Description
本申请要求于2020年6月16日提交中国专利局,申请号为202010550800.6,发明名称为“通信方法、定位设备和终端设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on June 16, 2020, the application number is 202010550800.6, and the invention title is "communication method, positioning equipment and terminal equipment", the entire content of which is incorporated into this application by reference middle.
本申请涉及通信技术领域,尤其涉及一种通信方法、定位设备和终端设备。This application relates to the field of communication technology, and in particular to a communication method, positioning device and terminal device.
在新空口(New Radio,NR)定位中,要求高精度定位终端设备的位置。除了要求定位测量量的准确性之外,还要求该定位测量量来自于直射径,也称为视距(line of sight,LOS)。直射径表示无线信号由发射端直接到达接收端,而若无线信号遇到阻挡物产生了反射或散射再到达接收端,则被称为非直射径,也称为非视距(non line of sight,NLOS)。In New Radio (NR) positioning, high-precision positioning of terminal equipment is required. In addition to requiring the accuracy of the positioning measurement volume, it is also required that the positioning measurement volume comes from a direct radius, which is also called line of sight (LOS). The direct path means that the wireless signal arrives at the receiving end directly from the transmitting end, and if the wireless signal encounters obstructions and is reflected or scattered before reaching the receiving end, it is called a non-line of sight (non-line of sight). , NLOS).
目前,在上下行定位技术中,这里以下行定位技术为例进行说明。定位管理功能(location management function,LMF)网元接收终端设备上报的定位测量量;然后,LMF网元将该定位测量量认为是在传播路径处于LOS状态下测量得到的,并利用该定位测量量计算该终端设备的位置。At present, in the uplink and downlink positioning technology, the downlink positioning technology is described here as an example. The location management function (LMF) network element receives the location measurement value reported by the terminal device; then, the LMF network element considers the location measurement value to be measured when the propagation path is in the LOS state, and uses the location measurement value Calculate the location of the terminal device.
但是,当该定位测量量是在传播路径处于NLOS状态下测量得到的,而LMF网元仍认为该定位测量量是在该传播路径处于LOS状态下测量得到的,并通过该定位测量量计算该终端设备的位置,则会影响定位精度,导致定位精度较低。However, when the positioning measurement is measured when the propagation path is in the NLOS state, the LMF network element still considers the positioning measurement to be measured when the propagation path is in the LOS state, and calculates the positioning measurement based on the positioning measurement. The location of the terminal device will affect the positioning accuracy, resulting in low positioning accuracy.

为了提高终端设备的位置的定位精度,除了要求定位测量量的准确性之外,还要求该定位测量量来自于直射径,也称为LOS。下面对直射径和非直射径进行介绍。In order to improve the positioning accuracy of the position of the terminal device, in addition to the accuracy of the positioning measurement, it is also required that the positioning measurement comes from a direct radius, which is also called LOS. The following is an introduction to direct and non-direct fire diameters.

本申请实施例适用的场景包括但不限于:下行定位场景和上行定位场景。The applicable scenarios of the embodiments of the present application include, but are not limited to: downlink positioning scenarios and uplink positioning scenarios.
一、下行定位场景。1. Downlink positioning scenario.
终端设备对接入网设备发送的定位参考信号(positioning reference signal,PRS)进行测量,得到第一定位测量量。例如,该第一定位测量量可以是参考信号时间差(Reference signal time difference,RSTD)、出发角(angle of departure,AOD)、往返时间(round trip time,RTT)。终端设备通过长期演进系统定位协议(LTE positioning protocol,LPP)向定位设备发送提供位置信息消息(provide location information),该提供位置信息消息携带该第一定位测量量,再由定位设备根据该第一定位测量量对终端设备的位置进行定位计算。The terminal device measures the positioning reference signal (positioning reference signal, PRS) sent by the access network device to obtain the first positioning measurement quantity. For example, the first positioning measurement quantity may be reference signal time difference (RSTD), angle of departure (AOD), and round trip time (RTT). The terminal device sends a provide location information message (provide location information) to the positioning device through the long-term evolution positioning protocol (LTE positioning protocol, LPP). The location information message carries the first positioning measurement quantity, and the positioning device then sends the location information according to the first location information. The positioning measurement is used to perform positioning calculations on the position of the terminal device.
由于终端设备在下行传播路径处于NLOS状态时测量得到的定位测量量的准确性较低,若定位设备通过该终端设备在下行传播路径处于NLOS状态下测量得到的定位测量量进行定位计算,会影响定位精度,导致定位精度较低。其中,该下行传播路径为该接入网设备向该终端设备发送PRS的信号传播路径。Since the accuracy of the positioning measurement value measured by the terminal device when the downlink propagation path is in the NLOS state is low, if the positioning device uses the positioning measurement value measured by the terminal device when the downlink propagation path is in the NLOS state to perform the positioning calculation, it will affect Positioning accuracy, resulting in low positioning accuracy. Wherein, the downlink propagation path is a signal propagation path through which the access network device sends the PRS to the terminal device.
针对下行定位场景,本申请实施例所提供的如图2A所示的通信方法以实现向定位设备上报第一参数,该第一参数用于指示第一定位测量量所对应的第一传播条件。这样定位设备获取的定位测量量都有对应的NLOS状态指示或LOS状态指示,有益于提高定位精度。例如,第一定位测量是在该下行信号传播路径处于NLOS状态下测量得到的。由于在该下行信号传播路径处于NLOS状态时测量得到的定位测量量的准确度较低,那么定位设备在定位计算时可以排除该第一定位测量量,即只挑选在下行信号传播路径处于LOS状态下的定位测量量作定位计算,从而提高定位精度。For the downlink positioning scenario, the communication method shown in FIG. 2A provided by the embodiment of the present application realizes reporting the first parameter to the positioning device, and the first parameter is used to indicate the first propagation condition corresponding to the first positioning measurement. In this way, the positioning measurement quantity acquired by the positioning device has a corresponding NLOS status indicator or LOS status indicator, which is beneficial to improve the positioning accuracy. For example, the first positioning measurement is measured when the downlink signal propagation path is in the NLOS state. Since the accuracy of the positioning measurement value measured when the downlink signal propagation path is in the NLOS state is low, the positioning device can exclude the first positioning measurement value during the positioning calculation, that is, only select the downlink signal propagation path in the LOS state The following positioning measurement is used for positioning calculation, thereby improving positioning accuracy.

For example, the second positioning measurement quantity may be relative time of arrival (RTOA), angle of arrival (AOA), and round trip time (RTT). The access network device sends a measurement response (measurement response) message to the positioning device through the NR positioning protocol annex (NRPPa). The measurement response message carries the second positioning measurement quantity. The positioning measurement is used to perform positioning calculations on the position of the terminal device.
由于接入网设备在上行传播路径处于NLOS状态时测量得到的定位测量量的准确性较低,若定位设备通过该接入网设备在该上行传播路径处于NLOS状态下测量得到的定位测量量进行定位计算,会影响定位精度,导致定位精度较低。其中,该上行传播路径为该终端设备向接入网设备发送SRS的信号传播路径。Since the accuracy of the positioning measurement value measured by the access network device when the uplink propagation path is in the NLOS state is low, if the positioning device uses the positioning measurement value measured by the access network device when the uplink propagation path is in the NLOS state, The positioning calculation will affect the positioning accuracy, resulting in low positioning accuracy. Wherein, the uplink propagation path is a signal propagation path for the terminal device to send the SRS to the access network device.
