Description

频域资源的切换方法、设备及计算机可读存储介质 技术领域
本申请涉及无线通信技术领域,具体而言,本申请涉及一种频域资源的切换方法、设备及计算机可读存储介质。
背景技术
新一代的AR(Augmented Reality,增强现实)/VR(Virtual Reality,虚拟现实),车车通信等新型互联网应用的不断涌现对于无线通信技术提出了更高的要求,驱使无线通信技术的不断演进以满足应用的需求。
当下,蜂窝移动通信技术正在处于新一代技术的演进阶段。新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。由于不同的业务类型对于无线通信技术有不同的要求,如eMBB(Enhanced Mobile Broadband,增强移动宽带)业务类型主要的要求侧重在大带宽、高速率等方面;URLLC(Ultra Reliable Low Latency Communication,高可靠和低延迟通信)业务类型主要的要求侧重在较高的可靠性以及低的时延方面;mMTC(massive Machine Type Communication,大规模机器类型通信)业务类型主要的要求侧重在大的连接数方面。因此新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
在无线通信系统中,低频的频域资源的传输性能比较好,已经广泛应用于无线通信技术中。然而由于业务的需求,低频的频域资源已经无法满足要求。在较高频率的资源上,由于频域资源比较丰富,可以提供较高频率的工作带宽,在高频上部署无线通信系统是一个重点的研究方向。在新一代的通信系统中,一个载波可能占用的带宽会比较大,比如100MHz(Mega Hertz,兆赫),在这种情况下,可以通过引入在一个带宽比较大的载波上划分成多个带宽部分(Bandwidth Part,BWP)来节省终端的电量消耗,比如一个载波的带宽是80MHz,里面包含了4个带宽部分,每 个带宽部分的带宽是20MHz。
在目前的设计中,终端可以有多个BWP的配置,但是终端同时只能在一个BWP(active BWP,激活的BWP)上进行数据的交互,即只有一个BWP处于工作状态。当在某些情况下,终端需要切换工作的BWP时,可以通过MAC CE(Medium access control Control Element,介质访问控制的控制单元)或是物理层信令通知终端进行active BWP的切换。
在现有的BWP切换机制中,当使用基于物理层信令进行active BWP的切换时,基站需要在调度指令中相应的信息域上指示BWP的切换,并且DL BWP(Downlink BWP,上行链路的BWP)和UL BWP(Uplink BWP,下行链路的BWP)是独立切换的。然而,在有些通信场景下,比如NTN(Non Terrestrial Network,非地面网络)通信场景,为了保证数据传输的可靠性,会通过多个业务波束来提供一个较大区域内的业务服务,而波束的切换是非常动态的,并且可能会出现用户切换BWP后,在一定的时间内并没有新的业务波束来服务用户的情况。因此,为了更好的满足通信需求,现有的频域资源切换方式有待改进。
发明内容

具体实施方式
下面详细描述本申请的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,仅用于解释本申请,而不能解释为对本发明的限制。
本技术领域技术人员可以理解,除非特意声明,这里使用的单数形式“一”、“一个”、“所述”和“该”也可包括复数形式。应该进一步理解的是,本申请的说明书中使用的措辞“包括”是指存在所述特征、整数、步骤、操作、元件和/或组件,但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组件和/或它们的组。应该理解,当我们称元件被“连接”或“耦接”到另一元件时,它可以直接连接或耦接到其他元件,或者也可以存在中间元件。此外,这里使用的“连接”或“耦接”可以包括无线连接或无线耦接。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
