请参考图1,其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括:终端设备10、接入网设备20和核心网设备30。
终端设备10可以指UE(User Equipment,用户设备)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、用户代理或用户装置。可选地,终端设备10还可以是蜂窝电话、无绳电话、SIP(Session Initiation Protocol,会话启动协议)电话、WLL(Wireless Local Loop,无线本地环路)站、PDA(Personal Digita1Assistant,个人数字处理)、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,5GS(5th Generation System,第五代移动通信系统)中的终端设备或者未来演进的PLMN(Pub1ic Land Mobi1e Network,公用陆地移动通信网络)中的终端设备等,本申请实施例对此并不限定。为方便描述,上面提到的设备统称为终端设备。终端设备10的数量通常为多个,每一个接入网设备20所管理的小区内可以分布一个或多个终端设备10。
接入网设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的设备。接入网设备20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,具备接入网设备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,“接入网设备”这一名称可能会变化。为方便描述,本申请实施例中,上述为终端设备10提供无线通信功能的装置统称为接入网设备。可选地,通过接入网设备20,终端设备10和核心网设备30之间可以建立通信关系。示例性地,在LTE(Long Term Evolution,长期演进)系统中,接入网设备20可以是EUTRAN(Evolved Universal Terrestrial Radio Access Network,演进的通用陆地无线网)或者EUTRAN中 的一个或者多个eNodeB;在5G NR系统中,接入网设备20可以是RAN(Radio Access Network,无线接入网)或者RAN中的一个或者多个gNB。在本申请实施例中,所述的“网络设备”除特别说明之外,是指接入网设备20,如基站。
核心网设备30是部署在核心网中的设备,核心网设备30的功能主要是提供用户连接、对用户的管理以及对业务完成承载,作为承载网络提供到外部网络的接口。例如,5G NR系统中的核心网设备可以包括AMF(Access and Mobility Management Function,接入和移动性管理功能)实体、UPF(User Plane Function,用户平面功能)实体和SMF(Session Management Function,会话管理功能)实体等设备。
在一些实施例中,接入网设备20与核心网设备30之间通过某种空口技术互相通信,例如5G NR系统中的NG接口。接入网设备20与终端设备10之间通过某种空口技术互相通信,例如Uu接口。
本申请实施例中的“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。本申请实施例描述的技术方案可以适用于LTE系统,也可以适用于5G NR系统,也可以适用于5G NR系统后续的演进系统,还可以适用于诸如NB-IoT(Narrow Band Internet of Things,窄带物联网)系统等其他通信系统,本申请对此不作限定。
在本申请实施例中,网络设备可以为小区提供服务,终端设备通过该小区使用的载波上的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
在介绍本申请技术方案之前,先对本申请涉及的一些背景技术知识进行介绍说明。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
1.终端能力信息上报
终端设备的无线通信能力信息是在初始接入主小区的时候通过RRC信令上报给基站,并进一步在核心网进行存储。在后续的通信过程中,终端设备的无线通信能力将保持恒定,且在移动过程中也无需进一步进行终端能力的重复上报,而是直接通过核心网下发给对应的基站进行使用。由于终端设备的无线通信能力信息相对较大,且通常情况下并不会随时发生改变,因此通过这种方式可以充分节省空口信令。
当终端设备的无线通信能力发生改变时,如要去更新其能力信息,终端设备需要从连接态重新回到空闲态并再次发起初始接入,来对其能力信息进行重新上报。
2.终端新形态的出现
随着终端技术的发展,现在逐步出现了一些区别于传统手机的终端形态,比如折叠屏手机、卷轴屏手机、伸缩屏手机等。如图2所示,终端设备在打开(非折叠)和关闭(折叠)状态下,其尺寸、形态都会发生较大改变。随着终端设备的状态发生改变,其实际的通信能力也会随之发生改变。
图2所示这类终端设备的特点是用户在使用中会随时在打开状态和关闭状态间进行切换,且打开相比关闭所具有的潜在通信能力也将更高。一个典型的例子是终端设备的MIMO(Multiple Input Multiple Output,多输入多输出)能力,它跟终端设备的天线性能密切相关。如图3所示,在打开状态下,终端设备的左右屏幕及边框距离很远,此时天线1和天线2的隔离度比较大,可以确保天线性能优秀。在关闭状态下,终端设备的左右屏幕及边框距离很近甚至是贴合的,此时天线1和天线2由于缺乏足够的隔离度导致相互影响,性能下降甚至使得这两个天线无法使用。
