Abstract

一种数据传输方法及装置，通过设置对应于一个传输窗的第一SSB集合以及作为第一SSB集合的子集的第二SSB集合，并在该传输窗中发送该第二SSB集合中的至少一个SSB，能够适应不同情况下的小区覆盖并提高资源调度的灵活性。

Description

数据传输方法及装置 技术领域
本发明涉及通信领域，特别涉及一种数据传输方法及装置。
背景技术
3GPP(第3代合作伙伴计划，3rd Generation Partnership Project)正在研究下一代无线通信系统的相关议题。在下一代无线通信系统中，例如，在新无线(NR，New Radio)系统中，一个周期中的同步信号块(Sychronization Signal Block，SSB)在一个半子帧中(half sub-frame)传输，一个半子帧的长度为5ms。
在NR系统中，针对不同的频段和子载波间隔，预定义了一个半子帧中的SSB的时域位置，并通过SSB索引(SSB index)表示不同时域位置的SSB，一个SSB中的解调参考信号(DemodulationReference Sgnal，DMRS)和物理广播信道(Physical Broadcast Channel，PBCH)可指示该SSB对应的SSB index。例如，针对3～6GHz频段，一个半子帧包括预定义的8个SSB的时域位置，这8个SSB与数值为0～7的SSB index一一对应。由此，用户设备(User Equipment，UE)接收到一个SSB后，可根据该SSB对应的SSB index确定半子帧定时，进而可以结合其他信息确定帧定时。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，在NR系统中，对于SSB的设计仅考虑了授权频段。例如，针对3～6GHz频段，一个半子帧中包括8个预定义的SSB。在授权频段中，网络设备(Network Equipment)可以预先确定和保证是否发送一个SSB。
但是，在某些频段，例如非授权频段(unlicensed band)或共享频段(sharing band)中，为了公平高效地共享频谱资源，设备需要通过信道接入方法/过程判断信道未被其他设备占用时才能发送数据，因此，网络设备可能由于信道被其他设备占用而无法发送SSB。并且，SSB的发送功率以及一定时间内所能发送的SSB个数或时间长度 可能还受限于监管要求。因此，如果直接采用NR系统中的关于SSB的设计，可能无法保证某些频段下的小区覆盖。
为了解决上述问题的至少一个，本发明实施例提供了一种数据传输方法及装置。
根据本发明实施例的第一方面，提供了一种数据传输装置，设置于网络设备侧，所述装置包括：第一发送单元，其用于在第一传输窗中发送对应所述第一传输窗的第二SSB集合中的至少一个SSB，或者，不发送SSB；其中，所述第二SSB集合是第一SSB集合的子集，所述第一SSB集合中的各个SSB对应于所述第一传输窗的不同时域位置。

根据本发明实施例的第七方面，提供了一种数据传输方法，应用于用户设备侧，所述方法包括：根据第二SSB集合中的SSB的时域位置和/或准共址关系，接收下行信号和/或信道或发送上行信号和/或信道，所述第二SSB集合是第一SSB集合的子集，所述第一SSB集合中的各个SSB对应于一个传输窗的不同时域位置。
根据本发明实施例的第八方面，提供了一种计算机可读程序，其中当在数据传输 装置或网络设备中执行所述程序时，所述程序使得所述数据传输装置或网络设备执行本发明实施例的第六方面所述的数据传输方法。
根据本发明实施例的第九方面，提供一种存储有计算机可读程序的存储介质，其中所述计算机可读程序使得所述数据传输装置或网络设备执行本发明实施例的第六方面所述的数据传输方法。
根据本发明实施例的第十方面，提供了一种计算机可读程序，其中当在数据传输装置或用户设备中执行所述程序时，所述程序使得所述数据传输装置或用户设备执行本发明实施例的第七方面所述的数据传输方法。

本发明实施例的有益效果在于：通过设置对应于一个传输窗的第一SSB集合以及作为第一SSB集合的子集的第二SSB集合，并在该传输窗中发送该第二SSB集合中的至少一个SSB，能够适应不同情况下的小区覆盖并提高资源调度的灵活性。

下面结合附图对本发明实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。
实施例1
本发明实施例提供了一种数据传输方法，该方法应用于网络设备侧。
图2是本发明实施例1的数据传输方法的示意图，如图2所示，该方法包括：
步骤201：在第一传输窗中发送对应该第一传输窗的第二SSB集合中的至少一个SSB，或者，不发送SSB；其中，该第二SSB集合是第一SSB集合的子集，该第一SSB集合中的各个SSB对应于该第一传输窗的不同时域位置。
这样，通过设置对应于一个传输窗的第一SSB集合以及作为第一SSB集合的子集的第二SSB集合，并在该传输窗中发送该第二SSB集合中的至少一个SSB，能够适应不同情况下的小区覆盖并提高资源调度的灵活性。在本实施例中，第一传输窗可以是多个传输窗中的任意一个，该多个传输窗在时间轴上以一定的周期间隔设置。
