下面对本申请实施例涉及的相关技术及术语进行说明。Relevant technologies and terminology involved in the embodiments of this application are described below.

一、时频资源1. Time-frequency resources

采用正交频分复用(orthogonal frequency division multiplexing，OFDM)技术的通信***中，将无线资源在频域上将载波带宽划分为了等间隔的多个子载波。子载波为频域资源的最小单位，时域符号为时域资源的最小单位，其中，时域符号可以称为OFDM符号。In a communication system using orthogonal frequency division multiplexing (OFDM) technology, wireless resources are divided into multiple equally spaced subcarriers in the frequency domain by dividing the carrier bandwidth. A subcarrier is the smallest unit of frequency domain resources, and a time domain symbol is the smallest unit of time domain resources. The time domain symbol can be called an OFDM symbol.

资源块(resource block，RB)：频域资源调度单位，在频域上载波带宽内每连续12个子载波组成一个RB，如图2所示，一个RB包括子载波0至子载波11共12个子载波。通信装置的载波带宽内包括一个或多个RB。Resource block (RB): Frequency domain resource scheduling unit. Every 12 consecutive subcarriers within the carrier bandwidth in the frequency domain form an RB. As shown in Figure 2, an RB includes subcarriers 0 to 11, a total of 12 subcarriers. carrier. One or more RBs are included within the carrier bandwidth of the communication device.

时隙：在时域上每连续14个时域符号组成一个时隙，如图2所示，一个时隙包括符号0至符号13共14个符号。Time slot: In the time domain, every 14 consecutive time domain symbols form a time slot. As shown in Figure 2, a time slot includes a total of 14 symbols from symbol 0 to symbol 13.

二、定位技术2. Positioning technology

在移动通信***中，网络可以通过获取多个接入网设备与终端设备之间的距离，基于多个接入网设备与终端设备之间的距离以及每个接入网设备的位置坐标可以计算得到终端设备的坐标。因此，定位精度主要受限于测距精度。目前主要的测距技术包括基于视距(line of sight，LOS)传输路径的信号到达时间的到达时间(time of arrival，TOA)测距技术、到达时间差(time difference of arrival，TDOA)测距技术和载波相位测距技术。In the mobile communication system, the network can obtain the distances between multiple access network devices and terminal devices, and calculate based on the distances between multiple access network devices and terminal devices and the location coordinates of each access network device. Get the coordinates of the terminal device. Therefore, positioning accuracy is mainly limited by ranging accuracy. The current main ranging technologies include time of arrival (TOA) ranging based on the signal arrival time of the line of sight (LOS) transmission path. technology, time difference of arrival (TDOA) ranging technology and carrier phase ranging technology.

三、TOA和TDOA3. TOA and TDOA

TOA技术是测量视线(line of sight，LOS)路径(或称为直射径)信号的到达时间与光速相乘后得到信号发送端与接收端之间的距离的测距技术。通过TOA测距可以得到多个接收端中每个接收端与发送端的距离，在基于多个接收端(发送端)的位置信息可以得到发送端(接收端)的的位置信息。TOA technology is a ranging technology that measures the arrival time of the line of sight (LOS) path (or direct path) signal multiplied by the speed of light to obtain the distance between the signal transmitter and the receiver. Through TOA ranging, the distance between each receiving end and the sending end among multiple receiving ends can be obtained. Based on the location information of multiple receiving ends (sending ends), the location information of the sending end (receiving end) can be obtained.

TDOA技术是对TOA技术的演进，基于测量信道到达多个接收端之间的时间差得到发送端与多个接收端之间的距离差，结合多个接收端的位置信息可以得到发送端的位置信息。通过TDOA技术可以消除发送端与接收端之间的时间同步偏差，即时钟误差对定位精度的影响。TDOA测距精度的克拉美罗下界(Cramer-Rao lower bound，CRLB)满足下式：
TDOA technology is an evolution of TOA technology. Based on measuring the time difference between the arrival of the channel and multiple receivers, the distance difference between the sender and multiple receivers is obtained. The location information of the sender can be obtained by combining the location information of multiple receivers. Through TDOA technology, the time synchronization deviation between the sending end and the receiving end can be eliminated, that is, the impact of clock error on positioning accuracy. The Cramer-Rao lower bound (CRLB) of TDOA ranging accuracy satisfies the following formula:

其中，var(d)为距离d的方差，c为光速，R_SNR为参考信号的信号与噪声的功率比，即信噪比(signal to noise ratio，SNR)，B为信号带宽。基于上式可知，TDOA测距精度与带宽相关，带宽越大能够测量得到的距离越精细，测量精度越高。然而，频谱资源有限，TDOA难以满足分米级及更高精度的定位需求。Among them, var(d) is the variance of distance d, c is the speed of light, R _SNR is the power ratio of the signal to noise of the reference signal, that is, the signal to noise ratio (SNR), and B is the signal bandwidth. Based on the above formula, it can be seen that the TDOA ranging accuracy is related to the bandwidth. The larger the bandwidth, the finer the distance that can be measured, and the higher the measurement accuracy. However, spectrum resources are limited, and TDOA is difficult to meet the positioning requirements of decimeter level and higher accuracy.