针对该上行定位场景,本申请实施例所提供的图3所示的通信方法以实现向定位设备上报第二参数,该第二参数用于指示接入网设备的第二定位测量量所对应的第二传播条件。这样定位设备获取的定位测量量都有对应的NLOS状态指示或LOS状态指示,有益于提高定 位精度。例如,第二定位测量是在该上行信号传播路径处于NLOS状态下测量得到的。由于在该上行信号传播路径处于NLOS状态时测量得到的定位测量量的准确度较低,那么定位设备在定位计算时可以排除该第二定位测量量,即只挑选在上行信号传播路径处于LOS状态下的定位测量量作定位计算,从而提高定位精度。For this uplink positioning scenario, the communication method shown in FIG. 3 provided by the embodiment of the application realizes the reporting of the second parameter to the positioning device, and the second parameter is used to indicate the corresponding value of the second positioning measurement quantity of the access network device. Second propagation conditions. In this way, the positioning measurement obtained by the positioning device has a corresponding NLOS status indicator or LOS status indicator, which is beneficial to improve the positioning accuracy. For example, the second positioning measurement is measured when the uplink signal propagation path is in the NLOS state. Since the accuracy of the positioning measurement value measured when the uplink signal propagation path is in the NLOS state is low, the positioning device can exclude the second positioning measurement value during the positioning calculation, that is, only select the uplink signal propagation path in the LOS state The following positioning measurement is used for positioning calculation, thereby improving positioning accuracy.

201、终端设备测量接入网设备发送的第一参考信号,确定第一参数。201. A terminal device measures a first reference signal sent by an access network device, and determines a first parameter.
其中,该第一参数用于指示该终端设备的第一定位测量量对应的第一传播条件。第一传播条件为第一信号传播路径处于LOS状态,或者,该第一信号传播路径处于NLOS状态,该第一信号传播路径为接入网设备向终端设备发送第一参考信号的传播路径。Wherein, the first parameter is used to indicate the first propagation condition corresponding to the first positioning measurement quantity of the terminal device. The first propagation condition is that the first signal propagation path is in the LOS state, or the first signal propagation path is in the NLOS state, and the first signal propagation path is the propagation path through which the access network device sends the first reference signal to the terminal device.
例如,如图1A所示,第一信号传播路径为gNB向终端设备发送PRS的传播路径。终端设备对该gNB发送的PRS进行测量,得到第一定位测量量。若该第一定位测量量是在第一信号传播路径处于LOS状态下测量得到的,则该第一参数所指示的第一传播条件为该第一信号传播路径处于LOS状态;若该第一定位测量量是在该第一信号传播路径处于NLOS状态下测量得到的,则该第一参数所指示的第一传播条件为该第一信号传播路径处于NLOS状态。For example, as shown in FIG. 1A, the first signal propagation path is the propagation path through which the gNB sends the PRS to the terminal device. The terminal device measures the PRS sent by the gNB to obtain the first positioning measurement quantity. If the first positioning measurement is measured when the first signal propagation path is in the LOS state, the first propagation condition indicated by the first parameter is that the first signal propagation path is in the LOS state; if the first positioning The measured quantity is measured when the first signal propagation path is in the NLOS state, and the first propagation condition indicated by the first parameter is that the first signal propagation path is in the NLOS state.
可选地,第一参数携带的内容包括多种可能的形式,下面通过举例进行介绍。Optionally, the content carried by the first parameter includes multiple possible forms, which are introduced below by using examples.
实现方式一:第一参数包括如下信息中的一项或多项:第一信道状态指示、第一可靠度指示。Implementation manner 1: The first parameter includes one or more of the following information: a first channel state indicator and a first reliability indicator.
其中,第一信道状态指示用于指示第一定位测量量对应的第一传播条件,该第一可靠度指示用于表示对该第一参考信号的传播条件识别的可靠度。The first channel state indicator is used to indicate the first propagation condition corresponding to the first positioning measurement quantity, and the first reliability indicator is used to indicate the reliability of the propagation condition identification of the first reference signal.
在实现方式一中,该第一信道状态指示用于指示第一定位测量量对应的第一传播条件的指示方式包括多种,下面通过举例进行介绍。In the first implementation manner, the first channel state indication is used to indicate the first propagation condition corresponding to the first positioning measurement quantity, including multiple indicating manners, which will be introduced by using an example below.
指示方式一:终端设备通过提供位置信息消息是否携带有该第一信道状态指示以指示该第一传播条件。Indication mode 1: The terminal device indicates the first propagation condition by providing whether the location information message carries the first channel state indication.
基于指示方式一,下面示出两种可能的实现方式。Based on the instruction method one, two possible implementation methods are shown below.
第一种方式:当提供位置信息消息携带该第一信道状态指示时,第一传播条件为第一信号传播路径处于NLOS状态;当提供位置信息消息未携带该第一信道状态指示时,该第一传播条件为第一信号传播路径处于LOS状态。The first method: when the location information message carries the first channel state indicator, the first propagation condition is that the first signal propagation path is in the NLOS state; when the location information message does not carry the first channel state indicator, the first channel state indicator is A propagation condition is that the first signal propagation path is in the LOS state.
第二种方式:当提供位置信息消息携带该第一信道状态指示时,第一传播条件为第一信号传播路径处于LOS状态;当提供位置信息消息未携带该第一信道状态指示时,第一传播条件为第一信号传播路径处于NLOS状态。The second way: When the location information message carries the first channel state indicator, the first propagation condition is that the first signal propagation path is in the LOS state; when the location information message does not carry the first channel state indicator, the first propagation condition is The propagation condition is that the first signal propagation path is in the NLOS state.
指示方式二:终端设备通过第一信道状态指示所包括的第一数值指示该第一传播条件。Indication manner 2: The terminal device indicates the first propagation condition through the first value included in the first channel state indication.
基于指示方式二,下面示出三种可能的实现方式。Based on the second indication mode, three possible implementation modes are shown below.
第一种方式:当第一数值接近表征NLOS状态的取值N时,表示第一传播条件为第一信号传播路径处于NLOS状态;当第一数值接近表征LOS状态的取值M时,表示该第一传播条件为该第一信号传播路径处于LOS状态。其中,N,M均大于0。The first method: When the first value is close to the value N that characterizes the NLOS state, it means that the first propagation condition is that the first signal propagation path is in the NLOS state; when the first value is close to the value M that characterizes the LOS state, it means that The first propagation condition is that the first signal propagation path is in the LOS state. Among them, N and M are both greater than zero.
例如,该第一数值接近表征NLOS状态的取值N指该第一数值与N之间的差值小于或等 于第三预设阈值。该第一数值接近表征LOS状态的取值M指第一数值与M之间的差值小于或等于第三预设阈值。即“接近”可以理解为第一数值与表征第一信号传播路径的不同状态所对应的取值之间的差值小于或达到第三预设阈值。例如,表征NLOS状态的取值为6,如果所述第三预设阈值为0.5,那么当第一数值为5.6时,可以认为第一传播条件处于NLOS状态。For example, if the first value is close to the value N representing the NLOS state, it means that the difference between the first value and N is less than or equal to the third preset threshold. The first value close to the value M representing the LOS state means that the difference between the first value and M is less than or equal to the third preset threshold. That is, "close" can be understood as the difference between the first value and the values corresponding to different states of the first signal propagation path is less than or reaches the third preset threshold. For example, the value representing the NLOS state is 6, and if the third preset threshold value is 0.5, then when the first value is 5.6, it can be considered that the first propagation condition is in the NLOS state.
具体的,第一种方式是通过第一数值与表征NLOS状态的取值N的接近程度指示该第一传播条件;或者是,通过第一数值与表征LOS状态的取值M的接近程度指示该第一传播条件。Specifically, the first way is to indicate the first propagation condition by the closeness of the first value to the value N representing the NLOS state; or, to indicate the first propagation condition by the closeness of the first value to the value M representing the LOS state The first propagation condition.
