具体实施方式
下面结合附图并举实施例,对本申请提供的技术方案作进一步说明。应理解,本申请实施例中提供的系统结构和业务场景主要是为了解释本申请的技术方案的一些可能的实施方式,不应被解读为对本申请的技术方案的唯一性限定。本领域普通技术人员可以知晓,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(long term evolution,LTE)系统以及NR系统等,在此不做限制。需要说明的是,本申请可以应用于独立部署的5G或LTE系统,也应用于非独立部署的5G或LTE系统,比如双连接(dual-connectivity,DC)场景。
本申请实施例中,终端设备,可以为具有无线收发功能的设备或可设置于任一设备中的芯片,也可以称为用户设备(user equipment,UE)、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、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端、增强现实(augmented reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端等。
接入网设备,可以是NR系统中的下一代基站(next Generation node B,gNB),可以是LTE系统中的演进型基站(evolutional node B,eNB)等。
图1为适用本申请的一种网络架构示意图。如图1所示,终端设备可接入到接入网设备,以通过接入网设备获取外网(例如数据网络(data network,DN))的服务,或者通过接入网设备与其它设备通信,如可以与其它终端设备通信。
本申请实施例中,终端设备的能力(capability)可以是指根据终端设备的硬件和/或软件配置等因素确定的一种静态的能力,用于指示终端设备是否具有支持某一个特性(feature)或者特性集合(feature set)。例如终端设备的射频通道最大支持处理的带宽为100MHz,那么终端设备支持的最大带宽为100MHz。
终端设备的能力还可以是指动态配置的能力。例如可以根据工作环境等因素对终端的能力进行动态配置。例如,终端设备在网络中注册之后,在一些场景下,还可能希望变更能力信息。比如,终端设备出现过热问题;或者终端设备为了节省电量,降低功耗;或者终端设备由于硬件共享需求而需要调整能力;或者终端设备受到严重的干扰问题需要改变载波频率;或者终端设备出于业务需求而改变能力等。网络设备可以通过高层信令或者媒体接入控制(medium access control,MAC)层信令或者物理(physical,PHY)层信令等方式降低终端设备的能力。
本申请实施例中,以网络设备与终端设备之间交互为例进行说明,网络设备执行的操作也可以由网络设备内部的芯片或模块执行,终端设备执行的操作也可以由终端设备内部的芯片或模块执行。
结合前面的描述,如图2所示,为本申请实施例提供的一种通信方法流程示意图。参 见图2,该方法包括:
S201:终端设备确定指示信息。
本申请实施例中,指示信息可以携带在能力调整请求消息或者辅助信息中,或者指示信息也可以是指辅助信息。
其中,能力调整请求消息用于请求调整终端设备的能力。辅助信息也可以称为UE辅助信息,以下均统一称为辅助信息。终端设备可以通过辅助信息将希望的配置参数(例如下面的第一参数集合)上报给网络设备,网络设备可以参考终端设备上报的辅助信息进行RRC重配置,从而可以避免终端设备通过注册流程来更新能力,降低了时延和信令开销。
以上只是示例,指示信息还可以通过其他消息或信息携带,本申请实施例并不限定。
