Referring to fig. 1, a schematic structural diagram of a wireless communication system according to an embodiment of the disclosure is shown. As shown in fig. 1, the wireless communication system is a communication system based on a cellular mobile communication technology, and may include: a number of terminals 11 and a number of base stations 12.

Where the terminal 11 may be a device providing voice and/or data connectivity to a user. The terminal 11 may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), and the terminal 11 may be an internet of things terminal such as a sensor device, a mobile phone (or "cellular" phone) and a computer with an internet of things terminal, for example, a stationary, portable, pocket, hand-held, computer-built-in or vehicle-mounted device. Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile Station), mobile Station (mobile), remote Station (remote Station), access point, remote terminal (remote terminal), access terminal (access terminal), user equipment (user terminal), user agent (user agent), user device (user equipment), or user terminal (UE). Alternatively, the terminal 11 may be an unmanned aerial vehicle device. Alternatively, the terminal 11 may be a vehicle-mounted device, for example, a car-driving computer having a wireless communication function, or a wireless communication device externally connected to the car-driving computer. Alternatively, the terminal 11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices having a wireless communication function.

The base station 12 may be a network-side device in a wireless communication system. Wherein the wireless communication system may be a fourth generation mobile communication technology (the 4th generation mobile communication,4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, new Generation radio access network). Or, an MTC system.

Wherein the base station 12 may be an evolved base station (eNB) employed in a 4G system. Alternatively, the base station 12 may be a base station (gNB) in a 5G system employing a centralized and distributed architecture. When the base station 12 employs a centralized and distributed architecture, it typically includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is provided in the distribution unit, and the specific implementation of the base station 12 is not limited by the embodiment of the present disclosure.

A wireless connection may be established between the base station 12 and the terminal 11 over a wireless air interface. In various embodiments, the wireless air interface is a fourth generation mobile communication network technology (4G) standard-based wireless air interface; or, the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G-based technology standard of a next generation mobile communication network.

In some embodiments, an E2E (End to End) connection may also be established between terminals 11. Such as V2V (vehicle to vehicle, vehicle-to-vehicle) communications, V2I (vehicle to Infrastructure, vehicle-to-road side equipment) communications, and V2P (vehicle to pedestrian, vehicle-to-person) communications among internet of vehicles communications (vehicle to everything, V2X).

In some embodiments, the above wireless communication system may further comprise a network management device 13.

The plurality of base stations 12 are respectively connected to the network management device 13. The network management device 13 may be a core network device in a wireless communication system, for example, the network management device 13 may be a mobility management entity (Mobility Management Entity, MME) in an evolved packet core network (Evolved Packet Core, EPC). Alternatively, the network management device may be other core network devices, such as a Serving GateWay (SGW), a public data network GateWay (Public Data Network GateWay, PGW), a policy and charging rules function (Policy and Charging Rules Function, PCRF) or a home subscriber server (Home Subscriber Server, HSS), etc. The embodiment of the present disclosure is not limited to the implementation form of the network management device 13.

In a new air interface (NR) system, positioning may be achieved by a variety of methods, for example: NR Enhanced Cell ID (E-CID, enhanced Cell-ID positioning method), positioning NR DownLink Time difference of arrival positioning (DL-TDOA, down Link-Time Difference Of Arrival), NR UpLink Time difference of arrival (UL-TDOA, upLink-Time Difference Of Arrival) positioning, NR Multi-Cell Round Trip Time (Multi-RTT) positioning, NR DownLink past angle positioning, NR UpLink angle of arrival positioning, and the like. The above positioning method relies on UE measurements of Positioning Reference Signals (PRS), such as: the time difference of arrival is measured, the reference signal received power (RSRP, reference Signal Receiving Power) is measured or the angle of arrival or signal strength etc. is measured at the base station side depending on the UE transmitting the corresponding reference symbols.

In positioning, positioning accuracy is related to the bandwidth occupied by PRS. The wider the bandwidth occupied by the PRS, the higher the positioning accuracy in the same case, and vice versa, the lower the positioning accuracy.

In practical application, on one hand, due to the limitation of the terminal capability, for example, some RedCap UEs such as internet of things terminals, the bandwidth of the RedCap UEs is only 5M or 20MHz, and due to the limitation of the terminal capability, the positioning accuracy of the RedCap UEs is also very limited. On the other hand, if the base station adopts a large bandwidth to transmit the PRS, more network resources are occupied, meanwhile, when the terminal receives the large bandwidth PRS, the terminal needs to open a large bandwidth radio frequency receiver, and the power of the terminal can be improved.