在本实施例中，在不同传输窗中的发送的SSB的时域位置、QCL关系以及发送的个数可能相同，也可能不同。
在本实施例中，一个传输窗可以是一个周期性的时间传输单元，例如，该传输窗是SSB传输窗、DRS(解调参考信号，Demodulation Reference Signal)传输窗、半子帧以及子帧中的一个。
在本实施例中，第一SSB集合中的各个SSB对应于该第一传输窗的不同时域位置。其中，第一SSB集合中的SSB的数量可以根据实际需要而设置。
例如，第一SSB集合中的SSB的数量可以为8个以上，例如为16个、32个或64个。
在本实施例中，第一SSB集合是预定义的。
这里，预定义是指标准中定义第一SSB集合包含的SSB的个数、时域位置以及准共址关系中的至少一个。第一SSB集合例如是根据非授权频段监管要求定义的，以尽可能公平地共享频谱资源。
在本实施例中，根据SSB之间准共址关系也就是根据SSB对应的空域信息，例如第二索引，波束(beam)标识，对应相同且唯一空域信息的SSB是准共址的。
例如，第一SSB集合和频段(或频率范围)和/或子载波间隔(sub-carrier spacing,SCS)相关，即针对不同频段(或频率范围)和/或子载波间隔分别定义相应的第一SSB集合。
以频段为例，例如，针对频段F1～F2kHz，第一SSB集合包括SSB1～SSB8这8个SSB，针对频段F3～F4kHz，第二SSB集合包括SSB1～SSB16这16个SSB。对于其他频段，可以进行类似的设定。
例如，针对SSB的时域位置，SSB和第一索引之间的对应关系是预定义的，或者，SSB和第二索引和第三索引的关系是预定义的；
针对SSB的准共址关系，SSB和第二索引之间的对应关系是预定义的。
在本实施例中，该第一SSB集合中的各个SSB对应于该第一传输窗的不同时域位置，此处的不同时域位置是指不完全相同，也就是说，该第一SSB集合中的任意两个SSB的时域位置可以是间隔开的，也可以是部分重叠的。
图3是本发明实施例1的传输窗及第一SSB集合的一示意图。如图3所示，在时间轴上周期性的设置有多个传输窗，一个周期T例如是40ms。第一传输窗是多个传输窗中的一个，对应于第一传输窗，第一SSB集合包含16个SSB，这16个SSB在时域上相互间隔。
图4是本发明实施例1的第一SSB集合的另一示意图。如图4所示，第一SSB集合包含16个SSB，这16个SSB在时域上部分重叠。
在本实施例中，可以将第一SSB集合中的SSB称为名义SSB(nominal SSB)，但是该名称只是为了区别于现有的SSB，其也可以采用其他的名称。
在本实施例中，第二SSB集合是第一SSB集合的子集，例如，该第二SSB集合可以是第一SSB集合的本身，也可以是第一SSB集合的真子集，即包含第一SSB集合的一部分SSB。
在本实施例中，可以将第二SSB集合中的SSB称为候选SSB(candidate SSB)， 但是该名称只是为了区别于现有的SSB以及第一SSB集合中的SSB，其也可以采用其他的名称。
例如，对于第一SSB集合中的某个SSB，其是一个nominal SSB，如果该nominal SSB属于第二SSB集合，则该nominal SSB还同时是一个candidate SSB。
在步骤201中，在第一传输窗中发送对应该第一传输窗的第二SSB集合中的至少一个SSB。
在本实施例中，针对非授权频段或共享频段，根据信道检测结果，在第一传输窗中发送对应该第一传输窗的第二SSB集合中的至少一个SSB，或者，不发送SSB。
其中，第二SSB集合包括至少一个SSB。
例如，当第一传输窗中第二SSB集合中SSB对应的时域位置都未能接入信道时，不发送SSB。
例如，对于第一传输窗，可以设置SSB的最少发送次数I，则若第一传输窗中发送SSB，至少发送I个。当基站在第一传输窗中第二SSB集合中的后I个SSB中的第1个SSB对应的时域位置之前未能接入信道时，不发送SSB。
此时，第二SSB集合中时域位置不重叠的SSB的个数大于等于I。最少发送次数I是预定义的。
这里，预定义是指标准中定义了I的特定取值，I例如是根据非授权频段监管要求定义的，以尽可能公平地共享频谱资源。
例如，I和频段(或频率范围)和/或子载波间隔(sub-carrier spacing,SCS)相关，即针对不同频段(或频率范围)和/或子载波间隔分别定义相应的最少发送个数I。
以频段为例，例如，针对频段F1～F2kHz，I＝4，针对频段F3～F4kHz，I＝2。对于其他频段，可以进行类似的设定。
在本实施例中，对于第一传输窗，可以设置SSB的最大发送个数，记为X。
其中，最大发送个数X是预定义的。这里，预定义是指标准中定义了X的特定取值，X例如是根据非授权频段监管要求定义的，以尽可能公平地共享频谱资源。
