本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE 802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。

请参见图1，图1示出本发明实施例可应用的一种无线通信系统的框图。无线通信系统包括用户设备(User Equipment，UE)11和网络侧设备12。其中，用户设备11也可以称作终端设备，用户设备11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等用户设备侧设备，需要说明的是，在本发明实施例中并不限定用户设备11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本发明实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站可在基站控制器的控制下与用户设备11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据 各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与用户设备11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从用户设备11到网络侧设备12)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络侧设备12到用户设备11)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
与以往的移动通信系统相比，未来5G移动通信系统需要适应更加多样化的场景和业务需求。5G的主要场景包括增强移动宽带(Enhanced Mobile Broadband，eMBB)，超高可靠与低时延通信(Ultra-reliable and Low Latency Communications,URLLC)，海量机器类通信(massive Machine Type of Communication，mMTC)，这些场景对系统提出了高可靠，低时延，大带宽，广覆盖等要求。
相关技术中，用户设备(User Equipment，UE)的最大监测物理下行控制信道(Physical Downlink Control Channel，PDCCH)候选数和非重叠(non-overlapped)控制信道粒子(Control Channel Element，CCE)数是每时隙(slot)，每子载波间隔(sub-carrier space，SCS)确定的。

对于URLLC业务，从降低时延角度，UE需要每span监测PDCCH，这对监测的PDCCH候选数和非重叠CCE数提出了更高的要求。
跨距(Span)定义如下：
对于PDCCH监测周期少于14个符号的情况，任何正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号可以监测PDCCH；
对于属于不同span的任何2个PDCCH监测时机(occasion)，它们中的至少一个不是FG-3-1的监测occasion，在相同或不同的搜索空间集(sss)中。
2个span的开始之间最小X OFDM符号间隔(包括跨slot边界情况)，每个span最长Y个连续OFDM符号(1个slot内)；
相邻Span不重叠；
每个span在一个slot内；
Slot内或跨slot，连续span的间隔可以不相同，但是所有span满足相同的[X,Y]；
每个监测occasion包含在1个span内；
为确定合适的span pattern，产生一个bitmap b(l),0<＝l<＝13。第一个span在b(l)＝1，从最小的l开始，下一个span从不在先前span的剩余的最小的l开始；
span持续期(duration)为max{all CORESET durations最大值,Y的最小值}(除了slot内最后一个pattern可能小于durations)。
如果UE配置了

个下行小区(cell)，SCS配置μ，且

那么UE每slot不要求监测多于

个PDCCH candidates或多于
Figure PCTCN2021085812-appb-000008
个non-overlapped CCEs。
目前的UE监测CCE数和盲检测数的确定是每slot定义的，无法适用于URLLC业务。
本发明实施例提供了一种基于跨距span进行PDCCH监测的监测数量的确定方法，应用于用户设备，如图2所示，包括：
步骤101：针对目标小区的目标span，确定与所述目标span对应的cell-span合并集合，所述cell-span合并集合包括多个非目标小区的span合并和所述目标小区的span合并，所述多个非目标小区的span与所述目标span在时域上重叠；其中，所述多个非目标小区和目标小区为网络侧为所述UE配置的基于span进行监测的小区；
步骤102：根据所述cell-span合并集合确定第一下行载波的数量以及第二下行载波的数量，所述第二下行载波为网络侧为所述UE配置的所有基于span进行监测的载波，所述第一下行载波为所述UE使用目标span进行基于span的PDCCH监测的载波；
此处的目标span合并是指目标span的span合并。
需要说明的是，由于上述非重叠CCE和PDCCH候选的计算是基于每个时隙，每个span计算的，因此，当计算一个span时，该span为目标span，其他时域重叠的span为非目标span，当计算另一个span时，待计算span为 目标span，其他时域重叠的span为非目标span。
步骤103：根据所述第一下行载波的数量以及第二下行载波的数量确定UE在所述目标span监测的非重叠的控制信道粒子CCE数和/或PDCCH候选数。
本实施例中，针对目标小区的目标span，确定与目标span对应的cell-span合并集合，cell-span合并集合包括多个非目标小区的span合并和目标小区的span合并，多个非目标小区和目标小区为网络侧为UE配置的基于span进行监测的小区，多个非目标小区的span与目标span在时域上重叠，根据cell-span合并集合确定第一下行载波的数量以及第二下行载波的数量，根据第一下行载波的数量以及第二下行载波的数量确定UE在目标span监测的非重叠的CCE数和/或PDCCH候选数，通过本实施例的技术方案，可以确定UE的监测数量，并且由于cell-span合并集合除包括目标小区的目标span合并外，还包括了非目标小区的span合并，这样即使有的时刻UE配置的非目标cell没有相应span，UE也可以把这部分处理能力用作目标cell的span，能充分利用UE每时刻的处理能力，提高UE的处理效率。
上述实施例中，所述第一下行载波的子载波间隔相同。
其中，所述第二下行载波的数量等于所述cell-span合并集合中所有span对应的cell数目；所述第一下行载波的数量等于所述cell-span合并集合中所有span对应的载波中第一载波的数量，第一载波的span合并与所述目标小区的span合并相同并且子载波间隔相同。
一些实施例中，如果对于子载波间隔μ，为UE配置有

