无线感知
目前的蜂窝网络(例如4G网络、5G网络)主要用于无线数据传输和通信。但是,其实蜂窝网络所使用的无线电磁波信号不但可以用于无线数据传输和通信,同时还具有环境感知能力,例如,无线电磁波信号能够用于用户的动作/手势识别、呼吸监测、终端设备移动速度测量、环境成像、天气监测等。因此,在未来的通信系统(比如,B5G系统、6G系统等)中,蜂窝网络除了用于数据传输和通信之外,还可以用于执行感知业务(或称,无线感知业务),比如,获取感知信息。无线感知的目标是获得感知目标的感知结果,例如,获得感知目标的速度、距离、移动方向、形状等一系列感知结果。
为了在通信系统中支持感知能力,作为一种实现方式,可以在通信系统中增加感知控制(sensing function,SF)网元以及相应的流程。如此一来,当应用层(或应用)将针对感知目标(例如,目标UE、目标物体等)的感知请求发送到核心网,核心网可以通过感知控制网元或者接入和移动性管理功能(access and mobility management function,AMF)选择合适的接入网设备或辅助UE,并触发接入网设备或辅助UE进行感知相关的无线测量能力,启动感知信息的测量,以便获得感知结果。
在一些实施例中,为了不引入过多的空口增强,通信系统可以考虑尽量复用现有的空口信号执行感知业务。例如,在B5G通感一体化的初期阶段,可以尽量复用现有的空口信号执行感知业务。
感知业务可以应用无线感知技术来执行。无线感知技术可以通过分析无线信号在传播过程中的变化,获得信号传播空间的特性,以实现环境或场景的感知。鉴于无线通信技术与无线感知技术的过程比较相似,因此,可以将无线通信技术和无线感知技术结合起来,在实现通信的同时对周围的环境进行感知。在一些实施例中,无线通信技术和无线感知技术的结合可以理解为通感一体化。
通感一体化的无线感知场景有多种,下面结合图2A至图2F对通感一体化主要的无线感知场景进行示例性介绍。需要说明的是,下述场景仅仅是一些示例,本申请的技术方案可以应用于下述场景中,但是下述场景并不用于对本申请的技术方案形成限定,对于其他应用场景本申请仍然适用。
参见图2A,图2A是本申请实施例提供的一个应用场景的示意图。图2A是针对通信系统中的基站既作为感知信号的发送端又作为感知信号的接收端的情况的一个示例,因此,图2A对应的感知链路也可以称为基站回波感知链路。在图2A中,基站可以发送感知信号,感知信号经过感知目标(比如,周边环境中的汽车)反射回基站。这样,基站可以对感知信号进行感知测量,得到感知结果。
参见图2B,图2B是本申请实施例提供的另一个应用场景的示意图。图2B是针对两个基站分别作为感知信号的发送端和感知信号的接收端的情况的一个示例,因此,图2B对应的感知链路也可以称为基站间感知链路。在图2B中,基站A可以发送感知信号,感知信号经过感知目标(比如,周边环境中的汽车)反射到基站B。这样,基站B可以对感知信号进行感知测量,得到感知结果。
参见图2C和图2D,图2C和图2D是本申请实施例提供的又一个应用场景的示意图。图2C和图2D是针对基站和UE分别作为感知信号的发送端和感知信号的接收端的情况的一个示例,因此,图2C和图2D对应的感知链路也可以称为空口感知链路。图2C为空口上行感知链路的一个示例,在图2C中,UE可以发送感知信号,感知信号经过感知目标(比如,周边环境中的汽车)反射到基站。这样,基站可以对感知信号进行感知测量,得到感知结果。图2D为空口下行感知链路的一个示例,在图2D中,基站可以发送感知信号,感知信号经过感知目标(比如,周边环境中的汽车)反射到UE。这样,UE可以对感知信号进行感知测量,得到感知结果。
参见图2E,图2E是本申请实施例提供的又一个应用场景的示意图。图2E是针对通信系统中的UE既作为感知信号的发送端又作为感知信号的接收端的情况的一个示例,因此,图2E对应的感知链路也可以称为UE回波感知链路。在图2E中,UE可以发送感知信号,感知信号经过感知目标(比如,周边环境中的汽车)反射回UE。这样,UE可以对感知信号进行感知测量,得到感知结果。
参见图2F,图2F是本申请实施例提供的又一个应用场景的示意图。图2F是针对两个UE分别作为感知信号的发送端和感知信号的接收端的情况的一个示例,因此,图2F对应的感知链路也可以称为UE间感知链路。在图2F中,UE A可以发送感知信号,感知信号经过感知目标(比如,周边环境中的汽车)反射到UE B。这样,UE B可以对感知信号进行感知测量,得到感知结果。
波束赋形
波束赋形是在5G中引入的一项新的技术,引入波束赋形之后,基站和终端设备均可以使用在某特定空间方向上能量集中的波束进行通信信号的发送和接收。