第二种方式:当第一数值接近表征NLOS状态的取值N时,表示第一传播条件为第一信号传播路径处于NLOS状态;当第一数值不接近表征NLOS状态的取值N时,表示第一传播条件为第一信号传播路径处于LOS状态。其中,N大于0。The second way: when the first value is close to the value N representing the NLOS state, it means that the first propagation condition is that the first signal propagation path is in the NLOS state; when the first value is not close to the value N representing the NLOS state, it means The first propagation condition is that the first signal propagation path is in the LOS state. Among them, N is greater than zero.
具体的,第二种方式与第一种方式类似,具体可以参阅第一种方式中对第一数值接近表征NLOS状态的取值N的相关说明。第二种方式与第一种方式不同的地方在于:第二种方式中仅设定了表征NLOS状态的取值N,当第一数值接近表征NLOS状态的取值N时,表示第一传播条件为第一信号传播路径处于NLOS状态。而当第一数值不接近表征NLOS状态的取值N时,则表示第一传播条件为第一信号传播路径处于LOS状态。而该第一数值不接近表征NLOS状态的取值N可以指该第一数值与表征NLOS状态的取值N的差值大于第三预设阈值。Specifically, the second method is similar to the first method. For details, please refer to the related description of the first method that the first value is close to the value N representing the NLOS state. The difference between the second method and the first method is that in the second method, only the value N representing the NLOS state is set. When the first value is close to the value N representing the NLOS state, it represents the first propagation condition The first signal propagation path is in the NLOS state. When the first value is not close to the value N representing the NLOS state, it indicates that the first propagation condition is that the first signal propagation path is in the LOS state. The fact that the first value is not close to the value N representing the NLOS state may mean that the difference between the first value and the value N representing the NLOS state is greater than the third preset threshold.
第三种方式:当第一数值接近表征LOS状态的取值M时,表示该第一传播条件为该第一信号传播路径处于LOS状态;当第一数值不接近表征LOS状态的取值M时,表示该第一传播条件为该第一信号传播路径处于NLOS状态。其中,M大于0。The third way: when the first value is close to the value M that characterizes the LOS state, it means that the first propagation condition is that the first signal propagation path is in the LOS state; when the first value is not close to the value M that characterizes the LOS state , Indicating that the first propagation condition is that the first signal propagation path is in the NLOS state. Among them, M is greater than zero.
具体的,第三种方式与第二种方式类似,具体可以参阅第一种方式中对第一数值接近表征LOS状态的取值M的相关说明。第三种方式与第二种方式不同的地方在于,第三种方式中仅设定了表征LOS状态的取值M,当第一数值接近表征LOS状态的取值M时,表示该第一传播条件为该第一信号传播路径处于LOS状态;而当第一数值不接近表征LOS状态的取值M时,则表示该第一传播条件为该第一信号传播路径处于NLOS状态。而该第一数值不接近表征LOS状态的取值M可以指该第一数值与表征LOS状态的取值M的差值大于第三预设阈值。Specifically, the third method is similar to the second method. For details, please refer to the related description of the first method that the first value is close to the value M representing the LOS state. The difference between the third method and the second method is that in the third method, only the value M representing the LOS state is set. When the first value is close to the value M representing the LOS state, it indicates the first propagation The condition is that the first signal propagation path is in the LOS state; and when the first value is not close to the value M representing the LOS state, it means that the first propagation condition is that the first signal propagation path is in the NLOS state. The fact that the first value is not close to the value M representing the LOS state may mean that the difference between the first value and the value M representing the LOS state is greater than the third preset threshold.
指示方式三:终端设备通过第一信道状态指示所包括的第一比值指示该第一传播条件。Indication mode 3: The terminal device indicates the first propagation condition through the first ratio included in the first channel state indication.
基于指示方式三,下面示出两种可能的实现方式。Based on indication mode three, two possible implementation modes are shown below.
第一种方式:当该第一比值大于或等于第一预设比值时,该第一传播条件为该第一信号传播路径处于NLOS状态;当该第一比值小于该第一预设比值时,该第一传播条件为该第一信号传播路径处于LOS状态。The first method: when the first ratio is greater than or equal to the first preset ratio, the first propagation condition is that the first signal propagation path is in the NLOS state; when the first ratio is less than the first preset ratio, The first propagation condition is that the first signal propagation path is in the LOS state.
具体的,当该第一比值越大,表征该第一传播条件为该第一信号传播路径处于NLOS状态的可能性越高;当该第一比值越小,表征该第一传播条件该第一信号传播路径处于LOS状态的可能性越低。Specifically, when the first ratio is larger, the probability that the first propagation condition is that the first signal propagation path is in the NLOS state is higher; when the first ratio is smaller, the first propagation condition is the first propagation condition. The lower the probability that the signal propagation path is in the LOS state.
例如,该第一比值越大可以理解为该第一比值大于或等于第一预设比值,此时认为该 第一信号传播路径处于NLOS状态。该第一比值越小可以理解为该第一比值小于第一预设比值,此时认为该第一传播条件该第一信号传播路径处于LOS状态。For example, the larger the first ratio can be understood as the first ratio is greater than or equal to the first preset ratio, and the first signal propagation path is considered to be in the NLOS state at this time. The smaller the first ratio may be understood to mean that the first ratio is less than the first preset ratio. At this time, the first signal propagation path is considered to be in the LOS state under the first propagation condition.
第二种方式:当该第一比值大于或等于第一预比值时,该第一传播条件为该第一信号传播路径处于LOS状态;当该第一比值小于该第一预设比值时,该第一传播条件为该第一信号传播路径处于NLOS状态。The second method: when the first ratio is greater than or equal to the first pre-ratio, the first propagation condition is that the first signal propagation path is in the LOS state; when the first ratio is less than the first preset ratio, the The first propagation condition is that the first signal propagation path is in the NLOS state.
具体的,当该第一比值越大,表征该第一传播条件该第一信号传播路径处于LOS状态的可能性越高;当该第一比值越小,表征该第一传播条件为该第一信号传播路径处于NLOS状态的可能性越低。Specifically, when the first ratio is larger, the probability that the first signal propagation path is in the LOS state is higher, which characterizes the first propagation condition; when the first ratio is smaller, it means that the first propagation condition is the first propagation condition. The signal propagation path is less likely to be in the NLOS state.
例如,该第一比值越大可以理解为该第一比值大于或等于第一预设比值,此时认为该第一信号传播路径处于LOS状态。该第一比值越小可以理解为第一比值小于该第一预设比值,此时认为该第一信号传播路径处于NLOS状态。For example, the larger the first ratio can be understood as the first ratio is greater than or equal to the first preset ratio, and the first signal propagation path is considered to be in the LOS state at this time. The smaller the first ratio is, it can be understood that the first ratio is smaller than the first preset ratio. At this time, the first signal propagation path is considered to be in the NLOS state.
在实现方式一中,该第一可靠度指示用于表示对第一参考信号的传播条件识别的可靠度的方式包括多种,下面通过举例进行介绍。In the first implementation manner, the first reliability indicator is used to indicate the reliability of the recognition of the propagation condition of the first reference signal including multiple methods, which are introduced below by using examples.
方式1:该第一可靠度指示包括第二数值;当该第二数值大于或等于第一预设阈值时,表示对该第一参考信号的传播条件的识别的可靠度较高;当该第二数值小于第一预设阈值时,表示对该第一参考信号的传播条件的识别的可靠度较低。Manner 1: The first reliability indicator includes a second value; when the second value is greater than or equal to the first preset threshold, it means that the recognition of the propagation condition of the first reference signal has a higher reliability; When the two values are less than the first preset threshold, it indicates that the reliability of the identification of the propagation condition of the first reference signal is low.
