同步信号块的配置信息的广播、接收方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及同步信号块的配置信息的广播方法、同步信号块的配置信息的接收方法、同步信号块的配置信息的广播装置、同步信号块的配置信息的接收装置、电子设备和计算机可读存储介质。
背景技术
在5G NR(New Radio，新空口)技术中，基站通过RMSI(Remaining minimum system information，其它非必要信息)发送配置信息来指示同步信号块(Synchronizing Signal Block，简称SSB)的发送情况。
然而在某些通信场景下，例如车联网(V2X)中直连链路(sidelink)通信的场景下，通信双方并不发送RSMI，这会影响上述配置信息的发送。

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是根据本公开的实施例示出一种同步信号块的配置信息的广播方法的示意流程图。本实施例所示的同步信号块的配置信息的广播方法可以适用于适用于直连链路通信中能够起到基站作用的设备，例如能够模仿基站通过波束发射信号的车辆，该车辆可以基于5G NR技术与其他车辆通信。
如图1所示，所述同步信号块的配置信息的广播方法可以包括以下步骤：
在步骤S11中，根据发送同步信号块的频段，确定所能发送的同步信号块的最大数量；
在步骤S12中，根据所述最大数量与第一预设数值的关系确定需要生成的配置信息的比特数，并生成包含所述比特数的配置信息，其中，所述配置信息用于指示在最大数量的同步信号块中需要发送的同步信号块，所述第一预设数值与所述物理直连广播信道所能发送的比特数正相关；
在步骤S13中，通过物理直连广播信道广播所述配置信息。
本实施可以适用在车联网场景中，在车联网场景中，车辆可以与其他车辆、车内设备、路边设备进行通信，以车辆和其他车辆通信为例，例如A车辆可以接收到基站发送的信号，而B车辆由于某些原因(例如处于基站覆盖范围以外)而不能接收到基站发送的信号，但是A车辆距离B车辆较近，可以接收到A车辆发送的信号，那么A车辆可以先与基站通信，接收基站发送的信息，然后模仿基站通过波束发射信号，使得B车辆可以接收到A车辆发射的信号，进而基于A车辆发射的信号获取到基站发 送的信息，A车辆和B车辆的通信并不通过基站，两者是基于直连链路进行的通信，在此通信过程中，A车辆充当基站，B车辆充当用户设备。本实施例所示的方法可以应用于A车辆。
由于通过直连链路通信并不发送RMSI，因此与基站和用户设备进行通信不同，本公开的实施例可以通过物理直连广播信道(Physical Sidelink Broadcast Channel，简称PSBCH)广播所述配置信息。
配置信息的比特数越多，可以表达的内容越准确，例如所能发送的同步信号块的最大数量为L(L可以等于4、8、64等数值)，也即最多能够发送的同步信号块的数量为L，但是其中可能存在某些同步信号块不需要发送的情况，那么当配置信息的比特数为L，通过配置信息可以精确地表示这L个同步信号块中每个同步信号块是否为需要发送的同步信号块。
考虑到物理直连广播信道所能发送内容的比特数较为有限，所能发送的比特数并不一定能够达到最多能够发送的同步信号块的数量L，那么就需要适当调整配置信息的比特数。
本实施可以根据发送同步信号块的频段，确定所能发送的同步信号块的最大数量L，随着频段的中心频率提高，通过该频段发送信号就越容易受到遮挡，因此就需要发送更多数量的同步信号块来克服遮挡带来的影响，因此频段的中心频率越高，L值越大，频段的中心频率越低，L值越小。然后根据最大数量与第一预设数值K的关系确定需要生成的配置信息的比特数。其中，所述第一预设数值与所述物理直连广播信道所能发送的比特数正相关，也即能够发送比特数较多的物理直连广播信道，第一预设数值较大，能够发送比特数较少的物理直连广播信道，第一预设数值较小。