例如，X和频段(或频率范围)和/或子载波间隔(sub-carrier spacing,SCS)相关，即针对不同频段(或频率范围)和/或子载波间隔分别定义相应的最大发送个数X。
以频段为例，例如，针对频段F1～F2kHz，X＝8，针对频段F3～F4kHz，X＝4。 对于其他频段，可以进行类似的设定。
例如，该第二SSB集合中的SSB的个数大于或等于该第二SSB集合对应的最大发送个数。
图5是本发明实施例1的第一传输窗中的SSB的一示意图。如图5所示，在时间轴上周期性的设置有多个传输窗，一个周期T例如是40ms。第一传输窗是多个传输窗中的一个，对应于第一传输窗，第一SSB集合包含16个SSB，第二SSB集合包含8个SSB，而发送的SSB为其中的4个SSB，即X＝4。
在本实施例中，第二SSB集合中的SSB的个数还可以和最大发送个数X有关。例如，为了有足够的SSB发送机会以保证非授权频段的小区覆盖，第二SSB集合中的SSB的个数大于最大发送个数X。也就是说，该第二SSB集合中的至少一个SSB可以不在该第一传输窗中发送。
在本实施例中，该第二SSB集合或该第一SSB集合中的两个SSB是准共址(Quasi-collocation，QCL)的。也就是说，该第二SSB集合中或该第一SSB集合中，至少存在两个准共址的SSB。在本实施例中，如图2所示，该方法还可以包括：
步骤202：生成对应第一传输窗的第二SSB集合中的至少一个SSB。
在本实施例中，并不对步骤202和步骤201之间的关系进行限制。
例如，对应第一传输窗的第二SSB集合包含SSB1、SSB2、SSB3、SSB4这四个SSB，对于第一传输窗，通过步骤202生成SSB1、SSB2、SSB3、SSB4，在步骤201中发送SSB1和SSB4，不发送SSB2和SSB3，或者，发送SSB2和SSB3，不发送SSB1和SSB4。
又例如，对应第一传输窗的第二SSB集合包含SSB1、SSB2、SSB3、SSB4这四个SSB，对于第一传输窗，可以是先通过步骤202生成了SSB1，再在步骤201中发送该SSB1，然后再通过步骤202生成SSB2，再在步骤202中发送该SSB2。
又例如，对应第一传输窗的第二SSB集合包含SSB1、SSB2、SSB3、SSB4这四个SSB，但是在步骤202中只生成SSB1和SSB2，而不生成SSB3和SSB4。
在本实施例中，该第二SSB集合是预定义或预配置的。
对于预定义的情况，该第二SSB集合所包含的SSB是标准中基于第一SSB集合定义的。
这里，预定义是指标准中定义第二SSB集合包含的SSB的个数、时域位置以及 准共址关系中的至少一个。第二SSB集合例如是根据非授权频段监管要求定义的，以尽可能公平地共享频谱资源。
例如，第二SSB集合和频段(或频率范围)和/或子载波间隔(sub-carrier spacing,SCS)相关，即针对不同频段(或频率范围)和/或子载波间隔分别定义相应的第二SSB集合。
以频段为例，例如，针对频段F1～F2kHz，第二SSB集合包括SSB1和SSB2，针对频段F3～F4kHz，第二SSB集合包括SSB1、SSB2、SSB3和SSB4。对于其他频段，可以进行类似的设定。对于预配置的情况，如图2所示，该方法还可以包括：
步骤203：发送第一指示信息；该第一指示信息指示该第二SSB集合。
例如，在步骤201和步骤202之前，执行该步骤203，即，网络设备预先配置第二SSB集合并告知UE第二SSB集合。
在本实施例中，该第一指示信息可以通过高层信令或物理层指令发送。
例如，该高层信令是RRC信令或MAC CE。
在本实施例中，该第一指示信息对应第一参数或第二参数，该第一参数为已有参数，该第二参数为新的参数。也就是说，该第一指示信息使用第一参数或第二参数。
在本实施例中，该已有参数是Rel-15NR中RRC信令已经支持的IE(information element)。使用(或称为重用)已有参数是指采用与已有参数具有相同名称的参数，其指代的信息和/或指示的方法可以根据实际情况而不同，例如，针对授权频段和非授权频段，该已有参数指代的信息和/或指示的方法不同。
在本实施例中，使用新的参数是指使用新引入的参数IE。
例如，对于通过RRC信令发送第一指示信息的情况，可以使用已有参数，例如ssb-PositionsInBurst进行指示，或者，也可以使用新的参数，例如ssb-PositionsinBurst-NRU进行指示。
例如，针对授权频段，ssb-PositionsInBurst指示包括发送的SSB所构成的一个集合；针对非授权频段，ssb-PositionsInBurst(新参数，例如ssb-PositionsinBurst-NRU)指示上述第二SSB集合(candidate SSB的集合)。
再例如，针对非授权频段，ssb-PositionsInBurst(新参数，例如ssb-PositionsinBurst-NRU)指示该第二SSB集合中发送的SSB取决于信道接入，或者，取决于信道接入和上述最大发送个数SSB；而针对授权频段，不用取决于信道接 入或上述最大发送个数SSB。