当前3GPP(3rd Generation Partnership Project,第三代合作伙伴计划)标准针对终端设备的无线通信能力是通过初始接入过程中的能力信息上报来完成的,当需要进行能力信息调整的时候需要回到空闲态并再次发起随机接入来更新能力信息。这种方式带来的问题是业务的不连续性,因为中间需要从连接态断开回到空闲态。另外一个问题是终端设备即使仅仅更新一个能力信息也需要将所有的能力信息进行重新上报,这带来了较高的复杂度与信令负担。
本申请技术方案将从改善终端业务连续性,同时考虑信令复杂度角度出发来优化终端设备的能力信息调整方法。下面,将通过几个实施例对本申请技术方案进行介绍说明。
请参考图4,其示出了本申请一个实施例提供的无线通信方法的流程图。该方法可以由终端设备执行。该方法可以包括如下步骤:
步骤410,处于连接态的终端设备向网络设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息。
相应地,网络设备接收处于连接态的终端设备发送的第一信息,该第一信息用于更新该终端设备的已有能力信息。
在本申请实施例中,第一信息是终端设备在处于连接态的情况下发送的。该连接态可以称为RRC连接态,即是指终端设备与网络设备之间具有连接的状态,如终端设备与接入网设备之间具有RRC连接的状态。连接态也可以称为RRC_CONNECTED状态,或者RRC连接态,或者CONNECTED状态,本申请对此不作限定。在连接态下,终端设备和接入网设备之间存在RRC连接,接入网设备和终端设备存在UE AS(Access Stratum,接入层)上下文,网络侧知道终端设备的位置是具体小区级别的,移动性是网络侧控制的移动性,终端设备和接入网设备之间可以传输单播数据。
在一些实施例中,处于连接态的终端设备在发生能力信息更新之后,向网络设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息。
当然,在一些其他实施例中,处于连接态的终端设备在发生能力信息更新之前,向网络设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息;后续,终端设备再对能力信息进行更新,使用新的能力信息。
在本申请实施例中,终端设备的能力信息用于指示该终端设备所支持或具备或使用的能力。在一些实施例中,终端设备的能力信息用于指示该终端设备所支持或具备或使用的通信能力,如无线通信能力。示例性地,上述通信能力包括但不限于以下至少之一:MIMO能力、射频能力、支持的天线数量、支持的传输流数量、带宽能力、支持的频段或频段组合、上行发送能力、下行接收能力,等等,本申请对此不作限定。
在本申请实施例中,终端设备的已有能力信息是指该终端设备的初始能力信息或者当前能力信息。第一信息用于对终端设备的初始能力信息或者当前能力信息进行更新。可选地,对终端设备的初始能力信息或者当前能力信息进行更新,得到更新后能力信息。更新后能力信息可以不同于初始能力信息或者当前能力信息,但本申请并不排除在一些实施例中,更新后能力信息与初始能力信息或者当前能力信息相同。上述初始能力信息是指终端设备在初始接入网络时,向网络设备上报的能力信息。当前能力信息是指终端设备在使用更新后能力信息之前使用的能力信息,或者当前正在使用的能力信息。
在本申请实施例中,能力信息可以包括能力项以及该能力项对应的能力值。例如,能力项包括但不限于以下至少之一:MIMO能力、射频能力、支持的天线数量、支持的传输流数量、带宽能力、支持的频段或频段组合、上行发送能力、下行接收能力等等。能力值是指该能力项对应的具体能力取值。例如,能力项为上行MIMO能力,其对应的能力值可以是2Layer(层数)、3Layer等。例如,能力项为下行MIMO能力,其对应的能力值可以是4Layer、6Layer等。例如,能力项为上行功率等级,其对应的能力值可以是PC2、PC3等。
在一些实施例中,第一信息用于指示该终端设备的新的能力信息。该新的能力信息可以包括终端设备的已有能力信息中未包含的能力项以及对应的能力值,也可以包括终端设备的已有能力信息中已包含的能力项以及对应的能力值(如更新后能力值)。
在一些实施例中,第一信息所指示的第一能力信息,用于替换已有能力信息。在一些实施例中,该新的能力信息可以是对已有能力信息的替换,例如已有能力信息包括能力项A和能力项B,其中能力项A对应的能力值为a1,能力项B对应的能力值为b1,新的能力信息可以包括能力项A且对应的能力值为a2,a2和a1不同,那么该新的能力信息用于将能力项A的能力值由a1替换成a2。
在一些实施例中,第一信息所指示的第二能力信息,用于在已有能力信息的基础上,增加第二能力信息。在一些实施例中,该新的能力信息也可以是已有能力信息中并不包含的能力信息,例如已有能力信息包括能力项A和能力项B,其中能力项A对应的能力值为a1,能力项B对应的能力值为b1,新的能力信息可以包括能力项C且对应的能力值为c1,能力项C是不同于能力项A和B的另一种能力项,那么该新的能力信息用于在已有能力信息的基础上,进一步增加能力项C且其对应的能力值为c1。
在一些实施例中,第一信息所指示的第一能力信息,用于替换已有能力信息;并且,第一信息所指示的第二能力信息,用于在已有能力信息的基础上,增加第二能力信息。也即,第一信息可以同时指示用于替换已有能力信息的第一能力信息,以及用于在已有能力信息的基础上增加的第二能力信息。
在一些实施例中,网络设备包括以下至少之一:接入网设备、核心网网元。其中,该接入网设备可以是终端设备所处服务小区的接入网设备。该核心网网元可以是核心网中负责存储终端能力信息的网元。
在一些实施例中,处于连接态的终端设备向接入网设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息。在本申请实施例中,对终端设备向接入网设备发送第一信息所使用的信令类型不作限定,例如RRC信令、MAC信令、UCI信令等信令中的任意一种。
