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公开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、本公开的一些方面相一致的装置和方法的例子。
相关技术中，业内提出需要实现非授权频段独立组网，即不依赖于新空口(NR)小区，由非授权频段的小区完成初始接入等所有功能。首先需要在非授权频段小区中SSB传输，但是业内尚无有效的解决方案。一种可能的解决方案是，沿用NR小区的SSB设计方案。该设计方案需遵循非授权频段的先听后发(Listen before Talk，LBT)原则，即发射信号之前必须要先探测能量，如果有别人在这个信道发送则必须等待。在遵循LBT原则的前提下，直接沿用NR小区的SSB设计方案，可能导致UE(用户设备)搜索延迟的问题。例如，在非授权频段中，如果UE在SSB1发送的时机开始搜索SSB，而基站发送SSB1的时刻侦听到信道被占用， 那么基站就会错过发送SSB1的时机，而UE就只能等待搜索SSB2。如果SSB2和SSB3的发送也遇到上述情况，那么在这个周期内UE就无法搜索到SSB，导致UE搜索延迟。另外，因为5G(第5代通信系统)中波束扫描发送的特性，即使在SSB2和SSB3发送的时刻信道没有被占用，也可能恰巧波束方向没有对准UE，使得UE收不到发送的波束，也同样搜索不到SSB2和SSB3，导致UE搜索延迟。
为解决上述问题，本实施例提供了更多的备选传输位置，所述备选传输位置的个数大于一个周期内同步广播块的个数。即使某个备选传输位置被其它资源占用，基站也可以有其它备选传输位置供同步广播信息传输。这样，基站有更多发送同步广播信息的机会，有助于UE及时进行同步处理。
图1是根据一示例性实施例示出的一种传输同步广播信息的方法的流程图，该传输同步广播信息的方法用于基站等网络接入设备中。如图1所示，该方法包括以下步骤101-步骤103。
在步骤101中，确定待发送的同步广播块对应的备选传输位置，所述备选传输位置的个数大于一个周期内同步广播块的个数。
在步骤102中，生成包含所述同步广播块的同步广播信息。
在步骤103中，在所述备选传输位置波束扫描发送生成的所述同步广播信息。
本实施例中，一个周期内同步广播块的个数是系统根据频段预先配置的，是一个周期内最多可传输的同步广播块的个数。备选传输位置的个数也是系统预先配置的，为一个周期内备选传输位置的最大值。
相关技术中，备选传输位置的个数不大于一个周期内同步广播块的个数。而本实施例中所述备选传输位置的个数大于一个周期内同步广播块的个数。提供了更多的备选传输位置，也提供了更多数量和更多可能方向上承载同步广播信息的波束。当某个备选传输位置被其它资源占用时，基站可以有较多其它的备选传输位置供同步广播信息传输。这样，在一个周期内，基站有更多发送同步广播信息的机会，有助于UE及时搜索到同步广播信息，进行同步处理。
例如，如图2所示，以一个周期内同步广播块(SSB)的个数为4(即L＝4)为例，也就是说一个周期内最多传输4个SSB。一个子帧内最多传输2个SSB。本实施例中备选传输位置的个数大于一个周期内同步广播块的个数，也就是当L＝4时，备选传输位置的个数至少等于5。当L＝8时，备选传输位置的个数至少等于9。L还可以为64等，原理同上，此处不再赘述。备选传输位置的个数可以根据一个周期内同步广播块的个数的配置而定。在不同频段下，一个周期内同步广播块的个数不同，备选传输位置的个数也随之变化。各个备选传输位置对应的子帧和在子帧中的位置可灵活配置，位置可以不连续，也可以连续。
基站可预先通知UE配置的所有的备选传输位置，及对应的子帧，还可以有对应的半帧。
基站先确定待发送的同步广播块的同步块标识，再确定该同步块标识对应的备选传输位置，然后在所述备选传输位置波束扫描发送生成的所述同步广播信息。
