以下结合附图，详细说明本发明各实施例提供的技术方案。The technical solutions provided by various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

参见图1所示，本发明实施例提供一种参考信号的生成方法，应用于终端设备或网络侧设备。该方法包括：Referring to FIG. 1 , an embodiment of the present invention provides a method for generating a reference signal, which is applied to a terminal device or a network side device. The method includes:

步骤101：根据指示信息，将目标序列依次经过目标调制和离散傅里叶变换调制生成目标参考信号；Step 101: According to the instruction information, the target sequence is sequentially subjected to target modulation and discrete Fourier transform modulation to generate a target reference signal;

其中，目标序列的长度为8或16；指示信息用于指示发送端设备是否采用目标参考信号传输。Wherein, the length of the target sequence is 8 or 16; the indication information is used to indicate whether the sending end device uses the target reference signal for transmission.

可选的，在本发明实施例的参考信号的生成方法中，上述目标调制包括π/2-二进制相移键控BPSK(Binary Phase Shift Keying)调制、正交相移键控QPSK(QuadraturePhase Shift Keying)调制和8-相移键控PSK(Phase Shift Keying)调制中的至少一个。Optionally, in the method for generating a reference signal in the embodiment of the present invention, the above-mentioned target modulation includes π/2-binary phase shift keying BPSK (Binary Phase Shift Keying) modulation, quadrature phase shift keying QPSK (Quadrature Phase Shift Keying ) modulation and at least one of 8-phase shift keying PSK (Phase Shift Keying) modulation.

可以理解，针对序列长度不同的目标序列，可以适配不同的调制方式进行准确的调制，以稳定地生成该目标参考信号。It can be understood that for target sequences with different sequence lengths, different modulation modes can be adapted for accurate modulation, so as to stably generate the target reference signal.

可选的，上述目标序列属于从基于目标序列长度和目标调制方式确定的所有可能序列组成的初始序列集合中选出的目标计算机生成序列CGS(Computer GeneratedSequence)集合；进一步地，该目标CGS集合中的序列满足目标准则，即该目标序列满足目标准则，以使得基于该目标序列生成的目标参考信号符号具有较低的PAPR。其中，从初始序列集合中选取目标序列时，可以根据该目标准则遍历初始序列集合，以筛选出满足目标准则的CGS组成目标CGS集合，进而在目标CGS集合中选取用于生成目标参考信号的目标序列。Optionally, the above target sequence belongs to the target computer generated sequence CGS (Computer Generated Sequence) set selected from the initial sequence set consisting of all possible sequences determined based on the target sequence length and the target modulation mode; further, in the target CGS set The sequence of satisfies the target criterion, that is, the target sequence satisfies the target criterion, so that the target reference signal symbols generated based on the target sequence have a lower PAPR. Wherein, when selecting the target sequence from the initial sequence set, the initial sequence set can be traversed according to the target criterion to filter out CGSs that meet the target criterion to form the target CGS set, and then select the target CGS used to generate the target reference signal in the target CGS set sequence.

其中，目标准则基于序列符号的移位自相关均值、序列符号间的互相关均值、序列符号对应的时域符号峰均比PAPR和序列对应的参考信号序列的误块率BLER(Block ErrorRate)中的至少一个确定。Among them, the target criterion is based on the shifted autocorrelation mean value of the sequence symbols, the cross-correlation mean value between the sequence symbols, the peak-to-average ratio PAPR of the time domain symbols corresponding to the sequence symbols, and the block error rate BLER (Block ErrorRate) of the reference signal sequence corresponding to the sequence At least one of the OK.

可选的，在本发明实施例的参考信号的生成方法中，上述目标准则包含以下至少一项：Optionally, in the method for generating a reference signal in the embodiment of the present invention, the above target criterion includes at least one of the following:

集合中序列符号的移位自相关均值中的最大值小于或等于移位自相关均值阈值，移位自相关均值阈值为残余集合中序列符号的移位自相关均值中的最小值；The maximum value of the shifted autocorrelation mean values of the sequence symbols in the set is less than or equal to the shifted autocorrelation mean value threshold, and the shifted autocorrelation mean value threshold is the minimum value of the shifted autocorrelation mean values of the sequence symbols in the residual set;

集合中序列符号间的互相关均值中的最大值小于或等于互相关均值阈值，互相关均值阈值为残余集合中序列符号间的互相关均值中的最小值；The maximum value of the cross-correlation mean values between the sequence symbols in the set is less than or equal to the cross-correlation mean value threshold, and the cross-correlation mean value threshold is the minimum value among the cross-correlation mean values between the sequence symbols in the residual set;

集合中序列符号对应的时域符号PAPR的最大值小于或等于时域符号PAPR阈值，时域符号PAPR阈值为残余集合中序列符号对应的时域符号PAPR中的最小值；以及The maximum value of the time domain symbol PAPR corresponding to the sequence symbol in the set is less than or equal to the time domain symbol PAPR threshold, and the time domain symbol PAPR threshold is the minimum value in the time domain symbol PAPR corresponding to the sequence symbol in the residual set; and

其中，残余集合为目标CGS集合在初始序列集合中的补集。Among them, the residual set is the complement set of the target CGS set in the initial sequence set.

可以理解，从初始序列集合筛选出的部分序列满足上述目标准则，即满足如下条件之一：目标CGS集合中的序列为初始序列集合中序列符号的移位自相关均值相对小的那部分序列；目标CGS集合中的序列为初始序列集合中序列符号间的互相关均值相对小的那部分序列；目标CGS集合中的序列为初始序列集合中序列符号对应的时域符号PAPR相对小的那部分序列；目标CGS集合中的序列为初始序列集合中序列对应的参考信号序列的BLER相对小的那部分序列。如此，通过采用序列符号的移位自相关均值、序列符号间的互相关均值、序列符号对应的时域符号PAPR和序列对应的参考信号序列的BLER中的至少一个值低的序列作为用于生成目标参考信号的目标序列，可以改善或解决参考信号符号的PAPR相比于数据符号的PAPR较高的问题。It can be understood that the partial sequences screened from the initial sequence set meet the above target criteria, that is, one of the following conditions is met: the sequence in the target CGS set is the part of the sequence whose shifted autocorrelation mean value of the sequence symbols in the initial sequence set is relatively small; The sequence in the target CGS set is the part of the sequence whose cross-correlation mean value between the sequence symbols in the initial sequence set is relatively small; the sequence in the target CGS set is the part of the sequence in which the time domain symbol PAPR corresponding to the sequence symbol in the initial sequence set is relatively small ; The sequences in the target CGS set are the sequences in the initial sequence set that have a relatively small BLER of the reference signal sequence corresponding to the sequences in the initial sequence set. In this way, at least one sequence with a low value among the shifted autocorrelation mean value of the sequence symbol, the cross-correlation mean value between the sequence symbols, the time domain symbol PAPR corresponding to the sequence symbol, and the BLER of the reference signal sequence corresponding to the sequence is used as the sequence for generating The target sequence of the target reference signal can improve or solve the problem that the PAPR of the reference signal symbols is higher than that of the data symbols.

需要说明的是，目标参考信号因该参考信号的生成方法的执行主体即发送端设备的不同而有所区别，即因发送端设备的不同对应的目标参考信号有所区别，具体地，发送端设备可以包括终端设备或网络侧设备。It should be noted that the target reference signal is different due to the difference in the execution subject of the generation method of the reference signal, that is, the transmitting end device, that is, the target reference signal corresponding to the different transmitting end device is different. Specifically, the transmitting end Devices may include terminal devices or network side devices.
