Description

一种无线通信方法及无线通信装置
本申请要求在2018年4月28日提交中华人民共和国知识产权局、申请号为201810402941.6、发明名称为“一种无线通信方法及无线通信装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域,尤其涉及一种无线通信方法及无线通信装置。
背景技术
随着无线和有线技术的不断发展,通信带宽不断提升,1000Mbps以上的产品已经开始出现,为更丰富多彩的终端应用创造了条件,但受制于手持终端的尺寸和成本,终端的处理能力、功耗和发热逐渐成为瓶颈。
终端功耗的上升带来的一个直接后果就是设备散热问题,设备正常工作有个合适的温度区间,一旦温度超过范围,系统稳定性就会下降,甚至可能引起设备损坏等比较严重的后果。终端的处理能力通常能够应付正常的业务场景,但复杂业务场景常常导致终端超负载运行,一旦系统长时间超负载运行对软件系统的调度和整个系统的稳定性都是个严峻的挑战。
现有技术中,一般根据经验值设计业务模型,在出现极端场景如终端设备的温度较高(过热)、处理器过载、电量过低等,需要进行极端场景保护,如丢包、重启等,避免系统不能提供正常服务。其中,丢包是在系统资源处理临界状态时,将处理不完的数据直接丢弃;然而,由于丢包时不区分业务,从而导致无法满足不同业务的服务质量(quality of service,QoS)要求,而且丢包会导致难以预料的重传,可能会浪费带宽资源。重启是指一旦终端设备长时间处于过热或过载状态,则认为系统异常,直接进行重启,这样可以立即将系统负载归零;然而,重启本身会损害系统的健壮性,导致业务体检不好。
综上,现有技术中在进行极端场景保护时,仍存在一些不足。因此,目前亟需一种通信方法,用于在终端设备与网络设备进行通信的过程中出现极端场景时,能够有效实现极端场景保护。

终端设备是一种具有无线收发功能的设备,可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫 星上等)。所述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)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self driving)中的无线终端设备、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等。
本申请中主要以图1所示意的系统架构为例进行介绍,但并不限于此。
上述系统架构适用的通信系统包括但不限于:时分双工-长期演进(time division duplexing-long term evolution,TDD LTE)、频分双工-长期演进(frequency division duplexing-long term evolution,FDD LTE)、长期演进-增强(long term evolution-advanced,LTE-A),以及未来演进的各种无线通信系统(例如,5G NR系统)。
在图1所示的系统架构中,终端设备和网络设备进行通信的过程中,可能会出现终端设备的温度较高、处理器过载、电量过低等极端场景,进而会导致一系列的问题,因此需要对终端设备进行极端场景保护(比如过热保护、过载保护、节电保护等,具体不做限定)。
一种过热保护的实现方式为:终端设备向网络设备上报支持过热保护特性,相应地,网络设备配置使能过热保护检测;终端设备检测到终端设备的温度过高(过热)后,向网络设备上报能力下降目标(比如,上行目标能力等级、下行目标能力等级、上行载波个数、下行载波个数),网络设备可根据终端设备上报的能力下降目标,降低终端设备的相关配置,并减少对终端设备的调度。当终端设备检测到温度恢复正常(不再过热)后,向网络设备上报释放过热保护的能力,相应地,网络设备恢复终端设备的相关配置和调度。
上述方式中终端设备检测到过热后,一次性把终端设备的能力降到足够低(即将终端设备与网络设备之间的传输速率由终端设备支持的最大传输速率降低为终端设备支持的最小传输速率),温度恢复正常后,一次性解除过热保护,即一次性将终端设备的能力由足够低提高到正常。由此可知,上述方式在进行过热保护过程中,终端设备的能力的调整幅度(包括终端设备的能力的降低幅度和终端设备的能力的提高幅度)较大,可能会影响用户体验;且由于终端设备的能力的提高幅度较大,使得在解除过热保护后可能会导致温度快速反弹,又需要再次进行过热保护,从而可能会形成一种颠簸状态,在流量上会有显著的锯齿状,用户能够明显感知到通信速度不稳定,时快时慢。