再例如，针对授权频段，ssb-PositionsInBurst指示的一个SSB集合中的SSB的时域位置不能交叠；针对非授权频段，ssb-PositionsInBurst(新参数，例如ssb-PositionsinBurst-NRU)指示的一个SSB集合中的SSB的时域位置可以交叠。
再例如，针对Rel-15，针对Rel-15，ssb-PositionsInBurst指示包括发送的SSB所构成的一个集合；针对Rel-16或后续其他版本，ssb-PositionsInBurst(新参数，例如ssb-PositionsinBurst-NRU)指示上述第二SSB集合(candidate SSB的集合)。
再例如，针对Rel-15，ssb-PositionsInBurst(新参数，例如ssb-PositionsinBurst-NRU)指示该第二SSB集合中发送的SSB取决于信道接入，或者，取决于信道接入和上述最大发送个数SSB；针对Rel-16或后续其他版本，不用取决于信道接入或上述最大发送个数SSB。
再例如，针对Rel-15，ssb-PositionsInBurst指示的一个SSB集合中的SSB的时域位置不能交叠；针对Rel-16或后续其他版本，ssb-PositionsInBurst(新参数，例如ssb-PositionsinBurst-NRU)指示的一个SSB集合中的SSB的时域位置可以交叠。
在本实施例中，该第一指示信息可以直接指示第二SSB集合。
例如，通过比特图(bit-map)指示第一SSB集合中的哪些SSB属于第二SSB集合，或者，指示的第二SSB集合中的SSB个数、起始位置以及结束位置。
例如，该第一指示信息包含N个比特，其与第一SSB集合中的各个SSB一一对应。1表示对应的SSB是第二SSB集合中的SSB，0表示对应的SSB不是第二SSB集合中的SSB。
图6是本发明实施例1的指示第二SSB集合的一示意图。如图6所示，该第一指示信息包含16个比特，依次为1111110000000000，则第一SSB集合中的与“1”对应的SSB为第二SSB集合中的SSB。
又例如，第一SSB集合被分为M组，该第一指示信息包含M个比特，其与第一SSB集合中的各组SSB一一对应。1表示对应的组中的SSB是第二SSB集合中的SSB，0表示对应的组中的SSB不是第二SSB集合中的SSB。
在本实施例中，该第一指示信息也可以基于该第一SSB集合中的SSB的时域位置，和/或，该第一SSB集合中的SSB的准共址关系，指示该第二SSB集合。
例如，该第一指示信息基于该第一SSB集合中的SSB与第一索引的对应关系， 指示该第二SSB集合；该第一索引表示该第一SSB集合中的SSB在该一个传输窗中的时域位置，该第一SSB集合中的SSB与该第一索引的取值一一对应。
又例如，该第一指示信息基于指示该第一SSB集合中的SSB与第二索引的对应关系，指示该第二SSB集合；该第二索引表示该第一SSB集合中的SSB之间的准共址关系，或者说，该第二索引表示第一SSB集合中的SSB对应的空域信息(例如，波束标识)，第一SSB集合中对应相同第二索引的SSB是准共址的。该第一SSB集合包括两个对应相同的第二索引取值的SSB。在本实施例中，该两个对应相同第二索引取值的SSB是准共址的。
例如，第二索引具有Y个取值，该第一指示信息包括Y个比特，其与第二索引的各个取值一一对应。1表示对应的第二索引所对应的SSB是第二SSB集合中的SSB，0表示对应的第二索引所对应的SSB不是第二SSB集合中的SSB。
图7是本发明实施例1的指示第二SSB集合的另一示意图。如图7所示，该第一指示信息包含4个比特，依次为1100，第二索引具有4个取值，依次为0123，第一SSB集合包含16个SSB，其对应的第二索引依次为0123012301230123，则与1对应的第二索引(数值为0和1)所对应的SSB是第二SSB集合中的SSB。
又例如，第一索引或第二索引被分为Y组，该第一指示信息包含Y个比特，其与第一索引或第二索引的各组一一对应。1表示对应的第一索引或第二索引的组所对应的SSB是第二SSB集合中的SSB，0表示对应的第一索引或第二索引的组所对应的SSB不是第二SSB集合中的SSB。
在本实施例中，该第一指示信息还基于该第一SSB集合中的SSB与第三索引的对应关系，指示该第二SSB集合；该第三索引表示该第一SSB集合中对应相同的第二索引取值的SSB构成的组中的SSB在该组中的序号或时域位置，该组中的SSB与该第三索引的取值一一对应。
例如，第二索引具有Y个取值，具有相同的第二索引取值的SSB构成了Y个组，第一指示信息包括2Y个比特，其中，前Y个比特指示与某一第二索引取值对应的SSB是否为第二SSB集合中的SSB，后Y个比特指示与某一第三索引取值对应的SSB是否为第二SSB集合中的SSB。
