Description

一种通信方法及装置 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
终端发送信号时，在基带生成基带信号后，会经过射频发射链路(下文中将简称为发射链路)生成射频信号，然后经过天线发送出去，如图1所示。终端在接收信号的时候，也会有对应的射频接收链路(下文中将简称为接收链路)(图1中未示出)。在长期演进(long term evolution，LTE)和新空口(new radio，NR)中，终端可以支持多个发射链路。比如，终端支持一个发射链路和两个接收链路，可以表示为：终端支持1T(Transmit)2R(Receive)。
在NR中引入了双连接(dual connectivity，DC)。即一个终端同时连接两个基站的场景，该两个基站中一个作为主基站，另一个为辅基站。在DC场景下，终端会具有至少两个发射链路，终端与主基站和辅基站分别使用不同的发射链路通信(例如，Tx1和Tx2，其中Tx1用于与主基站通信，Tx2用于与辅基站通信)。由于终端并非每时每刻均与主基站或者辅基站进行上行传输。因此，在终端未与主基站(或者辅基站)进行上行传输时，终端与主基站之间的Tx1通常处于闲置状态。在终端未与主基站(或者辅基站)进行上行传输时，如果利用Tx1和Tx2与辅基站(或者主基站)通信可以提高与辅基站(或者主基站)之间的发送数据率。因此，如何配置终端使用闲置的发射链路与基站进行通信是亟需解决的技术问题。
发明内容
本发明实施例提供一种通信方法及装置，用以提升上行传输过程中的发送数据率。
为了解决上述技术问题，本申请实施例提供如下技术方案：
第一方面，本申请实施例提供一种通信方法，该方法包括：终端获取用于指示终端与第一小区在至少两个时间资源内通信时具有不同的通信能力的第一消息；终端根据在至少两个时间资源内终端与第一小区通信时分别具有的通信能力与第一小区进行通信。
本申请实施例提供一种通信方法，通过终端根据第一消息确定在不同时间资源内终端与第一小区具有的通信能力，并根据在至少两个时间资源内中的每个时间资源上对应的通信能力与第一小区通信。由于不同时间资源上终端与第一小区通信时具有不同的通信能力，不同的通信能力通常所达到的上行传输效率不同，因此，与终端仅使用终端本身具有的通信能力和第一小区进行上行传输相比，可以提升上行发送数据率，且提升通信性能。
一种可能的实现方式，至少两个时间资源包括第一时间资源和第二时间资源，第一消息为终端与第二小区通信时采用的上下行子帧配置，本申请实施例提供的方法还包括：终端在第一时间资源内使用第一通信能力与第一小区进行通信，所述终端在第二时间资源内使用第二通信能力与第一小区进行通信，其中，所述第一时间资源与所述上下行子帧配置中的下行子帧中的部分或者全部时间资源相对应；所述第二时间资源与所述上下行子帧配置中的上行子帧中的部分或者全部时间资源相对应，其中，所述第一通信能力大于所述第二通信能力。终端通过上下行子帧配置获取不同时间资源内终端与第一小区通信时通信能力的切换，这样在终端与第二小区为下行传输时，可以使用终端与第二小区通信时的传输链路从而实现传输链路共享，从而提高传输链路使用率，提升上行传输速率。

一种可能的实现方式，第一消息包括：第一指示信息以及第一周期，所述第一指示信息包括N个由第一信息和第二信息构成的比特序列，其中，所述第一信息用于指示所述通信能力为第一通信能力，所述第二信息用于指示所述通信能力为第二通信能力，其中，N为大于或等于1的整数；所述终端根据所述第一指示信息确定在所述第一信息对应的时间资源内，所述通信能力为所述第一通信能力；终端根据第一指示信息确定在所述第二信息对应的时间资源内，所述通信能力为所述第二通信能力。通过第一指示信息终端可以获取在至少两个时间资源内第一通信能力和第二通信能力进行切换的时间资源，可以实现射频链路共享，提高射频链路使用率，提升上行传输速率。

本申请实施例描述的系统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。
本申请中的通信方法可适用于多种系统架构，如图2所示，图2示出了本发明实施例提供的一种通信系统示意图，该通信系统包括：一个或者多个终端(图2中以一个终端为例，即终端101)，以及与一个或者多个终端通信的第一网络设备102和第二网络设备103。其中，第一网络设备102和第二网络设备103之间通过第一接口通信。第一网络设备102和第二网络设备103分别通过第二接口与一个或者多个终端通信。其中，网络设备覆盖的小区可以为一个或多个小区，本申请对此不做具体限定。
示例性的，如图2所示，第一网络设备102覆盖的小区为第一小区1，第二网络设备103覆盖的小区为第二小区2。可以理解的是，本申请实施例以一个网络设备覆盖一个小区为例进行说明。
第一网络设备102和第二网络设备103用于为一个或者多个终端101提供无线资源。第一网络设备102和第二网络设备103中一个网络设备用作主网络设备，另一个网络设备用作辅网络设备。例如，第一网络设备102为主网络设备，第二网络设备103为辅网络设备。
其中，主网络设备是指终端101在随机接入过程中接入的第一个网络设备。主网络设备负责与核心网控制面实体之间建立控制面连接，传输信令消息，以及决定是否为终端101创建辅基站，并为终端101选择辅网络设备。
