具体实施方式
下面结合附图，对本申请提供的实施例做详细说明。本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，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。
图1示出了本申请的一种可能的系统网络示意图。如图1所示，至少一个终端10与无线接入网(radio access network,RAN)进行通信。所述RAN包括至少一个网络设备20，为清楚起见，图中只示出一个网络设备和一个用户设备UE。所述RAN与核心网络(core  network，CN)相连。可选的，所述CN可以耦合到一个或者更多的外部网络(external network)，例如英特网，公共交换电话网(public switched telephone network，PSTN)等。
为便于理解下面对本申请中涉及到的一些名词做些说明。
本申请中，名词“网络”和“系统”经常交替使用，但本领域的技术人员可以理解其含义。用户设备(user equipment，UE)是一种具有通信功能的终端设备，也可以称为终端，可以包括具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备等。在不同的网络中用户设备可以叫做不同的名称，例如：终端，移动台，用户单元，站台，蜂窝电话，个人数字助理，无线调制解调器，无线通信设备，手持设备，膝上型电脑，无绳电话，无线本地环路台等。为描述方便，本申请中简称为用户设备UE或终端。网络设备可以是基站(base station，BS)、云网络中的无线接入设备或中继站等具有无线收发功能的设备。基站也可称为基站设备，是一种部署在无线接入网用以提供无线通信功能的设备。在不同的无线接入系统中基站的名称可能有所不同，例如在而在通用移动通讯系统(universal mobile telecommunications System，UMTS)网络中基站称为节点B(NodeB),在LTE网络中的基站称为演进的节点B(evolved nodeB，eNB或者eNodeB)，在未来5G系统中可以称为收发节点(transmission reception point，TRP)网络节点或g节点B(g-NodeB，gNB)。
当网络设备20为终端10配置的多个成员载波中至少两个成员载波的子载波间隔不相同时，需要解决的一个问题为：终端10如何使用这多个成员载波进行上行传输。更具体，终端10如何使用这多个成员载波进行上行传输，同时可以使得各个成员载波的功率能够保证各个成员载波上承载的信道、信号或业务的传输满足需求。
针对此问题，本申请提出了新的通信方法、网络设备和终端。
图2是本申请一个实施例的通信方法的示意性流程图。应理解，图2示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图2中的各个操作的变形。
S210，终端使用第一成员载波发送第一信息、第二信息和第三信息，第一成员载波为网络设备给终端配置的多个成员载波中的一个，第一信息包括第一成员载波的功率余量，第二信息指示所述终端的发送功率是否等于所述终端的最大可用发送功率，第三信息指示终端的最大可用发送功率与第二成员载波的发送功率的差值，第一成员载波的子载波间隔大于第二成员载波的子载波间隔。
相应地，网络设备接收终端使用第一成员载波发送的第一信息、第二信息和第三信息，
本申请实施例中，网络设备可以为终端配置多个成员载波。
如网络设备与终端在NR系统的载波聚合模式下通信时，网络设备可以为终端配置NR系统中子载波间隔为15*2 n kHz的多个成员载波，且这多个成员载波中至少两个成员载波的子载波间隔不同。此时，第一成员载波的子载波间隔的一个示例为120kHz，第二成员载波的子载波间隔的一个示例为15kHz。
