技术领域Technical field

本申请实施例涉及通信技术领域，尤其涉及一种数据传输方法及装置。The embodiments of the present application relate to the field of communication technologies, and in particular, to a data transmission method and device.

背景技术Background technique

目前，通信***中，例如***长期演进(long term evolution，LTE)通信***中，支持物联网(internet of things，IoT)场景。IoT场景中，可以包括网络设备和终端设备两种IoT设备。IoT场景中，要求终端设备和网络设备能够提供广覆盖、且要求IoT设备价格低以及电池寿命长等特性。IoT场景中，IoT设备间传输的数据包的大小较小。如果IoT设备之间采用同步传输，以上行同步传输为例，网络设备可以通过控制信令向各终端设备发送其相应的定时提前(timing advance，TA)信息，各终端设备根据其定时提前信息调整发送上行数据时的发送时间，可以使得不同终端设备发送的上行数据到达网络设备的时间基本上是对齐的。由于终端设备的定时提前信息不是一直维持不变的，终端设备与网络设备需要不断的进行控制信令的交互来维持两者之间的同步，因此，IoT设备间传输较小的数据包时的信令开销是不可忽视的，此外，维持同步也会不断耗电减少IoT设备电池使用寿命。Currently, communication systems, such as the fourth-generation Long Term Evolution (LTE) communication system, support the Internet of Things (IoT) scenario. In the IoT scenario, there can be two types of IoT devices: network devices and terminal devices. In the IoT scenario, terminal devices and network devices are required to provide wide coverage, and low prices and long battery life are required for IoT devices. In the IoT scenario, the size of the data packets transmitted between IoT devices is small. If synchronous transmission is used between IoT devices, the upper line is an example of synchronous transmission. Network devices can send their corresponding timing advance (TA) information to each terminal device through control signaling. Each terminal device adjusts according to its timing advance information. The sending time when sending the uplink data can make the time when the uplink data sent by different terminal devices reach the network device is substantially aligned. Because the timing advance information of the terminal device is not always maintained, the terminal device and the network device need to continuously perform control signaling interactions to maintain synchronization between the two. Therefore, when transmitting smaller data packets between IoT devices, The signaling overhead cannot be ignored. In addition, maintaining synchronization will also continuously consume power to reduce the battery life of IoT devices.

鉴于此，IoT设备可以采用异步传输的方式来传输数据。采用异步传输时，以上行异步传输为例，不同终端设备发送的数据到达网络设备的时间可以不同(即不对齐)，因此网络设备不需要通过控制信令向各个终端设备发送TA信息。由于终端设备与网络设备间不需要进行控制信令的交互来维持同步，所以，当IoT设备间传输较小的数据包时通过异步传输可以减少信令开销，可以提高IoT设备的***容量，同时，异步传输可以更加省电，提高电池使用寿命。In view of this, IoT devices can use asynchronous transmission to transmit data. When asynchronous transmission is used, the above asynchronous transmission is used as an example. The data sent by different terminal devices can reach the network devices at different times (that is, they are not aligned). Therefore, network devices do not need to send TA information to each terminal device through control signaling. Because terminal devices and network devices do not need to perform control signaling interaction to maintain synchronization, when transmitting smaller data packets between IoT devices, asynchronous transmission can reduce signaling overhead and increase the system capacity of IoT devices. Asynchronous transmission can save more power and improve battery life.

但是，异步传输时，例如对于上行异步传输，不同终端设备发送的数据到达网络设备的时间可能不同。此时，终端设备使用频域资源向网络设备进行数据传输时，如果不同终端设备的频域资源是频分的，且分配给不同终端设备的频域资源对应的频点比较接近，很容易出现下述情况：第一终端设备发送的数据的能量可能泄露到第一终端设备的频域资源以外的带宽中，例如泄露到与第一终端设备相邻的第二终端设备的频域资源中，该泄露的能量可能会干扰与第一终端设备相邻的第二终端设备的数据传输，使该相邻的第二终端设备进行数据传输时的错误率提高，从而降低了数据传输的速率。终端设备发送的数据的能量泄露到该终端设备的频域资源以外的部分可以被称为带外(out-of-band，OOB)数据或带外泄露(out-of-band emission，OOB emission)。带宽数据或者带外泄露还可以简称为OOB。因此，为了支持IoT场景下的异步传输，需要设计符合异步传输的低OOB的波形，以实现低OOB的数据传输。进一步的，如果该低OOB的波形的峰均功率比(peak to average power ratio，PAPR)比较高，那么该低OOB波形经过非线性功率放大器(power amplifier，PA)后OOB会提升，不能很好的保持波形的低OOB特性。因此，为支持异步传输，需要设计符合异步传输的低OOB且低PAPR的波形，以实现低OOB且低PAPR的数据传输。However, during asynchronous transmission, for example, for uplink asynchronous transmission, the time when data sent by different terminal devices reaches the network device may be different. At this time, when the terminal device uses frequency domain resources to transmit data to the network device, if the frequency domain resources of different terminal devices are frequency-divided, and the frequency points corresponding to the frequency domain resources allocated to different terminal devices are relatively close, it is easy to appear In the following case: the energy of the data sent by the first terminal device may leak to a bandwidth other than the frequency domain resources of the first terminal device, for example, the frequency domain resources of a second terminal device adjacent to the first terminal device, The leaked energy may interfere with the data transmission of the second terminal device adjacent to the first terminal device, increase the error rate when the adjacent second terminal device performs data transmission, and reduce the data transmission rate. The energy leakage of the data sent by the terminal equipment to the frequency domain resources of the terminal equipment can be called out-of-band (OOB) data or out-of-band leakage (OOB emission) . Bandwidth data or out-of-band leakage can also be referred to as OOB for short. Therefore, in order to support asynchronous transmission in the IoT scenario, it is necessary to design a low OOB waveform that conforms to asynchronous transmission to achieve low OOB data transmission. Further, if the peak-to-average power ratio (PAPR) of the low OOB waveform is relatively high, the low OOB waveform will be improved after passing through a non-linear power amplifier (PA), which is not very good. Low OOB characteristic of keeping the waveform. Therefore, in order to support asynchronous transmission, it is necessary to design a waveform with low OOB and low PAPR that conforms to asynchronous transmission, so as to realize data transmission with low OOB and low PAPR.

