Description

物理下行控制信道重复传输方法、装置及用户设备
本申请要求于2021年4月2日提交国家知识产权局、申请号为202110363014.X、申请名称为“物理下行控制信道重复传输方法、装置及用户设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请属于通信技术领域，具体涉及一种物理下行控制信道PDCCH重复传输方法、装置及用户设备。
背景技术
为了提高PDCCH的传输性能，5G NR在标注(release)17中引入了PDCCH重复传输方案，不同重复传输机会(occasion)可以来自不同的发送接收点TRP，当其中一个TRP发送阻塞时，另一个TRP上的PDCCH传输还能被终端接收到，进而提升PDCCH可靠性。终端在检测重复发送的PDCCH时，会采用不用的接收机算法，例如终端除了尝试在每个PDCCH重复传输时机occasion上解调PDCCH外，还会把所有occasion上的软比特信息进行合并，多做一次译码。不同的接收机算法会影响盲检次数，进而影响overbooking计算规则。为了保证收发理解一致，终端可能会想基站上报解调行为以及盲检假设的次数。另外，当PDCCH携带BWP切换指示信令时，切换起始时间通常会参考PDCCH所在的时隙，但是PDCCH采用重复发送后，终端成功检测PDCCH的时间会增加，因此切换时间也需要重新设计。除此之外，终端会收到携带BWP切换指示信令或者半持续PDSCH调度释放信令的PDCCH时，会在PDCCH结束N个符号后给基站上报PDCCH译码的响应混合自动重传请求确认(Hybrid Automatic RepeatreQuest-ACK，HARQ-ACK)，当PDCCH采用重复传输时，参考PDCCH candidate需要重新定义。最后PDCCH重复传输在一些调度场景，可能会打破现有的调度规则，例如被调度的PDSCH是否可以早于PDCCH重复传输在时域上较晚的那个candidate也需要考虑确定一些规则才能被支持。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
以下将对本申请实施例涉及的术语进行说明。
1、控制资源集(CORESET)
在新空口(New Radio，NR)***中，下行控制信令引入了CORESET，一个CORESET定义了下行信道(例如物理下行控制信道(Physical Downlink Control Channel，PDCCH))可能占用的频域资源位置和连续的时域资源。
2、搜索空间(search space)
在NR***中，search space用于指示用户设备(user equipment，UE)在时域资源上的某些监听机会monitoring occasion(和对应monitoring occasion上的某些PDCCH候选candidate)去监听PDCCH。
3、盲检测(Blind Decoding，BD)
在NR***中，由于在网络侧设备为UE配置PDCCH传输之后，UE可能并不能确定PDCCH占用的控制信道单元(Control Channel Element，CCE)数目大小、位置等，因此，UE需要根据网络侧设备配置的至少一个CORESET和至少两个搜索空间(一个CORESET关联两个搜索空间)，确定多个PDCCH candidate，并对每个PDCCH candidate进行解码，以接收PDCCH上承载的信息。
4、盲检测能力
盲检测能力信息为：UE向网络侧设备上报的能力信息，该盲检测能力信息可以包括以下任一项：UE的最大盲检测次数、UE是否支持执行软比特合并的能力。
5、UE的最大盲检测次数

6、BWP切换过程
若UE在一个slot接收到PDCCH上承载的下行链路控制信息DCI，并且该DCI中携带BWP切换指示信令，则UE可以根据该BWP切换指示信令，从该一个slot的起始传输时刻起的BWP切换预留时间(T BWPswitchDelay)个slot之后，切换到新的BWP上。在从该一个slot的起始传输时刻起，到UE切换到新的BWP的时刻间，UE不能接收或发送任何信号。
7、其他术语
