下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
为了便于更加清晰地理解本公开各实施例的技术方案，首先对本公开各实施例相关的一些技术内容进行介绍。
1、下行联合发送
多点协同传输，包括下行联合发送，支持服务小区和协作小区根据一定策略选择相同时频资源传输相同数据流，或传输不同数据流。
发送相同数据流时，期望用户设备(User Equipment，UE)收到的不同的传输接收点(Transmitting Receiving Point，TRP)发送的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)到达时间对齐满足一定要求，从而在UE接收窗口内进行信号叠加，获得较高的增益。假设两个TRP采用相同数据流传输，理论上可以获得最高6dB的增益，如果使用不同数据流传输，最高只能获得3dB增益，即损失了3dB的相干接收增益。然而，发送相同数据流对不同基站或TRP发送的PDSCH到达UE时间对齐有严格要求，如果不满足要求会导致符号间干扰(Inter Symbol Interference，ISI)从而降低增益甚至出现负增益。
2、以用户为中心的接入网架构
随着移动通信网络的发展，为了满足超密集组网场景实时大带宽业务的需求，出现了以用户为中心的接入网架构。通过引入灵活小区，组织跨网络设备下辖的多个接入点(Access Point，AP)或多个TRP协同传输、服务于一个UE，从而提升用户的体验。
图1为相关技术提供的以用户为中心的接入网架构的示意图。如图1所示，网络侧控制单元(Control Unit，CU)或数据单元(Data Unit，DU)确定组织灵活小区，由TRP3、TRP4、TRP8服务于UE1，为TRP3、TRP4、TRP8配置部分或全部相同的接入和传输资源。其中，各部分介绍如下：
(1)CU作为控制面锚节点，具有无线资源控制(Radio Resource Control，RRC)连接建立、维护和释放；承载建立、配置、维护、释放；UE测量报告管理等，UE上下文管理和分发；候选TRP集配置；DU选择等功能。
(2)DU作为数据调度实体，具有选择具体的TRP为用户执行寻址、分发、调度传输等功能。
(3)TRP是一个数据收发节点，承担射频和快速傅里叶变换(Fast Fouier Transformation，FFT)等部分物理层功能。根据实际设备功能差异，该节点也可以是承载更多的功能的接入点AP设备，也可以是各类简化功能配置的基站。
(4)灵活小区：一个或多个AP/TRP组成的具有部分/全部相同接入和传输参数的区域，由控制面单元CU为终端灵活开启和配置AP/TRP候选集，即覆盖区域可变，一个灵活小区的AP/TRP可以由数据面单元DU灵活组织。对于任一终端来说，负责提供调度决策的DU可称作主DU，仅提供AP/TRP资源、不做调度决策的可称作辅DU。
图2为本公开实施例提供的数据发送方法的流程示意图，如图2所示，该方法应用于网络设备，包括以下步骤：
步骤200、确定网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息。
步骤201、基于时间差信息，对终端进行下行数据联合发送。
具体地，本公开实施例中的网络设备可以是基站，基站下辖多个网络节 点，本公开实施例中的网络设备可以包括控制单元和控制单元连接的多个数据单元，每个数据单元下辖多个网络节点。
其中，控制单元也可以解释为集中单元(Centralized Unit)，数据单元也可以解释为分布单元(Distributed Unit)，控制单元和数据单元可以在地理上分开布置。
网络节点可以是具有向终端发送信息和接收终端发送的信息的功能的节点，在一些实施例中，网络节点可以包括TRP；或者，网络节点可以包括AP；或者网络节点可以包括TRP和AP。
在对某一个终端进行下行联合发送之前，网络设备可以先确定其下辖的多个网络节点发送的下行信号到达该终端的时间差信息。
在一些实施例中，下行信号可以包括同步信号块(Synchronization Signal Block，SSB)、追踪参考信号(Tracking Reference Signal，TRS)、信道状态信息参考信号(Channel-State Information Reference Signal，CSI-RS)中的一种或多种。