基于该数据传输方法，经过滤波，可以使每个时域符号上发送的第n个时域数据与多个其他时域符号的第n个时域数据相关，从而保证了不同时域符号上传输的数据的相关性与连续性，降低了OOB。同时，相比现有将时域符号对应的时域数据与滤波器进行线性卷积(linear convolution)以降OOB的方式，采用本申请实施例提供的滤波方式得到s _l,0中第n个数据时，可以减少乘法运算，因此采用本申请实施例提供的滤波方式得到的发送数据s _l,0的PAPR更低。 In a first aspect, an embodiment of the present application provides a data transmission method.

如图3所示，该方法可以包括步骤301～步骤303：As shown in FIG. 3, the method may include steps 301 to 303:

步骤301：对于在时域符号l′上传输的调制数据d _l′，根据调制数据d _l′得到长度为N的数据

或者还可以描述为：根据调制数据d _l′得到长度为N的数据

其中，d _l′是在时域符号l′上传输的调制数据，d _l′还可以被称为时域符号l′对应的调制数据。其中，d _l′中包含一个调制数据。 Step 301: For the modulation data d _{l ′} transmitted on the time domain symbol l ′, obtain data of length N according to the modulation data d _{l ′} .

At this time, the value of l ′ can be from 0 to 13, that is, l ′ can be from 0 to 13. When the subcarrier interval is 30kHz, there are 2 time slots in 1ms, that is, 28 time domain symbols. At this time, the value of l ′ can range from 0 to 27, that is, l ′ can be 0 to 27. Any integer value between.

由于一个时域符号传输的是一个调制数据，因此上述调制方式可以指不同时域符号传输的调制数据之间满足配置的调制方式的特征。例如，以Pi/2-BPSK调制为例，其特征为相邻两个调制数据点之间的幅度相同，相位相差90度或者270度，因此，若时域符号0上传输的调制数据为1，则时域符号1上传输的调制数据可以为j或者-j，时域符号2上传输的调制数据可以为1或者-1，即时域符号0、时域符号1、时域符号2中相邻两个时域符号上传输的调制数据之间的相位相差90度或270度，满足Pi/2-BPSK调制。Since a time-domain symbol transmits a modulation data, the above-mentioned modulation method may refer to a characteristic of a modulation method that satisfies a configuration among modulation data transmitted by different time-domain symbols. For example, taking Pi / 2-BPSK modulation as an example, it is characterized by the same amplitude between two adjacent modulation data points and a phase difference of 90 degrees or 270 degrees. Therefore, if the modulation data transmitted on the time domain symbol 0 is 1 , Then the modulation data transmitted on time domain symbol 1 can be j or -j, and the modulation data transmitted on time domain symbol 2 can be 1 or -1.

可选地，可以根据n与k确定α _n，如：α _n＝2π×n×k/N。其中，k可以是预配置的；当图3所示方法由终端设备执行时，网络设备也可以通过信令将k配置给终端设备。本申请实施例中，网络设备配置给不同终端设备的k可以不同或者相同。当α _n＝2π×n×k/N时，将长度为N的数据

进行FFT转换为频域数据，则得到的频域数据中索引为k的数据为d _l′，剩余索引的数据为0。如此，当不同终端设备配置的k不同时，不同终端设备在相同时域符号上传输的数据可以映射到不同的子载波上，即不同终端设备在频域资源是频分的。 Optionally, α _n may be determined according to n and k, such as: α _n = 2π × n × k / N. Among them, k may be pre-configured; when the method shown in FIG. 3 is executed by the terminal device, the network device may also configure k to the terminal device through signaling. In the embodiment of the present application, k configured by the network device to different terminal devices may be different or the same. When α _n = 2π × n × k / N, the data of length N will be

Each data d _{l ′} multiplied by a phase factor e ^{j2π × n × k / N is} equivalent to mapping the modulation data d _{l ′} to a subcarrier with a subcarrier index k (referred to as subcarrier k), and other N- The data on 1 subcarrier is 0, and then the IFFT transform is performed on the data on the N subcarriers:

When k = k ',

When k ≠ k ',

In contrast, as the inverse process of IFFT transformation, if the data of length N is

FFT is converted into frequency domain data, then the data of index k in the obtained frequency domain data is d _{l ′} , and the data of the remaining indexes is 0. In this way, when different terminal equipments have different k configurations, data transmitted by different terminal equipments on the same time domain symbol can be mapped to different subcarriers, that is, different terminal equipments are frequency-divided in frequency domain resources.

可选的，还可以根据n、k以及相位偏移量确定α _n，其中，相位偏移量可以为A或者A _k，A为实数，例如，A可以为固定常数，如：A可以为1/2或者1。再例如，A可以是预配置的；当图3所示方法由终端设备执行时，A也可以是由网络设备通过信令配置给终端设备的，不同终端设备分配的A可以相同也可以不同。示例性地，A _k可以根据k确定，如：通过表达式A _k＝A·k确定A _k，A如上所述，不再赘述；A _k也可以是预配置的；当图3所示方法由终端设备执行时，A _k还可以是网络设备通过信令配置给终端设备的，为不同终端设备分配的A _k可以相同也可以不同。 Optionally, α _n can also be determined according to n, k, and a phase offset, where the phase offset can be A or A _k and A is a real number. For example, A can be a fixed constant, such as: A can be 1 / 2 or 1. As another example, A may be pre-configured; when the method shown in FIG. 3 is executed by a terminal device, A may also be configured by the network device to the terminal device through signaling. A assigned by different terminal devices may be the same or different. Exemplarily, A _k can be determined according to k, such as: A k is determined by the expression A _k = A · _k , and A is as described above, and will not be repeated; A _k may also be pre-configured; when the method shown in FIG. 3 When executed by the terminal device, _Ak may also be configured by the network device to the terminal device through signaling. The _Ak allocated to different terminal devices may be the same or different.