辅网络设备，主网络设备之外的第二网络设备，用于为终端101提供额外的无线资源的节点，与核心网控制面实体之间可以没有直接的控制面连接。
一种示例，本申请实施例中第一网络设备102和第二网络设备103可以相同网络制式的网络设备。例如，以网络设备为基站为例，第一网络设备102和第二网络设备103分别对应的网络制式为4G场景下的演进型基站(evolved Node B，eNB或eNodeB)。此时，第一接口为X2接口。
又例如，第一网络设备102和第二网络设备103分别对应的网络制式可以均为NR场景下的基站(例如，gNB)。
另一种示例，本申请实施例中的第一网络设备102和第二网络设备103可以为不同网络制式的网络设备。例如，第一网络设备102对应的网络制式为4G场景下的eNB，第二网络设备103对应的网络制式为NR场景下的gNB。
又例如，第一网络设备102对应的网络制式为NR场景下的gNB，第二网络设备103对应的网络制式为4G场景下的eNB。
又一种示例，第一网络设备102为第三代合作伙伴计划(3rd generation partnership  project，3GPP)协议基站，第二网络设备103为非3GPP协议基站。
由于第一网络设备102和第二网络设备103对应的网络制式不同，第一接口的名称也存在差异，因此下述将分别介绍：
当第一网络设备102和第二网络设备103对应的网络制式均为NR下的gNB时，第一接口为Xn接口，支持第一网络设备102和第二网络设备103之间的信令交互。
当第一网络设备102对应的网络制式为4G场景下的eNB，第二网络设备103对应的网络制式为NR场景下的gNB时，第一接口为X2接口。当第一网络设备102和第二网络设备103分别对应的网络制式为eNB时，第一接口为X2接口。当第一网络设备102对应的网络制式为NR下的gNB，第二网络设备103对应的网络制式为LTE下的eNB时，第一接口为X2接口。
可以理解的是，上述第一接口的名称仅是个示例，本申请实施例对第一基站和第二基站之间的接口名称不作限定。
不论第一网络设备102和第二网络设备103采用哪种网络制式，主网络设备和终端之间建立有无线Uu口，当第一网络设备102作为主网络设备时，第一网络设备102可与终端之间传输用户面数据与控制面信令。第二网络设备103作为辅网络设备，第二网络设备103和终端之间也建立有无线Uu口，可与终端间传输用户面数据。也就是说，终端处于双连接架构模式(Dual Connectivity，DC)。其中，Uu接口的用户平面主要传输用户数据；控制平面传输相关信令，建立、重新配置和释放各种移动通信无线承载业务。
其中，一个或者多个终端中任一个终端具有至少两个发射链路(即下述实施例中的传输链路，也即本申请下文中描述的传输链路即指终端和第一小区/第二小区进行上行通信时所使用的发射链路)和至少两个接收链路。其中，终端使用至少两个发射链路中的至少一个发射链路向第一小区/第二小区发送上行数据或者上行信令。终端可以通过至少两个接收链路中的至少一个接收链路接收第一小区/第二小区分别所属的网络设备发送的下行数据或者下行信令。
示例性的，如图2所示，终端101使用第一传输链路104与第一网络设备102覆盖的第一小区1通信，终端101使用第二传输链路105与第二网络设备103覆盖的第二小区2通信。
如图3所示，图3示出了本申请实施例提供的另一种通信系统，该通信系统包括：一个或者多个终端(图3中以一个终端为例，即终端101)，以及与一个或者多个终端通信的网络设备106。其中，网络设备106覆盖的小区为两个或两个以上，本申请实施例对此不作限定。
示例性的，在图3中以网络设备106覆盖的小区为第一小区1和第二小区2为例。终端可以与第一小区1和第二小区2通信。
示例性的，终端使用第一传输链路104与第一小区1通信，终端使用第二传输链路105与第二小区2通信。
可以理解的是，当图2所示的通信系统中网络设备覆盖两个或两个以上的小区时，终端与任一个网络设备包括的多个小区进行通信的方式可以参考图3所示的架构，本申请实施例对此不作限定。
本申请中的第一网络设备102、网络设备106或第二网络设备103可以为能够与终端进行通信的基站。例如，可以是无线局域网(Wireless Local Area Network，WLAN)中的接 入点(access point，AP)，全球移动通信系统(Global System for Mobile Communications，GSM)或码分多址接入(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolved Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及未来5G网络中的基站(gNB)或者未来演进的公用陆地移动网(Public Land Mobile Network，PLMN)网络中的网络设备等。
可以理解的是，网络设备为基站时，主网络设备便可以称为主基站，辅网络设备便可以称为辅基站。
