However, this is not the only possibility.

[0102] In some embodiments, the core network equipment may be a single device, multiple devices, or a group of devices. The core network may include at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), and Next Generation Core (NGC).

[0103] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0104] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are examples. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A.

[0106] In some embodiments of this disclosure, the 5G NR system introduces prediction based on Artificial Intelligence (AI) / Machine Learning (ML) models to simplify processes and improve performance in certain scenarios. One typical scenario is the uplink power control process. For example, in the traditional open-loop power control process, the UE determines the uplink transmission power according to the following formula:

[0107] P PRACH,b,f,c (i)=min{P CMAX,f,c (i),P PRACH,target,f,c +PL b,f,c [dBm] (1)

[0108] Among them, P PRACH,b,f,c (i) represents the UE's transmit power, b represents the ULBWP, f is the carrier frequency, and c is the serving cell; P CMAX,f,c (i) To configure the UE's maximum transmit power, the protocol value is defined in 38.101-1; P PRACH,target,f,c PL represents the received power of the target PRACH on the network side. b,f,c This represents the path loss value obtained by the UE based on DLRS measurements.

[0109] Path loss is the power pulsation (PL) value evaluated based on the signal strength of the downlink reference signal (SSB or CSI-RS) measured by the UE. Figure 1B is a schematic diagram of a measurement process according to an embodiment of this disclosure. As shown in Figure 1B, the UE needs to frequently measure the downlink PLRS, resulting in high power consumption. Furthermore, if the channel changes rapidly, the downlink measurement cannot accurately reflect the current PL value.

[0110] In some embodiments, to reduce downlink PLRS measurements and save power, a predicted PL value can be output based on the training and prediction of an AL / ML model. Figure 1C is a schematic diagram of a prediction process according to an embodiment of the present disclosure. As shown in Figure 1C, the UE can predict the PL value through AI, and then determine the uplink transmission power based on the predicted PL value.

[0112] Step S2101: The network device sends the second information to the terminal device.

[0113] In some embodiments, the terminal device may receive second information. For example, the terminal device may receive second information sent by a network device. As another example, the terminal device may also receive second information sent by other entities.

[0114] In some embodiments, the second information may be used to indicate the first transmission information.

[0115] In some embodiments, the first transmission information may be the power value or signal strength value of a path loss reference signal (PLRS) sent by the network device.

[0116] In some embodiments, "emission" may also be referred to as "sending".

[0117] In some embodiments, the PL RS can be a downlink reference signal, such as a synchronization signal block (SSB) and / or a channel state information reference signal (CSI-RS), which is not limited in this disclosure.

[0118] For example, the first transmission information could be the power value or signal strength value of the SSB, or, for another example, the first transmission information could be the power value or signal strength value of the CSI-RS.

[0119] In some embodiments, the first transmission information may be the power value or signal strength value of a PL RS, or it may include the power values ​​or signal strength values ​​of multiple PL RSs.

[0120] In some embodiments, if the first transmission information includes the power values ​​or signal strength values ​​of multiple PL RS, the network device may transmit the power values ​​or signal strength values ​​of the PL RS at different times according to the protocol.

[0121] In some embodiments, when a network device sends a PL RS to a terminal device, it may simultaneously send the second information to the terminal device.

[0122] In some embodiments, the network device may also send second information indicating the power value or signal strength value of the PLRS to the terminal device before or after sending the PLRS to the terminal device, and this disclosure does not limit this.

[0123] In some embodiments, the first transmission information can be used by the terminal device to predict the path loss value between the terminal device and the network device.

[0124] In some embodiments, the name of the first transmission information is not limited, and may be, for example, "first transmission power" or "first signal strength".

For example, the first transmission information is the power value or signal strength value of the PLRS transmitted by the network device at a first moment, and the first reception information is the power value or signal strength value of the PLRS transmitted by the network device at a first moment measured by the terminal device.

[0139] It should be noted that the first transmission information and the first reception information may correspond to different PL RS, and this disclosure does not limit this.

[0146] In some embodiments, the method of obtaining the first sample information can refer to the method of obtaining the first information described above, and will not be repeated here.

[0147] In some embodiments, the PL RS corresponding to the first sample information can be any PL RS obtained within a historical time period, and this disclosure does not limit this.

[0148] In some embodiments, after obtaining the first sample information, the model can be trained based on the first sample information to obtain the first model.

