技术领域technical field

本发明实施例涉及无线通信技术领域，尤其涉及一种信号传输方法和通信设备。Embodiments of the present invention relate to the field of wireless communication technologies, and in particular, to a signal transmission method and a communication device.

背景技术Background technique

旁链路(sidelink)业务的工作频段可能与其他网络的工作频段或者其他业务的工作频段存在重叠，此时sidelink业务的同步信号时频位置与其他网络或者其他业务的同步信号时频位置可能出现重叠，从而导致用户可能会选择错误的同步信号，导致无法快速甚至正常地进行sidelink业务。The working frequency band of the sidelink service may overlap with the working frequency band of other networks or the working frequency band of other services. At this time, the time-frequency position of the synchronization signal of the sidelink service and the time-frequency position of the synchronization signal of other networks or other services may appear. Overlapping, so that users may choose the wrong synchronization signal, resulting in the inability to conduct sidelink services quickly or even normally.

在非授权频谱辅助接入(Licensed-Assisted Access，简称LAA)中，由于非授权频段是多种技术共享，在发送信息之前，发送节点(网络侧设备或者终端)需要做空闲信道评估((extended)clear channel assess，简称CCA/eCCA，)侦听信道，即进行能量检测(energy detection，简称ED)，当能量低于一定门限时，信道被判断为空时，方可开始传输。每次侦听信道并判断为空之后，终端发送信号的持续时间需要小于一个最大信道占用时长(maximum channel occupancy time，简称MCOT)。也就是说，非授权频段上，多个发送方需要在竞争成功后才能获取资源并用于发送信号，因此实际上发送方可以获得的资源是不确定的，同理，接收方在搜索同步信号的时候，由于可能没有相关先验信息，因此因为搜索时间过长导致在MCOT时间内无法搜到基站发送的同步信号从而导致接收失败。In Licensed-Assisted Access (LAA), since the unlicensed frequency band is shared by multiple technologies, the sending node (network-side device or terminal) needs to perform an idle channel assessment (extended channel) before sending information. )clear channel assess, CCA/eCCA for short,) Listening to the channel, that is, performing energy detection (ED), when the energy is lower than a certain threshold and the channel is judged to be empty, transmission can be started. After each listening to the channel and judging that it is empty, the duration of the signal sent by the terminal needs to be less than a maximum channel occupancy time (maximum channel occupancy time, MCOT for short). That is to say, on the unlicensed frequency band, multiple senders need to obtain resources and use them to send signals after successful competition. Therefore, the resources that the sender can actually obtain are uncertain. Similarly, the receiver is searching for the synchronization signal. When there is no relevant prior information, the synchronization signal sent by the base station cannot be found within the MCOT time because the search time is too long, resulting in a reception failure.

下面首先对NR网络的工作频段相关内容进行简单说明。The following briefly describes the content related to the working frequency band of the NR network.

1、NR网络的工作频段1. Working frequency band of NR network

NR网络定义的部分工作频段以及其频域范围如下：Some of the working frequency bands defined by the NR network and their frequency domain ranges are as follows:

表1:在频率范围FR1中的NR工作频段(NR operating bands in FR1)Table 1: NR operating bands in FR1

2、NR网络引入了大带宽，在高频段上，带宽可以达到400MHz甚至1GHz。2. The NR network introduces a large bandwidth. In the high frequency band, the bandwidth can reach 400MHz or even 1GHz.

3、同步栅格(sync raster)3. Sync raster

NR网络为0-100GHz定义了同步栅格，工作频带上的同步信号块(SS Block简称SSB，也可以称为同步信号/物理广播信号块，SS/PBCH block)的频率位置是SS_REF，对应全局同步栅格号(GSCN)。基站可以在同步栅格上发送同步信号块。不同频域范围内GSCN的位置和计算如下表：The NR network defines a synchronization grid for 0-100GHz. The frequency position of the synchronization signal block (SS Block for short, SSB, also known as the synchronization signal/physical broadcast signal block, SS/PBCH block) on the working frequency band is SS_REF , corresponding to Global Synchronized Grid Number (GSCN). The base station may transmit synchronization signal blocks on the synchronization grid. The location and calculation of GSCN in different frequency domain ranges are as follows:

表2：全局同步栅格的GSCN的参数(GSCN parameters for the global frequencyraster)Table 2: GSCN parameters for the global frequencyraster

例如，GSCN＝2的时候，可以推出N＝1M＝1，从而对应的频域位置为1250kHz。For example, when GSCN=2, it can be deduced that N=1M=1, so the corresponding frequency domain position is 1250kHz.

