低功耗模式下的UE的跟踪处理方法和设备 技术领域
本申请实施例涉及通信技术，尤其涉及一种低功耗模式下的用户设备(英文：User Equipment，简称：UE)的跟踪处理方法和设备。
背景技术
未来通信***需要支持海量用户接入，并且这些海量用户常具有不频繁的小包数据业务。每当这些不频繁的小包数据到达时，如果按照长期演进(英文：Long Term Evolution，简称：LTE)或者先进的长期演进(英文：Long Term Evolution-Advanced，简称：LTE-A)的机制，用户设备(英文：User Equipment，简称：UE)无线资源控制从IDLE状态(即空闲状态)重新激活CONNECTED状态(即连接状态)，需要先建立控制面连接(C-plane)，再建立数据面连接(U-plane)，从而带来大量的信令/信息交互开销以及数据传输延迟。
为了解决这个问题提出第三种UE状态，即节能模式(英文：Energy Conserved Operation，简称：ECO)状态，也称为低功耗模式。在这种状态下，UE与网络之间保留原有的无线资源控制(英文：Radio Resource Control，简称：RRC)上下文。当处于ECO状态下的UE有上行业务时，UE直接采用grant-free的方式发送，即不用激活UE到CONNECTED状态，不发起RRC建立连接的过程，因此不进行任何网络命令授权，直接在预定义的资源上发送数据。虽然ECO状态是一种节能模式，UE应该尽量减少信令开销以及减少开启接收和发送信号的次数。但是UE的上行数据，在采用grant-free的方式发送时，到达发送/接收点(英文：Transmission/reception point，简称：TRP)的定时(Timing)可能会随着时间和地点的变化而改变，比如：移动中的UE，其与TRP的传播延迟会不断变。
在现有LTE/LTE-A***的随机接入过程中，演进型基站(英文：Evolved Node Base Station，简称：eNodeB)通过测量接收到的上行前导码(preamble)来确定定时提前(英文：timing advance，简称：TA)值，并通过随机接入响应(英文名称：Random Access Response，简称RAR)的介质访问控制(英文：Media Access Control，简称：MAC)payload携带定时提前命令(英文：Timing Advance Command，简称：TAC)(共11bits)发送给UE，表征该UE的定时调整值，该过程被称为“初始上行同步过程”。当UE处于RRC_CONNECTED状态时，eNodeB基于测量对应UE的上行传输来确定每个UE的TA值。因此，只要UE有上行传输，eNodeB就可以用来估计TA值。理论上，UE发送的任何信号都可用于测量TA值。如果某个特定UE需要矫正，则eNodeB会发送一个TAC(6bit)给该UE，要求其调整上行传输定时。这个过程被称为“上行同步更新过程”。
然而，在上述的“初始上行同步过程”中定时调整方法在随机接入过程中使用，它包含繁琐的接入步骤，而且eNodeB下发的MAC层信令RAR，除了携带TAC以外，还携带随机接入过程中的无线网络临时标识(英文：Radio Network Tempory Identity，简称： RNTI)和上行指配信息。在上述的“上行同步更新过程”中，网络侧随时会发送TAC给UE，UE需要检测每个调度单元的控制信道。因而，上述的UE获取TA值的方式，信令开销大，不适合ECO状态的定时提前量调整。
发明内容

具体实施方式
图1为本申请技术方案涉及的一种无线通信***的架构示意图，如图1所示，本申请提供的低功耗模式下的UE的跟踪处理方法主要应用在该***中，用于对ECO态的终端更新上行TA的过程，以获得上行时间同步保证可靠的上行传输。考虑空口传输，在***架构图中，本申请涉及的网元主要是网络设备和用户设备，也称为终端设备(例如：用户侧的手机，平板电脑等)，该网络设备可以是网络侧设备，例如基站，也可以为具有基站类似功能的其它网络侧设备，还可以是终端，例如，在设备到设备(英文：Device-to-Device，简称：D2D)通信中，由作为发射机的终端承担网络设备的角色。

