Description
本申请要求于2021年9月29日提交国家知识产权局、申请号为202111154644.2、申请名称为“参考信号处理方法、装置、终端及介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请属于通信技术领域,具体涉及一种参考信号处理方法、装置、终端及介质。
目前,在非授权通信***中,网络侧设备可以采用定向传输前侦听(Directional Listen Before Talk,Directional LBT),对非授权频谱的某个波束方向上的信道进行监听。在确定该信道空闲时,网络侧设备可以接入该信道,并在信道占用时间(Channel Occupancy Time,COT)内通过该信道向用户设备(User Equipment,UE)进行传输(例如传输参考信号),从而UE可以接收网络侧发送的参考信号进行无线链路监测(Radio Link Monitoring,RLM)。
但是,由于可能会出现在发送参考信号波束方向上的信道繁忙的情况,此时可能会出现网络侧设备在发送参考信号方向上的Directional LBT失败,参考信号无法发送,而UE此时仍在该波束方向上接收参考信号并进行RLM,因此,导致UE根据参考信号进行RLM的结果的准确性较差。
如此,导致UE的通信质量较差。
发明内容
本申请实施例提供一种参考信号处理方法、装置、终端及介质,能够解决UE的通信质量较差的问题。
第一方面,提供了一种参考信号处理方法,该方法包括:UE从网络侧设备接收目标指示信息;在第一空域范围和目标空域范围间满足预设条件的情况下,UE执行目标操作;其中,该第一空域范围是:根据第一信道的空域范围得到的,或根据空域指示信息得到的;该第一信道是:承载目标指示信息的信道;该空域指示信息为目标指示信息中包括的指示信息;该目标空域范围为:网络侧设备配置的参考信号的空域范围;该目标操作包括以下至少一项:从网络侧设备接收参考信号、测量参考信号。
第二方面,提供了一种参考信号处理装置,该参考信号处理装置包括:接收模块和执行模块。其中,接收模块,用于从网络侧设备接收目标指示信息。执行模块,用于在第一空域范围和目标空域范围间满足预设条件的情况下,执行目标操作。其中,该第一空域范围是:根据第一信道的空域范围得到的,或根据空域指示信息得到的;该第一信道是:承载目标指示信息的信道,该空域指示信息为目标指示信息中包括的指示信息;该目标空域范围为:网络侧设备配置的参考信号的空域范围;该目标操作包括以下至少一项:从网络侧设备接收参考信号、测量参考信号。
第三方面,提供了一种终端,该终端包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的程序或指令,所述程序或指令被所述处理器执行时实现如 第一方面所述的方法的步骤。
第四方面,提供了一种终端,包括处理器及通信接口,其中,该通信接口,用于从网络侧设备接收目标指示信息。该处理器,用于在第一空域范围和目标空域范围间满足预设条件的情况下,执行目标操作。其中,该第一空域范围是:根据第一信道的空域范围得到的,或根据空域指示信息得到的;该第一信道是:承载目标指示信息的信道,该空域指示信息为目标指示信息中包括的指示信息;该目标空域范围为:网络侧设备配置的参考信号的空域范围;该目标操作包括以下至少一项:从网络侧设备接收所述参考信号、测量参考信号。
第五方面,提供了一种可读存储介质,所述可读存储介质上存储程序或指令,所述程序或指令被处理器执行时实现如第一方面所述的方法的步骤。
第六方面,提供了一种芯片,所述芯片包括处理器和通信接口,所述通信接口和所述处理器耦合,所述处理器用于运行程序或指令,实现如第一方面所述的方法的步骤。
第七方面,提供了一种计算机程序/程序产品,所述计算机程序/程序产品被存储在非易失的存储介质中,所述程序/程序产品被至少一个处理器执行以实现如第一方面所述的方法的步骤。
