这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
本公开提供一种定位用途参考信号传输方法，该方法可以应用于图1所示的无线通信系统中，如图1所示，终端通过诸如基站等无线接入网网络设备接入到无线接入网中，无线接入网网络设备与核心网网络设备完成数据的回传和前向传递，以进行各种通信服务。
可以理解的是，无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、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 FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络或系统。本公开中网络可包括无线接入网(Radio Access Network，RAN)以及核心网(Core Network，CN)。网络中包括有网络设备，该网络设备例如可以是无线网络设备、核心网设备等。其中，无线网络设备也可以称为基站。网络可以通过网络设备为终端提供网络服务，不同的运营商可以为终端提供不同的网络服务，也可以理解为不同的运营商对应有不同的运营商网络。例如，5G NR中，无线网络设备即无线接入网设备可以称为gNB。gNB还可以体现为至少一个发送接收点(Transmission Reception Point，TRP)。核心网设备包括一种位置管理功能网元。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)。
终端(Terminal)，有时称为移动台(Mobile Station，MS)，也可以称为用户设备(User Equipment，UE)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数 据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。本公开实施例中以下以终端称为UE为例进行说明。
5G R16引入了多种定位技术，可以实现对UE的定位。对于其中一些定位技术，基于定位用途参考信号进行定位。相关技术中，每个定位用途参考信号占用一个频域层(frequency layer)进行传输。然而，一个frequency layer可能会存在不能达到足够定位精度的问题。如何进行定位用途参考信号的传输，以提高定位精度，是需要解决的问题。
有鉴于此，本公开实施例提供一种定位用途参考信号传输方法，通过载波聚合的方式进行定位用途参考信号传输，以提高定位精度。
其中，本公开实施例中涉及的定位用途参考信号可以包括诸如PRS等下行定位用途参考信号，也可以包括诸如SRS等上行定位用途参考信号，当然还可以是其他定位用途参考信号，例如后续新引入的定位用途参考信号。
图2是根据一示例性实施例示出的一种定位用途参考信号传输方法的流程图，该定位用途参考信号传输方法可以单独被实施，也可以结合本公开其他实施例一同被实施。如图2所示，定位用途参考信号传输方法用于终端中，包括以下步骤。
在步骤S11中，获取第一信息，第一信息用于指示传输定位用途参考信号的第一载波组，第一载波组中包括至少两个载波。
本公开实施例中，第一信息可以理解为是定位用途参考信号的配置信息。该第一信息中包括有传输定位用途参考信号所需的载波信息。
其中，本公开实施例中第一信息指示的载波信息中包括有为传输定位用途参考信号所配置的载波组，以下称为第一载波组。其中，第一载波组中包括有多个载波，也可以理解为是包括至少两个载波。
本公开实施例中，终端获取的第一信息中包括有第一载波组，该第一载波组中包括有多个载波，进而可以基于该多个载波采用载波聚合的方式进行定位用途参考信号的传输，相对采用单载波方式传输定位用途参考信号，可以提高定位精度。
本公开实施例提供的定位用途参考信号传输方法，可以基于定位用途参考信号相对传输其他信道/信号的传输优先级，进行传输。
本公开实施例中涉及的其他信道/信号可以是以下至少之一：
服务小区的同步广播信号块(Synchronization Signal and PBCH block，SSB)，邻小区的SSB，超可靠和低时延通信(Ultra-Reliable and Low Latency Communications，URLLC) 业务的物理下行控制信道(Physical downlink control channel，PDCCH)和/或物理下行共享信道(Physical downlink shared channel，PDSCH)，不同于URLLC业务的其他业务的PDCCH和/或PDSCH，解调参考信号(Demodulation Reference Signal，DMRS)，信道状态信息(Channel State Information，CSI)-参考信号(Reference Signal，RS)，物理上行控制信道(Physical uplink control channel，PUCCH)和/或物理上行共享信道(Physical uplink shared channel，PUSCH)，以及物理随机接入信道(Physical Random Access Channel，PRACH)。