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的PDCCH重复传输进行详细地说明。
图2示出了本申请实施例提供的一种PDCCH重复传输的流程图。如图2所示，本申请实施例提供的PDCCH重复传输可以包括下述的步骤101和步骤102(或步骤103)。
步骤101、在PDCCH重复传输装置接收到重复传输的PDCCH的情况下，PDCCH重复传输装置确定重复传输的X个PDCCH候选。
本申请实施例中，X为大于1的整数。
可选地，本申请实施例中，PDCCH重复传输装置可以从网络侧设备接收高层信令，该高层信令包括无线资源控制(Radio Resource Control，RRC)信令，该RRC信令中包括网络侧设备为PDCCH重复传输装置配置的CORESET和至少两个搜索空间，从而PDCCH重复传输装置可以根据该CORESET组和该至少一个搜索空间，确定重复传输的X个PDCCH候选。
可选地，本申请实施例中，上述CORESET对应至少一个发送接收点(TransmissionReception Point，TRP)。
本申请实施例中，上述X个PDCCH候选对应的搜索空间相关联。
可选地，本申请实施例中，CORESET关联的至少两个搜索空间中的每个搜索空间、可以对应一个PDCCH候选。
可选地，本申请实施例中，在同一个传输单元中传输M个搜索空间关联组，每个搜索空间关联组中包括X个搜索空间，该X个搜索空间与X个PDCCH候选一一对应；
每个搜索空间关联组中有K个候选PDCCH集合，每个候选PDCCH集合包括X个PDCCH候选；
在同一传输单元中传输的候选PDCCH集合的总数为H；
其中，M的数值是由以下任一项确定的：预设的数值、网络侧设备基于PDCCH重复传输装置上报的能力确定的数值；K的数值是由以下任一项确定的：预设的数值、网络侧设备基于PDCCH重复传输装置上报的能力确定的数值；H的数值是由以下任一项确定的：预设的数值、网络侧设备基于PDCCH重复传输装置上报的能力确定的数值。
进一步可选地，本申请实施例中，上述传输单元可以包括以下任一项：时域传输符号(正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号)、时隙(slot)、微时隙(mini-slot)、子帧、无线帧等。
可选地，本申请实施例中，PDCCH重复传输装置可以根据CORESET和至少两个搜索空间，确定X个PDCCH候选。
需要说明的是，针对PDCCH重复传输装置根据CORESET和搜索空间确定PDCCH的说明，可以参考相关技术中的具体描述，本申请实施例在此不予赘述。
步骤102、PDCCH重复传输装置基于X个PDCCH候选假设的第一盲检测次数，执行超额预定规则。
可以理解的是，PDCCH重复传输装置基于X个PDCCH候选假设的第一盲检测次数执行超额预定规则，也可以认为是PDCCH重复传输装置基于overbooking规则，确定重复传输的PDCCH的盲检测次数。
步骤103、PDCCH重复传输装置根据目标PDCCH候选的时域资源，执行目标操作。
本申请实施例中，上述目标PDCCH候选为：该X个PDCCH候选中，满足预定条件的PDCCH候选。
可选地，本申请实施例中，上述预设条件可以包括以下至少一项：
时域资源上的最后一个PDCCH候选；
时域资源上的第一个PDCCH候选；
关联的搜索空间的索引值最大的PDCCH候选；
关联的搜索空间的索引值最小的PDCCH候选；
关联的控制资源集的索引值最大的PDCCH候选；
关联的控制资源集的索引值最小的PDCCH候选。
可选地，本申请实施例中，上述目标操作可以包括以下任一项：BWP切换、发送确定信息、确定其他传输的调度图案。
