具体实施方式
如背景技术中所述，现有技术中下行信道信号强度较弱，不能满足某些场景对下行信道信号的需求，如用户设备(User Equipment,UE)的接收天线少，或处于较低覆盖的场景。
本申请发明人发现，SSB包括主同步信号(Primary Synchronization Signal,PSS)、辅同步信号(Secondary Synchronization Signal,SSS)以及PBCH，PSS和SSS都是序列，实际接收性能较好，但PBCH具有承载信息，有编码，其接收信号较差。故而为了提升下行信道信号的覆盖，可以增强PBCH的接收性能。
本发明技术方案通过确定重复发送时机，并在重复发送时机上实现对PBCH的重复发送，从而增加PBCH的发送机会，使得用户设备接收到PBCH的概率增大，进而实现PBCH的覆盖的增强。
本方明技术方案可适用于5G(5 Generation)通信系统，还可适用于4G、3G通信系统，还可适用于未来新的各种通信系统，例如6G、7G等。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种PBCH重复发送方法的流程图。
所述PBCH重复发送方法可以用于网络设备侧，如可以用于基站侧，也即可以由基站执行图1所示的各个步骤。
所述PBCH重复发送方法可以包括以下步骤：
步骤S101：确定PBCH的重复发送时机为传输SSB集合的时隙、非传输所述SSB集合的时隙和/或同步信号搜索窗口，所述SSB集合包括多个SSB，每一SSB包括PBCH；
步骤S102：在所述重复发送时机重复发送所述SSB集合内至少一个PBCH。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
本实施例中，重复发送时机是用于重复发送PBCH的。重复发送时机的具体时域位置可以由通信标准协议预先约定。
在步骤S101的具体实施中，基站可以由预先约定的通信标准协议确定PBCH的重复发送时机，或者，基站自主确定PBCH的重复发送时机，也即重复发送时机可以是传输SSB集合的时隙、非传输所述SSB集合的时隙或者同步信号搜索窗口，或者也可以是上述三种的任意两种或三种的组合。
其中，传输SSB集合的时隙是指用于传输SSB集合的时隙；非传输所述SSB集合的时隙是指未用于传输SSB集合的时隙，具体可以是空闲时隙；同步信号搜索窗口是指用户设备(User Equipment,UE)搜索同步信号的窗口，该窗口的大小可以是5ms。
进而在步骤S102的具体实施中，基站可以在重复发送时机重复发送所述SSB集合内至少一个PBCH。具体而言，SSB集合可以包括多个SSB，每一SSB包括一个PBCH，也即SSB集合内包括多个PBCH。基站在重复发送时机能够发送的PBCH的数量可以是一个， 也可以是多个。
更进一步地，基站在重复发送时机内可以对要发送的PBCH重复发送一次，也可以重复发送多次。
本发明实施例通过确定重复发送时机，并在重复发送时机上实现对PBCH的重复发送，从而增加PBCH的发送机会，使得用户设备接收到PBCH的概率增大，进而实现PBCH的覆盖的增强。
在本发明一个非限制性的实施例中，图1所示步骤S101可以包括以下步骤：根据子载波间隔以及所述SSB集合内能够发送的SSB的最大数量确定非传输所述SSB集合的时隙的位置。
本实施例中，重复发送时机为非传输所述SSB集合的时隙。
如背景技术中所述，3GHz以下频段中，SSB集合内能够发送的SSB的最大数量Lmax＝4；5GHz以下频段中，SSB集合内能够发送的SSB的最大数量Lmax＝8；5GHz以上频段中，SSB集合内能够发送的SSB的最大数量Lmax＝64。
具体请参照图2，图2所示Case A表示子载波间隔为15kHz时的情况：SSB的第一个时域符号位于{2,8}+14×n，当载波频率小于等于3GHz时，n＝0,1；当载波频率小于等于6GHz时,n＝0,1,2,3。
图2所示Case B表示子载波间隔为30kHz时的一种情况：SSB的第一个时域符号位于{4,8,16,20}+28×n，当载波频率小于等于3GHz时，n＝0；当载波频率小于等于6GHz时,n＝0,1。
图2所示Case C表示子载波间隔为30kHz的另一种情况：SSB的第一个时域符号位于{2,8}+14×n，当载波频率小于等于3GHz时，n＝0，1；当载波频率小于等于6GHz时,n＝0,1，2，3。