如，网络设备与终端之间在LTE系统与NR系统间双连接的模式下通信时，网络设备可以为终端配置LTE系统中子载波间隔为15kHz的成员，同时，为终端配置NR系统中子载波间隔为15*2 n kHz的成员载波，n为正整数。该模式下，第一成员载波的子载波间隔的一个示例为120kHz，第二成员载波的子载波间隔一个示例为15kHz。
又如，网络设备与终端之间在NR系统内双连接的模式下通信时，网络设备可以为终端配置NR系统中子载波间隔为15*2 n kHz的多个成员载波，且这多个成员载波中至少两个成员载波的子载波间隔不同。此时，第一成员载波的子载波间隔的一个示例为120kHz，第二成员载波的子载波间隔的一个示例为15kHz。
网络设备为终端配置多个成员载波后，终端可以使用这多个成员载波中子载波间隔较大的第一成员载波，在第一成员载波对应的时隙中向网络设备发送第一信息、第二信息和第三信息。相应地，网络设备在第一成员载波对应的时隙中接收终端使用第一成员载波发送的第一信息、第二信息和第三信息。
第一信息包括第一成员载波的功率余量，可以理解为：第一信息包括第一成员载波在当前时隙中的功率余量。第一信息具体可以是第一成员载波的功率余量上报(power headroom report，PHR)信息。
第二信息指示终端的发送功率是否等于终端的最大可用发送功率，也可以理解为：第二信息指示终端当前的发送功率是否超过了终端的最大可用发送功率，或者可以理解为：第二信息指示终端当前是否使用了最大可以发送功率。
第二信息具体可以包含一个比特，即通过一个比特指示终端的发送功率是否等于终端的最大可用发送功率。如第二信息为“1”时，可以指示终端的发送功率等于终端的最大可用发送功率，第二信息为“0”时，可以指示终端的发送功率不等于终端的最大可用发送功率。
应理解，网络设备与终端在NR系统的载波聚合模式下通信时，终端的发送功率可以指终端当前的实际发送功率。换句话说，终端的发送功率可以指终端当前使用所有成员载波进行上行传输的实际功率。或者说，终端的发送功率可以指网络设备为终端配置的所有成员载波当前进行上行传输的发送功率之和。
网络设备与终端之间在LTE系统与NR系统间双连接的模式下通信时，或网络设备与终端之间在NR系统内双连接的模式下通信时，网络设备为终端配置的多个成员载波可以分为多个载波组(carrier group，CG)。此时，第一成员载波与第二成员载波可以属于同一个载波组，终端的发送功率可以指该载波组的实际发送功率。换句话说，终端的发送功率可以指第一成员载波和第二成员载波所属的载波组中所有成员载波当前进行上行传输的实际功率。或者说，终端的发送功率可以指第一成员载波和第二成员载波所属的载波组中所有成员载波当前进行上行传输的发送功率之和。
本申请的实施例中，载波组也可以称为小区组(cell group，CG)。
应理解，网络设备与终端在NR系统的载波聚合模式下通信时，终端的最大可用发送功率可以由终端的能力决定。同一上行传输时间，终端的实际发送功率不能超过终端的最大可用发送功率。
网络设备与终端之间在LTE系统与NR系统间双连接的模式下通信时，或网络设备与终端之间在NR系统内双连接的模式下通信时，即网络设备为终端配置的多个成员载波可以分为多个载波组时，终端的最大可用发送功率可以为第一成员载波与第二成员载波所属载波组的最大可用发送功率。同一上行传输时间，第一成员载波与第二成员载波所属载波组中所有成员载波的实际发送功率不能超过终端的最大可用发送功率。
第三信息也可以理解为：指示第一成员载波后续时隙中的上行功率的可调范围。
第三信息具体为：终端的最大可用发送功率-第二成员载波的发送功率。其中，第二成员载波的发送功率为第二成员载波当前的实际上行发送功率。
S220，网络设备根据第一信息、第二信息和第三信息调度终端的上行传输，其中，第一成员载波的上行发送功率不超过终端的最大可用发送功率与第二成员载波的发送功率的差值。
网络设备接收到终端使用第一成员载波发送的第一信息、第二信息和第三信息后，可以根据这三个信息对终端的上行传输进行调度，从而使得终端进行上行传输时，各个成员载波的功率能够满足需求。
应注意，网络设备调度终端的上行传输，以使得各个成员载波的上行功率满足需求时，应使得第一成员载波的上行发送功率不超过终端的最大可用发送功率与第二成员载波的发送功率的差值。