四、载波相位测距技术4. Carrier phase ranging technology

载波相位定位技术是目前高精度定位的主要方法之一，通过测量参考信号从发射端到接收端的载波相位变化实现测量带有整周模糊度的距离。例如，发送端301向接收端302发送参考信号，该参考信号的波形如图3所示，其中，为载波相位测量值，即参考信号到达接收端302时，接收端302测量到的信号的载波相位。N为整周模糊度，即发送端301与接收端302之间的距离包含的载波波长λ的整数倍数，发送端301与接收端302之间的距离d满足下式：
Carrier phase positioning technology is one of the main methods of high-precision positioning at present. By measuring the carrier phase change of the reference signal from the transmitting end to the receiving end, the distance with whole-circuit ambiguity can be measured. For example, the transmitting end 301 sends a reference signal to the receiving end 302. The waveform of the reference signal is as shown in Figure 3, where, is the carrier phase measurement value, that is, when the reference signal reaches the receiving end 302, the carrier phase of the signal measured by the receiving end 302. N is the integer ambiguity, that is, the integer multiple of the carrier wavelength λ contained in the distance between the sending end 301 and the receiving end 302. The distance d between the sending end 301 and the receiving end 302 satisfies the following formula:

接收端302可以向发送端301反馈载波相位测量值由发送端301基于载波相位测量值计算距离d。或者，接收端302可以向发送端301反馈计算得到的距离d。基于上述载波相位测距技术，可以通过多个发送端向接收端发送参考信号，并获取多个发送端与该接收端之间的距离，再基于多个发送端的位置信息，可以确定接收端的位置坐标，实现对接收端的定位。The receiving end 302 can feed back the carrier phase measurement value to the transmitting end 301, and the transmitting end 301 calculates the distance d based on the carrier phase measurement value. Alternatively, the receiving end 302 may feed back the calculated distance d to the sending end 301. Based on the above carrier phase ranging technology, reference signals can be sent to the receiving end through multiple transmitting ends, and the distances between multiple transmitting ends and the receiving end can be obtained. Based on the location information of multiple transmitting ends, the location of the receiving end can be determined. coordinates to achieve positioning of the receiving end.

载波相位测距精度的克拉美罗下界(Cramer-Rao lower bound，CRLB)满足下式：
The Cramer-Rao lower bound (CRLB) of the carrier phase ranging accuracy satisfies the following formula:

其中，f为载波频率，M为载波相位的测量次数。基于上式可知，信噪比R_SNR、载波频率f、以及载波相位的测量次数M越大，能够测量得到的距离越精细，即测量精度越高。而信噪比取决于信道环境，载波频率由发送参考信号的通信设备的实现决定，本申请提出可以通过设计参考信号承载在时域连续的资源上，以提高载波相位的测量次数，从而达到提高测距精度的效果。Among them, f is the carrier frequency, and M is the number of measurements of the carrier phase. Based on the above equation, it can be seen that the greater the number of measurements M of the signal-to-noise ratio _RSNR , carrier frequency f, and carrier phase, the finer the distance that can be measured, that is, the higher the measurement accuracy. The signal-to-noise ratio depends on the channel environment, and the carrier frequency is determined by the implementation of the communication equipment that sends the reference signal. This application proposes that the reference signal can be designed to be carried on a continuous resource in the time domain to increase the number of carrier phase measurements, thereby improving The effect of ranging accuracy.

The N first REs included in the reference signal resources are located on the same subcarrier (i.e., the first subcarrier) in the frequency domain and are in the time domain. continuous, that is, they are located in consecutive N time domain symbols. For example, as shown in Figure 5, the reference signal resource includes 14 first REs of subcarrier 7 (i.e., an example of the first subcarrier) located in one RB in the frequency domain, that is, N=14. In the time domain, the 14 The REs are respectively located in 14 consecutive time domain symbols, and the 14 time domain symbols can be located in one time slot.

The REs located at symbol 0 in the time domain are all second REs, where the M second REs in the reference signal resource include one of the 14 first REs, that is, located at symbol 0 in the time domain. And the frequency domain is located at the RE of subcarrier 6 in RB _k , that is to say, this RE is both the first RE and the second RE. The position of the second RE in other RBs among the K RBs occupied by the reference signal resource (that is, the RBs not shown in Figure 6) is the same as RB _k+1 , and can be implemented with reference to RB _k+1 , which will not be described again here. .

