Description

一种数据处理方法及其装置
本申请要求于2019年10月31日提交中国专利局、申请号为201911057386.9、申请名称为“一种数据处理方法及其装置”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。
技术领域
本申请涉及通信技术领域，尤其涉及一种数据处理方法及其装置。
背景技术
随着终端数量的飞速增长，基站能够与多个终端同时进行上行、下行数据传输。例如，多用户多输入多输出(multi-user multiple-input multiple-output，MU-MIMO)技术使得基站可以与多个终端同时利用相同的时频资源进行上行、下行数据传输，从而有利于提升系统容量。
多个终端与基站之间进行上行、下行数据传输之前，该多个终端需要向基站发送不同的随机接入信道(random access channel，RACH)信号，该基站检测到该多个终端各自发送的RACH信号之后，可以完成该多个终端的接入。基站接收到包括zadoff-chu序列(简称ZC序列)的信号时，可以表明接收到某终端发送的RACH信号。ZC序列由根序列经过循环移位得到，根序列中的元素满足如下关系式：
Figure PCTCN2020124676-appb-000001
其中，u为物理根序列号；i为该根序列中元素的索引，i的取值为0至N ZC-1，x u(i)为该根序列中元素索引为i的元素值，N ZC为ZC序列的长度，j为复数中的虚数符号。
但是，根据上述关系式得到的根序列的数量较少，相应的，得到的ZC序列的数量较少。随着小区接入的终端设备的数量增加，这样会导致随机接入过程中终端设备之间发生冲突的概率增大。
发明内容
本申请实施例提供一种数据处理方法及其装置，有利于得到较多不同的第一序列，从而有利于减小随机接入过程中终端设备之间发生冲突的概率。
第一方面，本申请实施例提供一种数据处理方法，该方法包括：第一终端设备根据参数组确定包含N个元素的第一序列，该参数组包括第一参数，第二参数和循环移位值，该第一序列由第二序列按照该循环移位值经过循环移位得到，该第二序列根据第一参数和第二参数确定；第一终端设备根据该第一序列向网络设备发送信号；其中，该第二序列中的元素满足：

其中，u 1为第一参数，u 1∈{1,2,…,P-1}；u 2为第二参数，u 2∈{0,1,2,…,P-1}；i为第二序列中元素的索引，i的取值为0至N-1，
Figure PCTCN2020124676-appb-000004
为第二序列中元素索引为i的元素值，N为第二序列的长度，j为复数中的虚数符号，P与N之间满足如下关系中的任一种：P为大于或等于N的最小质数；P为小于或等于N的最大质数；P为大于2×N的最小质数；P为小于2×N的最大质数；α为一个非零复数，

在该技术方案中，通过改变u1或者u2的取值，可以得到(P*(P-1))个不同的第二序列。相较于现有技术只能通过改变一个参数的值来获得不同的第二序列，本申请实施例通过改变u1或u2中任意一个参数的取值能得到不同的第二序列。可见，通过本申请实施例提供的第二序列中的元素满足的关系式可以得到更多不同的第二序列。进一步的，可以得到更多不同的第一序列，从而有利于减小随机接入过程中终端设备之间发生冲突的概率。另外，还可以将第一序列分配给更多的终端设备使用，从而有利于增大小区可以接入的终端设备的数量。

请参见图1，图1是本申请实施例公开的一种通信系统的架构示意图。如图1所示，该通信系统包括：网络设备101和第一终端设备102。其中，第一终端设备102为处于网 络设备101对应的小区的覆盖范围内的终端设备。
第一终端设备102可以根据参数组确定包含N个元素的第一序列，并根据该第一序列向网络设备101发送信号。网络设备101也可以根据该参数组确定出该第一序列，并在接收到第一信号之后，根据该第一序列和该第一信号，确定该第一信号是否包括根据该第一序列发送的信号。
需要说明的是，无论第一终端设备102是否向网络设备101发送信号，该网络设备101均可以接收到第一信号。若第一终端设备102向网络设备101发送信号，该网络设备101接收到的第一信号可以包括第一终端设备102发送的信号，可选的，该第一信号还可以包括噪声信号和/或其他终端设备向网络设备101发送的信号。若第一终端设备102未向网络设备101发送信号，该网络设备101接收到的第一信号不包括第一终端设备102发送的信号，可选的，该第一信号可以包括噪声信号和/或其他终端设备向网络设备101发送的信号。