根据NR在Rel-15的频域规划，根据不同的子载波间隔(subcarrier spacing，简称SCS)，分别为不同的工作频段定义了可支持的信道带宽，下表是band n1的信道带宽相关信息。例如对于band n1，当传输的数据/控制信号的SCS是15kHz时，在该band上的最小信道带宽为5MHz.According to the frequency domain planning of NR in Rel-15, according to different subcarrier spacing (SCS for short), the supported channel bandwidth is defined for different working frequency bands. The following table shows the channel bandwidth related information of band n1. For example, for band n1, when the SCS of the transmitted data/control signal is 15kHz, the minimum channel bandwidth on this band is 5MHz.

表3：NR工作频段的信道带宽(Channel bandwidths for each NR band)Table 3: Channel bandwidths for each NR band

NR中为不同的band定义了GSCN的范围和stepsize，stepsize为属于该band且相邻的同步栅格的GSCN的步长(即GSCN的差值)。例如n41的GSCN范围为6246-6714，stepsize为3，n41范围内的GSCN为6246，6249，……，6714。In NR, the range and stepsize of GSCN are defined for different bands, and stepsize is the step size of the GSCN of the adjacent synchronization grids belonging to the band (ie, the difference of GSCN). For example, the GSCN range of n41 is 6246-6714, the stepsize is 3, and the GSCN in the range of n41 is 6246, 6249, ..., 6714.

需要注意的是，不同的band之间频域可能存在重叠，例如band n38和n41.从下表可以看出，这两个频段虽然存在重叠但是GSCN的stepsize不同。It should be noted that there may be overlap in the frequency domain between different bands, such as bands n38 and n41. It can be seen from the table below that although these two bands overlap, the stepsize of GSCN is different.

表4:Applicable SS raster entries per operating bandTable 4: Applicable SS raster entries per operating band

4、信道栅格(channel raster)4. Channel raster

NR中定义了信道栅格，基站可以在信道栅格上部署信道。信道栅格可能为100kHz,15kHz,30kHz,60kHz,120kHz。The channel grid is defined in NR, and the base station can deploy channels on the channel grid. The channel raster may be 100kHz, 15kHz, 30kHz, 60kHz, 120kHz.

例如下表，band n1上的信道栅格为100kHz，其上行的频域对应的新无线-绝对无线频域信道编号(New radio Absolute Radio Frequency Channel Number，简称NR-ARFCN)号范围为384000-396000，下行的频域对应的NR-ARFCN号范围为422000-434000。一个NR-ARFCN号也可以用于指示一个频域位置。For example, in the following table, the channel grid on band n1 is 100kHz, and the new radio-absolute radio frequency channel number (NR-ARFCN) number corresponding to the upstream frequency domain is in the range of 384000-396000 , the NR-ARFCN number range corresponding to the downlink frequency domain is 422000-434000. An NR-ARFCN number can also be used to indicate a frequency domain location.

表5：Applicable NR-ARFCN per operating bandTable 5: Applicable NR-ARFCN per operating band

需要注意的是，不同的band之间频域可能存在重叠，例如band n38和n41.从下表可以看出，这两个频段虽然存在重叠但是NR-ARFCN的stepsize也不同。It should be noted that there may be overlap in the frequency domain between different bands, such as bands n38 and n41. It can be seen from the table below that although these two bands overlap, the stepsize of NR-ARFCN is also different.

表6:Applicable NR-ARFCN per operating bandTable 6: Applicable NR-ARFCN per operating band

为了避免某些工作频段(sidelink业务的工作频段或非授权频段等)的同步信号与NR网络的同步信号的频域位置出现重叠，导致无法快速确定用于发送或接收同步信号的频域位置的问题，请参考图1，本发明实施例提供一种信号传输方法，应用于通信设备，包括：In order to avoid the overlapping of the frequency domain position of the synchronization signal of some working frequency bands (the working frequency band of the sidelink service or the unlicensed frequency band, etc.) and the frequency domain position of the synchronization signal of the NR network, it is impossible to quickly determine the frequency domain position for sending or receiving the synchronization signal.

When the terminal is a transmitter of a synchronization signal When the terminal is connected to the terminal, the terminal can quickly determine the first synchronization grid for sending the synchronization signal, and send the synchronization signal on the determined first synchronization grid, so that the communication efficiency can be improved, and the physical connection with other types of services on the same frequency can be avoided.