图8是本发明实施例1的指示第二SSB集合的另一示意图。如图8所示，该第一指示信息包含8个比特，依次为11000110，第二索引具有4个取值，依次为0123， 具有相同的第二索引取值的SSB构成了4个组，第一SSB集合包含16个SSB，其对应的第二索引依次为0123012301230123，对应的第三索引依次为0000111122223333，则第一指示信息的前4个比特中的1对应的第二索引取值为0和1，后4个比特中的1对应的组的序号为1和2。
在本实施例中，第一SSB集合中的SSB可以对应于一个第二索引，也可以对应于多个第二索引。
当一个SSB对应于多个第二索引时，可以根据SSB与多个第二索引的对应关系，指示该第二SSB集合。
图9是本发明实施例1的指示第二SSB集合的另一示意图。如图9所示，该第一指示信息包含4个比特，依次为1100，第一SSB集合中的SSB对应于两个第二索引，记为第二索引1和第二索引2，第二索引1具有4个取值，分别为0123，第二索引2也具有4个取值，分别为3012，则与1对应的第二索引1(取值为0和1)和第二索引2(取值为3和0)所对应的SSB都是第二SSB集合中的SSB。
在本实施例中，通过上述步骤203指示了第二SSB集合，即第二SSB集合中的SSB的时域位置，另外，还可以进一步指示第二SSB集合中的SSB之间的准共址关系。
如图2所示，该方法还可以包括：
步骤204：发送第二指示信息；该第二指示信息指示该第二SSB集合中的SSB之间的准共址关系。
通过步骤204，UE可以确定第二SSB集合中的各个SSB之间的准共址关系。
在本实施例中，步骤203和步骤204可以先后执行，也可以同时执行，本发明实施例不对其时序进行限制。
另外，当UE没有收到该第二指示信息时(包括网络设备未发送，以及网络设备发送但UE未收到)，由于第二SSB集合是第一SSB集合或者是第一SSB集合的真子集，也可以根据预定义的第一SSB集合中的SSB之间的准共址关系获知(确定)第二SSB集合中的各个SSB之间的准共址关系。
例如，根据预定义的第一SSB集合中的SSB与第二索引的对应关系获知第二SSB集合中的各个SSB之间的准共址关系。
例如，预定义的第一SSB集合中的任一SSB只对应一个第二索引取值，则对应 相同的第二索引取值的SSB之间是准共址的，对应不同的第二索引取值的SSB之间不是准共址的。第二SSB集合中的SSB之间的准共址关系与第一SSB集合中的相应SSB之间的准共址关系相同。
再例如，预定义的第一SSB集合中的至少一个SSB对应两个或两个以上第二索引取值，则对应的至少一个第二索引取值相同的SSB之间是可能是准共址的，对应的任一第二索引取值都不同的SSB之间不是准共址的。第二SSB集合中的SSB之间的准共址关系与第一SSB集合中的相应SSB之间的准共址关系相同。
在本实施例中，该第二指示信息可以进一步指示基于预定义的第一SSB集合中的SSB之间的准共址关系不是准共址的SSB(对应的任一第二索引取值均不同的SSB)是准共址的，或者，该第二指示信息可以进一步指示基于该预定义的准共址关系可能准共址的SSB(对应的至少一个第二索引取值相同的SSB)是准共址的。
例如，根据预定义的第一SSB集合中的SSB与第二索引的对应关系，第一SSB和第二SSB不是准共址的(对应的任一第二索引取值均不同)，而该第二指示信息可以指示第二SSB集合中的第一SSB与第二SSB是准共址的。则UE接收到第二指示信息后，可根据第二指示信息确定第一SSB和第二SSB是准共址的。
再例如，根据预定义的第一SSB集合中的SSB与第二索引的对应关系，第一SSB和第二SSB可能是准共址的(对应至少一个相同的第二索引取值的SSB)，而该第二指示信息可以指示第二SSB集合中的第一SSB与第二SSB是准共址的。则UE接收到第二指示信息后，可根据第二指示信息确定第一SSB和第二SSB是准共址的。
在本实施例中，可以通过复用第一指示信息指示第二指示信息，或者说通过第一指示信息隐式指示第二指示信息。
图10是本发明实施例1的指示第二SSB集合的SSB之间的准共址关系的一示意图。如图10所示，第一SSB集合中的SSB对应于第二索引1和第二索引2，可以通过第二索引2的取值来隐式的指示第二SSB集合中的SSB之间的准共址关系，即具有相同第二索引2取值的SSB之间是准共址的。
一般地，第二指示信息不能指示基于预定义的第一SSB集合中的SSB之间的准共址关系是准共址的SSB不是准共址的。若UE接收到第二指示信息指示基于预定义的第一SSB集合中的SSB之间的准共址关系是准共址的SSB不是准共址的，UE仍根据预定义的第一SSB集合中的SSB之间的准共址关系确定第二SSB集合中的 SSB之间的准共址关系。
例如，根据预定义的第一SSB集合中的SSB与第二索引的对应关系，第一SSB和第二SSB是准共址的(分别对应一个第二索引取值且相同)，而该第二指示信息指示第二SSB集合中的第一SSB与第二SSB不是准共址的，则根据预定义的第一SSB集合中的SSB之间的准共址关系，UE仍认为第一SSB和第二SSB是准共址的。