在一些实施例中,处于连接态的终端设备向核心网网元发送第一信息,该第一信息用于更新该终端设备的已有能力信息。在本申请实施例中,对终端设备向核心网网元发送第一信息所使用的信令类型不作限 定,例如NAS(Non-Access Stratum,非接入层)信令或其他信令。
在一些实施例中,处于连接态的终端设备向接入网设备发送第一信息,接入网设备向核心网网元发送该第一信息,该第一信息用于更新该终端设备的已有能力信息。
在一些实施例中,处于连接态的终端设备向接入网设备和核心网网元分别发送第一信息,该第一信息用于更新该终端设备的已有能力信息。
另外,本申请实施例中所述的A向B发送信息,可以是指基于A和B之间建立的直接通信连接或链路,由A直接向B发送信息,也可以是指A和B之间并没有直接通信连接或链路,经过A和B之间的一个或多个设备或网元的中转转发,实现信息从A发送到B。
本申请实施例提供的技术方案,通过处于连接态的终端设备向网络设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息,实现了终端设备在保持连接态的情况下对自身能力信息进行更新,并且将新的能力信息上报给网络,从而无需终端设备退出连接态进行能力更新,提升了终端设备的业务连续性。
下面,对第一信息所包括的内容进行介绍说明。本申请提供了如下几种不同的方式,实现通过第一信息来更新终端设备的能力信息。
方式1
第一信息包括:能力项的标识信息和能力值。
其中,能力项的标识信息用于指示该能力项。不同的能力项具有不同的标识信息,通过该标识信息可以区分不同的能力项。
在一些实施例中,第一信息中包括的能力项,是已有能力信息中包含的能力项,此时第一信息包括的该能力项的能力值,可以是该能力项对应的更新后能力值。以上行MIMO能力为例,上行MIMO能力的初始能力值或当前能力值为2Layer(层数),更新后能力值为3Layer。
在一些实施例中,第一信息中包括的能力项,是已有能力信息中未包含的能力项,从而实现对新的能力项及其对应能力值的上报。
在一些实施例中,第一信息包括:一个能力项的标识信息和能力值。即第一信息仅上报一个能力项的能力信息。例如,上行MIMO能力发生更新,从2Layer变为3Layer,则第一信息包括:上行MIMO能力的标识信息和能力值,该上行MIMO能力的能力值为3Layer。
在一些实施例中,第一信息包括:多个能力项分别对应的标识信息和能力值。即第一信息可以同时上报多个能力项的能力信息。例如,上行MIMO能力和下行MIMO能力发生更新,上行MIMO能力从2Layer变为3Layer,下行MIMO能力从4Layer变为6Layer,则第一信息包括:上行MIMO能力的标识信息和能力值,以及下行MIMO能力的标识信息和能力值,该上行MIMO能力的能力值为3Layer,该下行MIMO能力的能力值为6Layer。
在一个示例中,终端设备的上行MIMO能力的初始能力值为2Layer。当终端设备的形态发生变化后,可选择上报新的上行MIMO能力,比如上报上行MIMO能力信息为3Layer。网络设备(如基站)收到终端设备的新上行MIMO能力信息为3Layer后,网络设备将用该3Layer能力替换此前的2Layer能力,并基于此能力对终端设备进行调度。当终端设备的形态再次发生变化,导致其上行MIMO能力从当前的3Layer变更为2Layer时,终端设备可选择上报新的上行MIMO能力,比如上报上行MIMO能力信息为2Layer。网络设备收到终端设备的新上行MIMO能力信息为2Layer后,网络设备将用该2Layer能力替换此前的3Layer能力,并基于此能力对终端设备进行调度。
对于该方式1,终端设备向网络设备发送的第一信息中,包括能力项的标识信息和能力值,当有某个或某些能力项需要更新或增加时,直接将对应的能力值进行上报,具有较高的灵活性。
方式2
第一信息包括:能力项组合对应的能力值信息;其中,能力项组合中包括n个能力项,能力值信息包括n个能力项分别对应的能力值,n为正整数。
在这种方式中,第一信息包括n个能力项分别对应的能力值,不需要包含该n个能力项分别对应的标识信息。在一些实施例中,上述能力项组合是预定义的,终端设备和网络设备之间提前预定义好能力项组合,这样就不用在第一信息中包含能力项对应的标识信息,仅需包含能力项对应的能力值就行。
在一些实施例中,能力项组合中可以仅包括一个能力项,或者包括多个能力项。
另外,由于能力项组合是预定义的,终端设备有可能对该能力项组合中包含的所有能力项的能力值都进行更新,也有可能仅对其中一部分能力项的能力值进行更新。但是,不论是全部更新还是部分更新,第一信息中需要包括能力项组合中包含的所有能力项(即全部n个能力项)分别对应的能力值。也就是说,对于能力项组合中包含的任意一个能力项,如果该能力项的能力值发生更新,则第一信息中包含该能力项 对应的更新后能力值;如果该能力项的能力值未发生更新,则第一信息中包含该能力项对应的已有能力值(如初始能力值或当前能力值)。
例如,能力项组合包括上行MIMO能力、下行MIMO能力和上行功率等级这3个能力项,假设上行MIMO能力从2Layer变为3Layer,下行MIMO能力从4Layer变为6Layer,上行功率等级保持PC2不变,那么第一信息包括:上行MIMO能力对应的能力值“3Layer”、下行MIMO能力对应的能力值“6Layer”、上行功率等级对应的能力值“PC2”。
在一些实施例中,第一信息包括:一个能力项组合对应的能力值信息,一个能力项组合中包括一个或多个能力项。即,第一信息包括一个能力项组合包含的各个能力项分别对应的能力值。例如,预定义一个能力项组合包括上行MIMO能力、下行MIMO能力和上行功率等级这3个能力项,假设上行MIMO能力从2Layer变为3Layer,下行MIMO能力保持4Layer不变,上行功率等级从PC2变为PC3,那么第一信息包括:上行MIMO能力对应的能力值“3Layer”、下行MIMO能力对应的能力值“4Layer”、上行功率等级对应的能力值“PC3”。