终端(terminal)是一种向用户提供语音和/或数据连通性的设备。例如，具有无线连接功能的手持式设备、车载设备等。终端也可以称为用户设备(User Equipment，UE)、接入终端(Access Terminal)、用户单元(User Nnit)、用户站(User Station)、移动站(Mobile Station)、移动台(mobile)、远方站(Remote Station)、远程终端(remote terminal)、移动设备(Mobile equipment)、用户终端(User Terminal)、无线通信设备(wireless telecom equipment)、用户代理(User Agent)、用户装备(User Equipment)或用户装置。终端可以是无线局域网(Wireless Local Area Networks，WLAN)中的站点(station，STA)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统(例如，第五代(fifth-generation，5G)通信网络)中的终端或者未来演进的公共陆地移动网络(Public Land MobileNetwork，PLMN)网络中的终端等。其中，5G还可以被称为新空口(New Radio，NR)。
作为示例，在本发明实施例中，该终端还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
由于未来接入网可以采用云无线接入网(Cloud Radio Access Network，C-RAN)架构来实现，一种可能的方式是将传统基站的协议栈架构和功能分割为两部分，一部分称为集中单元(Central Unit，CU)，另一部分称为分布单元(Distributed Unit，DU)，而CU和DU的实际部署方式比较灵活，例如多个基站的CU部分集成在一起，组成一个规模较大的功能实体。如图4所示，其为本申请实施例提供的一种网络架构的示意图。如图4所示，该网络架构包括核心网(Core Network，CN)设备和接入网(以无线接入网(Radio Access Network，RAN)为例)设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成基带装置中，或者部分拉远部分集成在基带装置中。例如，在LTE通信系统中，RAN设备(eNB)包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置 (例如射频拉远单元(Radio Remote Unit，RRU)相对于基带处理单元(Building Base Band Unit，BBU))，RAN设备由一个节点实现，该节点用于实现无线资源控制(Radio Resource Control，RRC)、分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)、无线链路控制(radio link control，RLC)、媒体接入控制(Medium Access Control，MAC)等协议层的功能。再如，在一种演进结构中，基带装置可以包括集中单元(Centralized Unit，CU)和分布单元(Distributed Unit，DU)，多个DU可以由一个CU集中控制。如图4所示，CU和DU可以根据无线网络的协议层划分，例如分组数据汇聚层协议层及以上协议层的功能设置在CU，PDCP以下的协议层，例如无线链路控制(Radio Link Control，RLC)和媒体接入控制层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
此外，请继续参考图5，相对于图4所示的架构，还可以将CU的控制面(Control Plane，CP)和用户面(User Plane，UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
下行数据的传输流程为：CU收到核心网发送的下行数据后，将下行数据分发给DU，DU将接收到的下行数据发送给终端。上行数据的传输流程为：终端将上行数据发送给DU，DU将接收到的上行数据发送给CU，CU在收到DU发送的上行数据后，将接收到的上行数据发送给核心网。
在以上网络架构中，CU产生的数据可以通过DU发送给终端，或者终端产生的数据可以通过DU发送给CU。DU可以不对该数据进行解析而直接通过协议层封装后传给终端或CU。例如，RRC或PDCP层的数据最终会处理为物理层(Physical Layer，PHY)的数据发送给终端，或者，由接收到的PHY层的数据转变而来。在这种架构下，该RRC或PDCP层的数据，即也可以认为是由DU发送的。
在以上实施例中CU划分为RAN中网络设备，此外，也可以将CU划分为CN中的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端或网络设备。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点功能的RAN设备。
本申请实施例中一种通信方法的执行主体可以为终端，也可以为应用于终端中的装置，例如，芯片。一种确定通信能力的方法的执行主体可以为网络设备，也可以为应用于网络设中的装置，例如，芯片。下述实施例仅以通信方法的执行主体为终端，确定通信能力的方法的执行主体为网络设为例。