时间差信息可以是任何用于表示网络设备下辖的多个不同网络节点发送的下行信号到达终端的时间差异的信息，本公开实施例对时间差信息的形式不作限定。例如，时间差信息可以包括网络设备下辖的多个网络节点中的任意两个网络节点发送的下行信号到达终端的时间之差的信息；或者，时间差信息可以包括网络设备下辖的多个网络节点的下行参考信号时间差(DownLink Reference Signal Time Difference，DL RSTD)信息。
可以理解的是，由于不同网络节点到终端之间的距离不同，不同网络节点同时向终端发送下行信号，但终端接收到不同网络节点发送的下行信号的时间是不同的。因此，网络设备可以在确定其下辖的多个网络节点发送的下行信号到达终端的时间差信息后，基于时间差信息对该终端进行下行数据的联合发送。
本公开实施例提供的数据发送方法，通过网络设备基于其下辖的多个网络节点发送的下行信号到达终端的时间差信息，选择不同的联合传输方式或者对联合发送的过程进行调整后对该终端进行下行数据联合发送，从而可以 在不同的场景下选择增益更优的方案进行下行数据传输，提高用户的吞吐量和系统容量。
在一些实施例中，基于时间差信息，对终端进行下行数据联合发送，包括：
在终端的候选网络节点中至少两个网络节点发送的下行信号到达终端的时间差小于或等于第一门限的情况下，采用相同数据流联合传输方式对终端进行下行数据联合发送。
具体地，终端的候选网络节点可以是网络设备选择的比较适合于对终端进行下行数据传输的网络节点，网络设备可以根据时间差信息从终端的候选网络节点中确定用于做下行数据联合发送的网络节点。
在候选网络节点中至少两个网络节点发送的下行信号到达终端的时间差小于或等于第一门限的情况下，例如至少两个网络节点发送的下行信号到达终端的时间之差小于或等于第一门限，或者，至少两个网络节点对应的DL RSTD之差小于或等于第一门限，网络设备可以确定采用相同数据流联合传输方式对终端进行下行数据联合发送。
可以理解的是，用于对终端发送相同数据流的网络节点，可以是候选网络节点中满足时间差小于或等于第一门限条件的至少两个网络节点。例如，候选TRP中，TRP1、TRP2和TRP3中任意两个TRP发送的下行信号到达终端的时间之差均小于或等于第一门限，可以选择TRP1、TRP2和TRP3中的任意两个TRP对终端发送相同数据流，或者，可以选择TRP1、TRP2和TRP3对终端发送相同数据流。
选择满足时间差小于或等于第一门限条件的网络节点来对终端发送相同数据流，可以保证终端接收多个网络节点发送相同数据流的时间满足对齐要求，从而可以在合并相同数据流时获得较高的增益。
在一些实施例中，基于时间差信息，对终端进行下行数据联合发送，包括：
在终端的候选网络节点发送的下行信号到达终端的时间差均大于第一门限的情况下，采用不同数据流联合传输方式对终端进行下行数据联合发送。
具体地，终端的候选网络节点可以是网络设备选择的比较适合于对终端进行下行数据传输的网络节点，网络设备可以根据时间差信息从终端的候选网络节点中确定用于做下行数据联合发送的网络节点。
在候选网络节点发送的下行信号到达终端的时间差均大于第一门限的情况下，例如任意两个候选网络节点发送的下行信号到达终端的时间之差均大于第一门限，或者，任意两个候选网络节点对应的DL RSTD之差均大于第一门限，网络设备可以确定采用不同数据流联合传输方式对终端进行下行数据联合发送。
例如，候选TRP为TRP1、TRP2和TRP3，其中任意两个TRP发送的下行信号到达终端的时间之差均大于第一门限，可以采用不同数据流联合传输方式对终端进行下行数据联合发送。
在候选网络节点发送的下行信号到达终端的时间差均大于第一门限的情况下，终端接收的相同数据流不满足对齐要求，可能降低增益甚至产生负增益，因此在这种情况下采用不同数据流联合传输方式对终端进行下行数据联合发送，相比于采用相同数据流联合传输方式，可以获得更稳定的增益。
在一些实施例中，基于时间差信息，对终端进行下行数据联合发送，包括：
基于时间差信息，调整终端的候选网络节点的数据发送时间窗，采用相同数据流联合传输方式对终端进行下行数据联合发送。
具体地，终端的候选网络节点可以是网络设备选择的比较适合于对终端进行下行数据传输的网络节点，网络设备可以基于时间差信息对候选网络节点的数据发送时间窗进行调整，使得调整后的候选网络节点向终端发送相同数据流，终端接收各个候选网络节点发送的相同数据流的时间满足对齐要求。
本公开实施例中网络设备对候选网络节点的数据发送时间窗的具体调整方式不作限定，例如，可以选择一个参考网络节点，根据其他网络节点与该参考网络节点之间的时间差来调整其他网络节点的数据发送时间窗等。
基于时间差信息，对各个候选网络节点的数据发送时间窗进行调整，可以保证终端接收多个网络节点发送相同数据流的时间满足对齐要求，从而可 以在合并相同数据流时获得较高的增益。
