具体实施方式
下面将结合附图对本申请实施例中的技术方案进行描述。
可以理解，本申请的技术方案可具体应用于各种通信系统中，例如，第五代移动通信(the 5th Generation，5G)系统如新无线/新空口(New Radio，NR)系统、长期演进(Long Term Evolution，缩写：LTE)系统或未来通信系统等，本申请不做限定。
请参见图1，是本申请提供的一种通信系统的架构图。如图1所示，该通信系统可以包括：一个或多个基站101，一个或多个终端102，以及，一个或多个位置管理网元103。图1中仅示出两个基站101、一个终端102和一个位置管理网元103。该基站101、终端102和位置管理网元103之间可以进行信息传输。
在本申请中，位置管理网元可用于位置管理，包括获取PRS参数，和/或，传输PRS参数等等。例如，该位置管理网元可以为位置管理功能(Location Management Function，LMF)，还可以为用于位置管理的其他网元，本申请不做限定。
在本申请中，基站可以用于与一个或多个终端进行通信，也可以用于与位置管理网元进行通信，还可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站之间的通信)。基站可以是长期演进(Long Term Evolution，LTE)系统中的演进型基站(Evolutional Node B，eNB)，还可以是5G系统、NR系统中的基站gNB，等等，此处不一一列举。或者，该基站101还可以是指传输点(transmission point，TP)、接入点(Access Point，AP)、收发点(transmission and receiver point，TRP)、中继设备、中心单元(Central Unit，CU)，或者具备基站功能的其他设备等等。
在本申请中，终端可以是具有通信功能的设备，例如可以是车载设备、可穿戴设备、手持设备(如智能手机)等。该终端还可以叫做其余名称，比如用户设备(User Equipment，UE)、用户单元、移动台(mobile station)、移动单元(mobile unit)、终端设备、通信设备等等，本申请不做限定。
在通信系统中，经常存在需要对终端或其他设备进行定位的场景，定位技术也得到较快发展。例如，定位技术可包括：基于GNSS提供户外场景中的位置信息的定位技术；基于无线电技术的定位技术(如在LTE网络中，提供多种选项来定位用户、无线网络、地面信标系统，等等)；基于惯性测量单元(Inertial Measurement Units，IMU)的定位技术；基于传感器的定位技术(如基于加速计追踪用户位置，利用陀螺仪、磁力仪或利用大气压力传感器进行垂直定位)；基于OTDOA、UTDOA、Cell-ID(with cell portion ID)或E-Cell-ID的定位技术；基于LPP的RAT-independent定位技术，基于NR standalone RAT-dependent定位技术，包括基于DL-TDOA、DL-AoD、UL-TDOA、UL-AoA、RTT以及E-CID的定位技术，等等。例如，3GPP NR可基于OTDOA和UTDOA、Cell-ID或E-Cell-ID等定位技术，利用大带宽(低频段以及高频段)进行时间测量，以实现用户定位，从而提升定位性能；还可利用大规模天线系统(massive MIMO)，结合时间测量以及传播信道的空间和角度域，来实现更准确的用户定位。
