Description

一种功率确定方法和装置
本申请要求于2018年8月10日提交中国专利局、申请号为201810912181.3、申请名称为“一种功率确定方法和装置”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
本申请涉及通信领域，尤其涉及一种功率确定方法和装置。
背景技术
双连接(dual connectivity，DC)通信系统是一种同时存在两个网络设备与终端设备进行通信的通信系统，相对于使用载波聚合的通信系统，DC通信系统的一个优点是允许不同网络设备对应的小区的系统时间不同步。
上述两个网络设备例如是主基站和辅基站，其中，主基站可以是长期演进(long term evolution，LTE)系统中的基站(eNB)，辅基站可以是新无线(new radio，NR)系统中的基站(gNB)，由于DC通信系统允许eNB和gNB各自对应的小区的系统时间不同步，并且NR有不同的numerology，与eNB和gNB组成DC通信系统的终端设备在传输过程中就可能存在传输时间重叠的问题，若上述终端设备在一个频带(band)内同时向eNB和gNB传输信息，则可能出会出现超出该终端设备的最大发射功率的情况，从而导致通信失败。
发明内容
本申请提供了一种功率确定方法和装置，可以避免该终端设备同时向两个接入设备发射信号时发射功率超出最大双连接发射功率的情况。
第一方面，提供了一种功率确定方法，包括：终端设备根据第一额外功率回退(additional maximum output power reduction，AMPR)确定第一NR功率，第一AMPR根据第一资源分配信息和NR调度信息计算得到，其中，终端设备通过LTE接入技术接入到第一接入设备，通过NR接入技术接入到第二接入设备；终端设备根据第二AMPR确定LTE功率，第二AMPR根据LTE调度信息和第二资源分配信息计算得到，第二资源分配信息为一个预设值；当第一NR功率与LTE功率之和大于终端设备的最大发射功率时，在全部或部分重叠的时域资源上，终端设备使用上述LTE功率向第一接入设备发送LTE信息，终端设备使用第二NR功率向第二接入设备发送信息或者终端设备不发送NR信息，第二NR功率小于第一NR功率。
终端设备通过预设的资源分配信息(即，第一资源分配信息)计算LTE功率，并通过预设的或者实时的资源分配信息计算第一NR功率，这样，在计算LTE功率时无需获取NR调度信息，从而可以在不违反通信协议(例如，协议38.213)的前提下避免因发射功 率超出该终端设备的最大发射功率导致通信失败。
可选地，上述方法还包括：当第一NR功率与LTE功率之和小于或等于终端设备的最大双连接发射功率时，在全部或部分重叠的时域资源上，终端设备使用第一NR功率向第二接入设备发送NR信息，终端设备使用LTE功率向第一接入设备发送LTE信息。
可选地，第一资源分配信息根据LTE调度信息获得或者第一资源分配信息为一个预设值。
例如，当终端设备在获取第一资源分配信息(即，计算NR侧的资源分配)时获取LTE调度信息失败，则终端设备可以根据预设的第一资源分配信息确定NR侧的资源分配，并根据NR侧的资源分配和AMPR计算出LTE功率，从而可以避免因发射功率超出该终端设备的最大发射功率导致通信失败。又例如，当终端设备在获取第一资源分配信息(即，计算NR侧的资源分配)获取LTE调度信息成功，则终端设备可以根据LTE调度信息获取第一资源分配信息，从而可以更加准确地计算出第一NR功率。
第二方面，本申请还提供了一种功率确定方法，包括：终端设备根据第三AMPR确定LTE功率，第三AMPR根据LTE调度信息和第三资源分配信息计算得到，其中，终端设备通过LTE接入技术接入到第一接入设备，通过NR接入技术接入到第二接入设备；终端设备采用LTE功率发送LTE信息。
根据上述方案，终端设备可以在计算LTE功率时获取第三资源分配信息，该第三资源分配信息用于指示NR侧的资源分配，可以是预设的值，也可以是实时获取的值，例如从NR调度信息获得的值，从而终端设备可以根据NR的资源分配计算LTE功率，避免因发射功率超出该终端设备的最大双连接发射功率导致通信失败。
可选地，第三资源分配信息根据NR调度信息获得，所述方法还包括：终端设备在第一时刻获取NR调度信息，第一时刻早于或等于预设的LTE功率的起始计算时刻。
