Description

一种非周期定位参考信号的测量上报方法和装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种非周期定位参考信号的测量上报方法和装置。
背景技术
在3GPP标准中，支持下行到达时间差(down link-time of arrival，DL-TDOA)、下行离开角(down link-angle of departure，DL-AOD)、上行到达时间差(up link-time of arrival，UL-TDOA)、上行到达角(up link-angle of arrival，UL-AOA)、多用户往返时延(multi-round trip time，multi-RTT)等多种定位技术。其中DL-TDOA、UL-TDOA以及multi-RTT算法是基于到达时间的定位技术，即需要接收端来测量发送端发送的信号的到达时间，进而换算成二者之间的距离信息，最后得到待定位目标的位置。DL-AOD和UL-AOA是基于角度的定位技术，即接收端测量发送端发送的参考信号的到达角度，然后根据接收方与已知位置的多个发送端的角度信息来推断接收方的位置。
实现定位功能的前提是收发双方需要协调来测量定位参考信号(positioning reference signal，PRS)，并根据PRS的测量结果进行后续的定位计算。在NR Rel-16协议版本中，只支持周期性的PRS发送，即一旦开启定位功能，网络设备会按照配置的周期，持续的发送PRS，这会带来以下两方面的问题：
第一方面，在发送PRS的符号上不能收发数据，造成数据吞吐率下降，对于用户设备(user equipment，UE)而言，UE需要接收来自多个网络设备的PRS，资源开销太大，甚至会中断数据的接收。另一方面，UE需要按照特定的周期来接收PRS，如果周期太大，会使得整个定位的时延增加，而如果周期太小，又增加了定位的资源开销。
发明内容
本申请实施例提供了一种非周期PRS的测量上报方法和装置，用来减少定位时延和减少定位资源开销。
第一方面，提供了非周期PRS的测量上报方法。该方法可以由终端设备执行，或者类似终端设备功能的芯片执行。该方法中，终端设备可以接收非周期PRS配置信息。终端设备还可以接收来自网络设备的第一值。其中，该第一值可以用于指示终端设备的n个非周期PRS的上报配置信息。一个非周期PRS的上报配置信息可以包括m个非周期PRS上报时间信息。n和m是大于0的整数。终端设备可以基于非周期PRS配置信息，接收非周期PRS。终端设备可以基于接收的非周期PRS和n*m个非周期PRS上报时间信息中的一个，上报非周期PRS的测量报告。
基于上述方案，网络设备可以触发终端设备进行非周期PRS的测量以及上报，并且网络设备可以向终端设备指示n*m个非周期PRS上报时间信息。因此，终端设备可以在n*m个非周期PRS上报时间信息中的一个，确定非周期PRS的上报时间，并在非周期PRS的上报时间上报非周期PRS的测量报告。由于上述PRS是非周期的PRS，因此可以减少定位资源开销，在有定位需求时可以通过非周期PRS实现的对终端设备的定位。
在一种可能的实现方式中，终端设备可以接收来自网络设备的第二值。终端设备可以基于第二值，从n*m个非周期PRS上报时间信息中确定一个非周期PRS上报时间信息；一个非周期PRS上报时间信息可以用于确定上报非周期PRS的测量报告的发送时间。
基于上述方案，终端设备可以通过来自网络设备的第二值，确定一个非周期PRS上报时间信息，继而确定非周期PRS的测量报告的发送时间，使得非周期PRS的测量报告的发送时间符合网络设备的调度。
在一种可能的实现方式中，第二值可以用于指示终端设备的通信数据的传输时间信息。可选的，上述通信数据可以不包含非周期PRS的测量报告以及非周期CSI。
基于上述方案，终端设备可以根据通信数据的传输时间信息，确定一个非周期PRS上报时间信息，可以降低非周期PRS的测量报告与通信数据发生冲突的可能性。
