- the delay and Doppler characteristics of the channel are essentially determined by the multipath channel. Signals arriving at the receiver through different paths have different arrival times due to differences in propagation distances. For example, if two echoes s 1 and s 2 arrive at the receiver via distances d 1 and d 2 respectively, then the time difference between them arriving at the receiver is c is the speed of light. Due to this time difference between echoes s 1 and s 2 , their incoherent superposition at the receiver side causes the observed signal amplitude jitter, a fading effect. Similarly, Doppler dispersion in multipath channels is also caused by the multipath effect.
- the Doppler effect is due to the relative speed of the two ends of the transmitter and the receiver.
- the signals arriving at the receiver after different paths have different incident angles relative to the normal line of the antenna, which results in differences in relative speeds, which in turn causes multiple signals on different paths.
- the Puller shift is different. Assume that the original frequency of the signal is f 0 , the relative velocity of the transmitter and receiver is ⁇ v, and the normal incidence angle between the signal and the receiver antenna is ⁇ . Then there are: Obviously, when the two echoes s 1 and s 2 arrive at the receiving end antenna through different paths and have different incident angles ⁇ 1 and ⁇ 2 , the resulting Doppler frequency shifts ⁇ f 1 and ⁇ f 2 are also different.
- the signal seen by the receiver is the superposition of component signals with different delays and Dopplers from different paths, and the overall reflection is a received signal with fading and frequency shift relative to the original signal.
- Delay Doppler analysis of the channel helps to collect delay Doppler information of each path, thereby reflecting the delay Doppler response of the channel.
- OTFS modulation technology is orthogonal time-frequency spatial modulation.
- This technology puts a data packet of size M ⁇ N into Information, such as Quadrature Amplitude Modulation (QAM) symbols, is logically mapped to an M ⁇ N grid point on the two-dimensional delay Doppler plane, that is, the pulse in each grid point modulates the data A QAM symbol in the packet.
- QAM Quadrature Amplitude Modulation
- the data set on the M ⁇ N delayed Doppler domain plane can be transformed into the N ⁇ M time-frequency domain plane by designing a set of orthogonal two-dimensional basis functions.
- This transformation is mathematically called Inverse Sympletic Fourier Transform (ISSFT).
- the transformation from the time-frequency domain to the delayed Doppler domain is called the Sympletic Fourier Transform (SFFT).
- SFFT Sympletic Fourier Transform
- the physical meaning behind it is that the signal delay and Doppler effect are actually a linear superposition effect of a series of echoes with different time and frequency offsets after the signal passes through multiple channels. That is, delayed Doppler analysis and time-frequency domain analysis can be obtained by mutual conversion of the ISSFT and SSFT.
- Figure 2 is a schematic diagram of the mutual conversion between the delay Doppler plane and the time-frequency plane provided by the embodiment of the present application; as shown in Figure 2, the OTFS technology can transform the time-varying multipath channel into a time-varying channel (within a certain duration)
- the invariant two-dimensional delay Doppler domain channel directly reflects the channel delay Doppler response characteristics caused by the geometric characteristics of the relative position of the reflectors between the transceivers in the wireless link.
- the advantage of this is that OTFS eliminates the difficulty of tracking time-varying fading characteristics with traditional time-frequency domain analysis, and instead extracts all diversity characteristics of time-frequency domain channels through delayed Doppler domain analysis.
- the channel impulse response matrix represented by the delay Doppler domain is sparse.
- the core of OTFS modulation is symbols defined on the delayed Doppler plane, which are transformed into the time-frequency domain for transmission, and then returned to the delayed Doppler domain for processing at the receiving end. Therefore, the wireless channel response analysis method in the delayed Doppler domain can be introduced.
- Figure 3 is a schematic diagram of the channel response relationship in different planes provided by the embodiment of the present application. As shown in Figure 3, it reflects the relationship between the expression of the channel response in different planes when the signal passes through the linear time-varying wireless channel;
- h( ⁇ ,v) represents the delayed Doppler domain channel
- H(t,f) represents the time-frequency domain channel
- g(t, ⁇ ) represents the time delay domain channel
- B(v,f) represents Frequency Doppler domain channel
- t, f, ⁇ , v represent time, frequency, delay and Doppler respectively.
- H(t,f) the transformation formula of ISSFT.
- H(t,f) ⁇ h( ⁇ , ⁇ )e j2 ⁇ ( ⁇ t-f ⁇ ) d ⁇ d ⁇ ;
- the delayed Doppler domain channel h( ⁇ ,v) is the sum of all multipath channels and can be expressed as:
- P represents the total number of paths
- h i represents the channel gain of the i-th path
- ⁇ () represents the Dirac delta function
- ⁇ i represents the delay of the i-th path
- vi represents the Doppler of the i-th path.