由于波束赋形之后,波束的覆盖范围变窄,因此,基站和终端设备需要确定发送接收波束对以便在特定方向上成功接收或发送通信信号。为了确定发送端发送波束和接收端接收波束的“波束对”,例如,确定基站下行发送和UE接收波束的“波束对”,发送端和接收端可以分别以波束扫描的方式来确定“最佳发送接收波束对”。作为一种实现方式,发送端和接收端可以通过下面的实现方式确定“最佳发送接收波束对”。
在步骤1,在给定接收端波束的情况下,发送端的波束被扫描,接收端可以根据测量到的多个发送波束的参考信号接收功率(reference signal received power,RSRP)来确定候选发送波束,并上报给发送端。
在步骤2,在给定发送端波束的情况下,接收端的波束被扫描,接收端可以根据多个接收波束测量到的发送波束的RSRP来确定候选接收波束,并上报给发送端。
在一些实施例中,基站可以采用方向不变的波束向UE发送多次通信信号(比如,参考信号)。在一些实施例中,基站可以采用不同的波束向UE发送通信信号。
作为一种实现方式,UE可以根据NZP-CSI-RS-ResourceSet信息元素(information element,IE)来确定基站采用方向不变的波束还是采用不同的波束发送通信信号。示例性地,当基站将NZP-CSI-RS-ResourceSet中的重复IE(repetition IE)设为“关闭(off)”时,UE即知道基站在发送通信信号时使用的是不同的波束;反之,当基站将repetition IE设为“开启(on)”时,UE即知道基站在发送通信信号时采用的是方向不变的波束。
NZP-CSI-RS-ResourceSet IE是一组非零功耗(non-zero-power,NZP)信道状态信息参考信号(channel state information reference signal,CSI-RS)资源(即NZP CSI-RS的ID)和组级别的参数的集合。为了便于理解,下面给出NZP-CSI-RS-ResourceSet IE的一个示例。
如果基站在发送给UE的参考信号配置中告知UE某资源集中的多个NZP CSI-RS资源的发送波束是变化的,那么当UE接收到该信息后,UE可以开启对发送波束的扫描(接收波束不进行变化),以确定最优的发送波束。后续,当NZP-CSI-RS-ResourceSet IE中的repetition IE设置为“on”后,UE可以进行接收波束的扫描,以确定最优的接收波束。基于此,基站和UE之间可以确定最佳的发送接收波束对。在一些实施例中,根据信道互易性,接收信号质量最好的波束也可以作为数据发送的波束进行使用。
波束指示
如果UE和基站之间同时维护多个发送天线和接收天线对,那么基站下行发送物理下行共享信道(physical downlink shared channel,PDSCH)或物理下行控制信道(physical downlink control channel,PDCCH)时,可以选择使用哪个发送天线。这种情况下,基站可以将该信息发送给UE,以便UE切换至与基站选择的发送天线相匹配的接收天线,这种机制可以称为波束指示。也就是说,基站可以向UE发送波束指示信息,以便UE确定合适的接收波束。
在一些实施例中,波束指示可以通过传输配置指示(transmission configuration indicator,TCI)状态和准共址(quasi-co-location,QCL)概念来实现。作为一种实现方式,基站可以通过高层信令为UE配置一组TCI状态,之后,基站可以向UE发送TCI激活信令,使得UE可以确定接收PDCCH或PDSCH所对应的TCI状态ID,从而确定接收PDCCH或PDSCH的波束信息。
在一些实施例中,基站为UE配置的一组TCI状态中的每个TCI状态对应一组参考信号,比如,CSI-RS或同步信息块(synchronization signal/PBCH block,SSB)ID,以表示PDSCH和PDCCH传输的空间滤波(或称,波束)的特征与上述参考信号之一匹配。
作为一种实现方式,TCI状态可以包括如下配置中的一项或多项:TCI状态标识(identifier,ID);QCL信息1;以及QCL信息2。TCI状态ID可以用于标识TCI状态。QCL信息(比如,QCL信息1,QCL信息2等)可以包括:QCL类型配置和QCL参考信号配置。
在一些实施例中,QCL类型配置可以是QCL类型A、QCL类型B、QCL类型C或QCL类型D中的一种。不过本申请实施例并不限定于此,在QCL类型包括其他类型的情况下,该QCL类型配置也可以是其他类型。
