Description

一种数据发送的方法和装置 技术领域
本申请施例涉及通信技术领域，尤其涉及一种数据发送的方法和装置。
背景技术
如图1所示，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。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)。
现有技术中，终端向小区发送上行数据时，通常从当前时刻之前已发送的一个或者多个已发送的探测参考信号(Sounding Reference Signal，SRS)中选择距离当前时刻最近的一个SRS。并根据所选择的SRS所使用的天线端口(port数目)发送上行数据。
但是，在实际过程中，终端发送上行数据所使用的天线端口数量可能会发生变化，这样便可能出现终端向某个小区发送上行数据所能采用的发送port数目与根据所选择的SRS所使用的天线端口数目不匹配的问题。

本申请实施例的技术方案可以应用于各种数据处理的通信系统，例如：码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)和其它系统等。术语“系统”可以和“网络”相互替换。CDMA系统可以实现例如通用无线陆地接入(universal terrestrial radio access，UTRA)、CDMA2000等无线技术。UTRA可以包括宽带CDMA(wideband CDMA，WCDMA)技术和其它CDMA变形的技术。CDMA2000可以覆盖过渡标准(interim standard，IS)2000(IS-2000)，IS-95和IS-856标准。TDMA系统可以实现例如全球移动通信系统(global system for mobile communication，GSM)等无线技术。OFDMA系统可以实现诸如演进通用无线陆地接入(evolved UTRA，E-UTRA)、超级移动宽带(ultra mobile broadband，UMB)、IEEE 802.11(Wi-Fi)，IEEE 802.16(WiMAX)，IEEE 802.20，Flash OFDMA等无线技术。UTRA和E-UTRA是UMTS以及UMTS演进版本。3GPP在长期演进(long term evolution，LTE)和基于LTE演进的各种版本是使用E-UTRA的UMTS的新版本。5G通信系统、新空口(new radio，NR)是正在研究当中的下一代通信系统。此外，通信系统还可以适用于面向未来的通信技术，都适用本申请实施例提供的技术方案。
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示出了本申请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/第二小区进行上行传输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所述，终端101具有多个传输链路，该多个传输链路用于终端101与第一网络设备102覆盖的第一小区1以及第二网络设备103覆盖的第二小区2通信。本申请实施例不限定多个 传输链路中每个传输链路与各个小区之间的映射关系。也即当终端101需要与某个小区通信时，该终端101可以从多个传输链路中任意选择至少一个传输链路与小区通信。当然，也可以预先建立每个小区和至少一个传输链路之间的映射关系，当终端101需要与某个小区通信时，使用与该小区具有映射关系的传输链路通信。
为了便于描述，下述实施例以每个小区和至少一个传输链路之间的映射关系，终端101使用多个传输链路中的至少一个传输链路(例如，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使用多个传输链路中的其他至少一个传输链路(例如，第二传输链路105)与第二网络设备103覆盖的第二小区2通信为例。
需要说明的是，本申请实施例中的第一传输链路和第二传输链路分别包括至少一个传输链路。
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，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101可以与第一小区1和第二小区2通信。