在一种可能的实现方式中，在n等于1时，终端设备可以在m个非周期PRS上报时间信息中，选择第二值指示的一个非周期PRS上报时间信息。或者，在n大于1时，终端设备可以从每一个非周期PRS的上报配置信息中，选择第二值指示的非周期PRS上报时间信息，终端设备可以从n个非周期PRS上报时间信息中，选择一个非周期PRS上报时间信息。
基于上述方案，终端设备可以基于网络设备指示的第二值，确定一个非周期PRS上报时间信息，可以降低非周期PRS的测量报告与通信数据发生冲突的可能性。

下面结合附图对本申请实施例提供的方法进行说明。
在最新的3GPP标准中，支持DL-TDOA、DL-AOD、UL-TDOA、UL-AOA、multi-RTT等多种定位技术。下面以DL-TDOA技术为例简单介绍定位的流程，参阅图1可以包括以下步骤：
S1、LMF向网络设备请求PRS的配置信息。
S2、网络设备将PRS的配置信息发送给LMF。
S3、LMF向UE指示PRS的配置信息。
S4、UE在接收到LMF的指示后，接收网络设备发送的PRS。
S5、UE对接收到的PRS进行测量。
例如测量PRS的TDOA、AOA和AOD等。
S6、UE将PRS的测量结果上报给LMF。
S7、LMF根据PRS的测量结果进行处理，得到UE的位置信息。
参阅图2，介绍一下基于TDOA的定位技术如何对测量结果进行处理得到待定位目标的位置。TDOA定位技术是通过计算双曲线的交点来估计目标的位置。如图2所示，假设3个基站的位置是已知的，这里定义第i个基站的坐标为(x i,y i)，待定位目标的坐标为(x UE,y UE)。假设把第1个基站作为参考基站，UE分别测量其他基站的PRS与参考基站的PRS之间的到达时间差Δt i1。根据双曲线的定义，双曲线上的两个固定的点的距离为PRS的到达时间差，UE位于以两个基站为焦点的双曲线上，则可以列出以下方程组：
Figure PCTCN2021083087-appb-000001
Figure PCTCN2021083087-appb-000002
上述两个方程中，c为光速，因为只有两个未知数(x UE,y UE)，联合方程(1)和(2)就可以得到(x UE,y UE)，即UE的位置坐标。
从上述定位流程及定位方法中可以发现，实现定位功能的前提是收发双方需要协调来测量PRS，并基于得到相关测量结果进行后续的定位计算。在NR Rel-16协议版本中，只支持周期性的PRS发送，即一旦开启定位功能，基站会按照配置的周期，持续的发送PRS，这会带来以下两方面的问题：第一方面，UE在发送PRS的符号上不能收发数据，造成数据吞吐率下降，对UE而言，UE需要接收来自多个网络设备的PRS，资源开销太大，甚至 会中断数据的接收。另一方面，UE需要按照特定的周期来接收PRS，如果周期太大，会使得整个定位的时延增加，而如果周期太小，又增加了定位的资源开销，如图3A所示。
基于上述问题，本申请实施例提供了一种非周期PRS的测量上报方法。该方法中，网络设备在某一个时刻发送非周期PRS，终端设备在相应的接收时间测量非周期PRS，并将测量结果进行上报。位置管理功能网元(location management function，LMF)可以基于终端设备上报的测量结果，处理得到终端设备的位置信息。
以下，介绍本申请实施例涉及的数据传输时间和非周期信道状态信息参考信号(channel state information reference signal，CSI-RS)上报时间。首先，基站会向UE发送下行控制信息(down link control information，DCI)，该DCI中会包含一个指示字段，CSI请求(CSI request)。该字段会指示一种非周期CSI触发状态，而每一种非周期CSI触发状态会关联一个或多个非周期CSI的上报配置。其中，一个非周期CSI的上报配置里面会包含一个CSI上报时间参数列表，该参数列表中的数值代表的是上报CSI的时隙偏置。而UE具体适用哪一个非周期CSI的上报配置，以及哪一个上报CSI的时隙偏置，由DCI指示。此外，一个非周期CSI上报配置里面还会关联一些CSI-RS的资源配置，即UE需要测量哪些CSI-RS资源后进行上报，或者说UE上报的测量结果是根据哪些CSI-RS测量得到的。