若终端设备在LTE功率的起始计算时刻之前获取到NR调度信息，则终端设备可以根据该NR调度信息获取第三资源分配信息，并计算出LTE功率，若终端设备在LTE功率的起始计算时刻未获取到NR调度信息，则终端设备先根据预设的第三资源分配信息计算出LTE功率，此后，若终端设备在预设的LTE功率的起始更新时刻获取到NR调度信息，则终端设备根据该NR调度信息获取实时的NR调度信息，并重新计算出LTE功率，从而可以在确保LTE信息发送的前提下提高LTE功率计算的精度。
可选地，第三资源分配信息根据NR调度信息获得，所述方法还包括：终端设备在第二时刻获取NR调度信息，第二时刻晚于预设的LTE功率的起始计算时刻且不晚于预设的LTE功率的起始更新时刻，其中，终端设备在LTE功率的起始计算时刻基于LTE调度信息和预设值确定更新前的LTE功率。
若终端设备在LTE功率的起始计算时刻之前未获取到NR调度信息，则终端设备可以根据预设值和LTE调度信息计算AMPR值，并根据该AMPR值计算出更新前的LTE功率，此后，若终端设备在预设的LTE功率的起始更新时刻获取到NR调度信息，则终端设备根据该NR调度信息获取实时的第三资源分配信息，并重新计算出LTE功率，从而可以在确保LTE信息发送的前提下提高LTE功率计算的精度。
可选地，所述方法还包括：终端设备根据LTE调度信息生成功率余量报告(power headroom，PHR)，其中，所述第二时刻早于或等于预设的所述PHR的起始更新时刻， 终端设备在第二时刻之前基于更新前的LTE功率生成更新前的PHR；终端设备发送更新后的PHR。
更新前的LTE功率计算完成后，终端设备可以根据跟新前的LTE功率生成PHR，并上报该PHR，若终端设备获取NR调度信息的时刻不晚于预设的PHR起始更新时刻，则终端设备可以首先根据NR调度信息计算出更新后的LTE功率，再根据该更新后的LTE功率重新生成PHR，从而可以提高PHR的精度。
可选地，所述第三资源分配信息为预设值，终端设备采用基于该预设值确定的LTE功率发送LTE信息之前，所述方法还包括：终端设备在第三时刻获取NR调度信息，第三时刻晚于预设的LTE功率的起始计算时刻，并且，第三时刻晚于预设的LTE功率的起始更新时刻。
若终端设备在LTE功率的起始更新时刻之后获取到NR调度信息，则终端设备来不及更新LTE功率，可以按照基于预设的第三资源分配信息计算的LTE功率发射信号，从而可以保证LTE信息的正常传输。
第三方面，本申请提供了一种功率确定装置，该装置可以实现上述第一方面所涉及的方法中各个步骤所对应的功能，所述功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或软件包括一个或多个与上述功能相对应的单元或模块。
在一种可能的设计中，该装置包括处理器，该处理器被配置为支持该装置执行上述第一方面所涉及的方法中相应的功能。该装置还可以包括存储器，该存储器用于与处理器耦合，其保存该装置必要的程序指令和数据。可选地，该装置还包括通信接口，该通信接口用于支持该装置与其它网元之间的通信。
第四方面，本申请提供了一种计算机程序产品，所述计算机程序产品包括：计算机程序代码，当所述计算机程序代码被终端设备的通信单元、处理单元或收发器、处理器运行时，使得终端设备执行第一方面所述的方法。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1示出了一种适用于本申请的通信系统的示意图。如图1所示，该通信系统可以包括至少两个网络设备，例如图1中所示的网络设备110和120；该通信系统还可以包括至少一个终端设备，例如图1中所示的终端设备130。该终端设备130可以通过DC技术或者多连接技术与网络设备110和网络设备120建立无线链路。其中，网络设备110例如可以为主基站，网络设备120例如可以为辅基站。此情况下，网络设备110为终端设备130初始接入时的网络设备，负责与终端设备130之间的无线资源控制(radio resource control，RRC)通信，网络设备120可以是RRC重配置时添加的，用于提供额外的无线资源。
当然，网络设备120也可以为主基站，网络设备110也可以为辅基站，本申请对此不做限定。另外，图中仅为便于理解，示出了两个网络设备与终端设备之间无线连接的情形，但这不应对本申请所适用的场景构成任何限定。终端设备还可以与更多的网络设备建立无线链路。