例如，终端101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 Mobile Network，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，在本申请实施例中，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。
在如图2或图3所示的架构中，终端与不同小区通信时通常可以使用不同的通信能力。例如，终端与第一小区通信时具有通信能力1，与第二小区进行通信时具有通信能力2。但是终端并非每时每刻均使用通信能力2与第二小区通信。因此，在终端未在通信能力2上具有上行传输时，通信能力2处于空闲状态。
通常情况下，终端与每个网络设备覆盖的小区进行上行传输时会对应一个传输链路/天线端口/传输Rank/传输层，即N个小区，终端通常会具有N个传输链路/天线端口/传输Rank/传输层。因此，当指示终端与小区通信时的传输链路/天线端口/传输Rank/传输层为多个时，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/天线端口/传输Rank/传输层与小区进行上行传输。也即该N个传输链路/天线端口/传输Rank/传输层中不仅包括终端与该小区之间的传输链路/天线端口/传输Rank/传输层，也包括终端与其他小区之间具有的一个或者多个传输链路/天线端口/传输Rank/传输层中的至少一个。
在如图2所示的架构中，以通信能力为最大传输链路数量为例，终端101和第一网络设备102之间的第一传输链路104处于空闲状态时，终端101可以使用处于空闲状态的第一传输链路104以及终端101和第二小区之间的第二传输链路105与第二小区进行上行传输(即终端101与第二小区之间的最大传输链路数量为多个(简称2T))。
在终端101和第一网络设备102之间的第一传输链路处于非空闲状态时，终端101则使用终端101和第二小区之间具有的第二传输链路与第二小区进行上行传输(即终端101与第二小区之间的最大传输链路数量为单个(简称1T))。
网络设备可以通过确定终端与一个小区之间的传输链路在至少两个时间资源上的状态(空闲状态或者非空闲状态)，向终端发送指令，以指示终端与另一个小区通信时进行1T/2T动态切换。即在第一传输链路104处于空闲状态时，网络设备可以指示终端使用2T与第二小区进行上行传输。当网络设备确定第一传输链路104处于非空闲状态时，则网络设备可以指示终端使用1T与第二小区进行上行传输。
本申请实施例中的“2T”指：终端与一个小区1通信时，所使用的通信能力不仅包括终端与小区1之间具有的通信能力，还包括终端与其他小区之间具有的通信能力。
本申请实施例中的“1T”指：终端与一个小区1通信时，所使用的通信能力仅包括终端与小区1之间具有的通信能力，且不包括终端与其他小区之间具有的通信能力。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。
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。
终端通常与不同小区进行上行传输时具有不同的通信链路，例如，终端与至少两个小区通信时会具有至少两个发射链路，终端与第一小区和第二小区分别使用不同的发射链路通信(例如，Tx1和Tx2，其中Tx1用于与第一小区通信，Tx2用于与第二小区通信)。由于终端并非每时每刻均与第一小区或者第二小区进行上行传输。因此，在终端未与第一小区进行上行传输时，终端与第一小区之间的Tx1通常处于空闲状态。在终端未与第一小区进行上行传输时，如果终端可以利用Tx1和Tx2与第一小区进行上行传输可以提升与第二小区之间的发送数据率。基于此，如果终端可以基于与第一小区之间的Tx1上是否 进行上行传输，动态切换与第二小区之间的发射链路，即当终端与第一小区之间具有上行传输时，终端与Tx2与第二小区进行上行传输，即1T。当终端与第一小区之间不具有上行传输时，终端与第二小区使用Tx1和Tx2进行上行传输，即2T。