Therefore, how to improve the positioning accuracy in the case of a UE with smaller bandwidth capability is a problem to be solved.

As shown in fig. 2, the present exemplary embodiment provides a positioning method, which can be performed by a communication device of a cellular mobile communication system, including:

step 201: determining the position information of a first UE by adopting a positioning model according to the received information of a reference signal associated with the first UE after passing through a channel; the positioning model is obtained by training according to the received information of the reference signal associated with the second UE after the reference signal passes through the channel and the position information of the second UE.

Since many different types of UEs may be included in a communication network, in all embodiments of the present disclosure, a positioning model needs to be trained separately for the different types of UEs. Among them, different types of UEs refer to different frequency bandwidths supported by the UEs (i.e., different UE bandwidth capabilities). For example, communication networks may include; eRedCAP UE supporting 5MHz, redCAP UE supporting 20MHz, and general UE. Of course, the normal UE and the RedCap UE necessarily support an operating frequency bandwidth of 5 MHz; therefore, the data of the normal UE and the RedCap UE can be used as training samples to train the location model of the erecap UE with the 5MHz operating frequency bandwidth. The operating frequency bandwidth of the second UE is greater than or equal to the first UE. In this way, the second UE can train with the receiving information and the position information under the same operating frequency bandwidth as the first UE as training samples (which may also be referred to as training data); or the second UE may train with the received information and the location information corresponding to the same reference signal configuration bandwidth as the first UE as training samples. In this way, the data of the second UE can be used as a training sample to obtain the positioning model corresponding to the first UE. The scheme of training by using the training samples to obtain the positioning model in the embodiment of the disclosure may be performed by the first UE or may be performed by the second UE or the network side device, which is not limited herein.

The reference signal configuration bandwidth refers to a bandwidth of a transmitted reference signal. For example, a reference signal with a bandwidth of 5MHz may also be used at a UE supporting 20 MHz. At this time, the received information and the position information corresponding to the bandwidth of the reference signal configuration can be used as training samples corresponding to the bandwidth of the reference signal with the bandwidth of 5MHz for training.

The method of the present example may be performed by a communication device in a communication system, such as a core network device, a base station or a UE in a cellular mobile communication system. The positioning model may be deployed within a communication device in a communication system, such as a core network device, a base station or a UE in a cellular mobile communication system. The communication device performing the method of the embodiment may be the same device or different devices from the communication device deploying the positioning model. The communication device performing the method may invoke the positioning model from the communication device deploying the positioning model.

It should be noted that, for the definition of the same parameter, the core network device side, the base station side and the UE side may be the same, so that the description is omitted.

The reference signal may be a radio reference signal dedicated to positioning, or may be another radio reference signal.

The base station transmits a reference signal to the first UE;

and the first UE transmits a reference signal to the base station.

The received information of the reference signal after passing through the channel may include: parameter variation of the reference signal after passing through the channel and/or specific transmission attribute of the reference signal in the channel transmission process, etc. Here, the parameter variation of the reference signal after passing through the channel may include: a change in signal strength, a change in frequency, etc., a change in signal angle, etc.

Here, the channel may include a physical transmission space that is a reference signal. The channel will act on the passing signal, causing a change in signal parameters, different channels acting differently. The reference signal is transmitted in the channel by being influenced by the transmission distance, the environment (e.g., obstacles, etc.) in the channel. Therefore, the UE is located in a different location, and the effect of the channel on the reference signal generation is also different. The location where the UE is located and the effect of the channel on the reference signal may have a correlation, which may be considered as a correspondence; i.e. the position where the UE is located and the parameter variation of the reference signal after the channel has passed may have a correspondence.

Specific transmission properties of the signal during channel transmission: may include the duration of the transmission of the signal, the attenuation of the transmission, etc. The UE is located in different locations, and specific transmission properties of signals after passing through the channel are different. The location where the UE is located and the specific transmission properties of the signal during channel transmission may also have a correlation, which may be considered as a kind of correspondence.

In one embodiment, the network-side device such as the base station or the UE may determine the received information of the reference signal after passing through the channel.

The received information of the reference signal after passing through the channel may be determined based on the reference signal transmitted by the base station and the reference signal received by the UE. The received information of the reference signal after passing through the channel may also be determined based on the reference signal transmitted by the UE and the reference signal received by the base station.