基于此,本申请实施例提供一种无线通信方法,用于解决进行极端场景保护时由于终端设备的能力的调整幅度较大而导致通信速度不稳定、影响用户体验的技术问题。其中,本申请实施例中的第一无线通信装置可以为图1中所示意的任一个终端设备或者终端设备中的半导体芯片,其中,当所述第一无线通信装置为半导体芯片时,无线通信装置可以为片上系统(System-on-a-Chip,SoC)主芯片或者基带调制解调(modem)芯片。所述第二无线通信装置可以为图1中所示意的网络设备或者网络设备中的半导体芯片。
实施例一
图2为本申请实施例提供的一种无线通信方法所对应的流程示意图。该无线通信方法可以应用于第一无线通信装置,所述第一无线通信装置被配置为具有多种无线通信能力。如图2所示,该方法包括:
步骤201,在所述第一无线通信装置使用第一无线通信能力与第二无线通信装置进行 通信时,所述第一无线通信装置若确定调整所述第一无线通信装置的无线通信能力,则向所述第二无线通信装置发送第一调整信息,并启动第一定时器,所述第一调整信息用于指示所述第一无线通信装置的无线通信能力调整为第二无线通信能力;
步骤202,在所述第一定时器的设定时间内,所述第一无线通信装置使用所述第二无线通信能力与所述第二无线通信装置进行通信。
本申请实施例中,第二无线通信能力为多种无线通信能力中除最大无线通信能力和最小无线通信能力以外的任一种无线通信能力,也就是说,在对无线通信能力进行调整时,调整的幅度较小,从而能够有效避免调整幅度较大而导致通信速度不稳定、影响用户体验的技术问题;进一步地,由于第一无线通信装置被配置有多种无线通信能力,因此,在达到第一定时器的设定时间后,第一无线通信装置可以循环执行上述步骤,从而能够实现对第一无线通信装置的无线通信能力进行逐步调整,用更平滑的方式进行极端场景保护,使得第一无线通信装置在通信过程中能够维持在一个相对平衡的状态,为用户提供较为稳定的服务,提高用户体验。
第一无线通信装置确定调整第一无线通信装置的无线通信能力,具体可以为:第一无线通信装置确定降低第一无线通信装置的无线通信能力,或者,第一无线通信装置确定提高第一无线通信装置的无线通信能力。
具体来说,第一无线通信装置确定降低第一无线通信装置的无线通信能力(此时,所述第一无线通信能力可以为除最小无线通信能力以外的任一种无线通信能力)的情形,可以有多种,相应地,第一无线通信装置确定提高第一无线通信装置的无线通信能力(此时,所述第一无线通信能力可以为除最大无线通信能力以外的任一种无线通信能力)的情形,也可以有多种。
在一个示例中,本申请实施例中的方法可以分别单独适用于各种极端场景保护,比如过热保护、过载保护、节电保护。
具体来说,在过热场景保护中,第一无线通信装置若确定第一无线通信装置的温度大于第一温度阈值,则可确定降低第一无线通信装置的无线通信能力;或者,若确定所述第一无线通信装置的温度小于第二温度阈值,则可确定提高第一无线通信装置的无线通信能力。在过载场景保护中,第一无线通信装置若确定处理器负载大于第一负载阈值,则可确定降低第一无线通信装置的无线通信能力;或者,若确定处理器负载小于第二负载阈值,则可确定提高第一无线通信装置的无线通信能力。在节电场景保护中,第一无线通信装置若确定电池电量小于第一电量阈值,则可确定降低第一无线通信装置的无线通信能力;或者,若确定电池电量大于第二电量阈值或者电池处于充电状态,则可确定提高第一无线通信装置的无线通信能力。
在另一个示例中,本申请实施例也可以综合考虑多种极端场景保护,比如综合考虑过热保护、过载保护、节电保护,从而能够更合理有效地实现极端场景保护。
具体来说,第一无线通信装置若确定第一无线通信装置的温度大于第一温度阈值,或者终端设备的电池电量小于第一电量阈值,又或者处理器负载大于第一负载阈值,则可确定降低第一无线通信装置的无线通信能力;或者,若确定第一无线通信装置的温度小于第二温度阈值、电池电量大于第二电量阈值、且处理器负载小于第二负载阈值,则确定提高所述第一无线通信装置的无线通信能力;又或者,若确定所述第一无线通信装置的温度小于第二温度阈值、所述电池处于充电状态、且所述处理器负载小于第二负载阈值,则确定 提高所述第一无线通信装置的无线通信能力。