例如可以选择物理直连广播信道所能发送的比特数的最大值作为第一预设数值，也可以选择比物理直连广播信道所能发送的比特数的最大值小的值作为第一预设数值，在这种情况下，第一预设数值可以是物理直连广播信道中能够用于发送配置信息的比特数的上限值，物理直连广播信道中的其他比特数则需要传输配置信息以外的内容。
以物理直连广播信道所能发送的比特数的最大值作为第一预设数值为例。如果所能发送的同步信号块的最大数量L小于或等于第一预设数值K，说明通过物理直连广播信道可以发送L个比特的配置信息，那么可以生成比特数为L的配置信息，以便 准确地表示L个同步信号块中每个同步信号块是否为需要发送的同步信号块。如果所能发送的同步信号块的最大数量L大于第一预设数值K，说明通过物理直连广播信道不足以发送L个比特的配置信息，那么生成的配置信息的比特数就需要小于L，以保证能够通过物理直连广播信道顺利地发送配置信息。
根据本公开的实施例，在直连链路通信的场景下，可以通过物理直连广播信道广播所述配置信息，并且可以根据所述最大数量与第一预设数值的关系确定需要生成的配置信息的比特数，并生成包含所述比特数的配置信息，以保证能够通过物理直连广播信道顺利地发送配置信息。
图2是根据本公开的实施例示出一种根据所述最大数量与第一预设数值的关系确定配置信息的比特数，并生成包含所述比特数的配置信息的示意流程图。如图2所示，所述根据所述最大数量与第一预设数值的关系确定配置信息的比特数，并生成包含所述比特数的配置信息包括：
在步骤S121中，确定所述最大数量是否大于第一预设数值；
在步骤S122中，若所述最大数量小于或等于第一预设数值，生成比特数为所述最大数量的配置信息，其中，所述配置信息中的每个比特分别表示一个同步信号块是否为需要发送的同步信号块。
在一个实施例中，以选择物理直连广播信道所能发送的比特数的最大值作为第一预设数值K为例，若所述最大数量L小于或等于第一预设数值K，说明通过物理直连广播信道可以发送最大数量L个比特的配置信息，那么可以生成比特数为L的配置信息，以便准确地表示L个同步信号块中每个同步信号块是否为需要发送的同步信号块。
图3是根据本公开的实施例示出另一种根据所述最大数量与第一预设数值的关系确定配置信息的比特数，并生成包含所述比特数的配置信息的示意流程图。如图3所示，最大数量的同步信号块包括n个同步信号块组，每个同步信号块组包括m个同步信号块，其中，m和n为正整数，所述根据所述最大数量与第一预设数值的关系确定配置信息的比特数，并生成包含所述比特数的配置信息包括：
在步骤S123中，确定所述最大数量是否大于第一预设数值；
在步骤S124中，若所述最大数量大于第一预设数值，生成比特数为n+m的配置信息，其中，所述n+m个比特中的n个比特用于指示n个同步信号块组中每个同步 信号块组是否为需要发送的同步信号块组，所述n+m个比特中的m个比特用于指示需要发送的同步信号块组中每个同步信号块是否为需要发送的同步信号块。
在一个实施例中，以选择物理直连广播信道所能发送的比特数的最大值作为第一预设数值为例，若所述最大数量L大于第一预设数值K，说明通过物理直连广播信道不足以发送L个比特的配置信息，那么生成的配置信息的比特数就需要小于L，以保证能够通过物理直连广播信道顺利地发送配置信息，其中，L＝m×n。
同时，还需要保证通过物理直连广播信道发送的配置信息能够准确地表达L个信号块中哪些信号块为需要发送的信号块，因此本实施例主要适用最大数量的同步信号块包括n个同步信号块组，每个同步信号块组包括m个同步信号块。当每组同步信号块中相同位置的同步信号块的发送情况相同，就可以通过n+m个比特的配置信息表达L个同步信号块中每个同步信号块是否为需要发送的同步信号块。