在一些实施例中,QCL参考信号配置可以包括以下信息中的一种或多种:参考信号所在的小区ID,带宽部分(bandwidth part,BWP)ID,以及参考信号的标识。以参考信号为CSI-RS或SSB为例,参考信号的标识例如可以是CSI-RS资源标识或SSB编号。
作为一种实现方式,TCI-State IE可以将一个或两个下行参考信号与相应的QCL类型相关联,以利用TCI状态进行波束指示。
为了便于理解,下面给出TCI-State IE的一个示例。

TCI状态的激活/去激活
网络可以通过发送特定于UE的PDSCH的TCI状态激活/去激活媒体接入控制控制单元(medium access control control element,MAC CE),以激活和去激活为服务小区或一组服务小区的PDSCH配置的TCI状态,该服务小区或一组服务小区是通过simultaneousTCI-UpdateList1或simultaneousTCI-UpdateList2字段配置的。网络可以通过发送特定于UE的PDSCH的增强TCI状态激活/去激活MAC CE,以激活和去激活为服务小区的PDSCH指示的下行控制信息(downlink control information,DCI)传输配置指示字段的码点(codepoint)配置的TCI状态。为PDSCH配置的TCI状态在上层(重新)配置和同步重新配置后被去激活。
在TCI状态的激活/去激活过程中,MAC实体应该执行以下步骤。
1>如果MAC实体在服务小区接收到特定于UE的PDSCH的TCI状态激活/去激活MAC CE:
2>MAC实体向下层指示有关特定于UE的PDSCH的TCI状态激活/去激活MAC CE的信息。
1>如果MAC实体在服务小区接收到特定于UE的PDSCH的增强TCI状态激活/去激活MAC CE:
2>MAC实体向下层指示有关特定于UE的PDSCH的增强TCI状态激活/去激活MAC CE的信息。
如前文所述,蜂窝网络可以用于执行感知业务。在利用蜂窝网络执行感知业务的场景下,感知信号的发送端/接收端需要在波束上发送或接收感知信号,那么,发送端/接收端如何确定发送或接收感知信号的波束是需要解决的问题。尤其在移动场景下,感知信号的发送端/接收端可能与感知目标之间的相对位置会发生变化,用于发送或接收感知信号的波束也需要对应调整,那么,发送端/接收端在不同位置时,如何确定发送或接收感知信号的波束仍然是亟需解决的问题。
针对上述问题,本申请实施例提供一种无线通信的方法和装置,使得感知信号的发送端/接收端能够基于第一信息确定发送/接收感知信号的第一波束,有利于保证确定的第一波束更为准确,从而为第一波束更好地冲向感知目标提供了基本条件。
下面结合图3至图6对本申请的方法实施例进行详细介绍。
图3为本申请一实施例提供的无线通信的方法的流程示意图。图3所示的方法是站在第一通信设备和第二通信设备交互的角度进行描述的。下面先对第一通信设备和第二通信设备分别进行介绍。
第一通信设备是指感知信号的发送端或接收端。或者说,第一通信设备可以发送或接收感知信号。此外,第一通信设备也可以理解为下文提及的第一信息的接收端。第二通信设备是指第一信息的发送端。
在一些实施例中,如果第一通信设备是感知信号的发送端,第二通信设备可以是感知信号的接收端,即感知信号的接收端可以向感知信号的发送端发送第一信息。
在一些实施例中,如果第一通信设备是感知信号的接收端,第二通信设备可以是感知信号的发送端,即感知信号的发送端可以向感知信号的接收端发送第一信息。
不过本申请实施例并不限定于此,第一信息也可以是除感知信号的发送端/接收端之外的其他通信设备向第一通信设备发送的,即第二通信设备也可以是除感知信号的发送端/接收端之外的其他通信设备。例如,第二通信设备可以是核心网设备,比如AMF网元、SF网元等。
在一些实施例中,第一通信设备可以是终端设备(例如,图1所示的终端设备120),第二通信设备可以是以下中的一种:接入网设备(例如,图1所示的接入网设备110)、核心网设备、终端设备。以感知信号的发送端和接收端是终端设备和接入网设备(比如,终端设备向接入网设备发送感知信号,或者,接入网设备向终端设备发送感知信号)为例,在一些实施例中,接入网设备可以向终端设备发送第一信息,以便终端设备确定发送或接收感知信号的波束(即下文的第一波束);在一些实施例中,核心网设备可以向终端设备发送第一信息,以便终端设备确定发送或接收感知信号的波束。以感知信号的发送端和接收端均是终端设备为例,在一些实施例中,接入网设备或核心网设备可以向终端设备发送第一信息;在一些实施例中,发送感知信号的终端设备可以向接收感知信号的终端设备发送第一信息或接收感知信号的终端设备可以向发送感知信号的终端设备发送第一信息。