For example, the base station transmits the reference signal through the second parameter, the UE may transmit the first parameter of the reference signal received from the base station to the base station, and the base station determines the parameter change of the reference signal after passing through the channel according to the second parameter and the first parameter. Based on the same principle, the UE transmits the reference signal through the fourth parameter, the base station may transmit the third parameter received from the UE reference signal to the UE, and the UE determines the parameter change of the reference signal after passing through the channel according to the fourth parameter and the third parameter. Here, the received information of the reference signal after passing through the channel may include: the reference signal varies in parameters after passing through the channel.

Here, the location information of the UE may include geographical location information. The geographic location information may include: longitude and latitude, etc. The location information of the UE may also be relative location information with respect to a specific reference point, such as a base station. The relative positions may include: distance and/or orientation, etc.

The second UE may be a UE of known location information. There may be multiple second UEs. The location information of the different second UEs may be different or the same. The first UE and the second UE may be the same UE or different UEs.

Here, one or more reference signals associated with one second UE may be provided. For example, the second UE may receive a reference signal of a base station, and further obtain reception information of the reference signal; the second UE may receive multiple reference signals sent by one base station or multiple reference signals sent by multiple base stations respectively, so as to obtain receiving information corresponding to the multiple reference signals respectively. Similarly, the second UE may send a reference signal to a base station, so as to obtain receiving information of the reference signal; the second UE may send multiple reference signals to one base station or send reference signals to multiple base stations respectively, so as to obtain receiving information corresponding to the multiple reference signals respectively.

The location information of the second UE and the received information of one or more reference signals after passing through the channel when the second UE is in the location information may be used as training data of a set of positioning models. Second UE training data of different positions can be acquired, a training data set is established, and the positioning model is trained. The received information of the reference signal associated with the second UE after passing through the channel when the reference signal is in one position information is used as an input of the positioning model training, and the position information is used as an output of the positioning model training to train the positioning model.

For example, training data for a set of positioning models may include: the location information of the second UE and the received information of a reference signal after passing through the channel when the second UE is in the location information. The training data may also use the identification information to identify the base station to which the reference signal corresponds, etc.

The positioning model may be a machine learning model. The machine learning model may include that convolutional neural networks or the like are deep learning models. Model training may be performed in the communication device or in an electronic device other than the communication device. The positioning model after training can be deployed to a communication device for determining the location information of the first UE.

The location information of the first UE may be determined based on the received information of the reference signal associated with the first UE after passing through the channel using a positioning model that completes the training.

Here, the reference signal associated with the first UE may be the same type of reference signal as the reference signal used to train the positioning model. Therefore, the accuracy of the positioning model in determining the position information can be improved and the positioning accuracy can be improved by adopting the reasoning input close to the training data of the positioning model.

In this manner, the location information of the UE is determined based on the reception information of the reference signal associated with the UE through the positioning model. A positioning method is provided for realizing the positioning of UE.

Here, the positioning model may be trained for different UE bandwidth capabilities as training data. The positioning models corresponding to the UE bandwidth capabilities can be trained respectively for different UE bandwidth capabilities. When determining the first UE location information, a positioning model obtained by training the UE bandwidth capability of the first UE may be selected. For the UEs with different UE bandwidth capabilities, the correspondence between the received information and the position information of the reference signal after passing through the channel is different, so that the positioning accuracy can be further improved by adopting the positioning model corresponding to the UE bandwidth capability of the first UE.

In one possible implementation, the UE bandwidth capability of the first UE is the same as the UE bandwidth capability of the second UE. Namely: the positioning model for determining the first UE location information is trained using training data of a second UE having the same UE bandwidth capability as the first UE.

For example, the positioning model may be trained for 5MHz and 20MHz UE bandwidth capabilities, respectively. The location information of the second UE with the UE bandwidth capability of 5MHz and the receiving information of the reference signal after the reference signal passes through the channel can be acquired, a training data set is established, and a positioning model corresponding to the UE bandwidth capability of 5MHz is trained. A positioning model corresponding to the 20MHz UE bandwidth capability is trained in a similar manner. When the position information of the first UE (the bandwidth capability of the UE is 5 MHz) needs to be determined, a positioning model corresponding to the bandwidth capability of the 5MHz UE is selected to determine the position information of the first UE.

In one possible implementation, the operating bandwidth of the first UE is the same as the operating bandwidth of the second UE. Namely: the positioning model for determining the position information of the first UE is trained using training data of a second UE having the same operating bandwidth as the first UE.

The UE bandwidth capability of the UE refers to the maximum bandwidth that the UE can operate with, and the operating bandwidth of the UE is less than or equal to the UE bandwidth capability. For example, a positioning model for determining location information of a first UE operating at a first operating bandwidth is trained using training data of a second UE operating at a second operating bandwidth. Wherein the first operating bandwidth is equal to the second operating bandwidth.