以L＝64，m＝8，n＝8为例，8个同步信号块组中的某些同步信号块组可以不发送，那么可以通过8个比特表示8个同步信号块组每个同步信号块组是否为需要发送的同步信号块组，例如第2个和第7个同步信号块组不发送，n个比特为10111101，m个比特则用于指示需要发送的同步信号块组中每个同步信号块是否为需要发送的同步信号块，例如每组同步信号块都是第3个和第4个同步信号块不需要发送，那么每个需要同步信号块组中同步信号块是否需要发送的情况可以通过m个比特表示，m个比特为11001111，据此，可以通过16个比特表达64个同步信号块的发送情况，减少了通过物理直连广播信道发送的配置信息的比特数。
图4是根据本公开的实施例示出又一种根据所述最大数量与第一预设数值的关系确定配置信息的比特数，并生成包含所述比特数的配置信息的示意流程图。如图4所示，最大数量的同步信号块包括n个同步信号块组，每个同步信号块组包括m个同步信号块，其中，m和n为正整数，所述根据所述最大数量与第一预设数值的关系确定配置信息的比特数，并生成包含所述比特数的配置信息包括：
在步骤S125中，确定所述最大数量是否大于第一预设数值；
在步骤S126中，若所述最大数量大于第一预设数值，确定所述配置信息所在的发送波束，生成比特数为(n-1)+(m-1)的配置信息，其中，所述(n-1)+(m-1)个比特中的(n-1)个比特用于指示所述发送波束对应的同步信号块所在的同步信号块组以外的(n-1)个同步信号块组中每个同步信号块组是否为需要发送的同步信号块组，所述 (n-1)+(m-1)个比特中的(m-1)个比特用于指示需要发送的同步信号块中所述发送波束对应的同步信号块以外的(m-1)个同步信号块中每个同步信号块是否为需要发送的同步信号块。
虽然基于图3所示的实施例，可以减少通过物理直连广播信道发送的配置信息的比特数，但是通过进一步考虑，由于充当基站的车辆可以确定发送配置信息的波束，也即配置信息所在的发送波束，并且充当用户设备的车辆可以确定接收配置信息的波束，也即配置信息所在的接收波束，因此，在发送配置信息时，可以在m个比特中省去一个比特，该比特即发送配置信息所在波束对应的目标同步信号块的发送情况，由于需要在该波束发送目标同步信号块，那么该比特必然为1，所以只需要发送其他m-1比特来表示目标同步信号块以外的同步信号块的是否需要发送即可。
进一步地，由于目标同步信号块被发送，那么目标同步信号块所在的目标同步信号块组也被发送，所以目标同步信号块组在n个比特中对应的比特也必然为1，从而可以在n个比特中也省去一个比特，只需要发送其他n-1比特来表示目标同步信号块组以外的同步信号块组的是否需要发送即可。
根据本实施例，可以在图3所示实施例的基础上进一步减少通过物理直连广播信道发送的配置信息的比特数，从而降低对物理直连广播信道的占用。
图5是根据本公开的实施例示出另一种同步信号块的配置信息的广播方法的示意流程图。如图5所示，所述方法还包括：
在步骤S14中，在通过物理直连广播信道广播所述配置信息之前，确定所述配置信息的比特数是否大于第二预设数值；
若所述配置信息的比特数大于第二预设数值，所述通过物理直连广播信道广播所述配置信息包括：
在步骤S131中，通过物理直连广播信道广播所述配置信息中第二预设数值比特的信息，通过其他信道传输所述配置信息中其他比特的信息。
在一个实施例中，第二预设数值可以是比物理直连广播信道所能发送的比特数的最大值小的值，第二预设数值可以是物理直连广播信道中能够用于发送配置信息的比特数的上限值，在这种情况下，物理直连广播信道中的其他比特数则需要传输配置信息以外的内容，若所述配置信息的比特数大于第二预设数值，那么仅通过物理直连广播信道并不足以发送配置信息，因此可以通过物理直连广播信道广播所述配置信息 中第二预设数值比特的信息，通过其他信道传输所述配置信息中其他比特的信息，确保配置信息能够顺利地发送。
可选地，所述同步信号块组中的同步信号块与波束一一对应。
