[0095] The wide application of 5G technology brings great changes to all aspects of people's life. According to the vision of the International Telecommunication Union (ITU), 5G will penetrate into all fields of future society to build a comprehensive information ecosystem centered on users. Among them, the 5G user experience rate can reach 100 megabits per second (Mbit / s) to 1 gigabit (Gbit / s), which can support mobile virtual reality and other extreme business experience; the 5G peak rate can reach 10 Gbit / s to 20 Gbit / s, and the traffic density can reach 10 megabits per second per square meter (Mbit / s / m2), which can support the growth of mobile business traffic by thousands of times in the future; the 5G connection number density can reach 1 million per square meter ( / m2), which can effectively support a large number of Internet of Things devices; the 5G transmission delay can reach milliseconds, which can meet the strict requirements of vehicle networking and industrial control; 5G can support a mobile speed of 500 kilometers per hour (km / h), which can meet good user experience in high-speed rail environment. It can be imagined that 5G as a new type of infrastructure representative will rebuild the future information society.

[0096] In recent years, artificial intelligence (AI) technology has made continuous breakthroughs in many fields. The continuous development of intelligent voice, computer vision and other fields not only brings a variety of applications to intelligent terminals, but also has wide application in education, transportation, home, medical care, retail, security and other fields, bringing convenience to people's life and promoting the industrial upgrading of various industries. AI technology is also accelerating the cross-penetration with other disciplines, and its development integrates knowledge from different disciplines, while also providing new directions and methods for the development of different disciplines.

[0097] In related research, RAN1 has established a research project on the introduction of artificial intelligence technology in the wireless air interface. This project studies how to introduce artificial intelligence technology in the wireless air interface, and explores how artificial intelligence technology can assist in improving the transmission technology of the wireless air interface.

[0098] In the research of 6G, the 6G system can provide more dimensional AI services. Mainly including the following aspects: AI-enabled connectivity, computing power services and extreme AI services.

[0099] Among them, AI-enabled connectivity means using AI methods to improve communication performance, such as using AI for beam management. Computing power services means that the network side can provide computing power to the terminal side, such as helping the terminal with model training, model inference, etc. Extreme AI services means enhancing the transmission pipeline of the network to improve the experience of AI application services.

[0100] For AI-based positioning, the basic principle is to train an AI model, the input of the model is based on the measurement results of the positioning reference signal, and the output of the model is the AI positioning coordinates or the intermediate parameters for AI positioning. The measurement results related to the input of the AI model, and the possible choice is based on sample-based measurement. In the standard discussion of 3GPP, the definition of sample is as follows:

[0101] The measurement consists of Nt' samples of the estimated channel response in time domain. The timing information of Nt' samples is reported with a timing granularity T, where T = 2 k × Tc. Where k represents the time reporting granularity factor, and Tc is the basic time unit of NR. Where the corresponding measurement value (such as the reported power) corresponds to the measurement value of the reported Nt' samples.

[0102] Nt' and k can be signalled. Further study (FFS): the value range of Nt'; the value range of the timing granularity T is an integer.

[0103] The timing information is defined with respect to a reference time.

[0104] The determination of Nt' and k (including signaling) needs to be further discussed, and the rule of selecting Nt' samples is introduced. For sample-based measurement, for example, for TRP / gNB measurement, Nt' selected samples should have the highest power.

[0105] In general, sample-based measurement results, for time-domain sampling signals, the interval of the sampling signal can be 2 k × Tc, and in a time window, Nt' sampling points are selected according to the rule. However, in the current discussion, there is no corresponding mechanism to effectively determine this time window.

[0107] FIG. 2A is an interaction diagram of a communication method, according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a communication method, and the method comprises:

[0108] In step S2101, the second device sends first information to the first device.

[0109] In some embodiments, the first device receives the first information sent by the second device.

[0110] In some embodiments, the first device can be a terminal, or an access network device (e.g., a base station), but is not limited thereto.

[0111] In some embodiments, the second device can be a core network device, for example, a location management function (LMF), but is not limited thereto.

[0112] In some embodiments, the first information indicates a first time window start point.

[0113] The first time window start point refers to a starting time point (also referred to as a starting time) of the first time window.

[0114] In some embodiments, the first information is used to configure the first time window start point.

[0115] In some embodiments, the first time window start point is represented based on a sequence number of a time sampling point.

[0116] For example, the first time window start point is represented by an Mth time sampling point, where M is a positive integer.

[0117] For example, a plurality of time sampling points are numbered in advance, and the first information indicates that an Mth time sampling point in the plurality of time sampling points is the first time window start point.

[0118] In some embodiments, the second device can determine the first time window start point.

[0119] In some embodiments, the first time window start point is determined based on at least one of: a time start point of sending a positioning reference signal; a time start point of receiving a positioning reference signal; a first absolute reference time.

[0120] The time start point of sending a positioning reference signal refers to a time at which a sending device starts to send a positioning reference signal, and the time start point of receiving a positioning reference signal refers to a time at which a receiving device starts to receive a positioning reference signal. In an example, the sending device can be a terminal, and the receiving device can be an access network device. In another example, the sending device can be an access network device, and the receiving device can be a base station.

[0121] The first absolute reference time can be any one absolute reference time, for example, 1900 AD 0:00:00.

[0122] For example, the second device takes the time point at which the positioning reference signal is sent as the start of the first time window, or the second device takes the time point at which the positioning reference signal is received as the start of the first time window, or the second device takes the first absolute reference time as the start of the first time window.

