具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1是根据一示例性实施例示出的一种信号传输方法的示意流程图。如图1所示，该方法包括以下步骤。
步骤S1，确定目标设备；
步骤S2，向所述目标设备传输5G信号，所述5G信号中包括同步块，所述同步块用于承载物理广播信道、主同步信号、辅同步信号以及解调参考信号；
其中，所述解调参考信号和所述辅同步信号用于作为所述物理广播信道的解调结果的参考。
在一个实施例中，目标设备可以是5G基站，也可以是用户设备。在目标设备为5G基站的情况下，该方法可以应用于用户设备，在目标设备为用户设备的额情况下，该方法可以应用于5G基站。
在一个实施例中，通过在同步块中进一步设置解调参考信号，可以将辅助同步信号和解调参考信号两者作为物理广播信道的解调结果的参考，也即可以根据辅助同步信号和解调参考信号对物理广播信道的解调结果的相位进行调整。
例如在传输设备向目标设备传输同步块的场景中，传输设备需要先对同步块进行调制，然后传输至目标设备，由目标设备进行解调，但是由于传输过程会受到多普勒效应等因素的影响，使得目标设备接收到的同步块与传输设备传输的同步块存在相位差，从而导致对同步块的解调结果(主要是物理广播信道)与调制前的同步块(主要是物理广播信道)存在相位差。
根据辅同步信号，可以对同步块的解调结果的相位进行调整，在一定程度上消除上述相位差，在此基础上根据解调参考信号对同步块的解调结果的相位进行调整，则可以进一步消除上述相位差，从而保证调整后的解调结果的相位与传输设备调制前的同步块的相位尽可能相同，极大程度上消除信号传输过程中因多普勒效应等因素对 同步块相位的影响。
在一个实施例中，可以先根据辅助同步信号对物理广播信道的调节结果的相位进行调整，然后根据解调参考信号对物理广播信道的调节结果的相位进行调整；也可以先根据解调参考信号对物理广播信道的调节结果的相位进行调整，然后根据辅助同步信号对物理广播信道的调节结果的相位进行调整；还可以同时根据辅助同步信号和解调参考信号对物理广播信道的调节结果的相位进行调整。上述三通调整方式，对于解调结果的相位的调整效果是相同的，可以根据需要选择调整。
可选地，所述解调参考信号包括第一部分信号和第二部分信号；
其中，所述第一部分信号和所述主同步信号频分复用，所述第二部分信号和所述辅同步信号频分复用。
在一个实施例中，同步块的带宽是预先设定的，而主同步信号和辅同步信号一方面需要在时域上设置在不同的符号(时域上的单位)中，另一方面主同步信号和辅同步信号的数据量又不会占用一个完整的带宽。因此可以将解调参考信号拆分为两部分，并将其中的第一部分信号和主同步信号频分复用，将其中的第二部分信号和辅同步信号频分复用。也即将第一部分信号和主同步信号设置在同一个符号中，通过主同步信号未占用的部分带宽传输第一部分信号；将第二部分信号和辅同步信号设置在同一个符号中，通过辅同步信号未占用的部分带宽传输第二部分信号，从而对保证带宽较高的利用率。
图2是根据一示例性实施例示出的一种同步块的示意图。如图2所示，所述同步块包括第一符号10、第二符号20、第三符号30和第四符号40；
其中，所述物理广播信道PBCH位于所述第一符号10和第二符号20，所述主同步信号PSS和所述第一部分信号DMRS1位于所述第三符号30，所述辅同步信号SSS和所述第二部分信号DMRS2位于所述第四符号40。
在一个实施例中，在第一部分信号和主同步信号频分复用，第二部分信号和辅同步信号频分复用的基础上，可以进一步按照图2所示的实施例设置物理广播信道PBCH、主同步信号PSS、辅同步信号SSS、第一部分信号DMRS1和第二部分信号DMRS2。如图2所示，可以将主同步信号PSS和第一部分信号DMRS1位于设置在同一个符号，也即第三符号30中，将辅同步信号SSS和第二部分信号DMRS2设置在同一个符号，也即第四符号40中。并且根据物理广播信道PBCH所承载内容的需要，需 要保证PBCH占用完整的带宽，并且至少设置在两个符号中，因此可以将PBCH信道设置在两个符号中，也即第一符号10和第二符号20中。
需要说明的是，图2和以下其他附图所示的实施例中，符号对应的标号并不对应符号在时域上的顺序，例如在图2所示的实施例中，各符号在时域上的顺序为从左到右或为从右到左。
图3是根据一示例性实施例示出的另一种同步块的示意图。