进一步的，本公开实施例一种实施方式中，第一信息可以由位置管理功能网元(Location Management Function，LMF)等核心网设备配置并发送。终端接收LMF等核心网设备发送的第一信息，并基于第一信息确定传输定位用途参考信号的第一载波组。
其中，定位用途参考信号相对传输其他信道/信号的传输优先级可以是由网络设备来指示的，以下将指示传输定位用途参考信号相对其他信道/信号传输优先级的信息，称为第二信息。
图3是根据一示例性实施例示出的一种定位用途参考信号传输方法的流程图，该定位用途参考信号传输方法可以单独被实施，也可以结合本公开其他实施例一同被实施。如图3所示，定位用途参考信号传输方法用于终端中，包括以下步骤。
在步骤S21中，接收第二信息，第二信息用于指示至少两个载波中各载波传输定位用途参考信号相对传输其他信道/信号的优先级。
本公开实施例中，终端接收的第二指示信息中指示定位用途参考信号相对其他信道/信号的传输优先级，进而可以基于该优先级进行定位用途参考信号的传输。
其中，若定位用途参考信号的优先级高于其他信道/信号的优先级，则在定位用途参考信号与其他信道/信号在时域位置上重叠时，可以优先传输定位用途参考信号。或者其他信道/信号在时域上传输所占用的时域位置，在定位用途参考信号传输时域位置的前后时，可以优先传输定位用途参考信号。进一步的，对于其他信道/信号的传输可以舍弃，或者后续再进行传输。
本公开实施例中，终端可以接收用于配置第一载波组的第一信息，并接收第二信息，该第二信息中指示第一载波组中各载波传输定位用途参考信号相对其他信道/信号的优先级，进而终端可以在多载波传输定位用途参考信号时，基于各载波自身传输定位用途参考信号的优先级，进行定位用途参考信号的传输。
本公开实施例一种实施方式中，第二信息可以由gNB等无线接入网设备配置并发送。终端接收无线接入网设备发送的第二信息，并基于第二信息确定第一载波组中各载波传输定位用途参考信号相对其他信道/信号的优先级。
本公开实施例以下，对定位用途参考信号的优先级实施方案进行说明。
一种实施方式中，定位用途参考信号在至少两个载波中各个载波上传输的优先级相同，即第一载波组中所有载波上传输定位用途参考信号的优先级相同。以下行定位用途参考信号为例，一方面，若定位用途参考信号的优先级低于其他信道/信号的优先级时，在发生传输冲突时，终端在该第一载波组中的所有载波都不能接收定位用途参考信号。另一方面，若定位用途参考信号的优先级高于其他信道/信号的优先级时，在发生传输冲突时，终端在该第一载波组中的所有载波都可以接收定位用途参考信号。
另一种实施方式中，定位用途参考信号在至少两个载波中不同载波上传输的优先级不同，即第一载波组中存在有传输定位用途参考信号的优先级不同的载波。例如，一示例中，针对PRS优先级，与URLLC业务的PDCCH和/或PDSCH的优先级，在不同的载波上可以是不一样的。比如，第一载波组中包括载波1和载波2，在载波1上PRS优先级高于URLLC业务的PDCCH和/或PDSCH的优先级。在载波2上，PRS优先级低于URLLC业务的PDCCH和/或PDSCH的优先级，但高于其他业务的PDCCH和/或PDSCH的优先级。
其中，由于定位用途参考信号在不同载波上传输的优先级不同，故，本公开实施例中为高精度的进行定位，在进行定位用途参考信号传输时，可以在第一载波组中确定优先级高于传输其他信道/信号优先级的载波，进行定位用途参考信号传输。
图4是根据一示例性实施例示出的一种定位用途参考信号传输方法的流程图，该定位用途参考信号传输方法可以单独被实施，也可以结合本公开其他实施例一同被实施。如图4所示，定位用途参考信号传输方法用于终端中，包括以下步骤。
在步骤S31中，在第一载波组中确定第二载波组，第二载波组中各载波传输定位用途参考信号的优先级高于传输其他信道/信号的优先级。
进一步的，本公开实施例中，在确定了优先级高于传输其他信道/信号优先级的第二载波组后，终端可以基于该第二载波组进行定位用途参考信号的传输。
其中，本公开实施例中，终端可进一步确定是否在确定的第二载波组上进行定位用途参考信号的传输。例如，终端可以确定是否在第二载波组上接收PRS。或者终端可以确定是否在第二载波组上发送SRS。
本公开实施例中，确定是否在第二载波组上进行定位用途参考信号传输的条件包括用于确定传输定位用途参考信号的条件或包括用于不传输定位用途参考信号的条件，基于该条件确定是否在第二载波组上进行定位用途参考信号传输。
其中，本公开实施例中可以确定传输定位用途参考信号的条件包括如下至少一项：
A：第二载波组的载波带宽和，大于或等于第一门限。
B：第二载波组的载波带宽和，与第一载波组的载波带宽和之间的比值大于或等于第二门限值。
C：第二载波组中载波之间的间隔数，小于或等于第三门限值。
D：第二载波组中载波之间的频域间隔值，小于或等于第四门限值。