除非另外定义,本申请实施例使用的所有术语(包括技术术语和科学术语),具有与本申请所属领域中的普通技术人员的一般理解相同的意义。这里所使用的“用户设备”、“终端”、“终端设备”既包括无线信号接收器的设备,其仅具备无发射能力的无线信号接收器的设备,又包括接收和发射硬件的设备,其具有能够在双向通信链路上,进行双向通信的接收和发射硬件的设备。这种设备可以包括:蜂窝或其他通信设备,其具有单线路显示器或多线路显示器或没有多线路显示器的蜂窝或其他通信设备;PCS(Personal Communications Service,个人通信系统),其可以组合语音、数据处理、传真和/或数据通信能力;PDA(Personal Digital Assistant,个人数字助理),其可以包括射频接收器、寻呼机、互联网/内联网访问、网络浏览器、记事本、日历和/或GPS(Global Positioning System,全球定位系统)接收器;常规膝上型和/或掌上型计算机或其他设备,其具有和/ 或包括射频接收器的常规膝上型和/或掌上型计算机或其他设备。这里所使用的“终端”、“终端设备”、“用户设备”可以是便携式、可运输、安装在交通工具(航空、海运和/或陆地)中的,或者适合于和/或配置为在本地运行,和/或以分布形式,运行在地球和/或空间的任何其他位置运行。这里所使用的“终端”、“终端设备”、“用户设备”还可以是通信终端、上网终端、音乐/视频播放终端,例如可以是PDA、MID(Mobile Internet Device,移动互联网设备)和/或具有音乐/视频播放功能的移动电话,也可以是智能电视、机顶盒等设备。
为了满足多种新型互联网应用的通信需求,无线通信技术一直在不断演进。不同的应用场景、不同的业务对无线通信技术有着不同的要求,因此,新一代的无线通信系统需要灵活和可配置的设计来支持多种应用场景、多种业务类型的传输。
针对现有无线通信技术中所存在的上述问题,本申请实施例提供了一种频域资源的切换方法,基于该方法终端设备可以在其发生频域资源切换时,确定出为其服务的频域资源。本申请实施例所提供的方法适用于任意存在频域资源切换的通信场景中,尤其是通信系统中存在多服务波束的场景中,例如,在卫星通信系统中多服务波束的情况下,基于本申请实施例所提供的方案,终端设备可以便捷地确定其对应的频域资源。
本申请实施例所提供的方案可以根据实际需求,应用于各种通信场景中。可选的,本申请实施例的方案可以应用于卫星通信场景下。
在3GPP的技术发展中,卫星通信作为蜂窝通信系统的一种补充的方式已经有了大量的研究。5G NR(5Gth New Radio,第五代新空口系统)引入了非陆地网络(NTN,Non-terrestrial networks),所谓NTN,即5G卫星通信网,其网络具备小区半径大的特点,对于中/低轨卫星,其小区覆盖半径可以从100-1000千米,对于同步轨道卫星,其小区覆盖半径可以到几千米。
在无线通信技术的研究中,卫星通信被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继而进行的通信。卫星通信系统由卫星部分和地面部分组成。卫星通信的 特点是:通信范围大,只要在卫星发射的电波所覆盖的范围内,从任何两点之间都可进行通信;不易受陆地灾害的影响(可靠性高)。卫星通信作为目前地面的蜂窝通信系统的补充,可以有以下的好处:
延伸覆盖:对于目前蜂窝通信系统无法覆盖或是覆盖成本较高的地区,如海洋,沙漠,偏远山区等,可以通过卫星通信来解决通信的问题。
应急通信:在发生灾难如地震等的极端情况下导致蜂窝通信的基础设施不可用的条件下,使用卫星通信可以快速的建立通信连接。
提供行业应用:比如对于长距离传输的时延敏感业务,可以通过卫星通信的方式来降低业务传输的时延。
可以预见,在未来的无线通信系统中,卫星通信系统和陆地上的蜂窝通信系统会逐步的实现深度的融合,真正的实现万物智联。
在卫星通信的场景下,为了保证数据传输的可靠性,卫星通过多个波束来提供一个较大区域内的业务服务,同时由于卫星的高速移动性,波束的切换是非常动态的,并且可能会出现终端设备在切换BWP之后,在一定时间内没有新的业务波束来服务用户的情况,本申请实施例针对现有通信系统中存在的该情况的场景提供了一种频域资源的切换方法。
