图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，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、发送接收点(TransmittingReceivingPoint，TRP)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，在本申请实施例中仅以5G NR系统中的基站为例，但是并不限定基站的具体类型。
如图2所示，为本申请一示例性实施例提供的确定目标时域位置的方法200的流程示意图，该方法200可应用但不限于通信设备，具体可由安装于所述通信设备中的软件和/或硬件实现。可选地，所述通信设备可以是终端，也可以是网络侧设备，例如基站。所述确定目标时域位置的方法200至少可以包括如下步骤。
S210，在多个不同的SSB与Type 0PDCCH发生复用，且所述SSB的SCS不大于所述Type 0PDCCH的SCS的情况下，根据目标帧结构确定目标时域位置信息。
其中，前述SSB与Type 0PDCCH(也即，Coreset 0)发生复用的复用方式可以是Pattern2和/或Pattern3。
具体来讲，在5G NR系统中，时域长度为10ms的无线帧内，每个无线帧被分为10个同样大小的长度为1ms的子帧，由于SCS不同，每个子帧可以包含多个时隙，每个时隙由一定数量的符号(Symbol)构成，且符号个数由循环前缀(Cyclic Prefix，CP)类型决定。另外，NR系统支持多波束的同步信号、辅同步信号和物理广播信道发送，其中，对于具有SSB的半帧(5ms)，候选SSB的数目和第一个符号索引位置可根据SSB的SCS确定。例如，以下CaseD、Case E是针对半帧而言。
CaseD-120KHz SCS：候选SSB的第一个符号的索引为{4，8，16，20}+28*n，对于F>6GHz，n＝0，1，2，3，5，6，7，8，10，11，12，13，15，16，17，18(1ms内8个slot，1个slot内2个SSB，1ms占16个SSB，共4组，则4ms内Lmax＝64)，其中，Lmax表示SSB对应的波束(beam)总数。
CaseE-240KHz SCS：候选SSB的第一个符号的索引为{8，12，16，20， 32，36，40，44}+56*n，对于F>6GHz，n＝0，1，2，3，5，6，7，8(1ms内16个slot，1个slot内2个SSB，1ms占32个SSB，共2组，则2ms内Lmax＝64)其中，Lmax表示SSB对应的波束(beam)总数。
此外，因为SSB的内部结构是通信协议标准化的，因此，当通信设备在特定的同步频点搜到SSB后，可以尝试对SSB进行解码。其中，SSB里面包含的重要的信息是主信息块(Master Information Block，MIB)，而MIB中携带了用于调度剩余最小信息块(Remaining Minimum SI，RMSI)的PDCCH的相关配置信息，以帮助用户确认RMSI PDCCH资源配置和监控PDCCH的时机，其中，如图3a、图3b、图3c所示，PDCCH所在的RMSI CORESET和SSB之间存在如下三种相对关系。
Pattern1：SSB和与其对应的RMSI CORESET TDM(时分复用)。
Pattern2：SSB和与其对应的RMSI CORESET FDM(频分复用)。
Pattern3：SSB和与其对应的RMSI CORESET FDM。
在本步骤中，多个不同的SSB与Type 0PDCCH发生复用的复用方式可以是Pattern2和/或Pattern3。
目标时域位置信息是目标SSB对应的Type 0PDCCH所在的时域位置信息(如时隙的索引、系统帧的索引等)，以用于在所述目标时域位置信息对应的时域位置上监听目标SSB对应的Type 0 PDCCH。所述目标SSB可以是所述通信设备接收到的网络侧设备发送的多个SSB中的任意一个。
可选地，在进行目标时域位置信息确定时，所述目标帧结构可以是预先设定的帧结构，也可以是基于所述Type 0PDCCH的SCS确定的帧结构，或者是基于所述SSB的SCS确定的帧结构等，本实施例在此不做限制。
本实施例给出的前述确定目标时域位置的方法200中，在多个不同的SSB与Type 0 PDCCH发生复用，且所述SSB的SCS不大于所述Type 0PDCCH的SCS的情况下，通信设备基于目标帧结构确定目标SSB对应的Type 0PDCCH所在的时域位置信息，由此，能够准确地定位目标SSB对应的Type 0PDCCH所在的时域位置信息，以监听Type 0PDCCH。
如图4所示，为本申请一示例性实施例提供的确定目标时域位置的方法400的流程示意图，该方法400可应用但不限于通信设备，具体可由安装于所述通信设备中的软件和/或硬件实现。可选地，所述通信设备可以是终端，也可以是网络侧设备。所述确定目标时域位置的方法400至少可以包括如下步骤。

其中，S410除可参照前述S210的描述之外，作为一种实现方式，再次参阅图4，S410中所述的根据目标帧结构确定目标时域位置信息的过程可以包括S420和S430。
S420，根据目标帧结构确定候选时域位置信息。

其中，所述预设偏移值根据以下(1)-(3)中的至少一项确定。
(1)预定值。在一种实现方式中，所述预定值可以为0、1、2等。
(2)通过网络侧设备配置得到。
(3)根据目标SSB的索引确定得到。一种实现方式中，可以根据SSB的索引预先配置不同的预设偏移值，以用于根据该预设偏移值确定SSB实际映射的Type 0 PDCCH的时域位置。
一种实现方式中，通信设备可同时在所述候选时域位置信息对应的时域位置、以及偏移后的时域位置上监听所述目标SSB对应的Type 0 PDCCH，以进一步提高监听的准确性。
本实施例给出的前述确定目标时域位置的方法400中，在多个不同的SSB与Type 0 PDCCH发生复用，且所述SSB的SCS不大于所述Type 0PDCCH的SCS的情况下，基于目标帧结构确定目标SSB对应的Type 0PDCCH所在的候选时域位置信息，并在所述候选时域位置信息对应的时域 位置的基础上偏移一预设偏移值，以在偏移后的时域位置上监听SSB对应的Type 0PDCCH，由此，能够进一步准确地定位SSB对应的Type 0PDCCH所在的时域位置信息，实现对Type 0PDCCH的监听。
如图5所示，为本申请一示例性实施例提供的确定目标时域位置的方法500的流程示意图，该方法500可应用但不限于通信设备，具体可由安装于所述通信设备中的软件和/或硬件实现。可选地，所述通信设备可以是终端，也可以是网络侧设备。再次参阅图5，所述确定目标时域位置的方法500至少可以包括如下步骤。

其中，S520和S530中是以Type 0 PDCCH的SCS确定的目标帧结构为基准，确定目标时域位置信息，进而使得通信设备可基于目标时域位置信息对应的目标时域位置监听Type 0 PDCCH。
在一种实现方式中，如图6a所示，对于Pattern 2 case D的场景，假设 Type 0 PDCCH的SCS与SSB的SCS一致(相等)，目标SSB为