在一个实施例中，如图3所示，主同步信号PSS以及辅同步信号SSS占用的带宽并不限于图2所示位于带宽的同一位置，例如图3所示，主同步信号PSS可以位于带宽头，辅同步信号SSS可以位于带宽尾。
可选地，所述第一部分信号包括多个第一部分子信号，所述多个第一部分子信号分别与所述主同步信号频分复用；
所述第二部分信号包括多个第二部分子信号，所述多个第二部分子信号分别与所述辅同步信号频分复用。
图4是根据一示例性实施例示出的又一种同步块的示意图。
在一个实施例中，以图2所示实施例的场景为例，如图4所示，在图2所示实施例的基础上，第一部分信号DMRS1可以进一步包含多个第一部分子信号，例如两个，其中一个第一部分子信号dmrs1’位于带宽头，另一个第一部分子信号dmrs1”位于带宽尾。第二部分信号DMRS2可以进一步包含多个第二部分子信号，例如两个，其中一个第二部分子信号dmrs2’位于带宽头，另一个第二部分子信号dmrs2”位于带宽尾。并且在这种情况下，可以根据需要进一步调整各信号在带宽中的位置，只需保证第一部分子信号和主同步信号频分复用，以及第二部分子信号和辅同步信号频分复用即可。
图5是根据一示例性实施例示出的又一种同步块的示意图。如图5所示，所述第一符号10和所述第二符号20分别与所述第四符号40相邻。
在一个实施例中，同步块在传输过程中受到的影响，会涉及其中每个符号对应的内容，而相距越远的符号对应的内容受到影响的差异度越大，相应地，相距越近的符号对应的内容受到影响的差异度越小。
而第一符号和第二符号对应的内容为物理广播信道，若将第四符号设置的距离 第一符号或第二符号较远，那么第四符号中辅同步信号和解调参考信号与第一符号或第二符号中物理广播信道受到影响的差异度就较大，将辅同步信号和解调参考信号作为物理广播信道的解调结果的参考准确度就较低。
因此通过将第一符号10和第二符号20设置为与第四符号40相邻，可以保证第四符号40中辅同步信号SSS和第二部分信号DMRS2与第一符号10或第二符号20中物理广播信道PBCH受到影响的差异度较小，进而保证将辅同步信号SSS和第二部分信号DMRS2作为物理广播信道PBCH的解调结果的参考具有较高的准确度。
图6是根据一示例性实施例示出的又一种同步块的示意图。
可选地，所述第二符号20与所述第三符号30相邻，且所述第三符号30在所述同步块尾(如图6所示)；或
所述第二符号20与所述第三符号30相邻，且所述第三符号30在所述同步块头(如图5所示)。
在一个实施例中，第一符号10和所述第二符号20分别与第四符号40相邻的情况可以包括图5和图6两种情况，可以根据需要进行设置。
图7是根据一示例性实施例示出的又一种同步块的示意图。图8是根据一示例性实施例示出的又一种同步块的示意图。图9是根据一示例性实施例示出的又一种同步块的示意图。
可选地，所述第一符号10和所述第四符号40分别与所述第三符号30相邻，且所述第一符号10在所述同步块头，所述第二符号20在所述同步块尾(如图2所示)；或
所述第一符号10和所述第三符号30分别与所述第四符号40相邻，且所述第一符号10在所述同步块头，所述第二符号20在所述同步块尾(如图7所示)；或
所述第一符号10和所述第二符号20分别与所述第三符号30相邻，且所述第一符号10在所述同步块头，所述第四符号40在所述同步块尾(如图8所示)；或
所述第一符号10和所述第二符号20分别与所述第三符号30相邻，且所述第四符号40在所述同步块头，所述第一符号10在所述同步块尾(如图9所示)。
在一个实施例中，同步块除了图5和图6所示的第一符号10和所述第二符号20分别与第四符号40相邻的情况，还可以包括图2、图7、图8和图9所示的情况， 可以根据需要进行设置。
图10是根据一示例性实施例示出的又一种同步块的示意图。图11是根据一示例性实施例示出的又一种同步块的示意图。所述同步块还用于承载5G物理下行控制信道NR-PDCCH(3GPP的5G New Radio规范标准中的Physical Downlink Control Channel)；
其中，所述5G物理下行控制信道NR-PDCCH位于所述第三符号30(如图10所示)，与所述主同步信号和所述第一部分信号频分复用，或位于所述第四符号40(如图11所示)，与所述辅同步信号和所述第二部分信号频分复用。