本申请实施例中，网络设备不仅根据第一成员载波的功率余量对终端的上行传输进行调度，而且还根据终端是否使用了最大可用发送功率，以及第二成员载波的上行功率的可调范围，对终端的上行传输进行调度。也就是说，网络设备可以根据更多的参数调度终端的上行传输，从而有助于更好地控制终端各个成员载波的上行功率。
此外，由于子载波间隔较大的第一成员载波的时隙较小，因此，终端使用子载波间隔较大的第一成员载波来发送第一信息、第二信息和第三信息，可以使得网络设备可以更为及时地获知第一信息、第二信息和第三信息，从而可以更及时地根据第一信息、第二信息和第三信息对终端进行调度。
进一步地，网络设备与终端在NR系统的载波聚合模式下通信时，第一成员载波的子载波间隔可以是网络设备给终端配置的多个成员载波中子载波间隔最大的成员载波，这有助于进一步提高调度的及时性。
网络设备与终端之间在LTE系统与NR系统间双连接的模式下通信时，或网络设备与终端之间在NR系统内双连接的模式下通信时，第一成员载波的子载波间隔可以是第一成员载波所属的载波组中子载波间隔最大的成员载波，这有助于进一步提高调度的及时性。
S210中，终端使用第一成员载波发送第一信息、第二信息、第三信息，可以包括：终端在确定触发条件得到满足时，使用第一成员载波发送第一信息、第二信息和第三信息。其中，触发条件包括：第一成员载波的时隙与第二成员载波对应的时隙具有重叠部分。
也就是说，终端确定使用第一成员载波进行上行传输的时隙与终端使用第二成员载波进行上行传输的时隙重叠了，然后使用子载波间隔较大的第一成员载波发送第一信息、第二信息和第三信息。网络设备可以根据第一信息、第二信息和第三信息对第一成员载波与第二成员载波重叠的下一个上行时隙进行调度。
如图3所示，第一成员载波的子载波间隔为120kHz，第二成员载波的子载波间隔为15kHz，第二成员载波的时隙长度为第一成员载波的时隙长度的8倍。第二成员载波的一个上行时隙与第一成员载波的三个上行时隙重叠。
终端确定第二成员载波的时隙与第一成员载波的第一个时隙重叠时，使用第一成员载波在第一个重叠时隙(即第一成员载波的第一个时隙)发送第一信息、第二信息和第三信息。网络设备接收第一信息、第二信息和第三信息后，根据第一信息、第二信息和第三信息对第一成员载波的第二个重叠时隙(即第一成员载波的第四个时隙)进行上行调度，使 得调度后的第一成员载波的在第二个重叠时隙中的上行发送功率不超过第三信息指示的差值。
同理，终端确定第二成员载波的时隙与第一成员载波的第四个时隙重叠时，使用第一成员载波在第二个重叠时隙发送第一信息、第二信息和第三信息。网络设备接收第一信息、第二信息和第三信息后，根据第一信息、第二信息和第三信息对第一成员载波的第三个重叠时隙(即第一成员载波的第六个时隙)进行上行调度，使得调度后的第一成员载波的在第三个重叠时隙中的上行发送功率不超过第三信息指示的差值。
终端在触发条件得到满足的情况下才发送第一信息、第二信息和第三信息，可以使得网络设备可以在终端满足触发条件时才根据第一信息、第二信息和第三信息调度终端的上行传输，从而可以提高网络设备的调度效率。
S210中，终端具体可以通过媒体访问控制(media access control，MAC)控制单元(control elment，CE)或无线资源控制(radio resource control，RRC)信令发送第一信息、第二信息和第三信息。
S220中，网络设备根据第一信息。第二信息和第三信息对终端的上行传输进行调度，可以包括以下任意一种或多种调度行为。
第一种调度行为：网络设备根据第一信息确定第一成员载波的功率余量大于0，且根据第二信息确定终端的发送功率等于终端的最大可用发送功率时，根据第三信息减少第一时隙中在第一成员载波上位终端分配的频域资源，第一时隙位于第二时隙之后，第二时隙为终端通过第一成员载波发送第一信息所使用的时隙。