在一些实施例中,第一通信设备可以是接入网设备(例如,图1所示的接入网设备110),第二通信设备可以是以下中的一种:接入网设备、核心网设备。以感知信号的发送端和接收端是终端设备和接入网设备(比如,终端设备向接入网设备发送感知信号,或者,接入网设备向终端设备发送感知信号)为例,在一些实施例中,核心网设备可以向接入网设备发送第一信息,以便接入网设备确定发送或接收感知信号的波束。以感知信号的发送端和接收端均是接入网设备为例,在一些实施例中,核心网设备可以向接入网设备发送第一信息;在一些实施例中,发送感知信号的接入网设备可以向接收感知信号的接入网设备发送第一信息或接收感知信号的接入网设备可以向发送感知信号的接入网设备发送第一信息。
本申请实施例提及的核心网设备可能是多种,本申请实施例对此并不限定。例如,在一些实施例中, 核心网设备可以是SF网元。或者,在一些实施例中,核心网设备可以是AMF网元等。
图3所示的方法包括步骤S310,下面对步骤S310进行介绍。
在步骤S310,第一通信设备接收第一信息。该第一信息用于确定第一波束。
第一波束可以用于发送或接收感知信号,即第一波束是用于发送或接收感知信号的波束。或者说,第一波束可以用于执行感知业务。
在一些实施例中,本申请实施例提及的波束(比如,第一波束)也可以称为空域滤波器(spatial domain filter)、空域参数(spatial domain parameter)或者其他名称。为了便于理解,本申请实施例主要以波束为例介绍,波束与空域滤波器、空域参数等可以相互替换使用。
在一些实施例中,第一波束可以与第一通信设备发送/接收通信信号的波束不同。
在一些实施例中,第一波束可以与第一通信设备发送/接收通信信号的波束相同。
本申请实施例中,第一波束是利用第一信息确定的。第一通信设备根据第一信息确定第一波束,有利于保证确定的第一波束更为准确,从而为第一波束更好地冲向感知目标提供了基本条件。
在一些实施例中,第一信息可以是第二通信设备发送给第一通信设备的。
在一些实施例中,第一信息可以用于指示第一波束。例如,第一信息可以包括第一波束对应的第一波束指示信息。如此一来,第一通信设备可以根据第一波束指示信息确定用于发送或接收感知信号的第一波束。
在一些实施例中,第一信息可以用于指示感知目标的位置信息。在一些实施例中,感知目标(例如,感知UE、感知物体等)也可以称为被感知目标、待感知目标等其他名称,本申请实施例对此并不限定。
为了便于理解,下文结合实施例一和实施例二,分别以第一信息用于指示第一波束和第一信息用于指示感知目标的位置信息为例,对第一信息进行详细介绍。
实施例一:
实施例一中,第一信息可以用于指示第一波束。作为一种实现方式,第一信息可以利用波束指示信息来指示第一波束。例如,第一信息可以包括第一波束对应的第一波束指示信息,以便通过第一波束指示信息向第一通信设备指示第一波束。
在一些实施例中,第一信息与第一通信设备发送或接收通信信号的第二波束指示信息不同。或者说,第一波束指示信息与第一通信设备发送或接收通信信号的第二波束指示信息不同。如此一来,第二通信设备可以通过第一信息为第一通信设备配置单独用于发送或接收感知信号的波束指示信息,或者通过第一信息为第一通信设备配置与用于发送或接收通信信号不同的(独立的)波束指示信息,以避免采用发送或接收通信信号的波束指示信息来发送或接收感知信号导致的传输性能差的问题。以终端设备和接入网设备执行感知业务为例,在终端设备和接入网设备的空间关系与感知目标和终端设备之间的空间关系不同的情况下,第二通信设备(比如,接入网设备)可以为第一通信设备(比如,终端设备)配置单独的用于执行感知业务的波束指示信息,以提升传输性能。
在一些实施例中,第一信息与第一通信设备发送或接收通信信号的第二波束指示信息相同。或者说,第一波束指示信息与第一通信设备发送或接收通信信号的第二波束指示信息相同。如此一来,第一通信设备可以复用用于发送或接收通信信号的波束来发送或接收感知信号。以终端设备和接入网设备执行感知业务为例,在终端设备和接入网设备的空间关系与感知目标与终端设备之间的空间关系相同的情况下,终端设备可以复用接入网设备指示的第二波束指示信息,以节省信令开销。
