具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中，业内近期对5G(第5代移动通信系统)非授权频谱进行了立项研究，提出支持5G非授权小区单独组网的方案。在5G非授权频谱独立组网设计上，第一步就是要考虑关于同步广播块(SS/PBCH BLOCK，以下简写为SSB)的设计。对于非授权频谱，需要遵守LBT(listen before talk，先听后发)原则。在需要传输SSB时，在LBT原则下，可能因为时频资源被占用而无法在系统固定配置的位置传输SSB。此时，可能在系统允许的备选偏移传输位置再次尝试发送SSB，以便用户设备(UE)及时的与网络侧同步。无论是在系统固定配置的位置还是在备选偏移传输位置上发送SSB，在发送SSB的同时，还需要通知UE实际发送位置是什么。以便UE对SSB及下行信道上的其它信息进行解析。
相关技术中，在5G系统中，利用16比特(bit)来传输实际发送位置指示信息，其中前8比特指示每个SSB的传输情况。如果是系统规定的一个传输单元内同步广播块的最大个数L＝4，则占用前8比特中的前4比特即可。如果L＝8，则占用前8比特即可。如果L＝64，则前8比特指示一组8个SSB的传输情况，后8比特指示8组的传输情况，这就要求8组的组内传输情况必须一致，要么不传，要传就必须一致。本公开的发明人发现，当SSB在备选偏移传输位置上传输时，前8比特将无法指示每个SSB的传输情况。由此可见，相关技术中的实际发送位置指示信息无法兼容非授权频谱的需求。
为解决上述问题，本实施例提供一种新的实际发送位置指示信息，所述实际发送位置指示信息包括第一指示域、第二指示域和第三指示域；第一指示域和第二指示域共同指示所述一组同步广播块的实际发送位置，新增的第三指示域指示一组同步广播块中当前的同步广播块对应第一指示域或对应第二指示域。
图1是根据一示例性实施例示出的一种传输同步指示信息的方法的流程图，该传输同步指示信息的方法用于基站等接入网设备。如图1所示，该方法包括以下步骤101-103。
在步骤101中，确定一组同步广播块的实际发送位置。
在步骤102中，根据所述实际发送位置，生成实际发送位置指示信息；其中，所述实际发送位置指示信息包括第一指示域、第二指示域和第三指示域；第一指示域和第二指示域共 同指示所述一组同步广播块的实际发送位置，第三指示域指示一组同步广播块中当前的同步广播块对应第一指示域或对应第二指示域。
在步骤103中，在所述实际发送位置传输所述同步广播块，以及通过剩余关键系统信息(RMSI)传输所述实际发送位置指示信息。
本实施例中，每发送一个同步广播块时，均同步发送与该同步广播块时对应的实际发送位置指示信息。所述一组同步广播块包括至少两个同步广播块时，所述至少两个同步广播块的实际发送位置连续。该一组同步广播块中的每个同步广播块对应的实际发送位置指示信息中，第一指示域和第二指示域的信息是相同的，因为第一指示域和第二指示域共同指示所述一组同步广播块的实际发送位置，而不是单独的某一个同步广播块的实际发送位置。但是，一组同步广播块中的每个同步广播块对应的实际发送位置指示信息中，第三指示域的信息可能不同。
如图2所示，第一行为第一指示域，第二行为第二指示域，一个方块表示1比特位指示信息，同时也代表着一个同步广播块对应的时频资源(以下称时隙块)。阴影表示当前发送的同步广播块，数字1表示该时频资源上有同步广播块传输。本实施例中阴影位于第一行，即对应第一指示域，则第三指示域的值为0，即指向第一指示域。(当然，系统也可以规定第三指示域的值为1时指向第一指示域。)UE收到第三指示域，确定当前收到的同步广播块对应第一指示域，则可根据第一指示域解析当前下行信道的其它信息。UE也可以根据第三指示域知道后面还有第二指示域，可根据第二指示域解析后面收到的下行信道的其它信息(即下行信道中除SSB以外的其它信息)。
如图3所示，本实施例中阴影位于第二行，即对应第二指示域，则第三指示域的值为1，即指向第二指示域。(当然，系统也可以规定第三指示域的值为0时指向第二指示域。)UE收到第三指示域，确定当前收到的同步广播块对应第二指示域，则可根据第二指示域解析当前下行信道的其它信息。UE也可以根据第三指示域知道前面还有第一指示域，可根据第一指示域解析前面收到的下行信道的其它信息。