示例性地，

当A为整数时，将长度为N的数据

中的每个数据d _l′乘以相位因子e ^{j2π×n×(k+A)/N}等效于将调制数据d _l′映射到子载波k+A的子载波上传输，剩余N-1个子载波上的数据为0。如此，当不同终端设备配置的k不同时，不同终端设备在相同时域符号上传输的数据可以映射到不同的子载波上，即不同终端设备在频域资源是频分的。或者， By way of example,

Each data d _{l ′} multiplied by the phase factor e ^{j2π × n × (k + A) / N is} equivalent to mapping the modulation data d _{l ′} to the subcarrier k + A for transmission, and the remaining N-1 The data on each subcarrier is 0. In this way, when different terminal equipments have different k configurations, data transmitted by different terminal equipments on the same time domain symbol can be mapped to different subcarriers, that is, different terminal equipments are frequency-divided in frequency domain resources. or,

示例性地，

中的每个数据d _l′乘以相位因子

等效于将调制数据d _l′映射到子载波索引为k+A _k的子载波上传输，剩余N-1个子载波上的数据为0。如此，当不同终端设备配置的A _k相同，k不同时，不同终端设备在相同时域符号上传输的数据可以映射到不同的子载波上，即不同终端设备在频域资源是频分的，同时，因A _k为k的倍数，各个终端设备偏移子载波k的程度会随着k的增大而增大，所以，可以通过采用相应的A _k取值来调整不同终端设备映射的频域位置之间的间隔，即调整终端设备的保护带的频域带宽大小。 By way of example,

A _k = A × k, when A is an integer, the data of length N

Each data in d _{l ′} times the phase factor

It is equivalent to mapping the modulation data d _{l ′} to a subcarrier with a subcarrier index k + A _k for transmission, and the data on the remaining N-1 subcarriers is 0. In this way, when A _k configured by different terminal devices is the same and k is different, data transmitted by different terminal devices on the same time domain symbol can be mapped to different subcarriers, that is, different terminal devices are frequency-divided in the frequency domain resources. At the same time, because _Ak is a multiple of k, the degree to which each terminal device is offset from the subcarrier k will increase as k increases. Therefore, the frequency of different terminal device mappings can be adjusted by using the corresponding value of _Ak . The interval between the domain positions, that is, the frequency domain bandwidth of the guard band of the terminal device is adjusted.

例如：假设终端设备1分配的k为1，终端设备2分配的k为3，A＝1，若采用相位因子e ^{j2π×n×(k+A)/N}旋转各个终端设备的调制数据，则可以将终端设备1的调制数据映射到子载波2上，将终端设备2的调制数据映射到子载波4上，此时，终端设备1与终端设备2间隔2个子载波；若采用相位因子

旋转各个终端设备的调制数据，A _k＝1·k，则可以将终端设备1的调制数据映射到子载波2上，将终端设备2的调制数据映射到子载波6上，此时，终端设备1与终端设备2间隔4个子载波，增大了二者映射的频率位置之间的间隔。 For example: Suppose k assigned by terminal device 1 is 1, k assigned by terminal device 2 is 3, and A = 1. If the phase factor e ^{j2π × n × (k + A) / N is used to} rotate the modulation data of each terminal device, then The modulation data of terminal device 1 can be mapped to subcarrier 2 and the modulation data of terminal device 2 can be mapped to subcarrier 4. At this time, terminal device 1 and terminal device 2 are separated by 2 subcarriers; if a phase factor is used

Rotate the modulation data of each terminal device, A _k = 1 · k, then you can map the modulation data of terminal device 1 to subcarrier 2, and the modulation data of terminal device 2 to subcarrier 6. At this time, the terminal device 1 and terminal device 2 are separated by 4 subcarriers, which increases the interval between the frequency positions mapped by the two.

上述实现中，重复、相位旋转操作采用离散的表示方式(即离散的表达式)，可替换的，也可以采用连续的表示方式(即连续的表达式)得到重复、相位旋转操作等各操作的输出数据。当采用连续的表示方式得到各操作的输出数据时，可以换将离散的表达式中的离散索引(比如n)替换为连续索引t，将离散数据长度N替换为时间长度T，其中T＝N×T _s。在本申请实施例中，T _s为时间单位因子，可以预定义，或者，由网络设备通过信令配置给终端设备。例如，子载波间隔为15kHz，N＝2048时，T _s的值为1/(15×1000×2048)。例如重复操作的输出数据

Alternatively, continuous representations (that is, continuous expressions) can also be used to obtain the operations of repetitions, phase rotations, and other operations Output Data. When continuous output is used to obtain the output data of each operation, the discrete index (such as n) in the discrete expression can be replaced by the continuous index t, and the discrete data length N can be replaced by the time length T, where T = N × T _s . In the embodiment of the present application, T _s is a time unit factor, which may be predefined or configured by a network device to a terminal device through signaling. For example, when the subcarrier interval is 15 kHz and N = 2048, the value of T _s is 1 / (15 × 1000 × 2048). Output data such as repeated operations

For example, L ₀ × N = 8192 means that the filter coefficient C ₀ contains 8192 coefficient values.

C ₀(n+offset-l′×N)是滤波器系数C ₀中的第n+offset-l′×N个值。可选地，k2-k1的取值可以与滤波器长度L ₀×N中L ₀的取值有关，如：k2-k1＝L ₀-1。可选的，k2的取值可以为l，k1＝l-(L ₀-1)；或者，k1的取值可以为l，k2＝l+(L ₀-1)；或者，k1、k2取l之外的其他值，不予限制。 C ₀ (n + offset-l ′ × N) is an n + offset-l ′ × N value in the filter coefficient C ₀ . Alternatively, k2-k1 values may filter length L ₀ × N ₀ of the value L related, such _{as: k2-k1 = L 0 -1} . Optionally, the value of k2 can be 1, k1 = l- (L ₀ -1); or, the value of k1 can be 1, k2 = l + (L ₀ -1); or, k1, k2 can be 1 Any value other than is not limited.

It is equivalent to multiplying the n-th data of k2-k1 + 1 time-domain symbols with corresponding filter coefficients, and adding the multiplied result to obtain the n-th data transmitted on time-domain symbol l.

例如，假设offset为l×N、k2为l、k1为l-(L ₀-1)，则

即将时域符号l的第n个数据数据与时域符号l之前的L ₀-1个时域符号的第n个数据与相应的滤波器系数进行相乘，并将相乘后的结果相加后得到时域符号l上传输的第n个数据。具体的，该过程可以通过图3a所示的滤波器来实现： For example, suppose offset is l × N, k2 is l, and k1 is l- (L ₀ -1), then

That is, the n-th data of the time-domain symbol l is multiplied by the corresponding filter coefficients with the n-th data of the L ₀ -1 time-domain symbols before the time-domain symbol l, and the results of the multiplication are added. Then, the nth data transmitted on the time domain symbol l is obtained. Specifically, this process can be implemented by the filter shown in FIG. 3a:

其中，T＝N×T _s，T _s为时间单位因子，T _s可以预定义，或者由网络设备通过信令配置给终端设备。例如，子载波间隔为15kHz，N＝2048时，T _s的值为1/(15×1000×2048)。可以知道，以

For example, when the subcarrier interval is 15 kHz and N = 2048, the value of T _s is 1 / (15 × 1000 × 2048). Can know that

When discrete sampling of C ₀ (t), the results obtained are consistent with C ₀ (n).