可以理解的是,本申请实施例所提供的方法可以适用于但不仅限于卫星通信系统中,且所适用的卫星通信系统可以是卫星采用透明转发方式(星上透明传输)的卫星通信系统,也可以是卫星采用非透明转发方式(星上信号再生)的卫星通信系统,还可以是双向连接模式的卫星通信系统。在卫星通信系统中,网络设备(如基站、接收点等)可以是部署在卫星上,也可以部署在地面站上,终端设备和网络设备之间的信号传输需要通过卫星中转。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。
图1示出了本申请实施例的通信方法的流程示意图,该方法由终端设备执行,如图1中所示,该方法可以包括以下步骤:
步骤S110:获取第一信息,第一信息用于终端设备确定进行频域资源切换的相关信息,相关信息包括切换时间和切换后的资源信息,切换后的资源信息包括切换后的服务波束标识和/或频域资源信息;
步骤S120:根据第一信息确定频域资源切换的相关信息。
其中,在通信系统中,波束包括上行波束和下行波束,本申请实施例中的服务波束标识(即波束ID)包括上行波束标识和下行波束标识中的至少一项,同样的,频域资源信息包括上行频域资源信息和下行频域资源信息中的至少一项。也就是说,本申请实施例中所提供的资源切换的切换方法,可以适用于上行频域资源的切换场景中,也可以适用于下行频域资源的切换场景中。
其中,基于第一信息可以确定出切换后的服务波束标识和频域资源信息中的至少一项,可以理解的是,该频域资源信息即为切换后的服务波束标识所对应的频域资源信息。
频域资源信息是指能够唯一标识频域资源的信息,可以包括但不限于频域资源的标识。本申请实施例中,服务波束标识对应的频域资源信息指的是为终端设备提供服务的、处于工作状态的频域资源信息。对于频域资源的资源粒度本申请实施例不做限定。
可选的,频域资源包括带宽部分即BWP,频域资源信息包括切换后激活的带宽部分的标识即BWP ID。
基于本申请提供的该切换方法,在发生频域资源切换的应用场景中,终端设备可以根据上述第一信息确定出切换时间、以及切换后的服务波束标识和/或频域资源信息,从而终端设备可以响应于该切换时间,基于确定的资源信息进行频域资源的切换,基于该方案,可以有效解决在发生频域资源切换时终端设备如何确定其为其服务的频域资源的问题。
可选的,本申请实施例提供的方案可以应用于卫星通信系统中,终端设备包括卫星通信系统中的终端设备。
对于终端设备获取第一信息的方式,本申请实施例不做限定。可以是通过协议预定义的方式获取,也可以是根据从网络设备获取到的第一消息的指示信息得到。其中,对于第一信息的具体名称本申请实施例不做限定。
需要说明的是,本申请实施例中所涉及的指示信息,可以是显示的指示信息,也可以是隐式的指示信息,即可以是能够直接确定对应的信息的指示,也可以能够间接的确定出对应信息的指示。例如,以上述第一信息的指示信息为例,该指示信息可以是第一信息,也可以是能够用于得到该第一信息的其他配置或指示信息。
本申请的可选实施例中,提供了两种实现频域资源切换的方式。一种是半静态切换方式(可以简称为方式1),另一种是动态切换方式(可以简称为方式2)。下面结合这两种方式,对两种方式所对应的多种可选实施例分别进行说明。
方式1:半静态切换方式
本申请的可选实施例中,上述第一信息包括第一映射关系,第一映射关系为时间信息和第二信息的对应关系,第二信息包括服务波束标识和/或频域资源信息;相应的,根据第一信息确定频域资源切换的相关信息,包括:
根据第一映射关系,确定频域资源切换的切换时间、以及切换时间对应的切换后的资源信息。
为了描述方便,将上述第一映射关系可以称为pattern(即模式),通过该pattern,终端设备可以知晓各时间信息与各时间信息所对应的切换后的资源信息的对应关系,如可以是各时间信息与各时间信息对应的服务波束标识的对应关系,也可以是各时间信息与各时间信息所对应的频域资源信息的对应关系,也可以是各时间信息、服务波束标识和频域资源信息中三者之间的对应关系。
其中,上述时间信息可以是时间点,也可以是时间段,可以是物理的时间信息(即绝对的时间信息,如一个时间信息可以是下午1点到2点),也可以是相对的时间信息,如可以是逻辑的时间信息,比如可以是通信系统的逻辑时间结构中的第n个时间单元(如帧、时隙等)到第m个时间单元。