换句话说，第一成员载波在当前重叠时隙(即第二时隙)的功率余量大于0，终端当前的发送功率等于终端的最大可用发送功率时，网络设备保证第一成员载波在后续重叠时隙(即第一时隙)中的上行功率不超过第三信息指示的差值的同时，减小在该后续重叠时隙中第一成员载波上为该终端分配的频域资源。
第二种调度行为：网络设备根据第一信息确定第一成员载波的功率余量大于0，且根据第二信息确定终端的发送功率不等于终端的最大可用发送功率时，根据第三信息增加第一时隙中在第一成员载波上为该终端分配的频域资源，其中，第一时隙位于第二时隙之后，第二时隙为终端通过第一成员载波发送第一信息所使用的时隙。
换句话说，第一成员载波在当前重叠时隙(即第二时隙)的功率余量大于0，终端当前的发送功率不等于终端的最大可用发送功率时，网络设备保证第一成员载波在后续重叠时隙(即第一时隙)中的上行功率不超过第三信息指示的差值的同时，增加该后续重叠时隙中第一成员载波上为终端分配的频域资源。
第三种调度行为：网络设备根据第一信息确定第一成员载波的功率余量小于0，且根据第二信息确定终端的发送功率不等于终端的最大可用发送功率时，根据第三信息减小第一时隙中在第一成员载波上位为该终端分配的频域资源，其中，第一时隙位于第二时隙之后，第二时隙为终端通过第一成员载波发送第一信息所使用的时隙。
换句话说，第一成员载波在当前重叠时隙(即第二时隙)的功率余量小于0，终端当前的发送功率不等于终端的最大可用发送功率时，网络设备保证第一成员载波在后续重叠时隙(即第一时隙)中的上行功率不超过第三信息指示的差值的同时，减小该后续重叠时隙中第一成员载波上位为终端分配的频域资源。
第四种调度行为：网络设备根据第一信息确定第一成员载波的功率余量小于0，且根据第二信息确定终端的发送功率等于终端的最大可用发送功率时，根据第三信息减小第一时隙中在第一成员载波上为终端分配的频域资源，其中，第一时隙位于第二时隙之后，第二时隙为终端通过第一成员载波发送第一信息所使用的时隙。
换句话说，第一成员载波在当前重叠时隙(即第二时隙)的功率余量小于0，终端当前的发送功率等于终端的最大可用发送功率时，网络设备保证第一成员载波在后续重叠时隙(即第一时隙)中的上行功率不超过第三信息指示的差值的同时，减小该后续重叠时隙中第一成员载波上为终端分配的频域资源。
应理解，上述网络设备的调度行为只是示例，本申请实施例对网络设备根据第一信息、第二信息和第三信息的上行调度行为并不作限制。
本申请另一个实施例的通信方法的示意性流程图如图4所示。应理解，图4示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图4中的各个操作的变形。此外，图4中的各个步骤可以按照与图4呈现的不同的顺序来执行。
S410，网络设备根据网络设备给终端配置的多个成员载波的子载波间隔，将多个成员载波中的至少一个成员载波划分为第一载波组。
本申请实施例中，网络设备可以为终端配置多个成员载波。
如，网络设备与终端之间在LTE系统与NR系统间双连接的模式下通信时，网络设备可以为终端配置LTE系统中子载波间隔为15kHz的成员，同时，为终端配置NR系统中子载波间隔为15*2 n kHz的成员载波，n为整数。
网络设备为终端配置多个成员载波的一种示例如图5所示。即网络设备为终端配置LTE系统中子载波间隔为15kHz的成员载波，为终端配置NR系统中子载波间隔为15kHz、30kHz、60kHz和120kHz的成员载波。
网络设备为终端配置多个成员载波后，可以根据这多个成员载波的子载波间隔，将这多个成员载波划分为多个载波组。
其中，网络设备可以将子载波间隔相同的成员载波划为同一个载波组；或者，网络设备可以将子载波间隔为15kHz的成员载波化为同一个载波组，同时，将其他所有成员载波化为同一个载波组。
本申请实施例中，可以将划分所得的多个载波组中子载波间隔为15kHz的载波组称为第一载波组。如网络设备给终端配置如图5所示的成员载波时，网络设备将15kHz的两个成员载波划分为一个载波组。该载波组可以称为第一载波组。
S420，网络设备向终端发送第二信息，第二信息用于配置第一载波组。相应地，终端接收第二信息，并根据第二信息配置第一载波组。