各通信设备，如图1中的网络设备110、终端设备120和终端设备130，可以配置多个天线。该多个天线可以包括至少一个用于发送信号的发射天线和至少一个用于接收信号的接收天线。另外，各通信设备还附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。因此，网络设备与终端设备之间可通过多天线技术通信。
应理解，网络设备110或网络设备120可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved node B，或home node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR系统中的gNB或传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如BBU或分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议 (packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+CU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。
还应理解，终端设备130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、终端、无线通信设备、用户代理或用户装置。本申请的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、无人驾驶(self-driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。
图2示出了本申请提供的一种功率确定方法，包括：
S210，终端设备根据第一AMPR确定第一NR功率，第一AMPR根据第一资源分配信息和NR调度信息计算得到，其中，终端设备通过LTE接入技术接入到第一接入设备，通过NR接入技术接入到第二接入设备。
方法200中，终端设备为同时能够与第一接入设备和第二接入设备通信，第一接入设备例如是eNB，第二接入设备例如是gNB，因此，终端设备包含两个功能模块，即，LTE单元和NR单元，该两个功能模块可以通过软件实现，也可以通过硬件实现，本申请对此不作限定。
在本申请中，“第一”、“第二”仅用于区分说明，而不应被理解为对本申请的技术方案的限定，第一AMPR指的是基于AMPR机制确定的值，相应地，第二AMPR指的是根据AMPR机制确定的与第一AMPR相同或相异的值。带内(intraband)EN-DC(E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR)下的AMPR机制如下所述：
现有TS 38.101协议对intra-band EN-DC场景定义为资源分配占LTE和NR总的RB数的比重与AMPR值的拟合曲线为基础来定义intra-band EN-DC下的AMPR机制。
此外，方法200中的技术名词的含义如下：
LTE AMPR(例如，下述第二AMPR)：根据SIB消息、高层信令指示中的一个或多个和LTE的调度信息和NR的资源分配信息确定，NR资源分配信息可以根据NR调度信息获取的实际值，也可以是预设值，若NR资源分配信息是根据NR调度信息获取的实际值，则NR资源分配信息可以是NR传输实际用的资源块(Resource Block，RB)数；若NR资源分配信息是预设值，则NR资源分配信息可以是NR传输预设的资源块数，例如1RB。；
NR AMPR(例如，第一AMPR)：根据SIB消息、高层信令指示中的一个或多个和 NR的调度信息和LTE的资源分配信息确定，LTE资源分配信息可以是根据LTE调度信息获得的实际值，也可以是预设值，若LTE资源分配信息是根据LTE调度信息获得的实际值，则LTE资源分配信息可以是LTE传输实际用的资源块数；若LTE资源分配信息是预设值，则LTE资源分配信息可以是LTE传输预设的资源块数，例如1RB。；