步骤303：发送数据s _l,0。 Step 303: Send data s _{l, 0} .

在时域符号l上发送s _l,0。相应地，网络设备在时域符号l上接收s _l,0。 Send s _{l, 0} on the time domain symbol l. Accordingly, the network device receives s _{l, 0} on the time domain symbol l.

在图3所示的方案中，发送s _l,0时，可以不添加循环前缀(cyclic prefix，CP)，每个时域符号的长度均为N。当采用本申请实施例提供的滤波方式进行滤波操作时，滤波操作的输入数据

时延N长度后，对应的正好是前一个时域符号的第n个数据

以此类推，可以获取到k2-k1+1个时域符号(即L ₀个时域符号)的第n个数据，将k2-k1+1个时域符号的第n个数据点乘对应的滤波器系数后相加合并得到时域符号l上传输的第n个数据，例如时域符号l上传输的第n个数据与L ₀-1个其他时域符号的第n个数据相关，可以保证不同时域符号上传输的数据的相关性与连续性。由于，OOB的性能主要和不同时域符号上传输的数据之间的相关性、连续性有关，所以，图3中所述保证不同时域符号上传输的数据的相关性与连续性的滤波方式可以降低传输数据的OOB。同时，相比现有将时域符号对应的时域数据与滤波器进行线性卷积以降OOB的方式，采用本申请实施例提供的滤波方式得到s _l,0中第n个数据时，所采用的乘法运算较少，因此采用本申请实施例提供的滤波方式得到的发送数据s _l,0的PAPR更低。 In the solution shown in FIG. 3, when sending s _{1, 0} , a cyclic prefix (CP) may not be added, and the length of each time domain symbol is N. When a filtering operation is performed by using the filtering method provided in the embodiment of the present application, input data of the filtering operation

After the delay N length, the corresponding is exactly the nth data of the previous time domain symbol

By analogy, the n-th data of k2-k1 + 1 time-domain symbols (that is, L ₀ time-domain symbols) can be obtained, and the n-th data point of k2-k1 + 1 time-domain symbols is multiplied by the corresponding The filter coefficients are added and combined to obtain the n-th data transmitted on the time-domain symbol l, for example, the n-th data transmitted on the time-domain symbol l is related to the n-th data of L ₀ -1 other time-domain symbols. Relevance and continuity of data transmitted on different time domain symbols are guaranteed. Because the performance of OOB is mainly related to the correlation and continuity between data transmitted on different time-domain symbols, the filtering method described in Figure 3 to ensure the correlation and continuity of data transmitted on different time-domain symbols Can reduce OOB of transmitted data. At the same time, compared with the existing method of linearly convolving time-domain data corresponding to time-domain symbols with a filter to reduce OOB, the filtering method provided in the embodiment of the present application is used to obtain the nth data in s _{l, 0} . There are fewer multiplication operations, so the PAPR of the transmitted data s _{l, 0} obtained by using the filtering method provided in the embodiment of the present application is lower.

Where s _{l, 0} (n) is the nth data in s _{l, 0} ,

发送数据s _l,0。 Send data s _{l, 0} .

或者，还可以描述为，对时域符号l′上传输的调制数据d _l′进行重复、相位旋转、滤波得到长度为N的数据s _l,0，发送数据s _l,0。 Alternatively, it can also be described as: the modulation data d _{l ′} transmitted on the time domain symbol l ′ is repeated, phase rotated, and filtered to obtain data S _{1,0 of} length N _, and the transmitted data s _1,0 .

其中，重复、相位旋转、滤波以及相位因子等可以参照图3对应的实施例中所述，不再赘述。上述图4a中重复、相位旋转、滤波操作同样可以采用连续的表示方式来表示，具体的，参考图3所示实施例中的实现，这里不再赘述。如此，可以将待发送数据经过重复、相位旋转映射到时频资源中的资源单元(resource element，RE)，并经滤波降低待发送数据的OOB，实现待发送数据的低OOB传输。The repetition, phase rotation, filtering, and phase factor can be referred to in the embodiment corresponding to FIG. 3 and will not be described again. The repetitive, phase rotation, and filtering operations in the foregoing FIG. 4a can also be expressed in a continuous manner. Specifically, referring to the implementation in the embodiment shown in FIG. 3, details are not described herein again. In this way, the data to be transmitted can be mapped to resource elements (REs) in the time-frequency resource through repetition and phase rotation, and the OOB of the data to be transmitted can be reduced by filtering, and low OOB transmission of the data to be transmitted can be realized.

需要说明的是，本申请实施例中，在重复操作中还可以乘以常数N _scale来调整调制数据d _l′的功率大小，如：

其中，N _scale为实数，N _scale可以是预定义的值，也可以由网络设备通过信令配置给终端设备。特殊的，N _scale＝1等效于对调制数据d _l′不进行功率调整。 It should be noted that in the embodiment of the present application, the power of the modulation data d _{l ′} can also be adjusted by multiplying the constant N _scale in repeated operations, such as:

Among them, N _scale is a real number, and N _scale may be a predefined value, or may be configured by a network device to a terminal device through signaling. In particular, N _scale = 1 is equivalent to no power adjustment for the modulation data d _{l ′} .

因图4a中的重复、相位旋转可以等效于将调制数据d _l′映射到第k个子载波或者距离子载波k一定偏移量的其他子载波上，其它N-1个子载波上的数据为0，然后对这个N个子载波上的数据进行IFFT变换。所以，可替换的，图4a中对时域符号l′上传输的调制数据d _l′进行重复、相位旋转可以等效为对时域符号l′上传输的调制数据d _l′进行频域资源映射、IFFT。具体的，该实现过程如图4b所示。 Because the repetition and phase rotation in Figure 4a can be equivalent to mapping the modulation data d _{l ′} to the k-th subcarrier or other subcarriers with a certain offset from the subcarrier k, the data on the other N-1 subcarriers is 0, and then IFFT transform the data on the N subcarriers. So, alternatively, the modulation data d _{l ′} transmitted on the time-domain symbol l ′ in FIG. 4 a is repeated, and the phase rotation may be equivalent to performing frequency-domain resources on the modulation data d _{l ′} transmitted on the time-domain symbol l ′. Mapping, IFFT. Specifically, the implementation process is shown in FIG. 4b.