换句话说，网络设备向终端发送载波组的划分结果，终端根据该划分结果配置载波组。
可选地，第二信息可以包括第一载波组中所有成员载波的信息(如所有成员载波的标识)、这些成员载波为一个载波组的信息。
如网络设备将图5所示的成员载波1和成员载波2划分为第一载波组时，第二信息可以包括：成员载波1的标识和成员载波2的标识，成员载波1和成员载波2为第一载波组的信息。
可选地，在网络设备发送第二信息之前，网络设备可以向发送为终端配置的所有成员载波的信息。此时，第二信息具体可以包括：第一载波组中所有成员载波在网络设备为终端配置的所有成员载波中的索引、这些成员载波为一个载波组的信息。
如网络设备可以向终端发送如图5所示的成员载波1至成员载波5的标识。网络设备将成员载波1和成员载波2划分为第一载波组时，第二信息可以包括：成员载波1的索引(即索引1)和成员载波2的索引(即索引2)，成员载波1和成员载波2为第一载波组的信息。
S430，网络设备对第一载波组进行上行调度。换句话说，网络设备对所有载波组进行上行调度。
网络设备对第一载波组进行上行调度的行为示例如下。
如将图5所示的成员载波1与成员载波2划分为第一载波组，将其他成员载波全部划分为第二载波组或者其他成员载波分别自成一组，且LTE系统与NR系统为同步双连接时，网络设备可以调度终端使用如LTE中的功率控制模式1(power control mode 1，PCM1)对所有的载波组进行功率控制。即调度终端根据所有载波组中的成员载波承载的信道或信号或业务的传输优先级进行跨载波组(across CGs)功率缩放的方法对所有载波组进行功率控制。
如将图5所示的成员载波1与成员载波2划分为第一载波组，将其他成员载波全部划分为第二载波组或者其他成员载波分别自成一组，且LTE系统与NR系统为异步双连接时，网络设备可以调度终端使用如LTE中的功率控制模式2(power control mode 2，PCM2)。即给各个载波组半静态配置一个保证功率(guaranteed power)，并调度终端根据传输时间的先后优先级为各个载波组分配剩余功率(reminding power)。
如将图5所示的成员载波1与成员载波2划分为第一载波组，将其他成员载波全部划分为第二载波组或者其他成员载波分别自成一组，且LTE系统与NR系统为异步双连接时，可以调度终端采用look-ahead模式对成员载波1和成员载波2进行功率控制。
其中，网络设备可以向终端发送第一信息，第一信息指示终端采用look-ahead模式对第一载波组进行功率控制。
具体地，网络设备根据多个成员载波的子载波间隔，将多个成员载波中子载波间隔为第二子载波间隔的成员载波划分为第二载波组，第二子载波间隔大于第一子载波间隔；网络设备向终端发送第一信息，第一信息指示终端采用look-ahead模式对第一载波组进行功率控制。
look-ahead模式即：终端根据第一时隙中第二载波组的上行功率，以及第一载波组中的成员载波的信道优先级或信号优先级或业务优先级，调整第一载波组的上行功率，第一时隙与第二时隙重叠，且第一时隙的上行定时位于第二时隙的上行定时之后，第二时隙为终端使用第一载波组进行上行传输的时隙。
其中，信号优先级可以是上行控制信息(uplink control information，UCI)的优先级。
当然，终端还可以根据第二载波组中的成员载波的信道优先级或信号优先级或业务优先级，调整第一载波组的上行功率。
应了解，look-ahead模式下，终端可以对第一载波组和第二载波组进行组间功率控制，也可以对第一载波组进行组内功率控制。
具体地，如图6所示，成员载波1与成员载波2异步，即成员载波1的时隙的上行定时与成员载波2的时隙的上行定时没有对齐，且成员载波2的第j个时隙与第j+1个时隙均与成员载波1的第i个时隙重叠。其中，成员载波1与成员载波2可以是同一个载波组中的成员载波，也可以是不同载波组中的成员载波；成员载波1的子载波间隔与成员载波2的子载波间隔可以相同，也可以不相同。