本实施例中一组同步广播块需要在两组时隙块中完成传输。基站在进行时频资源是否被占用的探测时，就要保证在两组时隙块中可以完成一组同步广播块的传输。否则放弃在该两组时隙块中传输同步广播块。
在一个实施例中，第三指示域占用1比特。
本实施例中第三指示域仅占用1比特，占用的网络资源较少，对网络影响较小。
在一个实施例中，第一指示域和第二指示域缺省当前的同步广播块的指示信息。
本实施例中图2和图3所示的阴影方块可以缺省，即缺省当前的同步广播块的指示信息。如果阴影方块位于第一行，则第一指示域缺省当前的同步广播块的指示信息。如果阴影方块位于第二行，则第二指示域缺省当前的同步广播块的指示信息。
UE在收到实际发送位置指示信息后，可以根据SSB的序号以及第三指示域，在第一指示域和第二指示域中填充上该指示信息。例如L＝8，则SSB的序号为SSB0……SSB7。以图2为 例，假设当前的同步广播块是SSB5，第一指示域和第二指示域中是连续的7个1。则在第2个1和第3个1之间填充一个1，补足8个1。
当前的同步广播块对应的指示信息可能位于第一指示域，也可能位于第二指示域。所以，第一指示域和第二指示域共同缺省当前的同步广播块的指示信息。
在一个实施例中，第一指示域和第二指示域最多占用16比特。
本实施例中第一指示域和第二指示域最多占用16比特。可与5G新空口(NR)系统兼容。并且，在第一指示域和第二指示域缺省当前的同步广播块的指示信息的情况下，还可以节省1比特，即占用15比特。
在一个实施例中，所述实际发送位置包括相对于系统配置的首选传输位置偏移后的位置，所述第二指示域位置生效。
本实施例支持5G新空口(NR)系统的规定，同步广播块可以在系统配置的固定位置传输。那么，以L＝8为例，第一指示域为满位图，即第一指示域中的8个方块均为1，没有空。
本实施例也可以支持5G非授权频谱的规定，在遵守LBT原则时，以图2为例，第一行的0-2所对应的时隙块可能被占用，导致SSB0-SSB2无法正常发送，所以在第二行的0-2所对应的时隙块中发送SSB0-SSB2。第二行的0-2所对应的时隙块即为偏移后的位置，即第二指示域位置生效。本实施例适用于L＝4或L＝8的情况。
本实施例中的实际发送位置指示信息针对上述两种情况均可以实现对实际发送位置的指示。
在一个实施例中，所述实际发送位置指示信息还包括第四指示域，指示一组同步广播块内同步广播块的重复次数。
本实施例中，同步广播块不仅可以在系统规定的固定位置上发送，还可以在备选的偏移位置上发送，支持同步广播块重复发送。当同步广播块重复发送时，在实际发送位置指示信息中增加第四指示域，指示一组同步广播块内同步广播块的重复次数。
例如，第一指示域和第二指示域总共为16比特，对应16个时隙块。L＝8，则可重复2次。第四指示域的值为1，表示存在重复发送的情况，重复次数为1，值为0表示不存在重复发送的情况。
在一个实施例中，所述第四指示域最多占用2比特。
如前所述，例如，第一指示域和第二指示域总共为16比特，对应16个时隙块。L＝4，则可重复4次。所以，所述第四指示域最多占用2比特，来表示最多4次的情况。
以上介绍了基站侧的实现过程，相应的，用户设备侧也有所改进，下面针对用户设备侧介绍实现过程。
图4是根据一示例性实施例示出的一种传输同步指示信息的方法的流程图，该传输同步指示信息的方法用于用户设备，其中，用户设备可以是移动电话，计算机，数字广播终端，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。如图4所示，该方法包括以下步骤401-402。
在步骤401中，接收同步广播块和通过剩余关键系统信息(RMSI)传输的所述实际发送位置指示信息；其中，所述实际发送位置指示信息包括第一指示域、第二指示域和第三指示域；第一指示域和第二指示域共同指示所述一组同步广播块的实际发送位置，第三指示域指示一组同步广播块中当前接收的同步广播块对应第一指示域或对应第二指示域。
在步骤402中，根据所述同步广播块和实际发送位置指示信息进行同步处理。