- Equation (7) it can be seen that the analysis of the delayed Doppler domain in the OTFS system can be achieved by relying on the existing communication framework established in the time-frequency domain and adding additional signal processing processes at the transceiver end. Moreover, the additional signal processing only consists of Fourier transform and can be completely implemented by existing hardware without the need for new modules. This good compatibility with existing hardware systems greatly facilitates the application of OTFS systems.
- OTFS technology can be easily implemented as the pre- and post-processing modules of a filtered Orthogonal Frequency Division Multiplexing (OFDM) system, so it is compatible with the existing New Radio , NR) multi-carrier system under the technical architecture has good compatibility.
- OFDM Orthogonal Frequency Division Multiplexing
- the transmitter When OTFS is combined with a multi-carrier system, the transmitter is implemented as follows: the QAM symbols containing the information to be sent are carried by the waveform of the delayed Doppler plane, and undergo a two-dimensional inverse sympletic Finite Fourier Transform (ISFFT) ), is converted into a time-frequency domain plane waveform in a traditional multi-carrier system, and then undergoes symbol-level one-dimensional inverse fast Fourier Transform (IFFT) and serial-to-parallel conversion to become a time domain sampling point for transmission go out.
- ISFFT inverse sympletic Finite Fourier Transform
- FIG 4 is a schematic diagram of the processing flow of the transceiver end of the OTFS multi-carrier system provided by the embodiment of the present application.
- the receiving end of the OTFS system is roughly the reverse process of the transmitting end: after the time domain sampling point is received by the receiver, Parallel conversion and symbol-level one-dimensional Fast Fourier Transform (FFT) are first transformed into waveforms on the time-frequency domain plane, and then undergo two-dimensional Sympletic Finite Fourier Transform (SFFT) , converted into a delayed Doppler domain plane waveform, and then the QAM symbols carried by the delayed Doppler domain waveform are processed by the receiver: including channel estimation and equalization, demodulation and decoding, etc.
- FFT Fast Fourier Transform
- SFFT Sympletic Finite Fourier Transform
- OTFS modulation converts the time-varying fading channel in the time-frequency domain between transceivers into a deterministic fading-free channel in the delayed Doppler domain.
- each symbol in a set of information symbols sent at a time experiences the same static channel response and signal-to-noise ratio (SNR).
- SNR signal-to-noise ratio
- the OTFS system analyzes the reflectors in the physical channel through delayed Doppler images and uses the receiving equalizer Coherently combining energy from different reflection paths effectively provides a static channel response without fading. Utilizing the above static channel characteristics, OTFS systems do not need to introduce closed-loop channel adaptation like OFDM systems to cope with rapidly changing channels, thus improving system robustness and reducing system design complexity.
- the channel in the OTFS system can be expressed in a very compact form.
- the channel estimation overhead of the OTFS system is less and more accurate.
- Figure 5 is a schematic diagram of pilot mapping in the delayed Doppler domain provided by an embodiment of the present application; as shown in Figure 5, pulse pilots can be used for channel estimation in the OTFS system.
- the transmitter places a pilot in the delayed Doppler domain, converts it to the time-frequency domain and then sends it out.
- the receiver undergoes corresponding inverse operations to obtain the grid pattern of the delayed Doppler domain. Due to the effect of the channel, several offset pilot copies will appear in the guard symbols of the delayed Doppler domain grid points (the resource grid where the squares in the delayed Doppler resource grid on the right side of Figure 5 are located), which means that the channel Several paths with different delayed Dopplers may occur.
- the channel response h( ⁇ , ⁇ ) in the delayed Doppler domain can be estimated, and then the channel response expression in the time-frequency domain can be obtained to facilitate signal analysis and processing.

用于描述信号质量的信息可以用于功率控制、小区切换等通信流程,以保证终端的通信质量;Information used to describe signal quality can be used in communication processes such as power control and cell switching to ensure the communication quality of the terminal;
但目前缺乏基于延迟多普勒域的信号的质量信息定义方法,若同步信号、参考信号、或用于测量交叉链路干扰(Cross Link Interference,CLI)的信号等映射在延迟多普勒域,则终端无法进行小区切换和功率控制,进而导致终端的通信质量下降。However, there is currently a lack of quality information definition method for signals based on the delayed Doppler domain.