具体实现中，网络设备和用户设备都包括：
发送器和接收器，实现无线收发功能；
处理器，也称为数据处理器，包括调制编码器等用于实现发送数据处理，解调译码器等用于实现接收数据处理。
图2为本申请低功耗模式下的UE的跟踪处理方法实施例一的流程图，如图2所示， 在上述图1所示的***架构下，该低功耗模式下的UE的跟踪处理方法的具体实现步骤为：
S101：UE获取与网络设备之间的传输配置信息。
在本步骤中，UE，也称为终端，需要在UE连接状态下获取发送上行跟踪信号的传输配置信息，该传输配置信息指示将上行跟踪信号的发送模式配置为：非连续发送模式，即该上行跟踪信号按照发送周期采用非连续发送模式进行发送，且所述传输配置信息包括发送周期。
在该方案中，UE获取到的传输配置信息中的发送周期可以是固定的周期，也可以是可根据配置的规律变化的变周期，即在后续的UE的跟踪处理过程中，UE可以重新获取传输配置信息以调整该发送周期，也可以是预先配置的变周期规律，根据该规律改变该发送周期。
可选的，UE获取传输配置信息的一种具体方式为接收网络设备发送的传输配置信息，即该网络设备向UE发送传输配置信息。具体实现中，UE接收网络设备发送的所述传输配置信息至少包括以下两种实现方式：
第一种实现方式：UE接收网络设备发送的无线资源控制信息；无线资源控制信息包括所述传输配置信息。
其含义是网络设备向UE发送无线资源控制信息，在该无线资源控制信息中携带上述传输配置信息，即在UE初始接入过程中网络设备就将传输配置信息发送给UE
第二种实现方式，UE接收网络设备的***广播消息，***广播消息包括所述传输配置信息。
其含义是网络设备通过***广播消息发送传输配置信息，该***广播消息中可以包括多个UE的传输配置信息。
S102：当UE进入低功耗模式时，UE根据传输配置信息向网络设备发送上行跟踪信号。
在完成上述配置之后，当UE进入了低功耗模式，也就是ECO模式之后，UE可以根据传输配置信息中的发送周期，向网络设备发送上行跟踪信号，网络设备接收该UE根据传输配置信息发送的上行跟踪信号。
S103：网络设备根据上行跟踪信号，确定UE的定时提前TA调整信息。
在本步骤中，网络设备对该上行跟踪信号进行测量，得到该UE的TA调整信息。
可选的，该步骤中的网络设备可以是UE发送上行跟踪信号的前述的网络设备，也可以是其他的网络设备，即对上行跟踪信号进行检测得到TA调整信息的过程可以是其他设备执行。
S104：UE接收网络设备返回的TA调整信息。
在本步骤中，网络设备在检测到TA调整信息之后，将该TA调整信息返回给UE，UE接收到网络设备返回的TA调整信息，该TA调整信息用来调整发送上行信号的时刻。
在该方案中，根据上行跟踪信号检测得到TA调整信息的网络设备可以是UE发送上行跟踪信号的网络设备，也可以是其他网络设备，其他网络设备根据该上行跟踪信号检测得到TA调整信息之后发送给上述网络设备，再由上述网络设备将该TA调整信息返回UE。
本实施例提供的低功耗模式下的UE的跟踪处理方法，提出专用于UE跟踪处理的上行跟踪信号，并对UE发送上行跟踪信号的周期和发送模式进行配置，UE在进入低功耗模式之后，采用非连续发送模式，按照传输配置消息中的发送周期向网络设备发送上行跟踪信号，网络设备根据该上行跟踪信号得到该UE的TA调整信息，并返回给UE，以供UE调整上行发送时刻。通过配置周期性的向网络设备发送用于UE跟踪的上行跟踪信号，网络设备接收到该上行跟踪信号之后才向UE返回TA调整信息，减少UE和网络设备之间的信令开销，更适合低功耗模式下对UE进行跟踪。
图3为本申请低功耗模式下的UE的跟踪处理方法实施例二的流程图，如图3所示，在上述实施例一的基础上，步骤S102中的UE根据所述传输配置信息向所述网络设备发送上行跟踪信号的具体实现步骤为：
S201：UE根据发送周期，确定发送上行跟踪信号的第一无线帧的位置和在第一无线帧中的第一调度单元位置。
在本步骤中，UE根据传输配置信息发送上行跟踪信号的具体实现中首先需要根据发送周期确定第一无线帧的位置，这里的第一无线帧的位置指的是该第一无线帧的时序位置，或者第一无线帧的帧号，能够表征该第一无线帧在哪个时刻发送即可，另外还需要获取发送该上行跟踪信号时在该第一无线帧中的具***置，即第一调度单元位置。