定位参考信号(Positioning Reference Signal，PRS)是一种用于实现定位的参考信号。终端可基于网络侧发送的PRS测量到达时间、信号强度、到达倾角等信息，以基于这些信息确定终端的位置，实现定位。例如，终端可以基于这些信息确定自身的位置并上报网络，又如，终端可以将这些信息上报网络，以使网络侧基于这些信息确定出终端位置，从而实现定位。其中，PRS的发送可以由LMF进行配置，比如采用周期性的配置。然而，周期性的发送PRS可能存在资源利用率低的问题，资源消耗较大。而本申请的PRS发送能够按需进行，相比周期性发送，能够实现快速的、即时的PRS发送，由此有助于提升资源利用率，提升定位灵活性，并有助于降低网络功耗。例如，本申请可通过位置管理网元如LMF获取第一PRS参数，即非周期性发送的PRS的参数，进而向终端发送该第一PRS参数，以便于基 于该非周期性发送的PRS的参数实现定位。又如，本申请还可通过位置管理网元如LMF向至少一个基站发送PRS触发指示，触发基站发送PRS，以实现定位。又如，本申请还可通过位置管理网元获取第一PRS参数，并通过向至少一个基站发送PRS触发指示，以触发基站根据该第一PRS参数发送PRS，以实现定位。
在本申请中，PRS参数还可叫做其余名称，比如PRS信息、PRS触发参数等等，本申请不做限定。PRS触发指示还可叫做PRS指示、触发指示、PRS发送指示、发送指示等等，本申请不做限定。
可以理解，非周期性发送的PRS与周期性发送的PRS不同，即非周期性发送的PRS的参数和周期性发送的PRS的参数不同。例如，相比于周期性发送的PRS，非周期性发送的PRS在时间资源属性上存在不同。可选的，该非周期性发送的PRS还可以叫做非周期PRS、非周期性的PRS或者其余名称；相应的，周期性发送的PRS还可以叫做周期PRS、周期性的PRS或者其余名称。非周期性发送的PRS的参数还可称为非周期PRS参数、非周期PRS的参数、PRS灵活触发参数等等，周期性发送的PRS的参数还可称为周期PRS参数、周期PRS的参数、PRS周期触发参数等等，本申请不做限定。

可选的，该PRS触发指示可包括以下信息中的任一项或多项：PRS资源类型、PRS空间关系信息、PRS资源配置信息等等，此处不赘述。可以理解，LMF向各基站发送的PRS触发指示所携带的参数可以不同，如向服务基站发送PRS触发指示所携带的信息和向邻基站发送PRS触发指示所携带的信息存在不同。例如，两者的PRS资源配置信息不同。
在可能的实施方式中，基站在接收到PRS触发指示之后，还可向LMF回复响应消息。例如，服务基站向LMF发送响应消息，邻基站向LMF发送响应消息。
可以理解，步骤7102和步骤7103的执行顺序不受限制，比如还可先执行步骤7103，再执行步骤7102，或者步骤7102和步骤7103可同时执行，本申请不做限定。
7104、服务基站发送PRS。
7105、邻基站发送PRS。
可选的，服务基站在接收到PRS触发指示之后，可发送PRS；邻基站在接收到PRS触发指示之后，可发送PRS。该PRS可以为非周期PRS。
在可能的实施方式中，如果UE通过服务基站上报PRS触发请求，LMF可不再向服务基站发送PRS触发指示，而仅向其余基站如邻基站发送PRS触发指示，以触发邻基站发送PRS。服务基站可直接根据来自UE的PRS触发请求发送PRS。
在可能的实施方式中，基站发送PRS时，可发送预设的PRS；也可以按照PRS触发指示中携带的信息确定PRS后发送PRS，本申请不做限定。例如，服务基站和邻基站可分别基于各自接收到的PRS触发指示所携带的信息，确定PRS，并发送该PRS。
可选的，LMF可以向每个基站发送一个PRS触发指示，也可以发送多个PRS触发指示，每个PRS触发指示所携带的参数可以不同。进而基站可以根据LMF发送的PRS触发指示发送一个或多个PRS。例如，如果LMF向服务基站发送一个PRS触发指示，服务基站可根据该PRS触发指示发送一个PRS；例如，如果LMF向邻基站发送多个PRS触发指示，邻基站可根据该多个PRS触发指示发送一个或多个PRS。
在可能的实施方式中，服务基站和邻基站在发送PRS之后，可向LMF回复响应消息，以指示PRS 的发送。
可以理解，步骤7103和步骤7104的执行顺序不受限制，比如还可先执行步骤7104，再执行步骤7103，本申请不做限定。