在一些实施例中,第一信息包括:多个能力项组合分别对应的能力值信息,每个能力项组合中包括一个或多个能力项,且任意两个不同能力项组合中包含的能力项数量可以相同也可以不同,任意两个不同能力项组合中包括至少一个不同的能力项,每个能力项组合对应的能力值信息包括该能力项组合包含的各个能力项分别对应的能力值。例如,预定义两个能力项组合,记为能力项组合1和能力项组合2,其中能力项组合1包括能力项A、能力项B和能力项C这3个能力项,能力项组合2包括能力项D和能力项E这2个能力项,其中,能力项A、B、C、D、E是5种不同的能力项。假设能力项A从能力值a1变为能力值a2,能力项B保持能力值b1不变,能力项C保持能力项c1不变,能力项D从能力值d1变为能力值d2,能力项E从能力值e1变为能力值e2,那么第一信息包括能力项组合1对应的能力值信息和能力项组合2对应的能力值信息,其中能力项组合1对应的能力值信息包括能力项A对应的能力值a2、能力项B对应的能力值b1和能力项C对应的能力值c1,能力项组合2对应的能力值信息包括能力项D对应的能力值d2和能力项E对应的能力值e2。
对于该方式2,终端设备向网络设备发送的第一信息中,包括预定义的能力项组合包含的n个能力项分别对应的能力值,实现了一个或多个能力项的能力值指示,且不需要在第一信息中包括能力项的标识信息,有助于节省第一信息的比特开销。当然,这种方式由于能力项组合是预定义的,不同于单个能力项的能力值指示,在这种组合上报方式中,组合内的多个能力项总是同时出现,并可分别取值。
在一个示例中,预定义一个能力项组合,包括上行MIMO能力、下行MIMO能力和上行功率等级这3个能力项。其中,上行MIMO能力对应的能力值取值提供了2Layer、3Layer和空共3种选项,可选择其中任意一种;下行MIMO能力对应的能力值取值提供了4Layer、6Layer和空共3种选项,可选择其中任意一种;上行功率等级对应的能力值取值提供了PC2、PC3和空共3种选项,可选择其中任意一种。终端设备在上述各个能力项对应的能力值取值中,可以任意选择进行组合,比如上行MIMO能力对应的能力值为2Layer、下行MIMO能力对应的能力值为6Layer、上行功率等级对应的能力值为PC3等。当对于某个能力项对应的能力值选择“空”时,意味着终端设备对于该能力项的能力值保持不变。当然对于能力值保持不变的情况也可以选择跟此前相同的取值。示例性的,终端设备的初始能力信息包括上行MIMO能力对应的初始能力值为2Layer,下行MIMO能力对应的初始能力值为4Layer,上行功率等级对应的初始能力值为PC2。终端设备对初始能力信息进行更新,更新后能力信息包括上行MIMO能力对应的更新后能力值为3Layer,下行MIMO能力对应的更新后能力值为6Layer,上行功率等级对应更新后能力值仍然为PC2,与初始能力值一致。终端设备发送第一信息,该第一信息包括:上行MIMO能力对应的能力值“3Layer”、下行MIMO能力对应的能力值“6Layer”、上行功率等级对应的能力值“空”;或者,该第一信息包括:上行MIMO能力对应的能力值“3Layer”、下行MIMO能力对应的能力值“6Layer”、上行功率等级对应的能力值“PC2”。
方式3
第一信息包括:能力项组合对应的能力值指示信息;其中,能力项组合中包括n个能力项,能力值指示信息包括n个能力项分别对应的能力值指示码字,能力值指示码字用于指示能力值,n为正整数。
在这种方式中,第一信息包括n个能力项分别对应的能力值指示码字,能力值指示码字用于指示能力值。方式3具有方式2的优点,进一步地,方式3相比于方式2在第一信息的比特开销上可以进一步节省,不需要直接携带能力值,而是携带能力值指示码字。
在一些实施例中,上述能力项组合是预定义的,终端设备和网络设备之间提前预定义好能力项组合,这样就不用在第一信息中包含能力项对应的标识信息,仅需包含能力项对应的能力值指示码字就行。
在一些实施例中,能力项组合中可以仅包括一个能力项,或者包括多个能力项。
另外,由于能力项组合是预定义的,终端设备有可能对该能力项组合中包含的所有能力项的能力值都 进行更新,也有可能仅对其中一部分能力项的能力值进行更新。但是,不论是全部更新还是部分更新,第一信息中需要包括能力项组合中包含的所有能力项(即全部n个能力项)分别对应的能力值指示码字。也就是说,对于能力项组合中包含的任意一个能力项,如果该能力项的能力值发生更新,则第一信息中包含该能力项对应的更新后能力值对应的能力值指示码字;如果该能力项的能力值未发生更新,则第一信息中包含该能力项对应的已有能力值(如初始能力值或当前能力值)对应的能力值指示码字。
在一个示例中,预定义一个能力项组合,包括上行MIMO能力、下行MIMO能力和上行功率等级这3个能力项。其中,上行MIMO能力对应的能力值取值提供了2Layer、3Layer和空共3种选项,这3种选项对应的能力值指示码字分别为00、01和10,可选择其中任意一种;下行MIMO能力对应的能力值取值提供了4Layer、6Layer和空共3种选项,这3种选项对应的能力值指示码字分别为00、01和10,可选择其中任意一种;上行功率等级对应的能力值取值提供了PC2、PC3和空共3种选项,这3种选项对应的能力值指示码字分别为00、01和10,可选择其中任意一种。终端设备在上述各个能力项对应的能力值取值中,可以任意选择进行组合,比如上行MIMO能力对应的能力值为2Layer、下行MIMO能力对应的能力值为6Layer、上行功率等级对应的能力值为PC3等。当对于某个能力项对应的能力值选择“空”时,意味着终端设备对于该能力项的能力值保持不变。当然对于能力值保持不变的情况也可以选择跟此前相同的取值。示例性的,终端设备的初始能力信息包括上行MIMO能力对应的初始能力值为2Layer,下行MIMO能力对应的初始能力值为4Layer,上行功率等级对应的初始能力值为PC2。终端设备对初始能力信息进行更新,更新后能力信息包括上行MIMO能力对应的更新后能力值为3Layer,下行MIMO能力对应的更新后能力值为6Layer,上行功率等级对应更新后能力值仍然为PC2,与初始能力值一致。终端设备发送第一信息,该第一信息包括:上行MIMO能力对应的能力值指示码字“01”、下行MIMO能力对应的能力值“01”、上行功率等级对应的能力值“10”,如第一信息包含的能力值指示信息共6个比特,为“010110”;或者,该第一信息包括:上行MIMO能力对应的能力值“01”、下行MIMO能力对应的能力值“01”、上行功率等级对应的能力值“00”,如第一信息包含的能力值指示信息共6个比特,为“010100”。