上述所涉及的第一温度阈值、第一电量阈值、第一负载阈值、第二温度阈值、第二电量阈值、第二负载阈值的大小均可以由本领域技术人员根据实际需要进行设置,具体不做限定。进一步地,第二温度阈值可以略小于第一温度阈值,第二电量阈值可以略大于第一电量阈值,第二负载阈值可以略小于第一负载阈值。以过热保护为例,第一无线通信装置若确定第一无线通信装置的温度大于第一温度阈值(比如100摄氏度),则可启动过热保护,在温度下降到第二温度阈值(比如80摄氏度)以下时,则可解除过热保护,由于第二温度阈值略小于第一温度阈值,从而能够使得第一无线通信装置的温度可以稳定在80摄氏度至100摄氏度的范围内,避免频繁调整第一无线通信装置的无线通信能力,提供尽可能好的用户体验。
本申请实施例中,第一无线通信装置为终端设备中的半导体芯片时,第一无线通信装置的温度即是指半导体芯片的温度,此时,第一温度阈值可以为半导体芯片对应的温度阈值。第一无线通信装置为终端设备时,第一无线通信装置的温度可以是指终端设备中的一个或多个模块的温度,比如半导体芯片、电池、客户识别模块(subscriber identity module,SIM)卡等,相应地,第一温度阈值可以为半导体芯片、电池、SIM卡对应的温度阈值,具体不做限定。
本申请实施例中,第一无线通信装置所具有的多种无线通信能力可以为预先配置的。具体实施中,可以由本领域技术人员通过设置影响第一无线通信装置的无线通信能力的各项参数的大小来配置。其中,影响第一无线通信装置的无线传输能力大小的参数可以有一种或多种。在一个示例中,影响第一无线通信装置的无线传输能力大小的参数包括以下任一项或任意组合:第一无线通信装置支持的上行能力等级;第一无线通信装置支持的下行能力能级;第一无线通信装置支持的上行载波个数;第一无线通信装置支持的下行载波个数;第一无线通信装置支持的BWP的大小;第一无线通信装置支持的多输入多输出(multiple-input multiple-output,MIMO)能力;缓存状态上报(buffer status report,BSR)加权系数。需要说明的是,上述列举仅为一种示例性说明,在其它可能的实施例中,也可以包括其它的参数,具体不做限定。
在一个示例中,第一无线通信装置为LTE通信系统中的终端设备,影响第一无线通信装置的无线传输能力大小的参数包括第一无线通信装置支持的上行能力等级、第一无线通信装置支持的下行能力能级、第一无线通信装置支持的上行载波个数和第一无线通信装置支持的下行载波个数。第一无线通信装置的不同无线通信能力对应的上述参数的大小可能不同。如表1所示,为第一无线通信装置的多种无线通信能力分别对应的参数的大小示例。
表1:多种无线通信能力分别对应的参数的大小示例1
无线通信能力 下行能力等级 上行能力等级 下行载波个数 上行载波个数
无线通信能力1 category19 category13 4 2
无线通信能力2 category12 category13 2 2
无线通信能力3 category12 category5 2 1
无线通信能力4 category6 category5 1 1
在另一个示例中,第一无线通信装置为NR通信系统中的终端设备,影响第一无线通信装置的无线传输能力大小的参数包括第一无线通信装置支持的上行载波个数和第一无 线通信装置支持的下行载波个数、第一无线通信装置支持的BWP的大小、第一无线通信装置支持的MIMO能力,其中,MIMO能力具体可以包括MIMO的层数、不支持MIMO等。第一无线通信装置的不同无线通信能力对应的上述参数的大小可能不同。如表2所示,为第一无线通信装置的多种无线通信能力分别对应的参数的大小示例。
表2:多种无线通信能力分别对应的参数的大小示例2
无线通信能力 下行载波个数 上行载波个数 BWP的大小 MIMO能力
无线通信能力1 4 2 100MHz 8层
无线通信能力2 2 2 100MHz 8层
无线通信能力3 2 1 100MHz 8层
无线通信能力4 1 1 20MHz 8层
无线通信能力5 1 1 20MHz 2层
无线通信能力6 1 1 20MHz 不支持MIMO
需要说明的是,上述表1和表2仅为一种简单示例,具体实施中,可以根据实际需要进行多种可能的配置,具体不做限定。