图4b为本申请实施例提供的又一种数据传输方法原理框图，如图4b所示，该发送数据的过程包括：将时域符号l′上传输的对调制数据d _l′进行频域资源映射，得到长度为N的数据

其中，调制数据d _l′映射在子载波k位置上，除子载波k之外的其他N-1个子载波上的数据为0，即： FIG. 4b is a schematic block diagram of another data transmission method according to an embodiment of the present application. As shown in FIG. 4b, the process of sending data includes: performing frequency domain resources on the modulation data d _{l ′} transmitted on the time domain symbol l ′. Map to get data of length N

The modulation data d _{l ′ is} mapped on the position of the subcarrier k, and the data on the N-1 subcarriers except the subcarrier k is 0, that is:

或者，还可以描述为，对时域符号l′上传输的调制数据d _l′进行频域资源映射、IFFT、滤波得到长度为N的数据s _l,0，发送数据s _l,0。 Alternatively, it can also be described as _: performing frequency-domain resource mapping, IFFT, and filtering on the modulation data d _{l ′} transmitted on the time-domain symbol l ′ to obtain data s _{l, 0 of} length N _, and sending the data s _{l, 0} .

其中，k的相关描述可参照步骤301中所述，不再赘述。For the related description of k, refer to the description in step 301, which will not be repeated.

同步骤301中将调制数据映射到子载波的方式类似，图4b中也可以通过频域资源映射，将调制数据d _l′映射到偏移子载波k一定距离的其他子载波(如：子载波k+A或者子载波k+A _k)上，其中，A、A _k的相关描述可参照步骤301中所述，不再赘述。 Similar to the method of mapping the modulation data to the subcarriers in step 301, the modulation data d _{l ′} can also be mapped to other subcarriers (such as subcarriers) offset by a certain distance from the subcarrier k through frequency domain resource mapping in FIG. 4b. k + A or subcarrier k + A _k ), where related descriptions of A and A _k can be referred to in step 301 and will not be described again.

图4b实现中IFFT变换得到的输出数据同样可以采用连续的表示方式来表示。例如，IFFT变换的输出数据

中第t个时刻的数据

可以表示为： The output data obtained by the IFFT transformation in the implementation of FIG. 4b can also be expressed in a continuous manner. For example, the output data of an IFFT transform

滤波操作的输出数据同样可以采用连续的表示方式来表示。例如，s _l,0中第t个时刻的数据s _l,0(t)可以表示为

可选的，offset可以为l×T或者

以

对

s _l,0(t)进行离散采样时，得到的结果与离散表示形式的结果

s _l,0(n)是一致的。 The output data of the filtering operation can also be expressed in a continuous manner. For _example, s _l, s _l ₀ data in the t-th _{time, 0} (t) can be expressed as

Optionally, the offset can be l × T or

To

Correct

需要说明的是，IFFT变换操作过程中还可以乘以常数N _scale来调整

的功率大小，如：

其中，N _scale可以是预定义的值，也可以由网络设备通过信令配置给终端设备。特殊的，N _scale＝1等效于对d _l'×e ^j2π×k×n/N不进行功率调整。 It should be noted that during the IFFT transform operation, it can also be adjusted by multiplying the constant N _scale .

Power level, such as:

The N _scale may be a predefined value, or may be configured by the network device to the terminal device through signaling. In particular, N _scale = 1 is equivalent to no power adjustment for d _{l ′} × e ^{j2π × k × n / N.}

需要说明的是，本申请实施例中，IFFT只是一种傅里叶反变换的实现方式，不排除其他可能的实现。示例性的，IFFT也可以是离散傅里叶反变换(inverse discrete fourier transform，IDFT)。It should be noted that, in the embodiment of the present application, IFFT is only an implementation manner of inverse Fourier transform, and other possible implementations are not excluded. Exemplarily, the IFFT may also be an inverse discrete Fourier transform (IDFT).

如此，可以将待发送数据经过频域资源映射、IFFT得到时域数据，将时域数据经滤波以降低OOB，实现待发送数据的低OOB传输。In this way, the data to be transmitted can be obtained by time domain data mapping through frequency domain resource mapping and IFFT, and the time domain data can be filtered to reduce OOB, and low OOB transmission of the data to be transmitted can be realized.

在本申请实施例中，频域资源映射以及滤波的顺序可以如图4a所示，也可以先滤波，再通过相位旋转操作等效调整调制数据映射的频域资源位置，不予限制。例如，图4c为本申请实施例提供的再一种数据传输方法原理框图，如图4c所示，该发送数据的过程包括：将时域符号l′上传输的调制数据d _l′经过N次重复后得到长度为N的数据

In the embodiment of the present application, the order of frequency domain resource mapping and filtering may be as shown in FIG. 4a, or filtering may be performed first, and then the frequency domain resource position of the modulation data mapping is adjusted by phase rotation operation equivalently, without limitation. For example, FIG. 4c is a schematic block diagram of another data transmission method according to an embodiment of the present application. As shown in FIG. 4c, the process of sending data includes: passing the modulation data d _{l ′} transmitted on the time domain symbol _{l ′} through N times. Repeat to get data of length N

其中，重复、相位旋转等操作可参照图3对应的实施例中所述，不再赘述。如此，可以将待发送数据经过重复操作映射到时域符号上，将时域符号上的数据经过滤波降低数据的OOB，并将滤波后的数据经过相位旋转映射到相应的频域资源位置进行发送。For operations such as repetition and phase rotation, reference may be made to the embodiment corresponding to FIG. 3, and details are not described herein again. In this way, the data to be transmitted can be mapped to time-domain symbols through repeated operations, the data on the time-domain symbols can be filtered to reduce the OOB of the data, and the filtered data can be mapped to the corresponding frequency-domain resource locations for transmission by phase rotation. .

图4a～图4c可以适用于各种场景，如：可以适用于调制数据为BPSK调制数据或者Pi/2-BPSK调制数据或者QPSK调制数据或者Pi/4-QPSK调制数据的场景。尤其是调制数据d _l′为Pi/2-BPSK调制数据或Pi/4-QPSK调制数据时，相邻时域符号上传输的调制数据间具有相位差，将该调制数据应用于本申请实施例提供的方法时，在进行滤波操作时可以减小了同向相加的概率，因此可以保证所发送的数据s _l,0的PAPR性能较好。 4a to 4c may be applicable to various scenarios, for example, it may be applicable to a scenario where the modulation data is BPSK modulation data or Pi / 2-BPSK modulation data or QPSK modulation data or Pi / 4-QPSK modulation data. Especially when the modulation data d _{l ′} is Pi / 2-BPSK modulation data or Pi / 4-QPSK modulation data, there is a phase difference between the modulation data transmitted on adjacent time-domain symbols, and the modulation data is applied to the embodiments of the present application. When the method is provided, the probability of adding in the same direction can be reduced when performing the filtering operation, so the PAPR performance of the transmitted data s _{l, 0} can be guaranteed to be better.

