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非授权频谱进行了立项研究，提出支持非授权小区单独组网的立项。在非授权频谱设计上，如何传输同步广播块和相应的RMSI的相关信息，是业内关注的焦点问题。一种可能的方案是，如图1所示，同步广播块与相应的RMSI的相关信息在时域上存在符号间隔。那么，基站需要为同步广播块和相应的RMSI(剩余关键系统信息)的相关信息进行两次探测，探测较为频繁。并且，同步广播块与相应的RMSI的相关信息的间隔较小，与无线局域网(WLAN)的共存性较差，不符合WLAN的系统要求。
为解决上述问题，本实施例中，将多个同步广播块和相应的RMSI的相关信息作为一组同步广播块和RMSI的相关信息。一次为一组同步广播块和RMSI的相关信息探测信道是否空闲，减少探测频率。并且一次发送一组同步广播块和RMSI的相关信息，减少时间间隔，可以更好的与WLAN系统共存。
图2是根据一示例性实施例示出的一种传输同步广播块和RMSI的相关信息的方法的流程图，该传输同步广播块和RMSI的相关信息的方法用于基站等网络接入设备。如图2所示，该方法包括以下步骤201-步骤202。
在步骤201中，探测当前发送时刻下信道是否空闲，以发送一组同步广播块和RMSI的相关信息；所述一组同步广播块和RMSI的相关信息至少包括一个同步广播块和相应的RMSI的相关信息。
在步骤202中，在探测到当前发送时刻下信道空闲时，波束扫描发送所述一组同步广播块和RMSI的相关信息。
本实施例中，将多个同步广播块和相应的RMSI的相关信息作为一组同步广播块和RMSI的相关信息。同步广播块和相应的RMSI的相关信息可以作为一种发现参考信号。一次为一组同步广播块和RMSI的相关信息探测信道是否空闲，减少探测频率。并且一次发送一组同步广播块和RMSI的相关信息，减少时间间隔，可以更好的与WLAN系统共存。
系统可以预先配置一组同步广播块和RMSI的相关信息的起始时域位置，当前发送时刻即为该起始时域位置。例如，在低频段，起始时域位置是第3个时域符号，为一组同步广播块和RMSI的相关信息分配的时域资源长度是10个符号。那么探测第3-13的时域符号上，信道是否空闲。探测信道是否空闲，包括：探测当前发送时刻下信道的干扰能量是否超过预设的阈值，如果不超过，则确定信道空闲。探测的信道是发送频段内的信道。
又如，在高频段(6G以上的频段)，起始时域位置是第3、19个时域符号，为一组同步广播块和RMSI的相关信息分配的时域资源长度是10个符号。那么探测第3-13的时域符号上，信道是否空闲，当前发送时刻即为第3个时域符号。如果不空闲，则当前发送时刻变更为第19个时域符号。那么探测第19-29的时域符号上，信道是否空闲。
在一个实施例中，一组同步广播块和RMSI的相关信息的时长与1ms的比例不超过预设的比例范围；所述比例范围为60％-90％。
其中，在比例范围中，可以取值68％等比例值。
本实施例中，尽可能多的同步广播块和相应的RMSI的相关信息组成一组同步广播块和RMSI的相关信息，以尽可能的减少基站的探测次数和同步广播块和RMSI的相关信息的传输延迟。另一方面，一组内同步广播块和RMSI的相关信息的数量又不宜过多，同步广播块和RMSI的相关信息不宜占据太多的信道时长，影响上行信息的传输。因此，本实施例提供了一个比较合适的比例范围，平衡各方面的需求。
在一个实施例中，如图3所示，所述一个同步广播块和相应的RMSI的相关信息在时域上符号连续。
以L＝4为例，L为预先配置的一个周期内最多可传输的同步广播块的个数。在15K的低频段，一个同步广播块占4个时域符号，2个同步广播块和相应的RMSI的相关信息时隙连续，共占12个时域符号，构成一组。一个时隙内传输一组同步广播块和RMSI的相关信息。一组同步广播块和RMSI的相关信息在一个时隙内的起始位置可由基站灵活配置。在其它例子中，一个时隙内可以传输多组同步广播块和RMSI的相关信息，一组内同步广播块的数量越多，组与组之间的传输间隙可以越大，以便更好的与WLAN系统共存，以及方便上行信息传输。
其中，一个同步广播块占2个时域符号或占4个时域符号。
当一个同步广播块占4个时域符号时，对于低频段，所述一组同步广播块和RMSI的相关信息包括一个或4个同步广播块和相应的RMSI的相关信息；对于高频段，所述一组同步广播块和RMSI的相关信息包括4个或8个同步广播块和相应的RMSI的相关信息。
当一个同步广播块占2个时域符号时，对于低频段，所述一组同步广播块和RMSI的相关信息包括4个或8个同步广播块和相应的RMSI的相关信息；对于高频段，所述一组同步广播块和RMSI的相关信息包括8个或16个同步广播块和相应的RMSI的相关信息。
在一个实施例中，如图4所示，所述一个同步广播块与寻呼信息或与其它广播信息在频域上符号连续。
同步广播块、相应的RMSI的相关信息、寻呼信息和其它广播信息可以构成一个信号块。在频域上同步广播块与寻呼信息或与其它广播信息符号连续，可以满足系统对带宽占用的要求。占用的带宽尽可能满足预设的带宽比例阈值(如80％)。
在一个实施例中，如图5所示，所述一组同步广播块和RMSI的相关信息至少包括两个同步广播块时，所述两个同步广播块中，前一个同步广播块对应的RMSI的相关信息在时域上位于所述两个同步广播块之前；后一个同步广播块对应的RMSI的相关信息在时域上位于所述两个同步广播块之后。
如果一组同步广播块和RMSI的相关信息包括三个或三个以上的同步广播块，那么三个或三个以上的同步广播块中，前一部分同步广播块对应的RMSI的相关信息在时域上位于所述两个同步广播块之前；后一部分同步广播块对应的RMSI的相关信息在时域上位于所述两个同步广播块之后。前一部分包括一个或两个同步广播块，相应的，后一部分包括两个或一个同步广播块。
本实施例提供一种实现方式，例如一组同步广播块和RMSI的相关信息包括两个同步广播块，前一个同步广播块对应的RMSI的相关信息位于该组同步广播块之前；后一个同步广播块对应的RMSI的相关信息位于该组同步广播块之后。当然，该组同步广播块对应的所有RMSI的相关信息可以均位于该组同步广播块之前，或者均位于该组同步广播块之后。
在一个实施例中，所述同步广播块中预设的用于指示关于RMSI的指示位中，部分指示位用于指示关于RMSI的码点信息，剩余部分指示位保留。
相关技术中，同步广播块与对应的RMSI的相关信息之间不连续，有符号间隔，因此存在多种可能的位置关系，需要用较多的指示位来通知终端当前采用了哪种位置关系。而本实施例中，同步广播块与对应的RMSI的相关信息之间在时域上符号连续，因此可能存在的位置关系较少，采用较少的指示位便可通知终端当前采用了哪种位置关系。剩余部分指示位保留。
在一个实施例中，所述RMSI的相关信息至少包括下列之一：RMSI的数据信息和调度RMSI的控制资源集(CORESET)。RMSI的数据信息可以由PDSCH(物理下行共享信道)承载。
以上实施例可以根据需要进行自由组合。
下述为本发明装置实施例，可以用于执行本发明方法实施例。