图2所示Case D表示子载波间隔为120kHz时的情况：SSB的第一个时域符号位于{4,8,16,20}+28×n。当载波频率大于6GHz时,n＝0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18。
图2所示Case E表示子载波间隔为240kHz时的情况：SSB的第一个时域符号位于{8,12,16,20,32,36,40,44}+56×n。当载波频率大于6GHz时,n＝0,1,2,3,5,6,7,8。
本实施例中，根据子载波间隔以及Lmax选取非传输所述SSB集合的时隙的具体位置，可以保证非传输所述SSB集合的时隙靠近传输SSB集合的时隙，保证PBCH重复发送的发送性能。
进一步地，请参照图3，根据子载波间隔以及所述SSB集合内能够发送的SSB的最大数量确定非传输所述SSB集合的时隙的位置包括：
步骤S301：如果所述子载波间隔为15KHz或30KHz，则确定非传输所述SSB集合的时隙与当前传输SSB集合的时隙的时域偏移量为Lmax÷2，其中，Lmax为所述最大数量；
步骤S302：如果所述子载波间隔为240KHz，则确定非传输所述SSB集合的时隙与当前传输SSB集合的时隙的时域偏移量为(Lmax÷2)+4。
具体地，如果所述子载波间隔为120KHz，则确定非传输所述SSB集合的时隙与当前传输SSB集合的时隙的时域偏移量为Lmax÷8。
本实施例中，可以根据实际的需求选择性地执行步骤S301和步骤S302的其中一个步骤。
具体实施中，当前传输SSB的时隙为时隙n，重复传输时机所处的时隙与时隙n的偏移量为k。
偏移量k的数值可以随子载波间隔或最大数量Lmax的不同而不同，最大数量Lmax与载波频率相关。
具体地，子载波间隔为15KHz或30KHz时，非传输所述SSB集合的时隙为n+(Lmax÷2)。子载波间隔为240KHz时，非传输所述SSB集合的时隙为n+(Lmax÷2)+4。
在计算出偏移量k后，根据当前传输SSB的时隙n以及时域偏移量k计算非传输所述SSB集合的时隙为时隙n+k。
可以理解的是，偏移量k的值也可以直接由通信标准协议来指定，本发明实施例对此不作限制。具体地，协议可以约定非传输所述SSB集合的时隙与当前传输SSB集合的时隙的时域偏移量为预设值。由此，基站可以根据协议确定预设值，再确定当前传输SSB集合的时隙的具体位置。
在本发明一个非限制性的实施例中，请参照图4，图1所示步骤S102可以包括以下步骤：
步骤S401：在所述重复发送时机为非传输所述SSB集合的时隙时，确定单个PBCH的重复传输次数以及单个PBCH在一次传输时占用的符号数量；
步骤S402：根据单个PBCH的重复传输次数以及单个PBCH在一次传输时占用的符号数量确定能够在非传输所述SSB集合的时隙内发送的PBCH的类型的数量；
步骤S403：在非传输所述SSB集合的时隙内，按照单个PBCH的重复传输次数以及单个PBCH在一次传输时占用的符号数量发送每一类型的PBCH。
由于非传输所述SSB集合的时隙可以是空闲时隙，因此可以在整个时隙的空闲符号上传输至少一个PBCH，具体可以先确定单个PBCH的重复传输次数以及单个PBCH在一次传输时占用的符号数量来确定要发送的各个PBCH占用的符号。
一并参照图5，重复发送时机为时隙n+k，时隙n+k包括14个符号。可以确定单个PBCH的重复传输次数为1以及单个PBCH在一次传输时占用的符号数量为3，那么在该时隙n+k能够发送四种类型的PBCH，也即SSB0中的PBCH，SSB1中的PBCH，SSB2中的PBCH以及SSB3中的PBCH。具体地，SSB0中的PBCH位于符号2、3和 4，SSB1中的PBCH位于符号5、6和7，SSB2中的PBCH位于符号8、9和10，SSB3中的PBCH位于符号11、12和13。
或者，可以确定单个PBCH的重复传输次数为2以及单个PBCH在一次传输时占用的符号数量为3，那么在该时隙n+k能够发送2种类型的PBCH，也即SSB0中的PBCH和SSB1中的PBCH。具体地，第一次重复传输的SSB0中的PBCH位于符号2、3和4，第二次重复传输的SSB0中的PBCH位于符号5、6和7；第一次重复传输的SSB1中的PBCH位于符号8、9和10，第二次重复传输的SSB1中的PBCH位于符号11、12和13。
可以理解的是，由于每个时隙内的前两个符号，也即符号0和符号1通常用于传输重要数据，因此在重复发送PBCH时避免占用时隙内的前两个符号。