由上可知，调制数据d _l′为Pi/2-BPSK调制数据或Pi/4-QPSK调制数据可以保证发送的数据具有良好的PAPR性能。因此，为了使发送数据具有良好的PAPR性能，可选地，当调制数据d _l′为BPSK调制数据时，可以对BPSK调制数据进行调制数据相位旋转，得到Pi/2-BPSK调制数据。当调制数据d _l′为QPSK调制数据时，可以对QPSK调制数据进行调制数据相位旋转，得到Pi/4-QPSK调制数据。对调制数据相位旋转后的Pi/2-BPSK调制数或者Pi/4-QPSK调制数据执行重复、相位旋转、滤波得到发送数据s _l,0；或者，对调制数据相位旋转后的Pi/2-BPSK调制数或者Pi/4-QPSK调制数据执行重复、滤波、相位旋转得到发送数据s _l,0；或者，对调制数据相位旋转后的Pi/2-BPSK调制数或者Pi/4-QPSK调制数据执行频域资源映射、IFFT、滤波得到发送数据s _l,0。具体的，该实现过程可参照图4d～图4f所示。 It can be known from the above that the modulation data d _{l ′} is Pi / 2-BPSK modulation data or Pi / 4-QPSK modulation data, which can ensure that the transmitted data has good PAPR performance. Therefore, in order to make the transmitted data have good PAPR performance, optionally, when the modulation data d _{l ′} is BPSK modulation data, the BPSK modulation data may be subjected to phase rotation of the modulation data to obtain Pi / 2-BPSK modulation data. When the modulation data d _{l ′} is QPSK modulation data, the QPSK modulation data may be subjected to phase rotation of the modulation data to obtain Pi / 4-QPSK modulation data. Perform repetition, phase rotation, and filtering on the Pi / 2-BPSK modulation number or Pi / 4-QPSK modulation data after phase rotation of the modulation data to obtain transmission data s _{l, 0} ; or, Pi / 2- after phase rotation of the modulation data BPSK modulation number or Pi / 4-QPSK modulation data is repeated, filtered, and phase rotated to obtain transmission data s _{l, 0} ; or Pi / 2-BPSK modulation number or Pi / 4-QPSK modulation data after phase rotation of the modulation data Perform frequency domain resource mapping, IFFT, and filtering to obtain the transmitted data s _{l, 0} . Specifically, this implementation process can be referred to FIGS. 4d to 4f.

在实际应用中，通信装置(如：终端设备或网络设备)在发送数据时可以经过功率放大器将数据信号放大后发送出去。由于不同通信装置的功率放大器(power amplifier，PA)的性能是不同的，在通信装置的PA的输入和输出之间的线性关系没有那么良好的情况下，通信装置发送的数据的PAPR越高，数据经过PA时受到的扭曲越严重，对发送的数据的OOB性能影响越大。因此，为了确保经过PA后的数据的低OOB性能，本申请实施例发送的数据还可以具有低PAPR性能。为了实现发送数据的低PAPR性能，图3所示方案还可以包括：In practical applications, a communication device (such as a terminal device or a network device) can transmit a data signal after being amplified by a power amplifier when transmitting data. Because the performance of power amplifiers (PAs) of different communication devices is different, when the linear relationship between the input and output of the PA of the communication device is not so good, the PAPR of the data sent by the communication device is higher, The more severe the distortion of the data as it passes through the PA, the greater the impact on the OOB performance of the transmitted data. Therefore, in order to ensure the low OOB performance of the data after PA, the data sent in the embodiments of the present application may also have low PAPR performance. In order to achieve low PAPR performance of the transmitted data, the solution shown in FIG. 3 may further include:

如此，可以将多路数据合并得到时域符号发送的数据。由于第m路对应的调制数据和滤波器系数分别由第0路对应的调制数据和滤波器系数生成，多路数据合并后第m路对应的时域数据可以压低第0路对应的时域数据的较高峰值点，提高第0路对应的时域数据的较低峰值点，使合并后的时域数据的各个数据点的幅度大小的波动趋于平稳，所以，多路数据合并后得到的数据具有低PAPR的性能。需要说明的是，本申请实施例中，M值越大，合并后得到的数据的PAPR可以越低，即合并的数据的路数越多，合并后得到的数据的PAPR可以越低。In this way, multiple channels of data can be combined to obtain data sent by time-domain symbols. Since the modulation data and filter coefficients corresponding to the m-th channel are generated by the modulation data and filter coefficients corresponding to the 0-th channel, the time-domain data corresponding to the m-th channel after the multi-channel data combination can be used to lower the time-domain data corresponding to the 0-th channel. The higher peak point of the channel is raised to the lower peak point of the time domain data corresponding to channel 0, so that the fluctuation of the amplitude of each data point of the merged time domain data is stabilized. The data has low PAPR performance. It should be noted that, in the embodiment of the present application, the larger the M value, the lower the PAPR of the data obtained after merging, that is, the more the number of ways of the merged data, the lower the PAPR of the data obtained after the merging.

例如，如图5所示，为多路数据合并得到的数据的PAPR示意图，其中，图5中的纵坐标轴表示互补累计分布函数(complementary cumulative distribution function，CCDF)，横坐标轴表示PAPR，①对应于采用Pi/2-BPSK调制，将生成的一路数据作为发送数据； ②对应于采用Pi/2-BPSK调制，将2路数据合并得到发送数据；③对应于采用Pi/4-QPSK调制，将生成的一路数据作为发送数据；④对应于采用Pi/4-QPSK调制，将3路数据合并得到发送数据。从图5中可以发现，采用Pi/2-BPSK调制时，将2路数据合并得到的发送数据的PAPR相比将一路数据作为发送数据的PAPR有1dB的增益；采用Pi/4-QPSK调制时，将3路数据合并得到的发送数据的PAPR相比将一路数据作为发送数据的PAPR有2dB的增益。For example, as shown in FIG. 5, it is a schematic diagram of the PAPR of the data obtained by merging multiple channels of data. In FIG. 5, the vertical axis represents the complementary cumulative distribution function (CCDF), and the horizontal axis represents PAPR. Corresponding to the use of Pi / 2-BPSK modulation, using the generated data as transmission data; ② Corresponding to using Pi / 2-BPSK modulation, combining the two channels of data to obtain the transmission data; ③ Corresponding to using Pi / 4-QPSK modulation, Take the generated data as transmission data; ④ Corresponding to the Pi / 4-QPSK modulation, combine the three data to obtain the transmission data. It can be found from Figure 5 that when using Pi / 2-BPSK modulation, the PAPR of the transmitted data obtained by combining the two channels of data has a gain of 1dB compared to the PAPR that uses one channel of data as the transmitting data; when using Pi / 4-QPSK modulation The PAPR of the transmitted data obtained by combining the three channels of data has a gain of 2 dB compared to the PAPR that uses one channel of data as the transmitted data.