首先对以下内容进行介绍:First, the following content is introduced:
1、正交时频空域(Orthogonal Time Frequency Space,OTFS)通信技术;1. Orthogonal Time Frequency Space (OTFS) communication technology;
信道的延迟和多普勒的特性本质上由多径信道决定。通过不同路径到达接收机的信号,因为传播路程存在差异,因此到达时间也不同。例如两个回波s1和s2各自经历距离d1和d2到达接收机,则他们抵达接收机的时间差为c为光速。由于回波s1和s2之间存在这种时间差,它们在接收机侧的非相干叠加造成了观测到的信号幅度抖动,即衰落效应。类似的,多径信道的多普勒扩散也是由于多径效应造成。The delay and Doppler characteristics of the channel are essentially determined by the multipath channel. Signals arriving at the receiver through different paths have different arrival times due to differences in propagation distances. For example, if two echoes s 1 and s 2 arrive at the receiver via distances d 1 and d 2 respectively, then the time difference between them arriving at the receiver is c is the speed of light. Due to this time difference between echoes s 1 and s 2 , their incoherent superposition at the receiver side causes the observed signal amplitude jitter, a fading effect. Similarly, Doppler dispersion in multipath channels is also caused by the multipath effect.
多普勒效应是由于收发两端存在相对速度,历经不同路径到达接收机的信号,其相对于天线法线的入射角度存在差异,因此造成了相对速度的差异,进而造成了不同路径信号的多普勒频移不同。假设信号的原始频率为f0,收发端的相对速度为Δv,信号与接收端天线的法线入射夹角为θ。则有:显然,当两个回波s1和s2历经不同路径到达接收端天线而具有不同的入射角θ1和θ2时,所得到的多普勒频移Δf1和Δf2也不同。The Doppler effect is due to the relative speed of the two ends of the transmitter and the receiver. The signals arriving at the receiver after different paths have different incident angles relative to the normal line of the antenna, which results in differences in relative speeds, which in turn causes multiple signals on different paths. The Puller shift is different. Assume that the original frequency of the signal is f 0 , the relative velocity of the transmitter and receiver is Δv, and the normal incidence angle between the signal and the receiver antenna is θ. Then there are: Obviously, when the two echoes s 1 and s 2 arrive at the receiving end antenna through different paths and have different incident angles θ 1 and θ 2 , the resulting Doppler frequency shifts Δf 1 and Δf 2 are also different.
综上所述,接收机端看到的信号是来自不同路径的具有不同时延和多普勒的分量信号的叠加,整体体现为一个相对原信号具有衰落和频移的接收信号。而对信道进行延迟多普勒分析,则有助于收集每个路径的延迟多普勒信息,从而反映信道的延迟多普勒响应。To sum up, the signal seen by the receiver is the superposition of component signals with different delays and Dopplers from different paths, and the overall reflection is a received signal with fading and frequency shift relative to the original signal. Delay Doppler analysis of the channel helps to collect delay Doppler information of each path, thereby reflecting the delay Doppler response of the channel.
OTFS调制技术的全称是正交时频空域调制。该技术把一个大小为M×N的数据包中
的信息,例如正交振幅调制(Quadrature Amplitude Modulation,QAM)符号,在逻辑上映射到二维延迟多普勒平面上的一个M×N格点中,即每个格点内的脉冲调制了数据包中的一个QAM符号。The full name of OTFS modulation technology is orthogonal time-frequency spatial modulation. This technology puts a data packet of size M×N into Information, such as Quadrature Amplitude Modulation (QAM) symbols, is logically mapped to an M×N grid point on the two-dimensional delay Doppler plane, that is, the pulse in each grid point modulates the data A QAM symbol in the packet.
进一步的,可以通过设计一组正交二维基函数,将M×N的延迟多普勒域平面上的数据集变换到N×M的时频域平面上,这种变换在数学上被称为逆辛傅里叶变换(Inverse Sympletic Fourier Transform,ISSFT)。Furthermore, the data set on the M×N delayed Doppler domain plane can be transformed into the N×M time-frequency domain plane by designing a set of orthogonal two-dimensional basis functions. This transformation is mathematically called Inverse Sympletic Fourier Transform (ISSFT).