方式2:该第一可靠度指示包括第二比值。当该第二比值大于或等于第二预设比值时,表示对该第一参考信号的传播条件的识别的可靠度较高;当该第二比值小于第二预设比值时,表示对该第一参考信号的传播条件的识别的可靠度较低。Manner 2: The first reliability indicator includes a second ratio. When the second ratio is greater than or equal to the second preset ratio, it means that the recognition of the propagation condition of the first reference signal is more reliable; when the second ratio is less than the second preset ratio, it means that the first reference signal is less reliable. The reliability of the identification of the propagation condition of a reference signal is low.
上述示出了通过数值或比值指示可靠度的高低,本申请实施例还可以通过其他表示方式,具体不做限定。例如,该第一可靠度指示包括“1”或者“0”,“1”指示可靠度较高,“0”指示可靠度较低。The foregoing shows that the reliability level is indicated by a numerical value or a ratio, and the embodiment of the present application may also be expressed in other ways, which is not specifically limited. For example, the first reliability indicator includes "1" or "0", "1" indicates higher reliability, and "0" indicates lower reliability.
在该实现方式一中,终端设备先确定该第一定位测量量所对应的第一传播条件,具体的确定方式与步骤203中定位设备基于步骤201的实现方式二下的确定方式和/或步骤203中定位设备基于步骤201的实现方式三的确定方式类似,具体请参阅步骤203中的相关介绍,此处不再介绍。In the first implementation manner, the terminal device first determines the first propagation condition corresponding to the first positioning measurement. The specific determination method is the same as the determination method and/or step of the positioning device in step 203 based on the second implementation manner of step 201 The determination method of the positioning device in 203 based on the implementation manner 3 of step 201 is similar. For details, please refer to the related introduction in step 203, which will not be described here.
实现方式二:第一参数包括P个第一信号强度值。Implementation manner 2: The first parameter includes P first signal strength values.
其中,该第一信号强度值为RSRP或RSSI或RSRQ,P为大于或等于3的整数。Wherein, the first signal strength value is RSRP or RSSI or RSRQ, and P is an integer greater than or equal to 3.
具体的,P个第一信号强度值为终端设备在一段时长内P次接收接入网设备发送的第一参考信号分别所对应的P个信号强度值。Specifically, the P first signal strength values are P signal strength values corresponding to the first reference signal sent by the access network device that the terminal device receives P times within a period of time.
可选的,该第一参考信号为PRS,第一信号强度值为终端设备接收接入网设备发送的PRS的RSRP或RSSI或RSRQ。Optionally, the first reference signal is a PRS, and the first signal strength value is the RSRP or RSSI or RSRQ of the PRS sent by the access network device received by the terminal device.
在实现方式二中,可选的,该第一参数还包括以下信息中的一项或多项:In the second implementation manner, optionally, the first parameter further includes one or more of the following information:
P个第一时间值,第一测量时长,第一测量周期。P first time values, first measurement duration, and first measurement period.
其中,该P个第一时间值与P个第一信号强度值一一对应,该第一时间值用于表示测量得到该第一信号强度值的时刻。该第一测量时长用于表示测量得到该P个第一信号强度值所需的时长,该第一测量周期用于表示测量该第一信号强度值的周期。Wherein, the P first time values correspond to P first signal strength values in a one-to-one correspondence, and the first time value is used to indicate the moment when the first signal strength value is obtained by measurement. The first measurement duration is used to indicate the duration required to obtain the P first signal strength values by measurement, and the first measurement period is used to indicate the period for measuring the first signal strength value.
下面结合表1对P个第一时间值与P个第一信号强度值一一对应进行说明。其中,表1中的示例,P为8。The following describes the one-to-one correspondence between P first time values and P first signal strength values in conjunction with Table 1. Among them, in the example in Table 1, P is 8.
表1Table 1
由表1可知,每个第一信号强度值都有唯一对应的一个第一时间值。例如,强度值A是在零时第1个毫秒时测量得到的。It can be seen from Table 1 that each first signal strength value has a uniquely corresponding first time value. For example, the intensity value A is measured at the first millisecond of zero time.
下面结合图2B对第一测量时长和第一测量周期进行说明。由图2B可知,第一信号强度值的测量周期为10ms(毫秒),即终端设备测量第一参考信号的测量周期为10ms。那么针对该P个第一信号强度值来说,第一测量周期为10ms。而终端设备测量得到该P个第一信号强度值所需的时长为第一测量时长,由图2B可知,该第一测量时长为80ms。The first measurement duration and the first measurement period will be described below in conjunction with FIG. 2B. It can be seen from FIG. 2B that the measurement period of the first signal strength value is 10 ms (milliseconds), that is, the measurement period of the terminal device measuring the first reference signal is 10 ms. Then for the P first signal strength values, the first measurement period is 10 ms. The time required for the terminal device to measure the P first signal strength values is the first measurement time. As can be seen from FIG. 2B, the first measurement time is 80 ms.
需要说明的是,图2B所示的第一测量时长是P个第一信号强度值所对应的第一测量周期的个数相加得到的时长。在实际应用中,该第一测量时长也可以是根据实际测量得到该P个第一信号强度值的P个第一时间值来确定。例如,如表1所示,该第一测量时长为零时第1个毫秒与零时第75个毫秒之间的时间间隔,即第一测量时长为75ms。It should be noted that the first measurement duration shown in FIG. 2B is the duration obtained by adding the number of first measurement periods corresponding to P first signal strength values. In practical applications, the first measurement duration may also be determined based on P first time values of the P first signal strength values obtained by actual measurement. For example, as shown in Table 1, the first measurement duration is the time interval between the first millisecond at zero time and the 75th millisecond at zero time, that is, the first measurement duration is 75 ms.
实现方式三:第一参数包括第一信道状态参数。Implementation manner 3: The first parameter includes the first channel state parameter.
该第一信道状态参数包括以下参数中的一项或多项:The first channel state parameter includes one or more of the following parameters:

Among them, the skewness is also called the third order distance, the kurtosis is also called the fourth order distance, and the H skewness is also called the fifth order distance.
其中,该第一参考信号的峰值概率指该P个第一信号强度值中的峰值出现的概率。可选的,第一参考信号为PRS。Wherein, the peak probability of the first reference signal refers to the probability of a peak in the P first signal strength values. Optionally, the first reference signal is PRS.
具体的,该第一参考信号的标准差、峰值概率、偏度、峰度和H偏度可以是利用实现方式二中的P个第一信号强度值分别计算得到的。Specifically, the standard deviation, peak probability, skewness, kurtosis, and H skewness of the first reference signal may be calculated by using the P first signal strength values in the second implementation manner.
下面分别对该第一信道状态参数所包括的参数的计算方式进行介绍:The calculation methods of the parameters included in the first channel state parameter are respectively introduced below:
1、第一参考信号的标准差 1. The standard deviation of the first reference signal
2、第一参考信号的峰值概率。2. The peak probability of the first reference signal.
例如,P个第一信号强度值,其中P为8,峰值出现两次,则该第一参考信号的峰值概率为25%。For example, P first signal strength values, where P is 8, and the peak value appears twice, then the peak probability of the first reference signal is 25%.
3、偏度 3. Skewness
4、峰度 4. Kurtosis
5、H偏度 5. H skewness
其中,σ 1为第一参考信号的标准差,x i为第i个第一信号强度值,μ 1为该P个第一信号强度值的均值, 指对第1个至第n个(x i-μ 1) 3进行求和, 指对第1个至第n个(x i-μ 1) 4进行求和, 指对第1个至第n个(x i-μ) 5进行求和,n等于P。 Where σ 1 is the standard deviation of the first reference signal, x i is the i-th first signal strength value, μ 1 is the average value of the P first signal strength values, Refers to the summation of the 1st to the nth (x i -μ 1 ) 3, Refers to the summation of the 1st to the nth (x i -μ 1 ) 4, Refers to the summation of the 1st to nth (x i -μ) 5 , n is equal to P.