还需要说明的是，图1所示通信系统仅包括一个终端设备(即第一终端设备102)仅用于举例，并不构成对本申请实施例的限定。在一种实现方式中，除了第一终端设备102以外，图1所示的通信系统还可以包括其他终端设备，该其他终端设备也处于网络设备101对应的小区的覆盖范围内。当网络设备101对应的通信系统包括多个终端设备(如第一终端设备102发送的信号和第二终端设备)时，第一终端设备102和第二终端设备(图1未示)可以分别确定对应的第一序列，并根据对应的第一序列分别向网络设备101发送信号。例如，第一终端设备102对应第一序列a，第二终端设备对应第一序列b。相应的，网络设备101接收到的第一信号可以包括信号1和信号2，其中，信号1是第一终端设备102根据第一序列a发送的信号，信号2是第二终端设备根据第一序列b发送的信号。其中，第一序列a和第一序列b不相同。第一序列a可以用于确定网络设备101接收到的第一信号是否包括根据该第一序列a发送的信号1，同理，第一序列b可以用于确定网络设备101接收到的第一信号是否包括根据该第一序列b发送的信号2。
其中，上述参数组包括第一参数，第二参数和循环移位值，该第一序列可以由第二序列按照该循环移位值经过循环移位得到，该第二序列根据第一参数和第二参数确定。该第二序列中的元素满足：

其中，u 1为第一参数，u 1∈{1,2,…,P-1}；u 2为第二参数，u 2∈{0,1,2,…,P-1}；i为第二序列中元素的索引，i的取值为0至N-1，
Figure PCTCN2020124676-appb-000012
为第二序列中元素索引为i的元素值，N为第二序列的长度，j为复数中的虚数符号，P为一个质数，α为一个非零复数，
Figure PCTCN2020124676-appb-000013
为一个实数。P与N之间满足如下关系中的任一种：P为大于或等于N的最小质数；P为小于或等于N的最大质数；P为大于2×N的最小质数；P为小于2×N的最大质数。
本申请实施例所述数据处理方法，可以应用于随机接入过程或者网络设备与终端设备之间的上、下行数据传输过程。当应用于随机接入过程中，网络设备101通过第一序列可以确定接收到的第一信号是否包括RACH信号。第一信号包括A个不同的RACH信号时，可以表示有A个不同的终端设备需要接入该网络设备101。
同理，当应用于网络设备与终端设备之间的上、下行数据传输过程中，若网络设备接收到的第一信号包括B个不同的数据信号(或者控制信号)，可以表示该网络设备接收到B个不同的终端设备发送的信号。进一步的，网络设备还可以通过与终端设备之间的交互信息对该网络设备和该终端设备之间的信道进行信道估计。其中，A、B为正整数。
其中，网络设备101可以是网络侧的一种用于发射或接收信号的实体，例如，网络设101可以是接入网设备(如基站)。第一终端设备102和第二终端设备可以是用户侧的一种用于接收或发射信号的实体，具体的，第一终端设备102和第二终端设备可以是用户设备(user equipment，UE)、远程终端、移动终端、无线通信设备、用户装置等，其中，用户设备可以是手机、台式电脑、笔记本电脑或其他可穿戴设备等。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请提供的数据处理方法及基于序列的信号传输的装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种数据处理方法的流程示意图。其中，步骤S201～步骤S202的执行主体为第一终端设备，或者为第一终端设备中的芯片，步骤S203～步骤S205的执行主体为网络设备，或者为网络设备中的芯片，以下以第一终端设备、网络设备为数据处理方法的执行主体为例进行说明。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：第一终端设备根据参数组确定包含N个元素的第一序列，该参数组包括第一参数，第二参数和循环移位值，该第一序列由第二序列按照该循环移位值经过循环移位得到，该第二序列根据第一参数和第二参数确定，该第二序列中的元素满足：
Figure PCTCN2020124676-appb-000014
或
Figure PCTCN2020124676-appb-000015
其中，u 1为第一参数，u 1∈{1,2,…,P-1}；u 2为第二参数，u 2∈{0,1,2,…,P-1}；i为第二序列中元素的索引，i的取值为0至N-1，
Figure PCTCN2020124676-appb-000016
为第二序列中元素索引为i的元素值，N为第二序列的长度，j为复数中的虚数符号，P为一个质数，α为一个非零复数，
Figure PCTCN2020124676-appb-000017
为一个实数，mod为求余运算。