本申请实施例提供的PDCCH重复传输方法，在PDCCH重复传输装置接收到重复传输的PDCCH的情况下，PDCCH重复传输装置可以确定X个PDCCH候选，该X个PDCCH候选对应的搜索空间相关联，基于X个PDCCH候选假设的第一盲检测次数，执行超额预定规则；或，PDCCH重复传输装置根据目标PDCCH候选的时域资源，执行目标操作。由于PDCCH重复传输装置可以基于X个PDCCH候选假设的第一盲检测次数，执行超额预定规则，以避免出现对该X个PDCCH候选进行盲检测的次数，超出PDCCH重复传输装置的最大盲检测次数的情况，因此，可以提升PDCCH重复传输装置进行盲检测的可靠性；或者，由于PDCCH重复传输装置可以根据X个PDCCH候选中，满足预定条件的PDCCH候选的时域资源，执行目标操作，以避免出现PDCCH重复传输装置无法确定从哪个时刻起的预留时间之后，执行目标操作的情况，因此，可以提升执行操作的 可靠性。如此，可以提升PDCCH重复传输装置执行操作的可靠性。
可选地，本申请实施例中，上述第一盲检测次数由以下任一项确定：
默认假设的解调重复传输的PDCCH的盲检测次数；
PDCCH重复传输装置上报的解调重复传输的PDCCH的盲检测次数；
网络侧设备基于PDCCH重复传输装置上报的解调重复传输的PDCCH的盲检测次数，确定的盲检测次数。
进一步可选地，本申请实施例中，在第一盲检测次数由网络侧设备基于PDCCH重复传输装置上报的解调重复传输的PDCCH的盲检测次数，确定的盲检测次数确定的情况下，PDDCH重复传输装置可以向网络侧设备上报解调重复传输的PDCCH的盲检测次数，这样，网络侧设备可以根据上报的解调重复传输的PDCCH的盲检测次数，重新确定一个盲检测次数，以使得PDCCH重复传输装置可以按照重新确定的一个盲检测次数，执行超额预定规则。
可以理解，当PDCCH重复传输装置被配置了PDCCH重复传输repetition时，该PDCCH repetition通过至少两个PDCCH候选发送。基于默认假设的解调PDCCH repetition能力或者PDCCH重复传输装置上报解调PDCCH repetition的能力去执行overbooking规则。
其中，默认假设的盲检测BD数量可以是2或者3；PDCCH重复传输装置上报解调PDCCH repetition的能力(该能力包括BD的数量或者和是否执行软比特合并的能力)。
其中，即使当PDCCH重复传输装置上报一个盲检测次数时，网络侧设备可以通过信令指示PDCCH重复传输装置执行overbooking规则按照另一个盲检测次数假设；其中该另一个盲检测次数小于或等于该一个盲检测次数。
下面将举例说明PDCCH重复传输装置是如何基于X个PDCCH候选假设的第一盲检测次数，执行超额预定规则的。
可选地，本申请实施例中，上述步骤102具体可以通过下述的步骤102a实现。
步骤102a、PDCCH重复传输装置按照预定规则，基于第一盲检测次数，执行超额预定规则。
可选地，在申请实施例的一种可能的实现方式中，上述预定规则包括以下任一项：
X个PDCCH候选中的每个PDCCH候选关联不同搜索空间；
索引值小的搜索空间关联的PDCCH候选按照第三盲检测次数计算，索引值大的搜索空间关联的PDCCH候选按照第四盲检测次数计算；
其中，第四盲检测次数大于或等于第三盲检测次数。
进一步可选地，本申请实施例中，上述索引值具体可以为ID值。
示例性地，当PDCCH repetition按照3次BD假设时，当PDCCH重复次数为2、且每个PDCCH候选和不同搜索控件关联时，其中小的搜索空间ID关联的PDCCH候选按照1次BD计算，大的搜索空间ID关联的PDCCH候选按照2次BD计算。
可选地，本申请实施例中，若X个PDCCH候选中的每个PDCCH候选都在同一个传输单元中传输，且X个PDCCH候选在时域资源上不完全重叠，则：
索引值大的搜索空间关联的PDCCH候选的最后一个符号，晚于索引值小的搜索空间关联的PDCCH候选的最后一个符号；
或者，索引值大的搜索空间关联的PDCCH候选的第一个符号，晚于索引值小的搜索空间关联的PDCCH候选的第一个符号。
示例性地，当PDCCH repetition都在相同的传输单元(例如时隙)内，并且两个PDCCH候选在时域上不完全重叠时，则大的搜索空间ID关联的PDCCH候选的最后一个符号要晚于小的搜索空间ID关联的PDCCH候选的最后一个符号；或者，大的搜索空间ID关联的PDCCH候选的第一个符号要晚于小的搜索空间ID关联的PDCCH候选的第一个符号。
可选地，在申请实施例的另一种可能的实现方式中，上述预定规则包括以下任一项：