对于每一个能力项来说,其对应的能力值指示码字的比特数,可以由该能力项对应的能力值的可选择数量确定。假设能力值指示码字的比特数为k,其最多能够指示2 k(即2的k次方)种能力值,k为正整数。例如,1个比特最多可以指示2种能力值,2个比特最多可以指示4种能力值,3个比特最多可以指示8种能力值,以此类推。对于每一个能力项来说,如果该能力项对应的能力值的可选择数量为1或2,那么该能力项对应的能力值指示码字的比特数为1即可;如果该能力项对应的能力值的可选择数量大于2且小于或等于4,那么该能力项对应的能力值指示码字的比特数为2即可;如果该能力项对应的能力值的可选择数量大于4且小于或等于8,那么该能力项对应的能力值指示码字的比特数为3即可,以此类推。
在一些实施例中,第一信息包括:一个能力项组合对应的能力值指示信息,一个能力项组合中包括一个或多个能力项。即,第一信息包括一个能力项组合包含的各个能力项分别对应的能力值指示码字。例如,预定义一个能力项组合包括上行MIMO能力、下行MIMO能力和上行功率等级这3个能力项,假设上行MIMO能力从2Layer变为3Layer,下行MIMO能力保持4Layer不变,上行功率等级从PC2变为PC3,那么第一信息包括:上行MIMO能力对应的能力值3Layer对应的能力值指示码字、下行MIMO能力对应的能力值4Layer对应的能力值指示码字、上行功率等级对应的能力值PC3对应的能力值指示码字。
在一些实施例中,第一信息包括:多个能力项组合分别对应的能力值指示信息,每个能力项组合中包括一个或多个能力项,且任意两个不同能力项组合中包含的能力项数量可以相同也可以不同,任意两个不同能力项组合中包括至少一个不同的能力项,每个能力项组合对应的能力值指示信息包括该能力项组合包含的各个能力项分别对应的能力值指示码字。例如,预定义两个能力项组合,记为能力项组合1和能力项组合2,其中能力项组合1包括能力项A、能力项B和能力项C这3个能力项,能力项组合2包括能力项D和能力项E这2个能力项,其中,能力项A、B、C、D、E是5种不同的能力项。假设能力项A从能力值a1变为能力值a2,能力项B保持能力值b1不变,能力项C保持能力项c1不变,能力项D从能力值d1变为能力值d2,能力项E从能力值e1变为能力值e2,那么第一信息包括能力项组合1对应的能力值指示信息和能力项组合2对应的能力值指示信息,其中能力项组合1对应的能力值指示信息包括能力项A对应的能力值a2的能力值指示码字、能力项B对应的能力值b1的能力值指示码字和能力项C对应的能力值c1的能力值指示码字,能力项组合2对应的能力值指示信息包括能力项D对应的能力值d2的能力值指示码字和能力项E对应的能力值e2的能力值指示码字。
对于该方式3,其除了具有方式2的优点以外,相比于方式2在第一信息的比特开销上可以进一步节省,因为不需要在第一信息中直接携带能力值,而是携带能力值指示码字,能力值指示码字所需的比特数,会比能力值所需的比特数要少,从而达到进一步节省信令比特开销的目的。
在一些实施例中,对于上述方式2和方式3,能力项组合由标准规定,或网络定义并指示给终端设备,或终端设备定义并指示给网络。
在一些实施例中,对于上述方式2和方式3,能力项组合由终端设备定义并指示给网络。终端设备从能力项集合中确定n个能力项,得到能力项组合;其中,能力项集合中包括多个候选的能力项;终端设备向网络发送能力项组合的指示信息。该能力项组合的指示信息用于指示能力项组合中包含的n个能力项,例如该能力项组合的指示信息可以包括能力项组合中包含的n个能力项分别对应的标识信息。在一些实施例中,能力项组合的指示信息采用以下信令中的至少一种发送:RRC信令、NAS信令。通过这种方式,终端设备自主组合要更新的能力项得到能力项组合,终端设备需要将定义的能力项组合所含能力项上报给网络设备,在后续的通信过程中进一步指示组合内的能力值。相比于能力项组合由标准规定,这种终端设备定义并指示给网络的方式,给了终端设备更多的自由度来决定哪些能力项的能力值可以变更。
为了实现终端设备与网络设备对终端自主定义的能力项组合中所含信息的统一认识,可采用标准规定或网络设备对可调整的能力项进行统一定义的方式,比如标准规定或网络设备定义了一个能力项集合,该能力项集合中包括10种可选择调整的能力项,以及每种能力项的可选择能力值。终端设备进一步从该能力项集合中选择出适用的n种能力项,并将其组合为能力项组合,进行指示。能力项组合中包含的能力项数量,可以小于或等于能力项集合中包含的能力项数量。上述能力项组合的指示信息通过RRC信令上报给接入网设备,如需上报给核心网网元则经过NAS信令传输。终端设备在通信过程中通过RRC信令或MAC信令或UCI信令指示能力项组合中的能力值。
例如,终端设备自主定义的能力项组合如下表1所示:
表1
能力项组合包含的能力项 上行MIMO能力 下行MIMO能力 上行功率等级
可选择能力值 2Layer或3Layer 4Layer或6Layer PC2或PC3
方式4
第一信息包括:能力信息指示码字,能力信息指示码字用于指示能力信息组合,能力信息组合包括m个能力项分别对应的能力值,m为正整数。
