具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
图1示出了本公开一个示意性实施例提供的通信系统的框图,该通信系统可以包括:核心网11、接入网12和终端13。
核心网11中包括若干个核心网设备110。核心网设备110包括接入和移动管理功能(Access and Mobility Management Function,AMF),会话管理功能(Session Management Function,SMF)以及用户面管理功能(User Plane Function,UPF)等设备,可选地,核心网11中还包括位置管理功能(Location Management Function,LMF)。其中,AMF用于控制终端的接入权限以及切换 等功能;SMF用于提供服务器连续性、服务器的不间断用户体验,如:IP地址和锚点变化等;LMF用于支持定位计算,从终端获取下行定位测量结果或定位估计。
接入网12中包括若干个接入网设备120。接入网设备120可以是基站,基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在长期演进(Long Term Evolution,LTE)系统中,称为eNodeB或者eNB;在5G新空口(New Radio,NR)系统中,称为gNode B或者gNB。随着通信技术的演进,“基站”这一名称可能描述,会变化。为方便本公开实施例中,上述为终端提供无线通信功能的装置统称为接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备、物联网(Internet of Things,IoT)设备、工业物联网(Industry Internet of Things,IIoT)设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端设备。接入网设备120与终端设备13之间通过某种空口技术互相通信,例如Uu接口。
本公开实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long Term Evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着 通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to Everything,V2X)系统等。本公开实施例也可以应用于这些通信系统。
NR Rel-16系统中新定义了下行定位参考信号PRS,支持周期性发送的PRS,而且在一个周期内可以支持PRS resource的重复发送,进一步会配置在周期内的重复发送次数以及每两个发送之间的时间间隔,而时间间隔为N个slot,其中N为自然数。目前PRS在一个slot内只能发送一次,而PRS占用的符号数可以是slot内连续的2、4、6、12个符号。起始符号位置可以是slot内第1~13个符号中的任意一个符号。
但是周期性发送时,存在不需要但依旧发送而导致信令浪费的问题;或,发送周期太大,使得定位时延大精度不够高的问题。
本公开实施例提供了一种基于需求(on-demand)的定位参考信号的传输方法,使定位参考信号根据实际定位需求进行发送,提高资源使用效率,减少定位时延,提高定位精度。同时也提供一种基于需求的定位测量结果的发送方法。

值得注意的是,上述内容中,以定位请求用于指示网络设备向终端设备发送定位参考信号的资源配置参数和/或定位参考信号为例进行说明。在一些实施例中,定位请求用于指示终端向网络设备发送测量结果。
步骤404,终端设备根据定位请求向网络设备发送定位测量结果。
也即,终端已针对下行定位参考信号进行测量,得到测量结果,发送定位 请求用于请求向网络设备发送测量结果。
响应于定位请求用于指示终端向网络设备发送定位测量结果,根据定位请求接收终端设备发送的定位测量结果。
可选地,当定位请求用于指示发送定位测量结果时,定位请求通过随机接入信道发送,从而测量结果通过四步随机接入信道4-step RACH中的消息Msg3或两步随机接入信道2-step RACH中的消息Msg A中的PUSCH发送。
在一些实施例中,定位请求也可以通过SR发送,测量结果通过接入网设备收到SR后向终端设备发送的DCI信令调度指示的PUSCH发送。
可选地,定位请求为网络设备向终端设备发送的请求。示意性的,接入网设备向终端设备发送寻呼消息,该寻呼消息中包括定位请求。由于定位请求用于指示终端设备向网络设备发送定位测量结果,故,终端设备通过四步随机接入信道4-step RACH中的消息Msg3或通过两步随机接入信道2-step RACH中的消息Msg A中的PUSCH资源向接入网设备发送定位测量结果。
综上所述,本实施例提供的参考信号的传输方法,通过定位请求指示定位参考信号的传输,也即,在确定定位请求后,根据定位请求确定资源配置参数后,传输定位参考信号,从而避免定位参考信号的多余传输而导致信令,以及避免定位参考信号传输周期较大而导致定位时延大精度不高的问题。另外,通过定位请求指示定位测量结果的传输,也即,在确定定位请求后,传输定位测量结果,从而提供一种非周期性的定位测量结果的发送方法。