E：第二载波组中存在有终端支持的用于传输定位用途参考信号的载波组合。
或者，本公开实施例中也可确定不传输定位用途参考信号的条件，例如，不传输定位用途参考信号的条件可以包括如下至少一项：
A：第二载波组的载波带宽和，小于第一门限。
B：第二载波组的载波带宽和，与第一载波组的载波带宽和之间的比值小于第二门限值。
C：第二载波组中载波之间的间隔数，大于第三门限值。
D：第二载波组中载波之间的频域间隔值，大于第四门限值。
E：第二载波组中存在有终端不支持的用于传输定位用途参考信号的载波组合。
一种实施方式中，响应于终端确定满足传输定位用途参考信号的条件，通过第二载波组传输定位用途参考信号。或者，响应于终端确定不满足不传输定位用途参考信号的条件，通过第二载波组传输定位用途参考信号。
另一种实施方式中，响应于终端确定满足不传输定位用途参考信号的条件，停止通过第二载波组传输定位用途参考信号。或者响应于终端确定不满足传输定位用途参考信号的条件，停止通过第二载波组传输定位用途参考信号。
本公开实施例中上述用于确定是否在第二载波组上进行定位用途参考信号传输时涉及的第一门限值，第二门限值，第三门限值和第四门限值中的至少一项，可以采用以下方法之一确定：
方法一：接收LMF等核心网设备发送的指示信息，并基于接收的LMF等核心网设备发送的指示信息确定。该LMF等核心网设备发送的指示信息中可以指示相应的门限值。
方法二：接收无线接入网设备发送的指示信息，并基于接收的无线接入网设备发送的指示信息确定。该无线接入网设备发送的指示信息中可以指示相应的门限值。
方法三：基于终端存储的门限值确定。一示例中，可以基于协议规定门限值的默认值，终端将该门限值的默认值保存在终端芯片中。
本公开实施例中，在基于载波组合方式确定是否在第二载波组上进行定位用途参考信号传输时，终端可以基于支持或不支持的载波组合，确定是否在第二载波组上进行定位用途参考信号传输。比如终端上报多种可以支持的载波组合，或上报多种不支持的载波组合， 比如有按照从低频到高频排序的载波C1，C2……C10。终端上报可以支持的组合为：C1C2，C1C2C3，C1C3，C1，C3C4……。
进一步的，本公开实施例中，终端可以自行选择支持的载波组合，并向LMF等核心网设备或无线接入网设备发送终端支持的用于传输定位用途参考信号的至少一个载波组合信息。其中，载波组合信息包括载波组合标识或载波组合包含的各个载波的载波标识。
一示例中，终端支持C1C2或C2C4，不支持C1C2C4，但是由于优先级的影响，能进行定位用途参考信号传输的载波组合为C1C2C4，那么终端可以自己选择是测量C1C2还是C2C4，并将选择的载波组合信息上报；或者是终端根据C1C2和C2C4的带宽大小来确定选择测量C1C2还是C2C4。
可以理解的是，本公开上述各实施例中涉及的定位用途参考信号可以是下行定位用途参考信号，也可以是上行定位用途参考信号。
本公开实施例以下，分别针对下行定位用途参考信号以及上行定位用途参考信号的传输进行说明。
一种实施方式中，定位用途参考信号包括下行定位用途参考信号。该下行定位用途参考信号包括PRS或其他下行定位用途参考信号，比如可能后续新引入的下行定位用途参考信号。

在步骤S42中，进行下行定位用途参考信号的测量，并上报测量结果以及第二载波组信息。
其中，第二载波组信息包含载波组标识或第二载波组包含的各个载波的载波标识。
一示例中，终端确定在第二载波组的各个载波上接收测量PRS。终端进行PRS测量，之后上报测量结果以及第二载波组信息。
其中，第二载波组信息中的载波组标识或载波标识也可以由gNB等无线接入网设备在指示给终端各个载波上定位用途参考信号优先级(第二信息)的同时或前后告知LMF等核心网设备。
另一种实施方式中，定位用途参考信号包括上行定位用途参考信号。该上行定位用途参考信号包括SRS或其他上行定位用途参考信号，比如可能后续新引入的上行定位用途参考信号。

在步骤S51中，通过第二载波组中的各个载波发送上行定位用途参考信号。
本公开实施例中，终端通过第二载波组中的各个载波发送上行定位用途参考信号。无线接入网设备即TRP可以接收该上行定位用途参考信号，并进行上行定位用途参考信号的测量，以及测量结果的上报。
其中，本公开实施例中，对于上行定位用途参考信号的优先级相对较低的情况下，网络设备后续也可无需基于该优先级较低的上行定位用途参考信号进行定位，终端可以不进行上行定位用途参考信号的发送，以节省通信开销。
本公开实施例提供的定位用途参考信号传输方法，基于载波聚合方式传输定位用途参考信号。并通过对载波聚合的各载波上定位用途参考信号传输优先级的指示，基于该传输优先级进行定位用途测量参考信号的测量以及测量结果上报，能够提高定位精度。

本公开实施例中，网络设备确定了第二载波组后，可以进一步确定是否在第二载波组上进行定位用途参考信号的传输。
本公开实施例中，确定是否在第二载波组上进行定位用途参考信号传输的条件包括用于确定传输定位用途参考信号的条件或包括用于不传输定位用途参考信号的条件，基于该条件确定是否在第二载波组上进行定位用途参考信号传输。