LTE功率：根据LTE物理层信令和或高层信令指示的信息计算并考虑LTE AMPR的影响确定LTE功率，具体确定方法例如为：根据LTE物理层信令和或高层信令指示的信息计算得到第一LTE功率，与LTE侧最大发射功率Pcmax_LTE-AMPR作比较，如果第一LTE功率小于或等于Pcmax_LTE-AMPR，则第一LTE功率确定为LTE功率，如果第一LTE功率大于Pcmax_LTE-AMPR，则Pcmax_LTE-AMPR确定为LTE功率；
第一NR功率：根据NR物理层信令和或高层信令指示的信息计算并考虑NR AMPR的影响确定第一NR功率，具体确定方法例如为：根据NR物理层信令和或高层信令指示的信息计算得到第三NR功率，与NR侧最大发射功率Pcmax_NR-AMPR作比较，如果第三NR功率小于或等于Pcmax_NR-AMPR，则第三NR功率确定为第一NR功率，如果第三NR功率大于Pcmax_NR-AMPR，则Pcmax_NR-AMPR确定为第一NR功率；
最大双连接发射功率：在LTE和NR双连接场景中，限制LTE和NR传输的总功率的参数。
第二NR功率：若LTE功率和第一NR功率超过最大双连接发射功率，则终端设备会以第二NR功率进行传输，此时第二NR功率小于第一NR功率
全部或部分重叠的时域资源：由于LTE小区和NR小区可以是同步和异步，定时提前(Timing Advance，TA)也可以不同，此外，由于NR小区有不同的子载波间隔，例如，NR小区的子载波间隔为15*2 n kHz，因此NR小区时隙长度与LTE小区的时隙长度不同，这就导致LTE小区的上行传输和NR小区的上行传输会在时域上存在全部或部分重叠的情况
第一资源分配信息可以是预设的或者实时的LTE调度信息，用于指示LTE侧的资源分配情况，预设的LTE调度信息指的是终端设备中预先设定的值，实时的LTE调度信息指的是终端设备从eNB接收到的信息。
第一NR功率即终端设备向gNB发送NR信息时可能使用的功率。
S220，终端设备根据第二AMPR确定LTE功率，第二AMPR根据LTE调度信息和第二资源分配信息计算得到，第二资源分配信息为一个预设值且与第一资源分配信息相同或相异。
第二资源分配信息用于指示NR侧的资源分配情况，由于通信协议(38.213)定义终端设备中的LTE单元不能获取NR单元的信息，因此，终端设备在计算LTE功率时不能根据实时的NR调度信息确定gNB为NR单元分配的资源，终端设备需要根据预设的NR调度信息(即，第二资源分配信息)计算第二AMPR，并基于第二AMPR计算LTE功率。上述LTE功率指的是终端设备向eNB发送LTE信息时实际使用的功率。
S230，当第一NR功率与LTE功率之和大于终端设备的最大双连接发射功率时，在全部或部分重叠的时域资源上，终端设备使用上述LTE功率向第一接入设备发送LTE信息，终端设备使用第二NR功率向第二接入设备发送信息或者终端设备不发送NR信息，第二NR功率小于第一NR功率。
由于DC通信系统允许不同网络设备对应的小区的系统时间不同步，因此，eNB和gNB调度的时域资源可能部分或者全部重合，上述时域资源部分重合例如是eNB调度的子帧与gNB调度的传输时间间隔(transmission time interval，TTI)重合，上述时域资源全部重合例如是eNB调度的无线帧与gNB调度的无线帧的起始位置和终止位置相同。上述示例仅是举例说明，本申请所述的全部或部分重叠的时域资源不限于此。
在全部或部分重合的时域资源上，若第一NR功率与LTE功率之和大于终端设备的最大发射功率，则终端设备正常使用LTE功率发送LTE信息，并且，采用小于第一NR功率的第二NR功率发送NR信息，或者，放弃发送NR信息，从而避免了计算的发射功率大于最大发射功率导致通信失败。
上述LTE信息可以是向eNB发送的业务数据、信令和参考信号中的一种或多种，还可以是其它通过LTE接入技术传输的信息，上述NR信息可以是向gNB发送的业务数据、信令和参考信号中的一种或多种，还可以是其它通过NR接入技术传输的信息。
综上所述，终端设备通过预设的资源分配信息(即，第一资源分配信息)计算LTE功率，并通过预设的或者实时的资源分配信息计算第一NR功率，这样，在计算LTE功率时无需获取NR调度信息，从而可以在不违反通信协议(例如，协议38.213)的前提下避免因发射功率超出该终端设备的最大发射功率导致通信失败。
可选地，方法200还包括：当第一NR功率与LTE功率之和小于或等于终端设备的最大发射功率时，在全部或部分重叠的时域资源上，终端设备使用第一NR功率向第二接入设备发送NR信息，终端设备使用LTE功率向第一接入设备发送LTE信息。