个下行载波，这些载波中有
Figure PCTCN2021085812-appb-000010
个载波使用span合并(X,Y)进行PDCCH监测。在下行(downlink，DL)激活带宽部分(Bandwith part，BWP)使用子载波间隔μ，μ＝0,1分别对应15kHz和30kHz，且

其中，
Figure PCTCN2021085812-appb-000012
是UE支持的基于span进行PDCCH监测的载波数(即监测的cell数)。即UE被配置为所述基于span进行PDCCH监测的下行载波数大于UE支持的基于span进行PDCCH监测的载波数。

以图3为例，网络侧为UE一共配置3个cell：Cell1、Cell2和Cell3，子 载波间隔均为15kHz，即μ＝0。其中Cell 1的span合并为(2,2)，Cell 2和Cell 3的span合并为(4,3)。
对于Cell 1在一个slot内配置了7个span，具体地，这7个span是根据配置的PDCCH监测时机(monitoring occasion)确定该slot内的span图样(pattern)，在Cell 2和Cell 3一个slot内分别配置3个span，span pattern如图3所示。

以图5为例，网络侧为UE一共配置4个cell：Cell1、Cell2、Cell3和Cell4，子载波间隔为15kHz。其中Cell 1和Cell4的span合并为(2,2)，Cell 2和Cell 3的span合并为(4,3)。
对于Cell 1在一个slot内配置了7个span，具体地，这7个span是根据配置的PDCCH monitoring occasion确定该slot内的span图样(pattern)，在Cell 2和Cell 3一个slot内分别配置3个span，span pattern如图5所示。
对于Cell 1的span1，如图5所示，时域重叠span的cell-span合并集合 为{Cell 1(2,2)，Cell 2(4,3)，Cell 4(2,2)}，即重叠的cell数为3，即

对于每一调度小区，每一时隙的每个span，UE在子载波间隔为μ，span合并为(X，Y)时，在该span监测的非重叠的CCE的数目不大于
Figure PCTCN2021085812-appb-000046
和
Figure PCTCN2021085812-appb-000047

和
Figure PCTCN2021085812-appb-000049
中的最小值。
上述实施例中，如图3-图5所示，不同cell的符号边界对齐，即多个非目标小区的符号边界与目标小区的符号边界可以相同；在实际应用中，由于各个cell的部署(例如有的cell采用射频拉远头(Remote Radio Head，RRH)方式)，不同cell到UE的距离可能不同，因此信号到达UE端的时间可能不同(即从各cell接收信号的定时可能不同)，引起span的不对齐，即多个非目标小区的符号边界与所述目标小区的符号边界可以不同，如图6所示。
在不同cell的符号边界不对齐时，UE可根据每cell的实际定时确定每span的时域重叠情况，然后确定集合Q:{cell_1(X,Y) 1,Cell_2(X,Y) 2,…Cell_n(X,Y) n}
当然，UE还可以根据每cell的逻辑定时确定每span的时域重叠情况，然后确定集合Q。
可选地，网络侧可以配置具体采用哪一种方式确定集合Q。
一具体示例中，对于图7的Cell 2的第一个span的Q集合的确定，可以采用下述方式：
Set1的集合为{Cell 1(2,2)，Cell 2(4,3)}；
Set2的集合为{Cell 1(2,2)，Cell 2(4,3)，Cell 2(4,3)}；
之后通过Q＝set1∪set2以确定Q。
对于UE配置使用基于span的PDCCH监测(即第二通信协议的监测能力)的

个下行载波中，
Figure PCTCN2021085812-appb-000051

方式1：如果UE只有基于span的PDCCH监测(第二通信协议的监测能力，比如Rel-16的监测能力)，监测的CC数由pdcch-BlindDetectionCA-R16确定，即

Figure PCTCN2021085812-appb-000054
方式2：如果UE同时有基于slot的PDCCH监测(即第一通信协议的监测能力，比如Rel-15的监测能力)和基于span的PDCCH监测(第二通信协议的监测能力，比如Rel-16的监测能力)，对于基于span的PDCCH监测能 力的CC数由pdcch-BlindDetectionCA-R16确定，即
Figure PCTCN2021085812-appb-000055
Figure PCTCN2021085812-appb-000056
需要说明的是，对于时域重叠的span，如果span合并和子载波间隔相同，那么非重叠CCE和PDCCH候选数也相同，仅需计算一次即可，不需要对每个时域重叠的span，并且span合并和子载波间隔相同时，重复计算。
如图8所示，本发明实施例的用户设备200，包括监测数量的确定装置，能实现上述实施例中应用于用户设备的监测数量的确定方法，并达到相同的效果，该用户设备200具体包括以下功能模块：

需要说明的是，由于上述非重叠CCE和PDCCH候选的计算是基于每个时隙，每个span计算的，因此，当计算一个span时，该span为目标span，其他时域重叠的span为非目标span，当计算另一个span时，待计算span为目标span，其他时域重叠的span为非目标span。
处理模块230，用于根据所述第一下行载波的数量以及第二下行载波的数量确定UE在所述目标span监测的非重叠的控制信道粒子CCE数和/或PDCCH候选数。
