背景技术
处于空闲(idle)态的用户设备(user equipment，UE)可以接收寻呼(paging)物理下行控制信道(physical downlink control channel，PDCCH)。其中，paging PDCCH可以用于寻呼UE、传输商业移动警报服务(Commercial Mobile Alert Service，CMAS)、传输地震和海啸预警系统(Earthquake and Tsunami Warning System，ETWS)，等等。
然而，由于在一个寻呼时机(paging occasion，PO)中UE被寻呼的概率比较低，因此如果UE周期性地检测(也可以称为监听)paging PDCCH，那么UE将大概率地检测不到该paging PDCCH，如此使得UE的paging PDCCH检测为不必要的paging PDCCH检测，从而造成UE的功耗浪费。
发明内容

需要说明的是，本申请实施例中的示例均是以下行控制信道为PDCCH为例进行示例性说明的，实际实现时，下行控制信道还可以为其他任意可能的信道。
可选地，本申请实施例中，本申请实施例提供的信道检测方法还可以包括下述的步骤202。上述步骤201具体可以通过下述的步骤201a实现。
步骤202、UE根据第一信息，确定寻呼指示信号的第一传输资源。
步骤201a、UE在第一传输资源上，接收网络设备发送的寻呼指示信号。
其中，上述第一信息可以包括以下至少一项：
与寻呼指示信号关联的同步信号块(synchronization signal and physical broadcast channel block，SSB)的索引；
PO中的寻呼下行控制信道监听时机(monitoring occasion，MO)；

本申请实施例中，在UE接收上述寻呼指示信号之前，UE可以先根据上述第一信息，确定网络设备发送寻呼指示信号的传输资源(即上述第一传输资源)，然后UE可以直接在该第一传输资源上，接收寻呼指示信号。
需要说明的是，本申请实施例中，由于一个PO中的寻呼下行控制信道监听时机与网络设备发送的SSB关联，例如该PO中的N个paging PDCCH监听时机与网络设备发送的N个SSB按时间顺序一一对应，因此在UE确定PO中的寻呼下行控制信道监听时机的情况下，UE可以根据该PO中的寻呼下行控制信道监听时机，确定关联的SSB。
其中，上述N个SSB可以为网络设备通过高层信令配置的N个SSB。
示例性的，假设网络设备配置N个SSB的发送，则每个PO中包括N个paging PDCCH MO，该N个paging PDCCH MO和该N个SSB按SSB的索引从小到大，按时间顺序相关联；那么PO中的第1个paging PDCCH MO对应于网络设备发送的索引最低的SSB(即按照从小到大的顺序排第一的SSB)，PO中的最后l个paging PDCCH MO对应于网络设备发送的索引最大的SSB。
可选地，本申请实施例中，对于上述N个SSB和与每个SSB对应的PO中的下行控制信道监听时机，第n(1≤n≤N)个SSB和与该第n个SSB对应的第n个下行控制信道监听时机满足第三准共址(quasi co-located，QCL)关系。
其中，上述第三QCL的QCL类型可以包括以下至少一项：
-QCL-类型A(type A)：{多普勒频移(Doppler shift)，多普勒扩散(Doppler spread)，平均延迟(average delay)，延迟扩散(delay spread)}；

-QCL-type C：{average delay，Doppler shift}；
-QCL-type D：{空间接收参数(Spatial Rx parameter)}。
本申请实施例中，上述第一信息不同，UE确定上述第一传输资源的方式可以不同。第一信息可以包括三种可能的情况，分别为下述的情况一、情况二和情况三。
情况一：第一信息包括与寻呼指示信号关联的SSB的索引。
情况二：第一信息包括PO中的寻呼下行控制信道监听时机。
情况三：第一信息包括与寻呼指示信号关联的SSB的索引和UE所在的UE分组。
需要说明的是，实际实现时，第一信息还可以包括其他任意可能的情况，具体可以根据实际使用需求确定，本申请实施例不作限定。
下面分别对基于上述情况一、情况二和情况三，UE确定第一传输资源的方式进行示例性的说明。