指示信息包括第一参数集合,第一参数集合用于网络设备基于第一参数集合调整终端设备的配置参数。举例来说,第一参数集合可以包括以下一项或多项:设备内共存(in-device coexistence,IDC)辅助信息;非连续接收(discontinuous reception,DRX)偏好参数;最大聚合带宽偏好参数;最大载波数目偏好参数;最大多输入输出(multi input multi output,MIMO)层数偏好参数;最小调度偏移量参数;无线资源控制(radio resource control,RRC)状态偏好参数;侧行链路辅助信息等。以上只是示例,第一参数集合还可以包括其他内容,在此不再逐一举例说明。
指示信息还可以包括第一信息或第二信息中的至少一项。第一信息,用于指示按照第一参数集合与网络设备进行数据传输的紧急程度或重要程度或迫切程度,或者用于指示按照第一参数集合进行重配置的紧急程度或重要程度或迫切程度。
终端设备具体如何确定紧急程度或重要程度或迫切程度,本申请并不限定。例如,终端设备可以根据终端设备的温度、电量情况、载波受干扰情况、射频能力占用情况、基带资源占用情况或业务类型等中的至少一项确定迫切程度/紧急程度/重要程度。
第一信息的具体实现方式可能存在多种。举例来说,第一种方式,第一信息为调整等级,调整等级越高表示按照第一参数集合进行数据传输或者对终端设备进行变更配置的紧急程度或重要程度或迫切程度越高。
比如预定义四个调整等级:等级0~等级3,等级0指示按照第一参数集合进行数据传输或者对终端设备进行变更配置的调整迫切程度/紧急程度/重要程度最低,等级3指示按照第一参数集合进行数据传输或者对终端设备进行变更配置的迫切程度/紧急程度/重要程度最高。在该情况下第一信息可以包括2比特,第一信息指示的调整等级可以参考表1所示。
表1
第一信息 调整等级
00 等级0
01 等级1
10 等级2
11 等级3
第二种方式,第一信息为调整因子,例如调整因子取值范围为0~1。调整因子越大表示迫切程度/紧急程度/重要程度越高。比如,当终端设备温度升高速度较慢,或终端设备电量降低速度较慢,或载波受干扰水平较低,或射频能力占用较低,或基带资源占用较低,或业务时延敏感时,迫切程度/紧急程度/重要程度可以认为较低,此时第一信息(调整因 子)的取值可以较小,例如0.2;而当终端设备温度升高速度较快,或UE电量降低速度较快,或载波受干扰水平较高,或射频能力占用较高,或基带资源占用较高,或业务时延不敏感时,此时第一信息(调整因子)的取值可以较大,例如0.8。
本申请实施例中,第一参数集合中的多个参数可以对应一个调整等级/调整因子,比如第一参数集合中包括用于节能的一个或多个偏好参数,则为节能定义一个调整等级/调整因子,所有与节能有关的偏好参数均对应该调整等级/调整因子。
另外,也可以为第一参数集合中的每个偏好参数上报一个调整等级/调整因子。比如,DRX偏好参数、最大带宽偏好参数、最大载波偏好参数、最大MIMO层数偏好参数等分别定义相应的调整等级/调整因子。网络设备根据每个参数对应的调整等级/调整因子进行重配。
第三种方式,紧急程度或重要程度可以为执行第一动作或触发第一事件的概率,此时第一信息可以为调整概率,指示网络设备不按照第一参数集合与终端设备进行数据传输时,终端设备将执行第一动作或触发第一事件的概率;或者指示当网络设备不参考第一参数集合进行重配,或网络设备重配超出第一参数集合的配置时,终端设备将执行第一动作或触发第一事件的概率。调整概率的取值范围可以为0%~100%。概率越大,表示能力调整的迫切程度/紧急程度/重要程度越高,终端设备执行第一动作或触发第一事件的可能性越大。
其中,第一动作以及第一事件的具体内容,将在后面进行描述,在此不再赘述。
本申请实施例中,第二信息,用于指示在收到针对指示信息拒绝消息的情况下或者未收到针对指示信息的响应信息的情况下,执行第一动作或触发第一事件。
其中,响应信息可以为网络设备接收到指示信息后发送的RRC重配消息,表示按照第一参数集合与终端设备进行数据传输,或者参考第一参数集合进行重配。