在一些实施例中，确定网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息，包括：
接收终端上报的测量信息，测量信息包括网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息；或者，
将终端发送的上行信号到达网络设备下辖的多个网络节点的时间差信息，作为网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息。
具体地，一些实施方式中，网络设备可以接收终端上报的测量信息，该测量信息包括网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息，从而网络设备可以确定网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息。
在一些实施例中，接收终端上报的测量信息，包括：
接收终端通过测量事件报告、媒体接入控制层控制元素MAC CE或上行控制信息UCI上报的测量信息。
具体地，网络设备可以预先对终端进行配置，终端可以按照网络设备的配置对网络设备下辖的多个网络节点发送的下行信号进行测量，并将网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息上报给网络设备。
终端可以通过测量事件报告上报测量信息；或者，终端可以通过媒体接入控制层控制元素(Medium Access Control Control Element，MAC CE)上报测量信息；或者，终端可以通过上行控制信息(Uplink Control Information，UCI)上报测量信息。
例如，如表1所示，其中R为保留位，Ci字段代表配置给UE进行TRP测量的按顺序的标识，标志是否触发DL RSTD上报。如果Ci为1，上报表示TRPi的DL RSTD，如果Ci为0，表示辅DU所辖TRPi的字段不存在或者不上报。
表1终端通过MAC CE上报的举例

一些实施方式中，网络设备中的多个网络节点可以接收终端同时发送的上行信号，例如探测参考信号(Sounding Reference Signal，SRS)或用于定位的探测参考信号(Sounding Reference Signal for positioning purposes，SRS-Pos)或解调参考信号(Demodulation Reference Signal，DMRS)等，然后进行测量得到终端发送的上行信号到达网络设备下辖的多个网络节点的时间差信息，例如网络设备测量多个网络节点的上行相对到达时间(UpLink Relative Time of Arrival，UL RTOA)，计算得到时间差信息。
在满足上下行信道互易性的场景下，网络设备可以将终端发送的上行信号到达网络设备下辖的多个网络节点的时间差信息，作为网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息。
将终端发送的上行信号到达网络设备下辖的多个网络节点的时间差信息，作为网络设备下辖的多个网络节点发送的下行信号到达终端的时间差信息，可以简化网络设备确定终端发送的上行信号到达网络设备下辖的多个网络节点的时间差信息的过程，减少资源消耗。
在一些实施例中，接收终端通过测量事件报告上报的测量信息，包括：
接收终端通过第一测量事件的事件报告上报的测量信息；
其中，第一测量事件用于表示不同网络节点发送的下行信号到达同一终端的时间差测量结果是否满足下行联合发送相同数据流的时间对齐要求。
具体地，网络设备可以向终端配置第一测量事件，例如可以通过RRC消息向终端配置第一测量事件。第一测量事件用于表示不同网络节点发送的下行信号到达同一终端的时间差测量结果是否满足下行联合发送相同数据流的 时间对齐要求。
终端根据网络设备配置的第一测量事件，对网络设备下辖的多个网络节点发送的下行信号的时间差进行测量并获取时间差测量结果，判断时间差测量结果是否满足下行联合发送相同数据流的时间对齐要求，通过相应的事件报告向网络设备上报测量信息。
在一些实施例中，接收终端通过第一测量事件的事件报告上报的测量信息，包括：
接收终端通过第一测量事件的第一事件报告上报的测量信息；
其中，第一事件报告用于指示时间差测量结果满足下行联合发送相同数据流的时间对齐要求。
具体地，网络设备可以向终端配置不同网络节点发送的下行信号到达同一终端的时间差测量结果满足下行联合发送相同数据流的时间对齐要求的触发条件。
例如，在多个网络节点中至少两个网络节点发送的下行信号到达终端的时间差小于第二门限的情况下，判断时间差测量结果满足下行联合发送相同数据流的时间对齐要求。