在第一盲检测次数等于X的情况下，每个PDCCH候选按照1次盲检测计算，若第X次盲检测超过PDCCH重复传输装置上报的盲检测能力，则重复传输的PDCCH按照X-1次盲检测计算；
在第一盲检测次数等于X的情况下，每个PDCCH候选按照1次盲检测计算，若第X次盲检测未超过PDCCH重复传输装置上报的盲检测能力，则重复传输的PDCCH按照X次盲检测计算，第X次盲检测为：将X个PDCCH候选对应的软比特信息进行合并，并对合并后的软比特信息进行的盲检测。
其中，对合并后的软比特信息所进行的盲检测关联第一搜索空间；该第一搜索空间为：预定的特定搜索空间，或网络侧设备配置的特定搜索空间；该第一搜索空间用于对合并后的软比特信息进行盲检测。
示例性地，当PDCCH repetition按照3次BD假设计算overbooking规则时，每个PDCCH候选按照1次BD计算。如果第3次BD未超过PDCCH重复传输装置上报的盲检测能力，则重复传输的PDCCH按照3次盲检测计算，第3次盲检测为：将X个PDCCH候选对应的软比特信息进行合并，并对合并后的软比特信息进行的盲检测。
其中，第一搜索空间可以是一个虚拟搜索空间，不通过高层信令指示。该第一搜索空间在overbooking规则中优先级按照最低假设。其中第一搜索空间上不统计CCE的盲检能力。
可选地，本申请实施例中，上述步骤102具体可以通过下述的步骤102b实现。
步骤102b、在X个PDCCH候选中的任一个PDCCH候选满足第一条件的情况下，PDCCH重复传输装置确定X个PDCCH候选的发送行为是重复发送行为，并基于X个PDCCH候选的假设的第一盲检测次数，执行超额预定规则。
本申请实施例中，第一条件为：任一个PDCCH候选的时频资源、与目标时频资源冲突。
可选地，本申请实施例中，上述目标时频资源包括以下任一项：同步信号块SSB的时频资源、高层配置的小区特定参考信号CRS的时频资源、用于指示其他物理下行共享信道PDSCH速率匹配的时频资源、高层配置的不能使用的时频资源。
可以理解，PDCCH重复传输装置还是假设PDCCH是重复发送的行为，且PDCCH重复传输装置的overbooking规则不受时频资源冲突的影响。
可选地，本申请实施例中，在上述步骤102之后，本申请实施例提供的PDCCH重复传输还可以包括下述的步骤201。
步骤201、在满足第二条件的情况下，PDCCH重复传输装置对X个PDCCH候选和Y个PDCCH候选进行监听。
其中，上述第二条件包括：PDCCH重复传输装置上报了目标能力，Y个PDCCH候选不用于PDCCH的重复传输，Y个PDCCH候选关联的接收波束beam不同，Y个PDCCH的时域资源发生重叠；目标能力为：PDCCH重复传输装置同时接收关联不同beam的PDCCH候选的能力。
可以理解的是，如果PDCCH重复传输装置上报了同时接收PDCCH repetition的能力，并且网络侧设备还配置了多个不是用于PDCCH repetition的Y个PDCCH候选，Y个PDCCH候选关联不同的QCL-typeD，且Y个PDCCH在时频资源上发生了重叠，则PDCCH重复传输装置可以同时监听X个PDCCH候选和Y个PDCCH候选。
下面将举例说明PDCCH重复传输装置是如何根据目标PDCCH候选的时域资源，执行BWP切换过程的。
PDCCH重复传输装置可以从网络侧设备接收PDCCH，如图3所示，若PDCCH携带了BWP切换指示信令，在现有NR通信***中，该PDCCH候选仅能在一个传输单元(对应一个时隙)的时域资源的前3个符号内发送，这样，PDCCH重复传输装置可以从一个传输单元的起始传输时刻起的预留时间(T BWPswitchDelay)之后，执行BWP切换过程。但是，在网络侧设备为PDCCH重复传输装置配置PDCCH重复传输的情况下，多个PDCCH候选可能并不是总在一个传输单元的时域资源的前3个符号内发送，这里的一个传输单元对应的是NR通信***中的一个时隙概念。终端可能联合多个PDCCH候选在时隙内最后一个PDCCH候选上通过软比特合并才能正确解出DCI信息，相比现有设计，延长了解DCI时间。为了保证终端在规定的时间内准确执行BWP切换(主要是PDCCH重复传输装置调整(Radio Frequency，RF)射频)，需要在参数T BWPswitchDelay基础上增加一个预设时间。