在本申请实施例中,UE可以从网络侧设备接收目标指示信息,以根据承载该目标指示信息的第一信道的空域范围(或该目标指示信息中包括的空域指示信息)得到第一空域范围,再确定该第一空域范围和网络侧设备配置的参考信号的目标空域范围间是否满足预设条件,从而在确定该第一空域范围和目标空域范围间满足预设条件的情况下,UE可以从网络侧设备接收该参考信号,和/或测量该参考信号。由于UE可以先从网络侧设备接收目标指示信息,以得到网络侧设备要发送信号的第一空域范围,这样UE可以确定该要发送的信号的第一空域范围、与网络侧设备配置的网络侧设备通过某个波束方向上的信道发送的参考信号的目标空域范围间是否满足预设条件,以确定该要发送的信号的波束范围是否覆盖通过某个波束方向上信道发送的参考信号的波束范围,并在确定该要发送的信号的波束范围覆盖通过某个波束方向上的信道发送的参考信号的波束范围的情况下,UE可以从网络侧设备接收该参考信号,和/或测量该参考信号,以进行RLM,因此,可以避免在网络侧设备在发送参考信号的波束方向上的Directional LBT失败,参考信号无法发送的情况下,UE仍在该波束方向上接收参考信号并进行RLM的问题,从而可以提升UE根据参考信号进行RLM的结果的准确性,如此,可以提升UE的通信质量。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。
1、非授权通信***
非授权频段(Unlicensed Band)可以作为授权频段(Licensed Band)的补充帮助运营商对服务进行扩容。由于非授权频段由多种技术(Radio Access Technology,RAT)共用,例如无线保真(Wireless Fidelity,Wi-Fi)、雷达、基于LTE的授权频谱辅助接入到非授权频谱(LTE-based Licensed-Assisted Access,LTE-LAA)等,因此在某些国家或者区域,非授权频段在使用时必须符合监管条例以保证所有通信设备可以公平地共享该资源,例如传输前侦听信道(Listen Before Talk,LBT)、最大信道占用时间(Maximum Channel Occupancy Time,MCOT)等。
当通信设备需要发送信息时,要求先在指定的信道上执行LBT,对周围的无线传输环境进行能量检测(Energy Detection,ED),当检测得到的能量值低于预设门限时,信道被判断为空闲,此时才可以通过该信道进行传输,且传输的占用的信道时间不能超过MCOT;反之,则该信道被判断为繁忙,此时不可以通过该信道进行传输。
其中,通信设备可以是网络侧设备、UE、无线保真访问接入点(Wireless-Fidelity Access Point,Wi-Fi AP)等。
2、LBT
常用的LBT的类型(category)可以分为category 1,category 2和category4。
其中,针对Category 1:LBT是发送端不做LBT,即no LBT或者立即传输(immediate transmission)。
针对Category 2:LBT是一次LBT(one-shot LBT)即发送端在传输前做一次LBT,若发送端侦听到信道为空闲,则通过该信道进行传输,若发送端侦听到信道为繁忙,则不通过该信道进行传输。
针对Category 4:LBT是基于回退(back-off)的信道侦听机制,当发送端侦听到信道为繁忙,则进行回退,继续做侦听,直到侦听到信道为空。
目前,在57-71GHz非授权频段,考虑到波束赋形的影响以及隐藏节点问题,LBT又进一步被分为如下几种方式:
(Quasi-)Omni-directional LBT:采用全向或者准全向接收天线进行功率检测,也就是传统的LBT方式;
Directional LBT:采用方向性接收天线进行功率检测;
Wide-beam LBT:通过一个可以覆盖(cover)所有发送波束的宽的检测波束(sensing beam)在COT开始之前做LBT。需要说明的是,“cover”的定义方式还在讨论中。
Per-beam LBT:在COT开始之前,分别针对每一个发送波束做LBT。
3、传输配置指示(Transmission Configuration Indicator,TCI)状态(state)