对应的,从时频域到延迟多普勒域的变换被称为辛傅里叶变换(Sympletic Fourier Transform,SFFT)。其背后的物理意义是,信号的延迟和多普勒效应,实际上是一种信号通过多经信道后的一系列具有不同时间和频率偏移的回波的线性叠加效应。即,延迟多普勒分析和时频域分析可以通过所述的ISSFT和SSFT相互转换得到。Correspondingly, the transformation from the time-frequency domain to the delayed Doppler domain is called the Sympletic Fourier Transform (SFFT). The physical meaning behind it is that the signal delay and Doppler effect are actually a linear superposition effect of a series of echoes with different time and frequency offsets after the signal passes through multiple channels. That is, delayed Doppler analysis and time-frequency domain analysis can be obtained by mutual conversion of the ISSFT and SSFT.
图2是本申请实施例提供的延迟多普勒平面和时间频率平面的相互转换的示意图;如图2所示,OTFS技术可以把时变多径信道变换为一个(一定持续时间内的)时不变二维延迟多普勒域信道,从而直接体现了无线链路中由于收发机之间的反射体相对位置的几何特性造成的信道延迟多普勒响应特性。这样的好处是:OTFS消除了传统时频域分析跟踪时变衰落特性的难点,转而通过延迟多普勒域分析抽取出时频域信道的所有分集特性。实际***中,由于信道的延迟径和多普勒频移的数量远远小于信道的时域和频域响应数量,用延迟多普勒域表征的信道冲激响应矩阵具有稀疏性。利用OTFS技术在延迟多普勒域对稀疏信道矩阵进行分析,可以使参考信号的封装更加紧密和灵活。Figure 2 is a schematic diagram of the mutual conversion between the delay Doppler plane and the time-frequency plane provided by the embodiment of the present application; as shown in Figure 2, the OTFS technology can transform the time-varying multipath channel into a time-varying channel (within a certain duration) The invariant two-dimensional delay Doppler domain channel directly reflects the channel delay Doppler response characteristics caused by the geometric characteristics of the relative position of the reflectors between the transceivers in the wireless link. The advantage of this is that OTFS eliminates the difficulty of tracking time-varying fading characteristics with traditional time-frequency domain analysis, and instead extracts all diversity characteristics of time-frequency domain channels through delayed Doppler domain analysis. In actual systems, since the number of delay paths and Doppler frequency shifts of the channel is far smaller than the number of time domain and frequency domain responses of the channel, the channel impulse response matrix represented by the delay Doppler domain is sparse. Using OTFS technology to analyze the sparse channel matrix in the delayed Doppler domain can make the reference signal packaging more compact and flexible.
OTFS调制的核心是定义在延迟多普勒平面上的符号,变换到时频域进行发送,然后收端回到延迟多普勒域处理。因而可以引入延迟多普勒域上的无线信道响应分析方法。The core of OTFS modulation is symbols defined on the delayed Doppler plane, which are transformed into the time-frequency domain for transmission, and then returned to the delayed Doppler domain for processing at the receiving end. Therefore, the wireless channel response analysis method in the delayed Doppler domain can be introduced.

r(t)=s(t)*h(t)=∫g(t,τ)s(t-τ)dτ; (4)
r(t)=s(t)*h(t)=∫g(t,τ)s(t-τ)dτ; (4)When the signal passes through a linear time-varying channel, let the time domain received signal be r(t), and its corresponding frequency domain received signal is R(f), and there is r(t) can be expressed as follows:

From the relationship shown in Figure 3, the classical Fourier transform theory, and formula (6), we can know:
基于等式(7)可知,在OTFS***进行延迟多普勒域的分析,可以依托现有的建立在时频域上的通信框架,在收发端加上额外的信号处理过程来实现。并且,所述额外的信号处理仅由傅里叶变换组成,可以完全通过现有的硬件实现,无需新增模块。这种与现有硬件体系的良好兼容性大大方便了OTFS***的应用。Based on Equation (7), it can be seen that the analysis of the delayed Doppler domain in the OTFS system can be achieved by relying on the existing communication framework established in the time-frequency domain and adding additional signal processing processes at the transceiver end. Moreover, the additional signal processing only consists of Fourier transform and can be completely implemented by existing hardware without the need for new modules. This good compatibility with existing hardware systems greatly facilitates the application of OTFS systems.
实际***中,OTFS技术可以很方便的被实现为一个滤波正交频分复用技术(Orthogonal Frequency Division Multiplexing,OFDM)***的前置和后置处理模块,因此与现有的新空口(New Radio,NR)技术架构下的多载波***有着很好的兼容性。In actual systems, OTFS technology can be easily implemented as the pre- and post-processing modules of a filtered Orthogonal Frequency Division Multiplexing (OFDM) system, so it is compatible with the existing New Radio , NR) multi-carrier system under the technical architecture has good compatibility.