此外，DCI中还会携带一个字段，时域资源分配(Time domain resource assignment)，该字段的作用是指示物理上行共享信道(physical uplink shared channel，PUSCH)所在的时域位置，以及占用的时域符号个数。这里假设PUSCH所在时隙为Ks，DCI调度的PUSCH与DCI的时隙间隔为k2，非周期CSI上报的时隙偏置为Y，则DCI、PUSCH和非周期CSI上报所在时隙的时序关系如图3B所示。
具体的，如果一个DCI中同时出现了时域资源分配字段和CSI请求字段的时候，PUSCH所在的真正时隙是由这两个字段来共同决定的。在标准协议TS38.214-g30版本中有如下规定：
当UE收到一个DCI，该DCI指示的PUSCH只用来数据传输而没有调度非周期CSI上报，或者该PUSCH即被调度了数据传输又被指示了非周期CSI上报，此时PUSCH真正所在时隙由DCI中的时域分配字段来指示，即该字段会指示一个时隙偏置值K 2，PUSCH所在时隙为：K s＝n+K 2；
当UE收到一个DCI，该DCI指示的PUSCH只用来承载非周期CSI上报信息，而没有数据传输，此时PUSCH所在时隙并不是由时域分配字段决定，而是由CSI请求字段所指示的CSI上报时刻来决定：K 2＝max jY j(m+1)。
其中，m是由时域分配字段来指示，Y j是指DCI调度的一个非周期CSI上报配置中，第j个非周期CSI上报的时隙偏置，max j是指取Y j的最大值。之所以取最大值是因为一个DCI可能触发了多个非周期CSI的上报，这里以所有非周期上报里面的最大时隙偏置作为非周期CSI上报时隙偏置以及PUSCH所在的时隙偏置。这样做的好处是可以保证UE测量完所有非周期CSI-RS后都能来得及在PUSCH上报。
需要说明的是，非周期PRS与非周期CSI-RS有很大的区别。首先非周期PRS是由多个网络设备发给UE的，UE需要接收来自多个网络设备的PRS，并且对于每一个接收到的PRS，UE都需要进行相关检测来确定其到达时间以及接收功率，而这个过程会占用大量的芯片资源。首先对于定位来说，至少需要测量得到3个网络设备的PRS才能满足基本的定位功能，而不同网络设备发送的PRS到达UE的时间间隔也是不确定的。而且对于大部分UE，需要向网络设备请求测量间隔来进行PRS的测量，即在这个测量时间窗内UE只会接 收PRS，而不会接收其他数据或信号。
总之，UE在上报非周期PRS测量结果之前，需要保证足够的时间来接收并测量有效的PRS，才不会影响定位精度。

步骤501：终端设备接收PRS配置信息。
这里的PRS配置信息可以是正在为终端设备提供服务的网络设备发送给终端设备的，或者也可以是LMF发送给终端设备的。其中，LMF可以在接收到定位请求信息时，请求网络设备上报PRS配置信息。

步骤502：网络设备向终端设备发送第一值，相应的终端设备接收第一值。
其中，第一值可以用于指示终端设备的n个非周期PRS的上报配置信息。一个非周期PRS的上报配置信息可以包括m个非周期PRS的上报时间信息。这里的n和m均是大于0的整数。
步骤503：终端设备基于PRS配置信息，接收PRS。
其中，终端设备可以基于PRS配置信息，接收网络设备发送的PRS。终端设备可以根据多个PRS配置信息，分别接收多个网络设备发送的PRS。
在一个示例中，终端设备可以对接收到的PRS进行测量，得到测量结果。其中，测量结果可以是PRS的信号与干扰噪声比(signal to interference plus noise ratio，SINR)、参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)、相对到达时间(relative time of arrival，RTOA)或者到达角(angle of arrival，AOA)。可选的，测量结果也可以是上述多个测量量的量化结果。

以下，首先对第一值进行解释和说明。