但是，终端向小区发送上行数据时，通常可以利用下行控制信息(down control information，DCI)格式(Format)0_1中的探测参考信号(Sounding Reference Signal，SRS)resource indicator字段，确定物理上行共享信道(Physical UplinkShared Channel，PUSCH)关联的SRS资源集合(resource set)中的SRS resource索引(index)，子帧n中的SRI字段与子帧n之前距离子帧n最近的已发送的SRS资源集合相关联。因此，终端可以采用与该已发送的SRS资源集合中SRS resource索引所指示的SRS resource配置的port数目向小区发送上行数据。即如果最近的已发送的SRS资源集合配置的port数目为2T，则终端使用2T发送上行数据。如果最近的已发送的SRS资源集合配置的port数目为1T，则终端使用1T发送上行数据。但是，在网络设备指示终端进行1T/2T动态切换过程中，可能会出现网络设备指示终端使用2T发送上行数据，但是终端根据SRI字段所确定的发送上行数据所能采用的天线port数目为1T，即网络设备指示终端使用2T发送上行数据，与终端根据SRI字段确定的SRS资源的port数量为1T不匹配的问题，此时终端不确定自己是采用1T或者2T进行上行数据的发送。基于此，本申请实施例提供一种数据发送的方法，通过终端获取用于确定与网络设备通信时所使用的通信能力，然后从已发送的SRS资源集合中确定距离承载所述上行数据授权信息的下行控制信道最近且与发送所述上行数据时使用的通信能力数量相同的SRS资源集合。这样可以避免现有技术中存在的问题。
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。
本申请实施例中一种数据发送的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。一种指示上行传输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备中的装置，例如，芯片。下述实施例仅以数据发送的方法的执行主体为终端，另一种指示上行传输的方法的执行主体为网络设备为例。
如图6所示，本申请实施例提供一种数据发送的方法和指示上行传输的方法交互的流程示意图，该方法包括：
S101、网络设备向终端发送第一指示信息，该第一指示信息用于指示终端向网络设备发送上行数据的通信能力。
一方面，在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：此处的向终端发送第一指示信息的网络设备可以为第一小区所属的网络设备，终端向网络设备发送上行数据的通信能力中的网络设备可以为第二小区所属的网络设备。例如，在图2所示的系统架构中，发送第一指示信息的网络设备可以为第一网络设备102，终端向网络设备发送上行数据的通信能力中的网络设备可以为第二网络设备103。此处的发送第一指示信息的网络设备和终端向网络设备发送上行数据的通信能力的网络设备也可以为同一个网络设备，例如，均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。
示例性的，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Rank数和最大天线端口数目。
示例性的，该第一指示信息可以由网络设备以动态配置方式配置给终端。
一种可能的实现方式，该第一指示信息可以携带在下行控制信息(Down Control Information，DCI)中。
例如，网络设备在下发给终端的下行控制信息中增加新的信令(例如，第一指示信息)，用于指示终端确定发送上行数据时使用的通信能力。
以通信能力为最大天线端口数目为例，即第一指示信息用于指示终端使用的最大天线端口数目为2T或者使用的最大天线端口数目为1T。其中，终端使用最大天线端口数目为2T进行上传传输时的数据率大于终端使用最大天线端口数目为1T进行上传传输时的数据率。
另一种可能的实现方式，该第一指示信息可以携带在终端和其他终端共用的组公共下行控制信道中。
例如，网络设备可以通过在共用的组(group)公共下行控制信道增加第一指示信息。当第一指示信息携带在共用的组公共下行控制信道中时，该group内的所有的终端在相应的时间资源(例如，时隙(slot))上采用网络设备所指示的通信能力进行上行传输。
例如，一个group内包括终端1和终端2，第一指示信息用于指示终端在时间资源1上使用通信能力1进行上行传输。在时间资源2上使用通信能力2进行上行传输。则终端1和终端2分别在时间资源1上使用通信能力1与各自对应的小区进行上行传输。终端1和终端2分别在时间资源2上使用通信能力2与各自对应的小区进行上行传输。