为便于说明，以下假设第四索引表示第二SSB集合中的SSB的空域信息(例如，波束标识)，或者说，表示第二SSB集合中的各个SSB之间的准共址关系，具有相同的第四索引取值的SSB是准共址的。
另外，如图10中的示例，在第一SSB集合中的SSB对应于两个或更多个第二索引的情况下，也可以通过其中的一个第二索引来表示第二SSB集合中的SSB的空域信息，或者说，表示第二SSB集合中的各个SSB之间的准共址关系，具有相同的该第二索引取值的SSB是准共址的。
图11是本发明实施例1的指示第二SSB集合的SSB之间的准共址关系的另一示意图。如图11所示，其第二索引以及第三索引与图8所示的相同，第二SSB集合中的SSB对应的第四索引依次为01010101，第二SSB集合中的SSB之间的准共址关系如图11所示，具有相同的第四索引取值的SSB之间是准共址的。
在本实施例中，若第二SSB集合中的至少一个SSB对应两个或两个以上第二索引(或者第四索引)取值，UE需要根据接收到的各SSB中指示的第二索引(或者第四索引)取值唯一确定其接收到的第二SSB集合中的SSB之间的QCL关系。
在本实施例中，第一SSB集合是预定义的。
例如，第一SSB集合中的一个SSB可以对应于一个第一索引取值，也可以对应于至少一个第二索引取值，也可以同时对应于一个第一索引以及至少一个第二索引取值。
在本实施例中，第一SSB集合中的各个SSB对应于一个第一索引取值。该第一索引表示该第一SSB集合中的SSB在该一个传输窗中的时域位置，该第一SSB集合中的SSB与该第一索引的取值一一对应。
UE可以根据第一索引确定第一SSB集合中的SSB的时域位置，从而获取帧定时。
在本实施例中，第一SSB集合中的各个SSB也可以对应于至少一个第二索引。 该第二索引表示该第一SSB集合中的SSB之间的准共址关系，该第一SSB集合包括两个对应相同的第二索引取值的SSB。
在本实施例中，第一SSB集合中的各个SSB可以对应于一个第二索引，也可以对应于多个第二索引。
UE可以根据第二索引确定第一SSB集合中的各个SSB之间的空域信息，即准共址关系。
在本实施例中，可以对第一SSB集合中的SSB的第一索引和/或第二索引进行指示。例如，可以通过SSB中的信号和/或信道指示。
图12是本发明实施例1的SSB的一结构示意图。如图12所示，一个SSB中包含PBCH、SSS、PBCH以及PSS。
为了支持UE接收到一个SSB后能够根据该SSB确定帧定时，需要通过该SSB中的信号和/或信道(例如，PSS、SSS、PBCH和PBCH DMRS中的指示一个)指示该SSB在相应传输窗里的时域位置。
例如，该SSB在相应传输窗里的时域位置通过第一索引表征(第一索引取值与第一SSB集合中的SSB一一对应)，通过该SSB中的信号和/或信道指示该SSB对应的第一索引取值，从而指示该SSB在相应传输窗里的时域位置。
具体地，例如，通过SSB中的DMRS指示第一索引取值的一部分信息，通过SSB中的PBCH中的一部分payload指示第一索引取值的另一部分信息，例如下表所示。
Figure PCTCN2019071488-appb-000001
再例如，该SSB在相应传输窗里的时域位置通过第二索引及其他信息(第三索引或定时偏差)表征，通过该SSB中的信号和/或信道指示该SSB对应的第二索引及其他信息，从而指示该SSB在相应传输窗里的时域位置。
具体地，例如，通过SSB中的DMRS指示第二索引的取值，通过SSB中的PBCH中的一部分payload指示其他信息。另外，当第一SSB集合中的各个SSB对应于一个第一索引取值时，还可以通过指示的第一索引以及第一索引和第二索引的对应关系来确定相应的第二索引；当第一SSB集合中的各个SSB对应于至少一个第二索引时， 还可以通过指示的第二索引以及第二索引和第一索引的对应关系来确定相应的第一索引。
在本实施例中，第一索引例如是SSB时间索引(SSB time index)或SSB索引(SSB index)。
在本实施例中，第二索引例如是SSB波束索引(SSB beam index)或SSB索引(SSB index)或DRS索引(DRS index)或定时偏差(timing offset)。
图13是本发明实施例1的第一SSB集合的一示意图。如图13所示，第一索引为SSB索引，第二索引为SSB波束索引，第一SSB集合包含16个SSB，这16个SSB分别对应于一个SSB索引和一个SSB波束索引，其中，具有相同的第二索引取值的SSB为不相邻的SSB。
图14是本发明实施例1的第一SSB集合的另一示意图。如图14所示，第一索引为SSB索引，第二索引为SSB波束索引，第一SSB集合包含16个SSB，这16个SSB分别对应于一个SSB索引和一个SSB波束索引，其中，具有相同的第二索引取值的SSB为相邻的SSB。
图15是本发明实施例1的第一SSB集合的另一示意图。如图15所示，第一索引为SSB时间索引，第二索引为SSB索引，第一SSB集合包含16个SSB，这16个SSB分别对应于一个SSB时间索引和一个SSB索引，其中，具有相同的第二索引取值的SSB为不相邻的SSB。