其中，P是原始序列的长度，N和P均为正整数。通过上述第二序列中的元素满足的关系式和包含P个元素的原始序列，可以得到包含N个元素的第二序列。在本申请实施例中，P与N之间可以满足如下关系中的任一种：P为大于或等于N的最小质数；P为小于或等于N的最大质数；P为大于2×N的最小质数；P为小于2×N的最大质数；P为大于N/2的最小质数；P为小于N/2的最大质数。由P与N之间满足的关系可知，N可以为接近或等于P的一个值，即N可以大于P，也可以小于P。N也可以为接近2P的一个值，或者，N也可以为接近P/2(当P/2为整数时)的一个值。通过P与N之间满足的关系可知，第二序列和原始序列的长度相差不大，通过这种方式，可以使得第二序列依然具有原始序列的序列特征。可选的，N可以为139、839或者其他数值。
通过上述第二序列中的元素满足的关系式可知，通过改变u1或者u2的取值，可以得到(P*(P-1))个不同的第二序列。相较于现有技术只能通过改变一个参数的值来获得不同的第二序列，本申请实施例通过改变u1或u2中任意一个参数的取值能得到不同的第二序列。可见，通过本申请实施例提供的第二序列中的元素满足的关系式可以得到更多不同的第二序列。进一步的，可以得到更多不同的第一序列，从而有利于减小随机接入过程中终端设备之间发生冲突的概率。另外，还可以将第一序列分配给更多的终端设备使用，从而有利于增大小区可以接入的终端设备的数量。
在本申请实施例中，第一序列中的元素满足：
Figure PCTCN2020124676-appb-000018
在第一序列中的元素满足的关系式中，n为第一序列中元素的索引，N为第二序列的长度，C v为序列组中的循环移位值，v为C v的索引。上述第一序列中的元素满足的关系式表示：第一序列中元素索引为n的元素值是通过对第二序列中元素索引为n的元素值循环移位(如左移或右移)((n+C v)modN)位得到的。例如，若第二序列为0110，则对第二序列分别循环左移1位、2位和3位后，得到的序列分别为1100,1001,和0011。通过对第二序列循环移位v次，且每次移位的位数不同，可以得到v个不同的第一序列。又如，当第二序列为0110且C 0＝1、C 1＝3时，
Figure PCTCN2020124676-appb-000019
此时，第一序列中元素索引为0的元素值是通过对第二序列中元素索引为0的元素值循环左移1位得到的；
Figure PCTCN2020124676-appb-000020
此时，第一序列中元素索引为0的元素值是通过对第二序列中元素索引为0的元素值循环左移3位得到的。
在一种实现方式中，C v∈{0,1,2,…,N-1}，C v的实际取值可以是非连续的，但是v的 取值可以是连续的。具体的，{0,1,2,…,N-1}中的
Figure PCTCN2020124676-appb-000021
个取值可以组成C v的取值集合，v为C v在该取值集合中的索引，v的取值范围为
Figure PCTCN2020124676-appb-000022
任意两个v对应的C v值之间的差值大于或等于L，即任意两个循环移位值之间的差值大于或等于L。其中，
Figure PCTCN2020124676-appb-000023
表示向下取整符号，
Figure PCTCN2020124676-appb-000024
表示不超过N/L的最大整数。例如，N为51且L为10时，C v∈{0,1,2,…,50}，
Figure PCTCN2020124676-appb-000025
即C v的取值集合包括5个值，v的取值范围为[0，4]，C v的取值集合由C 0、C 1、C 2、C 3、C 4组成。具体的，C 0、C 1、C 2、C 3、C 4分别为0、10、20、30、40。需要说明的是，上述例子中，C 0的取值为0仅用于举例，在其他可行的实现方式中，C 0的取值还可以为1～9中的任意一个取值，根据C 0的取值可以相应地确定C v的取值集合中的C 1、C 2、C 3、C 4的取值。
在本申请实施例中，参数组可以由协议约定。在一种实现方式中，参数组可以由网络设备发送给第一终端设备。需要说明的是，网络设备可以向第一终端设备发送参数组，也可以通过多种方式向第一终端设备发送指示信息以指示该参数组。例如，网络设备向第一终端设备发送包括该参数组的信息，第一终端设备可以从该信息中提取出参数组。
在一种实现方式中，上述P、α和
Figure PCTCN2020124676-appb-000026
均可以由协议约定，或者可以由用户设置，本申请实施例对此不做限定。本申请实施例中提及的序列(如第一序列和第二序列)可以是被排成一列的对象(或元素、事件)，序列中的对象(或元素、事件)可以是一个字符或者频率点，本申请实施例对此不做限定。
