步骤201,发送第一信令至目标小区;其中,
所述第一信令用于激活或去激活所述终端的目标小区发送定位相关信号;所述目标小区包括所述终端的服务小区和/或邻小区。
这样,终端就能够按照步骤202,通过发送第一信令至目标小区,即该终端的服务小区和/或邻小区,来直接激活或去激活目标小区发送定位相关信号,以便减少定位的时延,满足了对定位参考信号获取的及时性要求。
因此,应用本申请实施例的方法的终端,对于具有定位需求的场景,将 第一信令发送至该终端的服务小区和/或邻小区,即可激活服务小区和/或邻小区发送定位相关信号,以及时获取到定位参考信号;而不需要定位的场景,将第一第一信令发送至该终端的服务小区和/或邻小区,即可去激活服务小区和/或邻小区发送定位相关信号,避免信令资源的消耗。
应该知道的是,目标小区是网络侧设备(如基站,传输参考点(Transmission Reference Point,TRP),参考点(Reference Point,RP),射频头等)的小区。
可选地,该实施例中,所述定位相关信号包括以下至少一项:

b1)根据当前PRACH序列中的RO(PRACH Occasion)资源确定对应的定位参考信号(如,非周期或按需的PRS);
c1)根据RO资源携带的上行信息确定对应的定位参考信号(如,非周期或按需的PRS)。
这里,若根据a1)和b1)联合确定对应的定位参考信号(如,非周期或按需的PRS),如:根据a1)确定了第一定位参考信号(如,非周期或按需的PRS)的索引,根据b1)确定了定位参考信号(如,非周期或按需的PRS)的目标发送时机,则目标小区可在目标发送时机进行第一PRS的发送。
在上述确定发送的定位参考信号的示例3中,可执行以下至少之一:
a2)当前PRACH序列中约定特定的前导(preamble)序列(如根据特定根序列生成的,或者第几个preamble(即64个preamble的哪几个preamble))用于激活定位参考信号(如,非周期或按需的PRS)的发送;
b2)当前PRACH序列中的约定特定的资源(如预定的、发送目标随机接入前导序列随机接入时机RO资源)用于激活定位参考信号(如,非周期或按需的PRS)的发送,其中预定的RO资源为网络侧发送的配置信息中动态配置的,或预定义的;
c2)根据RO资源携带的上行信息确定对应的定位参考信号(如,非周期或按需的PRS)。
这里,若根据a2)和b2)联合确定对应的定位参考信号(如,非周期或按需的PRS),如:根据a2)确定了第二定位参考信号(如,非周期或按需的PRS)的索引,根据b2)确定了定位参考信号(如,非周期或按需的PRS)的目标发送时机,则目标小区可在目标发送时机进行第二定位参考信号(如,非周期或按需的PRS)的发送。
而上述的第一定位参考信号或第二定位参考信号的目标发送时机,都可以根据激活时间T1和时间偏移T2确定,如目标发送时机(发送时间)为T1+T2。这里,T2可以是基于终端能力配置的、基于网络侧能力配置的或者预定义的固定值;还可以是变量,如根据第一信令(如资源、根序列等)的配置而变化。该实施例中,发送时机不仅限于发送时间,还包括发送次数、发送周期等。

如此,第一信令可使用特定的无线消息管理(Radio Information Management,RIM)信号。其中,若目标信号的发送资源的时域位置固定,该时域位置可以是时分复用(Time Division Duplexing,TDD)的边界slot。而候选资源是针对终端的被调度资源。而第三预设条件和第四预设条件均为Comb与频域偏移一致,当然,第三预设条件和第四预设条件也可以是其它设置。
具体的,对于祖冲之(Zadoff-Chu,ZC)序列的目标信号,ZC循环移位表示是否激活,或者激活哪种定位相关信号。