在本申请实施例中，在网络侧设备为PDCCH重复传输装置配置PDCCH重复传输的情况下，PDCCH重复传输装置可以根据BWP切换指示信令和一个PDCCH候选的时域资源，执行BWP切换过程，即PDCCH重复传输装置可以确定从一个PDCCH候选所在的传输单元的起始传输时刻起的预留时间之后，执行BWP切换过程，以解决上述相关技术中存在的问题。
可选地，本申请实施例中，在上述步骤103之前，本申请实施例提供的PDCCH重复传输还可以包括下述的步骤301，并且上述步骤103具体可以通过下述的步骤103a实现。
步骤301、PDCCH重复传输装置获取BWP切换指示信令。
进一步可选地，本申请实施例中，PDCCH重复传输装置可以对X个PDCCH候选进行盲检测，以获取BWP切换指示信令。
步骤103a、PDCCH重复传输装置根据BWP切换指示信令和目标PDCCH候选的时域资源，执行BWP切换过程。
本申请实施例中，上述目标PDCCH候选为：X个PDCCH候选中，时域资源上的最后一个PDCCH候选。
进一步可选地，本申请实施例中，PDCCH重复传输装置可以根据BWP切换指示信令，获取网络侧设备配置的预留时间(例如下述实施例中的预设切换预留时间)，并根据该预留时间和标PDCCH候选的时域资源，执行BWP切换过程。
以下将以四种不同的示例，举例说明PDCCH重复传输装置是如何根据预留时间和标PDCCH候选的时域资源，执行BWP切换过程的。
可选地，在本申请的一种可能的实现方式中，上述步骤103a具体可以通过下述的步骤103a1实现。
步骤103a1、PDCCH重复传输装置根据BWP切换指示信令和目标PDCCH候选的时域资源，从目标PDCCH候选所在的起始传输时刻起的第一时长之后，执行BWP切换过程。
本申请实施例中，上述第一时长包括：预设切换预留时间和预设时长。
可以理解，第一时长为：预设切换预留时间和预设时长之和。
进一步可选地，本申请实施例中，上述预设切换预留时间(T BWPswitchDelay)具体可以为：通信协议规定的预留时间。
具体地，本申请实施例中，在BWP切换过程发生在不同的小区上时，预设切换预留时间可以不同。
示例性地，如果BWP切换过程发生在辅小区(scell)上，则预设切换预留时间可以为辅小区休眠(scell domancy)场景下的规定时间。
进一步可选地，本申请实施例中，上述预设时长可以为：Z个slot，Z为正整数。
具体地，本申请实施例中，上述预设时长具体可以为：1个slot。
本申请实施例中，由于终端解调重复发送的PDCCH需要一定的时间，例如软比特合并会增加解码PDCCH时间，因此PDCCH重复传输装置可以从目标PDCCH候选(也就是时域资源上位置最靠后的PDCCH候选)所在的时隙的起始时间起，预留T BWPswitchDelay+Z个slot后，才能完成BWP切换。其中用于重复传输的多个PDCCH候选可以落在相同的slot内，或者占用不同的slot。
可选地，在本申请的另一种可能的实现方式中，上述步骤103a具体可以通过下述的步骤103a2实现。
步骤103a2、PDCCH重复传输装置根据BWP切换指示信令和目标PDCCH候选的时域资源，在X个PDCCH候选满足第三条件、且目标PDCCH候选在一个传输单元占用的时域资源超过第一门限值的情况下，从第一传输单元的起始传输时刻起的第一时长之后，执行BWP切换过程。
本申请实施例中，上述第一传输单元为：第二PDCCH候选所在的传输单元；第二PDCCH候选为：X个PDCCH候选中，时域资源上的第一个PDCCH候选。
可选地，本申请实施例中，上述第三条件为：X个PDCCH候选在同一个传输单元中传输。
进一步可选地，本申请实施例中，目标PDCCH候选在一个传输单元占用的时域资源具体可以为：符号。
进一步可选地，本申请实施例中，上述第一门限值具体可以为：通信协议规定的门限值。
具体地，本申请实施例中，上述第一门限值具体可以为：3。
可以理解，在X个PDCCH候选在同一个传输单元中传输(即当网络侧设备配置了intra-slot repetition传输)、且目标PDCCH候选在一个传输单元占用的符号超过3个符号的情况下，PDCCH重复传输装置可以从第一传输单元的起始传输时刻起的第一时长之后，执行BWP切换过程。