For example, the UE bandwidth capability of the first UE is 5MHz, and the first UE is currently operating at a 5MHz operating bandwidth. The UE bandwidth capability of the second UE is 20MHz, while the second UE may also operate at an operating bandwidth of 5 MHz. The data (the reception information and the location information) of the second UE under the 5MHz operation bandwidth may be used as training data corresponding to the 5MHz operation bandwidth. A positioning model trained from this data may be used to determine location information for the first UE operating at the 5MHz operating bandwidth. In one possible implementation, a positioning model trained from this data may also be used to determine the location information of the first UE with a UE bandwidth capability greater than 5MHz and operating at a 5MHz operating bandwidth. Therefore, the positioning accuracy of the UE in the scene aiming at the specific working bandwidth is improved by adopting the corresponding positioning model aiming at the specific working bandwidth.

The positioning model may also be trained on bandwidths of different reference signals as training data. Namely: the positioning models corresponding to the bandwidths of the reference signals can be trained respectively for the bandwidths of the different reference signals. When determining the first UE location information, a positioning model obtained by training the bandwidth of the reference signal associated with the first UE may be selected. For bandwidths of different reference signals, the corresponding relation between the received information and the position information of the reference signals after the reference signals pass through the channels is different, so that the positioning accuracy can be further improved by adopting a positioning model corresponding to the bandwidths of the first UE associated reference signals. Here, the bandwidth of the reference signal may be a configuration bandwidth of the reference signal. The bandwidth of the reference signal may be configured for the UE by the network side device based on the UE bandwidth capability of the UE. In one possible implementation, the bandwidth of the reference signal configured by the network-side device for the UE is less than or equal to the UE bandwidth capability of the UE.

In one possible implementation, the bandwidth of the reference signal associated with the first UE is the same as the bandwidth of the reference signal associated with the second UE. Namely: the positioning model for determining the position information of the first UE is trained by using the received information of the reference signal associated with the second UE, which has the same bandwidth as the reference signal associated with the first UE, as training data.

For example, the positioning model may be trained for bandwidths of reference signals of 5MHz and 20MHz, respectively. The position information of the second UE with the bandwidth of the reference signal of 5MHz and the receiving information of the reference signal can be acquired, a training data set is established, and a positioning model corresponding to the bandwidth of the reference signal of 5MHz is trained. A positioning model of the bandwidth corresponding to the 20MHz reference signal is trained in a similar manner. When the position information of the first UE (the bandwidth of the associated reference signal is 5 MHz) needs to be determined, a positioning model corresponding to the bandwidth of the 5MHz reference signal is selected to determine the position information of the first UE. In one possible implementation, a second UE supporting a 20MHz operating frequency bandwidth may also use a reference signal bandwidth of 5 MHz; this data can then be used as training data for 5 MHz.

The positioning model may also be trained for different bandwidths for different reference signals and different UE bandwidth capabilities as training data. The positioning model corresponding to each collocation combination can be trained respectively aiming at various collocation combinations of bandwidths of different reference signals and different UE bandwidth capacities. When determining the first UE location information, a positioning model obtained by training the same combination of the bandwidth of the first UE associated reference signal and the UE bandwidth capability of the first UE may be selected. For bandwidths of different reference signals and UE bandwidth capabilities, the corresponding relation between the received information and the position information of the reference signals after passing through the channels is different, so that the positioning accuracy can be further improved by adopting a positioning model corresponding to the bandwidths of the first UE associated reference signals and the UE bandwidth capabilities.

In one possible implementation, the UE bandwidth capability of the first UE is the same as the UE bandwidth capability of the second UE, and the bandwidth of the reference signal associated with the first UE is the same as the bandwidth of the reference signal associated with the second UE. Namely: the positioning model for determining the first UE location information is trained using, as training data, received information of a reference signal associated with a second UE having the same bandwidth as the reference signal associated with the first UE, and the UE bandwidth capability of the second UE is the same as the UE bandwidth capability of the first UE.

For example, the positioning model a may be trained for a combination of the bandwidth of the 5MHz reference signal and the 5MHz UE bandwidth capability. Positioning model B is trained for a combination of the bandwidth of the reference signal of 5MHz and the bandwidth capability of the UE of 20 MHz. And establishing a training data set by using the position information of the second UE with the bandwidth capability of the 5MHz UE and the receiving information of the 5MHz reference signal, and training a positioning model A corresponding to the combination of the bandwidth of the 5MHz reference signal and the bandwidth capability of the 5MHz UE. A positioning model B of the bandwidth of the combined reference signal, the bandwidth of the 5MHz reference signal and the 20MHz UE bandwidth capability, is trained in a similar manner. When the position information of the first UE (the bandwidth of the reference signal is 5MHz and the bandwidth capability of the 5MHz UE) needs to be determined, the position information of the first UE is determined by selecting a positioning model corresponding to the combination of the bandwidth of the reference signal of 5MHz and the bandwidth capability of the 5MHz UE. Wherein, 20MHz UE bandwidth capability refers to supporting UEs operating at 20MHz bandwidth.