步骤S202：第一终端设备根据该第一序列向网络设备发送信号。
在本申请实施例中，第一终端设备确定第一序列之后，可以根据该第一序列向网络设备发送信号。
在一种实现方式中，第一终端设备根据该第一序列向网络设备发送信号的具体实施方式可以为：第一终端设备对该第一序列进行快速傅立叶变换，得到频域序列；并将该频域序列映射到子载波上，得到信号；向网络设备发送该信号。
其中，第一序列是时域的一个序列，对该第一序列进行快速傅立叶变换(fast fourier transformation，FFT)，可以将该第一序列从时域变换为频域中的一个序列(即频域序列)。需要说明的是，第一终端设备通过对第一序列进行FFT仅用于举例，并不构成对本申请实施例的限定，在其他可行的实现方式中，第一终端设备还可以对该第一序列进行离散傅里叶变换(discrete fourier transform，DFT)，以将第一序列从时域变换为频域中的一个序列。
步骤S203：网络设备根据参数组确定包含N个元素的第一序列。
网络设备根据参数组确定包含N个元素的第一序列的执行过程与第一终端设备根据参数组确定包含N个元素的第一序列的执行过程相同，即步骤S203的执行过程可参见步骤S201的具体描述，此处不再赘述。
在一种实现方式中，网络设备可以分别向第一终端设备和第二终端设备发送参数组，发送给第一终端设备的参数组中的第一参数和第二参数与发送给第二终端设备的参数组中的第一参数和第二参数至少有一个不同。在一种实现方式中，发送给第一终端设备的参数 组中的第一参数和第二参数与发送给第二终端设备的参数组中的第一参数和第二参数均相同时，发送给第一终端设备的参数组中的循环移位值与发送给第二终端设备的参数组中的循环移位值之间的差值的绝对值大于第一数值(即前述L)，其中，第一终端设备和第二终端设备为位于同一小区中的不同终端设备。
第一数值和第二数值相同时，生成的第二序列相同，但是不同终端设备使用相同的第一序列时会导致冲突。因此，第一终端设备和第二终端设备使用的第一序列是对该第二序列进行不同位数的循环移位得到，这样可以使得第一终端设备和第二终端设备使用的第一序列不同。但是根据第一序列发送的信号在传输过程中会发生变化。具体的，第一终端设备与网络设备之间的距离，和第二终端设备与该网络设备之间的距离可能不同，因此第一终端设备和第二终端设备各自向该网络设备发送的信号到达该网络设备所需的传播时延不一样。当第一终端设备和第二终端设备使用的循环移位值之间的差值较小时，由于传播时延差，两个终端设备发射的信号到达该网络设备时可能是相同的，这样会导致网络设备无法区分第一终端设备和第二终端设备发射的信号。换言之，网络设备接收到终端设备(即第一终端设备、第二终端设备)发送的信号时，该信号中的第一序列发生了移位。例如，第一终端设备根据第一序列向网络设备发送信号1，经过传输，网络设备接收的第一终端设备发送的信号为信号2，根据信号2得到的序列是信号1中的第一序列(因传输)经过移位后得到的序列。
在一种实现方式中，在传输过程中第一序列发生的移位小于或等于第一数值。因此，发送给第一终端设备的参数组中的第一参数和第二参数与发送给第二终端设备的参数组中的第一参数和第二参数均相同时，发送给第一终端设备的参数组中的循环移位值与发送给第二终端设备的参数组中的循环移位值之间的差值的绝对值大于第一数值(即前述L)，可以避免网络设备接收到第一终端设备和第二终端设备各自发送的信号时，网络设备无法区分第一终端设备和第二终端设备各自发送的信号。以第一终端设备发送的信号为信号3，第二终端设备发送的信号为信号4，网络设备接收到的(第一终端设备发送的)信号为信号5，网络设备接收到的(第二终端设备发送的)信号为信号6为例。其中，信号3和信号4是根据相同的u1、u2和不同的循环移位值得到的，信号3对应的循环移位值x1与信号4对应的循环移位值x2之间的差值大于L。由于传输过程中信号发生的移位小于或等于L，因此，信号5对应的循环移位值x3与信号6对应的循环移位值x4之间的差值大于0，因此，网络设备可以区分出信号5和信号6。
在一种实现方式中，前述第一数值可以由第一终端设备和第二终端设备所处小区的半径确定，或者，第一数值可以由该小区对应的多径时延中的最大值确定。具体的，当第一终端设备未接收到时间提前量(time advance，TA)信息时，第一数值以由该小区的传播时延中的最大值确定，该小区的传播时延中的最大值可以根据该小区的半径确定。当第一终端设备接收到TA信息时，第一数值由该小区对应的多径时延中的最大值确定。
