Abstract
本公开是关于一种RS集合的配置方法、装置、设备及存储介质,属于通信技术领域。所述方法包括:终端获取信道测量结果;当信道测量结果满足预设条件时,终端向接入网设备发送测量报告;接入网设备根据测量报告对目标RS集合进行更新;接入网设备向终端发送RS集合更新信息。本公开通过终端获取信道测量结果,当信道测量结果满足预设条件时,向接入网设备发送测量报告,以便接入网设备根据测量报告及时地对目标RS集合进行更新,从而使得接入网设备一直为终端维持一个信道测量参数较大的目标RS集合,有助于降低波束失败发生的概率,或提高波束失败恢复的成功率。
Description
本公开实施例涉及通信技术领域,特别涉及一种RS(Reference Signal,参考信号)集合的配置方法、装置、设备及存储介质。
在5G NR(New Radio,新空口)系统中,接入网设备和终端可以使用波束(beam)收发信息。例如,接入网设备可以通过波束向终端发送PDCCH(Physical Downlink Control Channel,物理下行控制信道)的下行控制信息。
当终端发生移动或接入网设备的天线方向发生改变时,接入网设备配置给终端的用于接收下行控制信息的波束可能会发生波束失败(beam failure)的问题。目前,标准定义了一个用于检测波束失败的RS集合,当终端检测到该RS集合中所有RS对应的信道测量参数都低于第一门限值时,终端确定发生波束失败。
此时,终端可以根据接入网设备配置的用于确定候选波束(candidate beam)的RS集合,检测该用于确定候选波束的RS集合中是否存在L1-RSRP(Layer1-Reference Signal Received Power,层一的参考信号接收功率)大于第二门限值的RS,若存在这样的RS,则终端在该RS对应的随机接入时频资源上发送该RS对应的随机接入前导码,通过这种方式隐形地告知接入网设备该终端发生了波束失败,并找到了候选波束。随后终端检测接入网设备发送的针对波束失败请求的回复,等待波束失败恢复(beam failure recovery)。
当上述用于检测波束失败的RS集合和用于确定候选波束的RS集合中包含的各个RS对应的信道测量参数均较差时,会导致波束失败的发生概率增大,且波束失败恢复的成功率降低。

本公开实施例描述的网络架构以及业务场景是为了更加清楚地说明本公开实施例的技术方案,并不构成对本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本公开实施例提供的技术方案对于类似的技术问题,同样适用。

接入网设备110部署在接入网中。5G NR系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。接入网设备110与终端120之间通过某种空口技术互相通信,例如可以通过蜂窝技术相互通信。
接入网设备110可以是基站(Base Station,BS),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5G NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一名称可能会变化。为方便描述,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120的数量通常为多个,每一个接入网设备110所管理的小区内可以分布一个或多个终端120。终端120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、计算设备或连接到无线调制解调器的其它处理设备,以及各种形式的用户设备(User Equipment,UE),移动台(Mobile Station,MS),终端设备(terminal device)等等。为方便描述,本公开实施例中,上面提到的设备统称为终端。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统,但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统,也可以适用于5G NR系统后续的演进系统。