The content carried by the first parameter has many possible forms. For details, please refer to the relevant description in the foregoing step 201, which will not be repeated here.
可选的,该提供位置信息消息携带该第一定位测量量。即终端设备将第一定位测量量和第一参数一起上报给定位设备。Optionally, the provide location information message carries the first location measurement quantity. That is, the terminal device reports the first positioning measurement quantity and the first parameter together to the positioning device.

由于指示方式二中包括三种可能的实现方式,下面结合步骤201提供的指示方式二中的第一种方式至第三种方式分别介绍步骤203。Since the second indication method includes three possible implementation modes, step 203 will be separately introduced in the following in combination with the first to third modes of the second indication method provided in step 201.

The difference between the value and N and M respectively is used to determine the first propagation condition, which is not specifically limited in this application.
b、基于步骤201提供的指示方式二中的第二种方式,步骤203具体包括:b. Based on the second mode of the instruction mode two provided in step 201, step 203 specifically includes:

If so, the positioning device determines that the first propagation condition is that the first signal propagation path is in the LOS state; if not, then The positioning device determines that the first propagation condition is that the first signal propagation path is in the NLOS state.
3、基于步骤201的实现方式一中的指示方式三介绍步骤203。3. The step 203 is introduced based on the instruction method three in the first implementation method of step 201.
a、基于步骤201提供的指示方式三中的第一种方式,步骤203具体包括:a. Based on the first method of the third instruction method provided in step 201, step 203 specifically includes:
当该定位设备确定第一比值大于或等于第一预设比值时,该定位设备确定该第一传播条件为第一信号传播路径处于NLOS状态;当该定位设备确定第一比值小于第一预设比值时,该定位设备确定该第一传播条件为第一信号传播路径处于LOS状态。When the positioning device determines that the first ratio is greater than or equal to the first preset ratio, the positioning device determines that the first propagation condition is that the first signal propagation path is in the NLOS state; when the positioning device determines that the first ratio is less than the first preset ratio When the ratio is higher, the positioning device determines that the first propagation condition is that the first signal propagation path is in the LOS state.
b、基于步骤201提供的指示方式三中的第二种方式,步骤203具体包括:b. Based on the second method of the third instruction method provided in step 201, step 203 specifically includes:
当该第一比值大于或等于第一预设比值时,该定位设备确定该第一传播条件为第一信号传播路径处于LOS状态;当该第一比值小于该第一预设比值时,该定位设备确定该第一传播条件为第一信号传播路径处于LOS状态。When the first ratio is greater than or equal to the first preset ratio, the positioning device determines that the first propagation condition is that the first signal propagation path is in the LOS state; when the first ratio is less than the first preset ratio, the positioning device The device determines that the first propagation condition is that the first signal propagation path is in the LOS state.
上述示出了定位设备根据该第一信道状态指示确定第一定位测量量对应的第一传播条件的多种方式。可选的,定位设备根据该第一可靠度指示进一步确定对该第一参考信号的传播条件的识别的可靠度,当可靠度较高时,定位设备可以进一步确定该第一定位测量量对应的该第一传播条件。The foregoing shows multiple ways for the positioning device to determine the first propagation condition corresponding to the first positioning measurement quantity according to the first channel state indication. Optionally, the positioning device may further determine the reliability of the identification of the propagation condition of the first reference signal according to the first reliability indication. When the reliability is high, the positioning device may further determine the value corresponding to the first positioning measurement quantity. The first propagation condition.
具体的,在实现方式一中,该第一可靠度指示通过两种可能的形式指示,下面分别进行介绍。Specifically, in the first implementation manner, the first reliability indication is indicated in two possible forms, which will be introduced separately below.
方式1:第一可靠度指示包括第二数值。当该定位设备确定第二数值大于或等于第一预设阈值时,该定位设备确定该第一传播条件的识别的可靠度较高;当该定位设备确定该第二数值小于第一预设阈值时,该定位设备确定该第一传播条件的识别的可靠度较低。Manner 1: The first reliability indicator includes the second value. When the positioning device determines that the second value is greater than or equal to the first preset threshold, the positioning device determines that the recognition of the first propagation condition is more reliable; when the positioning device determines that the second value is less than the first preset threshold At this time, the positioning device determines that the reliability of the recognition of the first propagation condition is low.
方式2:该第一可靠度指示包括第二比值。当该定位设备确定第二比值大于或等于第二预设比值时,该定位设备确定该第一传播条件的识别的可靠度较高;当该定位设备确定该第二比值小于第二预设比值时,该定位设备确定该第一传播条件的识别的可靠度较低。Manner 2: The first reliability indicator includes a second ratio. When the positioning device determines that the second ratio is greater than or equal to the second preset ratio, the positioning device determines that the recognition of the first propagation condition is more reliable; when the positioning device determines that the second ratio is less than the second preset ratio At this time, the positioning device determines that the reliability of the recognition of the first propagation condition is low.
由此可知,定位设备获取到每个定位测量量都有对应的NLOS状态指示或LOS状态指示,即定位设备获得有益于提高定位精度的更多信息。From this, it can be seen that each positioning measurement obtained by the positioning device has a corresponding NLOS status indicator or LOS status indicator, that is, the positioning device obtains more information that is beneficial to improving the positioning accuracy.
二、基于步骤201的实现方式二介绍步骤203。2. Step 203 is introduced based on the second implementation of step 201.
基于实现方式二,定位设备确定该第一定位测量量对应的传播条件包括以下两种方式,下面分别进行介绍:Based on the second implementation manner, the positioning device determines the propagation condition corresponding to the first positioning measurement quantity including the following two methods, which are respectively introduced below:
方式1:定位设备基于第一分布特征确定该第一定位测量量对应的第一传播条件,该第一分布特征为该P个第一信号强度值中的部分或全部第一信号强度值的概率的分布特征。Manner 1: The positioning device determines the first propagation condition corresponding to the first positioning measurement based on the first distribution feature, where the first distribution feature is the probability of some or all of the P first signal strength values The distribution characteristics.
基于方式1,步骤203包括步骤203a。Based on method 1, step 203 includes step 203a.
步骤203a:定位设备根据该第一分布特征确定该第一定位测量量对应的第一传播条件。Step 203a: The positioning device determines a first propagation condition corresponding to the first positioning measurement quantity according to the first distribution characteristic.
其中,第一信号强度值的概率指该第一信号强度在该P个第一信号强度值中出现的概率。而该第一信号强度值的概率的计算方式有多种,下面通过举例说明。Wherein, the probability of the first signal strength value refers to the probability of the first signal strength appearing in the P first signal strength values. There are many ways to calculate the probability of the first signal strength value, which will be described below with an example.
例如,针对信号强度值A的概率,第一信号强度值一共包括P个,该P个第一信号强度值中包括L个信号强度值为A的第一信号强度值,那么可知信号强度值A的概率为L/P。其中,L大于0。For example, for the probability of the signal strength value A, the first signal strength value includes a total of P, and the P first signal strength values include L first signal strength values whose signal strength value is A, then the signal strength value A can be known The probability of is L/P. Among them, L is greater than zero.
再例如,针对信号强度值A的概率,P个第一信号强度值分别为A、A、B、B、C,则可知信号强度值为A的第一信号强度值数量为2,那么可知信号强度值A的概率为40%。For another example, for the probability of the signal strength value A, the P first signal strength values are A, A, B, B, and C respectively, and then the number of first signal strength values with the signal strength value of A is 2, then the signal The probability of intensity value A is 40%.