在一种实现方式中，网络设备可以分别向第一终端设备和第三终端设备发送参数组，发送给第一终端设备的参数组中的第一参数与发送给第三终端设备的参数组中的第一参数相同时，发送给第一终端设备的参数组中的第二参数和发送给第三终端设备的参数组中的第二参数之间的差值的绝对值大于第二数值，其中，第一终端设备和第三终端设备为位于 同一小区中的不同终端设备。可选的，第一终端设备、第二终端设备和第三终端设备位于同一小区。
在一种实现方式中，该第二数值可以由第一终端设备和第三终端设备所处小区对应的多普勒频移中的最大值(如d)确定，或者，该第二数值可以由该d以及用于承载第一终端设备发送的信号(或者第三终端设备发送的信号)的载波之间的间隔(如
Figure PCTCN2020124676-appb-000027
)确定。例如，第二数值为
Figure PCTCN2020124676-appb-000028
或
Figure PCTCN2020124676-appb-000029
其中，
Figure PCTCN2020124676-appb-000030
表示向上取整符号。通过这种方式，在不同终端设备的多普勒频移不同的情况下，可以确保网络设备仍能区分不同终端设备发送的信号。
步骤S204：网络设备接收第一信号。
具体的，网络设备可以在预设的时频资源上接收第一信号。需要说明的是，无论第一终端设备是否向网络设备发送信号，该网络设备均可以接收到第一信号。在一种实现方式中，第一信号可以包括第一终端设备发送的信号、其他终端设备(如第二终端设备和第三终端设备)发送的信号，和/或噪声信号。当第一信号包括第一终端设备发送的信号和其他终端设备发送的信号时，该第一信号可以是由第一终端设备发送的信号和其他终端设备发送的信号组成的混合信号。
在一种实现方式中，前述预设的时频资源可以根据应用场景进行配置。例如，当本申请实施例应用于随机接入过程时，该预设的时频资源可以是网络设备监听随机接入请求的时频资源。
步骤S205：网络设备根据该第一序列和该第一信号，确定该第一信号是否包括根据该第一序列发送的信号。
具体的，网络设备接收到第一信号之后，可以根据确定出的第一序列和该第一信号，确定该第一信号是否包括根据该第一序列发送的信号。
在一种实现方式中，网络设备根据该第一序列和该第一信号，确定该第一信号是否包括根据该第一序列发送的信号的具体实施方式可以为：网络设备对该第一信号中子载波承载的频域序列进行快速傅立叶反变换(inverse fast fourier transformation，IFFT)，得到时域序列；并对该第一序列和该时域序列进行相关处理，得到相关值；根据该相关值确定该第一信号是否包括根据该第一序列发送的信号。在一种实现方式中，对该第一序列和该时域序列进行相关处理，得到相关值的具体实施方式可以为：网络设备根据该第一序列和由传播可能带来的循环移位，确定该第一序列经(由传播带来的)可能的循环移位之后所得的序列；并将该序列与该时域序列进行相关，得到一组相关值。相应的，根据该相关值确定该第一信号是否包括根据该第一序列发送的信号的具体实施方式可以为：网络设备对该组相关值进行归一化处理(如噪声归一化处理)，得到一组归一化后的相关值；若该组归一化后的相关值中的最大值大于预设阈值，则网络设备确定第一信号包括根据该第一序列发送的信号。在一种实现方式中，若该组归一化后的相关值中的最大值小于或等于该预设阈值，则网络设备确定第一信号不包括根据该第一序列发送的信号。
当本申请实施例应用于随机接入过程中时，网络设备确定第一信号包括根据该第一序 列发送的信号可以表明：网络设备接收到一个终端设备发送的随机接入请求。进一步的，网络设备可以根据上述一组相关值中的最大值所对应的由传播带来的可能的循环移位，确定发送该随机接入请求的终端设备与网络设备之间的距离。进而，网络设备可以根据该距离，确定TA值，并将该TA值发送给(发送该随机接入请求的)终端设备。在一种实现方式中，网络设备可以根据预设的循环移位值和距离之间的对应关系，确定发送该随机接入请求的终端设备与网络设备之间的距离。在一种实现方式中，在该对应关系中，越小的循环移位值对应的距离越短。
需要说明的是，当第一终端设备对应的小区包括多个终端设备时，网络设备可以确定出多个第一序列，该多个第一序列为网络设备对应的小区中的终端设备可能使用的第一序列(即小区中的终端设备发送的信号可能包括的第一序列)。例如，网络设备对应的小区包括3个终端设备(如第一终端设备、第二终端设备和第三终端设备)时，网络设备可以确定出3个第一序列(如第一序列a、第一序列b和第一序列c)。通过将第一序列a与网络设备接收到的第一信号进行相关，进一步可以确定该第一信号是否包括根据该第一序列a发送的信号。同理，通过将第一序列b与网络设备接收到的第一信号进行相关，进一步可以确定该第一信号是否包括根据该第一序列b发送的信号。同理，通过将第一序列c与网络设备接收到的第一信号进行相关，进一步可以确定该第一信号是否包括根据该第一序列c发送的信号。