S202：UE在第一无线帧中的第一调度单元位置向网络设备发送上行跟踪信号。
在本步骤中，UE确定出第一无线帧和在第一无线帧中的第一调度单元位置之后，在该第一调度单元位置上向网络设备发送上行跟踪信号。
对于网络设备，网络设备根据发送周期，获取UE发送上行跟踪信号的第一无线帧的位置和在所述第一无线帧中的第一调度单元位置，然后在该第一无线帧中的第一调度单元位置接收UE发送的上行跟踪信号。
后续再对该上行跟踪信号进行检测处理，得到该UE的TA调整信息，并返回给UE，以使UE根据该TA调整信息调整上行发送时刻，并可以在调整之后进行上行信号的发送。
在上述任一实施例的基础上，传输配置信息还用于指示所述UE的接收模式为非连续接收模式，所述传输配置信息还包括接收周期。这里的接收模式指的是UE接收TA调整信息的时候可以是非连续接收模式，并同时配置UE接收TA调整信息的接收周期，与前述发送周期类似的，该接收周期可以是配置的固定周期，也可以是根据一定规律的可变周期。
同样的，网络设备的配置的过程都是针对UE的，但网络设备侧也要相应的有这些配置，用以配合UE侧的行为。
在任一实现方式中，与发送上行跟踪信号类似，UE接收网络设备返回的定时提前TA调整信息也需要根据接收周期获取接收所述TA调整信息的第二无线帧的位置和在所述第二无线帧中的第二调度单元位置；然后在所述第二无线帧中的第二调度单元位置，接收所述网络设备发送的所述TA调整信息。
对于网络设备来说，网络设备需要根据接收周期确定所述UE接收TA调整信息的第二无线帧的位置和在第二无线帧中的第二调度单元位置；然后在所述第二无线帧中的第二调度单元位置向所述UE发送所述TA调整信息。
本实施例提供的低功耗模式下的UE的跟踪处理方法，提出专用于UE跟踪处理的上行跟踪信号，并对UE发送上行跟踪信号的周期和发送模式、UE接收TA调整信息的接收周期和接收模式进行配置，UE在进入低功耗模式之后，采用非连续发送模式，按照传输配置消息中的发送周期向网络设备发送上行跟踪信号，网络设备根据该上行跟踪信号得到该UE的TA调整信息，并返回给UE，UE根据接收周期以非连续接收模式接收该TA调整信息，以供UE调整上行发送时刻。通过配置周期性的向网络设备发送用于UE跟踪的上行跟踪信号，网络设备接收到该上行跟踪信号之后才向UE返回TA调整信息，UE根据接收周期接收TA调整信息，大幅减小UE和网络设备之间的信令开销，更适合低功耗模式下对UE进行跟踪。
在上述实施例的基础上，当UE完成初始接入过程后，UE已获取TA信息；然后UE根据网络指示或由UE端定时器触发进入ECO状态。在ECO状态，UE根据网络配置或上层配置的传输配置信息获取发送上行跟踪信号的参数，如根据发送周期等获得发送上行跟踪信号的无线帧位置和在无线帧中的调度单元位置并发送上行跟踪信号。网络侧根据对上行跟踪信号的测量执行服务发送/接收点(英文：Transmission/reception point，简称：TRP)的选择、UE定位、移动性处理、上行TA测量等操作。
下面对本申请提出的低功耗模式下的UE的跟踪处理方法的具体实现过程进行详细说明。
图4为本申请移动的UE的跟踪机制示意图，如图4所示，在UE随机接入/连接状态的过程中，网络设备给UE配置非连续传输(英文：Discontinuous transmission，简称：DTX)模式，并配置发送周期等参数，在UE进入ECO模式后，UE通过配置参数可以获得发送上行跟踪(UL Tracking)信号的第一无线帧(TrFi)的位置(可以使用无线帧号表示)和该第一无线帧里的第一调度单元位置(TrOj)，UE在配置的第一无线帧和第一调度单元位置发送上行跟踪信号。从{TrFi，TrOj}到{TrFi+1，TrOj}是一个上行发送周期，也称为上行跟踪周期(Tracking Cycle)，这个上行的发送周期可以配置为500个无线帧，或1000个无线帧等。UE在(TrFi，TrOj)的位置，开启发射机发送上行跟踪信号，发送完毕后关掉发射机进入睡眠状态。
另外，如果网络设备检测到TA需要调整，则还会增加发送TA调整信息给UE，对于该TA调整信息的发送周期也可以配置。