在全部或部分重叠的时域资源上，若第一NR功率与LTE功率之和小于或等于终端设备的最大发射功率，则终端设备可以直接使用第一NR功率发送NR信息。
可选地，第一资源分配信息根据LTE调度信息获得或者第一资源分配信息为一个预设值。
例如，当终端设备在获取第一资源分配信息(即，计算NR侧的资源分配)时获取LTE调度信息失败，则终端设备可以根据预设的第一资源分配信息确定NR侧的资源分配，并根据NR侧的资源分配和AMPR计算出LTE功率，从而可以避免因发射功率超出该终端设备的最大发射功率导致通信失败。又例如，当终端设备在获取第一资源分配信息(即，计算NR侧的资源分配)获取LTE调度信息成功，则终端设备可以根据LTE调度信息获取第一资源分配信息，从而可以更加准确地计算出第一NR功率。
本申请还提供了另一种功率确定方法，如图3所示，方法300包括：
S310，终端设备根据第三AMPR确定LTE功率，第三AMPR根据LTE调度信息和第三资源分配信息计算得到，其中，终端设备通过LTE接入技术接入到第一接入设备，通过NR接入技术接入到第二接入设备。
S320，终端设备采用LTE功率发送LTE信息。
方法300中，第三AMPR为基于AMPR机制获得的值，第三AMPR可以是方法200中所述的LTE AMPR，第三资源分配信息可以是预设的或者实时的值，用于指示NR侧的资源分配情况，预设的NR调度信息指的是终端设备中预先设定的值，实时的值指的是终端设备根据从gNB接收到的NR调度信息获取的值。终端设备、第一接入设备以及第二接入设备的含义与方法200中相应的名词的含义相同，在此不再赘述。
在上述方案中，终端设备可以在计算LTE功率时获取第三资源分配信息，该第三资源分配信息用于指示NR侧的资源分配，从而可以根据NR的资源分配计算LTE功率，避免因发射功率超出该终端设备的最大发射功率导致通信失败。
可选地，第三资源分配信息根据NR调度信息获得，方法300还包括：
终端设备在第一时刻获取NR调度信息，第一时刻早于或等于预设的LTE功率的起始计算时刻。
若终端设备在LTE功率的起始计算时刻之前获取到NR调度信息，则终端设备可以根据该NR调度信息确定第三资源分配信息，并计算出LTE功率，若终端设备在LTE功率的起始计算时刻未获取到NR调度信息，则终端设备先根据预设的第三资源分配信息计算出LTE功率，此后，若终端设备在预设的LTE功率的起始更新时刻获取到NR调度信息，则终端设备根据该NR调度信息获取实时的第三资源分配信息，并重新计算出LTE功率，从而可以在确保LTE信息发送的前提下提高LTE功率计算的精度。
可选地，所述第三资源分配信息根据NR调度信息获得，方法300还包括：
终端设备在第二时刻获取NR调度信息，第二时刻晚于预设的LTE功率的起始计算时刻且不晚于预设的LTE功率的起始更新时刻，其中，终端设备在LTE功率的起始计算时刻基于LTE调度信息和预设值确定更新前的LTE功率。
若终端设备在LTE功率的起始计算时刻之前未获取到NR调度信息，则终端设备可以根据预设值和LTE调度信息计算AMPR值，并根据该AMPR值计算出更新前的LTE功率，此后，若终端设备在预设的LTE功率的起始更新时刻获取到NR调度信息，则终端设备根据该NR调度信息获取实时的第三资源分配信息，并重新计算出LTE功率，从而可以在确保LTE信息发送的前提下提高LTE功率计算的精度。
可选地，方法300还包括：终端设备根据LTE调度信息和第三资源分配信息生成功率余量报告(power headroom，PHR)，其中，所述第二时刻早于或等于预设的所述PHR的起始更新时刻，终端设备在第二时刻之前基于更新前的LTE功率生成更新前的PHR；终端设备发送更新后的PHR。
更新前的LTE功率计算完成后，终端设备可以根据该LTE功率生成更新前的PHR，若终端设备获取NR调度信息的时刻不晚于预设的PHR起始更新时刻，则终端设备可以首先根据NR调度信息计算出实时的第三AMPR，并根据实时的第三AMPR计算得到更新后的LTE功率，再根据该更新后的LTE功率生成更新后的PHR，从而可以提高PHR的精度。
需要说明的是，PHR的起始更新时刻与LTE功率的起始更新时刻可以相同，也可以相异。
可选地，所述第一资源分配信息为预设值，在S320之前，方法300还包括：