示例性的，下行控制信道可以为物理下行控制信道(Physical Downlink Control Channel，PDCCH)，因此，第一指示信息可以携带在group common PDCCH发送给终端。
此外，网络设备还可以使用其他方式向终端配置第一指示信息，本申请实施例对此不作限定。
本申请实施例中对第一指示信息的大小不作限定，示例性的，该第一指示信息的大小可以为1比特(bit)。
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向网络设备发送上行数据。其中，第一通信能力大于第二通信能力。
第一通信能力大于第二通信能力指：终端在使用第一通信能力向网络设备发送上行数据时所能达到的效果(例如，发送数据率)大于终端使用第二通信能力向网络设备发送上行数据时所能达到的效果。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。
一种示例，该第一指示信息用于指示终端与网络设备通信时的通信能力为第一通信能力。
其中，第一通信能力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2T。
例如，以最大传输链路数量为2T为例，是指最大传输链路数量为两个或两个以上，该两个或两个以上的传输链路中至少包括终端与小区1之间具有的传输链路，以及至少一个终端与其他小区之间具有的传输链路。最大传输层数量/最大传输秩Rank数量/最大天线端口数量为2T的描述可以参考最大传输链路数量为2T的描述，此处不再赘述。
示例性的，第一指示信息可以为第一指示符，该第一指示符用于指示终端与网络设备通信时的最大传输链路数量为2T。例如，第一指示符为“1”。
另一种示例，该第一指示信息用于指示终端发送上行数据时使用的通信能力为第二通信能力。
第二通信能力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1T。
其中，以最大天线端口的数量为1T。例如，第一指示信息为第二指示符，第二指示符可以为“0”。
例如，以最大天线端口的数量为1T为例，是指最大天线端口包括至少一个天线端口，该至少一个天线端口至少包括终端与小区1之间具有的最大天线端口，且不包括终端与其他小区之间具有的至少一个天线端口。最大传输层数量/最大传输秩Rank数量/最大传输链路数量为1T的描述可以参考最大传输链路数量为1T的描述，此处不再赘述。
S102、终端获取网络设备发送的第一指示信息。
S103、网络设备在第一时刻向终端发送第一调度信息，该第一调度信息用于调度终端发送上行数据。
其中，第一调度信息可以由与终端通信的小区所属的网络设备发送给终端，也可以由其他小区所属的网络设备发送给终端。
S104、终端在第一时刻接收第一调度信息。
S105、终端从第一时刻之前发送的SRS资源集合中，确定与第一指示信息所指示的通信能力相同的SRS资源集合，作为第一SRS资源集合。
一种可能的实现方式，步骤S105可以通过以下方式实现：终端确定发送上行数据使用的通信能力为第一通信能力，终端从第一时刻以前已发送的SRS资源集合中选择与第一通信能力相同的SRS资源集合作为第一SRS资源集合，并根据第一探测参考信号SRS资源集合使用第一通信能力向网络设备发送上行数据。终端确定发送上行数据使用的通信能力为第二通信能力，终端从第一时刻以前已发送的SRS资源集合中选择与第二通信能力相同的SRS资源集合作为第一SRS资源集合，并根据第一探测参考信号SRS资源集合使用第二通信能力向网络设备发送上行数据。
例如，第一通信能力包括最大传输链路数量为2T，则终端确定发送上行数据的最大天线端口的数量为2T，则终端从第一时刻之前已发送的SRS资源集合中寻找与承载上行数据授权信息的下行控制信道最近，且SRS资源集合具有的最大天线端口的数量为2T作为第一SRS资源集合。
由于SRI指示的SRS集合中的具体的某一个资源，该资源可以和上行数据发送的其他参数有关，比如功率控制，上行波束(beam)指示相关，因此，可以根据所指示的天线端口的数量确定上行数据与哪个SRS资源集合关联，便于后续根据SRI指示从与上行数据关联的SRS资源集合中确定SRI指示的SRS资源。
S106、终端根据第一探测参考信号SRS资源集合使用通信能力发送上行数据。