上述第一值可以用于指示一个非周期触发状态，每一个非周期触发状态可以关联一个或多个非周期PRS上报配置信息。网络设备可以通过DCI向终端设备发送第一值。例如，在DCI format 0_1/0_2中添加一个新的字段“PRS请求(PRS request)”，用于指示一个非周期触发状态。以下，介绍承载上述第一值的信令一。该信令一中可以包含以下信息元素：
1、aperiodicPRSTriggerStateList，解释为非周期触发状态表。其中，aperiodicPRSTriggerStateList的取值(SEQUENC)定义为第一值，解释为上述非周期触发状态表中，第一值所指示的非周期触发状态。第一值的取值的范围可以是从1到非周期触发状态的取值的最大值(maxNrofPRS-TriggerStates)。
2、aperiodicPRSTriggerStateList，解释为上述第一值所指示的非周期触发状态。其中，aperiodicPRSTriggerStateList的取值(SEQUENC)用于一个或多个指示非周期PRS上报配置信息表(PRSReportConfigList)。上述PRS上报配置信息表可以包含一个或多个取值，每一个取值可以用于指示一个非周期PRS上报配置信息。其中，PRS上报配置信息的取值的范围可以是从1到非周期PRS上报配置信息的取值的最大值(maxNrofReportConfigPerAperiodicTrigger)。
需要说明的是，上述一个或多个非周期PRS上报配置信息表可以是网络设备在触发非周期PRS上报之前，配置给终端设备的。比如，网络设备可以通过高层信令，向终端设备指示一个或多个非周期PRS上报配置信息。以下，介绍承载非周期PRS上报配置信息的信令二。该信令二可以包括以下信息元素：
1、PRSReportConfig，解释为非周期PRS上报配置信息。其中，一个非周期PRS上报配置信息对应有一个取值。
2、reportSlotOffsetList，解释为非周期PRS上报时隙偏移表。该表中可以包含一个或多个取值，每一个取值可以指示一个非周期PRS上报时隙偏移。这里的非周期上报时隙偏移是指上报非周期PRS的测量报告的时隙与接收触发非周期PRS测量的信令之间的时隙偏移。可选的，非周期PRS上报时隙偏移表也可以是非周期PRS的测量报告的发送时间表，该表中每一个取值可以用于指示一个非周期PRS的测量报告的发送时间。
可选的，信令二还可以包含下行PRS资源集的标识、下行PRS资源的标识等。其中，下行PRS资源集的标识用于指示网络设备配置的下行PRS资源集，下行PRS资源的标识可以用于指示上述下行PRS资源集中终端设备可以接收的下行PRS资源。
在一种可能的实现方式中，网络设备可以通过上述信令一触发终端设备接收非周期PRS，并上报非周期PRS的测量报告。
以下，对终端设备上报非周期PRS的测量报告的时间进行说明。其中，终端设备可以根据第一值指示的n个非周期PRS的上报配置信息，以及每一个非周期PRS的上报配置信息包含的m个非周期PRS上报时间信息中，确定上报非周期PRS的测量报告的时间。其中，终端设备可以接收来自网络设备的第二值。上述第二值可以用于指示终端设备的通信数据的传输时间信息。例如，该第二值可以是前述DCI中时域资源分配字段的取值。终端设备可以根据所述第二值，从n*m个非周期PRS上报时间信息中确定一个非周期PRS上报时间信息。该非周期PRS上报时间信息可以是非周期PRS的测量报告的发送时间，或者也可以是非周期PRS的测量报告的发送时间与第一值的接收时间之间的时间差信息。终端设备可以基于确定的一个非周期PRS上报时间信息，确定非周期PRS的测量报告的发送时间。可选的，上述第二值也可以是网络设备指示的通信数据的发送时间。
在一种可能的实现方式中，在n等于1时，终端设备在第一值指示的一个非周期PRS的上报配置信息包含的m个非周期PRS上报时间信息中，确定第二值指示的一个非周期PRS上报时间信息。其中，可以将第二值的取值定义为j，第二值指示的一个非周期PRS 上报时间信息可以是第j个非周期PRS上报时间信息。举例来说，第一值指示的一个非周期PRS的上报配置信息包含的m个非周期PRS上报时间信息分别为(a1,a2,a3,a4,a5,a6)，第二值取值为3，则第二值指示的非周期PRS上报时间信息可以是a3。