Among them, V2X mainly includes Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Network (V2N) and at least one of Vehicle-to-Pedestrian (V2P for short).

下面对如何获得第一同步栅格的方法进行详细说明。The method of how to obtain the first synchronization grid will be described in detail below.

本发明实施例中，可以采用以下方式中的至少一项，获得所述第一同步栅格：In this embodiment of the present invention, at least one of the following manners may be used to obtain the first synchronization grid:

方式一：若所述预设工作频段与0-3000MHz范围存在重叠，重叠部分的所述预设工作频段的所述第一同步栅格的频域位置为：Offset1+stepsize1*N1*X+M1*50kHz，重叠部分的所述预设工作频段的所述第一同步栅格的第一GSCN为：3N1+(M1-3)/2，其中，Offset1为所述第一同步栅格的频域偏移值，stepsize1为相邻的所述第一同步栅格的第一GSCN的步长，X为相邻的所述第一同步栅格的频域单位差值，Offset1、N1和M1均为整数；Method 1: If the preset working frequency band overlaps with the 0-3000MHz range, the frequency domain position of the first synchronization grid of the preset working frequency band in the overlapping part is: Offset1+stepsize1*N1*X+M1 *50kHz, the first GSCN of the first synchronization grid of the preset working frequency band in the overlapping part is: 3N1+(M1-3)/2, where Offset1 is the frequency domain offset of the first synchronization grid Shift value, stepsize1 is the step size of the first GSCN of the adjacent first synchronization grid, X is the frequency domain unit difference of the adjacent first synchronization grid, Offset1, N1 and M1 are all integers ;

可以看出，方式一中，与NR网络的0-3000MHz范围的工作频段的频域位置的计算公式(请参考表2)相比，增加了Offset1和stepsize1，并且相邻的同步栅格的频域单位差值替换为X，X不限于1200KHz。It can be seen that, in the first method, compared with the calculation formula of the frequency domain position of the working frequency band in the 0-3000MHz range of the NR network (please refer to Table 2), Offset1 and stepsize1 are added, and the frequency of the adjacent synchronization grid is The domain unit difference is replaced by X, which is not limited to 1200KHz.

方式二：若所述预设工作频段与3000-24250MHz范围存在重叠，重叠部分的所述预设工作频段的所述第一同步栅格的频域位置为：Offset2+R1+stepsize2*N2*Y，重叠部分的所述预设工作频段的所述第一同步栅格的第一GSCN为：GSCN_offset1+N2，其中，Offset2为所述第一同步栅格的频域偏移值，R1为3000-24250MHz范围的频域最低的所述第一同步栅格的频域位置，stepsize2为相邻的所述第一同步栅格的第一GSCN的步长，Y为相邻的所述第一同步栅格的频域单位差值，GSCN_offset1由0-3000MHz范围内所述第一同步栅格的第一GSCN的最大值确定，GSCN_offset1、Offset2和N2均为整数；Method 2: If the preset working frequency band overlaps with the 3000-24250MHz range, the frequency domain position of the first synchronization grid of the preset working frequency band in the overlapping part is: Offset2+R1+stepsize2*N2*Y , the first GSCN of the first synchronization grid of the preset working frequency band in the overlapping part is: GSCN_offset1+N2, where Offset2 is the frequency domain offset value of the first synchronization grid, and R1 is 3000- The frequency domain position of the first synchronization grid with the lowest frequency domain in the range of 24250MHz, stepsize2 is the step size of the first GSCN of the adjacent first synchronization grid, Y is the adjacent first synchronization grid The frequency domain unit difference value of the grid, GSCN_offset1 is determined by the maximum value of the first GSCN of the first synchronization grid in the range of 0-3000MHz, and GSCN_offset1, Offset2 and N2 are all integers;

R1例如可以为3000MHz。R1 may be, for example, 3000 MHz.

GSCN_offset1由0-3000MHz范围内所述第一同步栅格的第一GSCN的最大值确定，是指GSCN_offset1等于0-3000MHz范围内所述第一同步栅格的第一GSCN的最大值，或者，等于0-3000MHz范围内所述第一同步栅格的第一GSCN的最大值+1。GSCN_offset1 is determined by the maximum value of the first GSCN of the first synchronization grid in the range of 0-3000MHz, which means that GSCN_offset1 is equal to the maximum value of the first GSCN of the first synchronization grid in the range of 0-3000MHz, or equal to The maximum value of the first GSCN of the first synchronization grid in the range of 0-3000MHz+1.