终端设备可以在发送指示信息时开始计时,计时的时长为预设时长,若在预设时长内收到针对所述指示信息的响应信息,且响应信息指示按照第一参数集合与终端设备进行数据传输,或者参考第一参数集合进行重配,则终端设备可以停止计时;在预设时长内,未收到响应信息,则执行第一动作或触发第一事件。预设时长可以由终端设备上报给网络设备,或由网络设备配置,或通过预定义的方式确定,本申请并不限定。
拒绝消息用于指示网络设备拒绝按照第一参数集合与终端设备进行数据传输,或者用于指示网络设备不参考第一参数集合进行重配。
本申请实施例中,第一动作包括以下至少一项:
1,上报无线链路失败;DC场景下,当终端设备在主小区组(master cell group,MCG)时,终端设备可以向主节点(master node,MN)上报MCG发生无线链路失败;当UE在辅小区组(secondary cell group,SCG)时,终端设备向MN上报SCG发生无线链路失败。

6,反馈NACK的概率增加;包括但不限于在RLC层反馈ARQ NACK的概率增加或在MAC层反馈HARQ NACK的概率增;反馈NACK的概率增加可以是指,当终端设备在RLC层接收数据时,在正确接收到数据的情况下,有一定概率反馈ARQ NACK;当终端设备在MAC层接收数据时,在正确接收到数据的情况下,有一定概率反馈HARQ NACK;

S204:网络设备根据指示信息中的第一信息或第二信息中的至少一项,确定基于第一参数集合对终端设备变更配置。
网络设备具体如何确定基于第一参数集合对终端设备变更配置,本申请实施例并不限定,在此不再赘述。
需要说明的是,网络设备是否基于第一参数集合对终端设备变更配置,具体根据实际情况确定,在此不再赘述。
通过本申请实施例提供的方法,终端设备可以通过上报第一信息表征按照第一参数集合进行配置或调整的迫切程度/紧急程度/重要程度,和/或通过第二信息上报网络设备不按照第一参数集合的配置进行调整的后果,使得网络设备能够根据第一参数集合进行重配置。通过这种方式,能够增大了终端设备进行能力调整的自主权。
本申请还提供一种能力调整的预协商方法,该方法中,终端设备能够通过与网络预先协商终端设备可能调整的能力,增大终端设备进行能力调整的自主权,同时降低了能力调整时调度的复杂度,提供能力调整的灵活性,下面将详细描述。
结合前面的描述,如图3所示,为本申请实施例提供的一种通信方法流程示意图。参见图3,该方法包括:
可选地,S301:终端设备向网络设备发送第二消息,第二消息包括第二指示信息。
第二消息的名称并不限定,例如可以为能力调整配置消息等。
其中,第二指示信息指示N个能力模式,N个能力模式中的一个能力模式对应一组能力信息集合,N为大于0的整数。能力信息集合可以包括以下至少一项能力:终端设备的 无线能力;终端设备的核心网能力;终端设备的定位能力。
需要说明的是,第二消息可以是终端设备与网络设备建立连接后向网络设备发送的能力调整配置消息,向网络指示UE可能调整的一个或多个能力模式。一个能力模式对应一组UE能力信息集合。这里的能力信息可以包括UE无线能力和/或UE核心网能力和/或UE定位能力。该消息可以通过RRC消息或非接入层(non-access stratum,NAS)消息发送到网络设备。示例性地,终端设备也可以在与网络设备进行RRC连接建立后通过一条独立的RRC消息或NAS消息,向网络设备发送第二指示信息。
示例性地,第二指示信息还可以是UE能力信息(UE capability information),或者第二指示信息还可以携带在UE能力信息中,终端设备可以在收到来自网络设备的UE能力查询(UE capability enquiry)消息后,向终端设备发送UE能力信息。
本申请实施例中,第二消息中可以包括N组能力信息集合,也可以不包括N组能力信息集合。第二消息中不包括N组能力信息集合时,可以预先建立能力模式与能力信息集合的对应关系,能力模式与能力信息集合的对应关系对终端设备和网络设备来说都是已知的,网络设备从而可以根据能力模式确定对应的能力信息集合。