如图6所示，图6示出了本申请实施例提供的一种通信方法和确定通信能力的方法的流程示意图，该方法包括：
S101、网络设备向终端发送第一消息，该第一消息用于指示终端与第一小区在至少两个时间资源内通信时具有不同的通信能力。
其中，第一小区为与终端通信的多个小区中的任一个小区。
一方面，第一小区和第二小区为不同网络设备覆盖下的小区的情况下：此处的网络设备可以为第一小区所属的网络设备，例如，在图2所示的系统架构中，网络设备可以为第一网络设备102。此处的网络设备也可以为第二小区所属的网络设备，例如，如图2所示的第二网络设备103，本申请实施例对此不作限定。
另一方面，当第一小区和第二小区为同一个网络设备覆盖下的小区的情况下：此处的网络设备可以为第一小区和第二小区共同所属的网络设备。例如，此处的网络设备为图3所示的网络设备106。
该第一消息可以由网络设备以半静态配置方式配置给终端。例如，网络设备通过无线资源控制(Radio Resource Control，RRC)消息配置给终端。
其中，通信能力包括以下参数中的一项或者多项：最大传输链路数量、最大传输层数、最大传输秩Rank数和最大端口数目。
需要说明的是，本申请实施例中终端具有至少两个通信能力，例如，第一通信能力和第二通信能力。其中，在不同时间资源上终端可以使用不同的通信能力与第一小区进行上行传输。
其中，第一通信能力大于第二通信能力。
本申请实施例中第一通信能力大于第二通信能力指：终端使用第一通信能力向第一小区进行上行传输时所能达到的效果大于终端使用第二通信能力向第一小区进行上行传输时所能达到的效果。例如，使用第一通信能力时数据速率大于使用第二通信能力进行通信时的通信速率。
结合现有技术中的描述，终端与一个小区通信时，通常可以使用一个传输链路(可以把这个传输链路看作终端与小区之间通信时使用的一种通信能力)，但是并非每时每刻该传输链路上均具有上行传输。因此，在该传输链路上不具有上行传输时，网络设备可以指示终端使用该传输链路与其他小区通信。基于此，可以理解的是，第一通信能力：不仅仅包括终端与第一小区本身具有的通信能力还包括：终端与其他小区之间具有的处于空闲状态的通信能力。
其中，第一通信能力具体指最大传输链路数量/最大传输层数量/最大传输秩Rank数量/最大天线端口数量为多个或2T。
其中，处于空闲状态的通信能力是指：在某一个时间资源内终端与网络设备覆盖的小区并未使用该通信能力进行上行传输，或者在某一个时间资源上该通信能力上未具有上行传输。
处于非空闲状态的通信能力是指：在某一个时间资源内终端与网络设备覆盖的小区使用该通信能力进行上行传输或者该通信能力上具有上行传输。下述但凡涉及到传输链路/天线端口/传输Rank/传输层处于空闲状态或者非空闲状态，均可以参考此处的描述，后续不再赘述。
具体的，以通信能力为最大传输链路数量为例，当终端在某一个时间资源1上未使用终端与其他小区之间的传输链路1进行上行传输或者在该传输链路1上未进行上行传输，则终端可以在时间资源1上使用传输链路1以及终端与第一小区具有的传输链路2，与第一 小区进行通信。
在实际过程中网络设备可以指示终端与每个小区进行通信时所使用的最大传输层数，例如，终端本身具有4个传输层，网络设备可以指示终端可以使用该传输层中的两个传输层与第一小区通信，也可以使用另外两个传输层与第二小区通信。当终端在某一个时间资源1上未使用终端与其他小区之间的两个传输层进行上行传输或者在该两个传输层上未进行上行传输时，则终端可以使用4个传输层与第一小区进行通信。
第二通信能力为终端与第一小区通信时，本身具有的通信能力，且不包括终端与其他小区之间具有的通信能力。
第二通信能力具体指：最大传输链路数量/最大传输层数量/最大传输秩Rank数量/最大天线端口数量为单个或1T。
例如，以通信能力为最大传输链路数量为例，如果终端与第一小区之间本身具有一个传输链路1，则终端在某个时间资源上与第一小区进行通信的通信能力为第二通信能力时，则终端在该时间资源上使用传输链路1与第一小区通信。
在同等条件下，本申请实施例中终端使用“2T”的通信能力进行上行传输时所能达到的通信效果大于终端使用“1T”的通信能力进行上行传输时所能达到的通信效果。
下述但凡涉及到通信能力包括的：最大传输层数量、最大传输Rank或者最大天线端口数目为2T或者1T的描述，均可以参考此处的描述，后续不再赘述。
本申请实施例中终端与小区进行通信可以理解为终端与该小区所属的网络设备进行通信，下述实施例但凡涉及到此描述，均可以参考此处的描述，后续不再赘述。
示例性的，以通信能力为最大传输链路数量为例，终端与第一小区之间的传输链路包括：传输链路11、传输链路12以及传输链路13，终端与第一小区使用第二通信能力通信包括：终端与第一小区使用传输链路11～传输链路13中的至少一个通信。
终端与第二小区之间的传输链路包括：传输链路21、传输链路22以及传输链路23。终端与第一小区使用第一通信能力通信包括：终端与第一小区使用传输链路21、传输链路22以及传输链路23中的至少一个以及传输链路11～传输链路13中的至少一个通信。
本申请实施例中的传输链路指终端与基站在进行上行传输时所使用的链路，可以指实际的射频链路，可以是有线(电)链路、无线(电)链路、宽带链路等等，本申请实施例对此不做限定。