在一些实施例中,第一波束指示信息可以是利用TCI状态来指示的。例如,第一波束指示信息可以包括以下配置中的一项或多项:TCI状态ID,QCL参考信号的标识,以及QCL类型。
在一些实施例中,QCL参考信号的标识可以是利用SSB编号来标识的。在一些实施例中,QCL参考信号的标识可以是利用CSI-RS标识来标识的,本申请实施例对此并不限定。
本申请实施例对第一信息的承载方式不做限定。示例性地,第一信息可以承载于以下中的一种或多种:非接入层(non-access stratum,NAS)信令,无线资源控制(radio resource control,RRC)信令,MAC CE信令,以及接入网设备之间的接口。
本申请实施例对NAS信令的具体类型不做限定,示例性地,NAS信令可以为信号感知辅助消息。也就是说,第二通信设备可以通过信号感知辅助消息将第一信息发送给第一通信设备。
本申请实施例对接入网设备之间的接口不做具体限定,示例性地,接入网设备之间的接口例如可以是Xn接口或者NG接口等。
作为一个示例,第一通信设备为终端设备,第二通信设备为接入网设备,则第一信息可以承载于RRC信令或MAC CE信令中。
作为另一个示例,第一通信设备为终端设备,第二通信设备为核心网设备,则第一信息可以承载于NAS信令中。
作为又一个示例,第一通信设备和第二通信设备均为接入网设备,则第一信息可以通过接入网设备之间的接口传输。
在一些实施例中,第一信息可以是预配置的。例如,第一信息可以是第二通信设备预配置的。
在一些实施例中,第一信息可以包括一个波束指示信息,该波束指示信息即为第一波束指示信息。这种情况下,第一通信设备接收第一信息后,便可以根据第一波束指示信息确定第一波束,或者说,可以基于第一波束指示信息对应的第一波束发送/接收感知信号。
在一些实施例中,第一信息可以包括多个候选波束指示信息,或者说,第一信息可以包括候选波束集或候选波束列表。该多个候选波束指示信息中包括第一波束对应的第一波束指示信息,即第一波束指示信息属于该多个候选波束指示信息。
在一些实施例中,在第一信息包括多个候选波束指示信息的情况下,第一通信设备还可以进一步基于第二信息确定第一波束对应的第一波束指示信息。下面结合图4对此进行介绍。
图4为本申请另一实施例提供的无线通信方法的流程示意图。如图4所示,该方法可以包括步骤S410和步骤S420。
在步骤S410,第一通信设备接收第一信息。第一信息用于确定第一波束。
该第一信息包括多个候选波束指示信息。或者说,第一信息可以用于指示或配置多个候选波束指示信息。
关于步骤S410中的第一信息和第一波束的其他描述可以参见前文对步骤S310的介绍,为了简洁,此处不再赘述。
在步骤S420,第一通信设备接收第二信息。该第二信息用于指示第一波束指示信息。
也就是说,在第一信息指示多个候选波束指示信息的情况下,第二信息可以用于激活该多个候选波束指示信息中的一个或多个作为第一波束对应的第一波束指示信息。
本申请实施例对第二信息的承载方式不做限定。示例性地,第二信息可以承载于第一信令中,第一信令可以包括以下中的一种或多种:MAC CE信令,RRC信令,侧行控制信息(sidelink control information,SCI),以及接入网设备之间的接口。
作为一个示例,第一通信设备为终端设备,第二通信设备为接入网设备,则第二信息可以承载于MAC CE信令或RRC信令中。不过本申请实施例并不限定于此,例如,第二信息还可以承载于DCI中。
作为另一个示例,第一通信设备和第二通信设备均为终端设备,则第二信息可以承载于SCI中。
作为又一个示例,第一通信设备和第二通信设备均为接入网设备,则第二信息可以通过接入网设备之间的接口传输。
在一些实施例中,第二信息可以是第二通信设备发送给第一通信设备的。也就是说,在一些实施例中,第一信息和第二信息可以是同一通信设备发送给第一通信设备的。
在一些实施例中,第二信息可以利用TCI状态ID来指示第一波束指示信息。
在一些实施例中,承载第二信息的信令可以是单独配置的。以承载第二信息的信令为MAC CE信令为例,第二通信设备可以单独配置一个MAC CE信令来指示第一波束指示信息。
在一些实施例中,用于配置第一波束指示信息的信令与用于配置第二波束指示信息(第二波束指示信息用于指示第一通信设备发送或接收通信信号的波束)的信令不同。例如,用于配置第一波束指示信息的信令可以为MAC CE信令,用于配置第二波束指示信息的信令可以为RRC信令。或者,用于配置第一波束指示信息的信令和用于配置第二波束指示信息的信令均可以是MAC CE信令,但两者是不同的MAC CE信令。