其中，预设阈值可以由网络设备默认设置，也可以是用户输入的一个经验值。具体的，第一序列的长度不同时，预设阈值可以不同。
需要说明的是，上述步骤中至少部分步骤之间不限制执行的先后顺序，例如，步骤S203可以先于步骤S202发生，本申请实施例不做限定。
在本申请实施例中，通过改变u1或者u2的取值，可以得到(P*(P-1))个不同的第二序列。相较于现有技术只能通过改变一个参数的值来获得不同的第二序列，本申请实施例通过改变u1或u2中任意一个参数的取值能得到不同的第二序列。可见，通过本申请实施例提供的第二序列中的元素满足的关系式可以得到更多不同的第二序列。进一步的，可以得到更多不同的第一序列，从而有利于减小随机接入过程中终端设备之间发生冲突的概率。另外，还可以将第一序列分配给更多的终端设备使用，从而有利于增大小区可以接入的终端设备的数量。
请参见图3，图3是本申请实施例提供的另一种数据处理方法的流程示意图，该方法详细描述了网络设备通过向第一终端设备发送第一参数组集合的方式为该第一终端设备配置参数组。其中，步骤S302～步骤S304的执行主体为第一终端设备，或者为第一终端设备中的芯片，步骤S301、步骤S305～步骤S308的执行主体为网络设备，或者为网络设备中的芯片，以下以第一终端设备、网络设备为数据处理方法的执行主体为例进行说明。该方法可以包括但不限于如下步骤：
步骤S301：网络设备向第一终端设备发送第一参数组集合，其中，该第一参数组集合包括于第二参数组集合。
在本申请实施例中，网络设备可以预先存储有第二参数组集合，该第二参数组集合包 括的参数组可以分配给网络设备对应的小区中的终端设备。具体的，网络设备可以为一个终端设备配置1个或多个参数组，此时该1个或多个参数组为该终端设备特有。当网络设备为一个终端设备配置1个参数组，且根据该参数组确定第一序列a时，若网络设备接收到的第一信号包括根据该第一序列a发送的信号时，可以表明该网络设备接收到该终端设备发送的信号。当网络设备为该终端设备配置第一参数组集合，该第一参数组集合包括多个参数组(如4个参数组)，且根据该4个参数组分别确定第一序列a～第一序列d时，根据第一序列a～第一序列d中的任意第一序列发送的信号可以表示2比特的信息，且根据第一序列a～第一序列d中的不同第一序列发送的信号可以表示不同的信息。例如，根据第一序列a～第一序列d中第一序列发送的信号表示的信息分别为：00、01、10、11。即若网络设备接收到的第一信号包括根据第一序列d发送的信号时，可以表明该网络设备接收到该终端设备发送的信号，且该信号包括的2比特信息为11。可见，生成更多的第一序列时，可以为终端设备配置更多的第一序列，从而有利于使得终端设备根据第一序列向网络设备发送的信号可以携带更多信息。
在本申请实施例中，网络设备还可以向除第一终端设备以外的其他终端设备(如第二终端设备和第三终端设备)发送第一参数组集合，即网络设备可以向不同的终端设备发送相同的参数组集合。此时，该第一参数组集合由第一终端设备、第二终端设备和第三终端设备共享。相应的，第一终端设备、第二终端设备和第三终端设备可以分别从该第一参数组集合中确定参数组，根据该参数组分别确定第一序列，并根据分别确定出的第一序列向网络设备发送信号。当网络设备接收到的第一信号包括根据该第一参数组集合中的某一参数组确定的第一序列对应的信号时，网络设备可以确定接收到第一终端设备、第二终端设备或第三终端设备中的某一个终端设备发送的信号，但无法确定具体的终端设备。需要说明的是，第一终端设备、第二终端设备和第三终端设备可能选择不同的参数组，也可能选择相同的参数组。在一种实现方式中，当网络设备向不同的终端设备发送相同的参数组集合时，该参数组集合包括的参数组数量较多。
在一种实现方式中，网络设备可以向不同的终端设备发送不同的参数组集合，且不同的参数组集合中包括的参数组完全不同。此时，终端设备接收到的参数组集合由该终端设备特有。当网络设备接收到的第一信号包括根据该参数组集合中的某一参数组确定的第一序列对应的信号时，网络设备可以确定接收到该终端设备发送的信号，且该信号还携带了具体的信息。在一种实现方式中，当网络设备向不同的终端设备发送不同的参数组集合时，该参数组集合包括的参数组数量可以较少。
在一种实现方式中，在第一参数组集合中，第一参数和第二参数均相同的任意两个参数组中的循环移位值之间的差值的绝对值大于第一数值。通过这种方式，当多个终端设备共享该第一参数组集合时，不同终端设备选择该第一参数组集合中的不同参数组，并进而根据所选择的参数组分别生成信号，并向网络设备发送时。可以避免由于传输过程导致的移位，使得网络设备不能区分出不同终端设备发送的信号。