可选地，所述同步信号块组中的多个同步信号块对应相同波束。
在一个实施例中，除了同步信号块与波束一一对应的情况，还存在多个同步信号块对应相同波束的情况，在这种情况下，由于一个波束可以发送多个同步信号块(并非同时发送，而是在不同时刻发送，同一时刻仍只能发送一个同步信号块)，配置信息中的比特数就与波束相关，也即需要根据所述最大数量对应的波束的数量与第一预设数值的关系确定需要生成的配置信息的比特数。
例如所能发送的同步信号块的最大数量L＝8，所能发送的波束数量B n＝4，也即每个波束能够发送两个同步信号块，那么配置信息的比特数就是基于B n来判断，判断方式与前述实施例相同，例如B n小于或等于K，生成比特数为B n的配置信息。
图6是根据本公开的实施例示出一种同步信号块的配置信息的接收方法的示意流程图。本实施例所示的同步信号块的配置信息的接收方法可以适用于适用于直连链路通信中能够起到用户设备作用的设备，例如与图1所示实施例中充当基站的车辆进行通信的车辆，该车辆可以基于5G NR技术接收图1所示实施例中充当基站的车辆广播的信息。
如图6所示，所述同步信号块的配置信息的接收方法可以包括以下步骤：
在步骤S21中，根据接收同步信号块的频段，确定所能接收的同步信号块的最大数量；
在步骤S22中，根据在所述频段中接收同步信号块的物理直连广播信道确定第一预设数值，其中，所述第一预设数值与所述物理直连广播信道所能发送的比特数正相关；
在步骤S23中，根据所述最大数量与第一预设数值的关系确定需要接收的配置信息的比特数，其中，所述配置信息用于指示在最大数量的同步信号块中需要接收的同步信号块；
在步骤S24中，通过物理直连广播信道接收所述配置信息；
在步骤S25中，根据所述比特数确定解析所述配置信息所依据的参数；
在步骤S26中，依据所述参数解析所述配置信息。
在一个实施例中，本实施例所示的方法可以应用于充当用户设备的车辆，例如与图1所示实施例相对应地，可以应用于B车辆。
由于接收配置信息的车辆可以确定接收配置信息的频段，从而可以确定接收的同步信号块的最大数量。还可以确定接收同步信号块的物理直连广播信道，并确定该物理直连广播信道能接收的同步信号块的最大数量L，进而根据在所述频段中接收同步信号块的物理直连广播信道确定第一预设数值K，进而根据所述最大数量L与第一预设数值K的关系确定需要接收的配置信息的比特数。
根据接收到的配置信息比特数，车辆确定解析所述配置信息的算法中的参数，进而根据确定参数的算法解析配置信息，并根据配置信息确定同步信号块的发送情况，以便接收同步信号块。
图7是根据本公开的实施例示出一种根据所述最大数量与第一预设数值的关系确定接收配置信息的比特数的示意流程图。如图7所示，所述根据所述最大数量与第一预设数值的关系确定接收配置信息的比特数包括：
在步骤S231中，确定所述最大数量是否大于第一预设数值；
在步骤S232中，若所述最大数量小于或等于第一预设数值，确定接收比特数为所述最大数量的配置信息，其中，所述配置信息中的每个比特分别表示一个同步信号块是否为需要接收的同步信号块。
在一个实施例中，与图2所示实施例相对应地，若所述最大数量L小于或等于第一预设数值K，说明通过物理直连广播信道可以接收最大数量L个比特的配置信息，也即充当基站的车辆通过物理直连广播信道可以发送最大数量L个比特的配置信息，那么可以确定接收比特数为L的配置信息。
图8是根据本公开的实施例示出另一种根据所述最大数量与第一预设数值的关系确定接收配置信息的比特数的示意流程图。如图8所示，最大数量的同步信号块包括n个同步信号块组，每个同步信号块组包括m个同步信号块，其中，m和n为正整数，所述根据所述最大数量与第一预设数值的关系确定接收配置信息的比特数包括：
在步骤S233中，确定所述最大数量是否大于第一预设数值；