可选地，基于上述情况一(第一信息包括与寻呼指示信号关联的SSB的索引)，上述步骤202具体可以通过下述的步骤202a实现。
步骤202a、UE根据SSB索引次序，在第二传输资源上，按照关联顺序确定寻呼指示信号的第一传输资源。
其中，上述第二传输资源可以包括至少一个寻呼指示信号的传输资源；上述SSB索引次序可以为与寻呼指示信号关联的SSB的索引的次序；上述关联顺序可以为与寻呼指示信号关联的SSB和第二传输资源的关联顺序，也可以称为第一关联顺序。
需要说明的是，除特殊说明外，本申请实施例中涉及的关联顺序均是指与寻呼指示信号关联的SSB和第二传输资源的关联顺序，即上述第一关联顺序。
本申请实施例中，网络设备可以在时域资源和/或频域资源上配置一个或多个寻呼指示信号的传输资源。该一个或多个寻呼指示信号的传输资源可以为第二传输资源中的传输资源，即第二传输资源可以包括该一个或多个寻呼指示信号的传输资源。
可选地，本申请实施例中，上述第二传输资源可以包括以下至少一项：
包括SSB的全部或部分传输符号的传输资源；
SSB的传输资源在时域上偏移预设时间间隔的传输资源；
与SSB的传输资源按照关联顺序关联的传输资源。
需要说明的是，本申请实施例中，上述SSB可以为与寻呼指示信号关联的SSB。
可选地，本申请实施例中，在上述第二传输资源包括SSB的传输资源在时域上偏移预设时间间隔的传输资源的情况下，如果第二传输资源包括多个寻呼指示信号的传输资源，那么与该多个寻呼指示信号关联的SSB的时间偏移值(即预设时间间隔)可以相同，也可以不同。具体可以根据实际使用需求确定，本申请实施例不作限定。
其中，上述第二传输资源可以包括在SSB的传输资源上向前偏移的传输资源和在SSB的传输资源上向后偏移的传输资源中的至少一项。
可选地，本申请实施例中，上述关联顺序可以包括以下至少一项：时间顺序、频率顺序、先时间后频率的顺序、先频率后时间的顺序。
可以理解，上述与SSB的传输资源按照关联顺序关联的传输资源可以包括以下至少一项：与SSB的传输资源按照时间顺序关联的传输资源、与SSB的传输资源按照频率顺序关联的传输资源、与SSB的传输资源按照先时间后频率的顺序关联的传输资源、与SSB的传输资源按照先频率后时间的顺序关联的传输资源。
本申请实施例中，网络设备可以在第二传输资源上，根据与寻呼指示信号关联的SSB的索引次序(即上述SSB索引次序)，按照与寻呼指示信号关联的SSB和第二传输资源的关联顺序(即第一关联顺序)，映射寻呼指示信号。如此，UE可以根据网络设备在第二传输资源上映射寻呼指示信号的方式，确定上述网络设备发送寻呼指示信号的第一传输资源。
下面通过下述的示例1-示例5，对网络设备映射寻呼指示信号的方式进行示例性的说明。
示例1：上述第二传输资源包括SSB的传输资源按照关联顺序关联的传输资源，关联顺序包括时间顺序，那么，如图3所示，寻呼指示信号的第1个传输机会，对应于网络设备发送的索引值最小(最低)的SSB的传输机会对应的传输机会，即寻呼指示信号的第l个传输机会对应于网络设备发送的索引值从小到大排第l的SSB的传输机会对应的传输机会。
示例2：上述第二传输资源包括SSB的传输资源在时域上偏移预设时间间隔的传输资源，且该预设时间间隔为X个符号，上述关联顺序为时间顺序，那么如图4所示，寻呼指示信号的第1个传输机会，对应于网络设备发送的索引值最小(最低)的SSB的传输机会向后偏移X个符号的传输机会。
示例3：如图5所示，上述第二传输资源包括“包括SSB的部分传输符号的传输资源”，上述关联顺序为时间顺序，那么UE可以在接收SSB时，完成寻呼指示信号的接收。
示例4：在上述第二传输机会中包括网络设备在多个频率位置和时间位置配置多个寻呼 指示信号的传输资源的情况下，该关联顺序可以为先频率后时间的顺序，即网络设备在第二传输资源中，根据先频率后时间的顺序映射方式映射寻呼指示信号。如图6所示，在一个时间段内，不同的SSB关联的寻呼指示信号发送的时间或者频率位置不同，在频率上支持2个寻呼指示信号以频分复用(frequency division multiplexing，FDM)的方式传输。SSB的索引按从小到大的顺序排序后，第一个SSB关联的寻呼指示信号在第一个时刻的第一频率位置传输，第2个SSB在第一个时刻的第二频率位置传输，第3个SSB在第二个时刻的第一频率位置传输，第4个SSB在第二个时刻的第二频率位置传输。