图16是本发明实施例1的第一SSB集合的另一示意图。如图16所示，第一索引为SSB时间索引，第二索引为SSB索引，第一SSB集合包含16个SSB，这16个SSB分别对应于一个SSB时间索引和一个SSB索引，其中，具有相同的第二索引取值的SSB为相邻的SSB。
图17是本发明实施例1的第一SSB集合的另一示意图。如图17所示，第一索引为SSB时间索引，第二索引为SSB波束索引，第一SSB集合包含16个SSB，这16个SSB分别对应于一个SSB索引和一个SSB波束索引，其中，具有相同的第二索引取值的SSB为不相邻的SSB。
图18是本发明实施例1的第一SSB集合的另一示意图。如图18所示，第一索引为SSB时间索引，第二索引为SSB波束索引，第一SSB集合包含16个SSB，这16个SSB分别对应于一个SSB索引和一个SSB波束索引，其中，具有相同的第二索 引取值的SSB为相邻的SSB。
在本实施例中，例如，在非授权频段中，SSB也可能作为DRS的一部分发送。在该情况下，DRS与SSB是一一对应的。
例如，在该情况下，传输窗可以是DRS传输窗，第二索引可以是DRS索引。
也就是说，一个DRS包含一个SSB，另外，一个DRS还可以包含至少一个剩余最小化系统信息(Remaining Minimum System Information，RMSI)或者SIB1对应的PDCCH和/或PDSCH，此时，DRS中的SSB与RMSI一一对应。
图25是本发明实施例1的DRS的结构的一示意图。如图25中的(a)所示，该DRS内包含重复的两个SSB；如图25中的(b)所示，该DRS包含扩展的一个SSB。
图25仅是DRS结构的示意性附图，DRS也可以使用其他的结构。
当SSB包含在DRS中发送时，针对SSB描述的上述方法也适用于DRS，此处不再重复说明。

实施例2
本发明实施例提供了一种数据传输方法，该方法应用于用户设备侧，其对应与实施例1所述的应用于网络设备侧的数据传输方法，相同的内容不再重复说明。
图19是本发明实施例2的数据传输方法的一示意图。如图19所示，该方法包括：
步骤1901：根据第二SSB集合中的SSB的时域位置和/或SSB之间的准共址关系，接收下行信号和/或信道或发送上行信号和/或信道，
该第二SSB集合是第一SSB集合的子集，所述第一SSB集合中的各个SSB对应于一个传输窗的不同时域位置。
这样，UE可以根据第二SSB集合中的SSB的时域位置和/或准共址关系，接收下行信号和/或信道或发送上行信号和/或信道，从而能够提高资源利用的灵活性和利用率。
在本实施例中，第一SSB集合可以是预定义的。
在本实施例中，第二SSB集合可以是预定义或者预配置的。
在本实施例中，第二SSB集合以及第一SSB集合的内容以及指示的方法可以与 实施例1中的记载相同，此处不再重复说明。
在本实施例中，如图19所示，该方法还可以包括：
步骤1902：确定第二SSB集合中的SSB的时域位置和/或准共址关系。
例如，根据第一SSB集合中的SSB的时域位置和/或SSB之间的准共址关系，确定第二SSB集合中的SSB的时域位置和/或SSB之间的准共址关系。
在本实施例中，第一SSB集合中的SSB的时域位置和/或SSB之间的准共址关系是预定义的，其预定义方式与实施例1中的记载相同，此处不再重复说明。
例如，若接收到第一指示信息和/或第二指示信息，还根据接收的第一指示信息和/或第二指示信息，确定第二SSB集合中的SSB的时域位置和/或准共址关系，该第一指示信息指示该第二SSB集合，该第二指示信息指示该第二SSB集合中的SSB之间的准共址关系。
在本实施例中，第一指示信息和/或第二指示信息的内容以及网络设备发送该信息的方法与实施例1中的记载相同，此处不再重复说明。
例如，根据第二索引和/或接收的第二指示信息，确定第二SSB集合中的SSB之间的准共址关系，该第二索引表示该第一SSB集合中的SSB之间的准共址关系。
例如，如前面的图11所示，根据第二索引以及第二指示信息中的第四索引，确定第二SSB集合中的SSB之间的准共址关系。
另外，也可以仅根据第四索引确定第二SSB集合中的SSB之间的准共址关系。
在步骤1901中，根据第二SSB集合中的SSB的时域位置和/或准共址关系，接收下行信号和/或信道或发送上行信号和/或信道。
在本实施例中，该下行信号和/或信道例如是SSB/DRS，或者，SSB/DRS以外的下行信号和/或信道，SSB/DRS以外的下行信号和/或信道例如物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行数据信道(Physical Downlink Shared Channel，PDSCH)和下行参考信号(例如CSI-RS)中的至少一个。