根据以上内容可知,第一调整信息中可以包括以下任一项或任意组合:第二无线通信能力对应的上行能力等级,用于指示所述第一无线通信装置支持的上行能力等级调整为所述第二无线通信能力对应的上行能力等级;第二无线通信能力对应的下行能力能级,用于指示所述第一无线通信装置支持的下行能力等级调整为所述第二无线通信能力对应的下行能力等级;第二无线通信能力对应的上行载波个数,用于指示所述第一无线通信装置支持的上行载波个数调整为所述第二无线通信能力对应的上行载波个数;第二无线通信能力对应的下行载波个数,用于指示所述第一无线通信装置支持的下行载波个数调整为所述第二无线通信能力对应的下行载波个数;第二无线通信能力对应的BWP的大小,用于指示所述第一无线通信装置支持的BWP的大小调整为所述第二无线通信能力对应的BWP的大小;第二无线通信能力对应的多输入多输出MIMO能力,用于指示所述第一无线通信装置支持的MIMO能力调整为所述第二无线通信能力对应的MIMO能力;第二无线通信能力对应的BSR值,所述第二无线通信能力对应的BSR值是所述第一无线通信装置根据所述第二无线通信能力对应的BSR加权系数得到的。第二调整信息和第三调整信息中所包括的内容可参照上述第一调整信息中所包括的内容,不再赘述。
本申请实施例中,针对于第一调整信息中可能包括的第二无线通信能力对应的MIMO能力、第二无线通信能力对应的的载波个数(包括上行载波个数和下行载波个数)、第二无线通信能力对应的的能力等级(包括上行能力等级和下行能力等级)等,这些内容可以通过用户辅助信息(UEAssistanceInformation)上报给第二无线通信装置,且可以在上报时启动定时器;进一步地,在升速过程中,若第一无线通信装置恢复至正常能力,则通过UEAssistanceInformation上报上述内容时,OverheatingAssistance IE可以不包含相关信息,用于指示网络设备终端设备恢复到正常能力。针对于第一调整信息中可能包括的第二无线通信能力对应的BSR值,则可以不通过UEAssistanceInformation上报,而是在MAC需要上报BSR时,直接将BSR值发送给第二无线通信装置,并且可以在调整BSR加权系数时启动定时器,而并非上报BSR值时启动定时器。
本申请实施例中,由于第一无线通信装置使用不同的无线通信能力与第二无线通信装 置进行通信时,传输速率的上限值也不同(即不同的无线通信能力对应不同的传输速率的上限值),因此,降低无线通信能力可以理解为降低第一无线通信装置与第二无线通信装置之间的传输速率的上限值(降速),提高无线通信能力可以理解为提高第一无线通信装置与第二无线通信装置之间的传输速率的上限值(升速)。进一步地,降速周期和升速周期可以仅使用一个定时器(比如第一定时器)来控制,或者,降速周期和升速周期也可以分别使用不同的定时器(比如第一定时器和第二定时器)来控制。
当降速周期和升速周期分别使用不同的定时器来控制时,上述方法还可以包括:在第一无线通信装置使用第二无线通信能力与第二无线通信装置进行通信时,第一无线通信装置若确定调整第一无线通信装置的无线通信能力,则向第二无线通信装置发送第二调整信息,并启动第二定时器,第二调整信息用于指示第一无线通信装置的无线通信能力调整为第三无线通信能力;在第二定时器的设定时间内,第一无线通信装置使用第三无线通信能力与第二无线通信装置进行通信。
其中,若第一无线通信能力大于第二无线通信能力,第二无线通信能力小于第三无线通信能力,则可以理解为:降速周期使用第一定时器来控制,升速周期使用第二定时器来控制,此时,第一无线通信装置若确定提高第一无线通信装置的无线通信能力,则可以忽略正在运行的第一定时器,直接启动第二定时器。若第一无线通信能力小于第二无线通信能力,第二无线通信能力大于第三无线通信能力,则可以理解为:升速周期使用第一定时器来控制,降速周期使用第二定时器来控制,此时,第一无线通信装置若确定降低第一无线通信装置的无线通信能力,则可以忽略正在运行的第一定时器,直接启动第二定时器。如此,通过使用不同的定时器来分别控制升速周期和降速周期,能够有效保证传输速率的及时调整,而无需等待达到第一定时器的设定时间。