本实施例中,定位设备可以只采用该P个第一信号强度值中的部分第一信号强度值的概率的分布特征确定该第一传播条件。In this embodiment, the positioning device may only use the probability distribution characteristics of some of the P first signal strength values to determine the first propagation condition.
例如,当该P个第一信号强度值出现远小于其他第一信号强度值的Q个第一信号强度值,定位设备可以排除该P个第一信号强度中的该Q个第一信号强度值,并使用该剩余的P-Q个第一信号强度值确定该第一传播条件。其中,Q大于或等于1且小于P的整数。For example, when the P first signal strength values appear Q first signal strength values that are much smaller than other first signal strength values, the positioning device may exclude the Q first signal strength values among the P first signal strength values , And use the remaining PQ first signal strength values to determine the first propagation condition. Among them, Q is an integer greater than or equal to 1 and less than P.
可选的,该第一参数还包括以下信息中的一项或多项:P个第一时间值,第一测量时长,第一测量周期。因此,定位设备可以根据该第一参数携带的与该P个第一信号强度值相关的时间参数和该P个第一信号强度值判断是否只采用该P个第一信号强度值的部分第一信号强度的概率的分布特征确定该第一传播条件。例如,该第一测量时长较长,且P个第一时间值中相邻的两个时间值较大,则定位设备可以采用P个第一信号强度值的部分第一信号强度值的概率的分布特征确定该第一传播条件。该部分第一信号强度值所对应的测量时长较短,且相邻两个第一信号强度值所对应的第一时间值的时间间隔较小。Optionally, the first parameter further includes one or more of the following information: P first time values, first measurement duration, and first measurement period. Therefore, the positioning device can determine whether to use only part of the P first signal strength values based on the time parameters related to the P first signal strength values carried by the first parameter and the P first signal strength values. The distribution characteristic of the probability of the signal strength determines the first propagation condition. For example, if the first measurement time is longer, and the two adjacent time values among the P first time values are larger, the positioning device can use the probability of a part of the first signal strength values of the P first signal strength values. The distribution characteristics determine the first propagation condition. The measurement duration corresponding to this part of the first signal strength value is relatively short, and the time interval between the first time values corresponding to two adjacent first signal strength values is relatively small.
下面以定位设备根据该P个第一信号强度值中的全部第一信号强度值的概率的分布特征确定该第一传播条件为例介绍上述步骤203a。且步骤203a具体包括步骤1至步骤3。The above step 203a is described below by taking the positioning device determining the first propagation condition according to the distribution characteristics of the probability of all the first signal strength values in the P first signal strength values as an example. And step 203a specifically includes step 1 to step 3.
步骤1:判断第一相似度是否高于第二相似度,若是,则执行步骤2;若否,则执行步骤3。Step 1: Determine whether the first degree of similarity is higher than the second degree of similarity, if yes, go to step 2; if not, go to step 3.
其中,第一相似度为该P个第一信号强度值的概率的分布特征与第一预设分布特征之间的相似度。该第二相似度为该P个第一信号强度值的概率的分布特征与第二预设分布特征之间的相似度。该第一预设分布特征为终端设备在该第一传播路径处于LOS状态下测量得到的第一历史信号强度值的概率的分布特征。该第二预设分布特征为该终端设备在该第一传播路径处于NLOS状态下测量得到的第二历史信号强度值的概率的分布特征。Wherein, the first degree of similarity is the degree of similarity between the distribution feature of the probability of the P first signal strength values and the first preset distribution feature. The second similarity is the similarity between the distribution feature of the probability of the P first signal strength values and the second preset distribution feature. The first preset distribution feature is a distribution feature of the probability of the first historical signal strength value measured by the terminal device when the first propagation path is in the LOS state. The second preset distribution feature is a distribution feature of the probability of the second historical signal strength value measured by the terminal device when the first propagation path is in the NLOS state.
一种可能的实现方式中,第一相似度通过该P个第一信号强度值的概率的分布特征与第一参考模型之间的第一拟合度表征,该第二相似度通过该P个第一信号强度值的概率的分布特征与第二参考模型之间的第二拟合度表征。In a possible implementation manner, the first degree of similarity is characterized by the first degree of fit between the probability distribution characteristics of the P first signal strength values and the first reference model, and the second degree of similarity is characterized by the P number of The second degree of fit characterization between the distribution feature of the probability of the first signal strength value and the second reference model.
该第一参考模型用于表征该第一预设分布特征,该第二参考模型用于表征该第二参考模型。一种可能的实现方式中,该第一拟合度还用于表征第一传播条件为该第一传播路径处于LOS状态的识别可靠度,该第二拟合度还用于表征第一传播条件为该第一传播路径处于NLOS状态的识别可靠度。The first reference model is used to characterize the first preset distribution feature, and the second reference model is used to characterize the second reference model. In a possible implementation manner, the first degree of fit is also used to characterize the first propagation condition as the recognition reliability that the first propagation path is in the LOS state, and the second degree of fit is also used to characterize the first propagation condition. It is the recognition reliability that the first propagation path is in the NLOS state.
可选的,该第一拟合度通过第一对数似然表征,该第二拟合度通过第二对数似然表征。当第一对数似然大于第二对数似然,表征第一拟合度大于第二拟合度,即表征第一相似度高于第二相似度。Optionally, the first degree of fit is characterized by a first log-likelihood, and the second degree of fit is characterized by a second log-likelihood. When the first log likelihood is greater than the second log likelihood, it indicates that the first degree of fit is greater than the second degree of fit, that is, it indicates that the first degree of similarity is higher than the second degree of similarity.
具体的,由历史信号强度值和多次实验确定:当第一传播路径处于LOS状态时,历史信号强度值的概率的分布特征符合韦尔布分布(Weibull)模型;当第一传播路径处于NLOS状态时,历史信号强度值的概率的分布特征符合高斯分布模型。Specifically, it is determined by historical signal strength values and multiple experiments: when the first propagation path is in the LOS state, the probability distribution characteristics of the historical signal strength values conform to the Weibull model; when the first propagation path is in NLOS In the state, the distribution characteristics of the probability of the historical signal strength value conform to the Gaussian distribution model.
具体的,定位设备可以通过第一传播路径处于LOS状态时测量得到的第一历史信号强度值和该第一历史信号强度值的概率拟合该韦尔布分布(Weibull)模型;定位设备可以通过第一传播路径处于NLOS状态时测量得到的第二历史信号强度值和该第二历史信号强度值的概率拟合该高斯分布模型,具体拟合过程后续再进行介绍。Specifically, the positioning device can fit the Weibull model by using the first historical signal strength value measured when the first propagation path is in the LOS state and the probability of the first historical signal strength value; the positioning device can use The second historical signal strength value measured when the first propagation path is in the NLOS state and the probability of the second historical signal strength value fit the Gaussian distribution model, and the specific fitting process will be introduced later.
因此,该第一参考模型可以为韦尔布分布(Weibull)模型,第二参考模型可以为高斯分布模型。那么,第一对数似然 第二对数似然 Therefore, the first reference model may be a Weibull distribution model, and the second reference model may be a Gaussian distribution model. Well, the first log likelihood Second log likelihood
其中,函数 为韦尔布分布模型,函数 为高斯分布模型。x n指第n个第一信号强度值,logf w(x n)为对数函数,指以10为底求f w(x n)的对数, 指对第1个至第P个logf w(x n)进行求和, 指对第1个至第P个logf G(x n)进行求和。 Among them, the function Is the Weilb distribution model, the function It is a Gaussian distribution model. x n refers to the n-th first signal strength value, logf w (x n ) is a logarithmic function, refers to finding the logarithm of f w (x n) with 10 as the base, Refers to the summation of the 1st to Pth logf w (x n ), Refers to the summation of the 1st to Pth logf G (x n ).
