具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
在本发明实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。本文中符号“/”表示关联对象是或者的关系,例如A/B表示A或者B。
在本发明的描述中,除非另有说明,“多个”的含义是指两个或两个以上。本发明提供的技术方案可以应用于各种通信系统,例如,5G通信系统,未来演进系统或者多种通信融合系统等等。可以包括多种应用场景,例如,机器对机器(machine to machine,M2M)、D2M、宏微通信、增强型移动互联网(enhance mobile broadband,eMBB)、超高可靠性与超低时延通信(ultra reliable&low latency communication,uRLLC)以及海量物联网通信(massive machine type communication,mMTC)等场景。例如:本发明实施例可以应用于5G通信系统的新空口(new radio,NR)定位技术中网络设备与终端设备之间的通信。
相关技术中,定位技术在生活中的应用随处可见,大家对于定位的延迟和准确性的要求也越来越严格。在许多定位应用中,精确定位通常是通过以下多种技术的组合来实现:
1)基于全球导航卫星系统(global navigation satellite system,GNSS)提供户外场景中的位置信息。
2)无线电技术,例如长期演进(long term evolution,LTE)网络,提供多种选项来定位用户、无线网络、地面信标系统等等)。
3)惯性测量单元(inertial measurement units,IMU)或传感器(例如,基于加速计追踪用户位置、陀螺仪、磁力仪或利用大气压力传感器进行垂直定位)。
上述这些技术都有望在未来实现准确定位方面发挥重要作用。
Rel-15 NR定位课题定义了Cell-ID以及基于轻量级表示协议(LTE Positioning Protocol,LPP)的独立于无线接入技术(RAT-independent)的定位方法。Rel-16主要研 究独立NR中基于无线接入技术(NR standalone RAT-dependent)的定位方法,具体包括:下行到达时间差(downlink-time difference of arrival,DL-TDOA)定位方法,下行发射倾角(Downlink Angle-of-Departure,DL-AoD)定位方法,上行到达时间差(uplink-time difference of arrival,UL-TDOA)定位方法,上行到达倾角(Uplink Angle of Arrival,UL-AoA),往返时延(Round-TripTime,RTT)定位方法以及增强型小区标识(enhanced cell-ID,E-CID)定位方法等。
定位技术使用的主要参考信号之一为用于定位的信道探测参考信号(SRS for positioning),以下简称为SRS。基于终端设备发送的SRS,网络可以测量到达时间、信号强度、到达倾角等,从而确定终端设备的位置信息。
SRS的配置信息都是由基站侧下发的,包括了SRS资源集类型、发送周期、每个SRS资源对应的空间关系配置信息,以及路损参考信号等配置信息,这些都可以通过RRC信令配置给UE。
相关技术中接收SRS的配置信息都是终端设备在连接态的行为,如果想要支持终端设备在空闲态/非激活态下发送SRS,那么如何发送SRS的配置信息以及保障SRS的配置信息的有效性都是需要解决的问题。
基于上述问题,本发明实施例提供一种发送SRS的信息配置方法,该方法终端设备可以接收网络设备发送的用于终端设备在非连接态发送SRS的配置信息,如此可以按照接收到的SRS的配置信息,在终端设备处于非连接态时发送SRS,从而可以支持终端设备在空闲态,或,非激活态下发送SRS。
本发明实施例提供的发送SRS的信息配置方法,可以应用于无线通信系统。示例性的,如图1所示,为本发明实施例提供的一种无线通信系统的系统架构示意图。在图1中,该无线通信系统包括终端设备和网络设备。在实际应用中上述终端设备与网络设备之间的连接可以为无线连接。在本发明实施例提供的发送SRS的信息配置方法应用在图1所示的无线通信系统之中时,网络设备可以向终端设备发送SRS的配置信息,该SRS的配置信息用于终端设备在非连接态发送SRS,在终端设备接收到发送SRS的配置信息之后,可以根据该发送SRS的配置信息,在终端设备处于非连接态(可以为空闲态,或,非激活态)时发送SRS,从而可以支持终端设备在空闲态,或,非激活态下发送SRS。
本发明实施例中的终端设备可以称之为用户设备(user equipment,UE)。该终端设备可以为个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备,该终端设备也可以为手机、移动台(mobile station,MS)、移动终端(mobile terminal)和笔记本电脑等,该终端设备可以经无线接入网(radio access network,RAN)与一个或多个核心网进行通信。例如,终端设备可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等,例如,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语音和/或数据。终端设备还可以为有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的网络中的终端设备等。上述仅仅是一种示例,实际应用中不限于此。
本发明实施例中的网络设备可以是LTE系统、NR通信系统,或者,授权辅助接入长期演进(authorized auxiliary access long-term evolution,LAA-LTE)系统中的演进型基站(evolutional node B,简称可以为eNB或e-NodeB)宏基站、微基站(也称为“小基站”)、微微基站、接入站点(access point,AP)、传输站点(transmission point,TP)或新一代基站(new generation Node B,gNodeB)等。上述网络设备还可以是未来 5G通信系统或未来演进网络中的其他类网络设备。