举例来说,第二指示信息为一个比特位图,可以通过一个比特位图表示上报的能力模式,例如存在4个能力模式,分别为能力模式0至能力模式3。第二指示信息包括4个比特位,这4个比特位从左到右依次指示能力模式0至能力模式3,当比特位为0,表示终端设备不上报该比特位指示的能力模式;当比特位为1,表示终端设备上报该比特位指示的能力模式。比如第二指示信息为1011,表示第二指示信息指示的能力模式为能力模式0,能力模式2,和能力模式3。
再举例来说,还可以为每个能力模式配置一个模式标识,第二指示信息包括N个能力模式标识。例如,终端设备希望在能力模式0至能力模式3中进行能力调整,则可以上报能力模式0至能力模式3模式标识。
本申请实施例中,一组能力信息集合对应的能力,可以为终端设备全部能力的一部分,也可以为终端设备的全部能力。需要说明的是,本申请实施例中“能力信息”,是一个能力包含的功能或特性的集合,也可以称为能力信息集合或能力参数。
能力信息集合包括的内容,本申请并不限定。例如,能力信息集合可以包括以下能力信息:最大载波带宽;最大聚合载波数;最大MIMO层数。假设第二指示信息指示的3个能力模式对应的能力信息集合可以分别为:能力模式1对应的能力信息集合包括的信息为:最大载波带宽为200MHz,最大聚合载波数为8,最大MIMO层数为4;能力模式2对应的能力信息集合包括的信息为:最大载波带宽为100MHz,最大聚合载波数为4,最大MIMO层数为2;能力模式3对应的能力信息集合包括的信息为:最大载波带宽为50MHz,最大聚合载波数为2,最大MIMO层数为1。
需要说明的是,本申请可以预定义可调整的能力范围,在该预定义可调整的能力范围内,终端设备确定每个能力模式对应的能力信息集合。能力模式对应的能力信息集合可以在每终端设备级别的能力信令中上报给网络设备,可以在每频段组合(Band Combination,BC)的级别上报,可以在每频段(band)级别上报,也可以在每成员载波(Component Carrier,CC)级别上报。
本申请实施例中,能力模式还可以对应一个调整原因或调整目的,不同能力模式对应的调整原因或调整目的可以相同,也可以不同。举例来说,能力模式调整原因或能力模式 调整目可以包括但不限于以下任一项:
适用于终端设备的温度过高或过热时的能力模式;适用于节能的能力模式;适用于NR和无线局域网(wireless local area network,WLAN)能力共享时的能力模式;适用于多用户身份模块(subscriber identity module,SIM)卡能力共享时的能力模式;适用于车对万物(vehicle to everything,V2X)能力共享时的能力模式;适用于超高可靠低时延(ultra-high reliability and low latency,URLLC)业务的能力模式;适用于低能力(reduced capability,REDCAP)业务的能力模式。
终端设备可以显式或隐式地指示每个能力模式的调整原因或调整目的。终端设备显式指示时,可以在第二消息中携带调整指示信息,指示每种能力模式的调整原因或调整目的;终端设备隐式指示时,可以预先约定能力模式关联的调整原因或调整目的。
本申请实施例中,能力模式还可以对应其他信息,例如每个能力模式可以对应不同峰值速率等级等,具体不再赘述。
可选地,S302:网络设备接收来自终端设备的第二消息。
S303:网络设备向终端设备发送第一消息。
第一消息的名称并不限定,例如可以为能力调整配置确认消息等。
第一消息包括第一指示信息,第一消息或者第一指示信息可以指示M个能力模式,例如第一消息或者第一指示信息可以包括M个模式标识,一个模式标识对应一个能力模式。第一指示信息还可以用于指示允许请求将终端设备的能力调整为所述M个能力模式中的一个能力模式;M为大于0的整数。其中,允许请求将终端设备的能力调整为所述M个能力模式中的一个能力模式,可以是指允许终端设备向所述网络设备发送指示消息或请求消息;所述指示消息或所述请求消息用于指示将所述终端设备的能力模式调整为所述M个能力模式中的一个能力模式。