当 时,说明该P个第一信号强度值的概率的分布特征与Weibull分布模型的拟合度更高,则执行步骤2;当 时,说明该P个第一信号强度值的概率的分布特征与高斯分布的拟合度更高,则执行步骤3。 when , It means that the distribution characteristics of the probability of the P first signal intensity values have a higher degree of fit with the Weibull distribution model, then go to step 2; If the distribution characteristics of the probability of the P first signal intensity values have a higher degree of fit with the Gaussian distribution, then step 3 is performed.
步骤2:该定位设备确定第一传播条件为该第一信号传播路径处于LOS状态。Step 2: The positioning device determines that the first propagation condition is that the first signal propagation path is in the LOS state.
当该第一对数似然 大于或等于第二对数似然 时,该定位设备确定该第一传播条件为该第一信号传播路径处于LOS状态。 When the first log likelihood Greater than or equal to the second log likelihood At this time, the positioning device determines that the first propagation condition is that the first signal propagation path is in the LOS state.
步骤3:该定位设备确定该第一传播条件为该第一信号传播路径处于NLOS状态。Step 3: The positioning device determines that the first propagation condition is that the first signal propagation path is in the NLOS state.
当该第一对数似然 小于第二对数似然 时,该定位设备确定该第一传播条件为该第 一信号传播路径处于NLOS状态。 When the first log likelihood Less than the second log likelihood At this time, the positioning device determines that the first propagation condition is that the first signal propagation path is in the NLOS state.
下面分别介绍定位设备拟合第一参考模型和第二参考模型的过程。The following describes the process of fitting the first reference model and the second reference model by the positioning device.
一、介绍定位设备拟合第一参考模型的过程,下面通过步骤a至步骤c进行说明。1. Introduce the process of fitting the first reference model by the positioning device, which will be described below through step a to step c.
步骤a:定位设备将该第一历史信号强度值的作为横坐标,将该第一历史信号强度值的概率作为纵坐标,得到该第一历史信号强度值的概率分布图。例如,横坐标为RSSI,纵坐标为该RSSI的概率。Step a: The positioning device uses the first historical signal strength value as the abscissa and the probability of the first historical signal strength value as the ordinate to obtain the probability distribution diagram of the first historical signal strength value. For example, the abscissa is the RSSI, and the ordinate is the probability of the RSSI.
步骤b:定位设备根据该第一历史信号强度值的概率分布图确定待拟定的概率分布模型,并计算该待拟合的概率分布模型的特征值。Step b: The positioning device determines the probability distribution model to be drawn according to the probability distribution map of the first historical signal strength value, and calculates the characteristic value of the probability distribution model to be fitted.
可选的,定位设备通过极大似然估计法计算该待拟定的概率分布模型的特征值。Optionally, the positioning device calculates the characteristic value of the probability distribution model to be drawn by using a maximum likelihood estimation method.
由实验数据可知,第一历史强度值的概率分布与韦尔布分布较为吻合,所以该待拟合的概率分布模型为韦尔布分布模型。It can be seen from the experimental data that the probability distribution of the first historical intensity value is more consistent with the Welbe distribution, so the probability distribution model to be fitted is the Welbe distribution model.
步骤c:定位设备将该特征值代入该待拟合的概率分布模型,得到该第一参考模型。Step c: The positioning device substitutes the characteristic value into the probability distribution model to be fitted to obtain the first reference model.
二、介绍定位设备拟合第二参考模型的过程。2. Introduce the process of positioning equipment fitting the second reference model.
该定位设备拟合第二参考模型的过程与定位设备拟合第一参考模型的过程类似。由实验数据可知,该第二历史信号强度值的概率分布与与高斯分布较为吻合,那么拟合得到的第二参考模型可以为高斯分布模型。The process of fitting the second reference model by the positioning device is similar to the process of fitting the first reference model by the positioning device. It can be known from the experimental data that the probability distribution of the second historical signal strength value is more consistent with the Gaussian distribution, and the second reference model obtained by fitting may be a Gaussian distribution model.
方式2:定位设备根据该P个第一信号强度值中的部分或全部第一信号强度值计算第一参考信号的多个信道状态参数,并根据该多个信道状态参数中的任一个或任多个信道状态参数确定该第一定位测量量对应的第一传播条件。Manner 2: The positioning device calculates multiple channel state parameters of the first reference signal according to some or all of the P first signal strength values, and calculates multiple channel state parameters of the first reference signal according to any one or any of the multiple channel state parameters A plurality of channel state parameters determine the first propagation condition corresponding to the first positioning measurement quantity.
基于方式2,步骤203包括步骤203b和步骤203c。Based on method 2, step 203 includes step 203b and step 203c.
步骤203b:定位设备根据该P个第一信号强度值中的部分或全部第一信号强度值计算第一参考信号的多个信道状态参数。Step 203b: The positioning device calculates multiple channel state parameters of the first reference signal according to some or all of the P first signal strength values.
该第一参考信号的多个信道状态参数包括该第一参考信号的标准差、峰值概率、偏度、峰度和H偏度。具体请参阅前述步骤201中对该第一参考信号的多个信道状态参数的计算方式的相关介绍,这里不再赘述。例如,如图2C所示,定位设备选择该P个第一信号强度值,然后计算该P个第一信号强度值的多个信道状态参数。The multiple channel state parameters of the first reference signal include the standard deviation, peak probability, skewness, kurtosis, and H skewness of the first reference signal. For details, please refer to the related introduction of the calculation method of the multiple channel state parameters of the first reference signal in the foregoing step 201, which will not be repeated here. For example, as shown in FIG. 2C, the positioning device selects the P first signal strength values, and then calculates multiple channel state parameters of the P first signal strength values.
当第一传播路径处于LOS状态下时,终端设备从接入网设备接收第一参考信号的第一信号强度值较大且较为稳定,即该P个第一信号强度值的大小相差较小。那么在该情况下,该第一参考信号的标准差较小,而峰值概率较大。而当第一传播路径处于NLOS状态时,由于第一参考信号是经过反射或散射后到达终端设备的,终端设备从接入网设备接收第一参考信号的第一信号强度值较小且易变,即该P个第一信号强度值的大小相差较大。那么在该情况下,该第一参考信号的标准差较大,峰值概率较小。因此,第一参考信号的标准差和峰值概率对表征该第一参考信号的传播条件的最具有代表性。When the first propagation path is in the LOS state, the first signal strength value of the first reference signal received by the terminal device from the access network device is relatively large and relatively stable, that is, the P first signal strength values have a small difference in magnitude. In this case, the standard deviation of the first reference signal is relatively small, and the peak probability is relatively large. When the first propagation path is in the NLOS state, since the first reference signal reaches the terminal device after reflection or scattering, the first signal strength value of the first reference signal received by the terminal device from the access network device is small and variable. , That is, the P first signal strength values have a large difference in magnitude. In this case, the standard deviation of the first reference signal is relatively large, and the peak probability is relatively small. Therefore, the standard deviation and peak probability of the first reference signal are the most representative of the propagation conditions of the first reference signal.

Wherein, when “0” is output, it indicates that the first propagation condition is that the first signal propagation path is in the NLOS state, and when “1” is output, it indicates that the first propagation condition is that the first signal propagation path is in the LOS state. Optionally, when “0” is output, it indicates that the first propagation condition is that the first signal propagation path is in LOS state; when “1” is output, it indicates that the first propagation condition is that the first signal propagation path is in NLOS state. state.
