下面，对本申请的应用场景进行说明：
图1示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：终端10和网络设备20。
终端10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
接入网设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为网络设备。网络设备20与终端10之间可以通过空口建立连接，从而通 过该连接进行通信，包括信令和数据的交互。网络设备20的数量可以有多个，两个邻近的网络设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的网络设备20之间进行切换，也即与不同的网络设备20建立连接。
该接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点，发送接收点(Transmission Reception Point，TRP)等等。在采用不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR(New Radio，新的无线技术)系统中，称为gNodeB或者gNB。随着通信技术的演进，“网络设备”这一名称可能会变化。
核心网设备30是部署在核心网中的设备，核心网设备的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，5G NR系统中的核心网设备可以包括接入和移动性管理功能(Access and Mobility Management Function，AMF)网元、用户平面功能(User Plane Function，UPF)网元和会话管理功能(Session Management Function，SMF)网元等。示例性的，本申请实施例中的核心网设备30可以包括位置管理功能网元。可选地，位置管理功能网元包括位置服务器(location server)，位置服务器可以实现为以下任意一项：LMF(Location Management Function，位置管理网元)、E-SMLC(Enhanced Serving Mobile Location Centre，增强服务的流动定位中心)、SUPL(Secure User Plane Location，安全用户平面定位)、SUPL SLP(SUPL Location Platform，安全用户平面定位定位平台)。
网络设备包含核心网设备和接入网设备的至少一项。
图2示出了本申请一个示例性实施例提供的信号接收方法的流程图，示例性的可以应用于如图1所示的终端中，该方法包括以下内容中的至少部分内容：
步骤201：终端确定下行定位信号的第一时域位置以及除下行定位信号以外的其他下行传输的第二时域位置。
在本申请实施例中，网络设备不仅可以向终端发送下行定位信号，而且还会向终端发送除下行定位信号以外的其他下行传输。网络设备需要为终端配置用于传输下行定位信号的第一时域位置，而且还会为终端配置用于传输其他下行传输的第二时域位置。而对于终端来说，终端可以确定下行定位信号的第一时域位置以及除下行定位信号以外的其他下行传输的第二时域位置。
步骤202：终端根据第一时域位置和第二时域位置，以及冲突判断规则，确 定是否接收下行定位信号。
其中，该冲突判断规则包括第一时域位置和第二时域位置存在冲突和不存在冲突两种情况，该冲突判断规则用于终端确定在第一时域位置和第二时域位置是否存在冲突。
在一些实施例中，在终端处于RRC(Radio Resource Control，无线资源控制)idle(空闲态)的情况下，终端执行步骤201-202，以根据冲突判断规则确定是否接收下行定位信号。
在本申请实施例中，终端确定的下行定位信号的第一时域位置和其他下行传输的第二时域位置，而第一时域位置和第二时域位置之间的关系包括存在冲突和不存在冲突两种情况，终端需要根据冲突判断规则，确定下行定位信号与其他下行传输是否冲突。