As shown in FIG. 6 , the M second REs in the reference signal resource are located at symbol 0 in the time domain, and the identification information of the time domain symbol indicated by the third indication information is 0.

例如，M个第二RE占用的符号个数为2，相邻第二RE的频域间隔为2，则第一个符号上的第一个第二RE占用子载波0，第二个符号上的第一个第二RE占用子载波1，或者说第二个符号上第二RE的comb结构相较于第一个符号上第二RE的comb结构频域偏移一个子载波，如图9所示。M个第二RE占用的符号个数为2，相邻第二RE的频域间隔为4，则第一个符号上的第一个第二RE占用子载波0，第二个符号上的第一个第二RE占用子载波2，或者说第二个符号上第二RE的comb结构相较于第一个符号上第二RE的comb结构频域偏移两个子载波，如图11所示。For example, the number of symbols occupied by M second REs is 2, and the frequency domain interval between adjacent second REs is 2, then the first second RE on the first symbol occupies subcarrier 0, and the second RE on the second symbol occupies subcarrier 0. The first second RE occupies subcarrier 1, or the comb structure of the second RE on the second symbol is shifted by one subcarrier in the frequency domain compared to the comb structure of the second RE on the first symbol, as shown in Figure 9 shown. The number of symbols occupied by the M second REs is 2, and the frequency domain interval between adjacent second REs is 4.

另一个示例中，该第一配置信息还包括用于指示每个时域符号上第一个第二RE的频域位置的指示信息。In another example, the first configuration information further includes indication information indicating the frequency domain position of the first second RE on each time domain symbol.

例如，参考信号资源占用一个时隙中的前4个时域符号，该第一配置信息指示4个时域符号中每个时域符号上第一个第二RE占用的子载波依次分别为0、2、1、3，接收该第一配置信息的通信装置可以基于第一配置信息确定M个第二RE的时频位置如图10所示。For example, the reference signal resource occupies the first 4 time domain symbols in a time slot, and the first configuration information indicates that the subcarriers occupied by the first and second RE on each of the 4 time domain symbols are sequentially 0. , 2, 1, and 3. The communication device that receives the first configuration information can determine the time-frequency positions of the M second REs based on the first configuration information, as shown in Figure 10.

再例如，若M个第二RE占用的符号个数大于1，第一配置信息还可以包括梳状结构频移(comb offset)指示信息，该指示信息用于指示相邻两个符号的第二RE的梳状结构之间偏移的RE个数。以图9为例，第一配置信息指示M个第二RE占用的符号个数为2，则通信装置可以确定M个第二RE位于参考信号资源所在的时隙中的前两个符号，即符号0和符号1，该第一配置信息中的第二指示信息指示该参考信号资源中位于同一时域符号且在频域上相邻的两个第二RE之间的频域间隔为2个RE，通信装置基于第二指示信息可以确定符号0上每个RB的子载波0、2、4、6、8、10为第二RE。第一配置信息还包括梳状结构偏移指示信息，该指示信息指示相邻两个符号的第二RE的梳状结构之间偏移的RE个数为1，则通信装置可以确定符号1上的第二RE的梳状结构相较于符号0上的第二RE的梳状结构频移一个RE，则通信装置可以确定符号1上每个RB的子载波1、3、5、7、9、11为第二RE。For another example, if the number of symbols occupied by M second REs is greater than 1, the first configuration information may also include comb structure frequency shift (comb offset) indication information, which is used to indicate the second frequency of two adjacent symbols. The number of offset REs between RE comb structures. Taking Figure 9 as an example, the first configuration information indicates that the number of symbols occupied by the M second REs is 2, then the communication device can determine that the M second REs are located in the first two symbols of the time slot where the reference signal resource is located, that is, Symbol 0 and symbol 1, the second indication information in the first configuration information indicates that the frequency domain interval between two second REs located in the same time domain symbol and adjacent in the frequency domain in the reference signal resource is 2 RE, the communication device may determine that subcarriers 0, 2, 4, 6, 8, and 10 of each RB on symbol 0 are the second RE based on the second indication information. The first configuration information also includes comb structure offset indication information. The indication information indicates that the number of offset REs between the comb structures of the second REs of two adjacent symbols is 1. Then the communication device can determine that the number of offset REs on symbol 1 is 1. The comb structure of the second RE is frequency shifted by one RE compared to the comb structure of the second RE on symbol 0, then the communication device can determine subcarriers 1, 3, 5, 7, and 9 of each RB on symbol 1 , 11 is the second RE.