网络除了给UE的上行跟踪信号配置DTX模式以外，还需要给UE配置接收TA消息的反馈接收模式为非连续反馈(英文：Discontinuous feedback，简称：DFB)，即将UE接收TA调整信息的接收模式配置为非连续接收模式(英文：Discontinuous reception，简称：DRX)，用于UE接收TA调整信息。网络配置DFB或者UE的DRX通过配置UE的接收周期等参数实现，UE通过配置参数可以获得接收TA调整信息的参数，如第二无线帧和该第二无线帧里的第二调度单元位置{TAFi，TAOj}。UE只在{TAFi，TAOj}的位置醒来，开启接收机检测是否有发给自己的TA调整信息，如图4所示，检测完毕后关掉接收机进入睡眠状态。
图5为移动速度较小或者静止的UE的跟踪机制示意图，如图5所示，对于静态UEs或慢速移动UEs，当UE完成初始接入过程，UE已获取TA信息；然后进入ECO状态，由于UE位置长期不变，服务TRP的选择、UE定位、移动性处理等操作基本不会执行； 而且UE的TA也基本不用调整，如果由于长时间累计的晶振偏移，可以通过检测多次下行信号的到达时间差，UE自己判断后在上行传输时对上行发送信号的时间点做适当调整，属于实现问题。在这种场景，网络配置的发送上行跟踪信号的周期会很长，或配置为无穷大，即不发。
由于不是每次发送上行跟踪信号都会检测到TA需要更新，特别是对移动速率不是很大或者基本静止的UE来说，TA的调整周期可以很长，因此TA调整的周期，也即上述的接收周期可以配置为大于或者等于发送上行跟踪信号的发送周期，即TACyc≧TrCyc。特别是对于静止的UE，接收周期可以远大于上行跟踪信号的发送周期。
即当UE的移动速度小于预设速度阈值时，所述接收周期大于或等于所述发送周期。该方案中，UE的移动速度小于预设速度阈值包括UE的移动速度比较小，以及UE静止两种情况，UE静止或者移动速度较小的情况下，TA调整周期可以很长，因此可以配置接收周期大于发送周期。
网络设备(图4和图5中的eNB)根据上行信号，计算TA量，在{TAFi，TAOj}的位置按需发送TA调整信息，UE在该位置检测下行信道，如果检测到TA调整信息，则UE根据新的TA调整信息(该TA调整信息中包括定时提前命令)更新上行发送时刻；如果UE在该位置，没有检测到TA调整信息，则UE认为上行发送时刻不用调整。UE使用最新的上行发送实际确定下一次上行传输时的提前定时量。
图6为多个UE的跟踪机制示意图，如图6所示，对于多个UE，网络设备需要对每个UE的传输配置信息进行配置，并发送给不同的UE。
多个ECO态的UE执行上行测量时，需要根据UE移动速度等配置不同的发送周期和接收周期等参数，网络设备判断UE移动速度可以使用如下一种或几种实现方式：
1)、网络设备根据UE上报的业务属性或者UE特性确定UE的移动速度。
该种实现方式的含义是：网络可以根据UE初始接入时上报的UE特性或业务属性直接或间接判断该UE是移动终端或是静止终端，如由UE属性为某类传感器可以直接判断该UE为基本静止终端，也可以检测出该UE的移动速度。
2)、网络设备根据多普勒测量获取所述UE的移动速度。
即网络则也可以根据多普勒测量等判断该UE的移动速度。
3)、网络设备根据UE上报的下行参考信号的能量测量信息，获取UE的移动速度。
网络则还可以根据UE对下行参考信号的能量测量上报判断UE的移动速度。
网络设备需要确定UE的移动速度，确定UE是否静止或者几乎静止，若是则可配置将接收周期大于发送周期。
UE根据网络设备配置的传输配置信息中的发送周期和接收周期等参数获取DTX和DFB参数，不同UE可以有相同的跟踪参数，如具有相同的发送和接收无线帧及无线帧里的调度单元，也可以具有相同的无线帧但不同的无线帧里的调度单元，如图6所示，UE1的跟踪参数为{TrF1，TrO1}，UE2的跟踪参数为{TrF1，TrO2}，即UE1和UE2具有相同的发送上行跟踪信号的无线帧，但在无线帧里的调度单元不同。
当UE上下行分别接入不同的网络设备中，上行接入的网络设备和下行接入的网络设备间可以通过X2接***互该UE对应的控制信息、TA信息等信息，因此这里对上行接入的网络设备和下行接入的网络设备不作区分，不再赘述。
在上述任一方案中，对DTX和DFB的配置可以通过***消息进行广播或通过无线资源控制信息配置实现，如新增消息体：