另一种可能的实现方式中，在n大于1时，终端设备可以从n非周期PRS上报时间信息中，分别确定n个第二值指示的非周期PRS上报时间信息。终端设备可以从n个非周期PRS上报时间信息中，选择一个非周期PRS上报时间信息。可选的，终端设备可以从n个非周期PRS上报时间信息中，随机选择一个非周期PRS上报时间信息，或者终端设备可以从n个非周期PRS上报时间信息中选择一个取值最大的非周期PRS上报时间信息。举例来说，第一值指示了三个非周期PRS的上报配置信息，分别为A1、A2和A3。其中，A1包含的非周期PRS上报时间信息可以是(a1,a2,a3,a4,a5,a6)，A2包含的非周期PRS上报时间信息可以是(b1,b2,b3,b4,b5)，A3包含的非周期PRS上报时间信息可以是(c1,c2,c3,c4,c5,c6)。第二值的取值可以是4，则终端设备可以根据第二值确定三个非周期PRS上报时间信息，a4,b4和c4。其中，终端设备可以在a4,b4和c4中随机选择一个非周期PRS上报时间信息，并根据选择的一个非周期PRS上报时间信息确定非周期PRS的测量报告的发送时间。例如，终端设备可以选择a4，根据a4确定非周期PRS的测量报告的发送时间。或者，终端设备可以在a4,b4和c4中选择取值最大的非周期PRS上报时间信息，并根据取值最大的非周期PRS上报时间信息确定非周期PRS的测量报告的发送时间。例如，a4＜b4＜c4，则终端设备可以根据c4确定非周期PRS的测量报告的发送时间。
可选的，假设第二值取值为6，由于A2中包含5个非周期PRS上报时间信息，即不存在第6个非周期PRS上报时间信息，则终端设备可以在A1、A2和A3中确定两个非周期PRS上报时间信息，a6和c6。终端设备可以在a6和c6中选择一个非周期PRS上报时间信息，进而确定非周期PRS的测量报告的发送时间，或者终端设备可以在a6和c6中选择一个取值最大的非周期PRS上报时间信息，进而确定非周期PRS的测量报告的发送时间。
终端设备可以根据上述确定的一个非周期PRS上报时间信息确定非周期PRS的测量报告的发送时间。其中，终端设备确定非周期PRS的测量报告的发送时间的方法，可以包括以下两种方法。在以下实施例中，可以将确定的一个非周期PRS上报时间信息定义为P。
方法一、未触发终端设备进行非周期CSI上报。
其中，如果在预设时长内未触发终端设备进行非周期CSI上报，则可以根据终端设备的待传输通信数据的发送时间和上述确定的一个非周期PRS上报时间信息，确定非周期PRS的测量报告的发送时间。这里的预设时长可以是终端设备接收到上述第一值的时间至终端设备上报非周期PRS的测量报告的时间之间的时长。或者，如果承载上述第一值的信令未触发非周期CSI上报，则终端设备可以根据待传输通信数据的发送时间和上述确定的一个非周期PRS上报时间信息，确定非周期PRS的测量报告的发送时间。
在一个示例中，如果终端设备在第二值所指示的时间上有通信数据传输，则终端设备可以在确定的一个非周期PRS上报时间信息和第二值中，选择取值较大的一个值。终端设备可以基于选择的较大的一个值，发送非周期PRS的测量报告。
举例来说，参阅图6A，终端设备在时隙n接收来自网络设备的DCI，该DCI调度的PUSCH上有通信数据传输并且该DCI触发了非周期PRS上报。其中，上述DCI中指示了第二值K2。那么承载非周期PRS的测量报告的PUSCH发送时隙可以由n+max(K2,P)来决 定。假设K2＞P，则终端设备可以在时隙n+K2上发送承载非周期PRS的测量报告的PUSCH。
或者，承载非周期PRS的测量报告的发送时隙可以由max(K2,P)来决定。假设K2＞P，则终端设备可以在K2上发送承载非周期PRS的测量报告的PUSCH。可选的，该PUSCH中还可以承载终端设备的通信数据。