OTFS与多载波***结合时,发送端的实现方式如下:含有需要发送信息的QAM符号由延迟多普勒平面的波形承载,经过一个二维的逆辛傅里叶变换(Inverse Sympletic Finite Fourier Transform,ISFFT),转换为传统多载波***中的时频域平面的波形,再经过符号级的一维逆快速傅里叶变换(Inverse Fast Fourier Transform,IFFT)和串并转换,变成时域采样点发送出去。When OTFS is combined with a multi-carrier system, the transmitter is implemented as follows: the QAM symbols containing the information to be sent are carried by the waveform of the delayed Doppler plane, and undergo a two-dimensional inverse sympletic Finite Fourier Transform (ISFFT) ), is converted into a time-frequency domain plane waveform in a traditional multi-carrier system, and then undergoes symbol-level one-dimensional inverse fast Fourier Transform (IFFT) and serial-to-parallel conversion to become a time domain sampling point for transmission go out.
图4是本申请实施例提供的OTFS多载波***的收发端处理流程示意图,如图4所示,OTFS***的接收端大致是一个发送端的逆过程:时域采样点经接收机接收后,经过并传转换和符号级的一维快速傅里叶变换(Fast Fourier Transform,FFT),先变换到时频域平面上的波形,然后经过二维辛傅里叶变换(Sympletic Finite Fourier Transform,SFFT),转换为延迟多普勒域平面的波形,然后对由延迟多普勒域波形承载的QAM符号进行接收机的处理:包括信道估计和均衡,解调和译码等。Figure 4 is a schematic diagram of the processing flow of the transceiver end of the OTFS multi-carrier system provided by the embodiment of the present application. As shown in Figure 4, the receiving end of the OTFS system is roughly the reverse process of the transmitting end: after the time domain sampling point is received by the receiver, Parallel conversion and symbol-level one-dimensional Fast Fourier Transform (FFT) are first transformed into waveforms on the time-frequency domain plane, and then undergo two-dimensional Sympletic Finite Fourier Transform (SFFT) , converted into a delayed Doppler domain plane waveform, and then the QAM symbols carried by the delayed Doppler domain waveform are processed by the receiver: including channel estimation and equalization, demodulation and decoding, etc.
OTFS调制的优越性主要体现在以下方面:The advantages of OTFS modulation are mainly reflected in the following aspects:
(a)OTFS调制把收发机之间的时频域中的时变衰落信道转化为延迟多普勒域中的确定性的无衰落信道。在延迟多普勒域中,一次发送的一组信息符号中的每个符号都经历相同的静态信道响应和信噪比(Signal Noise Ratio,SNR)。(a) OTFS modulation converts the time-varying fading channel in the time-frequency domain between transceivers into a deterministic fading-free channel in the delayed Doppler domain. In the delayed Doppler domain, each symbol in a set of information symbols sent at a time experiences the same static channel response and signal-to-noise ratio (SNR).
(b)OTFS***通过延迟多普勒图像解析出物理信道中的反射体,并用接收均衡器
对来自不同反射路径的能量进行相干合并,实际上提供了一个无衰落的静态信道响应。利用上述静态信道特性,OTFS***无需像OFDM***一样引入闭环信道自适应来应对快变的信道,因而提升了***健壮性并降低了***设计的复杂度。(b) The OTFS system analyzes the reflectors in the physical channel through delayed Doppler images and uses the receiving equalizer Coherently combining energy from different reflection paths effectively provides a static channel response without fading. Utilizing the above static channel characteristics, OTFS systems do not need to introduce closed-loop channel adaptation like OFDM systems to cope with rapidly changing channels, thus improving system robustness and reducing system design complexity.
(c)由于延迟多普勒域中的延迟-多普勒的状态数量远小于时频域的时间-频率状态数量,因而OTFS***中的信道可以表达为非常紧凑的形式。OTFS***的信道估计开销更少,更加精确。(c) Since the number of delay-Doppler states in the delay Doppler domain is much smaller than the number of time-frequency states in the time-frequency domain, the channel in the OTFS system can be expressed in a very compact form. The channel estimation overhead of the OTFS system is less and more accurate.
(d)OTFS的另一个优越性体现应对极致多普勒信道上。可以通过适当信号处理参数下对延迟多普勒图像的分析,信道的多普勒特性会被完整呈现,因而有利于多普勒敏感场景(例如高速移动和毫米波)下的信号分析和处理。(d) Another advantage of OTFS is in dealing with extreme Doppler channels. Through the analysis of delayed Doppler images under appropriate signal processing parameters, the Doppler characteristics of the channel will be fully presented, which is beneficial to signal analysis and processing in Doppler-sensitive scenarios (such as high-speed movement and millimeter waves).