在一些实施例中,用于配置第一波束指示信息的信令与用于配置第二波束指示信息的信令不同可以理解为,用于配置第一波束指示信息的信令与用于配置第二波束指示信息的信令对应不同的逻辑信道号。以用于配置第一波束指示信息的信令与用于配置第二波束指示信息的信令均为MAC CE信令为例,两者可以具有不同的逻辑信道号。
在一些实施例中,第一信息的获取或更新可以是基于第一通信设备的请求进行的。图5为本申请又一实施例提供的无线通信的方法的流程示意图,参见图5,图5的方法可以包括步骤S510和步骤S520。
在步骤S510,第一通信设备发送第一请求。第一请求用于获取或更新第一信息。
在一些实施例中,第一请求可以是第一通信设备向第二通信设备发送的。
在一些实施例中,第一请求可以承载于以下信令中的一种或多种:MAC CE信令,NAS信令,RRC信令,SCI,以及接入网设备之间的接口。以第一通信设备为终端设备,第二通信设备为接入网设备为例,第一请求可以承载于上行MAC CE信令或上行RRC信令中,当然,在一些实施例中,第一请求也可以承载于上行控制信息(uplink control information,UCI)中。以第一通信设备为终端设备,第二通信设备为核心网设备为例,第一请求可以承载于上行NAS信令中。
在一些实施例中,第一请求用于获取或更新第一信息可以是指,第一请求可以用于获取或更新多个候选波束指示信息。在一些实施例中,第一请求用于获取或更新第一信息可以是指,第一请求可以用于获取或更新第一通信设备当前应用的波束指示信息(即,第一波束指示信息)。
在一些实施例中,第二通信设备接收第一通信设备发送的第一请求之后,可以为第一通信设备发送或更新第一信息,比如,更新多个候选波束指示信息,或者,更新第一通信设备当前应用的波束指示信息等。
在多种情况下,第一通信设备可能会发送第一请求,以获取或更新第一信息,本申请实施例对第一通信设备发送第一请求的情况不做具体限定。示例性地,在信道状态变化或第一通信设备的状态变化的情况下,第一通信设备可以发送第一请求。
作为一个示例,当信道状态发生变化或变化大于某一阈值时,第一通信设备可以发送第一请求。本申请实施例对信道状态的变化的类型不做限定,例如,通过某一信道接收的感知信号的视距(line of sight,LOS)情况发生恶化(比如,LOS值指示降低)时,第一通信设备可以发送第一请求。
作为另一个示例,当第一通信设备的状态发生变化或变化大于某一阈值时,第一通信设备可以发送第一请求。本申请实施例对第一通信设备的状态变化的类型不做限定,例如,第一通信设备的位置改变或改变超过某一阈值时,第一通信设备可以发送第一请求;或者,第一通信设备的服务小区的小区参考信号接收功率(reference signal receiving power,RSRP)变化或变化超过某一阈值时,第一通信设备可以发送第一请求等。
在步骤S520,第一通信设备接收第一信息。
关于步骤S520的详细介绍,可以参见前文对步骤S310或步骤S410的介绍,为了简洁,此处不再赘述。
在一些实施例中,在第一信息包括多个候选波束指示信息的情况下,第一通信设备还可以接收第二信息,第二信息用于指示第一波束指示信息。或者说,第二信息可以用于指示激活使用第一波束指示信息,或指示激活使用第一波束指示信息对应的波束(第一波束)。
在一些实施例中,第二通信设备可以更新第一信息,例如,主动更新第一信息。作为一种实现方式,第二通信设备可以通过即时的RRC信令或MAC CE信令对第一信息进行更新(比如,更新第一通信设备的多个候选波束指示信息,或者更新第一通信设备当前使用的波束指示信息)。
在一些实施例中,第一波束的改变或更新(或称,第一信息的改变或更新)是在第一通信设备和感知目标之间的相对位置变化的情况下发生的。例如,第一波束的改变或更新是在第一通信设备的位置发生变化的情况下发生的。再如,第一波束的改变或更新是在感知目标的位置发生变化的情况下发生的。又如,第一波束的改变或更新是在第一通信设备和感知目标的位置均发生变化的情况下发生的。
在一些实施例中,用于发送或接收感知信号的波束指示信息可以与多种信息关联。例如,用于发送或接收感知信号的波束指示信息可以与以下中的一种或多种关联(对应):地理位置信息,以及时域资源信息。
在一些实施例中,也可以理解为,第一信息可以与多种信息关联,例如,可以与以下中的一种或多种关联:第一地理位置,以及第一时域资源。
以第一信息包括多个候选波束指示信息为例,该多个候选波束指示信息可以与不同地理位置和/或不同时域资源相关联。