在终端判断时间差测量结果满足下行联合发送相同数据流的时间对齐要求的情况下，可以通过第一测量事件的第一事件报告上报测量信息，第一事件报告用于指示时间差测量结果满足下行联合发送相同数据流的时间对齐要求。
其中，本公开实施例对第一事件报告指示时间差测量结果满足下行联合发送相同数据流的时间对齐要求的方式不作限定，例如可以通过设置或不设置某个字段指示，或者携带指示信息等。
网络设备接收终端通过第一事件报告上报的测量信息后，可以根据第一事件报告确定采用相同数据流联合传输方式对终端进行下行数据联合发送，然后根据测量信息确定用于下行数据联合发送的网络节点。
在一些实施例中，接收终端通过第一测量事件的事件报告上报的测量信息，包括：
接收终端通过第一测量事件的第二事件报告上报的测量信息；
其中，第二事件报告用于指示时间差测量结果不满足下行联合发送相同数据流的时间对齐要求。
具体地，网络设备可以向终端配置不同网络节点发送的下行信号到达同一终端的时间差测量结果不满足下行联合发送相同数据流的时间对齐要求的触发条件。
例如，在多个网络节点发送的下行信号到达终端的时间差均大于第三门限的情况下，判断时间差测量结果不满足下行联合发送相同数据流的时间对齐要求。
在终端判断时间差测量结果不满足下行联合发送相同数据流的时间对齐要求的情况下，可以通过第一测量事件的第二事件报告上报测量信息，第二事件报告用于指示时间差测量结果不满足下行联合发送相同数据流的时间对齐要求。
其中，本公开实施例对第二事件报告指示时间差测量结果不满足下行联合发送相同数据流的时间对齐要求的方式不作限定，例如可以通过设置或不设置某个字段指示，或者携带指示信息等。
网络设备接收终端通过第二事件报告上报的测量信息后，可以根据第二事件报告确定采用不同数据流联合传输方式对终端进行下行数据联合发送，然后根据测量信息确定用于下行数据联合发送的网络节点。
在一些实施例中，该方法还包括：
网络设备的控制单元CU确定时间差信息之后，网络设备的CU将时间差信息发送给网络设备的主数据单元DU。
具体地，在网络设备包括CU和CU连接的多个DU，每个DU下辖多个网络节点的情况下，可以由CU确定时间差信息。
由于主DU负责提供调度决策，CU可以将时间差信息发送给主DU，由主DU基于时间差信息对终端进行下行数据联合发送。
在一些实施例中，该方法还包括：
网络设备的CU基于时间差信息，确定终端的候选网络节点所对应的数 据发送时间窗调整信息；
网络设备的CU将数据发送时间窗调整信息发送给网络设备的主DU。
具体地，在网络设备包括CU和CU连接的多个DU，每个DU下辖多个网络节点的情况下，可以由CU基于时间差信息，确定终端的候选网络节点所对应的数据发送时间窗调整信息。
CU确定终端的候选网络节点所对应的数据发送时间窗调整信息后，可以将数据发送时间窗调整信息发送给主DU。
一些实施方式中，CU可以将数据发送时间窗调整信息同时发送给主DU和辅DU，由主DU和辅DU调整向各自所辖的候选网络节点转发数据的时间窗；或者，由主DU和辅DU通知各自所辖的候选网络节点对数据发送时间窗进行调整，使得各DU所辖的候选网络节点可以根据数据发送时间窗调整信息调整发送数据的时间窗。从而，终端接收各个候选网络节点发送的相同数据流的时间可以满足对齐要求。
在一些实施例中，该方法还包括：
在网络设备的主DU基于时间差信息确定终端的候选网络节点所对应的数据发送时间窗调整信息，或者网络设备的主DU接收网络设备的CU发送的终端的候选网络节点所对应的数据发送时间窗调整信息之后，网络设备的主DU将数据发送时间窗调整信息发送给网络设备的辅DU。

本公开各实施例提供的方法是基于同一申请构思的，因此各方法的实施可以相互参见，重复之处不再赘述。
以下通过具体应用场景的实施例对本公开各上述实施例提供的方法进行举例说明。
实施例一：
该实施例适用于CU和DU分开设置的场景。图4为本公开实施例提供的网络侧进行调度的流程示意图，如图4所示，该流程包括以下步骤：
1、网络侧(CU)获得UE上报的不同TRP的DL RSTD。
2、网络侧交互获得(即CU发送给DU)不同TRP的DL RSTD。
3、网络侧(主DU)根据DL RSTD判断候选TRP是否满足相同流调度 条件。
4、若满足相同流调度条件，主DU将相应的TRP加入发送相同流TRP集合进行相同流调度，流程结束；若不满足相同流调度条件，跳转到步骤5。
5、判断各TRP是否支持调整发送时间窗，其判断依据是该调整是否会影响其他用户的数据发送。若支持，主DU根据DL RSTD调整各TRP的发送时间窗后进行相同流调度；若不支持，主DU将相应的TRP加入发送不同流TRP集合进行不同流调度。