可选地，在上述示例4中，在不同频率位置传输的寻呼指示信号对应的频率偏移值可以不同。
另外，示例4中的寻呼指示信号可以为序列形式的寻呼指示信号，即寻呼指示信号为信号序列。
示例5：在寻呼指示信号为离散的信号序列，即寻呼指示信号在频率或者时间上的映射不连续，不同频率位置对应的频率偏移不同，或不同时间位置对应的时间偏移不同。那么如图7所示，对于一个slot内的一个寻呼指示信号的信号序列的映射方式，在每个符号上映射X＝4个SSB关联的寻呼指示信号的信号序列，该信号序列(也可以称为序列)映射在至少一个符号上，在每个符号上的频率间隔Y＝4，在每个资源块(resource block，RB)上的起始资源单元(resource element，RE)不同，即RE偏移值不同，频率偏移值(预定义的值或网络设备配置的值)不同。网络设备可以按照先频率后时间的顺序进行映射，前P＝4个SSB关联的寻呼指示信号在符号k0∈{2,9}上传输，后Q＝P-4＝4个SSB关联的寻呼指示信号在符号k1∈{3,10}上传输，即k1＝k0+Δk，Δk为符号的时间偏移。如此，UE可以按照先频率后时间的顺序，从这些符号中确定寻呼指示信号的传输资源。
需要说明的是，本申请实施例中，对于示例5中的X，Y，Q，P，k0，k1，kl的数值大小不受限于示例5中示出的数值，也可以为其他任意可能的数值，这些取值可以为预定义或者网络配置。
另外，上述图7中仅示意了寻呼指示信号在一个RB，一个时隙(slot)中的映射方式，实际可以不受此限制。实际实现时，寻呼指示信号可以在多个RB上或者多个slot上传输。其中，该多个RB或者多个slot可以是连续的，也可以是不连续的。
可选地，本申请实施例中，上述步骤202a具体可以通过下述的步骤202a1实现。
步骤202a1、UE根据SSB索引次序，在第二传输资源中的预设时域资源上，按照关联顺序确定第一传输资源。
其中，上述预设时域资源可以包括以下至少一项：下行时隙、特殊时隙、下行符号、灵活符号。
本申请实施例中，上述特殊时隙可以为包括下行符号，上行符号，灵活符号中的至少2种符号的时隙。
可选地，本申请实施例中，寻呼指示信号(例如寻呼指示信号的信号序列)可以在多个符号上传输，从而UE可以根据该多个符号进行频偏估计和补偿。
可选地，寻呼指示信号可以在多个符号上进行重复传输。
示例性的，假设网络设备仅在下行符号上传输寻呼指示信号，例如寻呼指示信号配置在多个slot上重复传输，那么在UE确定如图8中的(a)所示的多个slot之后，UE可以在 该多个slot上重复接收寻呼指示信号。如果第二传输资源中存在非下行符号或非下行时隙，那么UE不在这些非下行符号或非下行时隙上接收寻呼指示信号，即如图8中的(b)所示，UE不进行剩余的寻呼指示信号的接收；或者，如图8中的(c)所示，UE推迟接收剩余的寻呼指示信号。
可选地，基于上述情况二(第一信息包括PO中的寻呼下行控制信道监听时机)，UE可以根据PO中的寻呼下行控制信道监听时机，确定与寻呼指示信号关联的SSB，然后再根据与寻呼指示信号关联的SSB的索引，确定上述第一传输资源。
需要说明的是，对于根据与寻呼指示信号关联的SSB的索引，确定第一传输资源的方式具体可以参见上述实施例中的详细描述，为避免重复，此处不再赘述。
可选地，基于上述情况三(第一信息包括与寻呼指示信号关联的SSB的索引和UE所在的UE分组)，网络设备可以根据与寻呼指示信号关联的SSB的索引的次序(即上述SSB索引顺序)，按照与寻呼指示信号关联的SSB和上述第二传输资源的关联顺序(即上述第一关联顺序)和寻呼指示信号与UE所在的UE分组的第二关联顺序，在上述第二传输资源上映射寻呼指示信号，从而UE可以根据SSB索引顺序，按照第一关联顺序和第二关联顺序，确定上述第一传输资源。
可选地，本申请实施例中，网络设备可以先按照第一关联顺序在第二传输资源上映射寻呼指示信号，然后再按照第二关联顺序在第二传输资源上映射寻呼指示信号；或者网络设备可以先按照第二关联顺序在第二传输资源上述映射寻呼指示信号，然后再按照第一关联顺序在第二传输资源上映射寻呼指示信号。具体可以根据实际使用需求确定，本申请实施例不作限定。