也就是说,用于发送或接收感知信号的波束指示信息可以与不同地理位置或不同时域资源存在绑定关系,即不同地理位置绑定有不同的用于发送或接收感知信号的波束,或者不同时域资源绑定有不同的用于发送或接收感知信号的波束。
在第一通信设备移动的场景中,第一通信设备可以在不同地理位置(多个地理位置)之间移动。该不同地理位置包括第一地理位置,其中,第一地理位置与第一波束(或第一波束指示信息)对应。
在一些实施例中,该不同地理位置中的一个地理位置与用于发送或接收感知信号的波束(或波束指示信息)之间存在关联关系或对应关系。如此一来,当第一通信设备移动至不同地理位置时,可以应用移动至的地理位置对应的波束来发送或接收感知信号。或者说,当第一通信设备移动至不同地理位置时,可以应用不同的波束来发送或接收感知信号。图6示出了第一通信设备移动过程中使用不同的波束来发送或接收感知信号的一个示例。
在一些实施例中,该不同地理位置中的一个地理位置对应一个用于发送或接收感知信号的波束。也就是说,地理位置与用于发送或接收感知信号的波束之间存在一一对应的关系。如此一来,当第一通信设备移动至不同地理位置时,可以直接应用该地理位置对应的唯一的波束来发送或接收感知信号。
在一些实施例中,该不同地理位置中的一个地理位置对应多个用于发送或接收感知信号的波束。也就是说,地理位置与用于发送或接收感知信号的波束之间存在一对多的对应关系。
在一些实施例中,在一个地理位置对应多个用于发送或接收感知信号的波束的情况下,第一通信设备还可以接收激活信息,该激活信息用于指示该一个地理位置对应的多个用于发送或接收感知信号的波束中的一个,以便第一通信设备基于该激活信息对应的波束来发送或接收感知信号。
在一些实施例中,第一通信设备可以根据当前驻留的地理位置范围确定用于发送或接收感知信号的波束。例如,第一通信设备可以根据当前驻留的地理位置范围确定第一波束指示信息。
在一些实施例中,地理位置与用于发送或接收感知信号的波束之间的关联关系或对应关系可以是预配置的。例如,可以是网络预配置的;或者,可以是第二通信设备预配置的,等等。
本申请实施例对不同地理位置(或者,第一地理位置)的范围的划分粒度不做限定。示例性地,不同地理位置的范围可以是基于以下粒度中的一种或多种确定的:小区(cell),SSB,无线接入网通知区域(RAN-based notification area,RNA),跟踪区域(tracking area,TA),以及跟踪区域列表(TA list)。也就是说,不同地理位置的范围可以是按照不同的小区区分的,或者可以是按照不同的SSB区分的,又或者可以是按照不同的RNA区分的,也可以是按照不同的TA或TA列表区分的。当然,本申请实施例并不限定于此,在一些实施例中,不同地理位置的范围还可以是按照不同区域单位混合确定的,例如,不同地理位置的范围可以是按照小区和SSB混合区分的,或者,不同地理位置的范围可以是按照小区、RNA、TA混合区分的,等等。
在一些实施例中,第一通信设备可以根据以下中的一种或多种确定用于发送或接收感知信号的波束:当前驻留或接入的小区ID、RNA ID、TA ID、当前无线信号测量结果最高的SSB、第一通信设备选择的SSB。例如,第一通信设备可以根据当前驻留或接入的小区ID确定用于发送或接收感知信号的波束。或者,第一通信设备可以根据第一通信设备当前驻留或接入的RNA ID确定用于发送或接收感知信号的波束。又或者,第一通信设备可以根据当前驻留或接入的小区ID和TA ID确定用于发送或接收感知信号的波束,等等。
在一些实施例中,不同地理位置可以对应不同的用于发送或接收感知信号的波束可以是指,不同地理位置对应的TCI状态不同,例如,TCI状态中包含的参考信号(如,参考信号的标识)是不同的。
在一些实施例中,TCI状态中包含的参考信号可以是第一通信设备的服务小区发送的。在一些实施例中,TCI状态中包含的参考信号可以是其他服务小区发送的。
实施例二:
实施例二中,第一信息可以用于指示感知目标的位置信息。第一信息用于指示感知目标的位置信息的实现方式有多种,本申请实施例对此并不限定。在一些实施例中,第一信息可以用于直接指示感知目标的位置信息。例如,第一信息可以包括感知目标的位置信息。在一些实施例中,第一信息可以用于间接指示感知目标的位置信息。例如,第一信息可以利用感知目标附近的通信设备的位置信息或感知目标携带的通信设备的位置信息来间接指示感知目标的位置信息。
为了便于理解,下面给出第一信息用于指示感知目标的位置信息的两种具体实现方式。
实现方式1:直接指示感知目标的位置信息
作为一种实现方式,第一信息可以包括感知目标的位置信息,以便第一通信设备根据感知目标的位置信息确定用于发送或接收感知信号的波束。