进一步而言，单个PBCH在一次传输时占用的符号数量为3，单个PBCH在每个符号上占用16个资源块；或者，单个PBCH在一次传输时占用的符号数量为2，单个PBCH在每个符号上占用20个资源块；或者，单个PBCH在一次传输时占用的符号数量为3，单个PBCH在前两个符号上分别占用20个资源块，单个PBCH在第三个符号上占用8个资源块。
本实施例中，PBCH需要占用48个资源块(Resource Block,RB)。单个PBCH在一次传输时占用的符号数量为3时，其可以在每个符号上占用16个RB。
或者，单个PBCH在一次传输时占用的符号数量为2，其可以在每个符号上占用20个资源块。在这种情况下，PBCH共占用40个RB，故而重复发送的PBCH仅能携带原始PBCH的部分信息。
或者，单个PBCH在一次传输时占用的符号数量为3，单个PBCH在前两个符号上分别占用20个RB，单个PBCH在第三个符号上占用8个RB。重复发送的PBCH在第三个符号上占用8个RB的位置 可以是第三个符号在频域上的中间8个RB，或者可以是第三个符号在频域上的最高8个RB，或者可以是第三个符号在频域上的最低8个RB，或者还可以是第三个符号在频域上的最低4个RB与最高4个RB。
在本发明一个非限制性的实施例中，图1所示步骤S102可以包括以下步骤：在所述重复发送时机为传输所述SSB集合的时隙时，确定传输所述SSB集合的时隙内的空闲符号；在所述空闲符号上重复发送所述SSB集合内的PBCH。
本发明实施例可以在传输所述SSB集合的时隙内的空闲符号商重复发送PBCH。
具体地，请一并参照图2，对于子载波间隔为15kHz时的情况，SSB集合内的SSB0和SSB1分别占用当前时隙内的符号2-5，以及符号8-11，当前时隙内的空闲符号为符号0、1、6、7、12和13。
如前所述，由于每个时隙内的前两个符号，也即符号0和符号1通常用于传输重要数据，因此在重复发送PBCH时避免占用时隙内的前两个符号。故而可以在符号6和7上重复发送SSB0的PBCH，在符号12和13上重复发送SSB1的PBCH。
进一步地，单个PBCH在一次传输时占用的符号数量为2，单个PBCH在每个符号上占用20个资源块，单个PBCH在主同步信号所在的符号上占用8个资源块。
本实施例中，一并参照图2，由于仅有两个符号(共40RB)供重复发送PBCH，而PBCH需要占用48个RB，并且PSS所在符号上具有空闲的资源块，因此重复发送的PBCH除了在两个空闲符号上分别占用20个RB之外，剩余的8个RB可以位于PSS所在符号。
在本发明一个非限制性的实施例中，图1所示步骤S102可以包括以下步骤：在所述重复发送时机为所述同步信号搜索窗口时，确定在所述同步信号搜索窗口内的空闲时隙；利用所述空闲时隙重复发送 所述SSB集合。
本实施例中，重复发送的内容不仅包括PBCH，还包括PSS和SSS，也即可以对SSB集合进行重复发送。
由于UE是在同步信号搜索窗口内对同步信号进行搜索的，因此可以在同步信号搜索窗口内的空闲时隙重复发送SSB集合。
具体地，请一并参照图6，在同步信号搜索窗口的长度为5ms时，对于子载波间隔为30KHz的SSB集合，传输SSB集合所占用时隙为时隙0-3(共占用4个时隙)，同步信号搜索窗口的空闲时隙为时隙4-9(也即空白时隙数量为6，大于传输SSB集合所需要的时隙数量)，故而可以在时隙4-9重复传输SSB集合。同理，对于子载波间隔为30KHz的SSB集合，也可以在长度为5ms的同步信号搜索窗口内重复传输SSB集合。
对于子载波间隔为15KHz和120KHz的SSB集合，由于长度为5ms的同步信号搜索窗口内的空闲时隙较少，也即小于传输SSB集合所需要的时隙数量，不能够传输全部的SSB集合，因此在这种情况下，可以增加同步信号搜索窗口的时间长度，例如，同步信号搜索窗口的长度为10ms，本发明实施例对此不作限制。
请参照图7，所述PBCH重复接收方法可以用于用户设备侧，也即可以由UE执行图7所示的各个步骤。
所述PBCH重复接收方法可以包括以下步骤：
步骤S701：确定PBCH的重复发送时机为传输SSB集合的时隙、非传输所述SSB集合的时隙和/或同步信号搜索窗口，所述SSB集合包括多个SSB，每一SSB包括PBCH；
步骤S702：在所述重复发送时机重复接收所述SSB集合内至少一个PBCH。
本发明实施例中，UE通过确定重复发送时机，并在重复发送时 机上实现对PBCH的重复接收，从而增加PBCH的接收机会，使得用户设备接收到PBCH的概率增大，进而实现PBCH的覆盖的增强。
请参照图8，PBCH重复发送装置80可以包括：