进一步可选地，本申请实施例中，上述“目标PDCCH候选在一个传输单元占用的符号超过第3个符号”可以理解为：目标PDCCH候选在时域资源上的第一个符号(或最后一个符号)，超过该目标PDCCH候选所在的传输单元的第3个符号。
举例说明，如图4所示，在网络侧设备配置了intra-slot repetition传输、且X个PDCCH候选(例如PDCCH候选1和PDCCH候选2)在同一个传输单元(例如slot#1)中传输的情况下，若PDCCH候选2在该slot#1占用的符号超过第3个符号，则PDCCH重复传输装置可以从第一传输单元(即slot#1)的起始传输时刻起的第一时长之后，执行BWP切换过程。
本申请实施例中，在X个PDCCH候选满足第三条件、且目标PDCCH候选在一个传输单元占用的时域资源超过第一门限值的情况下，由于可能会出现X个PDCCH候选中，时域资源上的第一个PDCCH候选上未盲检测出PDCCH的情况，因此，PDCCH重复传输装置可以从该第一个PDCCH候选所在的第一传输单元的起始传输时刻起的第一时长之后，即预设切换预留时间和预设时长之和的时长之后，才执行BWP切换过程。
可选地，在本申请的又一种可能的实现方式中，上述步骤103a具体可以通过下述的步骤103a3实现。
步骤103a3、PDCCH重复传输装置根据BWP切换指示信令和目标PDCCH候选的时域资源，在X个PDCCH候选满足第三条件、且目标PDCCH候选的第一时刻与第二PDCCH候选的第一时刻间的时间偏移量大于第二门限值的情况下，从第一传输单元的起始传输时刻起的第一时长之后，执行BWP切换过程。
本申请实施例中，上述第一时刻包括以下任一项：起始传输时刻、结束传输时刻。
可以理解，在X个PDCCH候选在同一个传输单元中传输(即当网络侧设备配置了跨时隙重复intra-slot repetition传输)、且目标PDCCH候选的起始传输时刻(或结束传输时刻)与第二PDCCH候选的起始传输时刻(或结束传输时刻)间的时间偏移量(offset)大于第二门限值的情况下，PDCCH重复传输装置可以从第一传输单元的起始传输时刻起的第一时长之后，执行BWP切换过程。
本申请实施例中，上述第二门限值为：PDCCH重复传输装置向网络侧设备上报的门限值。
进一步可选地，本申请实施例中，若X个PDCCH候选满足第三条件、且目标PDCCH候选的第一时刻与第二PDCCH候选的第一时刻间的时间偏移量小于或等于第二门限值，则PDCCH重复传输装置可以从第一传输单元的起始传输时刻起的预设切换预留时间(即下述实施例中的第二时长)之后，执行BWP切换过程。
本申请实施例中，在X个PDCCH候选满足第三条件、且目标PDCCH候选的第一时刻与第二PDCCH候选的第一时刻间的时间偏移量大于第二门限值的情况下，由于可能会出现X个PDCCH候选中，时域资源上的第一个PDCCH候选上未盲检测出PDCCH的情况，因此，PDCCH重复传输装置可以从该第二PDCCH候选所在的第一传输单元的起始传输时刻起的第一时长之后，即预设切换预留时间和预设时长之和的时长之后，才执行BWP切换过程。
可选地，在本申请的再一种可能的实现方式中，上述步骤103a具体可以通过下述的步骤103a4实现。
步骤103a4、PDCCH重复传输装置根据BWP切换指示信令和目标PDCCH候选的时域资源，在X个PDCCH候选满足第四条件的情况下，从第二传输单元的起始传输时刻起的第二时长之后，或，从第一传输单元的起始传输时刻起的第一时长之后，执行BWP切换过程。
可选地，本申请实施例中，上述第四条件为：X个PDCCH候选在不同传输单元中传输。
可选地，本申请实施例中，上述第二传输单元为：目标PDCCH候选所在的传输单元。
可选地，本申请实施例中，上述第二时长为：预设切换预留时间。
可以理解，在X个PDCCH候选在不同传输单元中传输(即当网络侧设备配置了时隙内重复inter-slot repetition传输)，PDCCH重复传输装置可以从第二传输单元的起始传输时刻起的预设切换预留时间之后，执行BWP切换过程。