为了降低能力信息更新的复杂度,可将终端设备的几个能力项(比如上行MIMO能力、下行MIMO能力、上行功率等级等)定义为一个组合,针对该组合定义几个状态,比如高能力组合状态、低能力组合状态等。这里为了描述的简单,采用了高、低能力组合的说法,实际可以是组合内某几个能力为高能力而某几个能力为低能力,此时可用能力组合状态1、能力组合状态2等说法,具体取决于需求。在后续通信过程中,终端设备可以选择指示其中的一个状态组合(也即上文所述的“能力信息组合”)来完成对已有能力信息(如初始能力信息或当前能力信息)的整体替换。
示例性地,预先定义好若干个不同的能力信息组合,以及各个能力信息组合分别对应的能力信息指示码字。例如如下表2所示:
表2
Figure PCTCN2022088847-appb-000001
假设终端设备的已有能力信息(如初始能力信息或当前能力信息)为能力信息组合1,更新后能力信息为能力信息组合2,由上述表2可知,能力信息组合2对应的能力信息指示码字为“001”,那么终端设备向网络设备发送的第一信息包括能力信息指示码字“001”,用于指示终端设备的更新后能力信息为上行MIMO能力为3Layer、下行MIMO能力为4Layer且上行功率等级为PC2。
能力信息指示码字所需的比特数,可以由能力信息组合的可选择数量确定。假设能力信息指示码字的比特数为p,其最多能够指示2 p(即2的p次方)种能力信息组合,p为正整数。例如,1个比特最多可以指示2种能力信息组合,2个比特最多可以指示4种能力信息组合,3个比特最多可以指示8种能力信息组合,以此类推。如果能力信息组合的可选择数量为1或2,那么能力信息指示码字的比特数为1即可;如果能力信息组合的可选择数量大于2且小于或等于4,那么能力信息指示码字的比特数为2即可;如果能力信息组合的可选择数量大于4且小于或等于8,那么能力信息指示码字的比特数为3即可,以此类推。
在一些实施例中,对于上述方式4,能力信息组合由标准规定,或网络定义并指示给终端设备,或终端设备定义并指示给网络。例如,预定义能力信息组合1和能力信息组合2,其中,能力信息组合1包括上行MIMO能力为2Layer,下行MIMO能力为4Layer,上行功率等级为PC3;能力信息组合2包括上行MIMO能力为3Layer,下行MIMO能力为6Layer,上行功率等级为PC2。终端设备在上述能力信息组合1和2中选择其中一个进行上报,或者采用激活能力信息组合1或激活能力信息组合2的方式来上报。例如:预定义能力信息组合(上报“1”),或者预定义能力信息组合1(上报“激活”),能力信息组合2(上报“不激活”或者不上报)。
在一些实施例中,对于上述方式4,能力信息组合由终端设备定义并指示给网络。终端设备向网络发送能力定义信息,该能力定义信息用于定义一个或多个能力信息组合。当采用终端设备自主定义能力信息组合的方式时,终端设备需要将定义的能力信息组合上报给网络,并在后续的通信过程中进一步指示哪个能力信息组合起作用或被使用或被激活。相比于能力信息组合由标准规定,通过终端设备自主定义能力信息组合的方式,给了终端设备更多的自由度来决定哪些能力信息可以变更。
另外,为了实现终端设备与网络设备对终端自主定义的能力信息组合中所含信息的统一认识,可采用标准规定或网络设备对可调整的能力项和/或能力值进行统一定义的方式,比如标准规定或网络设备定义了一个能力项集合,该能力项集合中包括10种可选择调整的能力项,以及每种能力项的可选择能力值。终端设备进一步从该能力项集合中选择出适用的一种或多种能力项,并确定相应的能力值,得到一个或多个预定义的能力信息组合,然后指示给网络。能力信息组合中包含的能力项数量,可以小于或等于能力项集合中包含的能力项数量。上述能力定义信息通过RRC信令上报给接入网设备,如需上报给核心网网元则经过NAS信令传输。终端设备在通信过程中通过RRC信令或MAC信令或UCI信令指示起作用或被使用或被激活的能力信息组合。
在一些实施例中,能力定义信息包括:第一指示信息和至少一个第二指示信息;其中,第一指示信息用于指示一种能力项组合,每个第二指示信息用于指示能力项组合中包含的各个能力项对应的一组能力值。
例如,终端设备自主定义能力项组合包含上行MIMO能力、下行MIMO能力和上行功率等级,进一步地,终端设备定义该能力项组合对应的一组能力值为{2Layer、4Layer、PC3}、另一组能力值为{3Layer、6Layer、PC2},对应关系如下表3所示:
表3
能力项组合 上行MIMO能力 下行MIMO能力 上行功率等级
第1组能力值 2Layer 4Layer PC3
第2组能力值 3Layer 6Layer PC2
在一些实施例中,能力定义信息包括:至少一个第三指示信息;其中,每个第三指示信息用于指示一种能力项组合以及该能力项组合中包含的各个能力项对应的一组能力值。
例如,终端设备自主定义能力信息组合1和能力信息组合2(不再单独定义能力项组合包含的能力项),能力信息组合1和能力信息组合2所含内容可以不同,终端设备可以通过2个不同的第三指示信息来指示该能力信息组合1和能力信息组合2,示例性如下表4所示。在这种方式下,终端设备可以直接上报能力信息组合1或能力信息组合2来更新能力信息,或先上报能力信息组合1和2的内容,然后再采用激活或去激活方式来实现新的能力信息替换已有能力信息。
表4
Figure PCTCN2022088847-appb-000002
上述表4示例所对应的方式,相比于表3示例所对应的方式,能力定义信息中定义的能力项组合和相应能力值会更加灵活一些。
对于该方式4,通过在第一信息中携带能力信息指示码字,来指示一组能力项分别对应的能力值,能够更加充分地节省第一信息所需的比特开销。例如,方式4和方式3相比,同样指示8中可能的能力信息组合,若采用方式3第一信息需要用6个比特,但采用方式4第一信息仅需3个比特即可。
下面,对终端设备上报初始能力信息进行介绍说明。如图5所示,终端设备发送第二信息,该第二信息用于指示终端设备的初始能力信息,该初始能力信息由核心网网元进行存储。