终端设备在第三时刻获取NR调度信息，第三时刻晚于预设的LTE功率的起始计算时刻，并且，第三时刻晚于预设的LTE功率的起始更新时刻。
若终端设备在LTE功率的起始更新时刻之后获取到NR调度信息，则终端设备来不及更新LTE功率，可以按照基于预设的第二资源分配信息计算的LTE功率发射信号，从而可以保证LTE信息的正常传输。
图4示出了本申请提供的再一种功率确定方法。如图4所示，eNB和gNB分别通过 物理下行控制信道(physical downlink control channel，PDCCH)调度终端设备上行传输，eNB和gNB调度的时域资源(所示的子帧)完全重合，终端设备的LTE单元在子帧N(N为大于或等于0的整数)向NR单元发送LTE调度信息，以便于NR单元计算AMPR值，并根据该AMPR值计算NR发射功率。终端设备的NR单元在子帧N+1向LTE单元发送NR调度信息，以便于LTE单元计算AMPR值，并根据该AMPR值计算LTE发射功率。由于LTE单元在LTE发射功率的起始计算时刻之前获取到NR调度信息，因此，LTE单元可以根据实时的NR调度信息计算LTE发射功率，随后，根据该LTE发射功率生成PHR并上报该PHR。
图5示出了本申请提供的再一种功率确定方法。如图5所示，eNB和gNB分别通过PDCCH调度终端设备上行传输，eNB和gNB调度的时域资源(所示的子帧)完全重合，终端设备的LTE单元在子帧N(N为大于或等于0的整数)向NR单元发送LTE调度信息，以便于NR单元计算AMPR值，并根据该AMPR值计算NR发射功率。
终端设备的NR单元在子帧N+2向LTE单元发送NR调度信息，以便于LTE单元计算AMPR值。由于LTE单元在LTE发射功率的起始计算时刻之前未获取到NR调度信息，因此，LTE单元可以根据预设的NR调度信息(也可称为预设的资源分配信息)计算LTE发射功率，随后，LTE单元在子帧N+2获取到NR调度信息，由于子帧N+2在LTE单元的LTE发射功率起始更新时刻之前，因此，LTE单元还来得及重新计算LTE功率，因此，LTE单元可以根据实时的NR调度信息(即，在子帧N+2获得的NR调度信息)计算AMPR值，并根据该AMPR值计算更为准确的LTE功率，随后按照更新后的LTE功率在子帧N+4上传输。
由于PHR需要根据LTE功率生成，因此，PHR的计算时间晚于LTE功率的时间，并且，PHR的更新时间晚于LTE功率的更新时间，为了能够更新PHR，需要提早获取NR调度信息，在本申请中，PHR更新起始时刻指的是更新PHR所需要的获取NR调度信息的最晚时刻，也就是说，若获取NR调度信息的时刻早于PHR更新起始时刻，则终端设备可以基于该NR调度信息更新PHR，若获取NR调度信息的时刻晚于PHR更新起始时刻，则终端设备可能来得及更新LTE功率，但来不及更新PHR。
若LTE单元获取NR调度信息的时刻晚于LTE功率的起始计算时刻，则LTE单元根据预设的NR调度信息计算LTE功率，并基于该LTE功率生成PHR。随后，LTE单元在LTE功率的起始更新时刻前(例如，第一时刻)获取到实时的NR调度信息，若该第一时刻早于更新PHR所要求的获取NR调度信息的时刻(即，PHR更新时刻)，则LTE单元更新并上报PHR，若该第一时刻晚于PHR更新时刻，则LTE单元不再更新PHR，而是上报前一次生成的PHR，以保证eNB的正常调度。
图6示出了本申请提供的再一种功率确定方法。如图6所示，eNB和gNB分别通过PDCCH调度终端设备上行传输，eNB和gNB调度的时域资源(所示的子帧)部分重合，终端设备的LTE单元在子帧N(N为大于或等于0的整数)向NR单元发送LTE调度信息，以便于NR单元计算AMPR值，并根据该AMPR值计算NR发射功率。
终端设备的NR单元在子帧N+4向LTE单元发送NR调度信息，以便于LTE单元计算AMPR值。由于LTE单元在LTE发射功率的起始计算时刻之前未获取到NR调度信息，因此，LTE单元可以根据预设的NR调度信息(也可称为预设的资源分配信息)计算LTE 发射功率，随后，LTE单元在子帧N+4获取到NR调度信息，由于子帧N+4在LTE单元的LTE发射功率起始更新时刻之后，因此，LTE单元来不及重新计算LTE功率，因此，LTE单元可以根据之前计算的LTE功率发送LTE信息，随后按照该LTE功率生成并上报PHR。