本申请实施例中，在X个PDCCH候选满足第四条件的情况下，由于可能会出现X个PDCCH候选中，时域资源上的第一个PDCCH候选上未盲检测出PDCCH的情况，因此，PDCCH重复传输装置可以从第二传输单元的起始传输时刻起的第二时长之后，即预设切换预留时间之后，才执行BWP切换过程，或者，PDCCH重复传输装置可以从第一传输单元的起始传输时刻起的第一时长之后，即预设切换预留时间和预设时长之和的时长之后，才执行BWP切换过程。
如此可知，由于PDCCH重复传输装置可以根据BWP切换指示信令和一个PDCCH候选的时域资源，执行BWP切换过程，即PDCCH重复传输装置可以确定从一个PDCCH候选所在的传输单元的起始传输时刻起的预留时间之后，执行BWP切换过程，因此，可以提升PDCCH重复传输装置执行BWP切换过程的可靠性。
下面将举例说明PDCCH重复传输装置是如何根据目标PDCCH候选的时域资源，向网络侧设备发送确定信息的。
在相关技术中，在PDCCH重复传输装置成功检测或未检测到PDCCH候选的情况下，PDCCH重复传输装置可以向网络侧设备发送ACK/NACK信息，以使得网络侧设备可以根据该ACK/NACK信息执行相关操作。然而，在网络侧设备为PDCCH重复传输装置配置PDCCH重复传输的情况下，PDCCH重复传输装置如何向网络侧设备发送ACK/NACK，相关技术中并没有规定。
然而，在本申请实施例中，在网络侧设备为PDCCH重复传输装置配置PDCCH重复传输的情况下，PDCCH重复传输装置可以根据第一信令和一个PDCCH候选的时域资源，向网络侧设备发送确定信息，以解决上述相关技术中存在的问题。
可选地，本申请实施例中，在上述步骤103之前，本申请实施例提供的PDCCH重复传输还可以包括下述的步骤401，并且上述步骤103具体可以通过下述的步骤103b实现。
步骤401、PDCCH重复传输装置获取第一信令。
需要说明的是，针对PDCCH重复传输装置获取第一信令的说明，可以参考上述实施例中PDCCH重复传输装置获取BWP 切换指示信令的具体描述，本申请实施例在此不再赘述。
本申请实施例中，上述第一信令包括以下任一项：辅小区休眠指示信令、半持续PDSCH调度释放指示信令。
步骤103b、PDCCH重复传输装置根据第一信令和目标PDCCH候选的时域资源，向网络侧设备发送确定信息。
本申请实施例中，上述目标PDCCH候选为：X个PDCCH候选中，时域资源上的最后一个PDCCH候选。
可选地，本申请实施例中，上述步骤103b具体可以通过下述的步骤103b1实现。
步骤103b1、PDCCH重复传输装置根据第一信令和目标PDCCH候选的时域资源，从目标PDCCH候选在时域资源上的结束符号起的Q个符号之后，向网络侧设备发送确定信息。
本申请实施例中，Q为正整数。
本申请实施例中，上述目标PDCCH候选为：X个PDCCH候选中，时域资源上的最后一个PDCCH候选。
可以理解，Q个符号在时域资源上的第一个符号的起始位置，是从目标PDCCH候选在时域资源上的最后一个符号结束后开始计算的。
举例说明，如图5所示，X个PDCCH候选包括：PDCCH候选1和PDCCH候选2，该PDCCH候选2为：PDCCH候选1和PDCCH候选2中，时域资源上的最后一个PDCCH候选。PDCCH重复传输装置可以根据第一信令和PDCCH候选2的时域资源，从该PDCCH候选2在时域资源上的结束符号(例如符号10)起的Q个符号之后，向网络侧设备发送确定信息。
进一步可选地，本申请实施例中，上述确定信息具体可以为：ACK/NACK信息。其中，ACK/NACK信息用于指示：PDCCH重复传输装置是否成功检测到PDCCH候选。
如此可知，由于PDCCH重复传输装置可以根据第一信令和一个PDCCH候选的时域资源，向网络侧设备发送确定信息，即PDCCH重复传输装置可以确定从一个PDCCH候选在时域资源上的一个符号起的至少一个符号之后，向网络侧设备发送确定信息，因此，可以提升PDCCH重复传输装置发送确定信息的可靠性。
下面将举例说明PDCCH重复传输装置是如何根据目标PDCCH候选的时域资源，确定PDSCH的调度图案的。