实施例二：
该实施例适用于CU和DU合并设置的场景，或者CU进行调度的场景。
网络侧进行调度的流程包括以下步骤：
1、网络侧获得UE上报的不同TRP的DL RSTD。
2、网络侧(CU或主DU)根据DL RSTD判断候选TRP是否满足相同流调度条件。
3、若满足相同流调度条件，CU或主DU将相应的TRP加入发送相同流TRP集合进行相同流调度，流程结束；若不满足相同流调度条件，跳转到步骤4。
4、判断各TRP是否支持调整发送时间窗，其判断依据是该调整是否会影响其他用户的数据发送。若支持，CU或主DU根据DL RSTD调整各TRP的发送时间窗后进行相同流调度；若不支持，CU或主DU将相应的TRP加入发送不同流TRP集合进行不同流调度。
实施例三：在RRC消息(例如ReportConfigNR)中新增一个事件(Event)：Event T1。基站通过RRC消息配置Event T1并且配置门限值：T1事件迟滞量t1_hysteresis和T1事件偏移量t1_offset。
UE以主DU所辖TRP作为参考TRP，对邻DU所辖TRP进行DL RSTD测量，当UE测量结果满足公式1或公式2的时候，上报T1事件报告，在新增参数MeasResultNeighTrpss中填写UE测量DL RSTD的测量结果。
DL RSTD<-t1_hysteresis-t1_offset      公式1
(触发满足联合传输相同流时间对齐差)
DL RSTD>t1_hysteresis-t1_offset      公式2
(触发不满足联合传输相同流时间对齐差)
其中DL RSTD单位是Tc。Tc的定义为Tc＝1/(Δfmax·Nf)，其中，Δfmax＝480×103Hz，Nf＝4096。
如果任意一个DL RSTD满足公式1，表示主DU所辖TRP和辅DU所辖TRP的时间差满足做相同流联合传输的时间对齐要求，UE在事件报告中不设置report on leave字段。
如果DL RSTD均满足公式2，表示主DU所辖TRP和辅DU所辖TRP的时间差不满足做相同流联合传输的时间对齐要求，UE在事件报告中设置report on leave字段。
CU的RRC层收到T1事件报告后，如果UE上报的事件报告没有设置report on leave字段，即认为满足相同流传输，就可以直接指示DU进行相同流传输；或者将相关信息下发给负责调度的DU，DU决策是否为UE进行相同流传输。主DU生成物理层数据后将物理层数据转发给辅DU，由辅DU发送给下辖TRP。
CU的RRC层收到T1事件报告后，如果UE上报的事件报告设置了report on leave字段，就可以指示主DU给UE进行不同流资源调度。主DU生成物理层数据，将不同流映射到主辅DU下辖的TRP，主DU将映射到主DU下辖的TRP的物理层数据流发送给其下辖的TRP，主DU将映射到辅DU下辖的TRP的物理层数据流发送给辅DU，由辅DU发送给下辖TRP。
实施例四：终端上报事件报告的过程参见实施例三所述的步骤。
CU的RRC层收到T1事件报告后，如果UE上报的事件报告设置了report on leave字段，需要通过新定义的CU到DU接口把测量结果传递给主DU，主DU物理层根据收到的DL RSTD，通知辅DU调整转发下行数据发送时间窗，以保证UE从辅DU所辖TRP接收的PDSCH的DL RSTD满足相同流联合传输的时间对齐差要求。
图5为本公开实施例提供的调整辅DU所辖TRP的PDSCH发送时间窗的示意图，如图5所示，T1时间段UE测量并上报事件报告，设置report on  leave字段。T2时间段主DU根据UE上报的事件报告，指示辅DU调整转发物理层数据时间窗。T3时间段，UE收到各TRP发送的PDSCH时间对齐满足联合发送相同流要求。
图6为本公开实施例提供的信息交互的示意图，如图6所示，主CU收到T1事件后通过CU和DU之间的时间到达接口(控制面接口)把相关测量结果(DL RSTD)传递到主DU。图中TRP1属于主DU，TRP2属于辅DU。主DU和辅DU之间通过建立隧道(tunnel)或者用户面接口来连接。主DU和TRP1之间、辅DU和TRP2之间通过前传链路连接，当前支持DU和TRP之间的接口有通用公共无线接口(Common Public Radio Interface，CPRI)和增强型通用公共无线接口(enhanced CPRI，eCPRI)等。
主DU在转发物理层数据给辅DU时，可以通知辅DU进行发送时间窗的调整。辅DU可以根据主DU的指示，根据调整的发送时间窗，转发物理层数据给辅DU所辖TRP。
