[0002] In communication scenarios based on Artificial Intelligence Machine Learning (AIML), the model's input is obtained from channel estimation measurements, which can include time, phase, and power information. The reporting of channel estimation measurements is involved in both the training data collection and model inference phases.

The relevant definition of RSTD information can refer to the provisions in the existing protocol.

[0162] Furthermore, as an optional implementation, the method also includes at least one of the following:

[0183] It should be noted that when the first dataset and / or the second dataset includes information about the reference transmitting device, the third communication device adjusts the position of the channel measurement quantity corresponding to the reference transmitting device and / or the position of the first tag corresponding to the reference transmitting device in the first dataset and / or the second dataset based on the information about the reference transmitting device and the preset rules. Therefore, when the first dataset and / or the second dataset does not include information about the reference transmitting device, before executing the steps of this optional implementation, the first communication device also needs to send the information about the reference transmitting device to the third communication device. The information about the reference transmitting device can indicate the position of the channel measurement quantity and / or the first tag corresponding to the reference transmitting device in the first dataset and / or the second dataset.

[0184] It should be noted here that the channel measurements corresponding to the reference transmitting device and / or the position of the first tag in the dataset (first dataset and / or second dataset) are not considered in the data collection phase and the inference phase. Figure 9In the case shown below, that is, when the first communication device does not adjust the channel measurement quantity corresponding to the reference transmitting device and / or the position of the first tag corresponding to the reference transmitting device in the first dataset and / or the second dataset, in order to ensure the consistency of the reference transmitting device in the two stages, the following steps can be performed:

[0185] 1. The LMF entity (corresponding to the aforementioned third communication device) collects training data from different UEs (corresponding to the aforementioned first communication device). The dimensions of the training data are consistent, but the channel measurement and first tag position corresponding to the reference TRP (corresponding to the aforementioned reference transmitting device) are not fixed.

The function of this model is to output RSTD labels relative to the reference TRP (corresponding to the aforementioned target time difference information / first time difference information) based on information such as CIR / PDP in the training data.

[0187] 3. When performing inference on the UE side, the order of reference TRPs is not considered, and N CIRs / PDPs are directly input into the AI ​​model;

[0188] 4. The AI ​​model outputs RSTD labels;

[0189] 5. The UE reports the RSTD tag and the corresponding reference TRP information (corresponding to the information of the aforementioned reference transmitting device).

[0190] Furthermore, as an optional implementation, the method also includes:

[0191] According to preset rules, the positions of the channel measurement quantity corresponding to the reference transmitting device and / or the first tag corresponding to the reference transmitting device in the first dataset and / or the second dataset are adjusted; specifically, the preset rule is to place the channel measurement quantity corresponding to the reference transmitting device and / or the first tag corresponding to the reference transmitting device in the nth position in the first dataset and / or the second dataset, where n∈{1…N}, N is the total amount of data in the first dataset and / or the second dataset, and the value of n can be based on pre-configuration / pre-definition;

[0192] The adjusted first dataset and / or second dataset are sent to a third communication device; wherein the third communication device includes, for example, one or more of an LMF entity, an OAM entity, a UE vendor entity, and other third-party devices.

[0193] Below, taking the first communication device as the UE and the third communication device as the LMF entity as an example, combined with... Figure 10 Examples related to the above optional implementation methods are explained, wherein, Figure 10 R-TRP in this context stands for reference-TRP (corresponding to the aforementioned reference transmitting device):

[0194] In this example, the data collection phase and the (model) inference phase consider the location of the channel measurements and / or the first tag corresponding to the reference transmitting device in the dataset (first dataset and / or second dataset). In this way, the location of the reference TRP is consistent in both the data collection and model inference phases and can be pre-configured, for example, the nth location is the reference TRP, such as... Figure 10 As shown, the first position is the Reference TRP; specifically, to ensure that the reference TRP positions for data collection are consistent, the following methods can be used:

[0195] (1) The reference TRP sorting is completed by the UE and then uploaded to the data collection entity (third communication device);

[0196] (2) Reference TRP sorting is performed by the data collection entity (third communication device);

[0197] In Method 2, during the inference phase, the UE needs to place the reference TRP in a specified / specific location, perform inference, and then report the RSTD to the LMF. If the LMF knows the pre-configuration information of the reference TRP, the UE does not need to report the reference TRP information to the LMF.

In the first bitmap, the bits corresponding to the delays that need to be reported are 1, and the bits corresponding to the delays that do not need to be reported are 0. The length of the first bitmap is N.

[0200] The first bitmap and time slot offset; this case applies to the situation where the reference time is the boundary of the subframe where the first communication device receives the reference signal;

The specific conditions / preset conditions / predefined conditions / first conditions can include at least one of the following: the path with power greater than the set threshold a, the first N' paths with larger power, and N' less than the set threshold b.

[0203] by Figure 11 For example, when reporting channel estimation time information in bitmap format, assuming the required reporting length is N, then compared with... Figure 11 The corresponding bitmap is: 01100100100000…; when the time information of channel estimation includes the delay position, it is consistent with… Figure 11 The corresponding delay position that needs to be reported can be represented as: 000000001 / 000000010 / 00000101 / 00001000.