可选地，本申请实施例中，在上述步骤103之前，本申请实施例提供的PDCCH重复传输还可以包括下述的步骤501，并且上述步骤103具体可以通过下述的步骤103c实现。
步骤501、PDCCH重复传输装置获取PDSCH调度信令。
需要说明的是，针对PDCCH重复传输装置获取PDSCH调度信令的说明，可以参考上述实施例中PDCCH重复传输装置获取BWP切换指示信令的具体描述，本申请实施例在此不再赘述。
步骤103c、PDCCH重复传输装置根据PDSCH调度信令和目标PDCCH候选的时域资源，确定PDSCH的调度图案。

X个PDCCH候选中，关联的搜索空间的索引值最大的PDCCH候选，或关联的搜索空间的索引值最小的PDCCH候选；
X个PDCCH候选中，关联的控制资源集的索引值最大的PDCCH候选，或关联的控制资源集的索引值最小的PDCCH候选。
可以理解，PDCCH重复传输装置可以从X个PDCCH候选中，定义一个参考PDCCH候选(即目标PDCCH候选)，并根据PDSCH调度信令和该参考PDCCH候选的时域资源，确定PDSCH的调度图案。
可选地，本申请实施例中，在PDSCH采用第一映射方式的情况下，目标PDCCH候选在时域资源上的符号，位于同一传输单元的前R个符号，R为正整数。
进一步可选地，本申请实施例中，上述第一映射方式具体可以为：类型(type)A的映射方式。
进一步可选地，本申请实施例中，R的数值具体可以为：3。
可选地，本申请实施例中，在PDSCH采用第二映射方式的情况下，目标PDCCH候选在时域资源上的起始符号，不晚于PDSCH在时域资源上的起始符号。
进一步可选地，本申请实施例中，上述第二映射方式具体可以为：类型(type)B。
可选地，本申请实施例中，在目标PDCCH候选为X个PDCCH候选中、时域资源上的最后一个PDCCH候选的情况下，PDSCH的调度图案是基于第一参数值确定的。
可选地，本申请实施例中，具体用于表征以下任一项：
在PDSCH在时域资源上的起始符号，相对于目标PDCCH候选在时域资源上的起始符号的位置提前T个符号或延迟T个符号，T为正整数；
PDSCH的调度起始符号，相对于目标符号的位置；
其中，目标符号，与X个PDCCH候选中的任一个PDCCH候选中，时域资源上的第一个符号或最后一个符号间隔为目标数值；
目标数值由以下任一项确定：预设的数值、网络侧设备基于PDCCH重复传输装置上报的能力确定的数值。
进一步可选地，本申请实施例中，上述第一参数值具体可以为：SLIV(startSymbolAndLength)值。
可以理解，DCI中携带一个TDRA(Time domain resource assignment)表，指示PDSCH相对于PDCCH的调度图案(包括时隙offset，PDSCH起始符号位置，PDSCH的符号长度)。其中TDRA是通过N个比特(bit)表示。
不同的bit表示的图案是通过高层信令配置下来的。
以下将以两个示例进行举例说明：
示例1：网络侧设备通过高层信令配置一个参数，用1bit表示，用于区分SLIV中携带的起始符号信息是表征PDSCH相对PDCCH提前或者延迟T个符号。
例如bit＝0，则表示延迟；bit＝1表示提前。
本申请实施例中，bit可以等于1，即PDSCH可以相对PDCCH提前。
举例说明，如图6所示，PDSCH起始符号相对于第二个PDCCH的起始符号提前5个符号。
示例2：PDCCH重复传输装置上报一个能力，用于指示PDSCH调度起始符号距离任一个PDCCH候选中的第一个PDCCH候选或者第二个候选的起始符号的最大间隔。
举例说明，如图7所示，PDSCH起始符号相对于目标符号延迟1个符号。其中，目标符号和第二个PDCCH候选的起始符号间隔目标数值gap＝5个符号。其中该gap值可以预定义或者参考终端上报能力。
需要说明的是，本申请实施例提供的PDCCH重复传输方法，执行主体可以为PDCCH重复传输方法装置，或者，该PDCCH重复传输方法装置中的用于执行PDCCH重复传输方法方法的控制模块。本申请实施例中以PDCCH重复传输方法装置执行PDCCH重复传输方法为例，说明本申请实施例的。
需要说明的是，网络侧设备实施例是与终端侧实施例对应的，终端侧实施例的所有实现方式均适用于网络侧实施例，并能达到相同的技术效果，故不再赘述。