在一些实施例中,终端设备向接入网设备发送第二信息,该第二信息用于指示终端设备的初始能力信息,接入网设备存储该终端设备的初始能力信息;并且,接入网设备向核心网网元转发该第二信息,核心网网元也存储该终端设备的初始能力信息。
在一些实施例中,终端设备向接入网设备发送第二信息,该第二信息用于指示终端设备的初始能力信息,接入网设备存储该终端设备的初始能力信息;并且,终端设备向核心网网元发送该第二信息,核心网网元也存储该终端设备的初始能力信息。
初始能力信息由终端设备经接入网设备(如基站)传输到核心网,或者由终端设备不经过接入网设备(如基站)直接传输到核心网,并作为相对静态信息存储于核心网,作为该终端设备的基础能力信息使用。以终端设备为折叠屏终端为例,由于终端设备的绝大部分能力信息都不会因终端设备的折叠而改变,比如支持的频段或频段组合属于射频能力,并不会因天线能力的改变而改变,因此终端设备的能力信息更新不需要对所有的终端能力进行再次传输。
此外,由于终端设备的形态改变具有高频次、不固定的特点,因此需要确定一种终端形态或能力信息作为基础能力进行上报。以折叠屏终端为例:
假设终端设备在打开(也即非折叠状态)的情况下其上行发射能力为3个天线及对应的发射链路在同时工作,其下行接收能力为6个接收天线及对应的接收链路在同时工作,也即上行最大支持3流发射,下行最大支持6流接收。
假设终端设备在关闭(也即折叠状态)的情况下其上行发射能力为2个天线及对应的发射链路在同时工作,其下行接收能力为4个接收天线及对应的接收链路在同时工作,也即上行最大支持2流发射,下行最大支持4流接收。
对于该终端设备,其打开或关闭都是常用的工作状态,终端设备在初始能力信息上报的时候可以有下述几种处理方式:
方式1:初始能力信息包括终端设备支持的多个能力项分别对应的最低能力值;
也即,选取最低能力进行上报,比如上行2发、下行4收。
方式2:初始能力信息包括终端设备支持的多个能力项分别对应的最高能力值;
也即,选取最高能力进行上报,比如上行3发、下行6收。
方式3:初始能力信息包括终端设备支持的多个能力项分别对应的初始能力值,每个能力项对应的初始能力值从能力项对应的至少一个候选能力值中确定。
也即,选取一组初始能力值进行上报,例如上行2发且下行4收,或者上行2发且下行6收,或者上行3发且下行4收,或者上行3发且下行6收。
需要说明的是,上述关于折叠屏终端的示例中,仅以打开或关闭带来的多个能力变化都是同时增加或同时减少,而在其他的例子中会存在终端设备从一个状态变化到另外一个状态时有的能力是增加的,而有的能力是降低的,此时需要以一个状态为基础进行初始能力信息的上报。
上面方式1是一种保守的处理方式,也即无论终端设备在何种状态下,都不会低于其初始能力信息。因此接入网设备可以始终依据初始能力信息进行调度,而不用担心超过终端设备的能力上限。
上面方式2则是更加激进的处理方式,也即终端设备的最高能力。接入网设备在调度过程中需要判断终端设备当前的实际能力是否能达到这个初始能力信息,并进一步去对终端设备进行配置。
上面方式3则跟终端设备的使用状态有关,有的能力是高能力,有的能力是低能力。并且,接入网设备在调度过程中同样需要判断终端设备当前的实际能力是否能达到这个初始能力信息,并进一步去对终端设备进行配置。
终端设备完成初始能力信息上报后,其初始能力信息除了存储在核心网外,在服务小区的接入网设备(如基站)中也有该终端设备的初始能力信息,用于空口的无线资源配置。当终端设备的能力信息发生改变时(如终端设备的使用状态发生改变导致无线能力改变时),终端设备需要对其能力信息进行更新。
终端设备的能力信息更新可以包括如下两种方式,记为方式a和方式b。
如图6所示,方式a为仅在接入网设备(如基站)处更新。也就是说,对于该方式a,新的能力信息将仅用于接入网设备的调度更新,而不会在核心网进行存储。
如图7所示,方式b为在接入网设备(如基站)和核心网同时更新。也就是说,对于该方式b,新的能力信息既用于接入网设备的调度更新,且还会在核心网进行存储。
相比之下,仅在接入网设备处进行能力信息的变更将更加快速,且节约网络信令。
下面,对网络侧对终端能力信息更新行为的控制进行介绍说明。
在一些实施例中,处于连接态的终端设备在确定满足更新条件的情况下,向网络设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息。
在一些实施例中,上述更新条件包括以下至少之一:
时间约束条件,用于指示允许和/或不允许进行能力信息更新的时间;
内容约束条件,用于指示允许和/或不允许更新的能力项和/或能力值;
指标约束条件,用于指示允许和/或不允许进行能力信息更新的通信指标;
场景约束条件,用于指示允许和/或不允许进行能力信息更新的场景。
为了进一步降低复杂度,接入网设备可以采取措施限制终端能力更新。接入网设备对终端更新能力信息的行为的控制包括但不限于一下几个层面:更新的时间、更新的内容(能力项和/或能力值)、更新的指标条件、更新的场景。
在一些实施例中,时间约束条件基于第一定时器和/或第二定时器实现;其中,第一定时器用于规定允许进行能力信息更新的时间,第二定时器用于规定不允许进行能力信息更新的时间。
例如,第一定时器也可称为允许能力更新定时器,第二定时器也可称为阻止能力更新定时器。在一些实施例中,第一定时器和/或第二定时器可以由网络配置(如接入网设备配置),并指示给终端设备。在一些实施例中,当第一定时器工作时,允许终端设备进行能力更新操作;当第二定时器工作时,不允许终端设备进行能力更新操作。这两种定时器可以是周期性的,即每隔一定时间后激活一次,来周期性地阻止或允许终端设备进行能力更新。这两种定时器也可以是非周期性的,由网络(如接入网设备)根据需要来激活或去激活。在一些实施例中,上述两种定时器可以针对终端设备的发射能力和接收能力分别定义,也可以一起定义。
在一些实施例中,内容约束条件基于第一内容列表和/或第二内容列表实现;其中,第一内容列表用于定义允许更新的能力项和/或能力值,第二内容列表用于定义不允许更新的能力项和/或能力值。