在一个实施例中，备选传输位置的个数可以有多种选择，例如，所述备选传输位置的个 数为一个周期内同步广播块的个数的n倍；其中，n＝2，或者n为一个周期时长相对于半帧时长的倍数。
备选传输位置的个数为一个周期内同步广播块的个数的整倍数，便于基站对备选传输位置的管理和控制，以及便于同步广播块标识的设置和通知用户设备同步广播块标识与子帧号的对应关系，还有助于用户设备对同步广播块标识的识别。
例如，以n＝2为例，当L＝4时，备选传输位置的个数为8。当L＝8时，备选传输位置的个数为16。又如，n为一个周期时长相对于半帧时长的倍数。一个周期时长为20ms，半帧时长为5ms，则n＝4。当L＝4时，备选传输位置的个数为16。当L＝8时，备选传输位置的个数为32。即，可以在4个半帧中均可配置备选传输位置，在一个周期内提供了更多的备选传输位置，并且备选传输位置分布在多个半帧中。即使错过一个半帧，也可以在一个周期内的其它半帧中传输SSB，有更多的选择和传输机会。
在一个实施例中，所述同步广播信息还包括所述同步广播块的同步广播块标识；所述同步广播块标识携带在所述同步广播块中。
其中，所述同步广播块标识的最大值与一个周期内同步广播块的个数相对应。
或者，所述同步广播块标识的最大值与所述备选传输位置的个数相对应。
例如，以n＝2为例，当L＝4时，备选传输位置的个数为8，对应8个SSB。这8个SSB的同步广播块标识如何配置，有多种解决方案。第一种解决方案：所述同步广播块标识的最大值与一个周期内同步广播块的个数相对应。L＝4，则同步广播块标识的最大值为3，从0开始编号，有SSB0、SSB1、SSB2和SSB3。而备选传输位置的个数为8，那就有两组SSB0、SSB1、SSB2和SSB3，如图3所示。两组SSB可以在同一个半帧中，或者两组SSB分别在两个半帧中，一组SSB在一个半帧中。哪些半帧，半帧中的哪些子帧作为备选传输位置，可灵活配置。
虽然总共有8个SSB，但是一个周期内最多传输4个SSB。备选传输位置与同步广播块标识有固定的对应关系，一旦选择了备选传输位置，便在该备选传输位置传输相应的同步广播块标识，与之前发送的同步广播块标识无关。
第二种解决方案：所述同步广播块标识的最大值与所述备选传输位置的个数相对应。备选传输位置的个数为8，则同步广播块标识的最大值为7，从0开始编号，有SSB0、SSB1、……、SSB6和SSB7。如图4所示，同样的，虽然总共有8个SSB，但是一个周期内最多传输4个SSB。备选传输位置与同步广播块标识有固定的对应关系，一旦选择了备选传输位置，便在该备选传输位置传输相应的同步广播块标识，与之前发送的同步广播块标识无关。
在一个实施例中，所述同步广播块标识通过所述同步广播块中的PBCH(物理广播信道，Physical Broadcast CHannel)信道的DMRS(Demodulation Reference Signal，解调参考信号)序列和PBCH中的数据位传输。
以n＝2为例，当采用上述第二种解决方案时，即所述同步广播块标识的最大值与所述备选传输位置的个数相对应。L＝4，备选传输位置的个数为8，则同步广播块标识的最大值为7，同步广播块标识占3位。L＝8，备选传输位置的个数为16，则同步广播块标识的最大值为15， 同步广播块标识占4位。L＝64，备选传输位置的个数为128，则同步广播块标识的最大值为127，同步广播块标识占6位。因此，相关技术中PBCH信道的DMRS序列中为同步广播块标识预留的位数无法满足需要，本实施例借用了PBCH中的数据位。利用PBCH信道的DMRS序列和PBCH中的数据位共同传输同步广播块标识。其中，同步广播块标识可以占用PBCH信道的DMRS序列中的低3位，以及占用PBCH中的3个数据位。基站将实际发送的SSB所在的子帧和在子帧中的同步广播块标识在RMSI(剩余关键系统信息)中发送给UE。
在一个实施例中，所述步骤103包括：步骤A。
在步骤A中，在选定的备选发送时隙上的所述备选传输位置波束扫描发送生成的所述同步广播信息。
其中，所述备选发送时隙的候选集合为{10,20,40,80,160}ms。