继续前面的例子，如图2所示，第一行为第一指示域，第二行为第二指示域，一个方块表示1比特位指示信息，同时也代表着一个同步广播块对应的时频资源(以下称时隙块)。阴影表示当前发送的同步广播块，数字1表示该时频资源上有同步广播块传输。本实施例中阴影位于第一行，即对应第一指示域，则第三指示域的值为0，即指向第一指示域。(当然，系统也可以规定第三指示域的值为1时指向第一指示域。)UE收到第三指示域，确定当前收到的同步广播块对应第一指示域，则可根据第一指示域解析当前下行信道的其它信息。UE也可以根据第三指示域知道后面还有第二指示域，可根据第二指示域解析后面收到的下行信道的其它信息(即下行信道中除SSB以外的其它信息)。
如图3所示，本实施例中阴影位于第二行，即对应第二指示域，则第三指示域的值为1，即指向第二指示域。(当然，系统也可以规定第三指示域的值为0时指向第二指示域。)UE收到第三指示域，确定当前收到的同步广播块对应第二指示域，则可根据第二指示域解析当前下行信道的其它信息。UE也可以根据第三指示域知道前面还有第一指示域，可根据第一指示域解析前面收到的下行信道的其它信息。
在一个实施例中，第三指示域占用1比特。
本实施例中第三指示域仅占用1比特，占用的网络资源较少，对网络影响较小。
在一个实施例中，第一指示域和第二指示域缺省当前的同步广播块的指示信息。
所述步骤402包括：步骤A1和步骤A2。
在步骤A1中，根据所述同步广播块中的序号，确定所述同步广播块在第一指示域和第二指示域中缺省的位置，并补充该缺省的位置。
在步骤A2中，根据所述同步广播块和补充后的实际发送位置指示信息进行同步处理。
本实施例中图2和图3所示的阴影方块可以缺省，即缺省当前的同步广播块的指示信息。如果阴影方块位于第一行，则第一指示域缺省当前的同步广播块的指示信息。如果阴影方块位于第二行，则第二指示域缺省当前的同步广播块的指示信息。
UE在收到实际发送位置指示信息后，可以根据SSB的序号以及第三指示域，在第一指示域和第二指示域中填充上该指示信息。例如L＝8，则SSB的序号为SSB0……SSB7。以图2为例，假设当前的同步广播块是SSB5，第一指示域和第二指示域中是连续的7个1。则在第2个1和第3个1之间填充一个1，补足8个1。
在一个实施例中，第一指示域和第二指示域最多占用16比特。
本实施例中第一指示域和第二指示域最多占用16比特。可与5G新空口(NR)系统兼容。并且，在第一指示域和第二指示域缺省当前的同步广播块的指示信息的情况下，还可以节省 1比特，即占用15比特。
在一个实施例中，所述实际发送位置包括相对于系统配置的首选传输位置偏移后的位置，所述第二指示域位置生效。
本实施例支持5G新空口(NR)系统的规定，同步广播块可以在系统配置的固定位置传输。那么，以L＝8为例，第一指示域或者第二指示域为满位图，即第一指示域中的8个方块均为1，没有空；或者第二指示域中的8个方块均为1，没有空。
本实施例也可以支持5G非授权频谱的规定，在遵守LBT原则时，以图2为例，第一行的0-2所对应的时隙块可能被占用，导致SSB0-SSB2无法正常发送，所以在第二行的0-2所对应的时隙块中发送SSB0-SSB2。第二行的0-2所对应的时隙块即为偏移后的位置。
本实施例中的实际发送位置指示信息针对上述两种情况均可以实现对实际发送位置的指示。
在一个实施例中，所述实际发送位置指示信息还包括第四指示域，指示一组同步广播块内同步广播块的重复次数。
所述步骤402包括：步骤B1和步骤B2。
在步骤B1中，根据所述实际发送位置指示信息，对重复的相同序号的同步广播块进行合并处理。
在步骤B2中，根据合并处理后的同步广播块和实际发送位置指示信息进行同步处理。
将多个同步广播块进行合并，可以增强同步广播块的信号强度，有利于同步广播块的成功解析。即有助于同步处理。
例如，第一指示域和第二指示域总共为16比特，对应16个时隙块。L＝8，则可重复2次。第四指示域的值为1，表示存在重复发送的情况，重复次数为1，UE可以将两个同步广播块合并。值为0表示不存在重复发送的情况。
在一个实施例中，所述第四指示域最多占用2比特。
如前所述，例如，第一指示域和第二指示域总共为16比特，对应16个时隙块。L＝4，则可重复4次。所以，所述第四指示域最多占用2比特，来表示最多4次的情况。
第四指示域的值以实际重复次数为准，不一定是最大重复次数。