需要说明的是，网络设备所执行的步骤可以单独形成一个实施例，终端所执行的步骤也可以单独形成一个实施例，本申请对此不作限定。
本申请实施例提供方案中，终端根据下行定位信号的第一时域位置和除下行定位信号以外的其他下行传输的第二时域位置，以及冲突判断规则，确定是否接收下行定位信号，提供了一种终端如何接收下行定位信号以及其他下行传输的方式，保证终端与网络设备之间进行数据传输的可靠性。
在图2所示的实施例的基础上，终端基于冲突判断规则和下行定位信号的优先级来确定是否接收下行定位信号。
在一些实施例中，终端响应于基于冲突判断规则确定下行定位信号与其他下行传输冲突，且在下行定位信号的优先级高于其他下行传输时，接收下行定位信号。或，在下行定位信号的优先级低于其他下行传输的优先级，不接收下行定位信号。
其中，该冲突判断规则用于根据第一时域位置和第二时域位置判断下行定位信号与其他下行传输是否冲突，并且在确定下行定位信号与其他下行传输冲突时，若下行定位信号的优先级高于其他下行传输的优先级，则终端优先接收下行定位信号。若下行定位信号的优先级低于其他下行传输的优先级，则终端优先接收其它下行传输。
需要说明的是，本申请实施例是以下行定位信号与其他下行传输冲突时，终端优先接收下行定位信号或其它下行传输为例进行说明。在另一实施例中， 若下行定位信号与其他下行传输不冲突时，终端接收下行定位信号和其他下行传输。
在图2所示的实施例的基础上，对于该冲突判断规则来说，包括多种方式来确定下行定位信号与下行传输是否冲突，该冲突判断规则包括以下至少一种情况：
第一种：在第一时域位置与第二时域位置存在重叠符号的情况下，确定下行定位信号与其他下行传输冲突。
在本申请实施例中，若第一时域位置与第二时域位置存在重叠符号，则说明下行定位信号和其他下行传输存在共用的时域位置，因此终端无法同时接收下行定位信号和其他下行传输，确定下行定位信号的与其他下行传输冲突。
例如，如图3所示，位于图3中的前面位置的为第一时域位置，位于图3中的后面位置的为第二时域位置，并且第一时域位置和第二时域位置中的阴影部分为第一时域位置与第二时域位置的重复部分，说明第一时域位置与第二时域位置存在重叠符号。
需要说明的是，本申请实施例是以第一时域位置与第二时域位置存在重叠符号为例进行说明。而在另一实施例中，若在第一时域位置与第二时域位置不存在重叠符号的情况下，确定下行定位信号与其他下行传输不冲突。
例如，如图4所示，位于图4中的前面位置的为第一时域位置，位于图4中的后面位置的为第二时域位置，并且第一时域位置和第二时域位置之间不存在重叠部分，说明第一时域位置与第二时域位置互不影响，第一时域位置与第二时域位置不存在重叠符号。
第二种：在第一时域位置与第一扩展时域存在重叠符号的情况下，确定下行定位信号与其他下行传输冲突。
其中，第一扩展时域包括第二时域位置、位于第二时域位置之前的X个符号或时隙、位于第二时域位置之后的Y个符号或时隙，其中X、Y为非负整数。
可选地，X和Y由通信协议规定，或者，X和Y由网络设备通过SIB(System Iformation Block，系统信息块)配置，或者，X和Y采用其他方式配置，本申请实施例不作限定。
其中，该第一扩展时域是对第二时域位置进行扩展以后得到的时域。例如，该第二时域位置包括第一起始位置和第一终止位置，将位于该起始位置之前的X 个符号或时隙的位置确定为第一扩展时域的第二起始位置，将位于第一终止位置之后的Y个符号或时隙的位置确定为第一扩展时域的第二终止位置，则第二起始位置与第二终止位置之间的时域为第一扩展时域。
例如，如图5所示，该第二时域位置之前存在X个符号，该第二时域位置之后存在Y个符号，该X个符号、第二时域位置和Y个符号的组合即为第一扩展时域。
可选地，该第一扩展时域包括第二时域位置、位于第二时域位置之前的X个符号、位于第二时域位置之后的Y个符号，其中X、Y为非负整数。或者，该第一扩展时域包括第二时域位置、位于第二时域位置之前的X个时隙、位于第二时域位置之后的Y个时隙，其中X、Y为非负整数。或者，该第一扩展时域包括第二时域位置、位于第二时域位置之前的X个符号、位于第二时域位置之后的Y个时隙，其中X、Y为非负整数。又或者，该第一扩展时域包括第二时域位置、位于第二时域位置之前的X个符号、位于第二时域位置之后的Y个时隙，其中X、Y为非负整数。