下述实施例以至少两个时间资源包括第一时间资源和第二时间资源为例，该第一时间资源和第二时间资源为至少两个时间资源包括的多个时间资源中的任意两个，并不具有任何指示性含义：
其中，第一时间资源与下行子帧对应的全部时间资源或者部分时间资源相对应。第二时间资源与上行子帧对应的全部时间资源或者部分时间资源相对应。
示例1，第一消息包括终端与第二小区通信时采用的上下行子帧配置(uplink-downlink subframe configuration)。该上下行子帧配置中包括一个或者多个子帧，该一个或者多个子帧中每个子帧对应的上下行配置用于指示该子帧对应的时间资源内终端与第一小区通信(例如，进行上行传输)时的通信能力。其中，第一小区和第二小区为同一个网络设备覆盖下的小区或者为不同网络设备覆盖下的小区。
例如，以第二小区所属的网络设备对应的网络制式为LTE网络下的基站，当第二小区所属的网络设备使用时分双工(Time Division Duplexing，TDD)的工作模式时，则第二小 区所属的网络设备或者第一小区所属的网络设备可以通过RRC消息中TDD-Config>subframeAssignment字段向终端指示第二小区在TDD工作模式下的上下行子帧配置。如下所示：
TDD-Config………………………………《TDD配置信息》
The IE TDD-Config is used to specify the TDD specific physical channel configuration.《IE TDD配置信息用于指定TDD特定物理信道配置》
TDD-Config information element       《TDD配置信息内容》

ENUMERATED{ssp0，ssp1，ssp2，ssp3，ssp4，ssp5，ssp6，ssp7，ssp8}。
其中，subframeAssignment中的sa0，sa1，sa2，sa3，sa4，sa5，sa6用于指示TDD上下行的7种配置索引，如表1所示。其中，sa0用于指示TDD上下行配置索引0，sa1用于指示TDD上下行配置索引1等等specialSubframePatterns字段用于指示特殊子帧的配置，ssp0，ssp1，ssp2，ssp3，ssp4，ssp5，ssp6，ssp7，ssp8用于指示特殊子帧的9种不同配置索引，如表2所示。其中ssp0与特殊子帧配置索引0行配置相对应，ssp1与特殊子帧配置索引1行配置相对应等等。
具体的，该上下行子帧配置包括：上行子帧，用于指示上行传输、下行子帧，用于指示下行传输。
其中，网络设备和终端可以预定义该上下行子帧配置中的下行子帧，用于指示在下行子帧对应的全部时间资源或者部分时间资源(即第一时间资源)内，终端和第一小区通信时的通信能力为第一通信能力。该上下行子帧配置中的上行子帧，用于指示在上行子帧对应的全部时间资源或者部分时间资源(即第二时间资源)内，终端和第一小区通信时的通信能力为第二通信能力，其中，第一通信能力大于第二通信能力。
例如，以通信能力为最大传输链路数量为例，第一通信能力可以指终端与第一小区通信时的最大传输链路数量为第一最大传输链路数量，例如第一最大传输链路数量为多个(2T)。第二通信能力可以指终端与第一小区通信时的最大传输链路数量为第二最大传输链路数量，例如，第二最大传输链路数量为单个(1T)。通信能力为最大传输层数、最大传输秩Rank数、最大端口数目任一个时可以参考通信能力为最大传输链路数量的描述，后续不再赘述。
示例，如图2所示，以终端具有两个传输链路，即第一传输链路104和第二传输链路105，指示终端与第一小区之间的通信能力为第二通信能力时，终端和第一小区使用的最大传输链路数量为单个，例如，终端和第一小区使用终端和第一小区之间具有的第一传输链路104通信。当指示为终端与第一小区之间的通信能力为第一通信能力时，终端和第一小区使用的最大传输链路数量为多个，此时终端使用第一传输链路104和第二传输链路105与第一小区通信。
示例性的，在LTE中具体的TDD上下行子帧配置如下表1所示：
表1 上下行子帧配置

表1中的D表示下行子帧(downlink subframe)，S表示特殊子帧(special subframe)，U表示上行子帧(uplink subframe)。其中，特殊子帧用于下行传输和上行传输的转换。其中特殊子帧，包括：下行导频时隙(Downlink Pilot Time Slot，DwPTS)域、保护间隔(Guard Period，GP)域和上行导频时隙(Uplink Pilot Time Slot，UpPTS)域，这3个域的时长相加等于1毫秒(ms)。其中，DwPTS用于下行传输，UpPTS用于上行传输。
示例性的，终端中可以预配置有上述上下行子帧配置，也可以由第一小区所属的网络设备或者由第二小区所属的网络设备配置给终端。在这种情况下，第一小区所属的网络设备或者由第二小区所属的网络设备也可以向终端发送上下行子帧配置索引，以便于终端根据上下行子帧配置索引确定第一小区所属的网络设备或者由第二小区所属的网络设备所指示的上下行子帧配置。
特殊子帧有不同的配置，对应不同的DwPTS和UpPTS长度，如下表2所示：

