The information about the reference transmitting device may indicate the position of the channel measurement amount and / or the first tag corresponding to the reference transmitting device in the first data set and / or the second data set.

[0186] Here, it should be noted that, when the channel measurement amount corresponding to the reference transmitting device and / or the position of the first tag in the data set (the first data set and / or the second data set) are not considered in the data collection phase and the inference phase (as shown in FIG9 ), that is, when the first communications device does not adjust the channel measurement amount corresponding to the reference transmitting device and / or the position of the first tag corresponding to the reference transmitting device in the first data set and / or the second data set, in order to ensure the consistency of the reference transmitting device in the two phases, the following steps can be performed:

[0187] 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 value and the first tag position corresponding to the reference TRP (corresponding to the aforementioned reference transmitting device) are not fixed;

[0188] 2. Use the collected training data to train an AI model (corresponding to the aforementioned target model). The function of this model is to output the RSTD label relative to the reference TRP (corresponding to the aforementioned target time difference information / first time difference information) based on the CIR / PDP and other information in the training data.

[0189] 3. When the UE performs inference, the order of the reference TRP is not considered and N CIRs / PDPs are directly input into the AI ​​model;

[0190] 4. The AI ​​model outputs the RSTD label;

[0191] 5. The UE reports the RSTD tag and the corresponding reference TRP information (corresponding to the information of the aforementioned reference sending device).

[0192] Furthermore, as an optional implementation, the method further includes:

[0193] Adjusting, according to a preset rule, the channel measurement amount corresponding to the reference transmitting device and / or the position of the first tag corresponding to the reference transmitting device in the first data set and / or the second data set; specifically, the preset rule is placing the channel measurement amount corresponding to the reference transmitting device and / or the first tag corresponding to the reference transmitting device at the nth position in the first data set and / or the second data set, where n∈{1…N}, N is the total amount of data in the first data set and / or the second data set, and the value of n may be based on a preconfiguration / predefinition;

[0194] Send the adjusted first data set and / or second data set to a third communication device; wherein the third communication device, for example, includes one or more of an LMF entity, an OAM entity, a UE vendor (Vendor) entity, and other third-party devices.

[0195] Below, taking the first communication device as a UE and the third communication device as an LMF entity as an example, an example related to the above optional implementation method is described in conjunction with Figure 10, wherein the R-TRP in Figure 10 is a reference-TRP (corresponding to the aforementioned reference sending device):

[0196] In this example, the channel measurement corresponding to the reference transmitting device and / or the position of the first tag in the data set (the first data set and / or the second data set) are considered in the data collection phase and the (model) inference phase. In this way, the position of the reference TRP is consistent in the data collection and model inference phases and can be pre-configured in advance. For example, the nth position is the reference TRP. As shown in FIG10 , the first position is the reference TRP. Specifically, in order to ensure the consistency of the reference TRP position in data collection, the following methods are used:

[0197] (1) The reference TRP sorting is completed by the UE and then uploaded to the data collection entity (third communication device);

[0198] (2) Reference TRP sorting is done by the data collection entity (third communication device);

[0199] Among them, in method 2, in the reasoning stage, the UE needs to place the reference TRP in a specified / specific position, perform reasoning, and then report the RSTD to the LMF. If the LMF knows the pre-configured information of the reference TRP, the UE does not need to report the reference TRP information to the LMF.

[0200] As an optional implementation, the target parameter includes time information of the channel estimation. Here, the time information of the channel estimation may be based on a sampling point or a non-sampling point. The time information of the channel estimation includes a delay position, or the time information of the channel estimation is represented by at least one of the following:

[0201] First bitmap; that is, the time information of the channel estimation is transmitted in the form of a bitmap, wherein, 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, wherein the length of the first bitmap is N;

[0202] The first bitmap and time slot offset; this case is for the case where the reference time is the subframe boundary where the first communication device receives the reference signal;

[0203] Additional path additional path.

[0204] Here, it should be noted that the case where the time information of the channel estimation includes the delay position is for the case where the first communication device needs to directly report N' delay values ​​that meet the specific condition / preset condition / predefined condition / first condition, where N' can be preconfigured or predefined. Here, the specific condition / preset condition / predefined condition / first condition can include at least one of a path with power greater than a set threshold a, the first N' paths with larger power, and N' less than a set threshold b;

[0205] Taking Figure 11 as an example, when reporting the time information of the channel estimation in the form of a bitmap, assuming that the required reporting length is N, the bitmap corresponding to Figure 11 is: 01100100100000....; when the time information of the channel estimation includes the delay position, the delay position that needs to be reported corresponding to Figure 11 can be expressed as: 000000001 / 000000010 / 00000101 / 00001000.

[0206] As an optional implementation, when the channel measurement amount includes power information of the channel estimate H, the information is reported / transmitted in at least one of the following ways:

[0207] The uplink sounding reference signal reference signal received power (UL-SRS RSRP) or the uplink sounding reference signal reference signal received path power (UL-SRS RSRPP) in the relevant protocol;

[0208] Sidelink Sounding Reference Signal Received Power (DL-SRS RSRP) or Sidelink Sounding Reference Signal Received Path Power (DL-SRS RSRPP) in the relevant protocols;

[0209] The downlink sounding reference signal reference signal received power (DL-SRS RSRP) or the downlink sounding reference signal reference signal received path power (DL-SRS RSRPP) in the relevant protocol is used.