[0123] In some embodiments, the first information indicates the start of the first time window corresponding to different first devices respectively.

[0124] For example, the LMF indicates different first time window starts for different terminals or base stations.

[0125] Step S2102: The second device sends second information to the first device.

[0126] In some embodiments, the first device receives the second information sent by the second device.

[0127] In some embodiments, the second information indicates the number of first time sampling points.

[0128] The first time sampling point refers to all time sampling points included in the first time window.

[0129] In some embodiments, the number of first time sampling points included in the first time window is determined based on at least one of the following: protocol predefinition; first device capability, the first device capability including the number of time sampling points supported by the first device.

[0130] In some embodiments, the second device can determine the number of first time sampling points.

[0131] For example, the second device can determine the number of first time sampling points based on the first device capability, wherein the number of first time sampling points is less than or equal to the number of time sampling points supported by the first device.

[0132] In some embodiments, the second information indicates the number of first time sampling points corresponding to different first devices respectively.

[0133] For example, the LMF indicates different numbers of first time sampling points for different terminals or base stations.

[0134] Step S2103: The first device determines the first time window.

[0135] The first time window includes the start of the first time window and a plurality of first time sampling points.

[0136] In some embodiments, the first device determines the first time window start point and / or the number of the first time sampling points included in the first time window.

[0137] The first time window start point can be denoted by T0, and the number of the first time sampling points can be denoted by N.

[0138] FIG. 2B is a schematic diagram illustrating a first time window according to an example. As shown in FIG. 2B, the first time window includes a first time window start point T0, and a plurality of first time sampling points included in the first time window.

[0139] In some embodiments, the first device can determine the first time window start point by itself, or determine the first time window start point based on the first information sent by the second device.

[0140] In some embodiments, the first time window start point is determined based on at least one of: a time start point of sending the positioning reference signal; a time start point of receiving the positioning reference signal; a first absolute reference time.

[0141] For example, the first device takes the time start point of sending the positioning reference signal as the first time window start point, or the first device takes the time start point of receiving the positioning reference signal as the first time window start point, or the first device takes the first absolute reference time as the first time window start point.

[0142] In some embodiments, the first device can determine the number of the first time sampling points by itself, or determine the number of the first time sampling points based on the second information sent by the second device.

[0143] In some embodiments, the first device determines the number of the first time sampling points, and sends the number of the first time sampling points to the second device.

[0144] In some embodiments, the second device receives the number of the first time sampling points sent by the first device.

[0145] In some embodiments, the first device can determine the first time window based on the first time window start point and the number of the first time sampling points.

[0146] In step S2104, the first device determines a plurality of second time sampling points from the plurality of first time sampling points.

[0147] In some embodiments, the second time sampling point refers to a time sampling point determined from the first time sampling points for measurement. The number of the second time sampling points can be denoted by N', and the number of the second time sampling points is less than or equal to the number of the first time sampling points.

[0148] In some embodiments, the number of the second time sampling points is determined based on at least one of the following: protocol predefinition; network device configuration; first device determination.

[0149] For example, the protocol can predefine the number of the second time sampling points.

[0150] For example, the network device can configure the number of the second time sampling points and indicate the number of the second time sampling points to the first device.

[0151] For example, the first device can determine the number of the second time sampling points by itself.

[0152] At step S2105, the first device obtains measurement results based on the plurality of second time sampling points.

[0153] In some embodiments, the first device can perform measurement at each of the second time sampling points to obtain the measurement results.

[0154] In some embodiments, the measurement results are used for artificial intelligence (AI) positioning. That is, the measurement results are used to directly or indirectly determine positioning coordinates.

[0155] In some embodiments, the measurement results obtained by performing measurement at the plurality of second time sampling points can be input into an AI positioning model to obtain positioning coordinates or intermediate parameters used for positioning.

[0156] In some embodiments, the first device can report the measurement results to the second device.

[0157] At step S2106, the first device determines a second time window start point.

[0158] In some embodiments, the second time window start point refers to a recommended time window start point determined by the first device, and the second time window start point and the first time window start point can be the same or different.

[0159] In some embodiments, the terminal or the base station determines the time window start point by itself and reports the recommended time window start point to the LMF.

[0160] At step S2107, the first device sends the second time window start point to the second device.

[0161] In some embodiments, the second time window start point is used to redetermine the first time window start point.

[0162] In some embodiments, the second device receives the second time window start point sent by the first device, and redetermines the first time window start point based on the second time window start point sent by the first device.

[0163] For example, the first device determines the first time window based on the first time window start point and the number of the first sampling time points, determines the plurality of second sampling time points from the plurality of first sampling time points included in the first time window, performs measurement based on the plurality of second sampling time points to obtain a measurement result, and reports the measurement result. When the first device observes that the plurality of second sampling time points are always concentrated in a certain time region, the first device can report a suggested second time window start point to the second device, and the second device can determine the first time window start point based on the second time window start point. The second device can indicate the determined first time window start point to the first device, and the first device determines the first time window based on the determined first time window start point.

[0249] In some embodiments, the LMF sends second information to the terminal or to the base station, the second information being used to configure the number of sampling points contained in the first time window.

[0250] In some embodiments, the number of sampling points contained in the first time window indicated by the second information is different for different terminals or different base stations.

[0253] In some embodiments, the N' can also be determined according to one of the following methods: predefinition; network configuration; terminal or base station self-determination and indication.