另一个示例中，如果终端设备在第二值所指示的时间上没有通信数据传输，则终端设备可以基于确定的一个非周期PRS上报时间信息，发送非周期PRS的测量报告。
举例来说，参阅图6B，终端设备在时隙n接收来自网络设备的DCI，该DCI调度的PUSCH上没有通信数据传输并且该DCI触发了非周期PRS上报。那么承载非周期PRS的测量报告的PUSCH传输时刻由n+P来决定。其中，终端设备可以在时隙n+P上发送承载非周期PRS的测量报告的PUSCH。
或者，承载非周期PRS的测量报告的发送时隙可以由P来决定。其中，终端设备可以在时隙P上发送承载非周期PRS的测量报告的PUSCH。
方法二、触发终端设备进行非周期CSI上报。
其中，如果在预设时长内触发终端设备进行非周期CSI上报，则终端设备可以根据上报非周期CSI的时间、待传输通信数据的发送时间和上述确定的一个非周期PRS上报时间信息，确定非周期PRS的测量报告的发送时间。预设时长可以参见上述方法一中的描述。或者，如果承载上述第一值的信令触发非周期CSI上报，则终端设备可以根据上报非周期CSI的时间、待传输通信数据的发送时间和上述确定的一个非周期PRS上报时间信息，确定非周期PRS的测量报告的发送时间。
需要说明的是，确定非周期CSI的上报时间的方法可以与本申请实施例中非周期PRS上报时间信息的方法相同。举例来说，网络设备可以为终端设备确定一个或多个非周期CSI的上报配置信息。每个非周期CSI的上报配置信息中可以包含k个非周期CSI的上报时间。其中，如果网络设备为终端设备确定一个非周期CSI的上报配置信息，终端设备可以根据第二值从k个非周期CSI的上报时间中选择相应的一个非周期CSI的上报时间。如果网络设备为终端设备确定y个非周期CSI的上报配置信息，终端设备可以从k*y个非周期CSI的上报时间中，选择y个第二值指示的非周期CSI的上报时间。终端设备可以从y个非周期CSI的上报时间中，选择一个最大的非周期CSI的上报时间。
在一个示例中，如果终端设备在第二值所指示的时间上有通信数据传输，则终端设备可以在第二值和第四值中确定一个较大的值。这里的第四值可以是第三值与确定的一个非周期PRS上报时间信息P指示的时间的和；第三值可以是上述CSI request字段中指示的上报非周期CSI的时隙与n的偏移，或者第三值可以是上述CSI request字段中指示的上报非周期CSI的时隙。终端设备可以根据第二值和第四值中一个较大的值，确定非周期PRS的测量报告的发送时间。
举例来说，参阅图7A，终端设备在时隙n接收来自网络设备的DCI，该DCI调度的PUSCH上有通信数据传输并且该DCI触发了非周期PRS上报以及非周期CSI上报。其中，上述DCI中指示了第二值K2。上述DCI中也指示了第三值Y。那么承载非周期PRS的测量报告的PUSCH的发送时隙可以由n+max(K2,Y+P)来决定。假设K2＜Y+P，则终端设备可以在时隙n+Y+P上发送承载非周期PRS的测量报告的PUSCH。
或者，承载非周期PRS的测量报告的PUSCH的发送时隙可以由max(K2,Y+P)来决定。假设K2＜Y+P，则终端设备可以在时隙Y+P上发送承载非周期PRS的测量报告的PUSCH。 可选的，上述PUSCH中还可以包含通信数据和/或非周期CSI。应理解，图7A中接收CSI-RS和接收PRS的时序是示例性的，并不限定于终端设备先接收CSI-RS再接收PRS，或者也不限定于终端设备先接收PRS再接收CSI-RS。
另一个示例中，如果终端设备在第二值所指示的时间上没有通信数据传输，则终端设备可以根据第五值确定非周期PRS的测量报告的发送时间。其中，第五值可以是上述确定的一个非周期PRS上报时间信息P与第三值Y的和。
举例来说，参阅图7B，终端设备在时隙n接收来自网络设备的DCI，该DCI调度的PUSCH上没有通信数据传输并且该DCI触发了非周期PRS上报以及非周期CSI上报。其中，上述DCI中指示了第二值K2。上述DCI中也指示了第三值Y。那么承载非周期PRS的测量报告的PUSCH的发送时隙可以由n+Y+P来决定。终端设备可以在时隙n+Y+P上发送承载非周期PRS的测量报告的PUSCH。