示例性的，如图9所示，UE根据UE编号(UE-ID)分成了G＝2个UE组(group)，在网络设备配置了Z＝8个传输资源，则每个SSB关联的寻呼指示信号的资源数为G＝2个，UE可以先确定一个SSB关联的所有UE group的寻呼指示信号的传输资源，再顺序确定剩余的SSB关联的所有UE group的寻呼指示信号的传输资源；或者，UE也可以先确定一个UE group关联的所有SSB的寻呼指示信号的传输资源，再顺序确定剩余的UE group关联的所有SSB的寻呼指示信号的传输资源，从而确定上述第一传输资源。
本申请实施例中，由于寻呼指示信号与SSB关联，寻呼下行控制信道也与SSB关联，因此寻呼指示信号和寻呼下行控制信道也关联，如此在寻呼指示信号的第一传输资源确定之后，UE可以根据寻呼指示信号的第一传输资源，确定寻呼下行控制信道的第四传输资源。
本申请实施例中，如图3-图6、或图8所示，上述第四传输资源在时间上可以位于上述第一传输资源之后。
可选地，本申请实施例中，在UE确定上述第一传输资源之后，UE可以根据寻呼指示信号和与寻呼指示信号关联的SSB之间满足QCL关系(例如本申请实施例中的第一QCL关系)，在第一传输资源上接收网络设备发送的寻呼指示信号。
可选地，本申请实施例中，基于上述步骤202或步骤202a，上述步骤201a具体可以通过下述的步骤201a1实现。
步骤201a1、UE按照第一QCL关系，在第一传输资源上，接收网络设备发送的寻呼指示信号。
其中，上述第一QCL关系可以为寻呼指示信号和与寻呼指示信号关联的SSB之间的 QCL关系。也就是说，寻呼指示信号和与寻呼指示信号关联的SSB之间满足第一QCL关系。
可选地，本申请实施例中，上述第一QCL关系可以包括以下至少一项：

可选地，本申请实施例中，在上述寻呼指示信号为信号序列的情况下，该信号序列可以占用一个或多个正交频分复用(orthogonal frequency division multiplex，OFDM)符号。
本申请实施例中，若寻呼指示信号(即上述信号序列)占用多个符号，则在该多个符号上关联相同SSB的寻呼指示信号也满足上述第一QCL关系。
可选地，本申请实施例中，上述多个符号可以为相邻或者不相邻的符号。其中，当该多个符号为不相邻的符号时，该多个符号之间的时间间隔可以由网络设备配置。
可选地，本申请实施例中，在寻呼指示信号的信号序列占用多个OFDM符号的情况下，上述步骤201a具体可以通过下述的步骤201a2实现。
步骤201a2、UE根据第二信息，在第一传输资源上，接收寻呼指示信号的信号序列。
其中，上述第二信息可以包括以下至少一项：寻呼指示信号的信号序列的生成方式、第二QCL关系。该信号序列的生成方式可以为网络设备生成该信号序列的方式，该第二QCL关系可以为上述多个OFDM符号上传输的多个信号序列之间的QCL关系，即该多个OFDM符号上传输的多个信号序列满足第二QCL关系。
需要说明的是，上述多个OFDM符号上传输的多个信号序列满足第二QCL关系也可以理解为：该多个信号序列或者该多个OFDM符号上的传输为相同的天线端口。
可选地，一种可能的实现方式，寻呼指示信号的信号序列可以为gold序列，m序列，zc序列，预定义序列等任意可能的序列。
可选地，另一种可能的实现方式，寻呼指示信号的信号序列可以为gold序列，m序列，zc序列，预定义序列中的多个序列的相乘得到的序列。
当然，实际实现时，寻呼指示信号的信号序列还可以为其它任意可能的序列，具体可以根据实际使用需求确定，本申请实施例不作限定。
可选地，本申请实施例中，在上述第二信息包括信号序列的生成方式的情况下，在上述步骤201a2之前，本申请实施例提供的信道检测方法还可以包括下述的步骤203。

信号序列指示是否检测寻呼下行控制信道；
检测寻呼下行控制信道的UE分组的索引；
传输信号序列的第一传输资源的索引；
UE驻留的小区编号；
网络设备发送寻呼指示信号的小区编号。
本申请实施例中，在上述第二信息包括信号序列的生成方式的情况下，UE可以先根据上述第三信息，确定信号序列的生成方式，从而可以根据第二信息，在第一传输资源上，接收寻呼指示信号的信号序列。
示例性的，以上述寻呼指示信号的信号序列为一个gold序列位列，该gold序列的初始化方式可以为：
Figure PCTCN2021120647-appb-000001
其中，
Figure PCTCN2021120647-appb-000002