下面结合图6～图13，以将4路数据合并处理得到发送数据为例，对上述方案进行说明。需要说明的是，除4路之外的其他多路数据合并处理得到发送数据的过程可参照图6～图13所述。The above solution will be described below with reference to FIGS. 6 to 13 by taking as an example the combined data of the four channels to obtain the transmitted data. It should be noted that, for a process of combining multiple channels of data other than four to obtain transmission data, reference may be made to FIG. 6 to FIG. 13.

需要说明的是，上述每路数据滤波时采用的k ₂、k ₁可以不同，也可以相同，不予限制。每路数据在滤波时k ₂到k ₁的取值范围与本路的滤波器系数的长度有关，如：第1路数据在滤波时k ₂-k ₁等于第1路滤波器系数C ₁的长度L ₁-1。 It should be noted that k ₂ and k ₁ used in the above-mentioned data filtering may be different or the same, and are not limited. The range of values of k ₂ to k ₁ for each channel of data during filtering is related to the length of the filter coefficient of this channel. For example, when the data of channel ₁ is filtered, k ₂ -k ₁ is equal to that of filter coefficient C ₁ of channel ₁ . Length L ₁ -1.

其中，图6中的重复、相位旋转和滤波的具体实现过程可参照图4a中所示，不再赘述。The specific implementation process of the repetition, phase rotation, and filtering in FIG. 6 can be referred to that shown in FIG. 4a and will not be described again.

图9中第1路至第3路滤波后的输出数据以及合并处理的输出数据也可以采用连续的表示方式来表示，具体参考图6中的实现，这里不在赘述。The filtered output data of the first to third channels in FIG. 9 and the output data of the merging process may also be expressed in a continuous manner. For details, refer to the implementation in FIG. 6, and details are not described herein.

在图9所示方法中，可以将多路数据经过重复、滤波后进行相加合并，将相加合并后的数据经过相位旋转发送出去。每路数据在处理过程中可以不添加CP，每个时域符号的长度均为N，当采用本申请实施例提供的滤波方式对每路数据进行滤波操作时，可以将k2-k1+1个时域符号的第n个数据点乘对应的滤波器系数后相加合并得到该路待发送的数据中的第n个数据，即该路待发送的数据中的第n个数据与其他时域符号的第n个数据相关，降低数据的OOB。同时，将多路数据进行合并处理可以压低数据的较高峰值点，提高数据的较低峰值点，使数据的各个点的峰值区域平稳，保证数据的低PAPR性能。In the method shown in FIG. 9, multiple channels of data may be repeated and filtered for addition and combination, and the added and combined data may be sent through phase rotation. During the processing of each channel of data, no CP is added, and the length of each time-domain symbol is N. When filtering is performed on each channel of data using the filtering method provided in the embodiment of the present application, k2-k1 + 1 The n-th data point of the time-domain symbol is multiplied by the corresponding filter coefficient, and then added and combined to obtain the n-th data in the data to be sent on the road, that is, the n-th data in the data to be sent on the road and other time domains The nth data of the symbol is correlated, reducing the OOB of the data. At the same time, combining multiple channels of data can reduce the higher peak points of the data, increase the lower peak points of the data, make the peak areas of the data points stable, and ensure the low PAPR performance of the data.

图6～图9可以适用于各种场景，如：可以适用于调制数据为BPSK调制数据或者 Pi/2-BPSK调制数据或者QPSK调制数据或者Pi/4-QPSK调制数据的场景。尤其是调制数据d _l′为Pi/2-BPSK调制数据或Pi/4-QPSK调制数据时，可以保证每路数据的PAPR性能较好，其原因如前所述，不再赘述。因此，为了使每路数据具有良好的PAPR性能，可选地，当调制数据为BPSK调制数据时，可以对BPSK调制数据进行调制数据相位旋转，得到Pi/2-BPSK调制数据。当调制数据为QPSK调制数据时，可以对QPSK调制数据进行调制数据相位旋转，得到Pi/4-QPSK调制数据。然后，再对调制数据相位旋转后的Pi/2-BPSK调制数据或者Pi/4-QPSK调制数据执行其他相应操作。具体的，如图10～图13所示。 6 to 9 may be applicable to various scenarios, for example, it may be applicable to a scenario where the modulation data is BPSK modulation data or Pi / 2-BPSK modulation data or QPSK modulation data or Pi / 4-QPSK modulation data. In particular, when the modulation data d _{l ′} is Pi / 2-BPSK modulation data or Pi / 4-QPSK modulation data, the PAPR performance of each channel of data can be guaranteed to be good. The reason is as described above and will not be described again. Therefore, in order to make each channel of data have good PAPR performance, optionally, when the modulation data is BPSK modulation data, the BPSK modulation data can be phase-rotated to obtain Pi / 2-BPSK modulation data. When the modulation data is QPSK modulation data, the QPSK modulation data can be subjected to phase rotation of the modulation data to obtain Pi / 4-QPSK modulation data. Then, perform other corresponding operations on the Pi / 2-BPSK modulated data or Pi / 4-QPSK modulated data after the phase of the modulated data is rotated. Specifically, as shown in FIG. 10 to FIG. 13.

For details, refer to the implementation in FIG. 6, and details are not described herein.

其中，在图6中，各路调制数据可以根据调制数据d _l'以及其他时域符号上传输的调制数据确定。示例性的，当调制数据d _l'为BPSK调制数据时，一种可能的设计中，将调制数据d _l′经过调制数据预处理得到调制数据d _l′,1为： Among them, in FIG. 6, each channel of modulation data may be determined according to the modulation data d _{l ′} and the modulation data transmitted on other time-domain symbols. Exemplarily, when the modulation data d _{l ′} is BPSK modulation data, in a possible design, the modulation data d _{l ′} is preprocessed by the modulation data to obtain the modulation data d _{l ′, 1} as:

d _l',1＝-d _l'×d _l'-1×d _l'-2×j d _{l ', 1} = -d _l' × d _l'-1 × d _l'-2 × j

d _l',2＝-d _l'×d _l'-2×d _l'-3×j d _{l ', 2} = -d _l' × d _l'-2 × d _l'-3 × j

d _l',3＝-d _l'×d _l'-1×d _l'-3 d _{l ', 3} = -d _l' × d _l'-1 × d _l'-3

其中，本申请实施例中，j为虚数单位。In the embodiment of the present application, j is an imaginary unit.