或者，承载非周期PRS的测量报告的PUSCH的发送时隙可以有Y+P来决定。终端设备可以在时隙Y+P上发送承载非周期PRS的测量报告的PUSCH。可选的，上述PUSCH中还可以包含通信数据和/或非周期CSI。应理解，图7B中接收CSI-RS和接收PRS的时序是示例性的，并不限定于终端设备先接收CSI-RS再接收PRS，或者也不限定于终端设备先接收PRS再接收CSI-RS。
基于上述方法一和方法二，在不同情况下终端设备的非周期PRS的测量报告的发送时间，可以如下表1所示。
表1
有无通信数据传输 有无非周期CSI上报 有无非周期PRS上报 PUSCH开始时隙
有 有 有 n+max(K2,P+Y)
有 无 有 n+max(K2,P)
无 无 有 n+P
无 有 有 n+Y+P
可选的，终端设备基于上述方法一和方法二确定的非周期PRS的测量报告的发送时间，可以是终端设备实际发送非周期PRS的测量报告的发送时间。或者，终端设备发送非周期PRS的测量报告的实际时间，与上述确定的发送时间之间可以设置一个时间偏移。例如，终端设备基于上述方法一和方法二确定非周期PRS的测量报告的发送时间为n+Y+P，终端设备发送非周期PRS的测量报告的实际时间可以是n+Y+P+offset。这里的offset为时间偏移的取值，时间偏移的取值可以是网络设备发送给终端设备的、或者可以是协议规定的，或者也可以是网络设备和终端设备协商的。
网络设备可以在上述非周期PRS的测量报告的发送时间，或者非周期PRS的测量报告的实际发送时间，接收来自终端设备的非周期PRS的测量报告。网络设备可以将非周期PRS的测量结果发送给LMF。LMF可以基于非周期PRS的测量结果，处理得到终端设备的位置信息。其中，LMF可以采用UL-AOA定位技术，或者UL-TDOA定位技术处理得到终端设备的位置信息。需要说明的是，LMF也可以采用其他的定位技术确定终端设备的位置信息，本申请不做具体限定。
基于上述方案，网络设备可以通过DCI触发终端设备进行非周期PRS上报。终端设备可以根据通信数据传输时间、非周期CSI上报时间和非周期PRS上报时间中的一个或多 个，确定非周期PRS的测量报告的发送时间。因此，在同时触发非周期CSI上报和非周期PRS上报时，终端设备可以有足够的时间接收和测量PRS，可以提高定位精度，提高了非周期PRS的定位性能。
在一种可能的实现方式中，终端设备可以向定位服务器和/或网络设备发送第一能力信息。这里的第一能力信息包括终端设备支持非周期PRS的定位。可选的，该第一能力信息也可以包括终端设备对PRS的处理能力和终端设备对PRS的测量能力等。
另一种可能的实现方式中，终端设备可以向定位服务器和/或网络设备发送第二能力信息。这里的第二能力信息可以用于指示终端设备支持非周期CSI上报和非周期PRS上报的同时触发，或者第二能力信息可以用于指示终端设备不支持非周期CSI上报和非周期PRS上报的同时触发。可选的，如果终端设备支持非周期CSI上报和非周期PRS上报，则网络设备可以通过一个DCI触发终端设备进行非周期PRS上报和非周期CSI上报。例如，触发终端设备进行非周期PRS上报的DCI中包含CSI request字段和第一值。如果终端设备不支持非周期CSI和非周期PRS同时触发，则网络设备在通过一个DCI触发终端设备进行非周期PRS上报时，该一个DCI不可以触发终端设备进行非周期CSI上报。例如，触发终端设备进行非周期PRS上报的DCI中不包含CSI request字段或者第三值。
在一个示例中，在终端设备不支持非周期CSI和非周期PRS同时触发时，非周期PRS的测量报告的发送时间可以由以下表2所示。
表2
有无通信数据传输 有无非周期CSI上报 有无非周期PRS上报 PUSCH开始时隙
有 无 有 n+max(K2,P)
无 无 有 n+P
以下，通过具体实施例对本申请提供的非周期PRS的测量上报方法进行说明。
实施例1、
参阅图8，为本申请实施例提供的非周期PRS的测量上报方法的示例性流程图，可以包括以下步骤：