表示一个1个slot内的symbol数，
Figure PCTCN2021120647-appb-000003
为slot索引，l为符号索引，i ssb为关联的SSB的索引。
一种实现方式，n ID用于指示UE是否需要在PO进行寻呼下行控制信道监听(即是否在PO中检测下行控制信道)。n ID＝0表示不监听寻呼下行控制信道；n ID＝1表示监听寻呼下行控制信道。或者n ID用于指示监听(即检测)寻呼下行控制信道的UE分组的索引。
可选地，本申请实施例中，在UE确定上述第一传输资源之后，UE可以确定该第一传输资源是否与执行其他事件(例如本申请实施例中的第一事件)的传输资源(例如本申请实施例中的第三传输资源)冲突(即在时域上存在交集或在时域上重叠)。如果第一传输资源与执行第一事件的第三传输资源在时域上重叠，那么择一执行下述的步骤201a3或步骤204。
步骤201a3、UE在第一传输资源与执行第一事件的第三传输资源在时域上重叠的情况下，在第一传输资源上，接收寻呼指示信号。
可选地，本申请实施例中，在上述第一传输资源中的N(正整数)个传输机会与上述第三传输资源在时域上重叠的情况下，若N小于第二阈值，则UE在第一传输资源上，接收寻呼指示信号。
相应的，当N大于或等于上述预设阈值时，UE可以不接收寻呼指示信号。例如UE可以在第三传输资源上执行第一事件。
可选地，本申请实施例中，上述N个传输机会可以为N个传输符号。
步骤204、UE在第一传输资源与执行第一事件的第三传输资源在时域上重叠的情况下，在第三传输资源上执行第一事件。
可以理解，由于上述步骤201a3与步骤204是择一执行的，那么若UE选择执行步骤201a3，则UE不再执行步骤204，若UE选择执行步骤204，则UE不再执行步骤201a3。
可选地，本申请实施例中，在UE选择执行步骤204的情况下，在UE执行上述第一事件之后，UE可以在上述K个PO中检测寻呼下行控制信道；或者UE可以不在该K个PO中检测寻呼下行控制信道。具体可以根据实际使用需求确定，本申请实施例不作限定。

步骤205、UE根据第一功率，确定寻呼指示信号的第二功率。
其中，上述第一功率可以为与寻呼指示信号关联的SSB的功率，或为与寻呼指示信号关联的寻呼下行控制信道的功率。
步骤201b、UE根据第二功率，接收网络设备发送的寻呼指示信号。
本申请实施例中，在UE接收网络设备发送的寻呼指示信号之前，UE可以根据与寻呼指示信号关联的SSB的功率或与寻呼指示信号关联的寻呼下行控制信道的功率(即上述第一功率)，确定寻呼指示信号的第二功率，从而UE可以根据寻呼指示信号的第二功率，接收网络设备发送的寻呼指示信号。
可选地，本申请实施例中，上述第二功率可以与第一功率相同；或者，
第二功率与第一功率的差值可以小于第一阈值；或者，
第二功率与第一功率的差值可以为预定义的值(即协议规定的值)或网络设备指示的值。
需要说明的是，本申请实施例中，上述“第二功率与第一功率的差值可以小于第一阈值”可以理解为第二功率与第二功率的差在一个预设范围内，例如[-x,+x]dB内。
可选地，本申请实施例中，对于寻呼指示信号和与寻呼指示信号关联的SSB或关联的寻呼下行控制信道，在每个资源单元上的能量(energy Per RE，EPRE)可以相同，或EPRE之间的差值在一个预设范围内。

其中，该第二事件可以包括无线资源管理(radio resource management，RRM)测量、在监听寻呼下行控制信道之前进行(automatic gain control，AGC)操作、时频同步中的至少一项。
可选地，本申请实施例中，在UE接收到上述寻呼指示信号之后，UE可以根据该寻呼指示信号，确定是否上述K个PO中检测寻呼下行控制信道，如果寻呼指示信号指示UE在该K个PO中检测寻呼下行控制信道，那么UE可以根据上述第二功率，检测寻呼下行控制信道，即UE根据该第二功率，接收寻呼下行控制信道。
本申请实施例提供一种信道检测方法，由于网络设备发送的寻呼指示信号，可以向UE指示是否在接收到该寻呼指示信号的下K个PO中检测下行控制信道，因此UE可以根据接收到的寻呼指示信号，确定是否检测下行控制信道，如此UE可以在寻呼指示信号指示的PO中检测下行控制信道，从而避免UE进行不必要的寻呼下行控制信道检测，进而减少UE的功耗浪费。