具体的，终端可以使用上行数据信道向网络设备发送上行数据。例如，上行数据信道可以为物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。
S107、网络设备根据第一指示信息所指示的通信能力接收终端发送的上行数据。
例如，第一指示信息所指示的通信能力包括的最大天线端口数目为2T，则网络设备基于最大天线端口数目为2T接收终端发送的上行数据。
又例如，第一指示信息所指示的通信能力包括的最大传输链路数量为1T，则终端网络设备基于最大天线端口数目为1T接收终端发送的上行数据。
又例如，第一指示信息所指示的通信能力包括的最大传输Rank数为2T，则网络设备基于最大传输Rank数为2T接收终端发送的上行数据。
需要说明的是，在设备到设备(device-to-device，D2D)通信系统下，该D2D通信系统包括多个终端，则第一指示信息、第二指示信息以及第一调度信息，还可以由与终端通信的其他终端发送给该终端，本申请实施例对此不作限定。
本申请实施例提供一种数据发送的方法，通过终端获取用于确定终端向网络设备发送上行数据时使用的通信能力的第一指示信息，并根据第一指示信息确定发送上行数据关联的已发送的一个或者多个SRS资源集合中与距离承载上行数据的授权信息的下行控制信道最近且与第一指示信息所指示的通信能 力相同的SRS资源集合。这样不仅在实现传输链路共享的情况下，提高传输链路使用率，提升上行传输速率，且可以避免PUSCH所采用的通信能力与最接近的已发送的SRS资源集合对应的通信能力不匹配的问题。
作为本申请的另一个实施例，在本申请实施例提供的方法还包括：第一指示信息指示终端与网络设备通信时的传输链路数量/天线端口数目/传输Rank数量/传输层数量为2T的任一个，终端确定第一SRS资源集合关联的通信能力包括以下任一项：最大传输链路数量/最大天线端口数目/最大传输Rank数量/最大传输层数量为2T。这样终端便可以使用所指示的通信能力和网络设备通信，从而提高上行数据的传输速率。
以图2所示的系统架构为例，当网络设备为与终端具有连接的第一网络设备102时，其他网络设备可以为与终端具有连接的第二网络设备103。
示例性的，终端与网络设备1之间的传输链路包括：传输链路1、传输链路2以及传输链路3。终端与网络设备2之间具有的传输链路包括：传输链路4和传输链路5。则第一指示信息指示终端与网络设备1通信时的最大传输链路数量为2T时，终端可以使用传输链路1、传输链路2、传输链路3以及传输链路4向网络设备1覆盖的小区发送上行数据。或者终端使用传输链路1、传输链路2、传输链路3、传输链路4以及传输链路5向网络设备1覆盖的小区发送上行数据。
又一示例，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，网络设备为第二网络设备103为例，当第一指示信息指示终端向第二网络设备103覆盖的小区发送上行数据时的最大传输链路数量为1T时，终端和第二网络设备103使用第一传输链路104或第二传输链路105。
可以理解的是，为了使得终端与网络设备覆盖的小区之间进行上行传输时的最大传输链路数量为2T，不影响终端与其他小区之间进行的上行传输，则终端与小区之间的进行上行传输时的最大传输链路包括：终端与该小区之间的一个或者多个传输链路中的至少一个，以及终端与其他小区之间的一个或者多个传输链路中处于空闲状态的传输链路。
作为本申请的另一个实施例，在本申请实施例提供的方法还包括：第一指示信息指示终端与所述网络设备通信时的最大传输链路数量/最大天线端口数目/最大传输Rank/最大传输层数量为1T或者单个时，终端确定第一SRS资源集合关联的通信能力包括的最大传输链路数量/最大天线端口数目/最大传输Rank/最大传输层数量为单个或者1T。这样终端便可以在后续需要发送上行数据时，从已发送SRS资源集合中确定最大传输链路数量为单个的SRS资源集合作为第一SRS资源集合，并根据最大传输链路数量为单个发送上行数据。
示例性的，结合上例，第一指示信息指示终端与网络设备1覆盖的小区通信时的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、传输链路3与网络设备1覆盖的小区进行上行传输。或者终端使用传输链路1、传输链路2、与网络设备1覆盖的小区进行上行传输。
示例性的，第一指示信息为第一指示符，则终端确定通信能力包括的最大传输层数量/最大传输Rank数量/最大天线端口数目/最大传输链路数量为多个。第一指示信息为第二指示符，则终端确定通信能力包括的最大传输层数量/最大传输Rank数量/最大天线端口数目/最大传输链路数量为单个。