特殊子帧配置是通过RRC消息中的TDD-Config->specialSubframePatterns字段来设置的。相应的，该specialSubframePatterns字段不仅用于指示特殊子帧的配置类型，也用于指示在该特殊子帧中终端在哪些或哪个符号上使用第一通信能力与第一小区通信，在哪些或哪个符号上使用第二通信能力与第一小区通信。如下所示：
TDD-Config      《TDD配置信息》
The IE TDD-Config is used to specify the TDD specific physical channel configuration。《IE TDD配置信息用于指定TDD特定物理信道配置》
TDD-Config information element     《TDD配置信息内容》
--ASN1START     《起始》
TDD-Config：：＝   SEQUENCE《序列》{
subframeAssignment《子帧配置》   ENUMERATED{sa0，sa1，sa2，sa3，sa4，sa5，sa6}，
specialSubframePatterns《特殊子帧的配置》ENUMERATED{ssp0，ssp1，ssp2，ssp3，ssp4，ssp5，ssp6，ssp7，ssp8}
其中，subframeAssignment中的sa0，sa1，sa2，sa3，sa4，sa5，sa6用于指示TDD上下行的7种配置索引，如表1所示。其中，sa0用于指示TDD上下行配置索引0，sa1用于指示TDD上下行配置索引1等等。
specialSubframePatterns字段用于指示特殊子帧的配置索引，ssp0，ssp1，ssp2，ssp3，ssp4，ssp5，ssp6，ssp7，ssp8用于指示特殊子帧的9种不同配置索引，如表2所示。其中ssp0与特殊子帧配置索引0行配置相对应，ssp1与特殊子帧配置索引1行配置相对应等等。
一种示例，当上下行子帧配置中还包括特殊子帧时，终端用于确定在特殊子帧对应的全部时间资源或者部分时间资源内通信能力为第一通信能力或第二通信能力。
示例性的，网络设备可以预定义当特殊子帧中包括DWPTS域时，在DWPTS域对应的全部时间资源或者部分时间资源内终端与第一小区通信时使用第一通信能力。
网络设备可以预定义当特殊子帧中为GP域或UpPTS域时，在GP域或UpPTS域分别对应的全部时间资源或者部分时间资源内终端与第一小区通信时使用第二通信能力。
或者，网络设备可以预定义当特殊子帧中为DWPTS域时，在DWPTS域对应的全部时间资源或者部分时间资源内终端与第一小区通信时使用第一通信能力。
当特殊子帧包括GP域时，与GP域对应的全部时间资源或者部分时间资源内，如果终端与第二小区之间具有的传输链路处于空闲状态，那么GP域对应的全部时间资源或者部分时间资源内终端与第一小区通信时的使用第一通信能力。在GP域对应的时间资源内，如果终端与第二小区之间具有的传输链路处于非空闲状态，那么在GP域对应的全部时间资源或者部分时间资源内终端与第一小区通信时的使用第二通信能力。
具体的，第一时间资源与GP域或DWPTS域对应的全部时间资源或者部分时间资源相对应。第二时间资源与GP域或UpPTS域分别对应的全部时间资源或者部分时间资源相对应。
其中，传输链路处于空闲状态可以指在某个时间资源内终端没有通过该传输链路与第二小区进行上行传输。或者可以指终端在某个时间资源内在该传输链路上没有和任何小区或者通信节点进行上行传输等等。
例如，该上下行子帧配置还可以复用SubframeAssignment-r15的上下行配置，具体的，复用SubframeAssignment-r15的上下行配置指示终端与第一小区通信时所使用的通信能力的方式可以参考上述实施例中复用TDD工作模式下的上下行子帧配置的方式，此处不再赘述。
示例性的，复用SubframeAssignment-r15的上下行配置如下所示：
ASN1START
SubframeAssignment-r15：：＝ENUMERATED{sa0，sa1，sa2，sa3，sa4，sa5，sa6}
其中，subframeAssignment-r15中的sa0，sa1，sa2，sa3，sa4，sa5，sa6用于指示TDD上下行的7种配置索引，如表1所示。其中，sa0用于指示TDD上下行配置索引0，sa1用于指示TDD上下行配置索引1等等。
本申请实施例中的终端使用通信能力与第一小区进行通信指终端使用该通信能力与第一小区进行上行传输。
需要说明的是，终端与第二小区进行通信时所使用的上下行子帧配置可以由第二小区所属的网络设备给终端，也可以由第一小区所属的网络设备发送给终端。当第一小区所属的网络设备和第二小区所属的网络设备为不同的网络设备时，第一小区所属的网络设备可以从第二小区所属的网络设备处获取终端与第二小区进行通信时所使用的上下行子帧配置，也可以从其他设备处获取终端与第二小区进行通信时所使用的上下行子帧配置，本申请实施例对此不作限定。
示例2，第一消息包括：用于指示通信能力为第一通信能力或第二通信能力的第一指示信息。
一种可能的实现方式，第一消息包括第一指示信息以及第一周期，所述第一指示信息包括第一信息和第二信息，其中，所述第一信息用于指示通信能力为第一通信能力，所述第二信息用于指示通信能力为第二通信能力。