本申请实施例中,所述第一无线通信能力为所述多种无线通信能力中的最大无线通信能力时,第一传输速率与第二传输速率的差值的绝对值为第一数值;所述第一无线通信能力为除所述最大无线通信能力以外的其它无线通信能力时,所述第一传输速率与所述第二传输速率的差值的绝对值为第二数值;所述第一数值大于所述第二数值;其中,所述第一传输速率为所述第一无线通信装置使用所述第一无线通信能力与所述第二无线通信装置进行通信时,传输速率的上限值;所述第二传输速率为所述第一无线通信装置使用所述第二无线通信能力与所述第二无线通信装置进行通信时,传输速率的上限值。也就是说,当第一无线通信装置的无线通信能力为最大无线通信能力时调整的幅度大于其它情形下调整的幅度,从而在将无线通信能力由最大无线通信能力进行降低时,可以降低得快一些,有效避免第一无线通信装置在极端场景下进入异常状态。
本申请实施例中,上述方法还可以包括:在第一无线通信装置使用第二无线通信能力与第二无线通信装置进行通信时,第一无线通信装置若确定调整第一无线通信装置的无线通信能力,则向第二无线通信装置发送第三调整信息,第三调整信息用于指示第一无线通信装置的无线通信能力调整为第四无线通信能力;第一无线通信装置使用第四无线通信能力与第二无线通信装置进行通信;其中,第四无线通信能力为最大无线通信能力或最小无线通信能力。也就是说,当在升速过程中将第一无线通信装置的无线通信能力调整为最大无线通信能力,或者在降速过程中将第一无线通信装置的无线通信能力调整为最小无线通信能力时,由于在相应的方向上已无法再进行调整,因此可以不再启动定时器,从而节省处理资源。
下面以第一无线通信装置为终端设备、第二无线通信装置为网络设备为例,结合图3a和图3b对本申请实施例中调整无线通信能力的可能情形进行说明,其中,图3a和图3b所示例出的仅为终端设备在某一时间段内的调整过程。根据上述的描述可知,终端设备使用的无线通信能力与终端设备和网络设备之间的传输速率的上限值存在对应关系,因此,在图3a和图3b中以传输速率的上限值的调整来示意无线通信能力的调整。
图3a为本申请实施例提供的一种无线通信能力的调整过程示例图。在图3a的示例中,终端设备至少被配置为具有四种无线通信能力:无线通信能力1对应的传输速率的上限值为传输速率a0,无线通信能力2对应的传输速率的上限值为传输速率a1,无线通信能力3对应的传输速率的上限值为传输速率a2,无线通信能力4对应的传输速率的上限值为传输速率a3。
如图3a所示,阶段①:终端设备与网络设备之间的传输速率的上限值为传输速率a0,其中,传输速率a0为终端设备具有的多种无线通信能力中的最大无线通信能力对应的传输速率的上限值。阶段②:终端设备若确定需要降低所述传输速率的上限值,则首次启动降速,此时传输速率的上限值由传输速率a0降为传输速率a1,降速周期为第一定时器的设定时间。阶段③:当达到第一定时器的设定时间后,终端设备若确定仍需要降低所述传输速率的上限值,则再次启动降速,此时传输速率的上限值由传输速率a1降为传输速率a2,降速周期为第一定时器的设定时间。阶段④:当达到第一定时器的设定时间后,终端设备若确定仍需要降低所述传输速率的上限值,则再次启动降速,此时传输速率的上限值由传输速率a2降为传输速率a3,降速周期为第一定时器的设定时间。需要说明的是,若传输速率a3为终端设备具有的多种无线通信能力中的最小无线通信能力对应的传输速率的上限值,则也可以不再启动第一定时器。阶段⑤:当达到第一定时器的设定时间后,终端设备若确定不再调整所述传输速率(平衡点),则保持当前状态,传输速率的上限值仍为传输速率a3。阶段⑥:终端设备若确定提高所述传输速率的上限值,则启动升速过程,此时传输速率的上限值由传输速率a3升为传输速率a2,升速周期为第一定时器的设定时间。阶段⑦:当达到第一定时器的设定时间后,终端设备若仍确定提高所述传输速率的上限值,则再次启动升速,此时传输速率的上限值由传输速率a2升为传输速率a1,升速周期为第一定时器的设定时间。阶段⑧:当达到第一定时器的设定时间后,终端设备若确定需要降低所述传输速率的上限值,则启动降速,此时传输速率的上限值由传输速率a1降为传输速率a2,降速周期为第一定时器的设定时间。阶段⑨:当达到第一定时器的设定时间后,终端设备若确定需要提高所述传输速率的上限值,则启动升速,此时传输速率的上限值由传输速率a2升为传输速率a1,升速周期为第一定时器的设定时间。阶段⑩:当达到第一定时器的设定时间后,终端设备若确定仍需要提高所述传输速率的上限值,则再次启动升速,此时传输速率的上限值由传输速率a1升为传输速率a0,此时可不再启动第一定时器。后续终端设备若确定不需要调整所述传输速率的上限值(平衡点),则保持当前状态,传输速率的上限值为传输速率a0。上述描述中所涉及的降速过程和升速过程均可通过执行上述步骤201和步骤202来实现。