在一种实现方式中，在第一参数组集合中，第一参数相同的任意两个参数组中的第二参数之间的差值的绝对值大于第二数值。通过这种方式，当多个终端设备共享该第一参数组集合时，不同终端设备选择该第一参数组集合中第一参数相同的不同参数组，并进而根 据所选择的参数组分别生成信号，并向网络设备发送时。可以确保不同终端设备的多普勒频移不同时，网络设备仍能区分不同终端设备发送的信号。
步骤S302：第一终端设备从该第一参数组集合中确定参数组。
具体的，第一终端设备接收到网络设备发送的第一参数组集合之后，可以从该第一参数组集合中确定参数组。在一种实现方式中，第一终端设备可以从该第一参数组集合中随机确定参数组，也可以按照其他第一终端设备预设的方式从第一参数组集合中确定参数组。可选的，在不同终端设备共享第一参数组集合的情况下，不同终端设备可以采用不同的方式从该第一参数组集合中确定参数组。通过这种方式，可以降低不同终端设备从该第一参数组集合中确定的参数组相同的概率，从而有利于降低不同终端设备之间发生冲突的概率。
步骤S303：第一终端设备根据该参数组确定包含N个元素的第一序列，该参数组包括第一参数，第二参数和循环移位值，该第一序列由第二序列按照该循环移位值经过循环移位得到，该第二序列根据第一参数和第二参数确定，该第二序列中的元素满足：

或

其中，u 1为第一参数，u 1∈{1,2,…,P-1}；u 2为第二参数，u 2∈{0,1,2,…,P-1}；i为第二序列中元素的索引，i的取值为0至N-1，
Figure PCTCN2020124676-appb-000033
为第二序列中元素索引为i的元素值，N为第二序列的长度，j为复数中的虚数符号，α为一个非零复数，
Figure PCTCN2020124676-appb-000034
为一个实数；P与N之间满足如下关系中的任一种：P为大于或等于N的最小质数；P为小于或等于N的最大质数；P为大于2×N的最小质数；P为小于2×N的最大质数。
步骤S304：第一终端设备根据该第一序列向网络设备发送信号。
需要说明的是，步骤S303～步骤S304的执行过程可分别参见图2中步骤S201～步骤S202的具体描述，此处不再赘述。
步骤S305：网络设备从第二参数组集合中确定参数组。
在本申请实施例中，由于第二参数组集合中的参数组可以分配给网络设备对应的小区中的终端设备，因此，该小区中的终端设备向网络设备发送的信号可能是根据该第二参数组集合中的任意一个参数组确定的第一序列生成的。所以，网络设备需要遍历根据第二参数组集合中的各个参数组确定的第一序列，才能确定是否接收到该网络设备对应的小区中的各个终端设备发送的信号。
在一种实现方式中，若第二参数组集合由第三参数组集合和第四参数组集合组成，该第三参数组集合中的每个参数组均发送给网络设备对应的小区中的终端设备，且第四参数组集合中的每个参数组均未发送给网络设备对应的小区中的任一终端设备时，网络设备可以从该第三参数组集合中确定参数组。需要说明的是，网络设备对应的小区中的任一终端设备向网络设备发送的信号中的第一序列，是根据从网络设备接收到的参数组集合中确定 的。由于第四参数组集合中的每个参数组均未发送给网络设备对应的小区中的任一终端设备，因此，该小区中的终端设备向网络设备发送的信号不可能是根据第四参数组集合中的参数组确定的第一序列生成的。网络设备遍历根据第三参数组集合中的各个参数组确定的第一序列，即可确定是否接收到该网络设备对应的小区中的各个终端设备发送的信号。
步骤S306：网络设备根据该参数组确定包含N个元素的第一序列。
步骤S307：网络设备接收第一信号。
步骤S308：网络设备根据该第一序列和该第一信号，确定该第一信号是否包括根据该第一序列发送的信号。
需要说明的是，步骤S306～步骤S308的执行过程可分别参见图2中步骤S203～步骤S205的具体描述，此处不再赘述。还需要说明的是，上述步骤中至少部分步骤之间不限制执行的先后顺序，例如，步骤S305可以先于步骤S304(或者步骤S302、步骤S303)发生，本申请实施例不做限定。
通过实施本申请实施例，网络设备可以向不同的终端设备发送不同的参数组集合。终端设备根据接收到的参数组集合中的参数组确定第一序列，并根据该第一序列向网络设备发送信号，不仅有利于网络设备确定是否接收到对应小区中的终端设备发送的信号，还能进一步确定终端设备发送的信号携带的具体信息。
请参见图4，图4是本申请实施例提供的又一种数据处理方法的流程示意图，该方法详细描述了第二参数组集合中的参数组的分组规则。其中，步骤S402～步骤S404的执行主体为第一终端设备，或者为第一终端设备中的芯片，步骤S401、步骤S405～步骤S408的执行主体为网络设备，或者为网络设备中的芯片，以下以第一终端设备、网络设备为数据处理方法的执行主体为例进行说明。该方法可以包括但不限于如下步骤：