在本公开提供的技术方案中,通过终端获取信道测量结果,当信道测量结果满足预设条件时,向接入网设备发送测量报告,以便接入网设备根据测量报告及时地对目标RS集合进行更新,从而使得接入网设备一直为终端维持一个信道测量参数较大的目标RS集合,有助于降低波束失败发生的概率,或提高波束失败恢复的成功率。下面,将通过几个实施例,对本公开提供的技术方案进行介绍说明。
图2是根据一示例性实施例示出的一种RS集合的配置方法的流程图。该方法可应用于图1所示的网络架构中。该方法可以包括如下几个步骤。
在步骤201中,终端获取信道测量结果。
在本公开实施例中,信道测量结果包括:目标RS集合中包括的n个RS对应的信道测量参数,以及除上述目标RS集合之外的m个其它RS对应的信道测量参数,其中,n为正整数,m为正整数。
在一个示例中,目标RS集合是用于检测波束失败的RS集合。针对波束传输的场景,接入网设备可以为终端配置用于检测波束失败的RS集合。该用于检测波束失败的RS集合中包括至少一个RS,当该用于检测波束失败的RS集合中各个RS对应的信道测量参数满足波束失败的判定条件时,终端确定发生波束失败。
在另一个示例中,目标RS集合是用于检测无线链路失败(radio link failure)的RS集合。接入网设备还可以为终端配置用于检测无线链路失败的RS集合。该用于检测无线链路失败的RS集合可以包括上述用于检测波束失败的RS集合。该用于检测无线链路失败的RS集合中也可以包括至少一个RS,当该用于检测无线链路失败的RS集合中各个RS对应的信道测量参数满足无线链路失败的判定条件时,终端确定发生无线链路失败。
在又一个示例中,目标RS集合是在波束失败恢复过程中用于确定候选波束的RS集合。接入网设备还可以为终端配置用于确定候选波束的RS集合。该用于确定候选波束的RS集合中包括至少一个RS,当该用于确定候选波束的RS集合中存在信道测量参数较佳的RS时,终端找到候选波束。
在本公开实施例中,其它RS是作为候选RS,用于更新目标RS集合的RS。可选地,其它RS可以由接入网设备配置并告知给终端。
在本公开实施例中,信道测量参数可以包括以下至少一种:信道质量、L1-RSRP、L1-RSRQ(Layer 1-Reference Signal Received Quality,层一的参考信号的接收质量)、L1-SINR(Layer 1-Signal to Interference and Noise Ratio,层一的信号与干扰加噪声比)。当信道测量参数的类型为信道质量或L1-RSRQ或L1-SINR时,终端需要测量每个RS对应的RSRP以及干扰,需要说明的是,针对同一个RS对应的RSRP和干扰需要使用相同的接收波束来测量。
需要说明的是,终端需要获取哪些RS对应的信道测量参数,可以由接入 网设备配置并告知给终端。另外,终端需要获取哪种类型的信道测量参数,也可以由接入网设备配置并告知给终端。
此外,终端可以周期性地或者非周期性地获取信道测量结果。
在步骤202中,当信道测量结果满足预设条件时,终端向接入网设备发送测量报告。
预设条件是指预先设置好的触发终端向接入网设备发送测量报告的条件。预设条件可以由接入网设备配置并告知给终端。
在本公开实施例中,测量报告用于触发接入网设备对目标RS集合进行更新。
终端可以通过PUCCH(Physical Uplink Control Channel,物理上行控制信道)或PUSCH(Physical Uplink Shared Channel,物理上行共享信道)向接入网设备发送测量报告。
测量报告可以包括:k个RS的标识信息,以及k个RS对应的信道测量参数的指示信息,k为大于1的整数;其中,k个RS包括:n个RS以及m个其它RS中信道测量参数大于目标RS对应的信道测量参数的至少一个其它RS,目标RS是指n个RS中信道测量参数最小的RS。