步骤801、LMF接收定位请求消息。
这里的定位请求信息可以用于请求终端设备的位置信息。其中，该定位请求信息可以是终端设备发送的，或者也可以是想要获取终端设备的位置信息的第三方服务器发起的。该定位请求信息可以是位置服务请求(location service request)消息，或者也可以是新定义消息。
步骤802、LMF向终端设备发送定位能力请求消息。
这里的定位能力请求消息可以用于请求终端设备的定位能力信息。其中，LMF可以通过长期演进定位协议(long term evolution positioning protocol，LPP)消息向终端设备发送定位能力请求消息。该定位能力请求消息可以是LPP请求能力(request capabilities)消息，或者也可以是新定义消息。
步骤803、终端设备向LMF发送第一能力信息。
可选的，终端设备也可以向LMF发送第二能力信息。其中，第一能力信息和第二能力信息可以参见上述如图5所示的方法实施例中的相关描述，此处不再赘述。
步骤804、LMF向网络设备请求非周期PRS的配置信息。
其中，LMF可以向网络设备发送传输接收点(transmission and reception point，TRP)信息(information)请求(request)消息。该TRP information request消息可以用于请求网络设备上报非周期PRS的配置信息。可选的，LMF可以向终端设备发送该非周期PRS的配置信息。
步骤805、网络设备向LMF发送非周期PRS的配置信息。
其中，非周期PRS的配置信息可以参见如图5所示的方法实施例中的相关描述，此处不再赘述。可选的，LMF可以向终端设备发送该非周期PRS的配置信息，或者网络设备可以向终端设备发送该非周期PRS的配置信息。
步骤806、网络设备向终端设备发送DCI。
这里的DCI可以用于触发终端设备进行非周期PRS上报。该DCI中可以包含第一值。可选的，该DCI中还可以包含第二值和第三值。其中，该DCI可以参见如图5所示的方法实施例中信令一和信令二的相关描述，此处不再赘述。
步骤807：网络设备发送非周期PRS，相应的终端设备接收非周期PRS。
其中，多个网络设备可以广播非周期PRS，终端设备可以接收来自多个网络设备的非周期PRS。
步骤808、终端设备对接收到的非周期PRS进行测量。
其中，终端设备可以根据来自网络设备或者来自LMF的非周期PRS的配置信息，接收来自一个或多个网络设备的PRS，并对接收到的PRS进行测量。
步骤809、终端设备向网络设备发送非周期PRS的测量报告。
其中，终端设备可以在PUSCH上承载非周期PRS的测量报告。非周期PRS的测量报告的发送时间可以参见如图5所示的方法实施例中的相关描述，此处不再赘述。
步骤810、网络设备向LMF发送非周期PRS的测量结果。
步骤811、LMF根据非周期PRS的测量结果，处理得到终端设备的位置信息。
其中，LMF可以采用UL-AOA定位技术，或者UL-TDOA定位技术处理得到终端设备的位置信息。应理解，LMF还可以采用其他定位技术处理得到终端设备的位置信息，本申请不做具体限定。
本申请实施例给出了非周期PRS上报时的时序逻辑关系，使得终端设备和基站对于何时传输承载非周期PRS的测量报告的PUSCH有了统一的理解。例如，如果DCI只触发了非周期PRS的上报，此时承载非周期PRS的测量报告的PUSCH所在时隙可以由非周期PRS上报时间信息来决定，这样可以使得UE有足够时间来测量非周期PRS。而对于非周期CSI和非周期PRS上报同时触发的情景，终端设备不仅需要测量CSI-RS，还要测量PRS，而且二者还需要分时测量，所以需要给终端设备预留足够的时间来进行测量，所以上报时间需要以非周期CSI上报时间信息和非周期PRS上报时间信息来决定。这样既可以提高CSI-RS测量的完整性，又可以提高非周期PRS的定位精度。
基于与上述通信方法的同一技术构思，如图9所示，提供了一种装置900。装置900能够执行上述方法中由终端设备和网络设备侧执行的各个步骤，为了避免重复，此处不再详述。