步骤S401：网络设备向第一终端设备发送第一参数组集合，其中，该第一参数组集合包括于第二参数组集合，该第二参数组集合包括于备选参数组集合；该备选参数组集合包括一个或多个参数组子集，该备选参数组集合中各个参数组子集中的参数组的第一参数相同，该备选参数组集合中任意两个分别属于不同的参数组子集的参数组的第一参数不同，该备选参数组集合中的各个参数组子集均包括a个参数组；第二参数组集合包括b个参数组；当b<＝a时，b个参数组为该备选参数组集合中的任意一个参数组子集中的任意b个参数组；和/或当b>a时，b个参数组由c个参数组子集中的参数组和d个参数组组成，其中，c个参数组子集为该备选参数组集合中的任意c个参数组子集，d个参数组为该备选参数组集合中除该c个参数组子集以外的任意一个参数组子集中的任意d个参数组。其中，d<a。
在本申请实施例中，可以根据第一参数将参数组划分到不同的参数组子集中。备选参数组集合中的一个参数组子集由第一参数(即u1)相同的参数组组成，不同参数组子集包括的参数组数量相同。网络设备对应的小区优先使用同一参数组子集中的参数组，若一个参数组子集中的参数组数量不够，则继续使用备选参数组集合中除该参数组子集以外的其他参数组子集中的参数组，直到参数组数量满足该小区的要求。
例如，备选参数组集合包括M个参数组子集，每个参数组子集均包含A个参数组，且网络设备对应的小区需要B个参数组时，若A>＝B，则该小区使用一个参数组子集中的参 数组集合即可。如果A<B，则该小区使用的参数组可以按照如下方式组成：备选参数组集合中的
Figure PCTCN2020124676-appb-000035
个参数组子集中的所有参数组，和该备选参数组集合中的另一个参数组子集中的(B mod A)个参数组。通过这种方式，可以使得网络设备对应的小区优先使用同一参数组子集中的参数组。
在一种实现方式中，可以为网络设备对应的小区配置一个逻辑索引，不同逻辑索引对应不同的参数组，或者，不同逻辑索引对应的参数组中的第一参数和第二参数中的至少一个参数不同。网络设备可以根据该逻辑索引对应的第一参数和第二参数确定第二序列，若确定出的第二序列的数量小于小区所需的数量时，网络设备更新逻辑索引，并根据更新后的逻辑索引对应的参数组中的第一参数和第二参数继续确定第二序列，直至确定出的第二序列的数量满足小区要求。在一种实现方式中，逻辑索引为i时，更新后的逻辑索引可以为i+1。
以表1所示的逻辑索引与参数组中的第一参数和第二参数的对应关系为例，从表1中可见，第一参数相同的参数组对应的逻辑索引连续(例如，第一参数为1的3个参数组对应的逻辑索引为0～2)。通过这种方式，可以使得更新后的逻辑索引对应的参数组与更新前的逻辑索引对应的参数组中的第一参数相同，即更新后的逻辑索引对应的参数组与更新前的逻辑索引对应的参数组属于同一参数组子集。

1 1 1
2 1 2

4 2 1
5 2 2

7 3 1
8 3 2
需要说明的是，表1仅为举例，并不构成对本申请实施例的限定。以表2为例，在其他可行的实现方式中，第一参数相同的参数组对应的逻辑索引可以相互交换。例如，由表2可知，表1中第一参数为3的不同参数组对应的逻辑索引发生了交换。以第一参数相同的参数组为单位，第一参数不同的参数组对应的逻辑索引可以相互交换。例如，由表2可知，表1中第一参数为1的参数组对应的逻辑索引与第一参数为2的参数组对应的逻辑索引相互交换。需要说明的是，表1和表2以参数组包括第一参数和第二参数为例，表中并未示出循环移位值，但是并不构成对本申请实施例的限定。

在一种实现方式中，第一参数组集合包括e个参数组，其中，e<＝b；当b<＝a时，e个参数组为b个参数组中的任意e个参数组。当b>a，且e<＝d时，e个参数组为该d个参数组中的任意e个参数组，或者，该e个参数组为该c个参数组子集中的任意一个参数组子集中的任意e个参数组。当b>a，d<e<＝a时，e个参数组为该c个参数组子集中的任意一个参数组子集中的任意e个参数组，或者，e个参数组包括d个参数组和c个参数组子集中的任意一个参数组子集中的任意(e-b)个参数组。当b>a，e>a时，e个参数组由f个参数组子集中的所有参数组和g个参数组组成，其中，该f个参数组子集为c个参数组子集中的任意f个参数组子集，该g个参数组为c个参数组子集中除该f个参数组子集以外的任意一个参数组子集中的任意g个参数组，或者，该g个参数组为该d个参数组中的任意g个参数组(当g<d时)。通过这种方式，网络设备可以优先将第二参数组集合中的同一参数组子集中的参数组分配给终端设备。
在一种实现方式中，通过实施本申请实施例，确定出的第一序列的时域自相关为