例如,第一内容列表也可称为允许更新的能力列表,第二内容列表也可称为不允许更新的能力列表。在一些实施例中,第一内容列表和/或第二内容列表可以由网络配置(如接入网设备配置),并指示给终端设备。示例性地,接入网设备可以通过提供一个允许更新的能力列表(比如上行MIMO能力、下行MIMO能力、上行功率等级)来限制终端设备的能力更新,终端设备仅允许在这个列表里面选择做更新的能力项和/或能力值。接入网设备也可以通过提供一个不允许更新的能力列表来限制终端设备的能力更新,终端设备只能更新那些没有包含在这个列表里面的能力项和/或能力值。在一些实施例中,接入网设备可以周期性或非周期性的向小区内终端设备提供上述第一内容列表和/或第二内容列表。另外,上述第一内容列表和/或第二内容列表也可以是标准规定的。在一些实施例中,第一内容列表和/或第二内容列表可以分别对终端设备的发射能力和接收能力进行定义,也可以一起定义。
在一些实施例中,通信指标包括以下至少之一:吞吐量、信噪比、信号强度。在一些实施例中,网络(如接入网设备)可以配置指标约束条件来对终端能力更新进行控制。示例性地,接入网设备可配置一个吞吐量门限(或信噪比门限或信号强度门限),当吞吐量(或信噪比或信号强度)低于该门限时,终端设备不允许进行能力信息的更新或允许终端设备进行能力信息的更新。需要说明的是,这里的门限可以对于上行和下行分别配置,也可以上下行共用同一个门限。并且,这里的门限也可以仅针对终端设备的发射能力更新进行限制,也可以仅针对终端设备的接收能力更新进行限制,也可以同时对终端设备的发射能力和接收能力更新起作用。
在一些实施例中,不允许进行能力信息更新的场景包括以下至少之一:切换场景、高速移动场景。示例性地,网络(如接入网设备)可限定终端设备的能力更新只能在非切换场景或非高速移动场景等情况下进行更新。其中,切换场景是指终端设备执行小区切换流程的场景。高速移动场景是指终端设备正在进行高速移动的场景,例如终端设备的移动速度大于或等于速度阈值,该速度阈值可以由标准规定,或网络定义并指示给终端设备,或终端设备定义并指示给网络。
在一些实施例中,上述更新条件由标准规定,或网络定义并指示给终端设备,或终端设备定义并指示给网络。
通过设定更新条件,终端设备在确定满足更新条件的情况下才能进行能力更新,有助于避免执行一些不必要的能力信息更新流程,降低通信系统的复杂度。
在一些实施例中,处于连接态的终端设备向服务小区对应的接入网设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息。
在一些实施例中,处于连接态的终端设备在确定满足更新条件的情况下,向服务小区对应的接入网设备发送第一信息,该第一信息用于更新该终端设备的已有能力信息。
在一些实施例中,服务小区对应的接入网设备向至少一个邻小区对应的接入网设备指示该终端设备的能力信息。例如,服务小区对应的接入网设备向至少一个邻小区对应的接入网设备指示该终端设备的新的能力信息。
在前面提到,终端设备的能力信息更新可以只在接入网设备进行更新而不更新核心网存储的终端能力信息,也可以同时更新接入网设备和核心网侧存储的该终端能力信息。相比之下,只更新接入网设备存储的能力信息具有信令负担小、更新灵活的优点,但同时也具有终端新能力适用范围低的问题,特别是对于 一些终端能力更新不太频繁或处于小区边缘及切换等场景下的能力更新可以做进一步的优化。
一种方法是将终端设备的能力更新适用范围做进一步的扩大,也即终端设备的新的能力信息不仅适用于当前服务小区,也适用于一个邻近小区组,这个邻近小区组可以由当前服务小区的接入网设备确定。当终端设备向当前服务小区上报了新的能力信息之后,该新的能力信息将同时被用于替换在本服务小区接入网设备以及在邻近小区组内接入网设备的该终端能力信息。
通过上述方式,实现了将终端设备的新的能力信息在当前服务小区和一个或多个邻小区中进行同步更新,使得终端设备在从当前服务小区移动到邻小区之后,可以直接使用新的能力信息,而不必执行一遍能力信息更新的流程,有助于简化终端行为,节省终端电量。
下面,对终端设备发送第一信息的信令流程进行介绍说明。
终端设备的能力信息变更可以为终端设备主动发起的能力信息更新过程,也可以为网络侧(如接入网设备)查询的终端能力信息更新过程。为了跟不具备能力信息变更的终端设备进行区分,定义一个“终端能力信息变更”的能力信息。如终端设备具备“终端能力信息变更”的能力,则需将该能力上报给网络(如接入网设备)。
在一些实施例中,如图8所示,终端设备发送第三信息,该第三信息用于指示终端设备是否支持在连接态下对能力信息进行更新。例如,终端设备向服务小区对应的接入网设备发送该第三信息。
在一些实施例中,对于终端设备主动发起的能力信息更新过程,如图9所示,处于连接态的终端设备向网络设备发送第一信息,具体可以包括如下步骤S1~S4中的至少一个步骤:
步骤S1,终端设备向网络设备发送能力信息变更请求消息;
步骤S2,网络设备向终端设备发送能力信息变更允许消息;
步骤S3,终端设备向网络设备发送能力信息变更消息,该能力信息变更消息中包括第一信息,该第一信息用于更新终端设备的已有能力信息;
步骤S4,网络设备向终端设备发送能力信息变更完成消息。
在一些实施例中,对于网络侧(如接入网设备)查询的终端能力信息更新过程,如图10所示,处于连接态的终端设备向网络设备发送第一信息,具体可以包括如下步骤S11~S12中的至少一个步骤:
步骤S11,网络设备向终端设备发送能力信息查询请求消息;
步骤S12,终端设备向网络设备发送能力信息查询响应消息,该能力信息查询响应消息中包括第一信息,该第一信息用于更新终端设备的已有能力信息。
上述步骤S1~S4或S11~S12所示的流程,可以通过独立的RRC消息来完成,也可以包含于RRC重配置等消息中,本申请对此不作限定。
通过上述方式,可以完成终端能力信息在连接态下的更新,且简化复杂度。