图5是本申请实施例提供的延迟多普勒域的导频映射示意图;如图5所示,在OTFS***中可以采用脉冲导频进行信道估计。发射机在延迟多普勒域上放置导频,转换到时频域后发出。在维度为M×N的延迟多普勒域发送信号中放置脉冲导频(如图5左边延迟多普勒资源格中的方块所在的资源格),导频位置一般为(lp,kp);考虑信道的最大延迟和多普勒扩展,为了防止导频和数据间产生相互干扰从而导致信道估计的不准确,导频周围至少放置面积为(2lτ+1)(4kν+1)-1的保护符号(如图5左边延迟多普勒资源格中的圆圈所在的资源格),其中lτ=τmaxMΔf,kν=νmaxNT,τmax和νmax分别代表信道的最大延迟和最大多普勒频移;其余位置放置MN-(2lτ+1)(4kν+1)的数据(如图5左边延迟多普勒资源格中的叉号所在的资源格)。Figure 5 is a schematic diagram of pilot mapping in the delayed Doppler domain provided by an embodiment of the present application; as shown in Figure 5, pulse pilots can be used for channel estimation in the OTFS system. The transmitter places a pilot in the delayed Doppler domain, converts it to the time-frequency domain and then sends it out. Pulse pilots are placed in the delayed Doppler domain transmission signal with dimensions M ); Considering the maximum delay and Doppler spread of the channel, in order to prevent mutual interference between the pilot and the data, resulting in inaccurate channel estimation, at least the area surrounding the pilot is (2l τ +1) (4k ν +1) -1 protection symbol (the resource grid where the circle in the delay Doppler resource grid on the left side of Figure 5 is located), where l τ =τ max MΔf, k ν =ν max NT, τ max and ν max respectively represent the maximum channel Delay and maximum Doppler frequency shift; the data of MN-(2l τ +1)(4k ν +1) is placed in the remaining positions (the resource grid where the cross in the delay Doppler resource grid on the left side of Figure 5 is located).
如图5所示,接收机经过相应的逆操作,得到延迟多普勒域的网格图案。由于信道的作用,延迟多普勒域格点的保护符号中会出现若干个偏移后的导频副本(如图5右边延迟多普勒资源格中的方块所在的资源格),意味着信道可能会出现若干个具有不同延迟多普勒的路径。通过导频符号在接收端的位置偏移,估计出延迟多普勒域的信道响应h(τ,ν),进而可以得到时频域的信道响应表达式,方便进行信号分析和处理。As shown in Figure 5, the receiver undergoes corresponding inverse operations to obtain the grid pattern of the delayed Doppler domain. Due to the effect of the channel, several offset pilot copies will appear in the guard symbols of the delayed Doppler domain grid points (the resource grid where the squares in the delayed Doppler resource grid on the right side of Figure 5 are located), which means that the channel Several paths with different delayed Dopplers may occur. Through the position offset of the pilot symbol at the receiving end, the channel response h(τ,ν) in the delayed Doppler domain can be estimated, and then the channel response expression in the time-frequency domain can be obtained to facilitate signal analysis and processing.

在一个实施例中,以P个端口通过相互不重叠的延迟多普勒资源进行区分为例,第二RSRP计算方式可以为:In one embodiment, taking P ports that are distinguished by mutually non-overlapping delay Doppler resources as an example, the second RSRP calculation method can be:
P个端口通过相互不重叠的延迟多普勒资源进行区分时,在收端的延迟多普勒帧上需要制定P个第一延迟多普勒区域,对应P个端口。图8是本申请实施例提供的两端口时的第一延迟多普勒区域的示意图;如图8所示,描述了一个M=18,N=12,P=2的***,带斜杠的栅格区域为与第1个端口对应的第一延迟多普勒区域(图8中即延迟方向3到8、多普勒方向4到9的矩形区域),带棱型网格的栅格区域为与第2个端口对应的第一延迟多普勒区域(图8中即延迟方向11到16、多普勒方向4到9的矩形区域)。计算出每一个第一端口对应的第一RSRP;进而可以计算这P个第一RSRP的均值,记作第二RSRP。所述均值可以是线性均值,也可以是加权均值。或者计算这P个第一RSRP的最大值,记作第二RSRP。或者计算这P个第一RSRP的最小值,记作第二RSRP。When P ports are distinguished by mutually non-overlapping delay Doppler resources, P first delay Doppler areas need to be formulated on the delay Doppler frame at the receiving end, corresponding to P ports. Figure 8 is a schematic diagram of the first delayed Doppler area at two ports provided by the embodiment of the present application; as shown in Figure 8, a system with M=18, N=12, and P=2 is described, with slashes The grid area is the first delayed Doppler area corresponding to the first port (in Figure 8, the rectangular area with delay directions 3 to 8 and Doppler directions 4 to 9), a grid area with a prismatic grid is the first delayed Doppler area corresponding to the second port (in Figure 8, it is the rectangular area with delay directions 11 to 16 and Doppler directions 4 to 9). The first RSRP corresponding to each first port is calculated; then the average of the P first RSRPs can be calculated, which is recorded as the second RSRP. The mean can be a linear mean or a weighted mean. Or calculate the maximum value of the P first RSRPs and record it as the second RSRP. Or calculate the minimum value of the P first RSRPs and record it as the second RSRP.