下面示出该定位设备根据该第一参考信号的标准差、峰值概率、偏度、峰度和H偏度确定该第一传播条件的具体过程,对于该定位设备仅通过该多个信号状态参数中的两个或三个或四个信号状态参数确定该第一传播条件类似,具体不再一一赘述。那么在该方式下,步骤203c具体包括步骤1至步骤5。The following shows the specific process of the positioning device determining the first propagation condition according to the standard deviation, peak probability, skewness, kurtosis, and H skewness of the first reference signal. For the positioning device, only the multiple signal state parameters are used. Two or three or four of the signal state parameters determine that the first propagation condition is similar, and the details are not repeated one by one. Then in this manner, step 203c specifically includes step 1 to step 5.
步骤1:定位设备按照预设的门限值对该第一参考信号的标准差、峰值概率、偏度、峰度和H偏度分别进行门限判决,得到第一门限判决结果。Step 1: The positioning device performs threshold judgment on the standard deviation, peak probability, skewness, kurtosis, and H skewness of the first reference signal according to the preset threshold value, and obtains the first threshold judgment result.
例如,如图2C所示,定位设备判断该第一参考信号的标准差是否大于第一预设门限值,若是,则y1=0;若否,则y1=1。定位设备判断该第一参考信号的峰值概率是否大于第二预设门限值,若是,则y2=1;若否,则y2=0。定位设备判断该第一参考信号的偏度是否大于第三预设门限值,若是,则y3=0;若否,则y4=1。定位设备判断该第一参考信号的峰值是否大于第四预设门限值,若是,则y4=1;若否,则y4=0。定位设备判断该第一参考信号的H偏度是否大于第五预设门限值,若是,则y5=0;若否,则y5=1。For example, as shown in FIG. 2C, the positioning device determines whether the standard deviation of the first reference signal is greater than the first preset threshold, if so, y1=0; if not, y1=1. The positioning device judges whether the peak probability of the first reference signal is greater than the second preset threshold value, if yes, then y2=1; if not, then y2=0. The positioning device judges whether the skewness of the first reference signal is greater than the third preset threshold, if so, y3=0; if not, y4=1. The positioning device judges whether the peak value of the first reference signal is greater than the fourth preset threshold, if so, y4=1; if not, y4=0. The positioning device judges whether the H skewness of the first reference signal is greater than the fifth preset threshold value, if yes, then y5=0; if not, then y5=1.
需要说明的是,本实施例中,第一预设门限值、第二预设门限值、第三预设门限值、第四预设门限值和第五预设门限值可以是经过历史测量得到的数据和多次试验确定的。It should be noted that in this embodiment, the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, and the fifth preset threshold may be It is determined by data obtained through historical measurement and many experiments.
步骤2:定位设备根据该第一门限判决结果进行加权计算,得到第一决策值。Step 2: The positioning device performs a weighted calculation according to the first threshold decision result to obtain the first decision value.
例如,如图2C所示,对y1至y5进行加权处理,具体可以将y1至y5分别乘以0.2,得到第一决策值。For example, as shown in FIG. 2C, to perform weighting processing on y1 to y5, specifically, y1 to y5 may be respectively multiplied by 0.2 to obtain the first decision value.
需要说明的是,上述加权计算,不同信道状态参数的权重可以相同,也可以不相同。例如,由于第一参考信号的标准差和峰值概率对表征该第一参考信号的传播条件的最具有代表性,那么该第一参考信号的标准差和峰值概率的权重可以较高。It should be noted that in the above weighting calculation, the weights of different channel state parameters may be the same or different. For example, since the standard deviation and peak probability of the first reference signal are the most representative for characterizing the propagation condition of the first reference signal, the weight of the standard deviation and peak probability of the first reference signal may be higher.
可选的,第一决策值还用于指示对第一参考信号的传播条件识别的可靠度。例如,通过第一决策值与第一预设决策值的接近程度来表征对第一参考信号的传播条件识别的可靠度,或者是通过第一决策值与第一传播路径的两种状态的代表值的接近程度表征对第一参考信号的传播条件识别的可靠度。例如,该第一传播路径处于LOS状态时,代表值为“1”;该第一传播路径为NLOS状态时,代表值为“0”。Optionally, the first decision value is also used to indicate the reliability of the identification of the propagation condition of the first reference signal. For example, the proximity of the first decision value to the first preset decision value is used to characterize the reliability of the recognition of the propagation condition of the first reference signal, or the first decision value and the representation of the two states of the first propagation path The closeness of the value characterizes the reliability of the recognition of the propagation condition of the first reference signal. For example, when the first propagation path is in the LOS state, the representative value is "1"; when the first propagation path is in the NLOS state, the representative value is "0".
步骤3:该定位设备判断该第一决策值是否大于第一预设决策值,若是,则执行步骤4;若否,则执行步骤4。Step 3: The positioning device judges whether the first decision value is greater than the first preset decision value, if yes, execute step 4; if not, execute step 4.
例如,该第一预设决策值为0.5,当第一决策值大于第一预设决策值时,执行步骤4;当该第一决策值小于或等于第一预设决策值时,执行步骤5。For example, the first preset decision value is 0.5, and when the first decision value is greater than the first preset decision value, step 4 is executed; when the first decision value is less than or equal to the first preset decision value, step 5 is executed .
需要说明的是,第一预设决策值可以是经过历史测量得到的数据和多次试验确定的。It should be noted that the first preset decision value may be determined by data obtained through historical measurement and multiple experiments.
步骤4:该定位设备确定第一传播条件为该第一信号传播路径处于LOS状态。Step 4: The positioning device determines that the first propagation condition is that the first signal propagation path is in the LOS state.
步骤5:该定位设备确定第一传播条件为该第一信号传播路径处于NLOS状态。Step 5: The positioning device determines that the first propagation condition is that the first signal propagation path is in the NLOS state.
由此可知,定位设备获取到第一定位测量量对应的P个第一信号强度值,并利用该P个第一信号强度值确定该第一传播条件。即定位设备利用该P个第一信号强度值获得有益于提高定位精度的更多信息。It can be seen from this that the positioning device obtains P first signal strength values corresponding to the first positioning measurement, and uses the P first signal strength values to determine the first propagation condition. That is, the positioning device uses the P first signal strength values to obtain more information that is beneficial to improving positioning accuracy.

在实际应用中,定位设备通常通过多站定位的方式定位终端设备的位置,该多站定位的方式指定位设备通过多个基站发送该定位参考信号用于确定该终端设备的位置。因此,通过本申请实施例提供的通信方法,多个终端设备上报的定位测量量都有对应的NLOS状态指示或LOS状态指示。而由于在下行传播路径处于NLOS状态下测量得到的定位测量量的准确性较低,那么定位设备在定位计算时可以排除下行传播路径处于NLOS状态下测量得到的定位测量量,即只挑选在下行信号传播路径处于LOS状态下测定得到的定位测量量作定位计算,从而提高定位精度。In practical applications, the positioning device usually locates the position of the terminal device by means of multi-station positioning. The multi-station positioning method specifies that the positioning device sends the positioning reference signal through multiple base stations to determine the position of the terminal device. Therefore, through the communication method provided by the embodiments of the present application, the positioning measurement quantities reported by multiple terminal devices have corresponding NLOS status indications or LOS status indications. However, because the accuracy of the positioning measurement measured when the downlink propagation path is in the NLOS state is low, the positioning device can exclude the positioning measurement measured when the downlink propagation path is in the NLOS state during the positioning calculation, that is, only select the positioning measurement when the downlink propagation path is in the NLOS state. The positioning measurement measured when the signal propagation path is in the LOS state is used for positioning calculation, thereby improving positioning accuracy.

For example, the first positioning measurement is measured when the first signal propagation path is in the NLOS state. Since the accuracy of the positioning measurement value measured when the first signal propagation path is in the NLOS state is low, the positioning device can exclude the first positioning measurement value during the positioning calculation, that is, only select when the first signal propagation path is in the The positioning measurement in the LOS state is used for positioning calculation, thereby improving positioning accuracy.
