下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的信道监听方法进行详细地说明。
如图2所示，本申请实施例提供了一种信道监听方法，应用于终端，该方法包括：
步骤201：在至少两个物理下行控制信道PDCCH监听机会中监听PDCCH；
其中，每个所述PDCCH监听机会对应所述PDCCH的部分控制信道单元CCE。也就是说明，每个所述PDCCH监听机会传输所述PDCCH的部分CCE。
这里，每个PDCCH监听机会对应PDCCH的部分CCE，所述至少两个PDCCH监听机会对应的CCE组合形成完整的PDCCH，或者，每个所述PDCCH监听机会对应的所述CCE的数量小于该PDCCH的聚合等级对应的CCE数量。
上述PDCCH的聚合等级为网络设备配置的，优选的，上述PDCCH的聚合等级大于或者等于预设阈值，例如，该预设阈值为16。
例如，上述PDCCH的聚合等级为L，即该PDCCH包括L个CCE，则多个PDCCH监听机会中的每个监听机会传输L个CCE中的部分CCE。如图3所示，L个CCE分布于2个监听机会中，每个监听机会对应L/2个CCE。即通过两个监听机会中的CCE传输该PDCCH的所有信息。而现有技术中，如图4所示，则是将L个CCE在一个PDCCH监听机会中进行传输。即一个PDCCH监听机会中的L个CCE传输了该PDCCH的所有信息。因此，本申请实施例通过每个PDCCH监听机会对应所述PDCCH的部分CCE，使得终端可以基于多个PDCCH监听机会实现PDCCH的联合检测。可选的，所述至少两个PDCCH监听机会属于相同的控制资源集CORESET或属于不同的控制资源集；
或者，至少两个所述PDCCH监听机会属于相同的搜索空间集(Search Space Set，SS Set)或属于不同的搜索空间集。
在两个所述PDCCH监听机会属于不同的控制资源集的情况下，两个所述PDCCH监听机会的以下至少一项参数相同：
资源单元组REG束的大小(REG bundle size)；
交织大小(Interleave size)；
预编码颗粒度；
控制资源集总的CCE个数；
控制资源集的资源块数；
控制资源集的符号数。
本申请实施例的信道监听方法，在至少两个物理下行控制信道PDCCH监听机会中监听PDCCH，每个所述PDCCH监听机会对应所述PDCCH的部分控制信道单元CCE，从而使得终端可以基于多个PDCCH监听机会实现PDCCH的联合检测，提升了PDCCH的传输性能。
可选的，每个所述PDCCH监听机会中对应所述CCE所承载信息的资源的索引相同。
也就是说，在每个PDCCH监听机会的相同位置分布有所述CCE。
可选的，每个所述PDCCH监听机会中对应所述CCE的资源的索引是根据所述PDCCH监听机会的编号确定的。
例如，第j个PDCCH监听机会传输的CCE所承载信息的起始位置的偏移值与j相关。
进一步可选的，所述PDCCH监听机会的编号根据以下至少一项确定：
时间顺序；
频率顺序；
服务小区索引；
控制资源集索引；
搜索空间集合索引。
例如，多个PDCCH监听机会在不同的时间，按时间从前到后的顺序，进行PDCCH的编号；或者多个PDCCH监听机会在不同的服务小区，根据服务小区索引从小到大或者从大到小的顺序进行排序；或者多个相同时间的不同频率，则根据频率从低到高或者从高到低的顺序进行编号；或者多个PDCCH监听机会在不同的CORESET中，则根据CORESET索引从大到小或者从小到大的顺序进行编号。
可选的，所述在至少两个物理下行控制信道PDCCH监听机会中进行PDCCH的监听之前，所述方法还包括：
确定每个所述PDCCH监听机会对应的所述CCE的数量。
本申请实施例中，每个所述PCCH监听机会对应的CCE的数量可以相等，也可以不等。
在每个所述PDCCH监听机会对应的所述CCE的数量相同时，所述确定 每个所述PDCCH监听机会对应的所述CCE的数量，包括：
根据所述PDCCH的聚合等级以及所述PDCCH监听机会的数目，确定每个所述PDCCH监听机会对应的所述CCE的数量。
例如，传输的PDCCH的聚合等级为L，在N个PDCCH监听机会中进行监听，则每个PDCCH监听机会对应的CCE的数量为L/N。
在每个所述PDCCH监听机会对应的所述CCE的数量不等时，所述每个所述PDCCH监听机会对应的所述CCE的数量，包括：
根据网络设置的指示或根据预设CCE数，确定每个所述PDCCH监听机会对应的所述CCE的数量。即每个PDCCH监听机会对应的CCE的数量为预设的或者为网络设备指示的。