在一个实施例中,第一RSSI的计算方式可以为:In one embodiment, the calculation method of the first RSSI may be:
计算第二延迟多普勒区域内所有格点上的接收信号的功率总和,再将该功率总和除以系数t(第三系数),记作第一RSSI。计算功率既可以在延迟多普勒域计算,也可以将第二延迟多普勒区域内的信号挑选出来,变换到时间频率域再计算功率。Calculate the power sum of the received signals at all grid points in the second delay Doppler region, and then divide the power sum by the coefficient t (the third coefficient), and record it as the first RSSI. The calculated power can be calculated in the delayed Doppler domain, or the signal in the second delayed Doppler region can be selected, transformed into the time-frequency domain, and then the power can be calculated.
所述第二延迟多普勒区域可以指用于测量信号质量的延迟多普勒区域,包含多个延迟和多普勒,可以将一个延迟多普勒帧的所有资源栅格都作为第二延迟多普勒区域。The second delay Doppler region may refer to a delay Doppler region used to measure signal quality, including multiple delays and Dopplers, and all resource grids of a delay Doppler frame may be used as the second delay Doppler area.
以图7的延迟多普勒帧为例,可以将所有M×N=18×12=216个栅格区域作为第二延迟多普勒区域,计算这第二延迟多普勒区域内所有格点上的接收信号的功率总和,记作第一RSSI。同样,对于图8的延迟多普勒帧,也可以将所有M×N=18×12=216个栅格区域作为第二延迟多普勒区域,计算这第二延迟多普勒区域内所有格点上的接收信号的功率总和,记作第一RSSI。这两种情况下,由于端口数不同,最后得到的第一RSSI也会不同。第二延迟多普勒域也可以选择一部分的延迟多普勒栅格,即第二延迟多普勒域包含的栅格数可以小于M×N。Taking the delayed Doppler frame in Figure 7 as an example, all M×N=18×12=216 grid areas can be used as the second delayed Doppler area, and all grid points in the second delayed Doppler area can be calculated The sum of the power of the received signals is recorded as the first RSSI. Similarly, for the delayed Doppler frame in Figure 8, all M×N=18×12=216 grid areas can also be used as the second delayed Doppler area, and the possessive grids in this second delayed Doppler area can be calculated. The sum of the power of the received signals at the point is recorded as the first RSSI. In these two cases, due to the different number of ports, the final first RSSI will be different. The second delayed Doppler domain may also select a part of the delayed Doppler grids, that is, the number of grids included in the second delayed Doppler domain may be less than M×N.
在一个实施例中,第二RSSI的计算方式可以为:In one embodiment, the calculation method of the second RSSI may be:
与第三RSRP的计算方式类似,可以计算K个上述第一RSSI的均值,记作第二
RSSI。这K个第一RSSI可以是基于连续的K个延迟多普勒帧获得的,也可以是基于周期出现的K个延迟多普勒帧获得的,也可以是基于任意的(间断的)K个延迟多普勒帧获得的。所述均值可以是线性平均得到的均值。也可以是加权平均得到的均值,即K个第一RSSI进行平均时赋予不同的权重。从K个第一RSSI计算出第二RSSI的操作也称为过滤。Similar to the calculation method of the third RSRP, the average of the K first RSSIs can be calculated and recorded as the second RSSI. The K first RSSIs can be obtained based on K consecutive delayed Doppler frames, or based on K delayed Doppler frames that appear periodically, or based on any (intermittent) K delayed Doppler frames. Delayed Doppler frames were obtained. The mean value may be a mean value obtained by linear averaging. It can also be the average value obtained by a weighted average, that is, different weights are given when averaging the K first RSSIs. The operation of calculating the second RSSI from the K first RSSIs is also called filtering.