在本实施例中，UE可通过向LMF发送PRS触发请求，使得LMF向各基站发送PRS触发指示，以触发基站发送PRS，以便于基于该PRS实现定位，由此能够实现基于需求灵活触发PRS发送，这就提升了资源利用率，提升了定位灵活性。
请参见图7b，图7b是本申请实施例提供的又一种信息传输方法的交互示意图。在本实施例中，以位置管理网元为LMF，基站包括服务基站和一个邻基站，终端为UE为例，LMF可通过向各基站发送PRS触发指示，以指示基站发送PRS，并可向UE发送通知消息，以告知UE该PRS的发送。如图7b所示，该方法可以包括以下步骤：
7201、LMF向服务基站发送PRS触发指示。
7202、LMF向邻基站发送PRS触发指示。
LMF可分别向各基站发送PRS触发指示，以指示各基站发送PRS。可选的，LMF可以在有UE定位需求时向各基站发送触发指示。例如，LMF可在接收第三方发送的UE位置获取请求时，向各基站发送触发指示。
可选的，该PRS触发指示可包括以下信息中的任一项或多项：PRS资源类型、PRS空间关系信息、PRS资源配置信息等等，此处不赘述。
进一步可选的，LMF可以向每个基站发送一个PRS触发指示，也可以发送多个PRS触发指示，此处不赘述。
可以理解，步骤7201和步骤7202的执行顺序不受限制，比如还可先执行步骤7202，再执行步骤7201，或者步骤7201和步骤7202可同时执行，本申请不做限定。
7203、服务基站发送PRS。
7204、邻基站发送PRS。
可选的，服务基站在接收到PRS触发指示之后，可发送PRS；邻基站在接收到PRS触发指示之后，可发送PRS。该PRS可以为非周期PRS。
在可能的实施方式中，基站发送PRS时，可发送预设的PRS；也可以按照PRS触发指示中携带的信息确定PRS后发送PRS，此处不赘述。
7205、服务基站向LMF发送响应消息。
7206、邻基站向LMF发送响应消息。
可选的，服务基站和邻基站在发送PRS之后，可向LMF回复响应消息，以指示PRS的发送。或者，服务基站和邻基站可以接收到PRS触发指示之后，向LMF回复响应消息。
可以理解，上述各过程的序号的大小并不意味着限制执行顺序的先后。例如，还可先执行步骤7203，再执行步骤7202；又如，还可先执行步骤7205，再执行步骤7203，等等，此处不一一列举。
7207、LMF向UE发送通知消息。
例如，LMF向服务基站发送的PRS触发指示为on-demand PRS trigger for serving，向邻基站发送的第一消息为on-demand PRS trigger for neighbor，服务基站向LMF发送的响应消息为on-demand PRS trigger response for serving，邻基站向LMF发送的请求响应消息为on-demand PRS trigger response for neighbor，LMF向UE发送的通知消息为on-demand PRS indication。
例如，服务基站可在向服务基站和邻基站发送PRS触发指示之后，向UE发送通知消息；又如，LMF可在接收到服务基站和邻基站回复的响应消息之后，向UE发送通知消息，以指示PRS的发送。以便于UE及时接收PRS，从而有助于提升PRS接收的可靠性。
在本实施例中，LMF可通过向各基站发送PRS触发指示，以指示基站发送PRS，并在接收到基站回复的响应消息之后，向UE发送通知消息，以告知UE该PRS的发送，以便于UE及时接收PRS，基于该PRS实现定位，由此能够实现基于需求灵活触发PRS发送，这就提升了资源利用率，提升了定位 灵活性，且有助于降低系统功耗。
可以理解，图5至图7b示出的方案还可以与图2至图4c示出的方案进行结合，如位置管理网元可获取第一PRS参数后，向至少一个基站发送PRS触发指示，以触发基站根据该第一PRS参数发送PRS，等等，此处不赘述。
可以理解，上述方法实施例都是对本申请的信息传输方法的举例说明，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