示例性的，第一指示信息为传输转换pattern的位图信息，该传输转换pattern的位图信息可以由网络设备预配置给终端，然后终端将传输转换pattern的位图信息存储在终端的存储器中，也可以由厂商预存储在终端的存储器中，本申请实施例对此不作限定。
示例性的，第一指示信息可以采用bitmap的形式来表示，第一信息可以为“第一指示符”，第二信息可以为“第二指示符”。以第一指示符为“1”，第二指示符为“0”为例，第一指示信息可以表示为{1100011000，1010110101,1001110011,1000111111，……}中的任一个。其中“1”表示通信能力为第一通信能力，“0”表示通信能力为第二通信能力。
例如，通信能力为最大传输链路数量时，“1”表示最大传输链路数量为多个，“0”表示最大传输链路数量为单个。例如，通信能力为最大端口数目时，“1”表示最大端口数目为多个，“0”表示最大端口数目为单个。
例如，第一周期可以为{20ms，40ms，60ms，80ms，120ms，240ms，……}中的任一个。其中，第一周期用于指示所使用的第一指示信息的周期。
示例3，第一消息包括第二周期以及第三时间资源，其中，所述第二周期用于确定通信能力为第一通信能力的传输周期，所述第三时间资源用于指示在所述第二周期内所述通信能力为第一通信能力的时间长度。或者第一消息包括第二周期以及第四时间资源，其中， 所述第二周期用于确定通信能力为第二通信能力的传输周期，所述第四时间资源用于指示在所述第二周期内所述通信能力为第二通信能力的时间长度。
其中，第三时间资源或第四时间资源所指示的时间长度单位可以包含符号(symbols，可以简写为：sym)，时隙(slot)，子帧中的至少一个。
例如，第二周期可以为{20ms，40ms，60ms，80ms，120ms，240ms，……}中的任一个。
第一时间资源可以为{sym4，sym7，sym14，sym28，sym56，sym112，sym224……}中的任一个。其中，第一时间资源还可以用于指示符号的索引。第一时间资源包括一个或者多个时隙以及M个符号，其中M为大于或等于0的整数。
需要说明的是，当网络设备为终端配置第三时间资源时，终端便可以确定在某一个周期中除第三时间资源以外的时间资源终端与第一小区通信时使用第二通信能力。
在具体实现过程中，如果终端具有传输转换pattern的位图信息，且传输转换pattern的位图信息中每个传输转换pattern的位图信息对应一个索引，则网络设备可以向终端指示传输转换pattern的位图信息对应的索引，以便于终端根据索引确定传输转换pattern的位图信息。这样可以减少信令开销。
可以理解的是，上述第三时间资源、第二周期、第一周期的值仅是示例，在实际过程中还可以根据需要设置其他数值，在此不再赘述。
EN-DC场景下，当LTE载波与NR载波时间不同步(非ideal Backhaul场景)情况时，可以复用同步场景下的半静态配置的方案，在此不再赘述。
可以理解的是，最大传输链路数量为多个指：终端与小区之间通信所使用的最大传输链路包括：终端与一个或者多个小区之间具有的传输链路。通常情况下，终端与每个小区之间进行上行传输时会对应一个传输链路，即N个小区，终端通常会具有N个小区。因此，当指示终端与第一小区通信时的传输链路数量为多个时，终端可以使用N个传输链路中处于空闲状态的所有传输链路与第一小区通信。也即该N个传输链路中不仅包括终端与第一小区之间具有的传输链路，也包括终端与其他小区(例如，第二小区)之间具有的一个或者多个传输链路中的至少一个传输链路。
示例性的，以通信能力为最大传输链路数量为例，如图7所示，终端与第一网络设备102覆盖的第一小区通信时所使用的传输链路为传输链路1、传输链路2，终端与第二网络设备103覆盖的第二小区通信时所使用的传输链路为传输链路3。则在终端与第一小区通信时的通信能力为第一通信能力时，即终端与第一小区通信时时的最大传输链路数量为多个时，终端可以使用传输链路1、传输链路2和传输链路3与第一小区进行通信。或者终端使用传输链路1和传输链路3与第一小区进行通信。
本申请实施例中的最大输链路数量为单个可以指：终端与第一小区之间通信所使用的传输链路包括：终端具有的N个传输链路中为该第一小区分配的至少一个传输链路。且该至少一个传输链路属于终端和第一小区之间本身具有的传输链路，不包括终端与其他小区之间具有的传输链路。
示例性的，如图8所示，终端与第一小区具有的传输链路为传输链路1、传输链路2。终端与第二小区具有的传输链路为传输链路3，则终端与第一小区通信时的最大传输链路数量为单个时，终端可以使用传输链路1、传输链路2与第一小区进行通信。或者终端使用传输链路1与第一小区进行通信。
示例4，本申请实施例中的第一消息还可以包括至少两个时间资源以及至少两个时间资源中每个时间资源对应的通信能力。例如，时间资源1与第一通信能力关联，时间资源2与第二通信能力关联。这样终端在接收到第一消息后便可以确定至少两个时间资源对应的不同天线能力。
S102、终端获取第一消息。
其中，第一消息可以为网络设备发送的一条消息或者多条消息。
S103、终端根据第一消息，确定在不同时间资源内终端与第一小区通信时的通信能力。
示例性的，在第二小区与终端之间的通信能力处于空闲状态的时间资源内，终端与第一小区通信时的通信能力为第一通信能力。在第二小区与终端之间的通信能力处于非空闲状态的时间资源内，终端与第一小区通信时的通信能力为第二通信能力。