根据上述描述可知:(1)降速周期和升速周期均通过同一个定时器(比如第一定时器)来控制;(2)a0-a1、a1-a2、a2-a3的值可以相同,或者也可以不同,也就是说,每次对传输速率的上限值进行调整的调整幅度大小可以不做限定,具体由本领域技术人员根据实际需要进行配置;(3)在降速过程中,由传输速率a0依次降低到传输速率a3,在升速过 程中,由传输速率a3依次提高到传输速率a0。
图3b为本申请实施例提供的又一种无线通信能力的调整过程示例图。在图3b的示例中,终端设备至少被配置为具有五种无线通信能力:无线通信能力1对应的传输速率的上限值为传输速率b0,无线通信能力2对应的传输速率的上限值为传输速率b1,无线通信能力3对应的传输速率的上限值为传输速率b2,无线通信能力4对应的传输速率的上限值为传输速率b3,无线通信能力5对应的传输速率的上限值为传输速率b4。
如图3a所示,阶段①:终端设备与网络设备之间的传输速率的上限值为传输速率b0,其中,传输速率b0为终端设备具有的多种无线通信能力中的最大无线通信能力对应的传输速率的上限值。阶段②:终端设备若确定需要降低所述传输速率的上限值,则首次启动降速,此时传输速率的上限值由传输速率b0降为传输速率b1,降速周期为第一定时器的设定时间。阶段③:当达到第一定时器的设定时间后,终端设备若确定仍需要降低所述传输速率的上限值,则再次启动降速,此时传输速率的上限值由传输速率b1降为传输速率b2,降速周期为第一定时器的设定时间。阶段④:当达到第一定时器的设定时间后,终端设备若确定仍需要降低所述传输速率的上限值,则再次启动降速,此时传输速率的上限值由传输速率b2降为传输速率b3,降速周期为第一定时器的设定时间。需要说明的是,若传输速率b3为终端设备具有的多种无线通信能力中的最小无线通信能力对应的传输速率的上限值,则也可以不再启动第一定时器。阶段⑤:当达到第一定时器的设定时间后,终端设备若确定不需要调整所述传输速率(平衡点),则保持当前状态,传输速率仍为传输速率b3。阶段⑥:终端设备若确定提高所述传输速率的上限值,则启动升速过程,此时传输速率的上限值由传输速率b3升为传输速率b2,升速周期为第二定时器的设定时间。阶段⑦:当达到第二定时器的设定时间后,终端设备若确定提高所述传输速率的上限值,则再次启动升速,此时传输速率的上限值由传输速率b2升为传输速率b1,升速周期为第二定时器的设定时间。阶段⑧:终端设备若确定需要降低所述传输速率的上限值,则启动降速,此时传输速率的上限值由传输速率b1降为传输速率b2,降速周期为第一定时器的设定时间。阶段⑨:当达到第一定时器的设定时间后,终端设备若确定提高所述传输速率的上限值,则启动升速,此时传输速率的上限值由传输速率b2升为传输速率b1,升速周期为第二定时器的设定时间。阶段⑩:当达到第二定时器的设定时间后,终端设备若确定提高所述传输速率的上限值,则再次启动升速,此时传输速率的上限值由传输速率b1升为传输速率b4,升速周期为第二定时器的设定时间。达到第二定时器的设定时间后,终端设备若确定不需要调整所述传输速率(平衡点),则保持当前状态,传输速率为传输速率b4。上述描述中所涉及的降速过程和升速过程均可通过执行上述步骤201和步骤202来实现。
根据上述描述可知:(1)降速周期通过第一定时器来控制,升速周期通过第二定时器来控制,因此,在升速过程中,若确定需要降低传输速率,则可立即启动降速过程(参见图3b所示意的阶段⑧),避免需要等待达到第二定时器的设定时间后才能启动降速,从而能够实现及时降速,更加有效地实现极端场景保护;同样地,在降速过程中,若确定需要提高传输速率,则也可以立即启动升速过程。在其它实施例中,也可以是降速周期通过第二定时器来控制,升速周期通过第一定时器来控制,具体不做限定。(2)在不同阶段,传输速率的上限值的调整幅度可以不同,比如,首次启动降速时,调整幅度较大,从而能够避免第一无线通信装置在极端场景下进入异常状态。且,由于降速和升速分别使用不同的定时器,因此,具体实施中,可以通过控制第一定时器和第二定时器的时长来实现较快的 降速和较慢的升速(即快降慢升)。