或者，一个周期内同步广播块的个数为4时，所述备选发送时隙的候选集合为{5,10,20,40,80,160}ms；一个周期内同步广播块的个数大于4时，所述备选发送时隙的候选集合为{10,20,40,80,160}ms。
由前述可知，本实施例增加了备选传输位置，多个备选传输位置可能对应多个子帧。以半帧时长5ms为例，当L＝8，n＝2时，备选传输位置的个数为16，至少对应8个子帧，对应两个半帧。如果备选发送时隙为5ms，那么到10ms时又到达一个备选发送时隙，而此时不能满足两个半帧的需求。因此，本实施例中L＝4,8,64且n至少为2时，备选发送时隙的候选集合为{10,20,40,80,160}ms。或者，一个周期内同步广播块的个数为4时，所述备选发送时隙的候选集合为{5,10,20,40,80,160}ms；一个周期内同步广播块的个数大于4时，所述备选发送时隙的候选集合为{10,20,40,80,160}ms。
在一个实施例中，所述方法还包括：步骤B1和步骤B2。
在步骤B1中，检测所述备选传输位置是否空闲；
在步骤B2中，在检测出所述备选传输位置未空闲时，放弃在所述备选传输位置波束扫描发送生成的所述同步广播信息。确定下一个备选传输位置，相当于继续步骤101。
在检测出所述备选传输位置空闲时，继续步骤102。
基站在选中一个备选传输位置后，检测该备选传输位置是否空闲，如果空闲，则可以用来传输SSB。如果未空闲，在需要再次选择一个备选传输位置。该再次选择的备选传输位置，可以是该备选传输位置相邻的下一个备选传输位置，也可以是相隔L后的备选传输位置。例如，当前选中的备选传输位置对应SSB0，而当前选中的备选传输位置未空闲，放弃传输SSB0，则选择SSB1对应的备选传输位置，或者选择SSB0+L对应的备选传输位置。又如，预计传输SSB0和SSB2，检测SSB0对应的备选传输位置未空闲，则更改为传输SSB1和SSB2，或者更改为传输SSB2和SSB0+L。
在一个实施例中，至少两个待发送的同步广播块属于一组。
所述方法还包括：步骤B1、步骤B3和步骤B4。
在步骤B1中，检测所述备选传输位置是否空闲。
在步骤B3中，当所述备选传输位置未空闲时，确定所述待发送的同步广播块所在组内的所有同步广播块。
在步骤B4中，放弃在所述所在组内所有同步广播块对应的备选传输位置波束扫描发送生成的所述同步广播信息。
当所述备选传输位置空闲时，确定组内下一个待发送的同步广播块，检测该同步广播块对应的备选传输位置是否空闲。当组内所有的同步广播块对应的备选传输位置均空闲时，在对应的各个备选传输位置波束扫描发送同步广播信息。
本实施例可以预先将多个同步广播块归为一组，例如，SSB1和SSB2属于一组。当前待发送的同步广播块为SSB1。检测SSB1对应的备选传输位置是否空闲，如果未空闲，确定SSB1所在组内还有SSB2，确定SSB2对应的备选传输位置。放弃在SSB1和SSB2对应的备选传输位置波束扫描发送生成的所述同步广播信息。
基站还可以在其它备选传输位置上传输SSB1和SSB2，或者传输其它的SSB。
本实施例提出了同步广播块组，将多个同步广播块归为一组。一组中的所有同步广播块统一管理和控制，要么统一发送，要么统一放弃发送，便于同步广播块的集中管理。
下面通过一个实施例详细介绍实现过程。
图5是根据一示例性实施例示出的一种传输同步广播信息的方法的流程图，该传输同步广播信息的方法用于基站等网络接入设备中。如图1所示，该方法包括以下步骤501-步骤502。
在步骤501中，确定待发送的同步广播块对应的备选传输位置，所述备选传输位置的个数大于一个周期内同步广播块的个数。
在步骤502中，检测所述备选传输位置是否空闲；在检测出所述备选传输位置未空闲时，放弃在所述备选传输位置波束扫描发送生成的所述同步广播信息。确定下一个备选传输位置，相当于继续步骤501。在检测出所述备选传输位置空闲时，继续步骤503。
在步骤503中，生成包含所述同步广播块的同步广播信息。