需要说明的是,如果终端设备发送的是指示消息,指示消息可以表示终端设备将按照该指示消息中指示的一个能力模式进行数据传输或者工作,所述一个能力模式属于M个能力模式。所述一个能力模式也可以携带在该指示消息中。终端设备可以不需要等待网络设备的反馈,终端设备认为网络设备会按照指示消息中指示的能力模式进行配置或重配置,重配置之后终端设备就按照该指示消息中指示的一个能力模式进行数据传输或者工作。需要注意的是,这里的反馈是指针对这个指示消息内容认同的反馈,并不是指正常数据传输流程中的ACK/NACK反馈。
如果终端设备发送的是请求消息,请求消息可以表示终端设备请求将按照该请求消息中指示的一个能力模式进行数据传输或者工作。终端设备需要等待网络设备的反馈。当终端设备根据网络设备的反馈,确定网络设备会按照请求消息中指示的能力模式进行配置时,再按照该请求消息中指示的一个能力模式进行数据传输或者工作。
本申请实施例中,一种可能的实现方式中,当终端设备通过第二消息指示N个能力模式时,M个能力模式可以为网络设备在终端设备上报的N个能力模式中选择的,具体如何选择,本申请并不限定。比如终端设备上报的希望调整的能力模式为能力模式1,能力模式2,能力模式3;网络设备可以允许终端设备调整到能力模式1和能力模式3,则通过第一指示信息指示能力模式1和能力模式3。
另一种可能的实现方式中,M个能力模式可以是协议预定义的,也可以是网络设备自主确定的。M个能力模式还可能存在其他确定方式,在此不再逐一举例说明。
在该实现方式中,第一消息的类型可以是广播消息或者是组播消息。网络设备可以通过广播消息或者组播消息向接入该网络设备的所有终端设备指示M个能力模式,也就是说向多个终端设备同时指示M个能力模式。
网络设备还可以通过广播消息或者组播消息向特定类型的终端设备指示M个能力模式,特定类型的终端设备包括但不限于低能力(reduced capability,REDCAP)终端设备,超高可靠低时延(ultra-high reliability and low latency,URLLC)终端设备以及车联网(vehicle to everything,V2X)终端设备等。
当然,通过第一消息指示的M个能力模式也可以仅针对一个终端设备,本申请实施例对此并不限定。
网络设备可以为每个能力模式配置相应的能力调整触发方式,此时第二消息中还可以包括触发信息;触发信息指示M个能力模式的能力调整触发方式。本申请实施例中,能力调整触发方式可以包括以下至少一项:第一触发方式,是指由终端设备触发进行能力调整;在该方式下,当终端设备需要进行能力调整时,向网络设备发送能力模式调整的指示。第二触发方式,是指由终端设备请求进行能力调整,并由网络设备确认进行能力调整。在该方式下,当终端设备需要进行能力调整时,向网络设备发送能力模式调整的指示,预设等待时间内期接收到网络设备的按需能力调整确认,则确定能力模式调整成功,其中,预设等待时间为网络设备配置的或终端设备设置的。第三触发方式,是指由网络设备触发进行能力调整。在该方式下,由网络设备触发是否进行能力调整,当网络设备由于业务需求需要对终端设备进行能力调整时,向终端设备发送按需能力调整指示,指示调整后的能力模式。
网络设备还可以为每个能力模式配置相应的能力恢复方式,此时第二消息中还可以包括恢复信息;恢复信息指示M个能力模式的能力恢复方式。本申请实施例中,能力恢复方式可以包括以下至少一项:第一恢复方式,是指基于定时时长的方式恢复能力调整之前的能力;在该方式中,当终端设备确定能力调整成功时,例如收到网络设备的RRC重配消息时,终端设备启动定时器,在定时器超时后终端设备恢复到能力调整之前的原始能力。定时器的定时时长为调整后的能力模式对应的应用时长,网络可以配置每个能力模式的应用时长,或者终端设备也可以在能力调整时向网络设备指示能力模式的应用时长。