下面结合具体实施例(实施例二至实施例六)对本申请实施例进行示例性说明。
实施例二
实施例二中,适用的通信系统可以为LTE通信系统,适用的场景为过热保护,使用一个定时器(比如定时器T345)来控制升速周期和降速周期。
初始状态:终端设备支持下行Category 19和上行Category 13,网络设备按照终端设备支持的最大无线通信能力调度终端设备。
阶段①,终端设备检测到终端设备的芯片温度大于110摄氏度,则确定终端设备的温度过高,向网络设备发送调整信息,并启动定时器T345。调整信息中包括下行2载波和下行Category 12,用于指示终端设备支持的下行载波个数调整为2、终端设备支持的下行能力等级调整为下行Category 12。
阶段②,终端设备确定定时器T345超时后,检测并确定芯片温度仍大于110摄氏度,则再次上报调整信息,并启动定时器T345。调整信息中包括上行1载波和上行Category 5,用于指示终端设备支持的上行载波个数调整为1、终端设备支持的上行能力等级调整为上行Category 5。

阶段⑦,终端设备确定定时器T345超时后,检测到芯片温度低于100度,终端设备再次再次上报调整信息,调整信息中包括下行Category 19,用于指示终端设备支持的下行能力等级调整为下行Category 19。此时,由于已恢复终端设备的正常能力,因此,可不再启动定时器T345,从而便于一旦温度快速上升可以立即降低终端设备的能力;并且OverheatingAssistance IE不包含相关信息,用于指示终端设备恢复到正常能力。
实施例三
实施例三与实施例二的差别在于:增设一个定时器,暂表示为T346,作为控制升速周期的定时器,其原理与T345相同,如此,T345只用于控制降速周期。过热保护需要启动 降速过程时,需要T345不在运行状态;温度恢复需要启动升速过程时,需要T346不在运行状态。
初始状态:终端设备支持下行Category 19和上行Category 13,网络设备按照终端设备支持的最大无线通信能力调度终端设备。
阶段①,终端设备检测到终端设备的芯片温度大于110摄氏度,则确定终端设备的温度过高,并向网络设备发送调整信息,并启动定时器T345。调整信息中包括下行2载波和下行Category 12,用于指示终端设备支持的下行载波个数调整为2、终端设备支持的下行能力等级调整为下行Category 12。
阶段②,终端设备确定定时器T345超时后,检测并确定芯片温度仍大于110摄氏度,则再次上报调整信息,并启动定时器T345。调整信息中包括上行1载波和上行Category 5,用于指示终端设备支持的上行载波个数调整为1、终端设备支持的上行能力等级调整为上行Category 5。

阶段⑧,终端设备检测到芯片温度低于100度,芯片温度恢复正常,可以启动升速过程,因为BSR加权系数HotWeight小于1,所以首先调节HotWeight,并启动定时器T345。
在一个示例中,调整BSR加权系数HotWeight具体实现方式可以为:将上升系数HotUp设置为1.03,即调整后的HotWeight=HotWeight*HotUp。当终端设备确定媒体访问控制(media access control,MAC)层需要上报缓存状态BSR时,BSR值为按协议规则计算出的BSR*HotWeight。
需要说明的是,在芯片温度小于100摄氏度的情况下,可以多次调整BSR加权系数HotWeight,直至BSR加权系数HotWeight恢复正常,此处不再赘述。

阶段②,终端设备确定定时器T345超时后,检测并确定处理器负载仍然过大,则再次上报调整信息,并启动定时器T345。调整信息中包括上行1载波,用于指示终端设备支持的上行载波个数调整为1。
需要说明的是,在过载保护过程时,如果配置定时器的时长大于或等于1秒,则可以取1秒作为定时器的时长,从而便于更加合理有效地调整处理器的负载。
阶段③,终端设备确定定时器T345超时后,检测并确定处理器负载仍然过大,则再次上报调整信息,并启动定时器T345。调整信息中包括下行1载波,用于指示终端设备支持的下行载波个数调整为1。
阶段④,终端设备确定定时器T345超时后,检测并确定处理器负载仍然过大,则再次上报调整信息,并启动定时器T345。调整信息中包括BWP 20MHz、MIMO能力(具体为不支持MIMO),用于指示终端设备支持的BWP的大小调整为20MHz(低频),且终端 设备不支持MIMO。