终端设备获取到该pattern后,可以根据该pattern,可以知道各时间信息与对应的服务波束标识和/或频域资源信息之间的对应关系,即某个 时间信息所对应的服务波束标识和/或服务波束标识所使用的频域资源信息,从而可以根据该pattern,确定出切换时间,也可以切换后的资源信息。
作为一个示例,假设上述第一映射关系中包含绝对时间上第一时段(如下午1点到2点)与该时段对应的服务波束ID和该波束ID对应的激活的BWP ID的对应关系,以及第二时段(如下午2点到3点)与该时段对应的服务波束ID和该波束ID对应的激活的BWP ID的对应关系,则基于该映射关系,终端设备可以知道第一时段和第二时段各自所对应的资源信息,其中一个频域资源的切换时间为下午两点,在下午两点执行频域资源切换,在下午2点到3点的该时段基于该时段对应的服务波束ID、以及该波束对应的激活的BWP ID进行通信。
本申请的可选实施例中,上述第二信息可以包括服务波束标识和频域资源信息,也就是说,第一映射关系可以是各时间信息与各时间信息所对应的服务波束标识和频域资源信息的对应关系。
相应的是,上述根据第一映射关系,确定频域资源切换的切换时间、以及切换时间对应的切换后的资源信息,可以包括:
根据第一映射关系,确定切换时间,并将切换时间对应的时间信息所对应的服务波束标识和频域资源信息,确定为切换后的资源信息。
该可选方案中,终端设备可以基于第一映射关系直接确定出切换时间、切换后的服务波束ID和服务波束ID对应的频域资源信息。
本申请的可选实施例中,上述第二信息可以包括服务波束标识或频域资源信息,该方法还可以包括:
获取第二映射关系,第二映射关系为服务波束标识和频域资源信息的对应关系;
上述根据第一映射关系,确定频域资源切换的切换时间、以及切换时间对应的切换后的资源信息,包括:
根据第一映射关系,确定切换时间、以及切换时间对应的服务波束标识或频域资源信息;
根据所确定的服务波束标识和第二映射关系,确定服务波束标识对应的频域资源信息,或者,根据所确定的频域资源信息和第二映射关系,确 定频域资源信息对应的服务波束标识。
也就是说,上述第一映射关系可以是各时间信息与各时间信息各自对应的服务波束ID的对应关系,或者是各时间信息与各时间信息各自对应的频域资源信息(即服务于该终端设备的频域资源)的对应关系。此时,终端设备可以基于第一映射关系确定出切换时间和切换后的服务波束ID,或者是切换时间和切换后的频域资源信息,再基于第二映射关系进一步确定出频域资源信息或服务波束ID。
作为另一可选方式,上述第一映射关系也可以是各时间信息、各时间信息所对应的服务波束ID、各时间信息所对应的频域资源信息三者中的任意两者之间的对应关系,相应的,第二映射关系可以是该任意两者中的一个与三者中除该两者之外的另外一个的对应关系,终端设备根据第一映射关系确定出上述两者,在基于确定出的两者中的一个和第二映射关系,可以确定出另外一个。
本申请的可选实施例中,获取第一信息可以包括:
获取预定义的第一消息,或者,接收网络设备发送的第一消息的指示信息,根据该指示信息确定第一消息。
同样的,获取第二映射关系可以包括:
获取预定义的第二映射关系,或者,接收网络设备发送的第二映射关系的指示信息,根据该指示信息确定第二映射关系。
本申请的可选实施例中,接收网络设备发送的第一消息的指示信息,包括:
接收网络设备通过系统信息、高层信令或者物理层信令发送的第一消息的指示信息。
同样的,上述接收网络设备发送的第二映射关系的指示信息,可以包括:
接收网络设备通过系统信息、高层信令或者物理层信令发送的第一消息的指示信息。
也就是说,终端设备获取第一消息、第二映射关系等各信息的获取方式,可以是基于协议预先约定的获取得到,也可以是网络设备通过系统消 息、高层信息或者物理层信令告知终端设备,终端设备基于从网络设备接收到的指示信息获取相应的信息。例如,可以是基站通过RRC(Radio Resource Control,无线资源控制)信令、MAC CE等向终端设备对应的指示信息,同样,指示信息可以是显示的,也可以是隐式的。
本申请的可选实施例中,该方法还可以包括:
响应于根据第一信息确定不存在对应的资源信息,终端设备进入指定模式或进行候选服务波束的测量。