可选地，该第一扩展时域可以采用timewindow(时间窗口)表示，本申请实施例不作限定。
在本申请实施例中，若第一时域位置与第一扩展时域存在重叠符号，则说明下行定位信号和其他下行传输存在共用的时域位置，因此终端无法同时接收下行定位信号和其他下行传输，确定下行定位信号和其他下行传输冲突。
需要说明的是，本申请实施例是以第一时域位置与第一扩展时域存在重叠符号为例进行说明，而在另一实施例中，若在第一时域位置与第一扩展时域不存在重叠符号的情况下，确定下行定位信号与其他下行传输不冲突。
在一些实施例中，下行定位信号位于初始BWP(Bandwidth Part，带宽部分)内，或者，下行定位信号位于初始BWP外。
其中，该初始BWP为网络设备通过系统消息广播的方式为终端配置的BWP，或者，该初始BWP为网络设备与终端由协议约定的BWP，或者，该初始BWP为终端接收网络设备发送的SSB(Synchronization Signal/PBCH Block，同步信号块)对应的BWP，或者，该初始BWP还可以为采用其他方式配置的BWP，本申请实施例不作限定。
可选地，初始BWP外包括激活BWP，或者，包括默认BWP，或者包括其他类型的BWP，本申请实施例不作限定。
在本申请实施例中，若下行定位信号位于初始BWP内，则无需考虑BWP切换所需要的时长，而若下行定位信号位于初始BWP外，则需要考虑BWP切换所需要的时长，因此对于上述第一扩展频域，下行定位信号位于初始BWP内或初始BWP外时，X和Y可以存在不同的取值。
在一些实施例中，在下行定位信号位于初始BWP外的情况下，第一扩展时域包括第二时域位置、位于第二时域位置之前的第一数量的符号或时隙、位于第二时域位置之后的第二数量的符号或时隙，其中第一数量、第二数量为非负整数，在下行定位信号位于初始BWP内的情况下，第一扩展时域包括第二时域位置、位于第二时域位置之前的第三数量的符号或时隙、位于第二时域位置之后的第四数量的符号或时隙，其中第三数量、第四数量为非负整数；其中，第一数量不小于第三数量，第二数量不小于第四数量。
可选地，第一数量和第二数量可以相同，或者也可以不同。第三数量和第四数量可以相同，或者也可以不同。另外，由于第一数量不小于第三数量，第二数量不小于第四数量，则第一数量、第二数量、第三数量和第四数量也可以相同，或者，也可以不同。
例如，在下行定位信号位于初始BWP外的情况下，第一扩展时域包括第二时域位置、位于第二时域位置之前的5个符号、位于第二时域位置之后的6个符号，在下行定位信号位于初始BWP内的情况下，第一扩展时域包括第二时域位置、位于第二时域位置之前的4个符号、位于第二时域位置之后的4个符号。

在本申请实施例中，若第一时域位置与第一扩展时域存在重叠符号，则说明下行定位信号和服务小区对应的下行信道和/或下行信号存在共用的时域位置，因此终端无法同时接收下行定位信号和服务小区对应的下行信道和/或下行信号，而且由于下行定位信号的优先级低于服务小区对应的下行信道和/或下行信号的优先级，因此终端接收服务小区对应的下行信道和/或下行信号。
需要说明的是，本申请实施例是以第一时域位置与第一扩展时域存在重叠 符号为例进行说明，而在另一实施例中，若在第一时域位置与第一扩展时域不存在重叠符号的情况下，确定下行定位信号与服务小区对应的下行信道和/或下行信号不冲突，终端可以接收下行定位信号和服务小区对应的下行信道和/或下行信号。

在本申请实施例中，若第一时域位置与第一扩展时域存在重叠符号，则说明下行定位信号和第一异频邻小区对应的下行信道和/或下行信号存在共用的时域位置，因此终端无法同时接收下行定位信号和第一异频邻小区对应的下行信道和/或下行信号，而且由于下行定位信号的优先级低于第一异频邻小区对应的下行信道和/或下行信号的优先级，因此终端接收第一异频邻小区对应的下行信道和/或下行信号。