在本实施例中，该上行信号和/或信道例如是物理随机接入信道(Physical Random Access Channel，PRACH)、上行参考信号(例如探测参考信号(Sounding Reference Signal，SRS))、物理上行控制信道(Physical Uplink Control Channel，PUCCH)和物理上行数据信道(Physical Uplink Shared Channel，PUSCH)中的至少一个。
在步骤1901中，可以根据第二SSB集合中的SSB的时域位置和/或准共址关系， 进行以下的至少一种处理：监听物理下行控制信道；接收物理下行数据信道；发送上行信号和/或信道；以及进行无线链路监听(Radio Link Monitoring，RLM)。
例如，对于根据第二SSB集合中的SSB的时域位置和/或准共址关系，监听PDCCH或接收PDSCH的情况，其中，可以根据第二SSB集合中的SSB时域位置和/或SSB之间QCL关系获知PDCCH与第二SSB集合中的SSB的QCL关系，还可以根据第二索引和/或接收的第二指示信息，确定第二SSB集合中的SSB和该PDCCH以及该PDSCH中的至少一个之间的准共址关系，从而监听PDCCH或接收PDSCH。
例如，对于监听PDCCH的情况，当与PDCCH的DMRS天线端口(DMRS antenna port)和第二SSB集合中的SSB是准共址的时，UE根据第二索引和/或第四索引确定与PDCCH的DRMS antenna port准共址的第二SSB集合中的SSB，从而接收该PDCCH。例如，包含该PDCCH的CORESET配置了传输配置指示(Transmission Configuration Indication，TCI)状态，该TCI状态对应的TCI state ID对应一个第二索引和/或第四索引，则与该PDCCH的DMRS antenna port是与该第二索引和/或第四索引对应的第二SSB集合中的SSB。
再例如，对于监听对应系统信息(SI)的PDCCH的情况，UE根据第二SSB集合中的SSB时域位置和/或QCL关系获知对应系统信息的PDCCH monitoring occasion与第二SSB集合中的SSB的对应关系，从而监听对应系统信息的PDCCH。其中，第二SSB集合中QCL的SSB对应的PDCCH monitoring occasion相同。例如，第二SSB集合中包括第一SSB和第二SSB，并且第一SSB和第二SSB是QCL的，则第一SSB和第二SSB对应的PDCCH monitoring occasion相同。
以下是对应SI的PDCCH monitoring occasion与第二SSB集合中的SSB的对应关系的一个具体示例。
例如，SI-window中第[x*N+K]个对应SI的PDCCH monitoring occasion(s)和第二SSB集合中第K组QCL的SSB是对应的，其中，x＝0,1,...X-1,K＝1,2,…N,N是第二SSB集合中的QCL的SSB的组数，X＝‘CEIL(SI-window中对应系统消息的PDCCH monitoring occasion(s)的个数/N’)。
图26是本发明实施例2的对应SI的PDCCH monitoring occasion与第二SSB集合中的SSB的对应关系的一示意图。
如图26所示，假设，N＝2，SI-window中对应系统消息的PDCCH monitoring  occasion(s)的个数＝8，对应SI的PDCCH monitoring occasion与第二SSB集合中的SSB的对应关系如图26所示。
例如，对于接收PDSCH的情况，当PDCCH不指示TCI状态时，UE假设与PDSCH的DRMS antenna port准共址的第二SSB集合中的SSB与该PDSCH关联的PDCCH相同；或者，与该PDSCH关联的PDCCH指示PDSCH的TCI状态(例如DCI中包括TCI state ID)，该TCI state对应的TCI state ID对应一个第二索引和/或第四索引，则与该PDSCH的DMRS antenna port准共址的是与该第二索引和/或第四索引对应的第二SSB集合中的SSB。
例如，对于发送PRACH的情况，UE根据第二SSB集合中的SSB之间的准共址关系确定SSB与PRACH之间的关联关系，从而选择PRACH资源发送消息1(msg.1)。
由上述实施例可知，UE可以根据第二SSB集合中的SSB的时域位置和/或准共址关系，接收下行信号和/或信道或发送上行信号和/或信道，从而能够提高资源利用的灵活性和利用率。

其中，该第二SSB集合是第一SSB集合的子集，该第一SSB集合中的各个SSB对应于该第一传输窗的不同时域位置。
在本实施例中，步骤2001、2002、2003、2005并不是必要的步骤。
另外，不对步骤2001～2004之间的时序关系进行限制。
在本实施例中，可以执行步骤2006和步骤2007中的至少一个。
在本实施例中，步骤2001～2007的具体实现方法与实施例1和实施例2中的记载相同，此处不再重复说明。