在本申请的一个实施例中，假设一个PDCCH的聚合等级为L，即需要L个CCE进行PDCCH传输，网络设备可以配置这L个CCE分布于多个PDCCH MO中(也即L个CCE在多个PDCCH MO中进行传输)。例如，L个CCE分布于2个PDCCH MO中，每个PDCCH MO中传输L/2个CCE。上述多个PDCCH MO可以由网络指示，多个MO可以属于相同的CORESET或者不同的CORESET，属于相同或者不同的search space set。UE在网络指示的多个PDCCH MO中进行PDCCH监听。
在不同的PDCCH MO中传输PDCCH的多个CCE部分，且每个PDCCH MO中对应CCE的资源的索引相同，或，每个PDCCH MO中对应CCE的起始位置与PDCCH MO有确定的映射位置关系。一种确定的映射位置关系为：CCE编号和PDCCH MO的编号相关。例如，

Figure PCTCN2021104237-appb-000008
中的最大值。
f(mo_idx)＝mo_idx*N，其中，N为正整数，mo_idx表示监测机会MO的索引。
通过上述公式，UE可以确定不同监听机会中PDCCH的部分CCE传输的资源，则可以将不同监听机会中的CCE一起进行联合PDCCH检测。避免了UE需要将多个不同的PDCCH监听机会进行两两组合联合检测的多次尝试。
可选的，不同的所述PDCCH监听机会对应的传输配置指示TCI状态相同或者不同。
所述至少两个PDCCH监听机会对应的TCI状态为网络设备配置的一个或多个TCI状态；
或者，所述至少两个PDCCH监听机会对应的TCI状态为媒体接入层控制单元MAC-CE激活的一个或者多个TCI状态。
本申请实施例中，对于多个PDCCH MO的PDCCH监听，UE可以使用不同的TCI状态(state)在不同的PDCCH MO中进行监听。如果多个PDCCH MO属于同一个CORESET，网络可以使用RRC信令或者MAC-CE指示多个TCI state，UE根据PDCCH MO的顺序和TCI state的编号，循环顺序的在多个PDCCH MO上使用对应的TCI state进行PDCCH的监听。
例如，网络配置了在2个PDCCH MO上进行PDCCH监听，每个PDCCH MO传输聚合等级为L的PDCCH的L/2个CCE，且网络通过RRC或者MAC-CE指示了2个TCI state，索引为n1，n2，则UE在两个PDCCH MO上分别使用TCI state n1和n2进行监听。
或者，网络配置了在4个PDCCH MO上进行PDCCH监听，每个PDCCH MO传输聚合等级为L的PDCCH的L/4个CCE，且网络通过RRC或者MAC-CE指示了2个TCI state，索引为n1，n2，则UE在4个PDCCH MO上分别使用TCI state n1，n2，n1，n2进行监听。
可选的，所述在至少两个物理下行控制信道PDCCH监听机会中监听PDCCH，包括：
在网络设备配置的预设时间段内的PDCCH监听对应的盲检能力大于终端在当前服务小区上的PDCCH盲检能力的情况下，在每个所述PDCCH监听机会中优先监听第一PDCCH或优先监听第二PDCCH；
其中，所述盲检能力包括预设时间段内的盲检次数和所述预设时间段内不重叠的CCE的个数，所述第一PDCCH为配置了N个监听资源联合检测的PDCCH，所述第二PDCCH为除所述第一PDCCH之外的PDCCH，N为大于1的正整数。
其中，所述第一PDCCH的优先级根据N确定，例如，N越大，优先级越高，或者，N越小，优先级越高。也就是说，在存在多个第一PDCCH的情况下，根据N的大小，来确定多个第一PDCCH的检测优先级。
在本申请的具体实施例中，UE在每个服务小区(serving cell)上的PDCCH盲检能力包含最大的盲检次数及最大的不重叠的CCE个数。然而，网络可能实际配置的PDCCH检测在一个时间段(1个或者多个slot或者符号)内，导致盲检次数或者不重叠的CCE个数大于UE的盲检能力。这样UE需要放弃USS的索引值较高的SS set中的PDCCH监听。
在引入了在多个PDCCH MO中进行PDCCH检测，且每个PDCCH MO只传输PDCCH的部分CCE的情况下，可以对上述PDCCH的放弃监听的规则进行进一步优化。
例如，在每个PDCCH MO中，UE优先检测配置了N>1个PDCCH MO联合检测的部分PDCCH。这样可以保证UE PDCCH检测的性能。如果N的数值越大，则优先级越高，反之优先级越低。一般这种方案在每个PDCCH MO传输的PDCCH的部分CCE不能正确译码的情况下更适用。