在一个实施例中，同步块除了可以承载物理广播信道PBCH、主同步信号PSS、辅同步信号SSS和解调参考信号DMRS，还可以承载5G物理下行控制信道NR-PDCCH，其中，5G物理下行控制信道NR-PDCCH可以用于承载Paging的indication(寻呼的指示)或者其他信息。由于5G物理下行控制信道NR-PDCCH可以承载多样化的信息，因此通过设置同步块额外承载5G物理下行控制信道NR-PDCCH，便于通过同步块向目标设备传输多样化的信息。
图12是根据一示例性实施例示出的又一种同步块的示意图。图13是根据一示例性实施例示出的又一种同步块的示意图。如图12和图13所示，所述同步块还用于承载5G物理下行控制信道，所述5G物理下行控制信道包括第一子信道NR-PDCCH1和第二子信道NR-PDCCH2；
其中，所述第一子信道NR-PDCCH1位于所述第三符号30，与所述主同步信号和所述第一部分信号频分复用，所述第二子信道NR-PDCCH2位于所述第四符号40，与所述辅同步信号和所述第二部分信号频分复用。
在一个实施例中，可以根据5G物理下行控制信道NR-PDCCH所承载的信号需要占用的带宽来调整其在同步块中占用的带宽和符号。
例如在5G物理下行控制信道NR-PDCCH所承载的信号需要占用的带宽较小的情况下，可以根据图10和图11所示的实施例在同步块中设置5G物理下行控制信道NR-PDCCH，也即仅占用对应一个符号的带宽的一部分。
而在5G物理下行控制信道NR-PDCCH所承载的信号需要占用的带宽较大的情况下，则可以根据图12和图13所示的实施例，将5G物理下行控制信道NR-PDCCH划分为第一子信道NR-PDCCH1和第二子信道NR-PDCCH2两部分，并适当减少第一 部分信号DMRS1所占用的带宽，以将第一子信道NR-PDCCH1设置在第三符号30对应的带宽中，以及适当减少第二部分信号DMRS2所占用的带宽，以将第二子信道NR-PDCCH2设置在第四符号40对应的带宽中，从而保证占用尽量少的符号完成分配。
图14是根据一示例性实施例示出的又一种同步块的示意图。如图14所示，所述同步块还用于承载5G物理下行控制信道NR-PDCCH，所述同步块还包括第五符号50；
其中，所述5G物理下行控制信道位NR-PDCCH于所述第五符号50。
在一个实施例中，在图12和图13所示实施例的基础上，当5G物理下行控制信道位NR-PDCCH所承载的信号过多，无法通过适当减少解调参考信号DMRS所占用的带宽将5G物理下行控制信道NR-PDCCH设置在第三符号30或第四符号40中时，可以在同步块中进一步拓展出第五符号50，并将5G物理下行控制信道NR-PDCCH设置在第五符号50中，以保证5G物理下行控制信道NR-PDCCH能够顺利承载信息。
图15是根据一示例性实施例示出的又一种同步块的示意图。如图15所示，所述物理广播信道还位于所述第五符号50，与所述5G物理下行控制信道频分复用。
在一个实施例中，在同步块包含五个符号50的基础上，若物理广播信道所承载的信号也较多，第一符号10和第二符号20所对应的带宽已不足以传输时，可以将第一符号10和第二符号20所对应的带宽不足以传输的部分设置在第五符号50中，从而无需再在同步块中拓展额外的符号，从而保证占用尽量少的符号完成分配。
图16是根据一示例性实施例示出的又一种同步块的示意图。如图16所示，所述同步块还用于承载5G物理下行控制信道NR-PDCCH，所述同步块包括第一符号10、第二符号20、第三符号30和第四符号40；
其中，所述物理广播信道PBCH位于所述第一符号10和第二符号20，所述主同步信号和5G物理下行控制信道NR-PDCCH频分复用，且位于所述第三符号30，所述辅同步信号SSS和所述解调参考信号DMRS频分复用，且位于所述第四符号40。
在一个实施例中，在同步块承载5G物理下行控制信道NR-PDCCH的情况下，可以将主同步信号PSS和5G物理下行控制信道NR-PDCCH频分复用，设置在同一个符号中，也即第三符号30中，并将辅同步信号SSS和解调参考信号DMRS设置在同一符号中，也即第四符号40中。从而一方面保证占用尽量少的符号完成分配，另一方面保证用于作为物理广播信道PBCH的解调结果的参考的辅同步信号SSS和解调参考 信号DMRS，能够位于同一个符号，以便同时解调出来作为参考。
在一个实施例中，还可以将图16所示的实施例和图5至图9所示的实施例相结合，也即按照图5至图9所示的实施例调整各符号，并且以上各实施例中的第一符号和第二符号可以对调，在此不再赘述。