[0149] In some embodiments, the first model can be obtained by training the model using multiple first sample information.

[0150] In some embodiments, the multiple first sample information may be information acquired by the terminal device at different locations and / or at different times.

[0151] In some embodiments, the first sample information may be information prior to the first information time period.

[0152] For example, if the first information is information obtained at the current moment, then the first sample information can be information obtained before the current moment.

[0153] Figure 2B is a schematic diagram illustrating model training according to an embodiment of the present disclosure. As shown in Figure 2B, by inputting the second transmission information, the second reception information, the second beam index, and the second position of the terminal device into the AI / ML model, a predicted path loss value can be output.

[0154] In some embodiments, the training process of the first model can be described with reference to existing technologies, and will not be repeated here.

[0155] In some embodiments, the terminal device can input the first transmission information, the first reception information, the first beam index, and the first location into the first model to obtain the path loss value between the terminal device and the network device output by the first model.

[0156] In some embodiments, the first model can be trained using any one or more pieces of information from the first sample information.

[0157] In some embodiments, a first model trained with different information can predict path loss values ​​for different scenarios. For example, a first model trained with second transmit information, second receive information, and a second beam index can be used to predict path loss values ​​for a future time period; as another example, a first model trained with second transmit information, a second beam index, and a second location can be used to predict path loss values ​​for a specified location.

[0158] It should be noted that when predicting path loss values ​​using the first model, the parameters input to the first model are the same as the parameters used to train the first model. For example, if the first model is trained using second transmit information, second receive information, and a second beam index, then the information input when predicting path loss values ​​using the first model can include the first transmit information, the first receive information, and the first beam index.

[0159] In some embodiments, the first model can be used to predict path loss values ​​over a time period.

[0160] In some embodiments, the first model can be trained using second transmission information, second reception information, and a second beam index. The second transmission information is the power value or signal strength value of the PL RS sent by the network device, the second reception information is the power value or signal strength value of the PL RS measured by the terminal device, and the second beam index is the beam index value corresponding to the PL RS.

[0161] In some embodiments, when predicting path loss values ​​over a time period, the first information input to the first model may include at least the following parameters:

[0162] The first transmission information, the first reception information, and the first beam index.

[0163] In some embodiments, the first terminal can input the first transmission information, the first reception information, and the first beam index into the first model to obtain the path loss value of the second time period output by the first model, wherein the second time period is the time period after the first time period.

[0164] For example, the first time period is (1,…,i-1), and the second time period is (i,…,i+j). Here, i can be the current time, meaning that the first time period includes the time period before the current time, and the second time period can include the current time and the time period after the current time.

[0165] Figure 2C is a schematic diagram illustrating a prediction process according to an embodiment of the present disclosure. As shown in Figure 2C, the inputs of the first model are the first transmission information of the first time period, the first reception information of the first time period, and the first beam index of the first time period, and the output of the first model is the path loss value of the second time period.

[0166] In some embodiments, the first model can be used to predict the path loss value at a location.

[0167] In some embodiments, the first model can be trained using second transmission information, a second beam index, and a second location of the terminal device. The second transmission information is the power value or signal strength value of the PL RS sent by the network device, and the second beam index is the beam index value corresponding to the PL RS.

[0168] In some embodiments, when predicting the path loss value at a location, the first information input to the first model may include at least the following parameters:

[0169] The first transmission information, the first beam index, and the first position.

[0170] In some embodiments, the first terminal can input the first transmission information, the first beam index, and the first position into the first model to obtain the path loss value of the first position output by the first model.

[0171] In some embodiments, "path loss value at the first location" can be understood as "path loss value of the terminal device at the first location during the second time period". For example, the path loss value of the terminal device at the first location at time i can be predicted.

[0172] Figure 2D is a schematic diagram illustrating a prediction process according to an embodiment of the present disclosure. As shown in Figure 2D, the inputs of the first model are the first transmission information at time i, the first beam index, and the first position at time i, and the output of the first model is the path loss value at the first position at time i.

[0173] Step S2103: The terminal device determines the uplink transmission power based on the path loss value.

[0174] It should be noted that terminal devices can determine the uplink transmit power according to the methods defined in the existing protocols, which will not be elaborated here.

[0175] Using the above method, the terminal device does not need to measure the downlink path loss reference signal. The path loss value between the terminal device and the network device is predicted based on the first information to determine the uplink transmission power, thereby reducing the power consumption of the terminal device and saving power.