第二恢复方式,是指由终端设备触发恢复能力调整之前的能力;在该方式中,终端设备向网络设备发送能力恢复指示,用于指示终端设备恢复到能力调整之前的原始能力。对于终端设备触发的能力调整(第一触发方式或第二触发方式),网络设备可以配置是否使能由终端设备触发能力恢复。
第三恢复方式,是指由网络设备触发恢复能力调整之前的能力。对于网络设备触发的能力调整(第三触发方式),网络设备可以向终端设备发送能力恢复指示,用于指示使终端设备恢复到原始能力。
需要说明的是,当网络设备为接入网设备时,对于终端触发的能力恢复,以及接入网设备触发的能力恢复,如果在进行能力模式调整时,接入网设备将终端设备调整后的能力模式发送给了核心网设备,在终端设备的能力恢复时,接入网设备也可以向核心网设备指示终端设备能力恢复后的能力。
S304:终端设备接收来自网络设备的第一消息。
需要说明的是,图3流程中的网络设备可以是指接入网设备,也可以是指核心设备, 下面分情况进行描述。

一种可能的实现方式中,能力调整配置消息为RRC消息,终端设备可以直接向接入网设备发送能力调整配置消息;另一种可能的实现方式中,能力调整配置消息为NAS消息,终端设备可以向核心网设备发送能力调整配置消息,由核心网设备将能力调整配置消息转发至接入网设备。
其中,第二消息中包括的N组能力信息集合的具体内容不做限制,例如能力信息集合中可以包括终端设备的无线能力,包括射频(radio frequency,RF)能力,测量和移动性能力,层2的能力等。
S402:接入网设备向终端设备发送能力调整配置确认消息。
能力调整配置确认消息包括第一指示信息,能力调整配置确认消息可以是指前面的第一消息。
S403:接入网设备向核心网设备发送能力模式配置消息。
能力模式配置消息可以指示M个能力模式。
以网络设备为核心网设备为例,如图5所示,为本申请提供的一种能力调整配置流程示意图。
S501:终端设备向核心网设备发送能力调整配置消息。
能力调整配置消息包括第二指示信息,能力调整配置消息可以是指前面的第二消息。

一种可能的实现方式中,能力调整配置消息为NAS消息,终端设备可以通过接入网设备向核心网设备发送能力调整配置消息,其中接入网设备接收到来自终端设备的NAS消息时,透明转发至核心网设备。
另一种可能的实现方式中,能力调整配置消息为RRC消息,终端设备可以向接入网设备发送能力调整配置消息,由接入网设备将能力调整配置消息转发至核心网设备,在该实现方式中。

S503:核心网设备还可以向接入网设备发送能力调整配置辅助消息。能力调整配置辅助消息指示M个能力模式。
这M个能力模式为终端设备进行能力调整时的候选能力模式,为允许终端设备调整的M个能力模式。
以网络设备为接入网设备为例,如图6所示,为本申请提供的一种能力调整配置流程示意图。
S601:终端设备向核心网设备发送能力调整配置消息。能力调整配置消息可以是指前面的第二消息。

在该场景中,能力调整配置消息可以为NAS消息,终端设备可以直接向核心网设备发送能力调整配置消息。
S602:核心网设备向终端设备发送能力调整配置确认消息。能力调整配置确认消息可以是指前面的第一消息。
通过前面的过程,终端设备能够通过与网络设备进行预先协商,确定出终端设备可以从M个能力模式中选择能力模式进行能力调整,增大终端设备能力调整的自主权,同时由于终端设备将可能调整的能力模式已经事先上报给了网络设备,因此在终端能力模式改变的情况下,可以降低网络设备调度多能力模式终端设备的复杂度。
本申请实施例中,在终端设备与网络设备预先协商M个能力模式之后,终端设备或者网络设备可以触发对终端设备的能力进行调整,其中,网络设备可以是接入网设备,也可以是核心网设备,接入网设备可以是指gNB或者eNB等,核心网设备可以是指接入和移动性管理功能(access and mobility management function,AMF)网元或者位置管理功能(location management function,LMF)网元等,下面分不同情况进行描述。