网络侧设备可以使用无线资源控制(Radio Resource Control,RRC)信令为每个控制资源集(control resource set,CORESET)配置一个TCI状态或多个TCI状态,当配置多个TCI状态时,可以由媒体接入控制(Media Access Control,MAC)控制单元(Control Element,CE)指示或激活一个TCI state。这样,UE在监听某个波束方向上的信道时,可以对CORESET内的全部搜索空间(search space)使用相同准共址(Quasi-colocation,QCL),即相同的TCI state来监听该信道,也就是说,UE可以根据该TCI状态,确定使用哪个接收波束来接收该信道。
4、其他术语
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。

下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的参考信号处理方法、装置、终端及介质进行详细地说明。
图2示出了本申请实施例提供的一种参考信号处理方法的流程图。如图2所示,本申请实施例提供的参考信号处理方法可以包括下述的步骤101和步骤102。
步骤101、UE从网络侧设备接收目标指示信息。
可选地,本申请实施例中,上述目标指示信息具体可以为:COT指示信息。其中,该COT指示信息可以为:下行控制信息(Downlink Control Information,DCI),该DCI的格式可以为DCI 2_0。
可选地,本申请实施例中,目标指示信息中可以包括:COT的时域范围、COT的频域范围。
可选地,本申请实施例中,网络侧设备在信道占用时间内可发送的信号中可以包括参考信号。
其中,参考信号可以包括以下至少一项:同步信号块(Synchronous signal and PBCH block,SSB)、下行跟踪参考信号(Time ReferenceSignal,TRS)、信道状态信息参考信号(ChannelState Information Reference Signal,CSI-RS)、解调参考信号(Demodulation Reference Signal,DMRS)等。
本申请实施例中,上述第一空域范围是:根据第一信道的空域范围得到的,或根据空域指示信息得到的;该第一信道是:承载目标指示信息的信道,该空域指示信息为目标指示信息中包括的指示信息。
可以理解,UE可以通过第一信道得到第一空域范围,或者,可以从目标指示信息中得到第一空域范围。
在UE可以从目标指示信息中得到第一空域范围的情况下,该目标指示信息中还包括第一空域范围,即目标指示信息中包括:COT的时域范围、COT的频域范围和第一空域范围。
进一步可选地,本申请实施例中,第一信道可以为以下任一项:物理下行控制信道(Physical downlink control channel,PDCCH)、物理下行共享信道(Physical downlink shared channel,PDSCH)等。
步骤102、在第一空域范围和目标空域范围间满足预设条件的情况下,UE执行目标操作。
本申请实施例中,上述目标空域范围为:网络侧设备配置的参考信号的空域范围。
可选地,本申请实施例中,参考信号具体可以为:网络侧设备通过目标波束方向上的信道发送的参考信号。UE可以从网络侧设备接收该参考信号的相关配置,该相关配置中包括该参考信号的空域范围,从而UE可以确定第一空域范围和目标空域范围间是否满足预设条件。
可选地,本申请实施例中,上述预设条件包括:目标空域范围在第一空域范围内。
进一步可选地,本申请实施例中,上述预设条件具体可以包括以下一项或多项:
参考信号的时域范围,在COT的时域范围之内;
参考信号的频域范围,在COT的频域范围之内;
目标空域范围在第一空域范围内。
本申请实施例中,上述目标操作包括以下至少一项:从网络侧设备接收参考信号、测量参考信号。
本申请实施例中,若第一空域范围和目标空域范围间满足预设条件,则可以认为网络侧设备可发送的传输的第一空域范围覆盖通过某个波束方向上的信道发送的参考信号的目标空域范围,因此,UE可以从网络侧设备接收该参考信号,和/或测量该参考信号。