可选地,延迟多普勒域信号强度指示可以定义为上述第一RSSI或者第二RSSI。Optionally, the delayed Doppler domain signal strength indication may be defined as the above-mentioned first RSSI or second RSSI.
可选地,延迟多普勒域信号强度指示RSSI可以定义为上述第一RSSI或者第二RSSI。Optionally, the delayed Doppler domain signal strength indication RSSI may be defined as the above-mentioned first RSSI or the second RSSI.
在一个实施例中,延迟多普勒域信号与干扰评估指标计算方式可以为:
In one embodiment, the delay Doppler domain signal and interference evaluation index calculation method can be:
其中,延迟多普勒域干扰功率是通过干扰测量获得的。RSRP的测量和干扰功率的测量可以是在同一个帧内实现,也可以在不同的帧实现。Among them, the delayed Doppler domain interference power is obtained through interference measurement. The measurement of RSRP and the measurement of interference power can be implemented in the same frame or in different frames.
RSRP的测量和干扰功率的测量在同一个帧内实现的情况下,与RSRP的第一延迟多普勒区域类似,干扰测量也需要一个第三延迟多普勒区域,在该第三延迟多普勒区域内计算干扰的功率总和,记作延迟多普勒域干扰功率。上述第一延迟多普勒区域与第三延迟多普勒区域不可重叠。图9是本申请实施例提供的第一信号的示意图之一,图9示出的是在同一个帧内实现RSRP的测量和干扰功率的测量的终端信号;如图9所示,以一个M=18,N=12的***为例,带斜杠的栅格区域为与RSRP测量对应的第一延迟多普勒区域(图9中即延迟方向3到8、多普勒方向4到9的矩形区域),带棱型网格的栅格区域为与干扰功率测量对应的第三延迟多普勒区域(图9中即延迟方向11到16、多普勒方向4到9的矩形区域)。When the measurement of RSRP and the measurement of interference power are implemented in the same frame, similar to the first delay Doppler area of RSRP, the interference measurement also requires a third delay Doppler area. The total power of the interference is calculated in the Doppler region and recorded as the delayed Doppler domain interference power. The above-mentioned first delayed Doppler area and the third delayed Doppler area cannot overlap. Figure 9 is one of the schematic diagrams of the first signal provided by the embodiment of the present application. Figure 9 shows a terminal signal that implements RSRP measurement and interference power measurement in the same frame; as shown in Figure 9, with an M =18, N=12 system as an example. The grid area with slashes is the first delay Doppler area corresponding to the RSRP measurement (in Figure 9, that is, delay directions 3 to 8 and Doppler directions 4 to 9 Rectangular area), the grid area with the prismatic grid is the third delayed Doppler area corresponding to the interference power measurement (in Figure 9, it is the rectangular area with delay directions 11 to 16 and Doppler directions 4 to 9).
RSRP的测量和干扰功率的测量在不同帧内实现的情况下,也是需要在第三延迟多普勒区域内计算干扰的功率总和,记作延迟多普勒域干扰功率。其中,第一延迟多普勒区域与第三延迟多普勒区域可以重叠也可以不重叠。图10是本申请实施例提供的第一信号的示意图之二;图11是本申请实施例提供的第一信号的示意图之三;图10和图11示出了RSRP的测量和干扰功率的测量在不同帧内实现时的终端信号,如图10和图11所示,描述了第一延迟多普勒区域与第三延迟多普勒区域完全重叠的情况,由于二者已经通过不同的帧区分开了,所以即使完全重叠,RSRP的测量与干扰功率的测量也不会相互影响。When the measurement of RSRP and the measurement of interference power are implemented in different frames, it is also necessary to calculate the total interference power in the third delayed Doppler region, which is recorded as delayed Doppler domain interference power. The first delayed Doppler area and the third delayed Doppler area may or may not overlap. Figure 10 is the second schematic diagram of the first signal provided by the embodiment of the present application; Figure 11 is the third schematic diagram of the first signal provided by the embodiment of the present application; Figures 10 and 11 show the measurement of RSRP and the measurement of interference power. The terminal signal when implemented in different frames, as shown in Figure 10 and Figure 11, describes the situation where the first delayed Doppler area and the third delayed Doppler area completely overlap, since the two have been distinguished by different frames is on, so even if they completely overlap, the measurement of RSRP and the measurement of interference power will not affect each other.