In this way, by training the positioning model for the UE bandwidth capability and/or the reference signal bandwidth and adopting the corresponding positioning model for the specific UE bandwidth capability and/or the reference signal bandwidth, the positioning accuracy of the UE in the scene of the specific UE bandwidth capability and/or the reference signal bandwidth is improved.

In one embodiment, when the UE bandwidth capability and/or the reference signal bandwidth of the first UE changes, a corresponding positioning model may be determined according to the updated UE bandwidth capability and/or the updated reference signal bandwidth of the first UE.

In one embodiment, the reference signal comprises: positioning reference signals PRS and/or sounding reference signals SRS. In one embodiment, the received information of the reference signal after passing through the channel may include: the parameter change of the positioning reference signal PRS after passing through a channel or the parameter change of the sounding reference signal SRS after passing through a channel.

Here, PRS and/or SRS may be uniformly employed for training of a positioning model and determining position information using the positioning model. The problem of reduced positioning accuracy caused by different reference signals used for training the positioning model and applying the positioning model is solved. Here, PRSs are typically transmitted by a base station to a UE and SRS are typically transmitted by the UE to the base station.

In one embodiment, the received information includes at least one of: channel impulse response, signal strength, signal angle, and time difference of arrival of the reference signal through different propagation paths.

When a signal is transmitted in a channel, the channel environment influence is received, and the channel impulse response, the signal strength, the signal angle and/or the arrival time difference of the reference signal passing through different propagation paths of the UE at different positions are different, namely the channel impulse response, the signal strength, the signal angle and/or the arrival time difference of the reference signal passing through different propagation paths are related to the position information of the UE. Here, the different propagation paths through which the reference signal passes may include different channels through which the reference signal passes, wherein the different channels may be channels between one UE and different base stations. The different propagation paths traversed by the reference signal may also include: different propagation environments within the same channel.

Thus, the received information may be used as input to a positioning model by which the location information of the UE is determined.

For example, in channel transmission, the contribution of a channel to the signal may be referred to as the channel response. The channel response may include: channel impulse response.

The channel impulse response may be a response output signal of the channel output terminal when one unit pulse signal is input to the channel. Because any input signal (i.e., the reference signal transmitted by the base station) can be decomposed into a linear superposition of unit pulse signals, the output signal (i.e., the reference signal received by the UE) can also be represented by a linear superposition of impulse responses.

The channel impulse response may include: the channel impulse response of the reference signal sent by the base station to the UE, and/or the channel impulse response of the reference signal sent by the UE to the base station.

Illustratively, in the OFDM system, a reference signal received by a UE after a reference signal transmitted by a base station passes through a multipath channel may be expressed by the expression (1):

Y＝HX+N (1)

wherein Y represents a reference signal received by the UE, X represents a reference signal transmitted by the base station, and H and N represent a channel matrix and additive Gaussian white noise respectively.

The estimated channel matrix can be expressed by expression (2):

from expression (2), a channel frequency response write H (f) can be obtained. H (f) is subjected to Inverse Fast Fourier Transform (IFFT) to obtain a channel impulse response.

The training data set of the positioning model includes channel impulse responses of the second UE with respect to the plurality of base stations at a bandwidth of a PRS, and location information, such as coordinates, of the second UE corresponding to each channel impulse response. For example, the positioning model may be trained and applied under a bandwidth of 20MHz or under a bandwidth of 5MHz supported by the RedCap UE.

And training the positioning model by taking PRS channel impulse responses of the second UE relative to the plurality of base stations as training input and taking coordinates of the second UE corresponding to the PRS channel impulse responses as training output.

A plurality of different models are trained based on different bandwidths supported by the second UE and/or different bandwidths of the reference signals.

The channel impulse response can more fully reflect the effect of the channel on the reference signal. Therefore, the channel impulse response is used as training data and reasoning data of the positioning model, so that the positioning accuracy can be improved.

The positioning model may determine, according to the received information corresponding to the reference signals between each base station and the first UE, the position information, such as the relative position relationship, of the first UE with respect to each base station.