这里,第二信令可以是服务小区发送至邻小区,或者服务小区发送至位置管理设备如LMF。而且,第二信令用于激活或去激终端接收定位参考信号,也可以是服务小区发送至终端的。因此,第二信令的实现,包括但不限于信号特征满足第一预设条件的目标信号,Xn接口信息,DCI,目标下行资源,LPPa或NRPPa信息中的至少一者。当然,LMF也可发送信令于激活或去激终端接收定位参考信号。
其中,可作为第二信令的目标信号可以与上述作为第一信令的目标信号相同,即第一预设条件与第二预设条件相同,如此,上述对作为第一信令的目标信号的限定,也适用于作为第二信令的目标信号。但是,对于作为第二信令的目标信号,若该目标信号和定位相关信号存在对应关系,其配置信息和定位相关信号存在对应关系,其发送资源和定位相关信号存在对应关系,或者其它有关定位相关信号的限定,此时,该定位相关信号为定位参考信号。而对于作为第二信令的目标信号,候选资源是针对邻小区被调度的资源。
此外,作为第二信令的信号特征满足第一预设条件的目标信号,还可以包括但不限于:较大时延、较大路损、区别于当前被终端测量的信号、携带发送小区的识别信息、预设时间内可检测的第二信令数目中的至少一项。其中,考虑邻小区的距离,目标信号需要较大时延,如连续2个符号发送、采用扩展循环前缀(Cyclic Prefix,CP)或者采用较小的子载波间隔。而连续2个符号发送,可以是聚合两个符号的CP到第一个符号,还可以是符号之间相位连续。考虑邻小区的距离,目标信号需要较大路损。目标信号区别于当前被终端测量的信号,可根据信号配置、序列设计。而目标信号携带发送小区的识别信息,可以是一个组(group)的识别信息(如group ID),即一定区域内的第二信令携带group ID都相同,这里,group ID可以由LMF指示或者预定义通过area ID或areascop约束。进一步的,一个服务小区也可以有i个组ID,i可选为1、2、4、8、16,上限可选的为128、256、1024、4096、65536。目标信号携带发送小区的识别信息包括:时分,即时域区分;频分,即不同频域位置区分不同小区;码分,即不同的RS序列。

这里,第一目标上行资源可单独作为第一信令;也可与第一信令的信号配套特定的上行资源,传输第一信令的信号和/或定位相关信号的配置信息。而由于第一目标上行资源携带的信息可被物理层解析,可选的,结合第一目标上行资源携带的信息和接收小区标识(或者预配置的定位参考信号的信息),确定需要发送的定位参考信号,当然,还可确定X和Y的取值。
如图3所示,第一信令包括信号序列301和携带定位相关信号的配置信息的第一目标上行资源302,激活目标小区在X+Y*14个符号之后发送定位相关信号303。第一信令与定位相关信号之间的时间可以使用符号为单位,也可使用时隙,或者其它。

若第一信令如SSB(除了主同步信号(Primary Synchronization Signal,PSS)和辅同步信号(Secondary Synchronization Signal,SSS),还携带物理广播信道(Physical Broadcast Channel,PBCH)信息),则该第一信令可使用至少一个符号用于激活或去激活发送定位相关信号,和/或,携带激活或去激活的指示信息(如识别标识、1bit信息)。该第一信令中,存在N5个符号发送信号,N6个符号携带配置信息。该配置信息可为与识别标识或者其他安全标识进行密钥保护或者加扰的信息。
该实施例中,激活或去激活发送定位相关信号的识别标识或安全密钥,可以是网络侧设备,或位置管理设备如LMF配置的。邻小区可以从网络侧得到预配置,或者布网预配置,或者结合配置。
另外,在该实施例中,第一目标上行资源的实现,也适用于目标下行资源,在此不再赘述。
此外,可选地,所述方法还包括:
通过第二目标上行资源发送所述定位相关信号的配置信息。
这里,第二目标上行资源是专用发送定位相关信号的配置信息的资源。
该实施例中,第一信令的配置信息可以由网络侧设备或LMF配置。因此,可选地,所述方法还包括:

信令的类型;
信号的标识ID或组ID;