RS的标识信息也称为RS index,用于唯一指示该RS。不同的RS对应于不同的标识信息。在本公开实施例中,RS可以是NZP CSI-RS(Non-Zero Power Channel State Information Reference Signal,非零功率信道状态信息参考信号),也可以是SSB(Synchronization Signal Block,同步信号块)。
可选地,预设条件包括以下任意一项:
1、信道测量结果所包括的各个RS对应的信道测量参数中,按由大到小的顺序排在前w个的RS与上一次获取的信道测量结果相比不同,w为正整数;
终端在上述步骤201中获取的信道测量结果可以称为本次获取的信道测量结果。上一次获取的信道测量结果即是在本次之前一次获取的信道测量结果。另外,w的取值可以预先设定,如由接入网设备配置,本公开实施例对此不作限定。
例如,目标RS集合包括以下RS:RS#1、RS#2和RS#3,其它RS包括RS#4和RS#5。上一次获取的信道测量结果中,按信道测量参数由大到小对各个RS进行排序依次为:RS#1、RS#2、RS#3、RS#4和RS#5。本次获取的信道测量结果中,按信道测量参数由大到小对各个RS进行排序依次为:RS#4、 RS#1、RS#2、RS#3和RS#5。假设w为3,由于前后两次排序结果中,前3个RS发生了改变,因此满足上述预设条件。此时,终端可以向接入网设备发送测量报告,该测量报告中可以包括目标RS集合中各个RS(也即RS#1、RS#2和RS#3)对应的信道测量参数的指示信息,还可以包括RS#4对应的信道测量参数的指示信息。
当信道测量结果满足这种预设条件时,说明信道测量参数较大的几个RS的排序发生了改变,此时终端向接入网设备发送测量报告,以便接入网设备根据测量报告对目标RS集合进行更新,如将信道测量参数较大的RS添加至目标RS集合中,并将信道测量参数较小的RS从目标RS集合中删除。
2、目标RS集合中存在至少一个RS对应的信道测量参数小于第一门限值;
其中,第一门限值可以预先设定,如由接入网设备配置或者由协议预先规定,本公开实施例对此不作限定。
例如,目标RS集合包括以下RS:RS#1、RS#2和RS#3,信道测量参数的类型为L1-RSRP。假设RS#1对应的L1-RSRP小于第一门限值,RS#2和RS#3对应的L1-RSRP不小于第一门限值。在这种情况下,信道测量结果满足上述预设条件。此时,终端可以向接入网设备发送测量报告,该测量报告中可以包括目标RS集合中各个RS(也即RS#1、RS#2和RS#3)分别对应的L1-RSRP的指示信息。
当信道测量结果满足这种预设条件时,说明目标RS集合中存在信道测量参数较小的RS,此时终端向接入网设备发送测量报告,以便接入网设备根据测量报告对目标RS集合进行更新,如将信道测量参数较小的RS从目标RS集合中删除。
3、目标RS集合中存在至少一个RS对应的信道测量参数与预设偏移值之和,小于m个其它RS对应的信道测量参数的最大值;
其中,预设偏移值可以预先设定,如由接入网设备配置或者由协议预先规定,本公开实施例对此不作限定。可选地,预设偏移值大于0。
例如,目标RS集合包括以下RS:RS#1、RS#2和RS#3,其它RS包括RS#4和RS#5,信道测量参数的类型为L1-RSRP。假设其它RS对应的L1-RSRP的最大值为RS#5对应的L1-RSRP,RS#2对应的L1-RSRP与预设偏移值之和小于RS#5对应的L1-RSRP,因此满足上述预设条件。此时,终端可以向接入网设备发送测量报告,该测量报告中可以包括目标RS集合中各个RS(也即 RS#1、RS#2和RS#3)对应的L1-RSRP的指示信息,还可以包括RS#5对应的L1-RSRP的指示信息。
当信道测量结果满足这种预设条件时,说明目标RS集合中存在信道测量参数较小的RS,且存在信道测量参数较大的其它RS,此时终端向接入网设备发送测量报告,以便接入网设备根据测量报告对目标RS集合进行更新,如将信道测量参数较大的其它RS添加至目标RS集合中,并将信道测量参数较小的RS从目标RS集合中删除。
4、m个其它RS中存在至少一个其它RS对应的信道测量参数大于第二门限值;
其中,第二门限值可以预先设定,如由接入网设备配置或者由协议预先规定,本公开实施例对此不作限定。