本申请实施例提供参考信号处理方法,UE可以从网络侧设备接收目标指示信息,以根据承载该目标指示信息的第一信道的空域范围(或该目标指示信息中包括的空域指示信息)得到第一空域范围,再确定该第一空域范围和网络侧设备配置的参考信号的目标空域范围间是否满足预设条件,从而在确定该第一空域范围和目标空域范围间满足预设条件的情况下,UE可以从网络侧设备接收该参考信号,和/或测量该参考信号。由于UE可以先从网络侧设备接收目标指示信息,以得到网络侧设备要发送信号的第一空域范围,这样UE可以确定该要发送的信号的第一空域范围、与网络侧设备配置的网络侧设备通过某个波束方向上的信道发送的参考信号的目标空域范围间是否满足预设条件,以确定该要发送的信号的波束范围是否覆盖通过某个波束方向上信道发送的参考信号的波束范围,并在确定该要发送的信号的波束范围覆盖通过某个波束方向上的信道发送的参考信号的波束范围的情况下,UE可以从网络侧设备接收该参考信号,和/或测量该参考信号,以进行RLM,因此,可以避免在网络侧设备在发送参考信号的波束方向上的Directional LBT失败,参考信号无法发送的情况下,UE仍在该波束方向上接收参考信号并进行RLM的问题,从而可以提升UE根据参考信号进行RLM的结果的准确性,如此,可以提升UE的通信质量。
以下将以四个不同的示例,举例说明。
针对示例1和示例2:
可选地,本申请实施例中,第一空域范围是:根据第一信道的空域范围得到的;该第一空域范围包括以下至少一项:

进一步可选地,本申请实施例中,第一类型具体可以为:Type D。
进一步可选地,本申请实施例中,参考信号的TCI状态中可以包括多个类型,每个类型对应至少一个QCL源参考信号,从而UE可以先确定参考信号的TCI状态中的第一类型对应的QCL源参考信号1,该参考信号1为参考信号的第一类型的第一级QCL源参考信号,该参考信号1的TCI状态中可以包括多个类型,每个类型对应至少一个QCL源参考信号;然后UE可以确定参考信号1的TCI状态中的第一类型对应的QCL源参考信号2,该参考信号2为参考信号的第一类型的第二级QCL源参考信号,该参考信号2的TCI状态中可以包括多个类型,每个类型对应至少一个QCL源参考信号;下来UE可以确定参考信号2的TCI状态中的第一类型对应的QCL源参考信号3,该参考信号3为参考信号的第一类型的第三级QCL源参考信号,该参考信号3的TCI状态中可以包括多个类型,每个类型对应至少一个参考信号,以此类推。
举例说明,如图3所示,假设参考信号为CSI-RS5,第一QCL源参考信号为SSB1,CSI-RS5的Type D第
一级QCL源参考信号为CSI-RS4,该CSI-RS4的Type D QCL源参考信号为CSI-RS1,则CSI-RS5的Type D第二级QCL源参考信号为CSI-RS1,以此类推,CSI-RS5的Type D第三级QCL源参考信号为SSB1,即CSI-RS5的Type D第三级QCL源参考信号与第一QCL源参考信号相同,这样,可以认为参考信号与第一QCL源参考信号间具有间接的Type D QCL关系。

本申请实施例提供的终端,由于终端可以先从网络侧设备接收目标指示信息,以得到网络侧设备要发送信号的第一空域范围,这样终端可以确定该要发送的信号的第一空域范围、与网络侧设备配置的网络侧设备通过某个波束方向上的信道发送的参考信号的目标空域范围间是否满足预设条件,以确定该要发送的信号的波束范围是否覆盖通过某个波束方向上信道发送的参考信号的波束范围,并在确定该要发送的信号的波束范围覆盖通过某个波束方向上的信道发送的参考信号的波束范围的情况下,终端可以从网络侧设备接收该参考信号,和/或测量该参考信号,以进行RLM,因此,可以避免在网络侧设备在发送参考信号的波束方向上的Directional LBT失败,参考信号无法发送的情况下,终端仍在该波束方向上接收参考信号并进行RLM的问题,从而可以提升终端根据参考信号进行RLM的结果的准确性,如此,可以提升终端的通信质量。

可选地,本申请实施例中,处理器110,还用于在第一空域范围和目标空域范围间不满足预设条件的情况下,取消执行目标操作。
如此可知,由于终端可以在确定网络侧设备要发送的传输的波束范围不覆盖通过某个波束方向上的信道发送的参考信号的波束范围的情况下,终端可以取消从网络侧设备接收该参考信号,和/或取消测量该参考信号,因此,可以避免在网络侧设备在发送参考信号的波束方向上的Directional LBT失败,参考信号无法发送的情况下,终端仍在该波束方向上接收参考信号并进行RLM的问题如此,可以提升终端的通信质量。