信号的发送次数;
信号的时频资源;
信号的数目;
信号的空间关系;
信号的功率信息;
发送或停止发送所述第一信令;与所述定位相关信号的对应关系。
这里,第一信令的类型如上述可知,可以包括PRACH信号,专用激活或去激活信号(如SRS、目标信号),或者其它上行信号(UCI、第一目标上行资源信号)。与定位相关信号的对应关系可以是:第一信令激活或去激活全部,第一信令分别对应特定的定位相关信号等。
当然,第二信令、PRACH信号、SRS、UCI、第一目标上行资源等对应的配置信息,可以类似于上述的第一信令,在此不再赘述。
需要注意的是,所述第一信令,第二信令可以结合第二目标上行资源和/或第一目标上行资源确定发送的定位相关信号,而第二信令还可以结合第二目标上行资源和/或目标下行资源确定发送的定位相关信号。
该实施例中,定位参考信号的发送时机与激活或去激活的信令(如第一信令、第二信令),激活或去激活的信令还可用于信息交换(如:成功激活)。
可选地,目标小区收到第一信令后,会针对第一信令进行反馈,因此,所述发送第一信令至目标小区之后,还包括:
接收所述目标小区的第一反馈信息;其中,所述第一反馈信息用于指示以下至少一项:
是否成功激活或去激活发送所述定位相关信号;
是否成功接收所述第一信令。
终端接收到的第一反馈信息,指示是否成功激活或去激活发送定位相关信号,和/或,是否成功接收第一信令。
其中,第一反馈信息可通过UU信令交互,如发送于随机接入反馈(Rach access response,RAR)中,通过RAR的一个或多个比特信息进行上述指示,该信息可使用上行链路授权UL grant,或者小区无线网络临时标识(Cell-Radio Network Temporary Identifier,C-RNTI)(全0或全1)等;又如第一反馈信息是随机接入前导码认证(Random Access Preamble Identifier,RAPID),为gNB 在检测preamble时所得到的preamble index,如果终端发现接收到的RAPID与自己发送preamble(若preamble为定位特定的,则认为成功激活on demand PRS)时使用的索引相同,则认为成功接收到对应的RAR,其对应的RAPID媒体接入控制(Medium Access Control,MAC)子头由三个字段(E/T/RAPID)组成。
第一反馈信息还可通过检测接收的定位相关信号,确定是否激活或去激活预计的定位相关信号。
然而,在上述实施例中可知,服务小区可发送第二信令至邻小区,则邻小区可向服务小区反馈信息,如X2信令交互,或者,发送信令给LMF,LMF收集所有相关邻小区的反馈信息,发送确认响应(Acknowledgement,ACK)的邻小区或者否定响应(Negative Acknowledgement,NACK)的邻小区给服务小区。此时,邻小区的反馈信息也指示是否成功激活或去激活发送定位参考信号,和/或,是否成功接收第二信令。且邻小区的反馈信息可实现如上述的第一反馈信息,在此不再赘述。
另外,接收第一信令和/或第二信令的小区,还可向LMF反馈:小区通过单独的信令交换,通知LMF该小区激活或去激活对应信号;小区在其他信令交互时,携带小区的反馈信息给LMF,通知LMF该小区激活或去激活对应信号。具体的,可以反馈激活或去激活的信号ID、激活或去激活的源设备等。
该实施例中,可选地,所述目标小区是通过以下至少一种方式确定的:
网络侧配置;
所述终端监听的结果;
无线资源管理(Radio Resource Management,RRM)测量结果。
此外,对于目标小区,除通过终端的第一信令激活或去激活该目标小区发送定位相关信号之外,还可以通过LMF的第三信令激活或去激活该目标小区发送定位相关信号。故,目标小区接收到LMF的第三信令,会激活或去激活发送定位相关信号。
与第一信令相同的,在目标小区为服务小区和邻小区,或者目标小区为邻小区的情况下,第三信令用于激活或去激活目标小区发送定位参考信号;在目标小区为服务小区的情况下,第三信令用于激活或去激活目标小区发送 第二信令和定位参考信号。
而且,目标小区会接收LMF发送的所述第三信令的配置信息;或者,发送第三信令的配置信息,发送至LMF。该第三信令的配置信息包括以下至少一项:
信令的类型;
信号的标识ID或组ID;

信号的发送周期;
信号的发送次数;
信号的时频资源;
信号的数目;
信号的空间关系;
信号的功率信息;
发送或停止发送所述第三信令;
与所述定位相关信号的对应关系。
如此,第三信令的配置信息类似于第一信令的配置信息,在此不再赘述。
可选地,所述第三信令包括:
NRPPa信息。
而对于接收到第三信令的小区,也可向LMF进行信息反馈,小区通过单独的信令交换,通知LMF该小区激活或去激活对应信号;小区在其他信令交互时,携带小区的反馈信息给LMF,通知LMF该小区激活或去激活对应信号。具体的,可以反馈激活或去激活的信号ID、激活或去激活的源设备等。
该实施例中,终端将能够基于第一信令或第三信令激活服务小区发送的定位参考信号和邻小区发送的定位参考信号,进行定位测量,得到定位信息。
下面结合附图,说明本申请实施例方法在不同场景的应用(以激活PRS为例):
场景一、如图4所示,位置服务器(Location Based Services,LBS)向LMF发送位置请求,包括时延、精度阈值。这里,LMF配置PRS配置信息,向服务小区和邻小区发送PRS配置信息,用于后续PRS的发送。LMF也可 向终端发送PRS配置信息,用于后续终端测量PRS。终端发送PRS激活信令(即第一信令)至服务小区和邻小区,激活服务小区和邻小区发送PRS。如此,终端就能够测量服务小区和邻小区的PRS,完成定位。
其中,服务小区和邻小区还能够在接收到PRS激活信令后,向终端发送反馈信息,指示激活情况等信息。

其中,服务小区还能够发送PRS测量激活信令至终端,通知终端及时进行PRS测量。服务小区还能够发送PRS激活信令的配置信息,以便邻小区进行PRS激活信令的接收。邻小区还能够在接收到PRS激活信令后,向服务小区发送反馈信息,指示激活情况等信息。

此外,服务小区可向LMF发送LMF激活信令的同时,向邻小区发送PRS激活信令,激活邻小区发送PRS。
在上述场景中,配置信息可由两端设备交互配置,如PRS配置信息可以由服务小区配置,发送给LMF。