此时，终端可以根据成员载波2在第j个时隙中的上行功率对成员载波1在第i个时隙的上行功率进行控制。此外，终端还可以根据成员载波2在第j+1个时隙中承载的信道、信号或业务的优先级以及成员载波1在第i个时隙中承载的信道、信号或业务的优先级对成员载波1在第i个时隙的上行功率进行控制。更具体地，可以使用LTE中的PCM1模式对成员载波1在第i个时隙的上行功率进行控制。
网络设备将所有成员载波中子载波间隔为15kHz以外的成员载波全部划分为一个载波组时，网络设备可以使用如图2所示的通信方法对该载波组中的成员载波进行功率控制。为了简洁，此处不再赘述。
图7是本申请另一个实施例的通信方法的示意性流程图。应理解，图7示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图7中的各个操作的变形。此外，图7中的各个步骤可以按照与图7呈现的不同的顺序来执行。
S710，终端确定第一时隙与第二时隙的重叠部分，第一时隙为终端使用第一成员载波的时隙，第二时隙为终端使用第二成员载波的时隙，第一成员载波上承载第一信道或第一信号或第一业务，第二成员载波上承载第二信道或第二信号或第二业务，第二信道或第二信号或第二业务的优先级高于第一信道或第一信号或第一业务的优先级。
S720，终端调整第一时隙与第二时隙的重叠部分中第一成员载波的上行功率。
如图8所示，网络设备给终端配置成员载波1和成员载波2，成员载波1的子载波间隔为15kHz，成员载波2的子载波间隔为120kHz。成员载波2上承载的信道或信号或业务不能降低上行发送功率，如成员载波2上承载的是物理上行控制信道(physic uplink control channel。PUCCH)或物理随机接入信道(physical random access channel，PRACH)或低时延高可靠连接(Ultra-reliable and low latency communications，URLLC)业务等。并且，成员载波1的时隙与成员载波2的时隙重叠部分的功率之和超过或等于终端的最大可用发送功率。若成员载波1上承载的信道或信号或业务可以降低上行发送功率，如增强移动宽带(enhanced mobile broad band，eMBB)业务，则终端可以调整成员载波1在第一时隙与第二时隙的重叠部分中的上行功率。
应理解，网络设备与终端在NR系统的载波聚合模式下通信时，终端的最大可用发送功率可以由终端的能力决定。
网络设备与终端之间在LTE系统与NR系统间双连接的模式下通信时，或网络设备与终端之间在NR系统内双连接的模式下通信时，即网络设备为终端配置的多个成员载波可以分为多个载波组时，终端的最大可用发送功率可以为其中需要进行功率控制的载波组的最大可用发送功率。
可选地，终端调整第一时隙与第二时隙的重叠部分中第一成员载波的上行功率，可以包括：终端在第一时隙内除该重叠部分外的时隙中，使用第一成员载波发送上行数据。
换句话说，终端将位于第一时隙的重叠部分中的成员载波1上的码块组(code block group，CBG)打掉不传，以帮助优先级高的成员载波2上的信道、信号或业务的传输能够分配到足够的传输功率。
上述打掉不传的CBG可以在其他上行时隙进行重传。
可选地，终端调整第一时隙与第二时隙的重叠部分中第一成员载波的上行功率，可以包括：终端降低该重叠部分中第一成员载波上承载业务数据的资源的发送功率；或只在第一成员载波承载的参考信号和/或控制信息所在的资源上发送信号。
换句话说，终端可以降低位于第一时隙的重叠部分中的成员载波1上的数据资源的上行功率。如果需要，可以不传位于第一时隙的重叠部分中的成员载波1上的业务数据，而保留其他信道或信号的上行传输，如仅传输解调参考信号(demodulation reference signal，DMRS)和/或上行控制信息。
本申请实施例进一步给出实现上述方法实施例中各步骤及方法的装置实施例。前述方法实施例的方法、步骤、技术细节以及技术效果等同样适用于装置实施例，后续不再详细说明。