在步骤504中，在选定的备选发送时隙上的所述备选传输位置波束扫描发送生成的所述同步广播信息。
以上介绍了基站侧传输同步广播信息的实现过程。相对应的，UE侧需要对应的接收同步广播信息，并进行同步处理。下面介绍UE侧的实现过程。
图6是根据一示例性实施例示出的一种传输同步广播信息的方法的流程图，该传输同步广播信息的方法用于基站等网络接入设备中，其中，终端可以是移动电话，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6所示，该方法包括以下步骤601-步骤603。
在步骤601中，接收基站发送的同步广播信息。
在步骤602中，依据所述同步广播信息解析出同步广播块，获取同步广播块标识。
在步骤603中，根据预设的同步广播块标识与子帧号的对应关系，确定获取的所述同步广播块标识对应的子帧号。
如图3、图4所示，UE可预先通过RMSI获知SSB所在的子帧和在子帧中的同步广播块标识。当UE解析出同步广播块标识时，便可确定对应的子帧号。进而确定该同步广播块标识的波束方向，作为上行发送信号的参考，完成同步。
在一个实施例中，所述同步广播块标识的最大值与备选传输位置的个数相对应。
所述方法还包括：步骤C1。
在步骤C1中，根据所述备选传输位置的个数与一个周期内同步广播块的个数的对应关系，对获取的所述同步广播块标识进行换算。
所述步骤603包括：步骤C2。
在步骤C2中，确定换算后的同步广播块标识对应的子帧号。
以n＝2，L＝4为例，备选传输位置的个数为8，同步广播块标识包括：SSB0、SSB1、……、SSB6和SSB7。一组SSB包括SSB0、SSB1、SSB2和SSB3，另一组SSB包括SSB4、SSB5、SSB6和SSB7，两组SSB分别位于两个半帧。则同步广播块标识与子帧号的对应关系可以简化为表1。
表1
同步广播块标识 子帧号
SSB0 子帧0
SSB1 子帧1
SSB2 子帧2
SSB3 子帧3
这样，可兼容相关技术中同步广播块标识与子帧号的对应关系的通知方式。例如UE识别出同步广播块标识为SSB6，根据所述备选传输位置的个数与一个周期内同步广播块的个数的对应关系，对获取的所述同步广播块标识进行换算。该例子中n＝2，则SSB6除以2，向上取整后再减1(因为从0开始编号，所以减1)，得SSB2。确定SSB2对应的子帧号为子帧2。
当然，表1也可以变化为SSB0、SSB1、……、SSB6和SSB7与子帧号的对应关系，可以增加同步广播块标识和子帧号与半帧号的对应关系。
如果所述同步广播块标识的最大值与一个周期内同步广播块的个数相对应，则UE可以直接根据表1确定对应的子帧号，不需要对同步广播块标识进行换算。
在一个实施例中，所述步骤602包括：步骤D1-步骤D2。
在步骤D1中，所述依据所述同步广播信息解析出同步广播块中的PBCH信道的DMRS序列和PBCH中的数据位。
在步骤D2中，通过所述同步广播块中的PBCH信道的DMRS序列和PBCH中的数据位，获取同步广播块标识。
UE预先获知同步广播块标识在PBCH信道的DMRS序列和PBCH中的数据位中传输。PBCH信道的DMRS序列承载同步广播块标识中的低3位，PBCH中的数据位承载同步广播块标识中 的高2位。
下面通过一个实施例详细介绍实现过程。
图7是根据一示例性实施例示出的一种传输同步广播信息的方法的流程图，该传输同步广播信息的方法用于基站等网络接入设备中，其中，终端可以是移动电话，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7所示，该方法包括以下步骤701-步骤703。
在步骤701中，接收基站发送的同步广播信息。
在步骤702中，所述依据所述同步广播信息解析出同步广播块中的PBCH信道的DMRS序列和PBCH中的数据位。

在步骤705中，根据预设的同步广播块标识与子帧号的对应关系，确定换算后的同步广播块标识对应的子帧号。