阶段⑤,终端设备确定定时器T345超时后,检测并确定处理器负载仍然过大,但是按协议已经无法再下调终端设备的能力,这时开始调整BSR加权系数CpuWeight,并启动定时器T345。
在一个示例中,调整BSR加权系数CpuWeight具体实现方式可以为:初始时CpuWeight为1,可设置下降系数CpuDown为0.9,即调整后的CpuWeight=CpuWeight*CpuDown。当终端设备确定MAC需要上报缓存状态BSR时,BSR值为按协议规则计算出的BSR*CpuWeight。
阶段⑥,终端设备确定定时器T345超时后,检测并确定处理器余量为8%,属于较高区域,但并无风险,终端设备可保持当前能力状态。
阶段⑦,终端设备检测到处理器余量大于10%,处理器负载恢复正常,可以启动升速过程,因为BSR加权系数CpuWeight小于1,所以首先调节CpuWeight,并启动定时器T345。
在一个示例中,调整BSR加权系数CpuWeight具体实现方式可以为:设置上升系数CpuUp为1.03,即调整后的CpuWeight=CpuWeight*CpuUp。
阶段⑧,终端设备确定定时器T345超时后,检测到处理器余量大于10%,并且CpuWeight大于等于1,此时,终端设备开始上调能力,具体地,终端设备上报调整信息,并启动定时器T345。调整信息中包括MIMO能力(4*4),用于指示终端设备支持MIMO 4*4。
在随后的过程中,终端设备确定定时器T345超时后,可分多次分别上调BWP的大小、下行载波个数和上行载波个数。终端设备的能力恢复至正常能力(即传输速率提升至终端设备支持的最大传输速率)时,终端设备上报UEAssistanceInformation,并且OverheatingAssistance IE不包含相关信息,用于指示终端设备恢复到正常能力。
根据上述实施例二至实施例六所描述的示例,需要说明的是:
(1)本申请实施例中在降速过程中调整无线通信能力时,影响无线通信能力的各项参数可以具有优先级,在一个示例中,各项参数的优先级从大到小排序依次可以为:终端设备支持的能力等级(包括上行能力等级和下行能力等级)、终端设备支持的载波个数(包括上行载波个数和下行载波个数)、终端设备支持的BWP的大小、终端设备支持的MIMO能力、终端设备的BSR加权系数。升速过程可以理解为降速过程的逆过程,因此,在升速过程中调整无线通信能力时,各项参数的优先级从大到小排序依次可以为:终端设备的BSR加权系数、终端设备支持的MIMO能力、终端设备支持的载波个数(包括上行载波个数和下行载波个数)、终端设备支持的能力等级(包括上行能力等级和下行能力等级)。
应理解,上述仅为一种示例,在其它的实施例中,各项参数中部分参数的优先级也可以相同,比如,终端设备支持的能力等级(包括上行能力等级和下行能力等级)和终端设备支持的载波个数(包括上行载波个数和下行载波个数)的优先级可以相同,具体不做限定。
(2)一方面,在过热保护或过载保护中,对无线通信能力进行调整时,调整幅度较小,且会进行多次反复调整;而在节电保护中,对无线通信能力进行调整时,调整幅度可以较大,比如,降速过程中可以直接将终端设备的无线通信能力由最大无线通信能力降低为最小无线通信能力,相应地,升速过程中可以直接将终端设备的无线通信能力由最小无 线通信能力降低为最大无线通信能力。另一方面,在过热保护中,用于控制降速过程和升速过程的定时器的设定时间长度可以较长,比如可以设置为几分钟;在节电保护中,用于控制降速过程和升速过程的定时器的设定时间长度也可以较长,或者,在其它实施例中,节电保护中也可以无需定时器;而在过载保护中,用于控制降速过程和升速过程的定时器的设定时间长度可以较短,比如可以设置为1秒钟。由此可知,本申请实施例中,不同的场景在进行调整时的调整幅度可以不同、定时器的时长也可以不同(具体实施中,可由本领域技术人员根据实际需要进行灵活设置调整幅度和定时器的时长),也就是说,不同的场景可以对应不同的调整方式,比如,终端设备若确定是因为过热而导致需要启动调整过程,则可以按照过热保护对应的调整方式进行调整,若确定是因为过载而导致需要启动调整过程,则可以按照过载保护对应的调整方式进行调整,若确定是因为电池电量而导致需要启动调整过程,则可以按照节电保护对应的调整方式进行调整。