例如,其它RS包括RS#4和RS#5,信道测量参数的类型为L1-RSRP。假设RS#4对应的L1-RSRP大于第二门限值,RS#5对应的L1-RSRP不大于第二门限值。在这种情况下,信道测量结果满足上述预设条件。此时,终端可以向接入网设备发送测量报告,该测量报告中可以包括目标RS集合中各个RS对应的L1-RSRP的指示信息,以及RS#4对应的L1-RSRP的指示信息。
当信道测量结果满足这种预设条件时,说明存在信道测量参数较大的其它RS,此时终端向接入网设备发送测量报告,以便接入网设备根据测量报告对目标RS集合进行更新,如将信道测量参数较大的其它RS添加至目标RS集合中。5、目标RS集合中存在至少一个RS对应的信道测量参数小于第三门限值,且m个其它RS中存在至少一个其它RS对应的信道测量参数大于第四门限值。
其中,第三门限值和第四门限值可以预先设定,如由接入网设备配置或者由协议预先规定,本公开实施例对此不作限定。
例如,目标RS集合包括以下RS:RS#1、RS#2和RS#3,其它RS包括RS#4和RS#5,信道测量参数的类型为L1-RSRP。假设RS#2对应的L1-RSRP小于第三门限值,且RS#5对应的L1-RSRP大于第四门限值,因此满足上述预设条件。此时,终端可以向接入网设备发送测量报告,该测量报告中可以包括目标RS集合中各个RS(也即RS#1、RS#2、和RS#3)分别对应的L1-RSRP的指示信息,还可以包括RS#5对应的L1-RSRP的指示信息。
当信道测量结果满足这种预设条件时,说明目标RS集合中存在信道测量参数较小的RS,且存在信道测量参数较大的其它RS,此时终端向接入网设备 发送测量报告,以便接入网设备根据测量报告对目标RS集合进行更新,如将信道测量参数较大的其它RS添加至目标RS集合中,并将信道测量参数较小的RS从目标RS集合中删除。
在本公开实施例中,RS对应的信道测量参数的指示信息可用于表示该信道测量参数的大小。在一个示例中,测量报告中k个RS对应的信道测量参数的指示信息可以用如下方式表示:k个RS中,最优RS对应的信道测量参数的指示信息采用a个比特表示,最优RS是k个RS中信道测量参数最大的RS,a为正整数;k个RS中,除最优RS之外的每一个剩余RS对应的信道测量参数的指示信息采用b个比特表示,b为正整数。可选地,上述a个比特用于表示最优RS对应的信道测量参数的绝对值。另外,第i个剩余RS对应的信道测量参数的指示信息,用于指示第i个剩余RS对应的信道测量参数与最优RS对应的信道测量参数的差值,i为正整数。上述a、b的取值可以根据信道测量参数的类型及其对应的取值范围进行设定。例如,当信道测量参数为L1-RSRP时,a=7且b=4。
可选地,上述b个比特所形成的多种不同序列中,选用指定序列用于指示RS对应的信道测量参数小于预设阈值。例如,当b=4时,可以形成16种不同序列,假设选用“0000”用于指示RS对应的信道测量参数小于预设阈值。当某一RS对应的信道测量参数小于预设阈值时,说明该RS对应的波束发生波束失败。预设阈值可以根据信道测量参数的类型进行设定,例如当信道测量参数为L1-RSRP时,预设阈值设定为-140db。在这种方式下,当接入网设备从测量报告中发现某个RS对应的信道测量参数的指示信息采用指定序列表示时,即可以获知该RS对应的波束发生波束失败。后续,接入网设备可以将该RS从目标RS集合中删除。
可选地,测量报告还包括参数类型指示信息。如果有多种不同类型的信道测量参数供终端选用,则终端可以在测量报告中添加参数类型指示信息,用于指示信道测量参数的类型。
在步骤203中,接入网设备根据测量报告对目标RS集合进行更新。
在一个示例中,接入网设备在目标RS集合中增加至少一个RS,和/或,在目标RS集合中删除至少一个RS;其中,增加至目标RS集合中的RS对应的信道测量参数大于从目标RS集合中删除的RS对应的信道测量参数。