在一些实施例中,第一信息包括感知目标的位置信息可以是指,第一信息可以包括感知目标的物理位置信息。
本申请实施例对感知目标的物理位置信息的表示方式不做限定。在一些实施例中,感知目标的物理位置信息可以利用绝对坐标或相对坐标的方式来表示。在一些实施例中,感知目标的物理位置信息可以利用感知目标的经纬度坐标来表示。在一些实施例中,感知目标的物理位置信息可以利用极坐标的方式来表示等。
在一些实施例中,第一信息包括感知目标的位置信息可以是指,第一信息可以包括感知目标所处的位置区域的信息。例如,第一信息可以包括感知目标所处的位置区域的ID(zone ID)。
在一些实施例中,感知目标所处的位置区域可以是预定义的,例如协议预定义的。
本申请实施例对感知目标所处的位置区域的划分方式不做具体限定。例如,感知目标所处的位置区域可以是按照小区(cell)划分的。或者,感知目标所处的位置区域可以是按照跟踪区域(tracking area,TA)划分的。又或者,感知目标所处的位置区域可以是按照SSB划分的等。
如此一来,第一通信设备可以根据自身的位置信息以及感知目标的位置信息,确定合适的用于发送或接收感知信号的波束。
本申请实施例对第一通信设备获取自身的位置信息的方式不做具体限定。例如,第一通信设备可以通过全球导航卫星系统(global navigation satellite system,GNSS)获取自身的位置信息。或者,第一通信设备可以基于某些定位方法获取自身的位置信息,比如,基于依赖于无线接入技术(radio access  technology,RAT)的定位方法等。本申请实施例对依赖于RAT的定位方法不做限定,例如,可以包括下行到达时间差的定位方法、上行到达时间差的定位方法、多小区往返时间(round trip time,RTT)的定位方法等。
实现方式2:间接指示感知目标的位置信息
作为一种实现方式,第一信息可以包括第三通信设备的相关信息,第三通信设备的相关信息用于第一通信设备确定感知目标的位置信息。或者说,第三通信设备的相关信息可以用于第一通信设备确定用于发送或接收感知信号的波束。在一些实施例中,第三通信设备也可以称为第三方设备、标签(label)设备等,例如,第三通信设备可以是第三方UE、label UE等。
需要说明的是,第三通信设备并不是感知信号的发送端或接收端,第三通信设备在感知过程中类似于一个标签,能够简化某些流程。
在一些实施例中,第三通信设备可以是感知目标附近的通信设备。例如,第三通信设备可以是和感知目标之间的距离小于某一阈值的通信设备,比如小于500米、小于300米等。
在一些实施例中,第三通信设备可以是感知目标携带的通信设备。例如,感知目标为汽车时,第三通信设备例如可以是汽车中的车载终端等。
本申请实施例对第三通信设备的相关信息的具体内容不做限定,只要其能够用于第一通信设备确定感知目标的位置信息即可。示例性地,第三通信设备的相关信息可以包括以下中的一种或多种:第三通信设备与第一通信设备之间的通信链路对应的波束指示信息,以及第三通信设备的标识信息。
作为一个示例,第三通信设备的相关信息可以包括第三通信设备与第一通信设备之间的通信链路对应的波束指示信息。以第三通信设备和第一通信设备均为终端设备为例,第三通信设备的相关信息例如可以包括两个终端设备之间侧行链路上的波束指示信息(如,TCI状态信息)。如此一来,第一通信设备可以根据第三通信设备与第一通信设备之间的通信链路对应的波束指示信息,使用该波束指示信息对应的波束发送或接收感知信号,以便对准感知目标。
作为另一个示例,第三通信设备的相关信息可以包括第三通信设备的ID信息。第一通信设备可以基于第三通信设备的ID信息,发现第三通信设备或者与第三通信设备建立通信链路,进而基于测量自行估计用于发送或接收感知信号的波束。以第三通信设备和第一通信设备均为终端设备为例,第一通信设备可以基于第三通信设备的ID信息,通过侧行发现或者通过与第三通信设备建立侧行链路(如,单播侧行链路),进而基于测量自行估计用于发送或接收感知信号的波束。
作为又一个示例,第三通信设备的相关信息可以包括第三通信设备与第一通信设备之间的通信链路对应的波束指示信息,以及第三通信设备的ID信息。
在一些实施例中,第三通信设备的相关信息可以是网络侧向第一通信设备配置的。
在一些实施例中,第三通信设备的相关信息可以是第二通信设备向第一通信设备配置的。
第一通信设备利用第三通信设备的相关信息确定感知目标的位置信息,有助于第一通信设备更好地对准感知目标,以便感知信号更好地冲向感知目标。