DTX_Config{
DTXCycle ENUMERATED{rf128,rf256,rf512,rf1024,rf2048,rf4096,rf8192,rfinfinity},
nB ENUMERATED{fourT,twoT,oneT,halfT,quarterT,oneEighthT,oneSixteenthT,oneThirtySecondT}
}
UE可以使用同寻呼消息的发送无线帧和无线子帧获取方法，获得发送上行跟踪(UL tracking)信号的无线帧和无线帧里的调度单元。其中DTXCycle和nB的用法同寻呼配置中defaultPagingCycle和nB的用法，标准中有详细定义，在此不再赘述。
对DFB的配置可以结合网络对DTX的配置获取，如新增消息体：
Figure PCTCN2017091288-appb-000001
DFBCycle定义的不是绝对值，而是相对DTXCycle的倍数，如DTXCycle配置为128个帧时，DFBCycle配置为1表示UE每次发送完上行跟踪信号后都会收到TAC反馈，DFBCycle配置为2表示UE每发送2次上行跟踪信号后会收到TAC反馈。Sf配置了TAC反馈的调度单元与发送上行跟踪信号的调度单元之间间隔的子帧数，可以根据网络处理能力及传输能力配置。
按照上述方式配置完成后，将得到的传输配置信息通过***广播消息或者无线资源控制信息发送给各个UE，以使UE根据对应的发送周期发送上行跟踪信号。
在上述任一种实现方式中，UE根据接收周期接收TA调整信息，即在第二无线帧中的第二调度单元位置，接收网络设备发送的TA调整信息的具体实现方式包括以下几种：
第一种实现方式，在第二无线帧中的第二调度单元位置接收网络设备通过下行控制信道发送的TA调整信息。
该方案的含义是，该TA调整信息可以通过下行控制信息承载，即增加一条新的下行控制信息(英文：Downlink Control Information，简称：DCI)指示UE的TA调整信息。UE在每个{TAFi，TAOj}的位置监测DCI，读取TA调整信息。这个TA调整信息可以按需发送，但是由下行控制信息承载。即网络设备在第二无线帧中的第二调度单元位置通过下行物理控制信道向UE发送TA调整信息。
第二种实现方式，UE在第二无线帧中的第二调度单元位置接收网络设备通过下行共享信道发送的TA调整信息。
该方式的含义是：该TA调整信息可以通过数据包承载。网络设备在第二无线帧中的第二调度单元位置通过下行共享信道向UE发送TA调整信息。
第三种实现方式，将物理层DCI信令与数据包相结合的方案承载TA调整信息。由数据包承载的TA调整信息可以指示精度较粗的TA调整，调整范围可以比较大；而由物理层DCI信令承载的TA命令可以指示更加精细的TA调整。UE会根据两个信令中的TA 调整信息组合来调整上行发送的TA。即UE接收的TA调整信息的具体方式包括：通过下行控制信息承载TA调整信息，或者通过数据包由下行共享信道承载该TA调整信息，也可以是通过将物理层下行控制信令和数据包消息结合的方式来承载TA调整信息。
需要说明的是，对应于相同{TrFi，TrOj}位置上发送上行跟踪信号的一组UEs可以在同一{TAFi，TAOj}位置上监测TA调整信息反馈。对于三种实现方式，TA调整信息的反馈可以是基于UE粒度的，即每个下行控制信息或/和数据包中指示一个UE的TA调整信息；也可以将一组UEs的TA调整信息复用组合在一个下行控制信息或数据包中一起发送。在UE粒度的反馈中，可以用UE标识来识别发送给该UE的TA调整信息；在复用组合的反馈中，可以用公共标识，如TA-RNTI来识别TA调整信息，此时所有UE使用相同的TA-RNTI，但不同的UE可以通过消息中UE的标识识别发送给自己的TA调整信息。通过一组UEs共用一条下行控制信息或/和数据包，资源开销较小。
本申请提出ECO模式下的UE的跟踪处理方法提供了至少两种省电的用户设备跟踪方式。UE按照非连续发送模式发送上行跟踪信号，网络设备按需反馈TA调整信息，通过引入非连续发送和非连续接收模式，不但可以节省UE和网络设备间的信令开销，还可能够为UE省电，即UE在实现节能目标的同时，还能保持与***的上行同步。