示例性地,假设接入网设备接收到的测量报告中,包括目标RS集合中包 含的各个RS(如RS#1、RS#2和RS#3)对应的信道测量参数的指示信息,以及至少一个其它RS(如RS#4)对应的信道测量参数的指示信息。如果接入网设备根据上述信息确定,RS#4对应的信道测量参数大于RS#2对应的信道测量参数,则接入网设备可以将RS#2从目标RS集合中删除,并将RS#4增加值目标RS集合中。
在步骤204中,接入网设备向终端发送RS集合更新信息。
RS集合更新信息用于指示更新后的目标RS集合中包括的RS。
在一个示例中,RS集合更新信息包括更新后的目标RS集合中的每一个RS的标识信息。
在另一个示例中,RS集合更新信息包括增加指示信息和/或删除指示信息,其中,增加指示信息用于指示需要增加至目标RS集合中的RS,删除指示信息用于指示需要从目标RS集合中删除的RS。
可选地,接入网设备通过RRC信令向终端发送RS集合更新信息。相应地,终端接收接入网设备发送的RS集合更新信息,并根据RS集合更新信息对目标RS集合进行更新。
可选地,接入网设备向终端发送配置信息。配置信息可以包括以下至少一项:测量对象配置信息、测量参数配置信息、报告触发配置信息、报告内容配置信息。测量对象配置信息用于指示需要获取信道测量参数的RS,例如测量对象配置信息可以包括目标RS集合所包含的各个RS的标识信息以及上文介绍的其它RS的标识信息。测量参数配置信息用于指示信道测量参数的类型,如告诉终端采用信道质量、L1-RSRP、L1-RSRQ和L1-SINR中的哪一种信道测量参数进行测量。报告触发配置信息用于指示终端向接入网设备发送测量报告所需满足的预设条件,可选地,该预设条件中包括上文介绍的各门限值或预设偏移值的取值。报告内容配置信息用于指示终端向接入网设备发送测量报告所需包含的内容,如告诉终端测量报告中需要包括各个RS的标识信息和信道测量参数的指示信息。相应地,终端接收接入网设备发送的配置信息,并根据该配置信息进行测量和上报。
综上所述,本公开实施例提供的技术方案中,通过终端获取信道测量结果,当信道测量结果满足预设条件时,向接入网设备发送测量报告,以便接入网设备根据测量报告及时地对目标RS集合进行更新,从而使得接入网设备一直为终端维持一个信道测量参数较大的目标RS集合,有助于降低波束失败发生的 概率,或提高波束失败恢复的成功率。
另外,终端在检测到信道测量结果满足预设条件时,才向接入网设备发送测量报告。相比于终端采用周期性、非周期性或者半静态的方式向接入网设备发送测量报告,采用本公开实施例提供的技术方案,终端在有必要的时候才向接入网设备发送测量报告,避免进行非必要的测量报告发送,有助于节省终端的信令开销。
在上述方法实施例中,仅从接入网设备和终端交互的角度进行介绍说明,上述有关接入网设备的步骤可以单独实现成为接入网设备一侧的RS集合的配置方法,上述有关终端的步骤可以单独实现成为终端一侧的RS集合的配置方法。

图5是根据一示例性实施例示出的一种接入网设备的结构示意图。
接入网设备500包括发射器/接收器501和处理器502。其中,处理器502也可以为控制器,图5中表示为“控制器/处理器502”。所述发射器/接收器501用于支持接入网设备与上述实施例中的所述终端之间收发信息,以及支持所述接入网设备与其它网络实体之间进行通信。所述处理器502执行各种用于与终端通信的功能。在上行链路,来自所述终端的上行链路信号经由天线接收,由接收器501进行解调(例如将高频信号解调为基带信号),并进一步由处理器502进行处理来恢复终端所发送到业务数据和信令消息。在下行链路上,业务数据和信令消息由处理器502进行处理,并由发射器501进行调制(例如将基带信号调制为高频信号)来产生下行链路信号,并经由天线发射给终端。需要说明的是,上述解调或调制的功能也可以由处理器502完成。例如,处理器502还用于执行上述方法实施例中接入网设备侧的各个步骤,和/或本公开实施例所描述的技术方案的其它步骤。

处理器603对终端600的动作进行控制管理,用于执行上述本公开实施例中由终端600进行的处理过程。例如,处理器603还用于执行上述方法实施例中的终端侧的各个步骤,和/或本公开实施例所描述的技术方案的其它步骤。
进一步的,终端600还可以包括存储器604,存储器604用于存储用于终端600的程序代码和数据。
