对上行定位进行介绍:
5G NR引入了多种定位技术,用于实现对终端的定位。对于上行定位技术和上下行混合定位技术,需要使用终端向网络设备发送的上行定位参考信号,来实现对终端的定位。上行定位参考信号是一种探测参考信号(Sounding Reference Signal,SRS),网络设备需要首先为终端配置上行定位参考信号,才能够接收到终端发送的上行定位参考信号。网络设备通过向终端发送上行定位参考信号配置,能够实现为终端配置上行定位参考信号。该上行定位参考信号配置包括终端发送上行定位参考信号时使用的时频资源。
在R16(Release 16)的NR中,引入了下述基于SRS进行终端定位的方法:
·增强小区身份标识(Identity Document,ID)定位法;
·上行链路到达时差定位法;
·多小区往返行程时间定位法;
·上行链路到达角定位法。
在上述方法中,需要使用上行定位参考信号。在R16中,通过上述方法对终端进行定位时,需要终端处于无线资源控制(Radio Resource Control,RRC)连接(connected)态,会导致终端的功耗开销较大。
在R17的NR中,支持了对RRC非激活(inactive)态的终端的定位。终端在处于RRC inactive态的情况下,可以向网络设备发送上行定位参考信号。具体的,网络设备在将终端从RRC connected态转换到RRC inactive态时,会通过RRC释放(release)消息为终端配置上行定位参考信号。上行定位参考信号对应的详细配置包含在RRC release消息的定位参考信号无线资源控制非激活态配置(srs-PosRRC-InactiveConfig)中。并且,在终端进行了小区重选的情况下,终端需要释放掉网络设备给其配置的上行定位参考信号,即释放掉上行定位参考信号配置。例如,终端在进行小区重选后,会删除本地保存的上行定位参考信号配置。
在R18的NR中,提出了低功耗高精度(Low Power High Accuracy,LPHA)定位的需求,即需要进一步降低终端定位的功耗,并且可能会引入对RRC空闲(idle)态终端的定位。对于给RRC idle态和RRC inactive态的终端配置上行定位参考信号的方式,如果沿用R17的机制,即通过RRC release消息配置,终端进行小区重选后上行定位参考信号配置失效。在这种配置方式下终端需要重新进入RRC connected来获取上行定位参考信号配置,这样会增加终端的功耗,无法满足LPHA的要求。
对终端的随机接入进行介绍:
终端的随机接入可分为2种类型,包括4步随机接入和2步随机接入。终端通过向基站发送消息1(Message 1,Msg 1),从而发起4步随机接入。终端通过向基站发送消息A(Message A,Msg A),从而发起2步随机接入。在4步随机接入中,终端在发送Msg 1后,会接收基站反馈的消息2(Message 2,Msg 2),之后终端会再向基站发送消息3(Message 1,Msg 3),以及接收基站反馈的消息4(Message 4,Msg 4),从而完成随机接入。在2步随机接入中,终端在发送Msg A后,会接收基站反馈的消息B(Message B,Msg B),从而完成随 机接入。其中,Msg A可视为将上行的Msg 1和Msg 3打包发送,Msg B可视为将下行的Msg 2和Msg 4打包发送。
本申请实施例提供的方法,通过为终端配置用于上行定位的随机接入信道(Random Access Channel,RACH)资源,从而实现对终端的上行定位。相较于现有方案中终端在小区重选后需要重新进入连接态来获取上行定位参考信号配置从而实现上行定位,本申请实施例提供的方法通过使用现有的随机接入机制来为进行终端的上行定位,能够避免终端在小区重选的情况下切换至连接态来进行上行定位,从而能够减少终端的功耗。本申请实施例提供的方法,还通过系统消息为终端配置上行定位参考信号,实现了通过使用系统消息的广播机制来为终端配置上行定位参考信号,从而进行终端的上行定位。同样能够避免终端在小区重选的情况下切换至连接态来进行上行定位,减少了终端的功耗。

可选地,该RACH资源配置携带在如下至少一种消息中:

·RRC消息。
可选地,网络设备通过广播的方式向终端发送SI,从而实现向终端发送RACH资源配置。示例地,该RRC消息为RRC release消息。
可选地,该RACH资源配置包括如下至少一种信息:

可选地,上述应答消息包括如下至少一种:

可选地,上述上行定位参考信号配置对应的定位参考信号配置标识,以及应答消息中携带的定位参考信号配置标识为随机接入前导码标识(Random Access Preamble Identifier,RAP ID)。
需要说明的是,若网络设备通过RRC消息(RRC release消息)给终端配置第一RACH资源,当终端通过Msg 1发送配置请求,并且网络设备向终端发送Msg 2后,终端的随机接入过程完成。原因在于网络设备通过RRC消息向终端配置的RACH资源是终端专用的,因此无需终端进行基于竞争的随机接入。