由上可知，调制数据d _l′,1、d _l′,2、d _l′,3可以是由时域符号l'上传输的调制数据d _l'以及时域符号l'前面若干个时域符号的调制数据确定的。需要说明的是，确定调制数据d _l′,1、d _l′,2、d _l′,3的方式包括但不限于上述可能的设计方式，例如根据上述两种实现方式等效得到的表达式也在本申请实施例的保护范围之内。 It can be known from the above that the modulation data d _{l ′, 1} , d _{l ′, 2} , d _{l ′, 3} may be the modulation data d _{l ′} transmitted on the time domain symbol l ′ and several time domains before the time domain symbol l ′. The modulation data of the symbol is determined. It should be noted that the manner of determining the modulation data d _{l ′, 1} , d _{l ′, 2} , d _{l ′, 3} includes, but is not limited to, the possible design manners described above, such as the expressions obtained equivalently according to the above two implementation manners It is also within the protection scope of the embodiments of the present application.

示例性的，当调制数据d _l'为QPSK调制数据时，各路数据对应的调制数据d _l′,1、d _l′,2可以由d _l'及d _l'-1确定。下面以确定第1路数据对应的调制数据、以及第2路数据对应的调制数据为例进行说明。例如，第1路数据的调制数据d _l′,1可以表示为d _l',1＝d _l'·β _l',1，第2路数据的调制数据d _l',2可以表示为d _l',2＝d _l'·β _l',2，其中，β _l',1、β _l',2由d _l'/d _l'-1确定，d _l'/d _l'-1有4种可能的取值。 Exemplarily, when the modulation data d _{l '} is QPSK modulation data, the modulation data d _{l', 1} and d _{l ', 2} corresponding to the data of each channel may be determined by d _l' and d _l'-1 . The following describes the modulation data corresponding to the first channel data and the modulation data corresponding to the second channel data as an example for description. For example, the modulation data d _{l ′, 1 of the first} data can be expressed as d _{l ', 1} = d _l' · β _{l ', 1} , and the modulation data d _{l', 2 of the second} data can be expressed as d _{l ', 2} = d _l' · β _{l ', 2} , where β _{l', 1} and β _{l ', 2 are} determined by d _l' / d _l'-1 , and d _{l '} / d _l'-1 has 4 Possible values.

一种可能的设计中，β _l',1、β _l',2与d _l'/d _l'-1间存在对应关系，该对应关系可以是预配置的，也可以是由网络设备通过信令为终端设备配置的。如表2所示，为β _l',1、β _l',2与d _l'/d _l'-1间的对应关系表，可以通过表1确定与d _l'/d _l'-1的取值对应的β _l',1与β _l',2，根据确定出的β _l',1与β _l',2确定d _l′,1、d _l′,2。 In a possible design, there is a corresponding relationship between β _{l ', 1} , β _{l', 2} and d _{l '} / d _l'-1 , and the corresponding relationship may be pre-configured or may be transmitted by a network device through a signal. The command is configured for the terminal device. As shown in Table 2 for _{_{β l ', 1, β l}} ', 2 and d _{l '/} d correspondence table between _l'-1, d _l may be determined from Table _{_1'} / d _l'-1 of The values corresponding to β _{l ', 1} and β _{l', 2 are} determined according to the determined β _{l ', 1} and β _{l', 2, and} d _{l ′, 1} and d _{l ′, 2 are determined} .

其中，图10中确定滤波器系数的过程可参照图6中相应的描述，如：当调制数据d _l'为QPSK调制数据时，第1路滤波器系数C ₁中的第n个值为： The process for determining the filter coefficients in FIG. 10 can be referred to the corresponding description in FIG. 6. For example, when the modulation data d _{l ′} is QPSK modulation data, the n-th value of the first filter coefficient C ₁ is:

这两个公式的计算结果比较接近，当调制数据d _l'为QPSK调制数据时，第1路数据、第2路数据的滤波器系数C ₁、C ₂可以近似为同一滤波器系数C ₁，其中，C ₁中的第n个值可以为： in case

versus

The calculation results of these two formulas are relatively close. When the modulation data d _{l '} is QPSK modulation data, the filter coefficients C ₁ and C _{2 of the} first channel data and the second channel data can be approximated to the same filter coefficient C ₁ , Among them, the nth value in C ₁ can be:

因第1路数据、第2路数据的滤波器系数C ₁、C ₂可以近似为同一滤波器系数C ₁，所以，在本申请实施例中，为了降低运算复杂度，可以将第1路、第2路合并为一路调制数据，对合并后的调制数据进行重复、相位旋转、滤波等操作，如此，将原有的4路数据减少为3路数据，降低了计算复杂度。示例性的，可以按照下述公式将第1路的调制数据d _l′,1、第2路的调制数据d _l′,2合并为一路数据的调制数据d _l′,1： Because the filter coefficients C ₁ and C _{2 of the} data of the first channel and the data of the second channel can be approximated by the same filter coefficient C ₁ , in the embodiment of the present application, in order to reduce the computational complexity, the The second channel is combined into one channel of modulation data, and operations such as repetition, phase rotation, and filtering are performed on the combined modulation data. In this way, the original four channels of data are reduced to three channels of data, which reduces the computational complexity. For example, the modulation data d _{l ′, 1} of the first channel and the modulation data d _{l ′, 2 of} the second channel may be combined into modulation data d _{l ′, 1 of} one channel according to the following formula:

其中，||表示取模运算。Among them, || represents the modulo operation.

During the processing of each channel of data, no CP is added, and the length of each time-domain symbol is N. When filtering is performed on each channel of data using the filtering method provided in the embodiment of the present application, k2-k1 + 1 The n-th data point of the time-domain symbol is multiplied by the corresponding filter coefficient, and then added and combined to obtain the n-th data in the data to be sent on the road, that is, the n-th data in the data to be sent on the road and other time domain The nth data of the symbol is correlated, reducing the OOB of the data. At the same time, combining multiple channels of data can reduce the higher peak points of the data, increase the lower peak points of the data, make the peak areas of the data points stable, and ensure the low PAPR performance of the data.