或者，UE优先检测除了配置了N个PDCCH MO联合检测的PDCCH之 外的其它PDCCH。例如，当该PDCCH MO为N个PDCCH MO中除了第一个PDCCH MO之外的MO时，可以降低这种部分传输的PDCCH监听的优先级。即认为已经进行过部分CCE检测的PDCCH的优先级降低。这种方案要求第一个PDCCH MO传输的部分CCE的PDCCH是可以被正确译码的PDCCH。如果需要在同一个PDCCH MO监听多个N值不同的PDCCH，N值越小，则优先级越高。
上述优先级越高，说明在确定对应的搜索空间集合中的PDCCH是否检测/放弃的过程中，优先进行检测或不优先放弃检测的PDCCH。
可选的，本申请实施例的信道监听方法，还包括：
根据所述至少两个PDCCH监听机会中最后一个PDCCH监听机会所在的时间单元，确定PDCCH指示的终端行为；
所述终端行为包括以下至少一项：
根据PDCCH指示的时域资源分配TDRA，确定物理上行共享信道PUSCH发送的时间资源或者PDSCH接收的时间资源；
根据PDCCH指示，确定传输混合自动重传请求确认HARQ-ACK反馈的物理上行控制信道PUCCH的时间资源；
带宽部分BWP切换时间；
BWP切换时延；
启动或者重启非连续接收静止定时器；
最小Minimum K0的生效时间，K0为传输PDSCH调度信息的PDCCH和被调度的PDSCH之间的时隙偏移；
最小Minimum K2的生效时间，K2为传输PUSCH调度信息的PDCCH和被调度的PUSCH之间的时隙偏移；
搜索空间集合切换的生效时间；
指示非周期信道状态信息CSI上报的信道状态信息参考信号CSI-RS所在的时隙资源。
本申请实施例中，在网络配置了在多个MO上进行PDCCH传输，其中每个MO只传输PDCCH的部分CCE的情况下，PDCCH指示的UE行为根据该多个MO中的最后一个MO作为参考时间确定。
如果PDCCH用于调度PDSCH接收或者PUSCH传输，对应接收或者发送的时间以最后一个PDCCH MO的时间资源为参考时间，根据PDCCH指示的调度信息确定PDSCH或者PUSCH的接收或发送的符号。
类似的，如果PDCCH触发非周期CSI上报，对应的CSI-RS资源根据多个PDCCH MO中的最后一个PDCCH MO确定，通常在最后一个PDCCH MO所在的时隙，或者根据网络配置的时间偏移确定的时隙。
对于一些非调度的PDCCH，例如，指示半静态调度PDSCH释放的PDCCH，UE根据PDCCH的结束符号及PDCCH中的HARQ-ACK时间资源的指示，确定HARQ-ACK反馈的PUCCH资源，当网络配置在多个PDCCH MO中传输PDCCH，每个PDCCH MO中监听PDCCH的部分CCE的情况下，UE根据最后一个PDCCH MO，确定HARQ-ACK反馈的时间资源。
对于PDCCH中包含带宽部分指示符字段(bandwidth part indicator field)，如果指示一个与当前的激活BWP不同的BWP，则UE转换到新的BWP上。如果网络配置了UE在多个PDCCH MO上监听PDCCH，每个PDCCH MO中监听该PDCCH的部分CCE。则UE在N个PDCCH MO中检测到任意一个PDCCH之后，都在参考PDCCH MO进行BWP切换，即从参考PDCCH MO所在的子帧或时隙启动或者重启带宽部分静止定时器(Bwp InactivityTimer)。
UE开始执行BWP切换的时间点，或者开启或者重启bwpInactivityTimer的时间点，可以用上述PDCCH MO的参考PDCCH MO作为参考时间点，可以为参考PDCCH MO的以下信息：
开始符号，结束，结束的下一个符号；
所在的时隙，子帧，或者下一个时隙或者下一个子帧。
所述参考PDCCH MO可以为：
N个PDCCH MO中的最后一个MO；
N个PDCCH MO中的最后一个有效的MO；
在上述参考时间点T1之后，UE完成BWP切换，T1的时间长短取决于UE能力。
同理，对于指示如下功能的PDCCH：
启动或者重启非连续接收静止定时器(drx InactivityTimer)，生效时间为 T2；
Minimum K0，k2的生效时间为T3；
搜索空间集合切换的生效时间为T4；
如果PDCCH在多个PDCCH MO中监听，且每个PDCCH MO中只监听该PDCCH的部分CCE。则上述生效时间的参考时间为多个PDCCH MO中的最后一个MO。