由于第一消息的内容不同，终端确定不同时间资源内终端与第一小区通信时的通信能力的方式存在差异，因此下述实施例将分别介绍：
一种示例，第一消息包括终端与第二小区通信时采用的上下行子帧配置。基于此，一种可能的实现方式中，S103可以通过以下方式实现：终端确定与所述上下行子帧配置中的下行子帧中的部分或者全部时间资源相对应的第一时间资源内使用第一通信能力，与所述上下行子帧配置中的上行子帧中的部分或者全部时间资源相对应所述第二时间资源使用第二通信能力。
例如：参见表1，当TDD configuration的索引为3时，如图9所示，图9以通信能力为最大传输链路数量为例，图9示出了终端与第一小区通信时最大传输链路数量切换的示意图。其中，在图9中与D子帧对应的时间资源内终端与第一小区使用第一通信能力通信，即终端与第一小区通信时的最大传输链路数量为多个(即图9中使用2T发送)，与U子帧对应的时间资源内终端与第一小区使用第二通信能力通信，即终端与第一小区通信时的最大传输链路数量为单个(即图10中使用1T发送)，S子帧内部也根据DwPTS、UpPTS区分为2T或者1T的发送时间资源。
另一种示例，上下行子帧配置还包括特殊子帧时，另一种可能的实现方式中，S103可以通过以下方式实现：在与所述特殊子帧包括的下行导频时隙DWPTS域或GP域对应的时间资源内，通信能力为第一通信能力。在与特殊子帧包括的保护间隔GP域对应的时间资源内或上行导频时隙UpPTS域对应的时间资源内，通信能力为第二通信能力。
又一种示例，第一消息包括：第一指示信息以及第一周期，所述第一指示信息包括N个由第一信息和第二信息构成的比特序列，其中，所述第一信息用于指示通信能力为第一通信能力，所述第二信息用于指示通信能力为第二通信能力，其中，N为大于或等于1的整数。基于此，S103可以通过以下方式实现：终端根据第一指示信息确定在所述第一信息对应的时间资源内，通信能力为第一通信能力。终端根据第一指示信息确定在所述第二信息对应的时间资源内，通信能力为第二通信能力。
示例性的，第一指示信息为1000111111，第一周期为20ms为例，如图10所示，图10示出了终端与第一小区通信时最大传输链路数量随时间资源动态切换的示意图。其中，在图10中与“1”对应的时间资源内，终端与第一小区通信时使用第一通信能力，即终端与第一小区通信时的最大传输链路数量为多个。与“0”对应的时间资源内，终端与第一小区通信时使用第二通信能力，即终端与第一小区通信时使用的最大传输链路数量为单个。
再一示例，第一消息包括第二周期以及第一时间资源，其中，第二周期用于确定通信 能力为第一通信能力的传输周期，第一时间资源用于指示在第二周期内通信能力为第一通信能力的时间长度时，步骤S103的再一种可能的实现方式为：
终端确定在第二周期内第一时间资源内，通信能力为第一通信能力。终端确定在第二周期内除第一时间资源以外的时间资源内，通信能力为第二通信能力。
示例性的，以第二周期为20ms，第二周期包括时隙1和时隙2，一个时隙包括14个符号(符号0～符号13)，第一时间资源为4个sym为例，如图11所示，图11示出了终端与第一小区通信时最大传输链路数量随时间资源动态切换的示意图。其中，在时隙1和时隙2内的符号0～符号3上终端与第一小区使用第一通信能力，即使用最大传输链路数量为多个(即2T)，在时隙1和时隙2内的符号4～符号13上终端与第一小区使用第二通信能力，即使用最大传输链路数量为单个(即1T)。
S104、终端基于在所述不同时间资源内确定的通信能力与第一小区通信。
具体的，步骤S104可以通过以下方式实现：通信能力为第一通信能力时，终端使用第一通信能力与第一小区通信。第二通信能力时，终端使用第二通信能力与第一小区通信。
例如，以通信能力为最大传输链路数量为例，终端使用第一通信能力与第一小区通信指：终端使用最大传输链路数量为多个与第一小区通信。终端使用第二通信能力与第一小区通信指：终端使用最大传输链路数量为单个与第一小区通信。
示例性的，如图12所示，其中，A表示第二小区和终端101之间的子帧为下行子帧对应的时间资源内，终端使用第一传输链路104和第二传输链路105与第一小区进行上行传输。B表示第二小区和终端101之间的子帧为上行子帧对应的时间资源内，终端使用第二传输链路105与第一小区进行上行传输。
可选的，本申请实施例提供的方法，还包括：S105、第一小区所属的网络设备接收终端在不同时间资源内确定的通信能力接收终端发送的上行传输。
本申请实施例提供一种通信方法，通过终端根据第一消息确定在不同时间资源内终端与第一小区具有的通信能力，并根据在至少两个时间资源内中的每个时间资源上对应的通信能力与第一小区通信。由于不同时间资源上终端与第一小区通信时具有不同的通信能力，不同的通信能力通常所达到的上行传输效率不同，因此，与终端仅使用终端本身具有的通信能力和第一小区进行上行传输相比，可以提升上行发送数据率，且提升通信性能。
上述主要从各个网元之间交互的角度对本申请实施例的方案进行了介绍。可以理解的是，各个网元，例如通信装置、确定通信能力的装置等为了实现上述功能，其包括了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