由于目前可以通过时隙聚合(slot aggregation)的调度方式调度多个时隙，即一个DCI可以调度多个slot，该多个slot调度相同的数据，因为每次调度了多个slot，但并不能保证多个slot采用相同的天线端口数目发送，可选的，作为本申请的另一个实施例，如图7所示，本申请实施例提供的方法还包括：
S108、网络设备向终端发送第二指示信息，该第二指示信息用于指示多个时间资源中采用第一指示信息所指示的通信能力发送所述上行数据的时间资源。
可以理解的是，以通信能力包括的最大传输链路数量为多个为例，该第二指示信息用于指示多个时 间资源中采用最大传输链路数量为多个发送上行数据的时间资源以后，终端便可以确定多个时间资源中除采用最大传输链路数量为多个发送上行数据的时间资源以外的其他时间资源采用最大传输链路数量为单个发送上行数据。当然，步骤S107中的第二指示信息还可以用于指示多个时间资源中采用单个传输链路发送所述上行数据的时间资源，这样终端便可以确定多个时间资源中除采用单个传输链路发送上行数据的时间资源以外的其他时间资源采用多个传输链路发送上行数据。
需要说明的是，多个传输链路的含义与传输链路的数量为多个的含义等价。单个传输链路的含义与传输链路的数量为单个的含义等价。
其中，多个时间资源可以为时隙或者符号。
本申请实施例中第二指示信息和第一指示信息可以携带在同一个消息或者同一个下行控制信道中发送给终端。
S109、终端获取第二指示信息。
可选的，终端在步骤S108之后便可以确定多个时间资源中使用第一指示信息所指示的通信能力发送上行数据的时间资源。
例如，第一指示信息指示的通信能力为第一通信能力，则终端可以确定多个时间资源中使用第一指示信息所指示的第一通信能力发送上行数据的时间资源。以及在多个时间资源中处使用第一通信能力发送上行数据的时间资源以外，使用其他通信能力发送上行数据的时间资源。
在这种情况下，作为另一种可能的实现方式，本申请实施例中的步骤S106还可以通过以下方式实现：终端在第二指示信息所指示的时间资源内根据第一SRS资源集合使用第一通信能力向网络设备发送上行数据。终端在多个时间资源中除在第二指示信息所指示的时间资源以外的时间资源根据第一SRS资源集合采用第二通信能力向网络设备发送上行数据。
以该第二指示信息携带在下行控制信息中为例，该第二指示信息可以以duration或者bitmap信息(包括至少一个第一比特或者第二比特，其中，第一比特用于指示采用多个传输链路，第二比特用于指示采用单个传输链路。
例如，第一比特为1，第二比特为0形式存在。例如。比如一个DCI一次调度了4个slot(如图8所示的时隙1～时隙4)，那么网络设备需要向终端指示在该4个slot中的哪几个slot中向网络设备发送上行数据时，使用多个第一通信能力，可以在下行控制信息中增加bitmap信息1010来指示终端。则终端便可以确定时隙1和时隙3中向网络设备发送上行数据使用第一通信能力(即图8中的2T)，时隙2和时隙4中向网络设备发送上行数据使用第二通信能力(即图8中的1T)。
本申请实施例中第一SRS资源集合包括一个或者多个SRS资源，该一个或者多个SRS资源中每个SRS资源具有相同的通信能力。
可选的，第一调度信息还包括SRI，作为本申请的另一个实施例，本申请实施例提供的方法还包括：终端根据第一调度信息包括的SRI从第一SRS资源集合中选择SRI所指示的SRS资源发送上行数据。
具体的，终端可以根据SRS资源指示(SRS resource indicator，SRI)确定第一SRS资源集合中的resource index，并根据resource index从第一SRS资源集合中选择SRI所指示的SRS资源发送上行数据。
可选的，该SRI可以携带在格式为0或格式为1的DCI中发送给终端。
具体的，步骤S107可以通过以下方式实现：第一指示信息指示的通信能力为第一通信能力，网络设备按照第一通信能力接收终端发送的上行数据。或者第一指示信息指示的通信能力为第二通信能力，网络设备按照第二通信能力接收终端发送的上行数据。
此外，步骤S107还可以通过以下方式实现：网络设备在第二指示信息所指示的时间资源内按照第一通信能力接收终端发送的上行数据。网络设备在多个时间资源除第二指示信息所指示的时间资源以外 的时间资源按照第二通信能力接收终端发送的上行数据。
