具体实施方式
图1是本发明实施例的5G应用场景的示意图。
如图1所示,通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解,本发明实施例仅以5G通信系统100进行示例性说明,但本发明实施例不限定于此。也就是说,本发明实施例的技术方案可以应用于包括5G通信系统的各种场景。例如,5G通信系统和第一通信系统构成的混合部署场景等等。其中,该第一通信系统可以是任一种通信系统。例如:长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。
此外,本发明结合网络设备和终端设备描述了各个实施例。
其中,网络设备120可以指网络侧的任一种用来发送或接收信号的实体。例如,5G网络中的基站设备等。
终端设备110可以是任意终端设备。具体地,终端设备110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network)进行通信,也可称为接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。例如,可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant, PDA)、具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、可穿戴设备等。
但是,针对上述场景,如果第一通信系统下的主小区(PCell)不能工作在授权频段时(例如,LTE)。在5G NR中,PCell和辅助小区(SCell)都可以工作在非授权频段。基站在非授权频段上发送参考信号(例如,SSB和CSI-RS)时,可能遇到先听后说(LBT)失败而无法发送该参考信号,这种情况下,UE如何测量这些参考信号以及如何汇报给基站需要解决。
为了解决上述技术问题,本发明实施例中提供了一种用于测量的方法,通过网络设备为终端设备配置测量配置信息,得非授权频段上的5G终端设备能够对接收到的参考信号进行测量。
图2是本发明实施例的用于测量的示意性流程图。
具体而言,如图2所示,该方法包括:
210,网络设备向终端设备发送测量配置信息,该测量配置信息包括第一参考信号在非授权频段上的多个发送机会的配置信息。
220,该网络设备在该多个发送机会上,向该终端设备发送该第一参考信号。
230,该终端设备根据该多个发送机会上接收到的该第一参考信号的测量值,确定该小区质量。
简而言之,该网络设备向该终端设备发送测量配置信息,并根据该测量配置信息,向该终端设备发送该第一参考信号。
应理解,本发明实施例中的多个发送机会是网络设备为终端设备配置的可能的发送该第一参考信号的发送机会,本发明实施对网络设备具体在该多个发送机会上是否向该终端设备发送该第一参考信号不做具体限定。也就是说,该网络设备可以在该多个发送机会中的每个发送机会上向该终端设备发送该第一参考信号,也可以在该多个发送机会的部分发送机会上向该终端设备发送该第一参考信号,也可以在该多个发送机会不向该终端设备发送该第一参考信号。具体地,可以根据该第一参考信号的发送方式确定是否进行发送,也可以信道的空闲情况确定是否发送,本发明实施例不做具体限定。
换句话说,终端设备接收网络设备发送的测量配置信息;该终端设备根据该配置信息,在该多个发送机会上接收该第一参考信号并进行测量;该终端设备根据该多个发送机会上接收到的该第一参考信号的测量值,确定该小 区质量。
更具体地,该终端设备可以按照以下公式,确定该小区质量:
F n=(1-a)*F n-1+aM n
其中,该n表示采样的次数,该F n表示小区质量,该M n表示测量值,该a表示加权系数。
由于网络设备可能在该多个发送机会上的部分或者全部的发送机会上不向该终端设备发送该第一参考信号,因此很有可能导致该终端设备无法测量到某个参考信号,因此,小区质量的推算也需要考虑到由于参考信号缺失而导致某些采样值的缺失。
本发明实施例中,当采用值缺失时,采用上述公式计算小区质量时,采样次数不加1,即,跳过缺失的采样值。例如,该终端设备在该多个发送机会中的第一发送机会上,未接收到该第一参考信号时,可以将第二发送机会上接收到的该第一参考信号的测量值,确定为该第一发送机会上该第一参考信号的测量值,该第二发送机会在该第一发送机会之前。
即,本发明实施例中,终端设备在确定小区质量时,通过考虑采样值缺失的情况,能够有效提高该小区质量的准确度。
应理解,本发明实施例对测量配置信息的具体体现形式不做限定,下面进行示例性说明。
在一个实施例中,如图3所示,该测量配置信息可以直接为该终端设备配置该第一参考信号的多个发送机会,即该终端设备可以在该多个发送机会上等待接收该第一参考信号。
例如,该测量配置信息可以包括固定时间位置的多个偏移值。也就是说,该网络设备在根据该多个偏移值确定的该多个发送机会上,向该终端设备发送该第一参考信号。相应的,该终端设备只需要在根据该多个偏移值确定的该多个发送机会上,接收该网络设备发送的该第一参考信号。
在另一个实施例中,如图4所示,该多个发送机会可以属于同一个时间窗,该配置信息包括该多个发送机会在时间窗内的配置信息。也就是说,该网络设备在该同一个时间窗内的该多个发送机会上,通过先听后说的方式,向该终端设备发送该第一参考信号。相应的,该终端设备就需要在这个时间窗内接收网络设备可能发送的该第一参考信号。
本发明实施例中,先听后说(Listen Before Talk,LBT)可以理解为: 要传输数据的站点首先对媒体上有无载波进行监听,以确定是否有别的站点在传输数据。如果媒体空闲,该站点便可传输数据;否则,该站点将避让一段时间后再做尝试。
可选地,该网络设备向终端设备发送测量配置信息之前,该网络设备可以向该终端设备发送映射关系信息,该映射关系信息包括至少一个参考信号类型和上述至少一个参考信号类型对应的时间窗的信息,上述至少一个参考信号类型包括该第一参考信号的类型。换句话说,该终端设备可以在接收该测量配置信息之前,接收该网络设备发送的映射关系信息,该终端设备根据该映射关系信息和该第一参考信号的类型,确定该第一参考信号对应的时间窗;该终端设备根据该配置信息,在该第一参考信号对应的时间窗内的该多个发送机会上,接收该第一参考信号并进行测量。
进一步地,该时间窗的信息包括该时间窗的开始位置和/或该时间窗的结束位置。
应理解,本发明实施例中,对于该网络设备向终端设备发送测量配置信息方式不做具体限定。
例如,该网络设备可以向该终端设备发送系统信息,该系统信息包括该测量配置信息。
又例如,该网络设备可以向该终端设备发送无线资源控制(Radio Resource Control,RRC)信令,该RRC信令包括该测量配置信息。
还应理解,本发明实施例对第一参考信号的类型不做具体限定,例如,该第一参考信号为同步信息块(Synchronization Signal Block,SSB)或信道状态信息测量参考信号(Channel State Information Reference Signal,CSI-RS)。
进一步地,本发明实施例中,还提供了一种终端设备上报小区质量的方法。具体地,该终端设备向该网络设备发送上报信息,该上报信息包括指示信息和该终端设备基于该第一参考信号获取的小区质量,该指示信息用于指示该终端设备上报的小区质量为该终端设备考虑采样值缺失后的小区质量。针对网络设备来说,该网络设备接收该终端设备发送的上报信息,并基于该上报信息确定该终端设备上报的小区质量为该终端设备考虑采样值缺失后的小区质量。
图5是本发明实施例的网络设备的示意性框图。应理解,本发明实施例 的网络设备可应用于5G通信系统,即5G网络设备或者5G网元。