在步骤S234中，若所述最大数量大于第一预设数值，确定接收比特数为n+m 的配置信息，其中，所述n+m个比特中的n个比特用于指示n个同步信号块组中每个同步信号块组是否为需要接收的同步信号块组，所述n+m个比特中的m个比特用于指示需要接收的同步信号块组中每个同步信号块是否为需要接收的同步信号块。
在一个实施例中，与图3所示实施例相对应地，若所述最大数量L大于第一预设数值K，说明通过物理直连广播信道不足以接收L个比特的配置信息，也即充当基站的车辆通过物理直连广播信道不足以发送最大数量L个比特的配置信息，充当基站的车辆会生成比特数小于L的配置信息并发送，则接收的配置信息的比特数也小于L，其中，L＝m×n。
图9是根据本公开的实施例示出又一种根据所述最大数量与第一预设数值的关系确定接收配置信息的比特数的示意流程图。如图9所示，最大数量的同步信号块包括n个同步信号块组，每个同步信号块组包括m个同步信号块，其中，m和n为正整数，所述根据所述最大数量与第一预设数值的关系确定配置信息的比特数包括：
在步骤S235中，确定所述最大数量是否大于第一预设数值；
在步骤S236中，若所述最大数量大于第一预设数值，确定接收所述配置信息时所在的接收波束，确定接收比特数为(n-1)+(m-1)的配置信息，其中，所述(n-1)+(m-1)个比特中的(n-1)个比特用于指示所述接收波束对应的同步信号块所在的同步信号块组以外的(n-1)个同步信号块组中每个同步信号块组是否为需要发送的同步信号块组，所述(n-1)+(m-1)个比特中的(m-1)个比特用于指示需要发送的同步信号块中所述接收波束对应的同步信号块以外的(m-1)个同步信号块中每个同步信号块是否为需要发送的同步信号块。
在一个实施例中，与图4所示实施例相对应地，若所述最大数量大于第一预设数值，充当基站的车辆发送的配置信息的比特数为(n-1)+(m-1)，可以确定接收的配置信息的比特数也为(n-1)+(m-1)。
进而在解析配置信息时，由于已经知道接收所述配置信息时所在的接收波束(例如可以在与充当基站的车辆建立通信连接时确定)，那么可以确定该接收波束对应的同步信号块必然被接收到，而同步信号块是存在标识的，根据同步信号块标识可以确定同步信号块是第几组的第几个同步信号块。
例如以L＝64，m＝8，n＝8为例，同步信号块标识为从0至63，那么若确定接收波束对应的同步信号块的标识为7，也即第1行第8个同步信号块必然被接到，基 于此可以对接收到的比特数为(n-1)+(m-1)的配置信息进行补全。
例如在前(n-1)个比特指示所述接收波束对应的同步信号块所在的同步信号块组以外的(n-1)个同步信号块组中每个同步信号块组是否为需要发送的同步信号块组，后(m-1)个比特用于指示需要发送的同步信号块中所述接收波束对应的同步信号块以外的(m-1)个同步信号块中每个同步信号块是否为需要发送的同步信号块的情况下，接收到的配置信息中前(n-1)个比特为0111101，后(m-1)个比特为1100111，可以在前(n-1)个比特的第1位可以补1，得到前n个比特10111101，在后(m-1)个比特的第8位补1，得到后m个比特11001111，进而基于补全后的配置信息进行解析。

在步骤S27中，在通过物理直连广播信道接收所述配置信息之前，确定所述配置信息的比特数是否大于第二预设数值；
若所述配置信息的比特数大于第二预设数值，所述通过物理直连广播信道接收所述配置信息包括：
在步骤S241中，通过物理直连广播信道接收所述配置信息中第二预设数值比特的信息，通过其他信道接收所述配置信息中其他比特的信息。
在一个实施例中，与图5所示实施例相对应地，若所述配置信息的比特数大于第二预设数值，充当基站的车辆可以通过物理直连广播信道广播所述配置信息中第二预设数值比特的信息，通过其他信道传输所述配置信息中其他比特的信息，则本实施例中充当用户设备的车辆通过物理直连广播信道接收所述配置信息中第二预设数值比特的信息，通过其他信道接收所述配置信息中其他比特的信息。
