmit beams and the terminal has 4 receive beams. The resource set configured with CSI-ReportConfig contains 8*4 reference signal / beam pairs, and the CSI resource set transmission period is 40ms (1 time slot = 1ms). During terminal-side inference, the AI-based CSI reporting configuration is as follows:

[0149] Table 9 below gives the measurement configuration information:

[0150] Table 9

[0151] Meawinlength indicates that the measurement window lengths are 240ms, 160ms, 160ms, and 160ms when the terminal speeds are 30km / h, 60km / h, 90km / h, and 120km / h, respectively. Meainterval indicates that the measurement window lengths are 120ms, 80ms, 40ms, and 40ms when the terminal speeds are 30km / h, 60km / h, 90km / h, and 120km / h, respectively. Meawinslidelength indicates that the measurement window sliding lengths are 240ms, 160ms, 160ms, and 160ms when the terminal speeds are 30km / h, 60km / h, 90km / h, and 120km / h, respectively.

[0152] Table 10 below shows the reporting configuration information:

[0153] Table 10

[0154] Uetimeprediction instructs the terminal side to make predictions, slotoffset indicates that the time offset is 0, Prewinlength indicates that when the terminal speed is 30km / h, 60km / h, 90km / h and 120km / h, the prediction window length is 240ms, 160ms, 160ms and 160ms respectively; ReportBeam indicates that when the terminal speed is 30km / h, 60km / h, 90km / h and 120km / h, the time to be predicted is 11, 11, 1111 and 1111 respectively; reportSlotConfig indicates that when the terminal speed is 30km / h, the CSI reporting period and reporting period offset are 240ms and 220ms respectively, and when the terminal speed is 60km / h, the CSI reporting period and reporting period offset are 240ms and 220ms respectively. The CSI reporting period and reporting period offset are 160ms and 140ms respectively, the terminal speed is 90km / h, the CSI reporting period and reporting period offset are 160ms and 140ms respectively, the terminal speed is 120km / h, the CSI reporting period and reporting period offset are 160ms and 140ms respectively; pucch-CSI-ResourceList indicates that the resource used when the terminal speed is 30km / h is PUCCH-CSI-Resource10, the resource used when the terminal speed is 60km / h is PUCCH-CSI-Resource10, the resource used when the terminal speed is 90km / h is PUCCH-CSI-Resource20, and the resource used when the terminal speed is 120km / h is PUCCH-CSI-Resource20.

[0155] When the terminal speed is 60 km / h, the configuration is as shown in Figure 7. The measurement window length is 160 ms, and the measurement interval is 80 ms. Therefore, of the four moments (four resource sets) included in the measurement window, two moments (two resource sets) need to be measured. The prediction window length is 160 ms, and the prediction interval is 80 ms. The prediction window includes two moments that need to be predicted. The CSI reporting period is 160 ms, and the reported resource is the PUCCH resource with ID = 10.

[0156] When the terminal's speed changes to 90 km / h, it reports the speed to the base station so that the base station knows the reporting resources used by the terminal. As shown in Figure 8, the measurement window length is 160 ms, and the measurement interval is 40 ms. Therefore, the measurement window contains four moments (four periods of resource sets) that need to be measured. The prediction window length is 160 ms, and the prediction interval is 40 ms. The prediction window contains four moments that need to be predicted. The CSI reporting period is 160 ms, and the reporting resource is the PUCCH resource with id = 20.
